Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/S500-V-2-R is determined by strict alignment of the following parameters:

Primary Substitution Criteria:

• Current Rating: 2 A (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)

Secondary Compliance Criteria:

• RoHS Status: RoHS Compliant or ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited) or Not Applicable
• ECCN: EAR99 (consistent export classification)
• HTSUS: 8536.10.0020 (consistent tariff classification)

All identified substitute parts meet these criteria. Variations in Breaking Capacity, Melting I²t, DC Cold Resistance, and dimensional tolerances within the specified package envelope do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are classified as Active product status and maintain RoHS compliance or ROHS3 compliance, confirming current manufacturing support and environmental regulatory alignment.

BK/GMA-V-2-R (Eaton - Electronics Division): Parametric equivalent manufactured by the same supplier as the original part. Shares identical electrical ratings and package dimensions. Breaking Capacity is elevated to 100 A compared to the original 35 A specification. Melting I²t is reduced to 3.1 from 4.2. Approval agencies include CSA, PSE, and UL. This part is suitable for direct substitution where the higher breaking capacity does not create circuit design conflicts.

0034.1519.PT (SCHURTER Inc.): Direct manufacturer equivalent with matching current, voltage, and fuse type specifications. Breaking Capacity and Melting I²t align with the original part at 35 A and 5.28 respectively. Dimensional tolerance is 5.40mm x 22.50mm, representing a minor variation within the 5mm x 20mm package envelope. Approval agencies include cURus. Operating temperature range is specified as -55°C ~ 125°C. ROHS3 Compliant status confirms current production standards.

0217002.MXEP (Littelfuse Inc.): Similar manufacturer equivalent with matching electrical specifications. Breaking Capacity is 35 A. Melting I²t is 5.73. Dimensional tolerance is 5.80mm x 22.50mm. Approval agencies include BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, and VDE, representing the broadest regulatory coverage among substitute options. Operating temperature range is -55°C ~ 125°C. ROHS3 Compliant and REACH Unaffected status confirms compliance with current environmental standards.

5SFP 2-R (Bel Fuse Inc.): Similar manufacturer equivalent with matching electrical specifications. Breaking Capacity is 35 A. Melting I²t is 6.4, the highest among all options. Dimensional tolerance is 5.50mm x 21.00mm, closest to the original specification. Approval agencies include CCC, CE, CSA, cULus, IMQ, SEMKO, and VDE. Operating temperature range is -55°C ~ 125°C. ROHS3 Compliant and REACH Unaffected status confirms compliance with current environmental standards.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the BK/S500-V-2-R?

A: Substitution eligibility requires exact matching of current rating (2 A), voltage rating (250 V AC), fuse type (Cartridge, Glass), response time (Fast Blow), package dimensions (5mm x 20mm Axial), and mounting type (Through Hole). All identified substitute parts meet these criteria.

Q: Are there differences in Breaking Capacity among the substitute parts?

A: Yes. The BK/GMA-V-2-R has a Breaking Capacity of 100 A, while the original BK/S500-V-2-R and all other substitutes are rated at 35 A. Breaking Capacity does not disqualify substitution but should be verified against circuit design requirements.

Q: How do Melting I²t values differ, and does this affect substitution?

A: Melting I²t values range from 3.1 (BK/GMA-V-2-R) to 6.4 (5SFP 2-R). These variations reflect different thermal response characteristics within the fast-blow classification. Substitution is valid across all options; however, circuit protection coordination should be verified if the application has specific I²t requirements.

Q: What is the significance of dimensional tolerances in the 5mm x 20mm package?

A: All substitute parts are specified as 5mm x 20mm (Axial) package type. Actual dimensions vary slightly: SCHURTER 0034.1519.PT is 5.40mm x 22.50mm, Littelfuse 0217002.MXEP is 5.80mm x 22.50mm, and Bel Fuse 5SFP 2-R is 5.50mm x 21.00mm. These tolerances are within acceptable mechanical compatibility for standard through-hole fuse holders designed for the 5x20 envelope.

Q: Which substitute part has the broadest regulatory approval coverage?

A: The Littelfuse 0217002.MXEP includes approval from BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, and VDE, representing the most comprehensive regulatory certification among all substitute options.

Q: Are all substitute parts currently in active production?

A: Yes. All identified substitute parts are classified as Active product status, confirming current manufacturing support and availability.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: Both designations confirm compliance with hazardous substance restrictions. ROHS3 Compliant indicates compliance with the most current RoHS 3 directive. All substitute parts meet current environmental regulatory requirements.

Q: Can the BK/GMA-V-2-R be used as a direct replacement despite its higher Breaking Capacity?

A: The BK/GMA-V-2-R meets all primary substitution criteria and is manufactured by the same supplier as the original part. The elevated Breaking Capacity of 100 A does not prevent substitution; however, circuit design verification is recommended to ensure the higher breaking capacity does not introduce unintended protection characteristics.

Q: Which substitute part most closely matches the original BK/S500-V-2-R dimensions?

A: The Bel Fuse 5SFP 2-R has dimensions of 5.50mm x 21.00mm, which most closely approximates the original specification of 5.54mm x 21.10mm.

Q: Are operating temperature ranges specified for all parts?

A: The original BK/S500-V-2-R does not specify an operating temperature range. Three substitute parts (SCHURTER 0034.1519.PT, Littelfuse 0217002.MXEP, and Bel Fuse 5SFP 2-R) specify -55°C ~ 125°C operating temperature range. The BK/GMA-V-2-R does not specify an operating temperature range.
