157TXK160M Equivalent & Substitute Parts

Part Overview

The 157TXK160M is a 150 µF, 160 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the TXK series. This radial, through-hole component is designed for general-purpose applications with a rated lifetime of 5000 hours at 105°C. The part is currently active in production status with 885 pieces available in inventory.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements demand extended operational lifetime, or when alternative manufacturers' components meet identical electrical and mechanical specifications within the allowed tolerance parameters.

Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict equivalence across the following parameters:

Primary Equivalence Criteria:

• Capacitance value: 150 µF (exact match required)
• Voltage rating: 160 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Lead spacing: 0.295" (7.50 mm) (exact match required)
• Case diameter: 0.630" (16.00 mm) (exact match required)
• Operating temperature range: -25°C to 105°C (exact match required)

Secondary Compatibility Parameters:

• Height variation within mechanical tolerance
• Ripple current ratings (equal or greater acceptable)
• Lifetime at temperature (equal or greater acceptable)
• ESR values (when specified)

All substitute parts listed meet the primary equivalence criteria and are mechanically and electrically interchangeable with the 157TXK160M in through-hole PCB applications.

Engineering Selection Recommendations

157TXK160M (Cornell Dubilier / Illinois Capacitor)

Primary selection for new designs and applications requiring active product status. This part maintains current manufacturing support and is available in production quantities. ROHS3 compliance and REACH unaffected status confirm regulatory alignment for current applications.

UCA2C151MHD (Nichicon)

This substitute provides extended operational lifetime of 12000 hours at 105°C compared to the 5000-hour rating of the primary part. However, the product status is listed as obsolete, indicating discontinued manufacturing. This part is suitable for replacement applications where extended lifetime is required and existing inventory is available. ROHS3 compliance and REACH unaffected status are maintained. Height dimension is 0.020" (0.50 mm) shorter than the primary part, which remains within mechanical tolerance for standard through-hole PCB applications.

EEU-EB2C151 (Panasonic Electronic Components)

This substitute maintains identical electrical specifications and lifetime rating (5000 hours at 105°C) as the primary part. Product status is active, confirming current manufacturing availability. ROHS3 compliance and REACH unaffected status are confirmed. Height dimension matches the primary part exactly at 1.319" (33.50 mm). This part provides direct functional equivalence with active production support.

Frequently Asked Questions (FAQ)

Q: Can the UCA2C151MHD be used as a direct replacement for the 157TXK160M?

A: Yes. The UCA2C151MHD meets all primary equivalence criteria including capacitance, voltage rating, tolerance, polarization, mounting type, package type, lead spacing, case diameter, and operating temperature range. The 0.020" height difference is within mechanical tolerance for through-hole PCB applications. However, the obsolete product status indicates this part is no longer in active production.

Q: What is the difference between the EEU-EB2C151 and the 157TXK160M?

A: Both parts are electrically and mechanically equivalent. The EEU-EB2C151 is manufactured by Panasonic and maintains active product status, whereas the 157TXK160M is manufactured by Cornell Dubilier / Illinois Capacitor. Dimensions, electrical ratings, and compliance certifications are identical or equivalent.

Q: Why does the UCA2C151MHD have a longer lifetime rating?

A: The UCA2C151MHD is rated for 12000 hours at 105°C compared to 5000 hours for the 157TXK160M. This difference reflects different internal construction and materials used by Nichicon in the UCA series. Both parts meet the same electrical specifications and are mechanically interchangeable.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 157TXK160M, UCA2C151MHD, and EEU-EB2C151 are all ROHS3 compliant and REACH unaffected, confirming regulatory compliance for current applications.

Q: Does the height difference of the UCA2C151MHD affect PCB compatibility?

A: No. The UCA2C151MHD height of 1.299" (33.00 mm) is 0.020" (0.50 mm) shorter than the 157TXK160M at 1.319" (33.50 mm). This difference is within standard mechanical tolerance for through-hole radial capacitor applications and does not affect PCB layout or component clearance.

Q: Which substitute part should be selected for new designs?

A: The EEU-EB2C151 is recommended for new designs due to active product status and confirmed manufacturing availability. This part provides direct electrical and mechanical equivalence to the 157TXK160M with ongoing production support.

Q: Can these parts be used interchangeably in existing applications?

A: Yes. All three parts meet identical primary equivalence criteria and are mechanically and electrically interchangeable in through-hole PCB applications. Lead spacing, case diameter, and operating temperature ranges are identical across all three parts.
