Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/GDB-V-630MA is determined by strict alignment of the following parameters:

Primary Substitution Criteria:

• Current Rating: 630 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)

Secondary Compatibility Parameters:

• Melting I²t: 0.35 - 0.41 (acceptable variance within thermal performance envelope)
• DC Cold Resistance: 0.19 - 0.2 Ohms (acceptable variance within circuit resistance tolerance)
• Approval Agencies: UL, VDE, or equivalent international certifications

All identified substitute parts meet these criteria and are classified as direct or similar equivalents based on manufacturer and series designation.

Parameter Comparison

Engineering Selection Recommendations

BK/S500-V-630-R (Direct Substitute - Eaton): This part is a direct equivalent manufactured by Eaton - Electronics Division. It maintains identical electrical and mechanical specifications to the BK/GDB-V-630MA. The S500 series carries expanded approval certifications including BSI, CCC, CSA, cULus, IMQ, SEMKO, and VDE, providing broader international compliance coverage. Packaging is Bulk format. This substitute is suitable for applications requiring Eaton product continuity or expanded regulatory approvals.

0217.630MXEP (Similar Substitute - Littelfuse): This part is manufactured by Littelfuse Inc. under the 217 series and meets all primary substitution criteria. The melting I²t value is 0.41 (compared to 0.35 for the main part), representing acceptable variance within the thermal performance envelope. DC cold resistance is 0.19 Ohms (compared to 0.2 Ohms), within acceptable tolerance. Physical dimensions are 0.228" Dia x 0.886" L (5.80mm x 22.50mm), representing minor dimensional variance compatible with standard 5mm x 20mm through-hole footprints. Operating temperature range is specified as -55°C ~ 125°C. Approval certifications include CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. ROHS3 compliance and REACH Unaffected status are documented. This substitute is suitable for applications requiring cross-manufacturer sourcing or extended temperature operation.

All substitute parts are Active product status and maintain RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can BK/S500-V-630-R be used as a direct replacement for BK/GDB-V-630MA?

A: Yes. Both parts are manufactured by Eaton - Electronics Division and share identical electrical ratings (630 mA, 250 V AC), fuse type (Cartridge, Glass), response time (Fast Blow), package dimensions (5mm x 20mm Axial), and breaking capacity (35 A). Both are Active product status and RoHS compliant. The S500 series carries additional international certifications (BSI, CCC, CSA, cULus, IMQ, SEMKO, VDE) compared to the GDB series (UL, VDE).

Q: What is the difference between BK/GDB-V-630MA and 0217.630MXEP?

A: The primary differences are manufacturer (Eaton vs. Littelfuse), series designation (GDB vs. 217), and minor parameter variations. The 0217.630MXEP has a melting I²t of 0.41 versus 0.35, and DC cold resistance of 0.19 Ohms versus 0.2 Ohms. Physical dimensions are 5.80mm x 22.50mm versus 5.54mm x 21.10mm. The Littelfuse part includes operating temperature specification (-55°C ~ 125°C) and ROHS3 compliance. All electrical ratings and breaking capacity are identical.

Q: Are there packaging differences between substitute parts?

A: Yes. BK/GDB-V-630MA packaging is listed as "-" (not specified). BK/S500-V-630-R is supplied in Bulk packaging. 0217.630MXEP is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility for through-hole mounted components.

Q: Do all substitute parts have the same approval certifications?

A: No. BK/GDB-V-630MA carries UL and VDE approvals. BK/S500-V-630-R carries BSI, CCC, CSA, cULus, IMQ, SEMKO, and VDE approvals. 0217.630MXEP carries CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE approvals. Selection should be based on required regulatory compliance for the target application.

Q: Can 0217.630MXEP be used in applications requiring -55°C operation?

A: Yes. The 0217.630MXEP specifies operating temperature range of -55°C ~ 125°C. The BK/GDB-V-630MA and BK/S500-V-630-R do not specify operating temperature limits. If extended low-temperature operation is required, 0217.630MXEP is the appropriate selection.

Q: What is the significance of the melting I²t difference between parts?

A: Melting I²t is a thermal characteristic that defines the energy required to melt the fuse element. BK/GDB-V-630MA and BK/S500-V-630-R both specify 0.35, while 0217.630MXEP specifies 0.41. This variance of 0.06 is within acceptable tolerance for fast-blow cartridge fuses and does not affect substitution eligibility. Both values ensure proper overcurrent protection at the 630 mA rating.

Q: Are all parts RoHS compliant?

A: Yes. BK/GDB-V-630MA is RoHS Compliant. BK/S500-V-630-R is RoHS Compliant. 0217.630MXEP is ROHS3 Compliant. All parts meet RoHS requirements.
