Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TRS10R is determined by the following critical parameters:

• Current Rating: 10A (exact match required)
• Voltage Rating: 600V AC minimum (300V DC acceptable)
• Response Time: Time Delay (TD) or Slow Blow characteristic
• Physical Form Factor: Cartridge fuse compatible with standard holders
• Electrical Class: RK5 or equivalent protection class

The FRS-R-10 manufactured by Eaton - Bussmann Electrical Division meets these substitution criteria. Both parts share identical current and voltage ratings, equivalent response time characteristics, and compatible electrical protection classes. The FRS-R-10 is rated for 600 VAC / 300 VDC operation with a Slow Blow response time, making it functionally equivalent to the TRS10R for applications requiring time-delay fuse protection.

Parameter Comparison

Engineering Selection Recommendations

The FRS-R-10 is an active, production-status component with RoHS compliance and multi-agency certifications (CE, CSA, UL), providing enhanced regulatory alignment compared to the TRS10R. Both parts are classified under the same HTSUS code and ECCN designation, confirming their functional equivalence for electrical protection applications.

Selection between these parts should be based on:

• Regulatory compliance requirements: FRS-R-10 offers RoHS compliance advantage
• Certification requirements: FRS-R-10 carries CE, CSA, and UL approvals
• Supply availability: Both parts maintain active inventory status
• Physical mounting compatibility: Both are cartridge-type fuses requiring standard holders

Frequently Asked Questions (FAQ)

Q: Can the FRS-R-10 directly replace the TRS10R in existing installations?

A: Yes. Both parts share identical 10A current ratings and 600V AC voltage ratings with equivalent Slow Blow / Time Delay response characteristics. The FRS-R-10 requires a standard cartridge fuse holder, consistent with TRS10R mounting requirements.

Q: What is the significance of the RoHS compliance difference?

A: The FRS-R-10 is RoHS compliant while the TRS10R is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the FRS-R-10 is the appropriate selection.

Q: Are there voltage rating differences between these parts?

A: The TRS10R is rated for 600V. The FRS-R-10 is rated for 600 VAC / 300 VDC. Both meet or exceed the 600V AC requirement, making them electrically compatible.

Q: What does the RK5 class designation mean for the FRS-R-10?

A: RK5 is an electrical protection class indicating the fuse's breaking capacity and response characteristics. This class is standard for industrial cartridge fuses and confirms the FRS-R-10's suitability for general electrical protection applications.

Q: Does packaging type affect substitution compatibility?

A: The TRS10R is supplied in Box packaging while the FRS-R-10 is supplied in Bulk packaging. Packaging affects procurement and handling but does not impact electrical or mechanical compatibility. Both parts function identically in the application.
