SCHURTER 0034.5140 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.5140 is a 6 A, 250 V AC/DC fast-blow glass cartridge fuse in 3AB/3AG package format (1/4" x 1-1/4"). This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs. The fuse requires a compatible holder and is approved by CSA and UL standards. Substitutes must maintain electrical and mechanical compatibility while meeting the same safety certifications and performance characteristics.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Primary Compatibility Criteria:

Current Rating: 6 A (exact match required)
Voltage Rating (AC): 250 V (exact match required)
Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Response Time: Fast Blow (exact match required)
Size / Dimension: 0.250" Dia x 1.252" L or 0.250" Dia x 1.250" L (within tolerance)

Secondary Compatibility Criteria:

Breaking Capacity @ Rated Voltage: 200 A (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match or wider range acceptable)
Mounting Type: Requires Holder (exact match required)

All substitute parts listed meet these criteria. The SCHURTER 8020.5076 is excluded from direct substitution due to higher voltage rating (500 V) and ceramic construction, representing a different product category despite similar package dimensions.

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing status, providing long-term availability compared to the obsolete SCHURTER 0034.5140. Selection should prioritize parts with the broadest certification coverage:

Littelfuse 0312006 Series (HXP, MXP, VXP): Approved by CE, CSA, KC, PSE, and UL. These parts offer the widest international compliance scope and are recommended for applications requiring multi-region certification.

Eaton AGC Series (AGC-6-R, BK/AGC-6-R): Approved by CSA and UL. The BK/AGC-6-R variant has the highest inventory availability (8,585 units) and is suitable for North American applications.

Bel Fuse 3AG 6-R: Approved by CE, CSA, cURus, and PSE. Provides strong compliance coverage with 7,786 units in stock.

OptiFuse FSA-6A: Approved by cULus and UL 248. Suitable for applications requiring UL 248 compliance.

All substitute parts maintain identical electrical performance (6 A, 250 V, 200 A breaking capacity, fast-blow response) and mechanical compatibility (3AB/3AG package, 1/4" x 1-1/4" form factor) with the original SCHURTER 0034.5140.

Frequently Asked Questions (FAQ)

Q: Can I use a 6.3 A fuse as a substitute for the 6 A SCHURTER 0034.5140?

A: No. Current rating must be an exact match. The SCHURTER 8020.5076 (6.3 A, 500 V ceramic fuse) is not a valid substitute despite similar package dimensions. Using a higher current-rated fuse compromises circuit protection.

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

A: Yes. All substitute parts use the 3AB/3AG package format with 1/4" x 1-1/4" dimensions. Minor dimensional variations (0.250" x 1.250" vs. 0.250" x 1.252") are within standard holder tolerances and do not affect mechanical fit.

Q: What is the difference between the Littelfuse 0312006.HXP, 0312006.MXP, and 0312006.VXP variants?

A: All three variants are electrically and mechanically identical (6 A, 250 V, fast-blow, 3AB/3AG package). Differences are internal construction or manufacturing batches. Selection can be based on inventory availability or specific procurement requirements.

Q: Which substitute offers the best availability?

A: The Eaton BK/AGC-6-R has the highest inventory (8,585 units), followed by Bel Fuse 3AG 6-R (7,786 units) and Littelfuse 0312006.MXP (4,192 units).

Q: Do all substitutes meet RoHS compliance?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the environmental compliance of the original SCHURTER 0034.5140.

Q: Can I mix different substitute brands in the same circuit or system?

A: Yes. All substitutes meet identical electrical and safety specifications. However, for consistency and traceability, using a single manufacturer across a system is recommended for maintenance and documentation purposes.
