Polarization: Polar (required)

Mechanical Parameters (Secondary):

Package Type: Radial, Can (required)
Lead Spacing: 0.138" (4.60mm) (required for PCB compatibility)
Size / Diameter: 0.315" Dia (8.00mm) (required for board fit)
Mounting Type: Through Hole (required)

Compliance & Status:

RoHS3 Compliant (required)
Product Status: Active preferred for new applications; Not For New Designs acceptable for legacy support

Substitutes are grouped into two categories:

Direct Equivalents (Same Voltage Rating - 25V): UPJ1E151MPD, UPW1E151MPD, ELXY250ELL151MH12D, ELXZ250ELL151MF15D

Voltage Upgrades (35V Rating): 157KXM035M, ELXZ350ELL151MH12D, ELXZ350ELL151MH12S

Engineering Selection Recommendations

For Direct Replacement (25V Applications):

UPW1E151MPD offers the lowest impedance (117 mOhms) among Nichicon equivalents and maintains identical electrical specifications. ELXY250ELL151MH12D and ELXZ250ELL151MF15D are Active status alternatives from Chemi-Con with AEC-Q200 automotive certification. ELXZ250ELL151MF15D operates at reduced lifetime (2000 Hrs vs. 3000 Hrs @ 105°C) and features different lead spacing (0.098" vs. 0.138"), requiring PCB layout verification.

For Voltage Upgrade Applications (35V Rated):

157KXM035M from Cornell Dubilier provides higher voltage margin with Active product status. ELXZ350ELL151MH12D and ELXZ350ELL151MH12S from Chemi-Con both feature lower impedance (120 mOhms) and AEC-Q200 compliance. These 35V options are suitable where circuit design permits higher voltage ratings and improved reliability margin is required.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance. For automotive applications, prioritize parts with AEC-Q200 ratings: ELXY250ELL151MH12D, ELXZ250ELL151MF15D, ELXZ350ELL151MH12D, and ELXZ350ELL151MH12S.

Frequently Asked Questions (FAQ)

Q: Can UPJ1E151MPD replace UPM1E151MPD in automotive circuits?

A: UPJ1E151MPD matches all electrical parameters (150 µF, 25 V, ±20%, 3000 Hrs @ 105°C) and mechanical specifications. However, it lacks AEC-Q200 certification and is classified as "Not For New Designs." Use only where automotive qualification is not required.

Q: What is the difference between 25V and 35V rated substitutes?

A: 35V rated parts (157KXM035M, ELXZ350ELL151MH12D, ELXZ350ELL151MH12S) provide higher voltage margin and are electrically compatible in 25V circuits. They offer improved reliability but occupy similar or slightly larger physical space. Verify PCB layout compatibility before substitution.

Q: Does ELXZ250ELL151MF15D have different lead spacing?

A: Yes. ELXZ250ELL151MF15D uses 0.098" (2.50mm) lead spacing versus the standard 0.138" (4.60mm). This requires PCB footprint modification and is not a direct drop-in replacement.

Q: Which substitute has the lowest impedance?

A: UPW1E151MPD (117 mOhms) and ELXZ350ELL151MH12D/ELXZ350ELL151MH12S (120 mOhms) offer the lowest impedance values, beneficial for high-frequency ripple current applications.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance matching the original UPM1E151MPD specification.

Q: What is the height difference between substitutes?

A: Heights range from 0.453" (UPW1E151MPD) to 0.650" (ELXZ250ELL151MF15D). Verify clearance in your PCB assembly before selecting parts with maximum heights exceeding 0.531".
