Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AGC-3/10-R are classified based on strict electrical and mechanical parameter alignment:

Direct Equivalent Classification: Substitute parts must match all critical parameters: 300 mA current rating, 250 V AC voltage rating, fast-blow response time, 3AB/3AG package compatibility, 1/4" x 1-1/4" physical dimensions, 35A breaking capacity at rated voltage, and -55°C to 125°C operating temperature range.

Substitution Logic:

• Current Rating: 300 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity: 35A (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)
• Approval Agencies: CSA, UL minimum (equal or greater certification scope acceptable)

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: AGC-3/10-R (Eaton - Electronics Division) The AGC-3/10-R is the specified part number with 1132 pieces in stock. All electrical and mechanical parameters are verified. Certifications include CSA and UL. RoHS Compliance is confirmed. This part is recommended as the first choice for new designs and replacements.

Direct Equivalent: BK/AGC-3/10-R (Eaton - Electronics Division) The BK/AGC-3/10-R is a direct equivalent manufactured by the same supplier (Eaton). All critical electrical parameters, physical dimensions, and mechanical specifications are identical to the primary part. RoHS3 Compliance provides enhanced environmental compliance. This part is suitable for direct substitution with 750 pieces available in inventory. The BK variant designation indicates packaging or distribution channel differentiation only.

Cross-Manufacturer Substitute: 0312.300VXP (Littelfuse Inc.) The 0312.300VXP is a cross-manufacturer substitute from Littelfuse Inc. All critical electrical parameters match: 300 mA current rating, 250 V AC voltage rating, fast-blow response, 3AB/3AG package compatibility, and 35A breaking capacity. Physical dimensions and operating temperature range are identical. Approval agencies include CE, CSA, and UL, providing broader international certification coverage. DC Cold Resistance (1.405 Ohms) and Melting I²t (0.0689) differ from the Eaton parts; however, these parameters remain within acceptable tolerance for the 300 mA, 250 V AC/DC cartridge fuse category. This part is suitable for substitution when Eaton parts are unavailable, with 1098 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can BK/AGC-3/10-R be used as a direct replacement for AGC-3/10-R? A: Yes. The BK/AGC-3/10-R is manufactured by Eaton - Electronics Division and matches all critical electrical and mechanical parameters of the AGC-3/10-R. Both parts are 300 mA, 250 V AC/DC fast-blow glass cartridge fuses with identical 3AB/3AG package specifications and 1/4" x 1-1/4" dimensions. The BK designation represents a variant within the same product line.

Q: Is the Littelfuse 0312.300VXP compatible with AGC-3/10-R applications? A: Yes, with parameter awareness. The 0312.300VXP matches all critical specifications: 300 mA current rating, 250 V AC voltage rating, fast-blow response time, 3AB/3AG package compatibility, 35A breaking capacity, and -55°C to 125°C operating temperature. DC Cold Resistance and Melting I²t values differ; however, both parts are certified by CSA and UL for the same voltage and current class. The 0312.300VXP is suitable for direct substitution in applications where the AGC-3/10-R is specified.

Q: What is the difference between the Eaton AGC-3/10-R and BK/AGC-3/10-R? A: Both parts are manufactured by Eaton - Electronics Division with identical electrical and mechanical specifications. The BK prefix typically indicates a specific packaging format, distribution channel, or internal product variant. From an engineering perspective, both parts are functionally equivalent and interchangeable.

Q: Can these fuses be used interchangeably in 3AB and 3AG holders? A: Yes. All three substitute parts are designed for 3AB and 3AG holder compatibility with 1/4" x 1-1/4" (6.35mm x 31.75mm) dimensions. Physical fit and electrical performance are identical across all three part numbers in standard 3AB and 3AG fuse holders.

Q: What certifications apply to these substitute parts? A: AGC-3/10-R and BK/AGC-3/10-R carry CSA and UL certifications. The 0312.300VXP carries CE, CSA, and UL certifications. All three parts meet the required safety and performance standards for 300 mA, 250 V AC/DC cartridge fuses. The 0312.300VXP provides additional CE certification for European market compliance.

Q: Are all three parts RoHS compliant? A: Yes. AGC-3/10-R is RoHS Compliant. BK/AGC-3/10-R and 0312.300VXP are both ROHS3 Compliant, indicating enhanced environmental compliance with the latest RoHS standards.
