Substitute Part Grouping Explanation

Substitute parts for the SS-5H-3.15A-AP are identified based on strict equivalence of the following critical parameters:

• Current Rating: 3.15 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
• Package / Case: Radial, Box (exact match required)
• Physical Dimensions: 0.335" L x 0.169" W x 0.329" H / 8.50mm x 4.30mm x 8.35mm (exact match required)
• Operating Temperature Range: -40°C ~ 125°C (exact match required)
• Melting I²t: 67 (exact match required)

The SS-5-3.15A-AP meets all critical parameter requirements for substitution. Differences in breaking capacity and DC cold resistance do not disqualify this part from substitution, as these parameters fall within acceptable tolerance ranges for board mount fuse applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SS-5H-3.15A-AP and SS-5-3.15A-AP are active production parts from Eaton - Electronics Division with full RoHS compliance. Selection between these parts is based on the following criteria:

SS-5H-3.15A-AP is specified when breaking capacity of 100 A at rated voltage is required for the application circuit protection design.

SS-5-3.15A-AP is specified when breaking capacity of 35 A at rated voltage is sufficient for the application circuit protection design. This part offers higher inventory availability (2100 Pcs vs. 1045 Pcs) and is suitable for applications with lower fault current levels.

Both parts carry equivalent international safety certifications including CQC, VDE, and TUV approvals. The choice between these parts depends solely on the breaking capacity requirement of the specific circuit protection application.

Frequently Asked Questions (FAQ)

Q: Can SS-5-3.15A-AP be used as a direct replacement for SS-5H-3.15A-AP?

A: Yes, for applications where the breaking capacity requirement is 35 A or lower. Both parts share identical current rating (3.15 A), voltage rating (250 V AC), response time (Slow Blow), mounting type (Through Hole), package configuration (Radial, Box), and physical dimensions. The primary difference is breaking capacity at rated voltage.

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

A: Breaking capacity defines the maximum fault current the fuse can safely interrupt without rupturing or creating a hazard. The SS-5H-3.15A-AP has a breaking capacity of 100 A, while the SS-5-3.15A-AP has 35 A. Selection depends on the maximum prospective fault current in the circuit being protected.

Q: Are the physical dimensions identical between these parts?

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 use identical radial, box package configuration. They are mechanically interchangeable in through-hole PCB mounting applications.

Q: Do both parts meet the same safety certifications?

A: Both parts are RoHS compliant and carry international safety approvals. The SS-5H-3.15A-AP carries CQC, cURus, KC, PSE, TUV, and VDE certifications. The SS-5-3.15A-AP carries CQC, cULus, EK-MARK, SEMKO, and VDE certifications. Both meet the required safety standards for board mount fuse applications.

Q: What does the melting I²t value of 67 represent?

A: Melting I²t is a thermal characteristic that defines the energy required to melt the fuse element. Both parts share an identical melting I²t value of 67, indicating equivalent thermal response characteristics and slow blow behavior.

Q: Can these parts be used in DC applications?

A: Yes. Both parts are rated for 250 V AC/DC operation and are suitable for direct current applications within the specified voltage and current parameters.
