Substitute Part Grouping Explanation

Substitute parts for the SLD13U-017 are qualified based on strict electrical and mechanical parameter equivalence. The substitution criteria are defined by the following key parameters:

• Voltage - Reverse Standoff (Typ): 13V
• Voltage - Breakdown (Min): 14.4V
• Voltage - Clamping (Max) @ Ipp: 21.5V
• Current - Peak Pulse (10/1000µs): 237.2A
• Power - Peak Pulse: 5000W (5kW)
• Unidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature: -55°C ~ 175°C (TJ)

The 5KP13A meets all electrical performance requirements and mechanical specifications, providing direct functional equivalence for circuit protection applications requiring 13V TVS diode performance.

Parameter Comparison

Engineering Selection Recommendations

Both the SLD13U-017 and 5KP13A are Active product status components manufactured by Littelfuse Inc. with identical electrical specifications and mechanical packaging. Selection between these parts may be based on packaging format availability: the SLD13U-017 is supplied in Tape & Reel (TR) format, while the 5KP13A is available in Cut Tape (CT) format. Both components maintain ROHS3 compliance and are suitable for applications requiring AEC-Q101 qualified transient voltage suppression at 13V nominal protection levels.

Frequently Asked Questions (FAQ)

Q: Can the 5KP13A directly replace the SLD13U-017 in circuit applications?

A: Yes. Both components share identical electrical parameters including 13V reverse standoff voltage, 21.5V clamping voltage, 237.2A peak pulse current, and 5000W peak pulse power rating. Both use P600 axial through-hole packaging and operate across the same temperature range (-55°C to 175°C).

Q: What is the difference between the SLD13U-017 and 5KP13A?

A: The primary difference is packaging format. The SLD13U-017 is supplied in Tape & Reel (TR) format, while the 5KP13A is supplied in Cut Tape (CT) format. Electrical and mechanical specifications are identical.

Q: Are both parts suitable for automotive applications?

A: The SLD13U-017 carries AEC-Q101 automotive qualification. The 5KP13A is manufactured by the same supplier with identical specifications and ROHS3 compliance, making it suitable for equivalent applications.

Q: What packaging considerations apply to these parts?

A: Both components use P600 axial through-hole packaging, enabling direct mechanical and electrical interchangeability on printed circuit boards. Packaging format (Tape & Reel versus Cut Tape) affects procurement and assembly processes but not circuit performance.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Compliance profiles are equivalent.
