C310T-SC-5-R-TR2 Equivalent & Substitute Parts

Part Overview

The C310T-SC-5-R-TR2 is a ceramic cartridge fuse rated at 5A, 250VAC with slow-blow response characteristics. This through-hole mounted component is designed for circuit protection applications requiring reliable overcurrent interruption. The part is currently in active production status with full international approvals including CQC, cURus, KC, TUV, and VDE certification. Substitute parts are identified when packaging or inventory availability requires alternative sourcing while maintaining identical electrical and mechanical performance specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the C310T-SC-5-R-TR2 is determined by strict equivalence across the following critical parameters:

• Current Rating: 5 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Breaking Capacity @ Rated Voltage: 50 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Size / Dimension: 0.142" Dia x 0.394" L (3.60mm x 10.00mm) (exact match required)
• DC Cold Resistance: 7.3 mOhms (exact match required)
• Approval Agencies: CQC, cURus, KC, TUV, VDE (exact match required)

The C310T-SC-5-R-TR2 belongs to the C310T-SC series. Substitute parts within this series maintain identical electrical performance and mechanical compatibility. Packaging format differences (such as reel versus cut tape) do not affect functional equivalence when all other parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both the C310T-SC-5-R-TR2 and C310T-SC-5-R-TR1 are active production parts manufactured by Eaton - Electronics Division with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and inventory requirements rather than functional performance.

C310T-SC-5-R-TR2 is supplied in tape and reel format (TR2), suitable for automated assembly processes and high-volume production environments.

C310T-SC-5-R-TR1 is supplied in cut tape format (CT), suitable for manual assembly, prototyping, and lower-volume applications.

Both parts carry full international regulatory approvals (CQC, cURus, KC, TUV, VDE) and RoHS compliance certification. Both maintain identical breaking capacity, thermal performance, and resistance characteristics across the specified operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can C310T-SC-5-R-TR1 be used as a direct replacement for C310T-SC-5-R-TR2?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: TR2 is tape and reel, while TR1 is cut tape. This difference does not affect circuit protection performance or component functionality.

Q: What does the packaging designation (TR2 vs. TR1) mean?

A: TR2 indicates tape and reel packaging, typically used for automated pick-and-place assembly. TR1 indicates cut tape packaging, typically used for manual assembly or lower-volume applications. The fuse itself is identical in both cases.

Q: Are both parts RoHS compliant?

A: Yes. Both C310T-SC-5-R-TR2 and C310T-SC-5-R-TR1 are RoHS compliant and carry identical international certifications (CQC, cURus, KC, TUV, VDE).

Q: What is the breaking capacity of these fuses?

A: Both parts have a breaking capacity of 50 A at the rated voltage of 250 VAC.

Q: What is the operating temperature range?

A: Both parts operate reliably across the temperature range of -55°C to 125°C.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.142" diameter by 0.394" length (3.60mm x 10.00mm).

Q: What is the DC cold resistance specification?

A: Both parts have a DC cold resistance of 7.3 mOhms.

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

A: These are rated for 250 VAC. DC application capability is not specified in the provided parameters and should be verified against application requirements.
