Littelfuse 0216.630H Ceramic Fuse 630mA 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0216.630H is a 630mA 250VAC ceramic cartridge fuse in 5x20mm form factor, designed for fast-blow protection in AC/DC circuits. This part carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain circuit protection functionality in applications where the original part is no longer available or when alternative sourcing is required for production continuity.

Substitute Part Grouping Explanation

Substitution validity for the 0216.630H is determined by strict equivalence across the following parameters: current rating (630mA), voltage rating (250V AC), fuse type (ceramic cartridge), package dimensions (5x20mm), response time (fast blow), breaking capacity (1.5kA), and mounting requirement (holder-based). All substitute parts listed maintain these core electrical and mechanical specifications. Differences in melting I²t values, DC cold resistance, and RoHS compliance status do not disqualify substitution but indicate manufacturing variations within acceptable tolerances for this fuse category.

Engineering Selection Recommendations

For direct replacement of the obsolete 0216.630H, the Littelfuse parametric equivalents (0216.630HXP, 0216.630MXBP, 0216.630MXP, 0216.630TXP, 0216.630VXP) are the primary selection path. These parts maintain identical electrical specifications and are active products with ROHS3 compliance, supporting modern regulatory requirements.

Cross-manufacturer substitutes from Eaton (BK/GDA-630MA, BK/S501-630-R, BK1/S501-630-R, GDA-630MA) and Bel Fuse (5HF 630-R) are electrically equivalent and carry active product status with appropriate certifications (CSA, UL, cULus, cURus). The Bel Fuse 5HF 630-R exhibits a minor dimensional variance (5.10mm diameter versus 5.20mm) but remains mechanically compatible within standard fuse holder tolerances.

Selection should prioritize parts with active product status and compliance certifications matching the application's regulatory environment (CCC, CE, CSA, UL, VDE, SEMKO, UR as applicable).

Frequently Asked Questions (FAQ)

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

A: Yes, all listed parts are electrically and mechanically equivalent. They share identical current rating (630mA), voltage rating (250V AC), fuse type (ceramic cartridge), package form factor (5x20mm), response time (fast blow), and breaking capacity (1.5kA). Physical installation in standard 5x20mm fuse holders is compatible across all parts.

Q: What is the difference between the Littelfuse variants (HXP, MXBP, MXP, TXP, VXP)?

A: These designations represent different packaging and manufacturing variants within the Littelfuse 216 series. All maintain identical electrical performance and specifications. Differences are limited to packaging format (bulk versus other configurations) and minor manufacturing process variations that do not affect functional equivalence.

Q: Why do some parts show different melting I²t and DC cold resistance values?

A: Melting I²t and DC cold resistance variations reflect manufacturing tolerances and design differences between manufacturers. These parameters remain within acceptable ranges for 630mA fast-blow ceramic fuses and do not compromise substitution validity. All parts meet the 1.5kA breaking capacity requirement at 250V AC.

Q: Is the Bel Fuse 5HF 630-R suitable as a substitute despite the 5.10mm diameter specification?

A: Yes. The 5.10mm diameter versus 5.20mm specification represents a minor dimensional tolerance variation. Standard 5x20mm fuse holders accommodate this variance without functional impact. The part is electrically and mechanically compatible.

Q: Which substitute should I select for new designs?

A: For new designs, select from active-status parts with ROHS3 compliance and certifications matching your application requirements. Littelfuse parametric equivalents (0216.630HXP, 0216.630MXP, 0216.630TXP, 0216.630VXP) provide direct manufacturer continuity. Cross-manufacturer options (Eaton, Bel Fuse) are valid alternatives with established certifications.

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

A: All substitute parts carry relevant certifications (CCC, CE, CSA, UL, cULus, cURus, VDE, SEMKO, UR). The original 0216.630H is RoHS non-compliant; all active substitutes are ROHS3 compliant or RoHS compliant, supporting modern regulatory requirements. Verify specific certification requirements for your application's target market.
