Engineering Selection Recommendations

Direct Equivalent (Identical Specifications): ECA-2CM470 is a direct equivalent to ECA-2CM470B, differing only in packaging format (Bulk vs. Tape & Box). Both are Panasonic Active products with identical electrical specifications and are suitable for direct substitution in applications where packaging format does not impose constraints.

Upgrade Options (Enhanced Performance):

Panasonic upgrades ECA-2DHG470B and ECA-2DM470B provide increased voltage rating (200 V vs. 160 V) while maintaining mechanical compatibility. ECA-2DHG470B includes AEC-Q200 automotive rating and extended operating temperature to 105°C. Both are Active products suitable for applications requiring higher voltage margin or extended temperature operation.

Nichicon alternatives provide extended lifetime specifications and broader operating temperature ranges. UCS2D470MHD1TO and UCY2D470MHD3TO are Active products with 10000-12000 hour lifetimes at 105°C, compared to 2000 hours at 85°C for the original part. UCY2D470MHD3TO and UCY2E470MHD3TO extend the lower operating temperature limit to -40°C.

UCA2C470MHD1TO and UCA2D470MHD1TO are classified as Not For New Designs and should not be selected for new applications. UVK2D470MHD1TO is similarly classified as Not For New Designs.

All substitute parts maintain the critical mechanical parameters: 47 µF capacitance, ±20% tolerance, radial can package, 0.197" (5.00 mm) lead spacing, 0.492" (12.50 mm) diameter, and through-hole mounting. Height variations (0.846" vs. 0.866" maximum) must be evaluated against PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can ECA-2CM470B be replaced with a 160 V rated substitute from another manufacturer?

A: Yes. UCA2C470MHD1TO from Nichicon meets all critical electrical and mechanical parameters at 160 V rating. However, UCA2C470MHD1TO is classified as Not For New Designs. For new applications, select an Active product such as UCS2D470MHD1TO or UCY2D470MHD3TO, which provide higher voltage ratings (200 V) and extended lifetime specifications while maintaining mechanical compatibility.

Q: What is the difference between ECA-2CM470B and ECA-2CM470?

A: Both parts are identical in electrical and mechanical specifications. The difference is packaging format: ECA-2CM470B is supplied in Tape & Box (TB) format, while ECA-2CM470 is supplied in Bulk format. Selection depends on procurement and assembly requirements.

Q: Can I use a 200 V rated capacitor in place of the 160 V ECA-2CM470B?

A: Yes. Panasonic ECA-2DHG470B, ECA-2DM470B, and Nichicon UCS2D470MHD1TO, UCY2D470MHD3TO, UVK2D470MHD1TO all provide 200 V rating with identical 47 µF capacitance and ±20% tolerance. Higher voltage rating provides additional safety margin in the circuit. All maintain the required mechanical parameters for direct PCB substitution.

Q: Are there height differences between substitute parts?

A: Yes. ECA-2CM470B, ECA-2DHG470B, ECA-2DM470B, and UVK2D470MHD1TO have maximum seated height of 0.866" (22.00 mm). Nichicon UCS series and UCY series parts have maximum seated height of 0.846" (21.50 mm). The 0.020" (0.50 mm) difference must be evaluated against PCB layout and clearance requirements.

Q: Which substitute parts are suitable for new designs?

A: Panasonic ECA-2DHG470B, ECA-2DM470B, and Nichicon UCS2D470MHD1TO, UCS2E470MHD1TO, UCY2D470MHD3TO, UCY2E470MHD3TO are all classified as Active product status and are suitable for new designs. Parts classified as Not For New Designs (UCA2C470MHD1TO, UCA2D470MHD1TO, UVK2D470MHD1TO) should not be selected for new applications.

Q: What is the advantage of selecting UCY2D470MHD3TO over ECA-2DM470B?

A: UCY2D470MHD3TO provides 12000 hour lifetime at 105°C compared to 2000 hours at 85°C for ECA-2DM470B. Operating temperature range extends to -40°C (vs. -25°C minimum). These enhancements provide improved reliability in applications with extended temperature operation or higher ripple current demands. Both maintain identical 47 µF, 200 V, ±20% specifications and mechanical compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. REACH status varies: Panasonic parts and Nichicon UCS series are REACH Unaffected. Nichicon UCY series parts are REACH Affected. Verify REACH compliance requirements for your specific application and supply chain.
