Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/AGC-5PP-R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 5 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Glass
• Response Time: Fast Blow
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4"
• Breaking Capacity @ Rated Voltage: 200 A
• Operating Temperature Range: -55°C ~ 125°C
• Size / Dimension: 0.250" Dia x 1.250" L (6.35mm x 31.75mm)

All substitute parts listed maintain identical values across these parameters, ensuring direct functional equivalence. Variations in secondary parameters such as melting I²t and DC cold resistance do not preclude substitution when all mandatory parameters align.

Parameter Comparison

Engineering Selection Recommendations

Eaton - Electronics Division Substitutes:

BK/AGC-5-R is a direct parametric equivalent manufactured by Eaton - Electronics Division. This part maintains identical electrical and mechanical specifications to the BK/AGC-5PP-R. Both parts carry CSA and UL approval certifications and are rated for the same operating temperature range. Selection of BK/AGC-5-R provides continuity within the same manufacturer's product line while maintaining full compliance with circuit protection requirements.

Littelfuse Inc. Substitutes:

The 0312005.HXP, 0312005.MXP, and 0312005.VXP part numbers are manufactured by Littelfuse Inc. and provide parametric equivalence across all mandatory electrical and mechanical parameters. These parts carry expanded approval certifications including CE, CSA, KC, PSE, and UL, providing broader international compliance coverage. All three Littelfuse variants are rated for identical current, voltage, breaking capacity, and operating temperature specifications.

Compliance Considerations:

All substitute parts listed maintain active product status and are RoHS3 compliant and REACH unaffected. Selection among these alternatives is based on availability, supply chain requirements, and certification scope needed for the target application.

Frequently Asked Questions (FAQ)

Q: Can BK/AGC-5-R be used as a direct replacement for BK/AGC-5PP-R?

A: Yes. BK/AGC-5-R is a parametric equivalent with identical current rating (5 A), voltage rating (250 V AC), fuse type (cartridge, glass), response time (fast blow), package designation (3AB, 3AG), breaking capacity (200 A), and physical dimensions (0.250" Dia x 1.250" L). Both parts are manufactured by Eaton - Electronics Division and carry CSA and UL certifications.

Q: Are Littelfuse 0312005 series fuses compatible with 3AB and 3AG fuse holders?

A: Yes. The 0312005.HXP, 0312005.MXP, and 0312005.VXP part numbers are all rated for 3AB and 3AG fuse holders with identical physical dimensions of 0.250" Dia x 1.250" L (6.35mm x 31.75mm). These parts are mechanically and electrically compatible with the same holder types as the BK/AGC-5PP-R.

Q: What is the difference between the three Littelfuse 0312005 variants?

A: The 0312005.HXP, 0312005.MXP, and 0312005.VXP variants share identical electrical and mechanical specifications. All three maintain 5 A current rating, 250 V AC voltage rating, fast-blow response time, 200 A breaking capacity, and -55°C ~ 125°C operating temperature range. Differences in part number designation reflect internal manufacturing or packaging variations that do not affect functional equivalence.

Q: Do all substitute parts carry the same approval certifications as BK/AGC-5PP-R?

A: BK/AGC-5PP-R carries CSA and UL certifications. The Littelfuse 0312005 series parts carry expanded certifications including CE, CSA, KC, PSE, and UL. BK/AGC-5-R carries the same CSA and UL certifications as the primary part. Selection should be based on the certification requirements of the target application.

Q: Can these fuses be used in applications requiring both AC and DC operation?

A: All listed parts are rated for 5 A at 250 V AC/DC operation. The specifications provided confirm AC voltage rating; DC compatibility is inherent to the cartridge glass fuse design across all listed part numbers.

Q: What is the significance of the melting I²t parameter variation?

A: The BK/AGC-5PP-R specifies melting I²t of 131.5, while Littelfuse 0312005 variants specify 50. Both values fall within the fast-blow fuse classification for 5 A cartridge fuses. The variation reflects different thermal mass characteristics between manufacturers but does not preclude substitution when all other mandatory parameters align. Application-specific thermal requirements should be evaluated if precise I²t matching is critical.
