Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Littelfuse 031107.5M are determined by strict equivalence across the following critical parameters:

• Current Rating: 7.5 A
• Voltage Rating: 32 V AC / 32 V DC
• Fuse Type: Cartridge, Glass
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4"
• Size / Dimension: 0.250" Dia x 1.250" L (6.35mm x 31.75mm)
• Series: AGC
• Mounting Type: Requires Holder

All identified substitute parts maintain identical electrical ratings and mechanical dimensions. Packaging configuration differences (Bulk versus 5-pack card) do not affect electrical or mechanical compatibility. All substitute parts are manufactured by Littelfuse Inc. and maintain Active product status with ROHS3 compliance and REACH Unaffected designation.

Parameter Comparison

Engineering Selection Recommendations

All three parts—031107.5M, 0AGC07.5V, and 0AGC07.5VP—are direct electrical and mechanical equivalents. Selection between these parts is based on packaging requirements and inventory availability rather than technical performance differences.

For applications requiring individual fuses in bulk packaging, either 031107.5M or 0AGC07.5V are suitable selections. Both maintain identical specifications and Active product status with full ROHS3 compliance and REACH Unaffected certification.

For applications requiring pre-packaged quantities, 0AGC07.5VP provides the same electrical and mechanical performance in a 5-pack card configuration. This packaging option does not affect electrical compatibility or mechanical fit within standard 3AB and 3AG fuse holders.

All parts are manufactured by Littelfuse Inc. and carry equivalent regulatory compliance certifications. Selection should be based on procurement quantity requirements, packaging preferences, and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 0AGC07.5V be used as a direct replacement for 031107.5M?

A: Yes. Both parts are electrically and mechanically identical, with matching 7.5 A current rating, 32 V AC/DC voltage rating, and 0.250" Dia x 1.250" L dimensions. Both fit standard 3AB and 3AG fuse holders without modification.

Q: What is the difference between 0AGC07.5VP and the other two parts?

A: 0AGC07.5VP is electrically and mechanically identical to 031107.5M and 0AGC07.5V. The only difference is packaging: 0AGC07.5VP is supplied in a 5-pack card configuration, while the other two are supplied in bulk. This packaging difference does not affect electrical performance or mechanical compatibility.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts—031107.5M, 0AGC07.5V, and 0AGC07.5VP—are ROHS3 compliant and REACH unaffected.

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

A: Yes. All three parts are rated for 32 V AC and 32 V DC operation and are suitable for both circuit types within their rated voltage and current specifications.

Q: Do these fuses require a specific holder type?

A: Yes. All three parts require a fuse holder. They are compatible with 3AB and 3AG holder configurations designed for 1/4" x 1-1/4" cartridge fuses.
