UHM1C152MPD Equivalent & Substitute Parts

Part Overview

The UHM1C152MPD is a 1500 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, indicating it is no longer in active production. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary for ongoing design support, maintenance, and new production requirements. Substitute parts maintain the core electrical specifications (capacitance, voltage rating, tolerance, and polarization) while offering improved reliability metrics, extended operational lifetimes, and compliance with current regulatory standards.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Capacitance: Must be 1500 µF (no tolerance variation)
Voltage Rating: Must be 16 V (no derating)
Tolerance: Must be ±20%
Polarization: Must be Polar
Package Type: Must be Radial, Can
Mounting Type: Must be Through Hole
Operating Temperature Range: Must support -40°C ~ 105°C
Lead Spacing: Must be 0.197" (5.00mm) for direct PCB compatibility
Physical Dimensions: Size and height must accommodate existing PCB layouts

Substitute parts are grouped into two categories: Nichicon series alternatives (UHD, UHE, UHV) offering extended lifetime ratings, and Panasonic Electronic Components alternatives (EEU-FM, EEU-FR series) providing active product status with equivalent or superior performance characteristics.

Engineering Selection Recommendations

Direct Replacement (Preferred for Maintenance)

EEU-FR1C152 and EEU-FR1C152B are the primary recommended substitutes. Both are manufactured by Panasonic Electronic Components with Active product status, ensuring long-term availability and supply chain stability. These parts maintain identical lead spacing (0.197", 5.00mm), core diameter (0.394", 10.00mm), and height (0.866", 22.00mm) as the original UHM1C152MPD, enabling direct PCB substitution without layout modifications. The 10000 Hrs @ 105°C lifetime rating provides extended operational reliability compared to the original 2000 Hrs specification. Both EEU-FR variants are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Alternative Nichicon Options (Extended Lifetime)

UHV1C152MPD offers a Nichicon alternative with matching lead spacing and core diameter. It provides 6000 Hrs @ 105°C lifetime with 19 mOhms impedance, representing a 3x improvement over the original part. However, height is 0.866" (22.00mm) versus the original 0.787" (20.00mm), requiring PCB layout verification. This part carries Not For New Designs status.

UHE1C152MHD6 provides 10000 Hrs @ 105°C lifetime with matching lead spacing (0.197", 5.00mm) and height (0.787", 20.00mm) to the original. However, the core diameter is 0.492" (12.50mm) versus 0.394" (10.00mm), requiring physical space verification on the PCB. This part also carries Not For New Designs status.

Panasonic FM Series (Compact Footprint)

EEU-FM1C152 and EEU-FM1C152B provide Active product status with 5000 Hrs @ 105°C lifetime. These parts have a larger core diameter (0.492", 12.50mm) and matching height (0.866", 22.00mm), requiring PCB layout assessment. The 18 mOhms impedance is superior to the original 13 mOhms specification.

Layout Constraint Considerations

For applications with strict PCB space constraints matching the original 0.394" (10.00mm) core diameter and 0.787" (20.00mm) height, EEU-FR1C152 or EEU-FR1C152B are the only viable substitutes. All other alternatives require either increased core diameter or height accommodation.

Frequently Asked Questions (FAQ)

Q: Can UHE1C152MHD3 be used as a direct replacement for UHM1C152MPD?

A: UHE1C152MHD3 meets all electrical specifications (1500 µF, 16 V, ±20%, Polar) but has different physical dimensions. The lead spacing is 0.295" (7.50mm) versus the original 0.197" (5.00mm), and the core diameter is 0.630" (16.00mm) versus 0.394" (10.00mm). PCB layout modification is required. This part is Not For New Designs.

Q: What is the difference between EEU-FR1C152 and EEU-FR1C152B?

A: Both parts are electrically and mechanically identical. The difference is packaging: EEU-FR1C152 is supplied in Bulk packaging, while EEU-FR1C152B is supplied in Cut Tape (CT) packaging. Selection depends on procurement and assembly requirements.

Q: Why is EEU-FR1C152L taller than other substitutes?

A: EEU-FR1C152L has a height of 1.063" (27.00mm) versus 0.866" (22.00mm) for standard EEU-FR variants. This increased height accommodates a different internal construction that provides 18 mOhms impedance (lower than standard FR variants at 20 mOhms) while maintaining 10000 Hrs @ 105°C lifetime. Use only if PCB clearance permits.

Q: Are all substitute parts RoHS compliant?

A: All Panasonic EEU-FM and EEU-FR series parts are ROHS3 Compliant. Nichicon UHD, UHE, and UHV series parts are also ROHS3 Compliant. The original UHM1C152MPD does not specify RoHS status.

Q: Which substitute offers the best impedance performance?

A: EEU-FM1C152, EEU-FM1C152B, and EEU-FR1C152L all provide 18 mOhms impedance, which is superior to the original UHM1C152MPD at 13 mOhms. EEU-FR1C152 and EEU-FR1C152B provide 20 mOhms. Lower impedance values indicate better high-frequency performance characteristics.

Q: Can I use UHE1C152MPD if my PCB has height constraints?

A: UHE1C152MPD has a height of 1.240" (31.50mm), which is significantly taller than the original 0.787" (20.00mm). This part is suitable only for applications with adequate vertical clearance. It is Not For New Designs.

Q: What is the advantage of the 10000 Hrs @ 105°C lifetime rating?

A: The original UHM1C152MPD is rated for 2000 Hrs @ 105°C. Substitute parts with 10000 Hrs @ 105°C (EEU-FR series, UHE series) provide 5x longer operational life under identical thermal conditions, improving system reliability and reducing field failure risk over extended service periods.

Q: Are there inventory considerations for substitute selection?

A: Panasonic EEU-FM1C152 has the highest inventory availability at 1,000,100 pieces. Panasonic EEU-FR1C152B has 3,636 pieces available. Nichicon alternatives have lower inventory levels (1,277 to 5,011 pieces). For high-volume production, Panasonic options provide superior supply chain assurance.
