PCE-5-R Equivalent & Substitute Parts Reference

Part Overview

The PCE-5-R is a 5 A board mount fuse manufactured by Eaton - Electronics Division, rated for 125 V AC and 400 V DC operation. This through-hole radial fuse is designed for fast-blow response applications requiring CSA and UL approval. The part is currently active in production with 1017 pieces in stock. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design flexibility is required within compatible electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the PCE-5-R are classified into two categories based on electrical parameter compatibility:

Direct Equivalent (BK/PCE-5-R): This substitute maintains identical electrical specifications including 5 A current rating, 125 V AC / 400 V DC voltage ratings, fast-blow response, and breaking capacity. The part is manufactured by the same supplier (Eaton - Electronics Division) within the PC-Tron® series. Mechanical dimensions, mounting configuration, and approval certifications remain unchanged. This classification permits direct replacement without circuit redesign.

Similar Substitute (7100.1072.13): This substitute shares the 5 A current rating, fast-blow response, through-hole radial mounting, and board mount configuration. However, voltage ratings differ: 250 V AC / 250 V DC versus the primary part's 125 V AC / 400 V DC specification. The breaking capacity is specified as 63A (different from the primary part's 10kA AC / 4.2kA DC). Physical dimensions are larger (0.453" L x 0.197" W x 0.315" H versus 0.300" L x 0.095" W x 0.170" H). This part is manufactured by SCHURTER Inc. within the FRT 250F series and carries cURus approval. Selection of this substitute requires verification that circuit voltage requirements do not exceed 250 V AC or 250 V DC.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The BK/PCE-5-R substitute is suitable for applications requiring identical electrical performance and physical form factor. Both parts carry CSA and UL approval certifications and maintain ROHS3 compliance. Current inventory of 1425 pieces for BK/PCE-5-R provides supply continuity. Selection of this substitute does not require circuit modification.

For Alternative Sourcing: The 7100.1072.13 substitute from SCHURTER Inc. is applicable only in circuits where maximum operating voltage does not exceed 250 V AC or 250 V DC. This part carries cURus certification and maintains ROHS3 compliance. The larger physical dimensions (0.453" L x 0.197" W x 0.315" H) require verification of available board space. The different breaking capacity specification (63A versus 10kA AC / 4.2kA DC) and melting I²t value (7.2 versus 5) must be evaluated against circuit protection requirements. Current inventory of 1533 pieces provides adequate supply.

Frequently Asked Questions (FAQ)

Q: Can BK/PCE-5-R be used as a direct replacement for PCE-5-R?

A: Yes. BK/PCE-5-R maintains identical electrical ratings (5 A, 125 V AC, 400 V DC), response time (fast-blow), breaking capacity (10kA AC, 4.2kA DC), physical dimensions, and approval certifications (CSA, UL). No circuit modification is required.

Q: What are the voltage limitations when using 7100.1072.13?

A: The 7100.1072.13 is rated for 250 V AC and 250 V DC maximum. It cannot be used in circuits exceeding these voltage specifications. The primary PCE-5-R supports 125 V AC and 400 V DC, providing higher DC voltage capability.

Q: Are there physical space considerations when substituting with 7100.1072.13?

A: Yes. The 7100.1072.13 has larger dimensions (0.453" L x 0.197" W x 0.315" H) compared to PCE-5-R (0.300" L x 0.095" W x 0.170" H). Board layout verification is required before selection.

Q: Do all substitute parts meet the same regulatory approvals?

A: PCE-5-R and BK/PCE-5-R carry CSA and UL approvals. The 7100.1072.13 carries cURus approval. Application requirements determine which certification is necessary.

Q: What is the significance of the different melting I²t values?

A: PCE-5-R and BK/PCE-5-R have melting I²t of 5, while 7100.1072.13 has melting I²t of 7.2. This parameter affects thermal response characteristics. Circuit protection coordination must account for this difference when using 7100.1072.13.

Q: Can 7100.1072.13 be used in high DC voltage applications?

A: No. The 7100.1072.13 is rated for 250 V DC maximum, which is lower than the PCE-5-R's 400 V DC rating. Applications requiring 400 V DC operation must use PCE-5-R or BK/PCE-5-R.
