Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCHURTER 0034.5208 is based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Current Rating: 125 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Breaking Capacity: 35 A (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)

All substitute parts listed below meet these parameters identically. The primary distinction between substitutes is manufacturer (Littelfuse Inc. vs. SCHURTER Inc.) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

All three Littelfuse substitute parts (0313.125HXP, 0313.125MXP, 0313.125VXP) are direct functional equivalents to the SCHURTER 0034.5208. Selection among these substitutes should be based on:

Product Status: All Littelfuse alternatives carry Active product status, ensuring long-term availability and supply chain continuity compared to the obsolete SCHURTER part.

Regulatory Compliance: Littelfuse substitutes include CE certification in addition to CSA and UL approvals, providing broader international compliance coverage.

Inventory Availability: Littelfuse 0313.125MXP offers the highest stock level (1,781 pcs), followed by 0313.125HXP (1,030 pcs) and 0313.125VXP (731 pcs).

Mechanical Compatibility: All substitutes maintain identical package dimensions and holder requirements (3AB, 3AG format), ensuring direct mechanical interchangeability in existing designs.

Frequently Asked Questions (FAQ)

Q: Can Littelfuse 0313.125HXP, 0313.125MXP, and 0313.125VXP be used interchangeably with SCHURTER 0034.5208?

A: Yes. All three Littelfuse parts match the SCHURTER 0034.5208 across all critical electrical parameters (125 mA current rating, 250 V AC voltage rating, slow-blow response, 35 A breaking capacity) and mechanical specifications (3AB/3AG package, 1/4" x 1-1/4" dimensions). They are direct substitutes.

Q: What is the difference between the three Littelfuse substitute parts?

A: The three Littelfuse parts (0313.125HXP, 0313.125MXP, 0313.125VXP) are electrically and mechanically identical. Differences exist only in internal manufacturing specifications (melting I²t values: 0.152 for all three) and inventory levels. Selection can be based on availability and supply chain preference.

Q: Will these substitutes work in existing SCHURTER 0034.5208 holders?

A: Yes. All substitute parts use the same 3AB/3AG package format with identical 1/4" x 1-1/4" dimensions, ensuring compatibility with existing fuse holders designed for the SCHURTER part.

Q: Are the Littelfuse substitutes RoHS compliant?

A: Yes. All three Littelfuse substitute parts are ROHS3 compliant, matching the compliance status of the SCHURTER 0034.5208.

Q: What certifications do the substitute parts carry?

A: Littelfuse substitutes carry CE, CSA, and UL certifications. The original SCHURTER part carries CSA and UL certifications. The additional CE certification on Littelfuse parts provides expanded international regulatory coverage.
