Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TR15R is determined by strict alignment of electrical and mechanical parameters. The primary substitute identified is the FRN-R-15 manufactured by Eaton - Bussmann Electrical Division. This substitution is valid based on the following matching criteria:

• Current Rating: Both parts rated at 15A
• Voltage Rating: Both parts rated at 250V AC (FRN-R-15 additionally supports 125V DC)
• Fuse Class: Both parts classified as RK5
• Form Factor: Both are cartridge-type fuses requiring a holder
• Response Time: Both are slow-blow fuses
• Regulatory Compliance: Both carry CE, CSA, and UL approvals
• Trade Classification: Both share identical HTSUS code 8536.10.0040

Parameter Comparison

Engineering Selection Recommendations

Both the TR15R and FRN-R-15 are Active status components with identical electrical ratings (15A, 250V AC) and RK5 classification, making them functionally equivalent for standard 250V AC applications. The TR15R maintains ROHS3 compliance, while the FRN-R-15 is RoHS non-compliant. Selection between these parts should be based on specific regulatory requirements: applications requiring RoHS3 compliance must use the TR15R, while applications without RoHS restrictions may use either part. Both components carry CE, CSA, and UL approvals, ensuring suitability for industrial and commercial electrical protection circuits. The FRN-R-15 offers extended DC voltage capability (125V DC) and specified breaking capacity ratings, which may be advantageous in mixed-voltage or high-fault-current environments.

Frequently Asked Questions (FAQ)

Q: Can the FRN-R-15 be used as a direct replacement for the TR15R in all applications?

A: The FRN-R-15 is electrically equivalent for 250V AC applications. However, RoHS compliance status differs: the TR15R is ROHS3 compliant while the FRN-R-15 is not. Applications subject to RoHS regulations must use the TR15R. Both parts require compatible cartridge fuse holders.

Q: What is the significance of RK5 classification for these fuses?

A: RK5 is a fuse class designation indicating specific performance characteristics including current-limiting capability and breaking capacity. Both the TR15R and FRN-R-15 share this classification, confirming their functional equivalence for overcurrent protection in industrial circuits.

Q: Are there packaging differences between these substitute parts?

A: Yes. The TR15R is supplied in Box packaging, while the FRN-R-15 is supplied in Bulk packaging. Both are cartridge-type fuses requiring a compatible holder for installation.

Q: Does the FRN-R-15's DC voltage rating affect its use as a substitute?

A: The FRN-R-15 supports both 250V AC and 125V DC operation, while the TR15R specification lists only 250V AC. This additional DC capability does not prevent substitution in AC-only applications; it simply provides extended functionality if DC protection is required.

Q: What approvals do these fuses carry?

A: Both the TR15R and FRN-R-15 carry CE, CSA, and UL approvals, confirming compliance with international electrical safety standards for industrial and commercial use.
