Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence Criteria:

• Current Rating: 8 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 200 A (exact match required)

Mechanical Equivalence Criteria:

• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Size / Dimension: 0.250" Dia x 1.250" L (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Mounting Type: Requires Holder (exact match required)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Product Status: Active (minimum requirement)
• Approval Agencies: CSA and/or UL certification (minimum requirement)

All substitute parts listed meet these criteria and are suitable for direct replacement in applications requiring AGC-8-R fuses.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement Equivalents:

The BK/AGC-8-R (Eaton) is a direct equivalent to the AGC-8-R. Both parts are manufactured by Eaton - Electronics Division and share identical electrical and mechanical specifications. Selection between these two part numbers may be based on inventory availability or internal part numbering conventions.

Cross-Manufacturer Substitutes:

The 0312008.MXP and 0312008.VXP (Littelfuse Inc.) are functionally equivalent substitutes. Both parts meet all electrical and mechanical requirements for AGC-8-R replacement. Littelfuse parts carry expanded approval agency certifications (CE, CSA, KC, PSE, UL) compared to the Eaton baseline (CSA, UL). All parts maintain ROHS3 compliance and active product status, ensuring long-term availability and regulatory conformance.

Selection of Littelfuse alternatives is appropriate when cross-manufacturer sourcing is required or when expanded international certifications are beneficial for end-use applications.

Frequently Asked Questions (FAQ)

Q: Can the BK/AGC-8-R be used as a direct replacement for AGC-8-R?

A: Yes. Both parts are manufactured by Eaton - Electronics Division and share identical electrical ratings (8 A, 250 V AC), response time (Fast Blow), mechanical package (3AB, 3AG, 1/4" x 1-1/4"), and approval certifications (CSA, UL). Direct substitution is supported.

Q: Are Littelfuse 0312008.MXP and 0312008.VXP interchangeable with AGC-8-R?

A: Yes. Both Littelfuse parts match all critical electrical and mechanical parameters: 8 A current rating, 250 V AC voltage rating, Fast Blow response, 200 A breaking capacity, and 3AB/3AG package dimensions. Both are ROHS3 compliant and carry CSA and UL certifications. Mechanical fit and electrical performance are equivalent.

Q: What is the difference between 0312008.MXP and 0312008.VXP?

A: Both parts are manufactured by Littelfuse Inc. in the 312 series and share identical electrical ratings, mechanical dimensions, and approval certifications. The difference in part number designation reflects internal Littelfuse product line categorization. Both are functionally equivalent for AGC-8-R replacement applications.

Q: Do all substitute parts require the same fuse holder?

A: Yes. All listed parts use the 3AB and 3AG fuse holder standard with 1/4" x 1-1/4" dimensions. No holder modification or upgrade is required when substituting between AGC-8-R, BK/AGC-8-R, 0312008.MXP, or 0312008.VXP.

Q: Are there any differences in DC cold resistance between these parts?

A: The AGC-8-R and BK/AGC-8-R (Eaton) specify 0.009 Ohms DC cold resistance. The Littelfuse parts (0312008.MXP and 0312008.VXP) specify 0.0122 Ohms. This difference does not affect circuit protection function or compatibility in standard applications. Both values are within acceptable ranges for fast-blow cartridge fuses.

Q: Which parts have the broadest international approvals?

A: The Littelfuse parts (0312008.MXP and 0312008.VXP) carry CE, CSA, KC, PSE, and UL certifications. The Eaton parts (AGC-8-R and BK/AGC-8-R) carry CSA and UL certifications. Littelfuse alternatives are preferred for applications requiring expanded international market compliance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four parts (AGC-8-R, BK/AGC-8-R, 0312008.MXP, and 0312008.VXP) are ROHS3 compliant and suitable for applications with RoHS regulatory requirements.
