How to Cross-Reference a Capacitor
Follow this step-by-step process to find a suitable replacement capacitor from a different manufacturer. Whether you are replacing an obsolete part or sourcing an alternative, these steps will help ensure compatibility.
Identify the Original Specifications
Read the markings on the original capacitor or consult the equipment documentation. Record the manufacturer, part number, capacitance value, voltage rating, temperature rating, and physical dimensions. If the markings are illegible, check the equipment schematic or service manual for the part number. For unmarked capacitors, measure the capacitance with a meter and note the physical size and lead configuration.
Match Critical Parameters
The replacement capacitor must match or exceed these specifications (see our glossary for definitions):
- Capacitance: Same value, within the tolerance rating (typically +/-5% to +/-20%)
- Voltage rating: Equal to or higher than the original (never lower)
- ESR: Equal to or lower than the original, especially critical in switching power supplies
- Temperature rating: Must meet or exceed the original operating temperature range
- Dielectric type: Use the same type (electrolytic, film, ceramic, etc.) unless you have verified compatibility
Check Physical Dimensions
Verify that the replacement capacitor will physically fit in the mounting location. Measure the diameter, height, lead spacing, and mounting style (radial, axial, snap-in, screw terminal, or SMD). For motor capacitors, confirm whether the original is oval or round, and check the mounting bracket compatibility. For screw terminal capacitors, verify the terminal orientation and mounting hole pattern.
Verify Application Requirements
Consider the specific demands of your application. Power supply filter capacitors require low ESR and adequate ripple current handling. Motor run capacitors must be rated for continuous AC duty. Snubber capacitors need high dv/dt ratings. Safety-rated capacitors (X1, X2, Y1, Y2) must maintain their safety classification. Medical and aerospace applications may require specific approvals or certifications that limit the available replacement options.

Capacitor Cross-Reference FAQ
Answers to the most common questions about finding replacement and equivalent capacitors.
How do I find a replacement for an obsolete capacitor?
Start by identifying the original capacitor specifications from its label or datasheet: capacitance, voltage rating, temperature rating, ESR, and physical dimensions. Then search our cross-reference tool by part number or use the tables on this page to find known equivalents. Specap specializes in obsolete and hard-to-find capacitors -- contact us if you cannot locate a replacement, as we maintain extensive inventory of discontinued parts from Sprague, Mallory, Aerovox, and other legacy manufacturers.
Can I use a different brand capacitor as a replacement?
Yes, in most cases you can substitute a capacitor from a different manufacturer as long as the critical specifications match or exceed the original. The key parameters to match are capacitance value (within tolerance), voltage rating (equal or higher), temperature rating (equal or higher), ESR (equal or lower for power applications), and physical dimensions (must fit the mounting location). The dielectric type should also remain the same -- for example, replace a film capacitor with another film capacitor, not a ceramic.
What specifications must match when cross-referencing capacitors?
The essential specifications to match are: (1) Capacitance -- same value within the tolerance rating; (2) Voltage rating -- the replacement must be rated equal to or higher than the original; (3) Temperature rating -- must meet or exceed the original operating range; (4) ESR (Equivalent Series Resistance) -- critical for power supply and switching applications, must be equal or lower; (5) Physical dimensions and lead configuration -- the replacement must physically fit the mounting location; (6) Ripple current rating -- especially important for electrolytic capacitors in power applications.
Where can I find Allen-Bradley capacitor cross-references?
Allen-Bradley (Rockwell Automation) drive capacitors are commonly cross-referenced to Cornell Dubilier (CDE) equivalents. Our cross-reference table on this page covers popular Allen-Bradley part numbers for 1336 and PowerFlex drives. For the most accurate cross-reference, identify the AB part number from the capacitor label or drive documentation, then contact Specap. We stock replacement capacitors for Allen-Bradley 1336, 1305, 1397, PowerFlex 40/400/520/525/700/753/755, and other drive families.
Can I replace a 370V motor capacitor with a 440V?
Yes, you can safely replace a 370VAC motor run capacitor with a 440VAC capacitor of the same capacitance and type. The voltage rating indicates the maximum voltage the capacitor can handle, so a higher rating provides additional safety margin. However, you should never go the other direction -- never replace a 440VAC capacitor with a 370VAC unit, as this can lead to premature failure or a safety hazard. Also ensure the physical size is compatible with the mounting bracket or space available.
How do I cross-reference a computer-grade screw terminal capacitor?
Computer-grade (also called large-can or screw terminal) electrolytic capacitors are commonly used in UPS systems, power supplies, and variable frequency drives. To cross-reference these, match the capacitance, voltage, ESR, ripple current, and can diameter. Major manufacturers include Sprague/Vishay, Cornell Dubilier (CDE), Nichicon, and KEMET. Our cross-reference table on this page shows equivalents between these brands. Note that mounting hole patterns and terminal orientations may vary between manufacturers, so verify physical compatibility.
How do I find a replacement for a Sprague capacitor?
Sprague was acquired by Vishay Intertechnology, so many Sprague part numbers now have direct Vishay equivalents. For the popular 36D and 36DX computer-grade electrolytic series, Cornell Dubilier (CDE) DCMC and Nichicon LNR series are common replacements — see our cross-reference table on this page. Sprague 39D miniature electrolytics cross to Nichicon and CDE snap-in types. For Sprague Atom TVA tubular electrolytics used in vintage audio equipment, Nichicon TVX or new-production Sprague Atom capacitors (still manufactured under the Sprague heritage brand) are suitable replacements. Orange Drop film capacitors used in guitar and audio amplifiers cross to Vishay/Sprague MKP or CDE film equivalents. Always verify capacitance, voltage, and physical dimensions when substituting.
What are the modern equivalents for Aerovox motor capacitors?
Aerovox motor capacitors, particularly the Z-series motor run capacitors (Z50, Z62, Z73), are commonly replaced with Cornell Dubilier (CDE) DERA or Mars equivalents. Aerovox AGM series motor start capacitors cross to CDE or NTE motor start types — match the capacitance (typically 88-1080 uF) and voltage (110V, 165V, or 250VAC). For Aerovox industrial film capacitors like the 2779, SXB, and SXE power film series used in snubber and AC filter applications, CDE or KEMET polypropylene film capacitors are suitable replacements. Aerovox was a major U.S. capacitor manufacturer before ceasing operations, so many of their parts are now considered obsolete — contact Specap if you need help sourcing a specific Aerovox replacement.
