Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AGC-3/8-R are identified based on strict equivalence of the following parameters:

Critical Matching Parameters:

• Current Rating: 375 mA
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Glass
• Response Time: Fast Blow
• Package / Case: 3AB, 3AG, 1/4" × 1-1/4"
• Size / Dimension: 0.250" Dia × 1.250" L (6.35 mm × 31.75 mm)
• Breaking Capacity @ Rated Voltage: 35 A
• Operating Temperature Range: -55°C ~ 125°C

All identified substitute parts meet these electrical and mechanical requirements. Substitutes are grouped into two categories: direct manufacturer equivalents from Eaton - Electronics Division, and cross-manufacturer alternatives from Littelfuse Inc. that satisfy identical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Eaton - Electronics Division): BK/AGC-3/8-R is a direct equivalent to AGC-3/8-R from the same manufacturer. Both parts share identical electrical specifications, mechanical dimensions, and thermal characteristics. BK/AGC-3/8-R carries ROHS3 compliance status compared to the base RoHS compliance of AGC-3/8-R. Both maintain CSA and UL approvals. Selection between these two Eaton variants depends on specific RoHS compliance requirements of the end application.

Cross-Manufacturer Alternatives (Littelfuse Inc.): 0312.375MXP and 0312.375VXP are Littelfuse equivalents that match all critical electrical and mechanical parameters. Both parts are rated for 375 mA at 250 V AC/DC with fast-blow response and identical package dimensions. Littelfuse parts carry expanded approval certifications including CE in addition to CSA and UL. Both are ROHS3 compliant and REACH unaffected. The Melting I²t value (0.185) and DC Cold Resistance (0.825 Ohms) differ from the Eaton AGC-3/8-R (0.09 and 0.703 Ohms respectively), but remain within acceptable parameters for the 375 mA, 250 V cartridge fuse category. Selection of Littelfuse alternatives is appropriate when cross-manufacturer sourcing or expanded certifications are required.

Frequently Asked Questions (FAQ)

Q: Can BK/AGC-3/8-R be used as a direct replacement for AGC-3/8-R? A: Yes. BK/AGC-3/8-R is a direct equivalent from Eaton - Electronics Division with identical electrical ratings (375 mA, 250 V), response characteristics (fast-blow), and mechanical dimensions (1/4" × 1-1/4"). Both parts are approved by CSA and UL and are RoHS compliant.

Q: What is the difference between Eaton AGC-3/8-R and Littelfuse 0312.375MXP or 0312.375VXP? A: All three parts share identical current rating (375 mA), voltage rating (250 V), response time (fast-blow), and package dimensions (3AB, 3AG, 1/4" × 1-1/4"). Littelfuse parts have different Melting I²t values (0.185 versus 0.09) and DC Cold Resistance (0.825 Ohms versus 0.703 Ohms). Littelfuse parts include CE certification in addition to CSA and UL. All are ROHS3 compliant.

Q: Are the Littelfuse 0312.375MXP and 0312.375VXP interchangeable with each other? A: Yes. Both Littelfuse parts share identical electrical specifications, mechanical dimensions, response characteristics, and approval certifications. They are functionally equivalent for circuit protection applications requiring 375 mA, 250 V fast-blow fuses in 3AB/3AG holders.

Q: What holder types are compatible with these fuses? A: All substitute parts require 3AB or 3AG fuse holders. The mechanical dimensions of 0.250" diameter × 1.250" length (6.35 mm × 31.75 mm) are standardized across all listed parts and are compatible with standard 3AB and 3AG holder designs.

Q: Can these fuses operate across the full temperature range in all applications? A: All listed parts are rated for operation from -55°C to 125°C. Actual operating performance depends on the specific circuit design and thermal management of the application. The operating temperature range defines the environmental limits within which the fuse maintains its specified electrical characteristics.

Q: What approval certifications should I verify for my application? A: AGC-3/8-R and BK/AGC-3/8-R carry CSA and UL approvals. Littelfuse 0312.375MXP and 0312.375VXP carry CE, CSA, and UL approvals. Verify that the selected part's certification set meets the regulatory requirements of your target market and application.
