ECA-2CM010 Equivalent & Substitute Parts

Part Overview

The ECA-2CM010 is a 1 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This part belongs to the M-A series and is classified as obsolete. The component is rated for 2000 hours at 85°C with ±20% capacitance tolerance and is designed for general-purpose applications.

Due to its obsolete status, equivalent and substitute parts with improved specifications or active product status are necessary for new designs and ongoing production support. Suitable alternatives maintain the same capacitance and voltage rating while offering enhanced operating temperature ranges, extended lifetime ratings, or higher voltage ratings for design flexibility.

Substitute Part Grouping Explanation

Substitution for the ECA-2CM010 is determined by the following criteria:

Direct Equivalents maintain identical capacitance (1 µF), voltage rating (160 V), tolerance (±20%), package dimensions, and through-hole mounting configuration. These parts are interchangeable at the board level without design modification.

Voltage Upgrades increase the rated voltage above 160 V while maintaining 1 µF capacitance and ±20% tolerance. These parts provide enhanced voltage margin and are backward-compatible for applications operating below their rated voltage.

Temperature/Lifetime Upgrades extend the operating temperature range or improve lifetime ratings while maintaining the same capacitance, voltage, and package specifications. These upgrades enhance reliability in demanding thermal environments.

Cross-Manufacturer Equivalents from Nichicon and Cornell Dubilier / Illinois Capacitor provide identical electrical specifications and mechanical compatibility with alternative sourcing options.

Engineering Selection Recommendations

For Direct Replacement with Enhanced Temperature Performance: ECA-2CHG010 is the primary direct equivalent. It maintains 160 V rating and 1 µF capacitance with identical package dimensions. The upgrade from 85°C to 105°C maximum operating temperature and extended lifetime at elevated temperature improves reliability. This part is active and ROHS3 compliant.

For Extended Voltage Margin: ECA-2DHG010, ECA-2EM010, ECA-2VM010, ECA-2GHG010, and ECA-2GM010 provide voltage ratings of 200 V, 250 V, 350 V, and 400 V respectively. These parts are backward-compatible for circuits operating at 160 V or below and offer increased design margin. All are active products with ROHS3 compliance.

For Cross-Manufacturer Sourcing: UVR2C010MED (Nichicon) provides 160 V, 1 µF specifications with extended low-temperature operation (-40°C minimum). Case height is 0.492" versus 0.480" for the original part. This part is obsolete but available in inventory.

105CKE250M and 105CKR250M (Cornell Dubilier / Illinois Capacitor) offer 250 V ratings with identical capacitance. Both are active products. Case height is 0.492" for both variants. 105CKE250M operates to 105°C; 105CKR250M operates to 85°C.

Compliance Considerations: All active substitute parts are ROHS3 compliant. The original ECA-2CM010 and UVR2C010MED are obsolete; active alternatives are preferred for new designs.

Frequently Asked Questions (FAQ)

Q: Can ECA-2CHG010 replace ECA-2CM010 directly on the PCB? A: Yes. ECA-2CHG010 maintains identical capacitance (1 µF), voltage rating (160 V), tolerance (±20%), package type (radial can), lead spacing (2.50mm), and case diameter (6.30mm). Height is identical at 0.480". No board layout modification is required.

Q: What is the advantage of using a higher voltage-rated part like ECA-2EM010 (250 V) instead of the original 160 V part? A: Higher voltage ratings provide increased design margin and stress relief on the capacitor. A 250 V part operating at 160 V experiences lower electrical stress, potentially extending operational life and improving reliability in circuits with voltage transients or ripple.

Q: Why is ECA-2CHG010 rated for 105°C while ECA-2CM010 is rated for 85°C? A: ECA-2CHG010 belongs to the NHG-A series with enhanced thermal performance, while ECA-2CM010 is from the M-A series. The NHG-A series is designed for higher temperature operation. Both maintain 2000-hour lifetime ratings at their respective temperature limits.

Q: Are there mechanical differences between substitute parts? A: Most Panasonic substitutes (ECA-2CHG010, ECA-2DHG010, ECA-2EM010, ECA-2GHG010, ECA-2GM010, ECA-2VHG010, ECA-2VM010) maintain identical case diameter (6.30mm) and height (12.20mm). Nichicon UVR2C010MED and Cornell Dubilier parts (105CKE250M, 105CKR250M) have case height of 12.50mm. Verify PCB clearance if height variation is critical.

Q: Can I use ECA-2GHG010 (400 V) in place of ECA-2CM010 (160 V)? A: Yes, electrically and mechanically. ECA-2GHG010 is backward-compatible for any circuit designed for 160 V or lower. The 400 V rating provides substantial voltage margin. Package dimensions are identical except for the same 12.20mm height as the original part.

Q: What is the difference between ECA-2EM010 and ECA-2GM010? A: Both are 1 µF, 400 V Panasonic capacitors with ±20% tolerance. ECA-2EM010 (M-A series) is rated for 2000 hours at 85°C. ECA-2GM010 (M-A series) is also rated for 2000 hours at 85°C. Both are active products with identical specifications and package dimensions.

Q: Why would I choose a Cornell Dubilier part over Panasonic? A: Cross-manufacturer sourcing provides supply chain flexibility. 105CKE250M and 105CKR250M are active products with established availability. Both maintain 1 µF, 250 V specifications and radial can package. Case height is 12.50mm versus 12.20mm for Panasonic equivalents. Verify PCB layout clearance before substitution.

Q: Is the ECA-2CHG010 ROHS3 compliant? A: Yes. ECA-2CHG010 is ROHS3 compliant. All active substitute parts listed are ROHS3 compliant. The original ECA-2CM010 compliance status is not specified in the provided data.
