Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The 107BPS025M and 25NXA100MEFC8X11.5 are recommended as primary substitutes due to their Active product status. Both maintain identical mechanical compatibility and exceed the original voltage specification at 25 V, providing design margin for circuit applications. The 107BPS025M offers extended lifetime (2000 Hrs @ 85°C) compared to the original specification. The 25NXA100MEFC8X11.5 provides extended operating temperature range (-55°C ~ 105°C) and higher temperature lifetime rating (1000 Hrs @ 105°C).

Secondary Substitutes (Not For New Designs):

The UEP1C101MPD and UEP1E101MPD are Nichicon alternatives within the same manufacturer family. Both are classified as "Not For New Designs" but remain available in inventory. The UEP1C101MPD provides 16 V rating with extended temperature range, while the UEP1E101MPD offers 25 V rating with the widest operating temperature specification (-55°C ~ 105°C).

All substitute parts maintain ROHS3 compliance and identical lead spacing and package dimensions, ensuring direct PCB compatibility with the original UES0J101MPM design.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute?

A: Yes. All substitute parts listed feature voltage ratings of 16 V or 25 V, which exceed the original 6.3 V specification. Higher voltage ratings are electrically compatible and provide additional design margin without affecting circuit performance.

Q: Are the physical dimensions identical across all substitutes?

A: Nearly all substitutes maintain identical dimensions (0.315" diameter, 0.512" maximum height) with one exception: the 107BPS025M has a maximum height of 0.531" (14.60 mm), which is 0.019" taller. Verify PCB clearance before selection if space is constrained.

Q: What is the difference between Active and Not For New Designs status?

A: Active products are currently manufactured and supported by the supplier. "Not For New Designs" indicates end-of-life status with limited future availability. For new designs or long-term production, select 107BPS025M or 25NXA100MEFC8X11.5.

Q: Do all substitutes have the same lead spacing?

A: Yes. All substitute parts maintain 0.138" (4.60 mm) lead spacing, ensuring direct compatibility with PCB footprints designed for the UES0J101MPM.

Q: Which substitute offers the best lifetime rating?

A: The 107BPS025M provides 2000 Hrs @ 85°C, double the original specification of 1000 Hrs @ 85°C. The UEP1C101MPD, UEP1E101MPD, and 25NXA100MEFC8X11.5 all provide 1000 Hrs @ 105°C, which represents higher temperature operation compared to the original.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 Compliant, matching the compliance status of the original UES0J101MPM.
