Engineering Selection Recommendations

For Active Product Designs:

UCS2D100MPD1TD (Nichicon UCS series): Active product status with 8000-hour lifetime, superior ripple current handling, and extended operating temperature range (-40°C to 105°C). Mechanical compatibility confirmed with 0.689" maximum height.
ECA-2EHG100 (Panasonic upgrade): Active status with voltage margin increase to 250 V, maintaining identical mechanical footprint and thermal performance.

For Voltage Margin Applications:

UCY2G100MPD1TD (Nichicon UCY series): Active product with 400 V rating and 10000-hour lifetime. Provides maximum voltage headroom while maintaining mechanical compatibility.

Parts to Avoid for New Designs:

UCA2D100MPD1TD: Marked "Not For New Designs"
UPS2D100MPD1TD: Marked "Not For New Designs"
UPS2D100MPD: Obsolete product status
UPW2D100MPD: Obsolete product status

Compliance Verification: All recommended substitutes maintain ROHS3 compliance and EAR99 export classification matching the original part.

Frequently Asked Questions (FAQ)

Q: Can ECA-2EHG100 replace ECA-2DHG100B directly? A: Yes. Both parts share identical capacitance (10 µF), tolerance (±20%), mechanical dimensions, and thermal characteristics. ECA-2EHG100 provides a 250 V rating versus 200 V, offering voltage margin while maintaining Active product status and ROHS3 compliance.

Q: What is the height difference between ECA-2DHG100B and Nichicon substitutes? A: ECA-2DHG100B maximum height is 0.669" (17.00 mm). Nichicon UCA, UCS, UPS, and UCY series substitutes have maximum height of 0.689" (17.50 mm). This 0.020" (0.50 mm) difference is within typical through-hole PCB design tolerances and does not affect functional compatibility.

Q: Are Nichicon UCA2D100MPD1TD and UPS2D100MPD1TD suitable for new designs? A: Both parts carry "Not For New Designs" status. While electrically compatible, they should not be selected for new product development. UCS2D100MPD1TD (Active status) is the recommended Nichicon equivalent.

Q: What is the advantage of UCY2G100MPD1TD over direct voltage equivalents? A: UCY2G100MPD1TD provides 400 V rating (versus 200 V) and 10000-hour lifetime (versus 2000 hours). This upgrade path is suitable for applications requiring enhanced voltage margin and extended operational life, with maintained mechanical compatibility.

Q: Do all substitutes maintain the same lead spacing and diameter? A: Yes. All listed substitutes maintain 0.197" (5.00 mm) lead spacing and 0.394" (10.00 mm) diameter, ensuring PCB footprint compatibility. Height variation is limited to 0.020" (0.50 mm) maximum.

Q: What packaging formats are available? A: ECA-2DHG100B is supplied in Tape & Box format. Substitutes are available in Bulk (ECA-2EHG100, UPS2D100MPD) or Cut Tape (UCA2D100MPD1TD, UCS2D100MPD1TD, UPS2D100MPD1TD, UCY2G100MPD1TD) formats. Verify packaging requirements for procurement and assembly processes.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitutes maintain ROHS3 compliance and EAR99 export classification, matching the regulatory status of ECA-2DHG100B.
