Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS-5H-5A-BKH is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 5 A
• Voltage Rating - AC: 300 V
• Response Time: Slow Blow
• Mounting Type: Through Hole
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Package / Case: Radial, Box
• Breaking Capacity @ Rated Voltage: 100 A
• Melting I²t: 120
• Operating Temperature Range: -40°C ~ 125°C
• Size / Dimension: 0.335" L x 0.170" W x 0.337" H (8.50mm x 4.30mm x 8.55mm)
• DC Cold Resistance: 7.35 mOhms

The SS-5H-5A-BK qualifies as a parametric equivalent because it matches all mandatory electrical and mechanical specifications. Differences in RoHS compliance status do not affect functional substitution capability.

Engineering Selection Recommendations

SS-5H-5A-BK Selection Criteria:

The SS-5H-5A-BK is a direct parametric equivalent to the SS-5H-5A-BKH across all electrical and mechanical specifications. Selection of the SS-5H-5A-BK is appropriate when:

1. RoHS3 Compliance Required: The SS-5H-5A-BK meets ROHS3 compliance requirements, whereas the SS-5H-5A-BKH is RoHS non-compliant. Applications subject to RoHS3 regulations must use the SS-5H-5A-BK.

2. Inventory Availability: The SS-5H-5A-BK maintains higher inventory levels (2564 pieces) compared to the SS-5H-5A-BKH (808 pieces), supporting supply chain continuity for high-volume production.

3. Regulatory Certification: Both parts carry identical approval certifications (CQC, cURus, KC, PSE, TUV, VDE), confirming equivalent safety and performance standards.

4. Circuit Protection Function: Both parts deliver identical circuit protection performance with 5 A current rating, 300 V AC voltage rating, slow blow response, and 100 A breaking capacity.

Frequently Asked Questions (FAQ)

Q: Can SS-5H-5A-BK replace SS-5H-5A-BKH in all applications?

A: The SS-5H-5A-BK is a parametric equivalent and can replace the SS-5H-5A-BKH in applications where RoHS3 compliance is not a constraint. Both parts are electrically and mechanically identical. If the application requires RoHS non-compliant components, the SS-5H-5A-BKH must be used.

Q: What is the difference between SS-5H-5A-BKH and SS-5H-5A-BK?

A: The primary difference is RoHS compliance status. The SS-5H-5A-BKH is RoHS non-compliant, while the SS-5H-5A-BK is ROHS3 compliant. All electrical parameters, mechanical dimensions, thermal ratings, and breaking capacity are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.335" L x 0.170" W x 0.337" H (8.50mm x 4.30mm x 8.55mm) and use the same radial, box package configuration for through hole mounting.

Q: Do both parts have the same approval certifications?

A: Yes. Both the SS-5H-5A-BKH and SS-5H-5A-BK carry identical regulatory approvals: CQC, cURus, KC, PSE, TUV, and VDE.

Q: What is the melting I²t value, and does it differ between parts?

A: The melting I²t value is 120 for both parts. This parameter is identical and indicates equivalent thermal response characteristics.

Q: Can these fuses be used in DC applications?

A: Both parts are rated for 300 V AC/DC operation. The DC cold resistance is 7.35 mOhms for both parts, confirming equivalent DC performance.

Q: What is the operating temperature range?

A: Both parts operate across the identical temperature range of -40°C to 125°C, supporting equivalent thermal performance in diverse environmental conditions.
