P1701SCRP Equivalent & Substitute Parts

Part Overview

The P1701SCRP is a Transient Voltage Suppressor (TVS) device manufactured by Littelfuse Inc., designed for SLIC applications with a clamping voltage of 200V in a DO-214AA surface mount package. This part is classified as obsolete, making equivalent substitute components necessary for new designs and ongoing production requirements. The TwinSLIC™ series device provides mixed technology circuit protection in a compact SMB form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P1701SCRP are qualified based on the following critical parameters that determine functional equivalence:

Matching Criteria:

• Package / Case: DO-214AA, SMB (identical physical form factor)
• Mounting Type: Surface Mount (same PCB assembly compatibility)
• Voltage - Breakover: 200V (equivalent transient suppression threshold)
• Number of Elements: 1 (single circuit configuration)
• Moisture Sensitivity Level: 1 (Unlimited) (same handling requirements)

The substitute parts SMP100LC-160 and SMP100MC-160 from STMicroelectronics meet these core electrical and mechanical requirements. Both devices operate with a 200V breakover voltage and 160V off-state voltage, providing equivalent protection characteristics in the same DO-214AA package. The primary differentiation between substitutes is the peak pulse current rating, which varies based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both SMP100LC-160 and SMP100MC-160 are active, production-qualified alternatives to the obsolete P1701SCRP. Selection between these substitutes depends on application current requirements:

SMP100LC-160 provides 400 A peak pulse current (8/20µs) and is suitable for applications requiring maximum transient suppression capacity.

SMP100MC-160 provides 300 A peak pulse current (8/20µs) and is suitable for applications with moderate transient suppression requirements.

Both substitute parts are ROHS3 compliant, addressing regulatory requirements that the original P1701SCRP does not meet. The identical DO-214AA package and surface mount configuration ensure direct PCB layout compatibility without redesign. Identical breakover voltage (200V) and off-state voltage (160V) characteristics maintain equivalent circuit protection performance.

Frequently Asked Questions (FAQ)

Q: Can SMP100LC-160 and SMP100MC-160 be used interchangeably with P1701SCRP?

A: Both parts are functionally equivalent substitutes for the P1701SCRP in the same DO-214AA package with matching 200V breakover voltage. Selection between them depends on the application's peak pulse current requirement. SMP100LC-160 handles 400 A, while SMP100MC-160 handles 300 A.

Q: What is the primary difference between SMP100LC-160 and SMP100MC-160?

A: The primary difference is peak pulse current rating. SMP100LC-160 is rated for 400 A (8/20µs), while SMP100MC-160 is rated for 300 A (8/20µs). Both share identical breakover voltage, off-state voltage, and package specifications.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both SMP100LC-160 and SMP100MC-160 are ROHS3 compliant, whereas the original P1701SCRP is RoHS non-compliant.

Q: Will the substitute parts fit the existing PCB layout?

A: Yes. Both substitute parts use the identical DO-214AA, SMB package and surface mount configuration as the P1701SCRP, requiring no PCB layout modifications.

Q: What is the moisture sensitivity level for the substitute parts?

A: Both SMP100LC-160 and SMP100MC-160 have Moisture Sensitivity Level (MSL) 1 (Unlimited), matching the original P1701SCRP specification.
