Key Parameters

Substitute Part Grouping Explanation

Substitution for the P1701SARP is determined by the following critical parameters:

• Voltage - Clamping: 200V (primary electrical requirement)
• Package / Case: DO-214AA, SMB (mechanical and thermal compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Number of Circuits: 1 (functional equivalence)
• Applications: SLIC (application-specific requirement)

The substitute parts listed maintain these core parameters while offering improved product status and compliance characteristics. All substitutes are rated for 200V clamping voltage operation and utilize identical DO-214AA surface mount packaging, ensuring direct compatibility in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

P1701SALRP is the direct Littelfuse equivalent, maintaining the same manufacturer lineage and mixed technology platform. This part is active in production with ROHS3 compliance and identical electrical and mechanical specifications. Selection of P1701SALRP is appropriate for applications requiring continuity with the original Littelfuse product family.

SMP100LC-160 and SMP100MC-160 are STMicroelectronics alternatives that meet the core electrical requirements of 200V clamping voltage and DO-214AA packaging. Both parts are active in production with ROHS3 compliance. The primary difference between these two options is peak pulse current rating: SMP100LC-160 provides 400A (8/20µs) while SMP100MC-160 provides 300A (8/20µs). Selection between these options depends on the specific transient current handling requirements of the application.

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity classification and are suitable for surface mount assembly processes identical to the original P1701SARP.

Frequently Asked Questions (FAQ)

Q: Can P1701SALRP be used as a direct replacement for P1701SARP?

A: Yes. P1701SALRP maintains identical electrical parameters (200V clamping voltage), mechanical specifications (DO-214AA package), and application focus (SLIC). The primary advantage is active product status and ROHS3 compliance.

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

A: Both parts share identical clamping voltage (200V), off-state voltage (160V), and package specifications (DO-214AA). The distinction is peak pulse current capacity: SMP100LC-160 handles 400A (8/20µs) while SMP100MC-160 handles 300A (8/20µs). Selection depends on transient current requirements in the specific application.

Q: Are the STMicroelectronics parts (SMP100 series) compatible with the original P1701SARP footprint?

A: Yes. Both SMP100LC-160 and SMP100MC-160 use DO-214AA surface mount packaging, which is mechanically and thermally identical to the P1701SARP package. Direct PCB substitution is possible without layout modifications.

Q: What compliance advantages do the substitute parts offer?

A: P1701SALRP, SMP100LC-160, and SMP100MC-160 are all ROHS3 compliant, whereas the original P1701SARP is RoHS non-compliant. All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: Which substitute part should be selected for new designs?

A: For new designs, selection should be based on specific transient current handling requirements. If 300A peak pulse current is sufficient, SMP100MC-160 is appropriate. If 400A peak pulse current is required, SMP100LC-160 is the selection. Both are active products with full compliance certifications.
