Littelfuse 0314010.H Ceramic Fuse 10A 250VAC 125VDC Equivalent & Substitute Parts

Part Overview

The Littelfuse 0314010.H is a 10 A ceramic cartridge fuse rated for 250 V AC and 125 V DC operation. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs. The fuse is designed for fast-blow response in applications requiring 3AB/3AG holder compatibility with dimensions of 0.250" diameter by 1.250" length (6.35mm x 31.75mm).

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0314010.H is determined by strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Current Rating: 10 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 125 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Substitute Categories:

Direct Littelfuse Manufacturer Equivalents: Parts 0314010.HXP, 0314010.MXANP, 0314010.MXP, and 0314010.VXP are direct parametric equivalents from Littelfuse Inc., Series 314. All maintain identical electrical specifications and mechanical dimensions. These parts differ only in packaging format (Bulk) and compliance certifications.

Cross-Manufacturer Alternatives: Parts BK/ABC-B-10 (Eaton - Electronics Division) and BP/ABC-10 (Eaton - Bussmann Electrical Division) are functionally equivalent ceramic cartridge fuses meeting the same electrical and mechanical requirements. These parts are from the ABC series and maintain compatibility with 3AB/3AG holders.

Parameter Comparison

Engineering Selection Recommendations

Littelfuse Direct Equivalents (0314010.HXP, 0314010.MXANP, 0314010.MXP, 0314010.VXP):

These parts are preferred for direct replacement of the obsolete 0314010.H. All four maintain identical electrical and mechanical specifications with active product status. Selection among these four should be based on:

• Packaging availability and supply chain requirements
• Compliance certifications needed for the application (CE, K-MARK, PSE, UL, CSA)
• RoHS3 compliance requirement (all four are ROHS3 Compliant)
• REACH status (all four are REACH Unaffected)

Eaton Cross-Manufacturer Alternatives (BK/ABC-B-10, BP/ABC-10):

These parts provide functional equivalence with the same current, voltage, and mechanical specifications. Selection of Eaton alternatives should account for:

• Lower breaking capacity at rated AC voltage (200A AC versus 750A AC for Littelfuse parts)
• Slightly different melting I²t values (215.6 and 208.8 versus 206 for Littelfuse)
• Marginally different DC cold resistance values
• RoHS compliance status (BK/ABC-B-10 is non-compliant; BP/ABC-10 is compliant)
• Certification requirements (both hold CSA and UL approvals)

For applications where the original 750A AC breaking capacity is critical, Littelfuse equivalents are the appropriate choice. For applications where 200A AC breaking capacity is sufficient, Eaton alternatives provide viable substitution.

Frequently Asked Questions (FAQ)

Q: Can I use 0314010.HXP as a direct replacement for the obsolete 0314010.H?

A: Yes. The 0314010.HXP is a direct parametric equivalent with identical electrical ratings (10 A, 250 V AC, 125 V DC), fuse type (ceramic cartridge), response time (fast blow), and mechanical dimensions (0.250" x 1.250"). The primary difference is product status (active versus obsolete) and improved RoHS3 compliance.

Q: What is the difference between the four Littelfuse substitute parts (0314010.HXP, 0314010.MXANP, 0314010.MXP, 0314010.VXP)?

A: All four parts are electrically and mechanically identical. Differences exist only in packaging format (all are Bulk), regional compliance certifications, and inventory availability. Selection should be based on specific certification requirements for your application region and supply chain preferences.

Q: Can I use Eaton BK/ABC-B-10 or BP/ABC-10 instead of Littelfuse parts?

A: These Eaton parts are functionally equivalent for the core electrical specifications (10 A, 250 V AC, 125 V DC, ceramic cartridge, fast blow). However, the breaking capacity at rated AC voltage is lower (200A AC versus 750A AC). Use Eaton alternatives only if your application does not require the higher 750A AC breaking capacity. Verify that the slightly different melting I²t values (215.6 and 208.8 versus 206) are acceptable for your circuit protection requirements.

Q: Are all substitute parts compatible with 3AB and 3AG fuse holders?

A: All Littelfuse equivalents (0314010.HXP, 0314010.MXANP, 0314010.MXP, 0314010.VXP) are fully compatible with 3AB and 3AG holders. The Eaton BK/ABC-B-10 is also compatible with these standard holders. The Eaton BP/ABC-10 uses a non-standard cartridge package; verify holder compatibility before selection.

Q: What compliance certifications should I consider when selecting a substitute?

A: The original 0314010.H holds CSA, METI, and UL approvals. Littelfuse equivalents expand this to include CE, K-MARK, and PSE certifications. Eaton parts hold CSA and UL approvals. Select based on the regulatory requirements of your target market and application region.

Q: Does RoHS compliance matter for this fuse selection?

A: RoHS compliance depends on your application and market requirements. The original 0314010.H is RoHS non-compliant. All four Littelfuse equivalents are ROHS3 Compliant. The Eaton BP/ABC-10 is RoHS Compliant, while BK/ABC-B-10 is non-compliant. If RoHS compliance is required, select from the Littelfuse equivalents or Eaton BP/ABC-10.
