Substitute Part Grouping Explanation

Substitute parts for the 0311005.M are identified based on the following critical parameters that determine functional equivalence:

• Current Rating: 5 A (exact match required)
• Voltage Rating: 32 V AC and 32 V DC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Physical Dimensions: 0.250" Dia x 1.250" L / 6.35mm x 31.75mm (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Series: AGC (exact match required)
• Response Time: Fast Blow (exact match required)

All identified substitutes maintain identical electrical and mechanical specifications, ensuring direct interchangeability in applications requiring 5 A protection at 32 V AC/DC with fast-blow characteristics in standard 3AB/3AG holders.

Parameter Comparison

Engineering Selection Recommendations

All three parts—0311005.M, 0AGC005.V, and 0AGC005.VP—are active products from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements:

• 0311005.M: Bulk packaging, 1,116 units in stock
• 0AGC005.V: Bulk packaging, 954 units in stock
• 0AGC005.VP: 5-piece card packaging, 962 units in stock

All parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The choice between bulk and card packaging depends on application requirements and inventory management practices. No technical performance differences exist between these options.

Frequently Asked Questions (FAQ)

Q: Can 0AGC005.V and 0AGC005.VP be used interchangeably with 0311005.M?

A: Yes. All three parts share identical electrical ratings (5 A, 32 V AC/DC), fuse type (cartridge, glass), physical dimensions (0.250" Dia x 1.250" L), and package compatibility (3AB, 3AG holders). The only difference is packaging format: bulk versus 5-piece card.

Q: What is the difference between bulk and card packaging?

A: Bulk packaging (0311005.M, 0AGC005.V) provides loose fuses for high-volume applications. Card packaging (0AGC005.VP) provides five fuses mounted on a card, suitable for retail or smaller quantity requirements. Electrical and mechanical specifications are identical.

Q: Are these fuses compatible with 3AB and 3AG holders?

A: Yes. All three parts are designed for 3AB and 3AG fuse holders. The physical dimensions (0.250" Dia x 1.250" L) conform to standard 3AB/3AG specifications.

Q: What does "Fast Blow" response time mean?

A: Fast Blow indicates the fuse responds quickly to overcurrent conditions, providing rapid circuit protection. This characteristic is consistent across all three parts.

Q: Are all three parts compliant with current regulations?

A: Yes. All parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
