Equivalent & Substitute Parts for ECA-2CM010B

Part Overview

The Panasonic ECA-2CM010B is a 1 µF, 160 V aluminum electrolytic capacitor in radial, can package with a rated lifetime of 2000 hours at 85°C. This part is classified as obsolete and belongs to the M-A series. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary for ongoing design support and procurement continuity. Substitute options include direct electrical equivalents from Panasonic's active NHG-A and M-A series, as well as compatible alternatives from other manufacturers.

Substitute Part Grouping Explanation

Substitution of the ECA-2CM010B is determined by the following critical parameters: capacitance value (1 µF), voltage rating (minimum 160 V), tolerance (±20%), physical dimensions (0.248" diameter, 0.480" height, 0.197" lead spacing), and through-hole radial mounting configuration. Substitute parts are grouped into three categories:

Direct Substitutes (Same Voltage Rating, Active Status): Parts maintaining 160 V rating with identical physical footprint and capacitance. ECA-2CHG010B qualifies as a direct substitute, offering improved thermal performance (2000 Hrs @ 105°C) and automotive-grade reliability (AEC-Q200).

Upgrade Substitutes (Higher Voltage Rating, Same Footprint): Parts with voltage ratings exceeding 160 V (200 V, 250 V, 350 V, 400 V) that maintain identical physical dimensions and lead spacing. These provide enhanced voltage margin while preserving mechanical compatibility. Panasonic M-A and NHG-A series parts (ECA-2EM010B, ECA-2DHG010B, ECA-2EHG010B, ECA-2VHG010B, ECA-2VM010B, ECA-2GHG010B, ECA-2GM010B) fall into this category.

Cross-Manufacturer Substitutes: Parts from alternative manufacturers (Vishay Beyschlag, Cornell Dubilier Electronics) meeting the same electrical specifications and physical constraints. MAL214232108E3 and SK010M160ST provide functional equivalence with different thermal or performance characteristics.

Engineering Selection Recommendations

For Direct Replacement with Enhanced Reliability: ECA-2CHG010B is the primary direct substitute. It maintains identical electrical specifications (1 µF, 160 V, ±20%) and physical footprint while offering improved thermal performance (105°C operating temperature versus 85°C) and AEC-Q200 automotive qualification. This part is active and ROHS3 compliant.

For Voltage Margin Applications: When circuit design permits higher voltage ratings, Panasonic NHG-A series parts (ECA-2DHG010B at 200 V, ECA-2EHG010B at 250 V, ECA-2VHG010B at 350 V, ECA-2GHG010B at 400 V) provide enhanced voltage headroom while maintaining identical physical dimensions and 105°C thermal performance. These are active, ROHS3 compliant parts suitable for general-purpose applications.

For Thermal Performance Matching Original Specification: ECA-2EM010B and ECA-2VM010B maintain the original 85°C thermal rating while offering 250 V and 350 V voltage upgrades respectively. Both are active M-A series parts with ROHS3 compliance.

For Cross-Manufacturer Compatibility: MAL214232108E3 (Vishay Beyschlag) provides a 200 V rated alternative with extended thermal life (2500 Hrs @ 105°C) and wider operating temperature range (-40°C to 105°C). Physical dimensions differ slightly (0.197" diameter versus 0.248", height 0.492" versus 0.480"). SK010M160ST (Cornell Dubilier Electronics) matches the original 160 V rating and thermal specification but features different lead spacing (0.098" versus 0.197") and height (0.512" versus 0.480"), requiring PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can ECA-2CHG010B directly replace ECA-2CM010B without circuit modification?

A: Yes. ECA-2CHG010B maintains identical capacitance (1 µF), voltage rating (160 V), tolerance (±20%), and physical footprint (0.248" diameter, 0.480" height, 0.197" lead spacing). The part is pin-compatible and electrically equivalent. The improved operating temperature range (-25°C to 105°C versus -25°C to 85°C) and AEC-Q200 rating provide enhanced reliability without requiring design changes.

Q: What is the difference between Panasonic M-A and NHG-A series substitutes?

A: M-A series parts (ECA-2CM010B, ECA-2EM010B, ECA-2GM010B, ECA-2VM010B) are rated for 2000 hours at 85°C operating temperature. NHG-A series parts (ECA-2CHG010B, ECA-2DHG010B, ECA-2EHG010B, ECA-2VHG010B, ECA-2GHG010B) are rated for 2000 hours at 105°C operating temperature. Both series maintain identical physical dimensions and lead spacing. Selection depends on circuit thermal environment requirements.

Q: Can I use a higher voltage-rated substitute such as ECA-2GHG010B (400 V) in place of ECA-2CM010B (160 V)?

A: Yes. Higher voltage-rated parts are electrically compatible substitutes. ECA-2GHG010B maintains the same 1 µF capacitance, ±20% tolerance, and identical physical footprint. The 400 V rating provides additional voltage margin and is suitable for circuits originally designed for 160 V operation. No circuit modification is required.

Q: Are there dimensional compatibility concerns with cross-manufacturer substitutes?

A: Yes. MAL214232108E3 (Vishay Beyschlag) has a smaller diameter (0.197" versus 0.248") and slightly taller height (0.492" versus 0.480"), requiring PCB layout verification. SK010M160ST (Cornell Dubilier Electronics) features different lead spacing (0.098" versus 0.197") and greater height (0.512" versus 0.480"), necessitating PCB redesign. Panasonic substitutes maintain identical dimensions and are direct mechanical replacements.

Q: What compliance certifications apply to substitute parts?

A: All active Panasonic substitute parts listed are ROHS3 compliant and REACH unaffected. ECA-2CHG010B carries AEC-Q200 automotive qualification. Vishay MAL214232108E3 is ROHS3 compliant. Cornell Dubilier SK010M160ST is ROHS3 compliant with MSL rating of 1 (Unlimited). Compliance documentation should be verified against specific application requirements.

Q: How do ripple current ratings differ between substitutes?

A: Ripple current specifications vary by series and thermal rating. ECA-2CM010B specifies 36 mA @ 120 Hz and 61.2 mA @ 10 kHz. NHG-A series parts (ECA-2CHG010B, ECA-2DHG010B, ECA-2EHG010B, ECA-2VHG010B, ECA-2GHG010B) specify lower ripple currents (17-18 mA @ 120 Hz, 25.5-27 mA @ 100 kHz) due to enhanced thermal performance. M-A series upgrades (ECA-2EM010B, ECA-2VM010B, ECA-2GM010B) maintain higher ripple current ratings (32-34 mA @ 120 Hz, 54.4-57.8 mA @ 10 kHz) matching the original specification. Circuit ripple current requirements should be evaluated against substitute specifications.
