Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5HFP 630 is determined by the following critical parameters:

• Current Rating: 630 mA (exact match required for direct substitution)
• Voltage Rating: 250 V AC minimum
• Fuse Type: Ceramic cartridge with fast-blow characteristics
• Package / Case: 5mm x 20mm form factor
• Mounting Type: Through-hole configuration
• Breaking Capacity: 1.5 kA minimum

Parts meeting all these criteria are classified as direct equivalents. Parts with identical electrical specifications but different mounting requirements or form factors are classified as functional alternatives requiring mechanical adaptation.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred):

The 5HFP 630-R from Bel Fuse Inc. is the primary direct equivalent. It maintains identical electrical specifications (630 mA, 250 V AC, fast-blow ceramic cartridge) and mechanical form factor (5mm x 20mm through-hole). The 5HFP 630-R is active in production with ROHS3 compliance and expanded certification coverage (cULus), making it the recommended replacement for the obsolete 5HFP 630.

Cross-Manufacturer Equivalent:

The 0216.630MXEP from Littelfuse provides equivalent electrical performance with identical current rating, voltage, and response characteristics. This part maintains the 5mm x 20mm through-hole configuration and meets all critical electrical parameters. The 0216.630MXEP carries broader international certifications (SEMKO, UR, VDE) and ROHS3 compliance. Physical dimensions vary slightly (6.00mm diameter vs. 5.50mm), requiring verification of mechanical fit within the application.

Functional Alternative (Higher Current Rating):

The 5HF 800-R from Bel Fuse Inc. provides 800 mA protection versus the 630 mA specification. This part requires a separate fuse holder for mounting, differing from the through-hole configuration of the original part. Selection of this alternative is appropriate only when circuit protection requirements permit the higher current rating and mechanical adaptation is feasible.

Frequently Asked Questions (FAQ)

Q: Can the 5HFP 630-R be used as a direct replacement for the 5HFP 630?

A: Yes. The 5HFP 630-R maintains identical electrical specifications (630 mA, 250 V AC/DC, fast-blow response) and mechanical form factor (5mm x 20mm through-hole). Both parts are ceramic cartridge fuses with 1.5 kA breaking capacity and -55°C to 125°C operating range. The primary difference is product status: the 5HFP 630-R is active in production with ROHS3 compliance.

Q: What are the differences between the 5HFP 630-R and 0216.630MXEP?

A: Both parts share identical electrical specifications and current ratings (630 mA, 250 V AC, fast-blow ceramic). The 0216.630MXEP has slightly larger physical dimensions (6.00mm diameter x 22.50mm length versus 5.50mm x 21.00mm) and different DC cold resistance (0.465 Ohms versus 0.286 Ohms). The 0216.630MXEP carries additional international certifications (SEMKO, UR, VDE). Mechanical fit verification is required before substitution.

Q: When should the 5HF 800-R be considered?

A: The 5HF 800-R is a functional alternative only when circuit protection requirements permit 800 mA operation instead of 630 mA. This part requires a separate fuse holder for mounting, unlike the through-hole configuration of the original 5HFP 630. Mechanical adaptation and circuit analysis are necessary before selection.

Q: Are all substitute parts RoHS compliant?

A: The 5HFP 630 is RoHS non-compliant. All substitute parts listed (5HFP 630-R, 0216.630MXEP, and 5HF 800-R) are ROHS3 compliant. Applications requiring RoHS compliance must use one of the substitute parts.

Q: What certifications apply to each part?

A: The 5HFP 630 carries CCC, CE, CSA, and UL certifications. The 5HFP 630-R adds cULus certification. The 0216.630MXEP includes CCC, CE, CSA, SEMKO, UR, and VDE certifications. The 5HF 800-R carries CCC, CE, CSA, and cURus certifications. Application-specific certification requirements should be verified before final part selection.
