Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Matching Parameters:

Current Rating: 1 A (exact match required)
Voltage Rating (AC): 250 V (exact match required)
Package / Case: 5mm x 20mm (exact match required)
Fuse Type: Cartridge, Ceramic (exact match required)
Response Time: Fast Blow (exact match required)
Breaking Capacity @ Rated Voltage: 1.5kA (exact match required)

Secondary Considerations:

Approval Agency certifications (CCC, CE, CSA, KC, PSE, SEMKO, UL, VDE)
RoHS compliance status
Operating temperature range compatibility
DC Cold Resistance (where applicable)

All substitute parts listed below meet the primary matching parameters and are therefore electrically and mechanically interchangeable with the main part.

Engineering Selection Recommendations

Littelfuse Variants (0216001.MXP, 0216001.VXP): These parts are parametric equivalents from the same manufacturer and series. 0216001.MXP offers the highest inventory availability (13100 units) while maintaining identical electrical specifications and ROHS3 compliance.

SCHURTER 0001.1004: Direct manufacturer equivalent with identical electrical ratings and mechanical dimensions. ROHS3 compliant. Melting I²t value of 0.75 differs from the main part but remains within the fast-blow response category. Suitable for applications requiring SCHURTER certification.

Eaton S501 Series (BK/S501-1-R, BK1/S501-1-R, S501-1-R): MFR recommended substitutes with ROHS3 compliance (except BK/GDA-1A). All S501 variants meet electrical and mechanical requirements. BK1/S501-1-R offers highest inventory (2800 units) among Eaton options.

Eaton BK/GDA-1A: MFR recommended substitute with identical electrical ratings. Note: RoHS non-compliant status. Suitable only for applications where RoHS compliance is not required.

OptiFuse FCD-1A: Parametric equivalent with ROHS3 compliance and IEC 60127 certification. Melting I²t of 0.2019 maintains fast-blow characteristics. Suitable for applications requiring IEC certification.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts directly in place of the 0216001.MXGP?

A: Yes. All listed substitute parts match the critical electrical parameters (1A, 250VAC, 5x20mm, 1.5kA breaking capacity, fast-blow response) and mechanical dimensions. They are mechanically and electrically interchangeable. Verify that your application's certification requirements align with the substitute part's approval agencies.

Q: What is the difference between the Littelfuse variants (0216001.MXGP, 0216001.MXP, 0216001.VXP)?

A: All three are from Littelfuse Series 216 with identical electrical and mechanical specifications. The differences are in packaging designation and inventory levels. 0216001.MXP has the highest stock availability.

Q: Why does the SCHURTER 0001.1004 have a different Melting I²t value (0.75 vs 0.18)?

A: Melting I²t represents the thermal energy required to melt the fuse element. Despite the different value, both parts maintain the same 1A current rating, 250VAC voltage rating, and fast-blow response time, making them functionally equivalent for circuit protection purposes.

Q: Should I use the BK/GDA-1A if my application requires RoHS compliance?

A: No. BK/GDA-1A is RoHS non-compliant. Use ROHS3-compliant alternatives such as BK/S501-1-R, BK1/S501-1-R, S501-1-R, FCD-1A, or the Littelfuse variants instead.

Q: Which substitute offers the best inventory availability?

A: 0216001.MXP (Littelfuse) has 13100 units in stock, followed by BK1/S501-1-R (Eaton) with 2800 units.

Q: Are there any approval agency differences I should consider?

A: All parts carry multiple certifications (CCC, CE, CSA, KC, PSE, SEMKO, UL, VDE). Verify that the substitute part's certification list includes all agencies required by your application or regional standards.
