Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 0332002.HXP is based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Current Rating: 2 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)

All three substitute parts (0314002.HXP, 0314002.MXP, 0314002.VXP) meet these criteria and are manufactured by Littelfuse Inc. in the active Series 314 line. These parts are direct functional equivalents suitable for replacement in applications previously using the 0332002.HXP.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (0314002.HXP, 0314002.MXP, 0314002.VXP) are active Littelfuse Series 314 components with identical electrical and mechanical specifications to the obsolete 0332002.HXP. Selection among these three alternatives is based on packaging and availability requirements:

0314002.HXP is designated as the manufacturer-recommended substitute and carries expanded regulatory approvals (CSA, UL in addition to CE and PSE), providing broader compliance coverage for international applications.

0314002.MXP and 0314002.VXP are parametric equivalents with identical electrical performance and regulatory compliance. These parts differ only in packaging designation and internal manufacturing specifications not affecting functional performance.

All substitute parts are ROHS3 compliant, operate across the full -55°C to 125°C temperature range, and maintain MSL 1 (unlimited moisture sensitivity level) classification. The substitute parts demonstrate improved breaking capacity specifications (100A AC, 10kA DC) compared to the main part (100A), providing enhanced circuit protection margins.

Frequently Asked Questions (FAQ)

Q: Can 0314002.HXP, 0314002.MXP, and 0314002.VXP be used interchangeably with 0332002.HXP?

A: Yes. All three substitute parts match the critical electrical parameters (2 A, 250 V AC, 125 V DC, fast-blow ceramic cartridge) and mechanical specifications (3AB/3AG form factor, 1/4" x 1-1/4" dimensions). They are direct functional replacements suitable for any application using the obsolete 0332002.HXP.

Q: What is the difference between the three substitute part numbers?

A: The three parts are electrically and mechanically identical. Differences exist only in packaging designation and internal manufacturing specifications. Selection should be based on packaging availability and procurement requirements.

Q: Are the substitute parts compatible with existing fuse holders designed for 0332002.HXP?

A: Yes. All substitute parts use the same 3AB, 3AG package specification and 1/4" x 1-1/4" physical dimensions, ensuring compatibility with any holder designed for the original part.

Q: What regulatory approvals apply to the substitute parts?

A: The substitute parts carry CE, CSA, PSE, and UL approvals. The main part carried CE, cULus, and PSE approvals. The substitute parts provide expanded regulatory coverage suitable for broader market applications.

Q: Are there any performance differences between the main part and substitutes?

A: The substitute parts feature improved breaking capacity specifications (100A AC, 10kA DC versus 100A for the main part) and higher melting I²t values (11 versus 0.56), providing enhanced circuit protection performance while maintaining identical current and voltage ratings.
