Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Capacitance value must equal 10 µF
Tolerance must equal ±20%
Voltage rating must be equal to or greater than 200 V
Lead spacing must equal 0.197" (5.00mm)
Case diameter must equal 0.394" (10.00mm)
Mounting type must be Through Hole, Radial
Polarization must be Polar

Three substitute parts meet these criteria:

UVR2D100MPD (Nichicon UVR series): Identical voltage rating and mechanical dimensions; different packaging (Bulk vs. Cut Tape)
UVK2E100MPD1TD (Nichicon UVK series): Higher voltage rating (250 V); identical mechanical dimensions; product status is Not For New Designs
UVC2G100MPD1TD (Nichicon UVC series): Higher voltage rating (400 V); identical mechanical dimensions; enhanced temperature performance (2000 Hrs @ 105°C)

Engineering Selection Recommendations

UVR2D100MPD (Nichicon UVR): This part provides direct electrical equivalence with identical voltage and temperature ratings. However, it is classified as Not For New Designs and is supplied in Bulk packaging rather than Cut Tape. Selection of this part is appropriate only for replacement or legacy system applications where the original specification must be maintained.

UVK2E100MPD1TD (Nichicon UVK): This part offers a 250 V voltage rating, providing 25% voltage margin above the original specification. It maintains identical mechanical dimensions and Cut Tape packaging. However, it is classified as Not For New Designs and should not be selected for new product development.

UVC2G100MPD1TD (Nichicon UVC): This part is the preferred substitute for new designs. It provides a 400 V voltage rating (100% margin above the original specification), extended operating temperature range (-40°C ~ 105°C), and enhanced lifetime rating (2000 Hrs @ 105°C). It is classified as Active and supplied in Cut Tape packaging. The increased seated height (0.551" vs. 0.531") must be verified against PCB clearance constraints.

Frequently Asked Questions (FAQ)

Q: Can UVR2D100MPD be used as a direct replacement for ECA-2DM100B?

A: Yes, UVR2D100MPD provides electrical equivalence with identical capacitance, voltage rating, and temperature performance. However, it is classified as Not For New Designs and is supplied in Bulk packaging. Mechanical compatibility is confirmed through identical lead spacing and case diameter.

Q: What is the advantage of UVC2G100MPD1TD over the original part?

A: UVC2G100MPD1TD provides a 400 V voltage rating compared to the original 200 V rating, offering enhanced voltage margin. It also supports higher operating temperatures (up to 105°C) and is classified as Active for new designs. The increased seated height (0.551" vs. 0.531") requires PCB clearance verification.

Q: Why is UVK2E100MPD1TD marked as Not For New Designs?

A: UVK2E100MPD1TD is classified as Not For New Designs by the manufacturer. While it meets all mechanical and electrical substitution criteria with a 250 V rating, it should be used only for legacy system maintenance or replacement applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all substitute parts listed are ROHS3 compliant, matching the compliance status of the original ECA-2DM100B.

Q: Does packaging type affect electrical performance?

A: No. Packaging type (Cut Tape vs. Bulk) does not affect electrical performance. It affects only handling, storage, and procurement logistics. UVR2D100MPD in Bulk packaging is electrically equivalent to the Cut Tape version.

Q: What is the maximum seated height difference among substitute parts?

A: UVC2G100MPD1TD has a maximum seated height of 0.551" (14.00mm), compared to 0.531" (14.60mm) for the original part. This 0.020" (0.50mm) difference must be evaluated against PCB layout constraints and component clearance requirements.
