Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the C310T-SC-6-3-R-TR2 are qualified based on the following critical parameters:

Electrical Equivalence Criteria:

• Current Rating: 6.3 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 63 A (exact match required)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Size / Dimension: 0.142" Dia x 0.394" L / 3.60mm x 10.00mm (exact match required)

Environmental & Compliance Criteria:

• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: RoHS Compliant or equivalent (acceptable)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part in circuit applications.

Engineering Selection Recommendations

C310T-SC-6-3-R-TR1 (Eaton - Electronics Division)

This substitute maintains identical electrical and mechanical specifications to the main part. Both are manufactured by Eaton - Electronics Division within the same C310T-SC series. The primary difference is packaging format: C310T-SC-6-3-R-TR1 is supplied in Cut Tape (CT) format versus the main part's Tape Reel (TR2) format. Both parts carry Active product status and RoHS Compliance certification. This substitute is suitable for applications where packaging format does not constrain procurement or assembly processes.

087706.3MRET1P (Littelfuse Inc.)

This substitute is manufactured by Littelfuse Inc. and meets all critical electrical and mechanical parameters. The part is supplied in Cut Tape (CT) packaging. DC Cold Resistance is 8.7 mOhms compared to 7.1 mOhms in the main part, representing a 22.5% variance within acceptable tolerance for ceramic cartridge fuse applications. The part carries ROHS3 Compliance and holds Active product status. Approval agencies include cULus and VDE certifications. This substitute is suitable for applications requiring cross-manufacturer sourcing or where Littelfuse supply chain availability is preferred.

Frequently Asked Questions (FAQ)

Q: Can C310T-SC-6-3-R-TR1 be used as a direct replacement for C310T-SC-6-3-R-TR2?

A: Yes. Both parts are electrically and mechanically equivalent with identical current ratings (6.3 A), voltage ratings (250 V AC), response characteristics (Slow Blow), physical dimensions (0.142" Dia x 0.394" L), and operating temperature ranges (-55°C ~ 125°C). The difference in packaging format (Cut Tape versus Tape Reel) does not affect functional performance in circuit applications.

Q: What is the difference between the Eaton and Littelfuse substitute options?

A: Both substitutes meet the core electrical and mechanical requirements. The primary differences are manufacturer origin and DC Cold Resistance specification. Littelfuse 087706.3MRET1P exhibits 8.7 mOhms resistance versus 7.1 mOhms in the Eaton parts. Both values are within acceptable operating parameters for ceramic cartridge fuses. Selection between manufacturers depends on supply chain preferences and procurement requirements.

Q: Are there packaging format considerations when selecting a substitute?

A: Yes. The main part C310T-SC-6-3-R-TR2 is supplied in Tape Reel (TR2) format, while both substitutes are supplied in Cut Tape (CT) format. Tape Reel packaging is typically used for high-volume automated assembly processes, while Cut Tape is suitable for lower-volume or manual assembly operations. Verify that your assembly equipment and processes are compatible with the selected packaging format.

Q: Do all substitute parts carry the same certifications?

A: The main part and C310T-SC-6-3-R-TR1 both carry CQC, cURus, KC, TUV, and VDE approvals. The Littelfuse substitute 087706.3MRET1P carries cULus and VDE approvals. All three parts are RoHS Compliant (RoHS or ROHS3). Verify that the certification profile of your selected substitute meets your application's regulatory requirements.

Q: Can these fuses be used in both AC and DC circuits?

A: All three parts are rated for 250 V AC/DC operation. They are suitable for both alternating current and direct current circuit protection applications within the specified voltage and current parameters.
