Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5HF 1.6-R is determined by strict equivalence across the following critical parameters: current rating (1.6 A), voltage rating (250 V AC), fuse type (ceramic cartridge), package dimensions (5mm x 20mm), response time (fast blow), and breaking capacity (1.5 kA). All substitute parts listed maintain identical values for these parameters, ensuring direct functional interchangeability without circuit modification or performance degradation. Secondary parameters including melting I²t, DC cold resistance, and approval agency certifications are provided for engineering reference but do not restrict substitution eligibility. All substitute parts are active products with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing status and full inventory availability. Selection among equivalent parts may be based on regional certification requirements and approval agency coverage. The 5HF 1.6-R (Bel Fuse) carries certifications from CCC, CE, CSA, cURus, IMQ, PSE, SEMKO, and VDE. The 021601.6HXP and 021601.6MXP (Littelfuse) provide the broadest certification coverage including CCC, CE, CSA, KC, PSE, SEMKO, UL, and VDE. The 0001.1006 (SCHURTER) supports CCC, cURus, KC, PSE/JET, and VDE certifications. The GDA-1.6A (Eaton) carries CCC, SEMKO, and UR certifications. Component selection should align with the specific regulatory requirements of the target application and geographic market. All parts maintain ROHS3 compliance and REACH unaffected status where specified.

Frequently Asked Questions (FAQ)

Q: Can the 021601.6HXP and 021601.6MXP be used interchangeably with the 5HF 1.6-R?

A: Yes. Both Littelfuse parts are direct functional equivalents. They share identical current rating (1.6 A), voltage rating (250 V AC), ceramic cartridge construction, 5mm x 20mm package dimensions, fast-blow response, and 1.5 kA breaking capacity. Both are active products with current inventory.

Q: What is the significance of the melting I²t values shown in the comparison table?

A: Melting I²t is a secondary thermal characteristic that describes the fuse element's energy absorption capacity. While the substitute parts display different I²t values (ranging from 0.748 to 2.1), all parts meet the same current rating and breaking capacity specifications. These variations do not affect substitution eligibility for applications designed around the 1.6 A, 250 V specification.

Q: Are there differences in DC cold resistance among the substitute parts?

A: DC cold resistance values vary across manufacturers (0.072 to 0.1112 Ohms). These differences are within acceptable engineering tolerances for ceramic cartridge fuses and do not restrict substitution. The 5HF 1.6-R exhibits the lowest resistance at 0.072 Ohms, while Littelfuse parts measure 0.1112 Ohms and Eaton measures 0.113 Ohms.

Q: Which substitute part has the best certification coverage?

A: The 021601.6HXP and 021601.6MXP (Littelfuse Series 216) provide the most comprehensive certification portfolio, including CCC, CE, CSA, KC, PSE, SEMKO, UL, and VDE. These certifications support the widest range of global markets and regulatory frameworks.

Q: Can I substitute the GDA-1.6A (Eaton) if my application requires UL certification?

A: No. The GDA-1.6A carries CCC, SEMKO, and UR certifications but does not include UL certification. For UL-certified applications, select the 021601.6HXP or 021601.6MXP (Littelfuse), which both carry UL approval.

Q: Is the operating temperature range identical across all substitute parts?

A: The 5HF 1.6-R, 0001.1006, 021601.6HXP, and 021601.6MXP all specify -55°C ~ 125°C operating temperature. The GDA-1.6A does not provide an operating temperature specification in the available data.

Q: What inventory levels are available for each part?

A: Current inventory includes 5HF 1.6-R (1,687 pcs), 021601.6MXP (1,799 pcs), 0001.1006 (1,223 pcs), 021601.6HXP (1,106 pcs), and GDA-1.6A (883 pcs). All parts are in stock as new original components.
