Littelfuse 0215.630H Ceramic Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0215.630H is a 630 mA, 250 V AC ceramic cartridge fuse in 5mm x 20mm form factor with slow-blow response characteristics. This part is classified as obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs. The fuse requires a compatible holder for installation and is designed for applications requiring reliable overcurrent protection in AC circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0215.630H is determined by strict equivalence across the following parameters:

• Current Rating: 630 mA (exact match required)
• Voltage Rating (AC): 250 V (minimum requirement)
• Fuse Type: Cartridge, Ceramic
• Package / Case: 5mm x 20mm (physical compatibility with existing holders)
• Response Time: Slow Blow
• Operating Temperature Range: -55°C ~ 125°C (or compatible subset)

All identified substitutes maintain these core electrical and mechanical specifications. Variations in secondary parameters such as breaking capacity, melting I²t, DC cold resistance, and approval agencies do not affect functional substitutability within the defined scope.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (0215.630HXP, 0001.2502, 5HT 630-R) are functionally equivalent to the 0215.630H based on core electrical and mechanical parameters. Selection should prioritize active product status and regulatory compliance:

0215.630HXP (Littelfuse Inc.) maintains manufacturer continuity with the original part. It carries active product status, ROHS3 compliance, and expanded approval certifications (CE, SEMKO, VDE in addition to CSA and UL). This part is the direct manufacturer upgrade path.

0001.2502 (SCHURTER Inc.) provides an alternative from an established fuse manufacturer. It offers the additional benefit of 300 V DC voltage rating, extending application scope beyond AC-only circuits. ROHS3 compliance and cURus/VDE certifications are provided.

5HT 630-R (Bel Fuse Inc.) is an active product with comprehensive international certifications (CCC, CE, CSA, cULus) and ROHS3 compliance. Physical dimensions show a minor variation (5.10mm diameter versus 5.20mm), which remains within standard holder tolerances for 5mm x 20mm form factor compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitutes directly in place of the 0215.630H?

A: Yes. All three substitutes maintain the same current rating (630 mA), AC voltage rating (250 V), fuse type (ceramic cartridge), package dimensions (5mm x 20mm), and response time (slow blow). Physical compatibility with existing 5mm x 20mm fuse holders is confirmed.

Q: What is the difference between the main part and its substitutes?

A: The primary difference is product status. The 0215.630H is obsolete; all substitutes are active products. Secondary differences include RoHS compliance status (substitutes are ROHS3 compliant), expanded approval certifications, and minor variations in electrical characteristics such as melting I²t and DC cold resistance. These variations do not affect substitutability for AC applications.

Q: Does the 0001.2502 offer any advantage over the other substitutes?

A: The 0001.2502 includes a 300 V DC voltage rating in addition to the 250 V AC rating. This makes it suitable for both AC and DC circuit protection applications, whereas the other substitutes are specified for AC circuits. If your application requires DC protection capability, this part provides extended functionality.

Q: Are there any compliance or certification differences I should consider?

A: All substitutes carry ROHS3 compliance and multiple international certifications. The 0215.630HXP offers the broadest certification set (CE, SEMKO, VDE, CSA, UL). The 5HT 630-R includes CCC certification, relevant for certain markets. Selection should align with your specific regulatory requirements.

Q: Will the physical dimensions of the 5HT 630-R (5.10mm diameter) cause compatibility issues?

A: No. The 5.10mm diameter of the 5HT 630-R falls within standard tolerance ranges for 5mm x 20mm fuse holders. Physical compatibility is maintained across all substitutes.
