Bel Fuse Inc. 5HF 1.6 Ceramic Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The Bel Fuse Inc. 5HF 1.6 is a 1.6 A, 250 V AC/DC ceramic cartridge fuse with fast-blow response characteristics, designed for 5mm x 20mm holder-based applications. This part is classified as obsolete, necessitating identification of active equivalent and substitute components that maintain electrical and mechanical compatibility. Substitute parts must match the core electrical parameters (current rating, voltage rating, response time, breaking capacity) and physical dimensions to ensure direct functional replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Current Rating: 1.6 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Mounting Type: Requires Holder (exact match required)

Secondary Compatibility Factors:

• Operating Temperature Range: -55°C to 125°C (minimum requirement)
• Approval Agencies: CCC, CE, CSA, IMQ, PSE, SEMKO, UL (baseline certifications)

All substitute parts listed below satisfy these criteria and are classified as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 5HF 1.6-R (Bel Fuse Inc.)

The 5HF 1.6-R is the direct parametric equivalent to the obsolete 5HF 1.6. Both parts share identical electrical specifications and physical dimensions. The 5HF 1.6-R is active in production and ROHS3 compliant, making it the preferred direct replacement. Certification coverage includes CCC, CE, CSA, cURus, IMQ, PSE, SEMKO, and VDE.

Alternative Substitutes (Holder-Based, Requires Holder Mounting):

Littelfuse 216 series fuses (021601.6HXP, 021601.6MXBP, 021601.6MXP, 021601.6TXP, 021601.6VXP) are electrically and mechanically equivalent. All are active products with ROHS3 compliance and comprehensive certification coverage (CCC, CE, CSA, KC, PSE, SEMKO, UL, VDE). These parts are suitable for direct substitution in holder-based applications.

SCHURTER 0001.1006 (SP 5x20 series) and Eaton S501-1.6-R are functionally equivalent alternatives with active product status and ROHS3 compliance. Both maintain the required electrical parameters and physical dimensions.

Note on 5HFP 1.6-R (Through Hole Variant):

The 5HFP 1.6-R differs in mounting type (Through Hole vs. Requires Holder) and physical dimensions (5.50mm x 21.00mm vs. 5.10mm x 20.00mm). This variant is not suitable for direct substitution in designs requiring holder-based mounting.

Frequently Asked Questions (FAQ)

Q: Can I use 5HFP 1.6-R as a substitute for 5HF 1.6?

A: No. The 5HFP 1.6-R is a through-hole variant with different physical dimensions (5.50mm x 21.00mm) and mounting requirements. It is not compatible with holder-based applications designed for the 5HF 1.6 (5.10mm x 20.00mm, requires holder).

Q: What is the difference between Littelfuse 021601.6HXP, 021601.6MXP, and 021601.6TXP?

A: All three are Littelfuse 216 series ceramic cartridge fuses with identical electrical specifications (1.6 A, 250 V AC, fast-blow, 1.5 kA breaking capacity) and physical dimensions (5mm x 20mm). The letter designations (H, M, T) indicate internal design variations that do not affect electrical performance or compatibility. All are suitable for direct substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Most substitute parts listed are ROHS3 compliant. The Eaton GDA-1.6A does not specify RoHS status in available documentation. The original 5HF 1.6 is RoHS non-compliant. Verify RoHS compliance requirements for your specific application before selection.

Q: What certifications should I verify for my application?

A: The original 5HF 1.6 carries CCC, CE, CSA, IMQ, PSE, SEMKO, and UL certifications. Most substitute parts maintain these certifications with additional coverage (e.g., Littelfuse parts include VDE and KC). Confirm that the selected substitute meets all required certifications for your target market and application.

Q: Can I mix different manufacturers' fuses in the same circuit?

A: Yes, provided all selected parts meet the identical electrical and mechanical specifications (1.6 A, 250 V AC, fast-blow, 1.5 kA breaking capacity, 5mm x 20mm package, holder-based mounting). However, maintain consistency within a single design to simplify inventory and documentation.

Q: What is the significance of melting I²t values?

A: Melting I²t indicates the thermal energy required to melt the fuse element. Variations in this parameter (ranging from 0.748 to 2.1 across listed parts) reflect internal design differences but do not affect substitution eligibility, as all parts maintain the same current rating and response time classification (fast-blow).
