Substitute Part Grouping Explanation

Substitution eligibility for the BK/GDB-V-80MA is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Current Rating: 80 mA
• Voltage Rating (AC): 250 V
• Response Time: Fast Blow
• Breaking Capacity @ Rated Voltage: 35 A
• Melting I²t: 0.0012
• DC Cold Resistance: 5 Ohms

Mechanical Parameters (Must Match Exactly):

• Fuse Type: Cartridge, Glass
• Package / Case: 5mm x 20mm (Axial)
• Mounting Type: Through Hole

Compliance Parameters:

• RoHS Status: RoHS Compliant

The substitute part BK/S500-V-80-R meets all electrical and mechanical equivalence criteria. Both components are manufactured by Eaton - Electronics Division and maintain Active product status. The primary distinction is the series designation (GDB versus S500) and packaging format (standard versus bulk), which do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both BK/GDB-V-80MA and BK/S500-V-80-R are Active products manufactured by Eaton - Electronics Division with full RoHS compliance. Selection between these components is based on procurement and inventory requirements rather than functional performance differences.

BK/GDB-V-80MA is appropriate for applications requiring standard packaging with 860 pieces currently in stock.

BK/S500-V-80-R is appropriate for applications requiring bulk packaging with 740 pieces currently in stock.

Both components deliver identical electrical performance, mechanical fit, and compliance certifications. The choice between series designations (GDB versus S500) does not affect circuit functionality, protection characteristics, or reliability in equivalent 80 mA, 250 V AC/DC fast-blow fuse applications.

Frequently Asked Questions (FAQ)

Q: Can BK/S500-V-80-R be used as a direct replacement for BK/GDB-V-80MA in existing designs?

A: Yes. Both components are electrically and mechanically equivalent. All critical parameters including current rating, voltage rating, response time, breaking capacity, and physical dimensions are identical. The components are interchangeable in circuit applications.

Q: What is the difference between the GDB and S500 series?

A: The GDB and S500 series are different product lines from Eaton - Electronics Division. For the 80 mA, 250 V fast-blow specification, both series deliver identical electrical performance and mechanical form factor. The series designation reflects internal product categorization and does not affect functional equivalence.

Q: Does packaging format (standard versus bulk) affect component performance?

A: No. Packaging format affects only procurement quantity and storage considerations. The electrical and mechanical characteristics of the fuse element remain identical regardless of packaging format.

Q: Are both parts RoHS compliant?

A: Yes. Both BK/GDB-V-80MA and BK/S500-V-80-R are RoHS Compliant and suitable for applications requiring environmental compliance.

Q: What is the melting I²t value and why is it important for substitution?

A: The melting I²t value of 0.0012 defines the thermal energy required to melt the fuse element. This parameter must match exactly between substitute parts to ensure identical protection characteristics and response behavior in the circuit.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. Both components are rated for 250 V AC/DC operation, indicating compatibility with alternating current and direct current applications at the specified voltage level.
