Substitute Part Grouping Explanation

Substitution eligibility for the GFA-1/100 is determined by strict equivalence across the following critical parameters:

• Current Rating: 10 mA (exact match required)
• Voltage Rating (AC): 125 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) with dimensions 0.146" Dia x 0.299" L (exact match required)
• Breaking Capacity @ Rated Voltage: 50 A (exact match required)

The substitute part BK/GFA-1/100 meets all electrical and mechanical parameters specified for the GFA-1/100. Both parts are manufactured by Eaton - Electronics Division within the GFA series and maintain identical functional characteristics. Substitution is valid based on parametric equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both GFA-1/100 and BK/GFA-1/100 are Active status products manufactured by Eaton - Electronics Division with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

RoHS Compliance: The BK/GFA-1/100 variant is RoHS Compliant, while the GFA-1/100 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must use BK/GFA-1/100.

Regulatory Certifications: The GFA-1/100 carries CSA and UR approvals. The BK/GFA-1/100 carries CSA and UL approvals. Both certifications are recognized standards; selection depends on specific application certification requirements.

Inventory Availability: GFA-1/100 has 763 units in stock; BK/GFA-1/100 has 911 units in stock. Both parts are available for immediate procurement.

HTSUS Classification: GFA-1/100 is classified under 8536.10.0040; BK/GFA-1/100 is classified under 8536.10.0020. This distinction may affect tariff and import/export considerations.

For applications without RoHS mandates, either part is functionally equivalent. For RoHS-regulated applications, BK/GFA-1/100 is the required selection.

Frequently Asked Questions (FAQ)

Q: Can BK/GFA-1/100 be used as a direct replacement for GFA-1/100 in existing designs?

A: Yes. Both parts share identical current rating (10 mA), voltage rating (125 V AC), response time (Fast Blow), mounting type (Through Hole), package dimensions (0.146" Dia x 0.299" L), and breaking capacity (50 A). No circuit modifications are required.

Q: What is the difference between GFA-1/100 and BK/GFA-1/100?

A: The primary differences are RoHS compliance status (BK/GFA-1/100 is RoHS Compliant; GFA-1/100 is not) and regulatory certifications (GFA-1/100 carries UR approval; BK/GFA-1/100 carries UL approval). All electrical and mechanical parameters are identical.

Q: Which part should be selected for new designs?

A: For applications subject to RoHS regulations, BK/GFA-1/100 is required. For applications without RoHS mandates, either part is acceptable based on certification requirements and inventory availability.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical dimensions of 0.146" Dia x 0.299" L (3.70mm x 7.60mm) and use the same Cartridge, Non-Standard (Axial) package. Board layout and footprint compatibility is maintained.

Q: What is the breaking capacity of these fuses?

A: Both GFA-1/100 and BK/GFA-1/100 have a breaking capacity of 50 A at rated voltage (125 V AC).

Q: Are these parts suitable for AC and DC applications?

A: Yes. Both parts are rated for 125 V AC/DC operation with 10 mA current rating and Fast Blow response characteristics.
