Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5HT 630-R is determined by the following critical parameters:

• Current Rating: 630 mA (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: Slow Blow (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)

Substitute parts are classified into two categories:

Parametric Equivalent: 5HTP 630-R (Bel Fuse Inc.) — Identical electrical and mechanical specifications with matching series designation variation.

Similar Parts: 0001.2502 (SCHURTER Inc.) and 0215.630HXP (Littelfuse Inc.) — Match all critical parameters with minor variations in secondary specifications such as DC voltage rating, breaking capacity, or melting I²t values.

Parameter Comparison

Engineering Selection Recommendations

5HTP 630-R (Bel Fuse Inc.) is the primary parametric equivalent, offering identical electrical specifications, melting I²t characteristics, and regulatory certifications (CCC, CE, CSA, cULus). This part is recommended for direct replacement where Bel Fuse series continuity is required.

0215.630HXP (Littelfuse Inc.) provides full compatibility with all critical parameters and maintains active product status. This part carries broader regulatory approval (CE, CSA, SEMKO, UL, VDE) and is suitable for applications requiring multi-standard compliance. The melting I²t value of 0.635 represents a minor variation from the primary part specification.

0001.2502 (SCHURTER Inc.) meets all critical electrical and mechanical requirements with the addition of 300 V DC voltage rating capability. This part is suitable for applications with dual AC/DC voltage requirements. Regulatory approvals (cURus, VDE) differ from the primary part and should be verified against application-specific compliance mandates.

All substitute parts maintain ROHS3 compliance, identical operating temperature ranges, and equivalent mechanical form factors. Selection should prioritize regulatory certification alignment with end-application requirements.

Frequently Asked Questions (FAQ)

Q: Can 5HTP 630-R replace 5HT 630-R in all applications?

A: Yes. Both parts are manufactured by Bel Fuse Inc. with identical electrical ratings (630 mA, 250 V AC), response time (slow blow), package dimensions (5mm x 20mm), and regulatory certifications. The series designation variation (5HTP vs. 5HT) reflects internal product line differentiation without affecting functional compatibility.

Q: What is the difference between the Littelfuse 0215.630HXP and the primary 5HT 630-R?

A: The 0215.630HXP matches all critical parameters: 630 mA current rating, 250 V AC voltage, 5mm x 20mm package, and slow-blow response. Minor differences include melting I²t (0.635 vs. 0.7) and DC cold resistance (0.72 vs. 0.63 Ohms). Regulatory certifications differ (Littelfuse includes UL and SEMKO; Bel Fuse includes CCC). Both are ROHS3 compliant and active products.

Q: Is the SCHURTER 0001.2502 suitable for DC applications?

A: The 0001.2502 is rated for 300 V DC, providing capability beyond the primary 5HT 630-R specification. However, the primary part does not specify DC voltage rating. Use the SCHURTER part only if your application explicitly requires DC voltage protection at 300 V or lower. Verify that your circuit protection requirements align with this extended DC rating.

Q: Do all substitute parts require the same holder?

A: All substitute parts share the identical 5mm x 20mm package dimension and cartridge ceramic form factor, requiring the same holder type. Mechanical compatibility is assured across all listed substitutes.

Q: Which substitute part has the broadest regulatory approval?

A: The Littelfuse 0215.630HXP carries the most comprehensive regulatory certifications: CE, CSA, SEMKO, UL, and VDE. This part is recommended for applications requiring multi-standard compliance across North American and European markets.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are: 5HT 630-R (1853 units), 5HTP 630-R (1639 units), 0001.2502 (1411 units), and 0215.630HXP (647 units). Availability may influence selection timing for high-volume procurement.
