Engineering Selection Recommendations

Littelfuse Series 216 (0216.630HXP, 0216.630MXP, 0216.630TXP): These parts maintain identical electrical specifications and thermal characteristics to the primary part. All three carry full compliance with CCC, CE, CSA, SEMKO, UR, and VDE standards. Selection among these variants depends on supply availability and regional sourcing requirements. All are ROHS3 compliant.

SCHURTER 0001.1002 (Series SP 5x20): This part meets all primary substitution criteria with CCC, cURus, KC, and VDE approvals. The melting I²t value of 0.207 is slightly elevated compared to the Littelfuse reference, indicating marginally slower thermal response. ROHS3 compliant. Suitable for applications where SCHURTER supply chain integration is preferred.

Bel Fuse 5HF 630-R (Series 5HF): Meets all electrical and mechanical requirements with CCC, CE, CSA, and cULus approvals. Physical dimensions are 5.10mm diameter versus 5.20mm for the reference part, representing a minor tolerance variation within standard holder compatibility. Melting I²t of 0.29 indicates slower thermal response. ROHS3 compliant.

Eaton GDA Series (BK/GDA-630MA, GDA-630MA): Both parts meet electrical specifications with CSA and UR approvals. Melting I²t of 0.064 indicates faster thermal response than the reference part. Operating temperature range not specified in documentation. RoHS compliant (GDA-630MA status not specified; BK/GDA-630MA is RoHS compliant).

Eaton S501 Series (BK/S501-630-R, BK1/S501-630-R): Both parts meet electrical specifications with CSA and cULus/cURus approvals. Melting I²t of 0.064 indicates faster thermal response. Operating temperature range not specified. ROHS3 compliant. BK1/S501-630-R offers highest inventory availability at 1963 units.

OptiFuse FCD-630MA (Series FCD): Meets all electrical and mechanical requirements with IEC 60127 approval. Includes explicit 250 V DC rating in addition to 250 V AC. Melting I²t of 0.0672 indicates faster thermal response. ROHS3 compliant. Highest inventory availability at 3827 units.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the 0216.630MXBP?

A: Yes. All listed substitute parts share identical current rating (630 mA), voltage rating (250 V AC), package dimensions (5mm x 20mm), response time (fast blow), and breaking capacity (1.5 kA). They are mechanically and electrically interchangeable in standard 5x20mm fuse holders without circuit modification.

Q: What is the significance of different Melting I²t values?

A: Melting I²t indicates the thermal energy required to melt the fuse element. Lower values (0.064 for Eaton parts, 0.0672 for OptiFuse) represent faster thermal response. Higher values (0.175 for Littelfuse, 0.207 for SCHURTER, 0.29 for Bel Fuse) represent slower thermal response. All values are within the 630 mA fast-blow classification and are suitable for the same circuit protection applications.

Q: Are all substitute parts RoHS compliant?

A: Most substitute parts are ROHS3 compliant. Eaton GDA-630MA and BK/GDA-630MA are RoHS compliant. OptiFuse FCD-630MA is ROHS3 compliant. Verify specific RoHS certification requirements for your application region.

Q: Which substitute part has the best inventory availability?

A: OptiFuse FCD-630MA offers the highest inventory at 3827 units. Among Littelfuse variants, 0216.630HXP has 1190 units available. Among Eaton parts, BK1/S501-630-R has 1963 units available.

Q: Do all substitute parts support the full -55°C to 125°C operating temperature range?

A: Littelfuse (0216.630HXP, 0216.630MXP, 0216.630TXP), SCHURTER 0001.1002, Bel Fuse 5HF 630-R, and OptiFuse FCD-630MA all specify -55°C to 125°C operation. Eaton parts (BK/GDA-630MA, BK/S501-630-R, BK1/S501-630-R, GDA-630MA) do not specify operating temperature range in provided documentation.

Q: What approval agencies are represented across all substitute parts?

A: Common approvals include CCC, CE, CSA, and UR. Littelfuse and Bel Fuse include SEMKO and VDE. SCHURTER includes KC and cURus. Eaton includes cULus/cURus. OptiFuse is certified to IEC 60127. Verify specific regional compliance requirements for your application.

Q: Can I mix different substitute parts in the same equipment?

A: Yes, all substitute parts meet identical electrical and mechanical specifications and can be used together in multi-fuse applications. However, for consistency in thermal response characteristics, consider sourcing from a single manufacturer variant if thermal coordination is critical to circuit design.
