Substitute Part Grouping Explanation

Substitution of the SS-5-5A-AP with the SS-5H-5A-AP is based on the following alignment of critical electrical and mechanical parameters:

Matched Parameters:

• Current Rating: 5 A (identical)
• Voltage Rating - AC: 250 V (identical)
• Response Time: Slow Blow (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial, Box (identical)
• Physical Dimensions: 0.335" L x 0.169" W x 0.329" H / 8.50mm x 4.30mm x 8.35mm (identical)
• Operating Temperature Range: -40°C ~ 125°C (identical)
• Melting I²t: 120 (identical)
• Fuse Type: Board Mount (Cartridge Style Excluded) (identical)

Both parts belong to the Eaton - Electronics Division fuse product line and maintain functional equivalence for board-level circuit protection applications. The substitute part is qualified for direct replacement in applications where the original part is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the SS-5-5A-AP and SS-5H-5A-AP are active production components from Eaton - Electronics Division with full regulatory compliance. The SS-5H-5A-AP offers an enhanced breaking capacity of 100 A compared to the 50 A rating of the SS-5-5A-AP, while maintaining identical electrical and mechanical specifications for circuit protection function. Both parts carry multiple international approval certifications including VDE and CQC compliance. The SS-5H-5A-AP additionally holds ROHS3 compliance status and includes REACH Unaffected designation. Selection between these parts depends on application-specific breaking capacity requirements and regional certification mandates.

Frequently Asked Questions (FAQ)

Q: Can SS-5H-5A-AP replace SS-5-5A-AP in existing designs?

A: Yes. Both parts share identical current rating (5 A), voltage rating (250 V AC), response time (Slow Blow), mounting type (Through Hole), package configuration (Radial, Box), and physical dimensions (8.50mm x 4.30mm x 8.35mm). The electrical and mechanical interfaces are fully compatible.

Q: What is the difference in breaking capacity between these parts?

A: The SS-5-5A-AP has a breaking capacity of 50 A at rated voltage, while the SS-5H-5A-AP has a breaking capacity of 100 A at rated voltage. Both parts operate identically under normal circuit conditions at their 5 A rated current.

Q: Are there differences in regulatory compliance?

A: Both parts hold VDE and CQC certifications. The SS-5H-5A-AP includes additional certifications (KC, PSE, TUV) and carries ROHS3 compliance with REACH Unaffected status, compared to RoHS Compliant status for the SS-5-5A-AP.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts measure 0.335" L x 0.169" W x 0.329" H (8.50mm x 4.30mm x 8.35mm) and are packaged in identical Radial, Box configuration for through-hole PCB mounting.

Q: What is the operating temperature range for both parts?

A: Both the SS-5-5A-AP and SS-5H-5A-AP operate across the temperature range of -40°C to 125°C.
