Engineering Selection Recommendations

For Direct 160 V Replacement: Select from EKMQ161ELL471MM40S, ESMQ161ELL471MM40S, 160PK470MEFC18X40, or 160PX470MEFC18X40. All are active products with ROHS3 compliance. EKMQ161ELL471MM40S and 160PX470MEFC18X40 offer extended temperature operation to 105°C. 160BXC470MEFC18X40 provides the longest operational lifetime at 12000 hours @ 105°C while maintaining 160 V rating and identical package dimensions to the original part.

For Upgraded 200 V Replacement: EKXJ201ELL471MM40S and UCY2D471MHD both deliver 12000 hours lifetime @ 105°C with extended temperature range (-40°C ~ 105°C) and ROHS3 compliance. EKXJ201ELL471MM40S includes AEC-Q200 automotive qualification. EPAG201ELL471MM40S provides 2000 hours @ 105°C operation with RoHS compliance for general purpose applications.

All substitute parts maintain identical capacitance (470 µF), tolerance (±20%), lead spacing (0.295"), and diameter (0.709") specifications. Height variations between 1.634" and 1.654" are within acceptable PCB layout tolerances for through-hole radial components.

Frequently Asked Questions (FAQ)

Q: Can I use a 200 V rated capacitor in place of the 160 V ECA-2CM471?

A: Yes. Higher voltage ratings are electrically compatible and provide additional safety margin. The 200 V alternatives (200KXW470MEFC18X40, EKXJ201ELL471MM40S, EPAG201ELL471MM40S, UCY2D471MHD) are direct functional replacements with identical 470 µF capacitance and package footprint.

Q: What is the difference between the Chemi-Con KMQ and SMQ series substitutes?

A: EKMQ161ELL471MM40S (KMQ series) operates to 105°C with 2000 hours lifetime at that temperature. ESMQ161ELL471MM40S (SMQ series) operates to 85°C with 2000 hours lifetime. Both maintain -40°C minimum operating temperature and identical electrical specifications. Selection depends on application thermal requirements.

Q: Are there height restrictions when substituting the ECA-2CM471?

A: The original part height is 1.654" (42.00 mm). Most substitutes measure 1.634" (41.50 mm), which is 0.020" shorter and acceptable for standard PCB layouts. EPAG201ELL471MM40S and all Rubycon 160 V series match the original 1.654" height exactly.

Q: Which substitute offers the longest operational lifetime?

A: 160BXC470MEFC18X40, EKXJ201ELL471MM40S, and UCY2D471MHD all provide 12000 hours lifetime @ 105°C, compared to the original 2000 hours @ 85°C. These are recommended for applications requiring extended reliability.

Q: Is the ECA-2CM471 replacement compatible with existing PCB designs?

A: Yes. All substitutes maintain the critical package parameters: 0.295" (7.50 mm) lead spacing, 0.709" (18.00 mm) diameter, and radial through-hole mounting. Height variations of ±0.020" are within standard PCB tolerance for component placement.

Q: What compliance certifications should I verify for my application?

A: All listed substitutes are ROHS3 compliant. EKXJ201ELL471MM40S includes AEC-Q200 automotive qualification. Verify REACH status requirements for your specific application; UCY2D471MHD is REACH Affected, while others are REACH Unaffected.
