Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0312010.MXP are qualified based on the following critical parameters:

• Current Rating: 10 A (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Mounting Type: Requires Holder (exact match required)

All identified substitutes maintain these core electrical and mechanical specifications. Variations in breaking capacity, melting I²t, DC cold resistance, and operating temperature ranges are noted but do not disqualify substitution eligibility when other parameters align.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain identical electrical ratings (10 A, 250 V AC), fuse type (cartridge, glass), response characteristic (fast blow), and mechanical package specification (3AB/3AG, 1/4" x 1-1/4"). Selection among active-status alternatives should prioritize compliance with application-specific regulatory requirements:

• Littelfuse 0312010.HXP: Direct manufacturer equivalent with identical specifications and certifications (CE, CSA, KC, PSE, UL).
• Bel Fuse 3AG 10-R: Active status with CE, CSA, cURus, and PSE certifications. Dimensional tolerance of 0.002" in length is within mechanical compatibility range.
• Eaton AGC-10-R, BK/AGC-10-R, BK/AGC-10RX: Active status alternatives with CSA and UL certifications. All three variants share identical electrical and mechanical specifications.
• SCHURTER 0001.1034: Obsolete product status. Operating temperature range (-40°C ~ 85°C) is narrower than primary alternatives. Selection not recommended for new designs.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the 0312010.MXP?

A: Yes, all active-status parts listed (0312010.HXP, 3AG 10-R, AGC-10-R, BK/AGC-10-R, BK/AGC-10RX) are electrically and mechanically equivalent. They share identical current ratings (10 A), voltage ratings (250 V AC), response characteristics (fast blow), and package specifications (3AB/3AG, 1/4" x 1-1/4"). Selection should be based on regulatory certification requirements for your application.

Q: What is the difference between the Littelfuse 0312010.MXP and 0312010.HXP?

A: Both parts are manufactured by Littelfuse Inc. and share identical electrical specifications, certifications, and mechanical dimensions. The primary difference is inventory availability (0312010.MXP: 16,866 units; 0312010.HXP: 3,603 units).

Q: Why is the SCHURTER 0001.1034 listed as a substitute if it is obsolete?

A: The SCHURTER 0001.1034 meets the core electrical and mechanical substitution criteria (10 A, 250 V AC, fast blow, 3AB/3AG package). However, its obsolete product status and narrower operating temperature range (-40°C ~ 85°C versus -55°C ~ 125°C) make it unsuitable for new designs or applications requiring extended temperature performance.

Q: Are there dimensional differences between these fuses?

A: Nominal dimensions are 0.250" diameter x 1.250" length (6.35mm x 31.75mm). The Bel Fuse 3AG 10-R and SCHURTER 0001.1034 have a length specification of 1.252" (31.80mm), representing a 0.002" tolerance variation. This difference is within standard mechanical compatibility for 3AB/3AG holder applications.

Q: Which certifications should I prioritize for my application?

A: Certification requirements depend on your end-use application and regional standards. The 0312010.MXP and 0312010.HXP carry the broadest certification coverage (CE, CSA, KC, PSE, UL). If your application requires specific certifications, cross-reference the approval agency list for each substitute part against your regulatory requirements.

Q: What is the difference between AGC-10-R, BK/AGC-10-R, and BK/AGC-10RX?

A: All three are manufactured by Eaton - Electronics Division and share identical electrical specifications, certifications (CSA, UL), and mechanical dimensions. The designations reflect different product variants within the AGC series. Selection among these three should be based on availability and internal part numbering conventions within your supply chain.
