Littelfuse 0332010.MXP Ceramic Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The Littelfuse 0332010.MXP is a 10 A ceramic cartridge fuse rated for 250 V AC and 125 V DC operation. This component is classified as obsolete, requiring identification of active equivalent alternatives for continued system support. The 3AB/3AG form factor (0.250" diameter × 1.250" length) necessitates compatible holder-based mounting. Substitute parts must maintain identical electrical ratings and mechanical dimensions to ensure direct functional replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0332010.MXP is determined by strict equivalence across the following parameters:

• 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" × 1-1/4" (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

All substitute parts listed below meet these criteria and are manufactured by Littelfuse Inc. within the active 314 series. Substitutes differ only in internal construction characteristics (melting I²t, breaking capacity, and approval agency certifications) while maintaining identical external electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 0332010.MXP (obsolete, 332 series) is directly substitutable with any of the four active 314 series alternatives: 0314010.MXP, 0314010.HXP, 0314010.MXANP, or 0314010.VXP. All substitute parts maintain identical electrical and mechanical specifications required for direct replacement in existing circuits and holder assemblies.

Selection among active substitutes should be based on:

• Approval agency certifications required by the end application (CE, CSA, K-MARK, KC, PSE, UL)
• Inventory availability and lead time requirements
• Regional compliance requirements (REACH status: all substitutes are REACH Unaffected)

All substitute parts are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), matching the environmental specifications of the original component.

Frequently Asked Questions (FAQ)

Q: Can the 0314010 series parts directly replace the 0332010.MXP in existing applications?

A: Yes. All four 0314010 variants (MXP, HXP, MXANP, VXP) are direct functional replacements. They maintain identical current rating (10 A), voltage ratings (250 V AC / 125 V DC), fuse type (ceramic cartridge), response time (fast blow), and mechanical dimensions (3AB/3AG, 0.250" × 1.250").

Q: What are the differences between the substitute parts?

A: The substitute parts differ in internal construction characteristics and approval agency certifications. Melting I²t values and breaking capacity ratings differ between the obsolete 332 series and active 314 series, but all substitutes meet the same external electrical and mechanical requirements for circuit protection at 10 A, 250 V AC / 125 V DC.

Q: Are all substitute parts compatible with existing fuse holders?

A: Yes. All substitute parts use the 3AB/3AG form factor (0.250" diameter × 1.250" length) and require the same holder type as the original 0332010.MXP. No holder modifications are necessary.

Q: Which substitute part should I select?

A: Selection depends on your specific approval agency requirements. Verify which certifications (CE, CSA, K-MARK, KC, PSE, UL) are required for your application, then select the corresponding substitute part. All four options are functionally equivalent for circuit protection purposes.

Q: Are the substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant, matching the environmental compliance of the original 0332010.MXP.
