Key Parameters

Substitute Part Grouping Explanation

Substitution for the UPW1E151MPD is determined by the following critical parameters:

• Capacitance: 150 µF (exact match required)
• Voltage Rating: 25 V minimum (higher voltage ratings are acceptable as upgrades)
• Tolerance: ±20% (standard tolerance for this category)
• Polarization: Polar (electrolytic capacitor type)
• Mounting Type: Through Hole (mechanical compatibility)
• Package Type: Radial, Can (physical form factor)
• Lead Spacing: 0.138" (4.60mm) or compatible spacing
• Operating Temperature: -55°C ~ 105°C (functional range)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Substitute parts are grouped into two categories:

Upgrade Substitutes: Parts with identical capacitance and tolerance but higher voltage ratings (35 V), providing enhanced voltage margin while maintaining mechanical and electrical compatibility.

Equivalent Substitutes: Parts from alternative manufacturers (Nichicon UPJ, UPM series and Chemi-Con LXY, LXZ series) with matching or comparable electrical specifications and physical dimensions, suitable for direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Specifications)

UPJ1E151MPD and UPM1E151MPD from Nichicon maintain identical capacitance, voltage, and lifetime specifications. UPM1E151MPD carries AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade components. Both parts are mechanically compatible with the original UPW1E151MPD footprint, though height variations (12.50mm and 13.00mm respectively versus 11.50mm) must be verified against PCB clearance constraints.

For Voltage Upgrade

UPW1V151MPD provides a direct upgrade path within the Nichicon UPW series, offering 35 V rating while maintaining identical physical dimensions and impedance characteristics. This substitution is appropriate when circuit design margins require higher voltage tolerance without mechanical redesign.

For Active Product Status

ELXY250ELL151MH12D and ELXZ250ELL151MF15D from Chemi-Con are both active products with AEC-Q200 certification. ELXY250ELL151MH12D maintains the same lead spacing and comparable height, making it the preferred alternative for applications requiring an actively manufactured component. ELXZ250ELL151MF15D features reduced lead spacing (2.50mm versus 4.60mm) and increased height (16.50mm), requiring PCB layout verification before implementation.

Compliance Considerations

All substitute parts maintain ROHS3 compliance. UPM1E151MPD and both Chemi-Con alternatives carry AEC-Q200 certification for automotive applications. Selection should align with application requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can UPW1V151MPD replace UPW1E151MPD in all applications?

A: UPW1V151MPD is electrically compatible as a direct upgrade, offering higher voltage rating (35 V versus 25 V) with identical capacitance, tolerance, and physical dimensions. Substitution is valid for any circuit designed for 25 V operation. No circuit modifications are required.

Q: What is the difference between Nichicon UPW, UPJ, and UPM series?

A: All three series share identical capacitance (150 µF) and voltage (25 V) specifications with 3000-hour lifetime at 105°C. UPM series includes AEC-Q200 automotive qualification. Physical dimensions vary slightly: UPW height is 11.50mm, UPJ is 12.50mm, and UPM is 13.00mm. Impedance also differs: UPW at 117 mOhms, UPJ at 260 mOhms, and UPM at 160 mOhms.

Q: Are Chemi-Con LXY and LXZ series direct replacements?

A: ELXY250ELL151MH12D is mechanically compatible with identical lead spacing (4.60mm) and comparable height (14.60mm). ELXZ250ELL151MF15D has different lead spacing (2.50mm) and greater height (16.50mm), requiring PCB layout verification. Both are AEC-Q200 certified and actively manufactured.

Q: Why does ELXZ250ELL151MF15D have reduced lifetime (2000 Hrs versus 3000 Hrs)?

A: ELXZ250ELL151MF15D is specified for 2000 hours at 105°C, compared to 3000 hours for other substitutes. This difference must be evaluated against application duty cycle and reliability requirements. For applications requiring 3000-hour minimum lifetime, ELXY250ELL151MH12D is the preferred Chemi-Con alternative.

Q: What is the impact of impedance variation among substitutes?

A: Impedance values range from 117 mOhms (UPW1E151MPD, UPW1V151MPD) to 260 mOhms (UPJ1E151MPD). Lower impedance provides better high-frequency performance and reduced ripple current effects. Selection should consider circuit frequency response requirements and ripple current specifications.

Q: Can I use these substitutes in automotive applications?

A: UPM1E151MPD, ELXY250ELL151MH12D, and ELXZ250ELL151MF15D carry AEC-Q200 certification for automotive use. UPW1E151MPD, UPW1V151MPD, and UPJ1E151MPD do not have automotive qualification and should not be used in automotive applications without design review.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the original UPW1E151MPD is in mature or end-of-life phase. For new designs, consider UPW1V151MPD (same series, higher voltage) or active alternatives such as ELXY250ELL151MH12D or ELXZ250ELL151MF15D from Chemi-Con.
