Equivalent & Substitute Parts for 157KXM050M

Part Overview

The 157KXM050M is a 150 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as Active product status and is designed for general-purpose applications requiring through-hole mounting. The part is ROHS3 compliant and suitable for operating environments ranging from -55°C to 105°C.

Substitute parts are identified when equivalent electrical and mechanical parameters are available from alternative manufacturers. Substitution becomes necessary due to inventory availability, supply chain considerations, or design flexibility requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 157KXM050M is determined by the following critical parameters:

Electrical Parameters:

• Capacitance value: 150 µF (exact match required)
• Voltage rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Package type: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Diameter: 0.394" (10.00 mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (required for substitution)

The substitute part UHE1H151MPD from Nichicon meets all critical electrical and mechanical parameters. Variations in height, ESR, ripple current ratings, and lifetime specifications do not disqualify substitution when the above parameters are matched.

Engineering Selection Recommendations

Primary Part: 157KXM050M

The 157KXM050M maintains Active product status and is recommended for new designs when available. This part provides the specified operating temperature range of -55°C to 105°C and is suitable for applications requiring extended low-temperature operation.

Substitute Part: UHE1H151MPD

The UHE1H151MPD from Nichicon is electrically and mechanically compatible with the 157KXM050M. This substitute carries Not For New Designs status, indicating it is available for replacement and legacy applications but not recommended for new product development.

Selection Criteria:

• Use 157KXM050M for new designs and applications requiring the full -55°C to 105°C operating range.
• Use UHE1H151MPD for replacement applications, legacy system maintenance, or when supply of the primary part is unavailable.
• The UHE1H151MPD provides extended lifetime (7000 Hrs @ 105°C versus 4000 Hrs @ 105°C) and lower impedance (120 mOhms versus 180 mOhms), which may provide performance benefits in specific applications.
• The reduced height of UHE1H151MPD (0.492" versus 0.551") allows for tighter PCB layout constraints without functional compromise.
• Both parts are ROHS3 compliant and suitable for regulated environments.

Frequently Asked Questions (FAQ)

Q: Can UHE1H151MPD be used as a direct replacement for 157KXM050M?

A: Yes. The UHE1H151MPD meets all critical electrical parameters (150 µF, 50 V, ±20% tolerance) and mechanical specifications (radial can package, 5.00 mm lead spacing, 10.00 mm diameter, through-hole mounting). Both parts are ROHS3 compliant. The substitute is physically shorter (12.50 mm versus 14.00 mm), which is compatible with PCB layouts designed for the original part.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Operating temperature range—157KXM050M operates from -55°C to 105°C, while UHE1H151MPD operates from -40°C to 105°C; (2) Lifetime—UHE1H151MPD provides 7000 hours at 105°C compared to 4000 hours for 157KXM050M; (3) Impedance—UHE1H151MPD has lower impedance (120 mOhms versus 180 mOhms); (4) Physical height—UHE1H151MPD is 0.492" versus 0.551" for 157KXM050M; (5) Product status—157KXM050M is Active while UHE1H151MPD is Not For New Designs.

Q: Is the height difference between these parts significant?

A: The UHE1H151MPD is 0.059" (1.50 mm) shorter than the 157KXM050M. This difference is generally not significant for most through-hole applications and allows the substitute to fit within PCB layouts designed for the original part. Verify clearance in applications with height-constrained mounting areas.

Q: Are both parts suitable for applications requiring -55°C operation?

A: No. The 157KXM050M is rated for -55°C to 105°C operation, while the UHE1H151MPD is rated for -40°C to 105°C. For applications requiring operation below -40°C, the 157KXM050M must be used.

Q: What is the significance of the "Not For New Designs" status on UHE1H151MPD?

A: This status indicates that Nichicon does not recommend the UHE1H151MPD for incorporation into new product designs. It remains available for replacement, repair, and legacy system support. For new designs, the 157KXM050M (Active status) is the appropriate choice.

Q: Do both parts have the same RoHS compliance?

A: Yes. Both 157KXM050M and UHE1H151MPD are ROHS3 compliant, meeting current regulatory requirements for restricted substances in electrical and electronic equipment.
