Littelfuse 0253003.VXL Equivalent & Substitute Parts

Part Overview

The Littelfuse 0253003.VXL is a 3 A, 125 V AC/DC board mount axial fuse from the PICO® II 253 series. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The fuse is designed for through-hole mounting applications requiring fast-blow response characteristics and operates across a temperature range of -55°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0253003.VXL is determined by the following critical parameters: current rating (3 A), voltage ratings (125 V AC and 125 V DC), response time (fast blow), mounting type (through hole), and physical dimensions. All substitute parts must maintain identical electrical performance characteristics and mechanical compatibility with the original design.

The substitute parts are grouped into two categories:

Parametric Equivalents (Littelfuse): Parts 0253003.M and 0253003.V are direct parametric equivalents from Littelfuse, maintaining all electrical specifications, dimensional tolerances, and performance characteristics. These parts differ only in packaging format (bulk) and product status (active vs. obsolete).

Direct Manufacturer Substitute (SCHURTER): Part 7010.6400.13 from SCHURTER Inc. provides functional equivalence with identical current, voltage, and response time ratings. This substitute maintains mechanical compatibility through equivalent axial package geometry, though with minor dimensional variations and different thermal operating limits.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (0253003.M and 0253003.V): These Littelfuse parts are recommended as first-choice substitutes. Both maintain identical electrical specifications, dimensional accuracy, and thermal operating range as the original 0253003.VXL. The distinction between these two parts is packaging format only; both are active products with full availability. Selection between 0253003.M and 0253003.V depends on procurement packaging requirements.

Secondary Substitute (7010.6400.13): The SCHURTER part provides functional equivalence for applications where dimensional tolerance and thermal operating range adjustments are acceptable. This substitute maintains the critical electrical parameters (3 A, 125 V AC/DC, fast blow) but operates within a reduced temperature range (-55°C to 85°C versus -55°C to 125°C). The melting I²t value of 2.4 differs from the original specification of 1.19, indicating different thermal response characteristics. Physical dimensions vary slightly, requiring PCB layout verification before implementation.

All substitute parts maintain ROHS3 compliance and are classified as active products with current manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can 0253003.M and 0253003.V be used interchangeably with 0253003.VXL?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (3 A, 125 V AC/DC), response time (fast blow), dimensions (0.103" Dia x 0.280" L), and operating temperature range (-55°C to 125°C). The only difference is packaging format (bulk versus tape/reel). Electrical and mechanical performance are equivalent.

Q: What are the limitations of using SCHURTER 7010.6400.13 as a substitute?

A: The SCHURTER part maintains electrical equivalence but has three notable differences: (1) operating temperature range is reduced to -55°C to 85°C, (2) physical dimensions are slightly different (0.093" Dia x 0.315" L), and (3) melting I²t is 2.4 instead of 1.19. Applications requiring operation above 85°C or with specific thermal response characteristics should use Littelfuse equivalents instead.

Q: Are there dimensional compatibility concerns with the SCHURTER substitute?

A: Yes. The SCHURTER 7010.6400.13 has different physical dimensions (0.093" Dia x 0.315" L) compared to the original (0.103" Dia x 0.280" L). PCB footprint and mechanical clearance must be verified before implementation. The Littelfuse substitutes (0253003.M and 0253003.V) have identical dimensions and require no layout modifications.

Q: Do all substitute parts maintain RoHS compliance?

A: Yes. All substitute parts listed (0253003.M, 0253003.V, and 7010.6400.13) are ROHS3 compliant, matching the compliance status of the original 0253003.VXL.

Q: Why is the original 0253003.VXL classified as obsolete?

A: The 0253003.VXL is obsolete, but active equivalents are available. The Littelfuse 0253003.M and 0253003.V are direct replacements with identical specifications and are currently in active production. These parts should be used for new designs and ongoing production requirements.
