Substitute Part Grouping Explanation

Substitution for the SCHURTER 0034.5241 is determined by the following critical parameters:

Current Rating: 6.25 A (exact match required)
Voltage Rating: 250 V AC (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Response Time: Slow Blow (exact match required)
Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
Breaking Capacity: 200 A (exact match required)
Physical Dimensions: 0.250" Dia x 1.250" L (exact match required)

All substitute parts listed below meet these electrical and mechanical parameters. Parts are grouped by manufacturer and product status (active vs. obsolete).

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing status, ensuring long-term availability and supply chain continuity. The Littelfuse 313 series parts (03136.25MXP, 03136.25HXIDP, 03136.25HXP, 03136.25VXIDP, 03136.25VXP) provide expanded international approvals including K-MARK, PSE, and KC certifications, supporting broader geographic deployment requirements. The Eaton MDL series (MDL-6-1/4-R, BK/MDL-6-1/4-R) maintains CSA and UL compliance with established supply channels. Selection should be based on certification requirements for the target application region and existing supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can I use a 6.3 A fuse as a substitute for the 6.25 A requirement?

A: No. Current rating must match exactly at 6.25 A. A 6.3 A fuse will not provide the same protection characteristics and is not an acceptable substitute.

Q: Are all listed parts mechanically compatible with 3AB/3AG holders?

A: Yes. All substitute parts are specified for 3AB/3AG package format with identical physical dimensions (0.250" Dia x 1.250" L / 6.35mm x 31.75mm) and mount in the same holder hardware.

Q: What is the difference between the Littelfuse variants (MXP, HXIDP, HXP, VXIDP, VXP)?

A: All variants meet the core electrical and mechanical parameters. Differences exist in melting I²t characteristics and specific regional certifications. Selection depends on application-specific thermal response requirements and geographic compliance mandates.

Q: Why is the SCHURTER 0034.5241 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by SCHURTER. Active equivalent parts from Littelfuse and Eaton provide identical electrical and mechanical performance for direct replacement.

Q: Do all substitute parts have the same breaking capacity?

A: Yes. All listed substitutes maintain 200 A breaking capacity at rated voltage, matching the original SCHURTER specification.

Q: Are there voltage or temperature derating considerations when switching manufacturers?

A: No. All substitute parts operate within the same voltage rating (250 V AC) and temperature range (-55°C ~ 125°C), with no derating required for direct substitution.
