Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLD17U-017 are qualified based on the following critical parameters that must remain equivalent:

• Voltage - Reverse Standoff (Typ): 17V
• Voltage - Breakdown (Min): 18.9V
• Voltage - Clamping (Max) @ Ipp: 27.6V
• Current - Peak Pulse (10/1000µs): 184.8A
• Power - Peak Pulse: 5000W
• Unidirectional Channels: 1
• Package / Case: P600, Axial
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 175°C

The 5KP17A meets all electrical and mechanical requirements for direct substitution. Both parts are manufactured by Littelfuse Inc., share identical voltage and current ratings, and are housed in the same P600 axial package. The primary difference is packaging format: SLD17U-017 is supplied in Tape & Reel (TR), while 5KP17A is available in Cut Tape (CT). Both maintain RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Parameter Comparison

Engineering Selection Recommendations

The 5KP17A is a direct electrical and mechanical equivalent to the SLD17U-017. Both parts are actively produced by Littelfuse Inc. and carry identical electrical specifications across all critical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and power dissipation. Both are AEC-Q101 qualified for automotive applications and RoHS3 compliant.

Selection between these parts should be based on packaging and supply chain requirements. The SLD17U-017 is supplied in Tape & Reel format, suitable for automated assembly processes. The 5KP17A is supplied in Cut Tape format, appropriate for manual or semi-automated handling. Both parts are housed in the P600 axial package and are pin-compatible for through-hole mounting.

Current inventory status shows 658 units of SLD17U-017 and 3600 units of 5KP17A available as new original stock.

Frequently Asked Questions (FAQ)

Q: Can the 5KP17A be used as a direct replacement for the SLD17U-017?

A: Yes. Both parts are identical in electrical performance and mechanical compatibility. They share the same voltage ratings (17V reverse standoff, 27.6V clamping), current handling (184.8A peak pulse), power dissipation (5000W), operating temperature range (-55 to 175°C), and P600 axial package. The only difference is the packaging format: Tape & Reel versus Cut Tape.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on tape segments, typically used for manual or semi-automated assembly. Both formats contain the same component in the same package.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the SLD17U-017 and 5KP17A are automotive-grade components qualified to AEC-Q101 standard, meeting automotive reliability and quality requirements.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: reverse standoff voltage (17V), breakdown voltage (18.9V minimum), clamping voltage (27.6V maximum), peak pulse current (184.8A), power dissipation (5000W), unidirectional channel configuration (1 channel), package type (P600 axial), mounting method (through hole), and operating temperature range (-55 to 175°C).

Q: Are both parts RoHS compliant?

A: Yes. Both the SLD17U-017 and 5KP17A are RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).
