Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS-5H-1.6A-APH are determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 1.6 A
• Voltage Rating (AC): 300 V
• Response Time: Slow Blow
• Breaking Capacity @ Rated Voltage: 100 A
• Melting I²t: 23
• DC Cold Resistance: 43 Ohms

Mechanical Parameters:

• Mounting Type: Through Hole
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Package / Case: Radial, Box
• Size / Dimension: 0.335" L x 0.169" W x 0.329" H (8.50mm x 4.30mm x 8.35mm)

Compliance Parameters:

• RoHS Status: RoHS Compliant
• Approval Agencies: CQC, cURus, KC, PSE, TUV, VDE
• Operating Temperature Range: -40°C to 125°C

The only allowable variation between the main part and substitutes is packaging format (Tape & Box versus Cut Tape), which does not affect electrical or mechanical performance in circuit operation.

Parameter Comparison

Engineering Selection Recommendations

The SS-5H-1.6A-AP is a direct functional equivalent to the SS-5H-1.6A-APH. Both parts are manufactured by Eaton - Electronics Division within the SS-5H series and maintain identical electrical, mechanical, and thermal specifications. The parts differ only in packaging format: the main part is supplied in Tape & Box format, while the substitute is supplied in Cut Tape format.

Both parts carry Active product status and hold identical regulatory approvals from CQC, cURus, KC, PSE, TUV, and VDE. Both are RoHS Compliant and operate within the same temperature range of -40°C to 125°C.

Selection between these parts should be based on procurement requirements, inventory management practices, and packaging compatibility with assembly equipment. No electrical or mechanical re-qualification is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can SS-5H-1.6A-AP be used as a direct replacement for SS-5H-1.6A-APH in circuit design?

A: Yes. Both parts are electrically and mechanically identical. They share the same current rating (1.6 A), voltage rating (300 V AC), response time (Slow Blow), breaking capacity (100 A), and physical dimensions (0.335" L x 0.169" W x 0.329" H). No circuit redesign or re-qualification is required.

Q: What is the difference between Tape & Box (TB) and Cut Tape (CT) packaging?

A: Tape & Box packaging supplies components on continuous tape within a protective box, suitable for automated pick-and-place assembly. Cut Tape packaging supplies components on tape segments cut to specific lengths, typically for manual assembly or smaller production runs. Both formats contain identical components with no functional differences.

Q: Are the regulatory approvals identical between SS-5H-1.6A-APH and SS-5H-1.6A-AP?

A: Yes. Both parts hold identical approvals from CQC, cURus, KC, PSE, TUV, and VDE. Both are RoHS Compliant and meet the same regulatory requirements.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Yes. Both parts are manufactured by Eaton - Electronics Division within the same series and carry identical electrical specifications, breaking capacity (100 A), melting I²t (23), and DC cold resistance (43 Ohms). They are suitable for equivalent reliability applications.

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

A: Both SS-5H-1.6A-APH and SS-5H-1.6A-AP operate across the same temperature range of -40°C to 125°C.

Q: Are there any mechanical compatibility issues when substituting between these parts?

A: No. Both parts are through-hole mounted radial fuses with identical physical dimensions (8.50mm x 4.30mm x 8.35mm). They fit the same PCB footprints and mounting positions without modification.
