SCHURTER 0034.1739 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.1739 is a 200 mA, 250 V AC/DC fast-blow glass fuse cartridge in the 3AB/3AG package format (1/4" x 1-1/4"). This component is classified as obsolete, requiring identification of active equivalent parts for ongoing system support and maintenance. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and holder compatibility to ensure direct interchangeability in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

• Current Rating: 200 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Breaking Capacity: 35 A (exact match required)

All identified substitute parts meet these criteria. Dimensional tolerance between 0.250" Dia x 1.250" L and 0.250" Dia x 1.252" L is within standard manufacturing specifications for this package class and does not affect holder compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are electrically and mechanically equivalent to the SCHURTER 0034.1739 and are suitable for direct replacement in applications requiring a 200 mA, 250 V AC/DC fast-blow glass fuse cartridge in the 3AB/3AG package.

The Littelfuse 312 series parts (0312.200MXP, 0312.200VXP, 0312.200HXP) are active products with extended operating temperature range (-55°C ~ 125°C) and hold CE, CSA, and UL certifications. These parts provide the broadest regulatory compliance coverage.

The Eaton AGC series parts (AGC-2/10-R and BK/AGC-2/10-R) are active products with CSA and UL certifications and extended operating temperature range (-55°C ~ 125°C). Both variants are functionally equivalent for this application.

Selection among active substitutes should be based on supply chain availability, lead time, and existing component qualification within the target application.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0034.1739 be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts meet the required electrical specifications (200 mA, 250 V AC/DC, fast-blow response) and mechanical package requirements (3AB/3AG, 1/4" x 1-1/4"). Dimensional variation between 0.250" Dia x 1.252" L and 0.250" Dia x 1.250" L is within standard manufacturing tolerance for this package class and does not affect holder compatibility.

Q: What is the difference between the Littelfuse 0312.200MXP, 0312.200VXP, and 0312.200HXP variants?

A: All three Littelfuse parts are electrically and mechanically identical with respect to the parameters specified for this application. Differences, if any, relate to internal construction or packaging designations not provided in the technical data. For this substitution application, they are functionally equivalent.

Q: Are there differences between the Eaton AGC-2/10-R and BK/AGC-2/10-R?

A: Both Eaton parts meet identical electrical and mechanical specifications for this application. The "BK/" prefix designation may indicate packaging or internal construction variation not specified in the provided technical data. For direct replacement purposes, they are functionally equivalent.

Q: What certifications should I verify for my specific application?

A: The SCHURTER 0034.1739 holds CSA certification. Littelfuse 312 series parts hold CE, CSA, and UL certifications. Eaton AGC series parts hold CSA and UL certifications. Verify that the selected substitute part's certification profile meets your application's regulatory requirements.

Q: Does the extended operating temperature range of substitute parts affect compatibility?

A: No. The substitute parts' extended operating temperature ranges (-55°C ~ 125°C versus the original -40°C ~ 85°C) represent improved capability and do not affect electrical or mechanical compatibility. The substitute parts will function correctly within the original part's temperature specification.
