Littelfuse 0311025.M Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0311025.M is a 25 A, 32 V AC/DC glass cartridge fuse designed for applications requiring reliable overcurrent protection in compact form factors. This fuse operates in the AGC series and requires a compatible holder (3AB, 3AG, 1/4" x 1-1/4"). The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when identical electrical ratings, mechanical dimensions, and compliance certifications are maintained across alternative packaging configurations or manufacturer offerings.

Substitute Part Grouping Explanation

Substitution eligibility for the 0311025.M is determined by strict equivalence across the following critical parameters:

• Current Rating: 25 A (exact match required)
• Voltage Rating: 32 V AC and 32 V DC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Series: AGC (exact match required)
• Physical Dimensions: 0.250" Dia x 1.250" L (exact match required)
• Holder Compatibility: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Compliance: RoHS3 Compliant, REACH Unaffected (exact match required)

The identified substitute part 0AGC025.VP maintains identical electrical and mechanical specifications. The primary distinction is packaging configuration: the main part is supplied in Bulk packaging, while the substitute is supplied as a 5-pack in cardboard (5PK CRD). Both parts are manufactured by Littelfuse Inc. and carry Active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the 0311025.M and 0AGC025.VP are Active status products with identical electrical performance and mechanical compatibility. Selection between these parts should be based on packaging requirements and inventory management:

• 0311025.M: Suitable for high-volume applications requiring bulk packaging and individual unit procurement.
• 0AGC025.VP: Suitable for applications where 5-unit quantities in cardboard packaging align with assembly or stocking procedures.

Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance across EU and international markets. Interchangeability is confirmed at the functional and mechanical level, with no performance degradation when substituting between these part numbers in identical circuit applications.

Frequently Asked Questions (FAQ)

Q: Can 0AGC025.VP be used as a direct replacement for 0311025.M in production assemblies?

A: Yes. Both parts are electrically and mechanically identical, with matching 25 A, 32 V AC/DC ratings, AGC series designation, and 3AB/3AG holder compatibility. The only difference is packaging format (Bulk vs. 5PK CRD).

Q: Are there any compatibility issues with existing fuse holders?

A: No. Both parts share identical physical dimensions (0.250" Dia x 1.250" L) and require the same holder types (3AB, 3AG, 1/4" x 1-1/4"). Direct mechanical and electrical interchangeability is confirmed.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both 0311025.M and 0AGC025.VP are RoHS3 Compliant and REACH Unaffected, meeting identical compliance standards for EU and international applications.

Q: What is the primary reason to choose one part over the other?

A: Selection is driven by packaging needs. Choose 0311025.M for bulk procurement of individual units. Choose 0AGC025.VP when 5-unit quantities in cardboard packaging match your supply chain or assembly workflow.

Q: Are there any performance differences between these parts?

A: No. Both parts carry identical electrical ratings (25 A, 32 V AC/DC), fuse response characteristics, and mechanical specifications. Performance is equivalent across all operating conditions within rated parameters.
