Littelfuse 023002.5VXP Glass Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The Littelfuse 023002.5VXP is a 2.5 A, 250 V AC / 125 V DC glass cartridge fuse with slow-blow response characteristics. This through-hole mounted component is designed for circuit protection in applications requiring non-standard axial cartridge form factors. The part maintains active product status with full compliance to international safety standards including CE, CSA, PSE, and UL certifications. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and approval certifications align with the original specification, enabling direct replacement in existing designs without circuit modification.

Substitute Part Grouping Explanation

Substitute parts for the Littelfuse 023002.5VXP are qualified based on strict equivalence across the following critical parameters:

• Current Rating: 2.5 A (exact match required)
• Voltage Rating AC: 250 V (exact match required)
• Voltage Rating DC: 125 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Size / Dimension: 0.177" Dia x 0.571" L / 4.50mm x 14.50mm (exact match required)
• Melting I²t: 50 (exact match required)
• DC Cold Resistance: 0.0502 Ohms (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Approval Agencies: CE, CSA, PSE, UL (all certifications present)
• RoHS Status: ROHS3 Compliant (exact match required)

The identified substitute parts 023002.5HXP and 023002.5MXP meet all electrical and mechanical equivalence criteria. Variation in Breaking Capacity at Rated Voltage does not affect substitution eligibility, as this parameter is not specified as a selection criterion for this product category.

Parameter Comparison

Engineering Selection Recommendations

All three parts—023002.5VXP, 023002.5HXP, and 023002.5MXP—are active products from Littelfuse Inc. with identical electrical specifications and full compliance to CE, CSA, PSE, and UL standards. Each part carries ROHS3 compliance and REACH Unaffected status. Selection between these parts may be based on inventory availability and lead time considerations, as all three are functionally equivalent for circuit protection applications requiring 2.5 A slow-blow glass cartridge fuses rated for 250 V AC / 125 V DC operation.

Frequently Asked Questions (FAQ)

Q: Can 023002.5HXP or 023002.5MXP be used as direct replacements for 023002.5VXP?

A: Yes. Both substitute parts meet all electrical and mechanical equivalence criteria, including current rating, voltage ratings, response time, fuse type, package form factor, dimensions, and thermal characteristics. All three parts carry identical international safety certifications.

Q: Are there any differences in breaking capacity between the main part and substitutes?

A: The 023002.5VXP specifies 100A AC breaking capacity, while 023002.5HXP and 023002.5MXP specify 35A AC breaking capacity. Both values are valid for this product category and do not affect substitution eligibility based on the provided specification parameters.

Q: Do all three parts have the same physical dimensions?

A: Yes. All three parts share identical dimensions of 0.177" diameter by 0.571" length (4.50mm x 14.50mm), ensuring mechanical compatibility in through-hole mounting applications.

Q: Are there temperature or environmental limitations for these fuses?

A: All three parts operate across the same temperature range of -55°C to 125°C. No additional environmental restrictions are specified beyond standard RoHS3 and REACH compliance requirements.

Q: Which part should be selected if all three are available?

A: Selection should be based on inventory availability, lead time, and procurement cost. All three parts are functionally equivalent and carry active product status with full regulatory compliance.
