Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P1701SCLRP are qualified based on the following critical parameters that determine functional equivalence:

• Voltage - Off State: 160V (exact match required)
• Voltage - Breakover: 200V (exact match required)
• Package / Case: DO-214AA, SMB (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Current - Peak Pulse (8/20µs): 400A or higher acceptable
• Current - Peak Pulse (10/1000µs): 100A (exact match required)
• Number of Elements: 1 (exact match required)
• Product Status: Active (required for ongoing supply)
• RoHS Status: ROHS3 Compliant (required for compliance)

The identified substitutes are manufactured by STMicroelectronics under the SMP and TRISIL™ series. Both substitute parts maintain the critical voltage and package specifications while offering variations in peak pulse current handling and hold current characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both STMicroelectronics substitutes maintain active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity.

SMP100LC-160 provides direct current equivalence at 400A peak pulse (8/20µs), matching the P1701SCLRP specification. This part is available in Cut Tape (CT) and Digi-Reel® packaging with 5074 units in stock.

SMP100MC-160 operates at 300A peak pulse (8/20µs), representing a reduced current rating. This part is available in Cut Tape (CT) packaging with 3900 units in stock. Selection of this part requires confirmation that the application does not demand the full 400A peak pulse capability of the original specification.

Both substitutes exhibit higher hold current (150mA versus 120mA) and lower capacitance values compared to the P1701SCLRP, which may influence circuit behavior in specific applications.

Frequently Asked Questions (FAQ)

Q: Can SMP100LC-160 be used as a direct replacement for P1701SCLRP?

A: Yes. SMP100LC-160 matches all critical parameters: 160V off-state voltage, 200V breakover voltage, 400A peak pulse current (8/20µs), 100A peak pulse current (10/1000µs), DO-214AA SMB package, and active product status with ROHS3 compliance.

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

A: The primary difference is peak pulse current rating. SMP100LC-160 is rated for 400A (8/20µs), while SMP100MC-160 is rated for 300A (8/20µs). Both maintain identical voltage specifications and package form factor. SMP100MC-160 also features lower capacitance (50pF versus 65pF).

Q: Can SMP100MC-160 replace P1701SCLRP in all applications?

A: SMP100MC-160 is suitable only for applications where peak pulse current does not exceed 300A (8/20µs). Applications requiring the full 400A capability must use SMP100LC-160 or the original P1701SCLRP.

Q: Are there packaging differences between these parts?

A: P1701SCLRP is supplied in Tape & Reel (TR) packaging. SMP100LC-160 is available in Cut Tape (CT) and Digi-Reel® packaging. SMP100MC-160 is available in Cut Tape (CT) packaging. All three parts use identical DO-214AA SMB surface mount package form factor.

Q: Do these substitutes have the same hold current specification?

A: No. P1701SCLRP specifies 120mA hold current, while both SMP100LC-160 and SMP100MC-160 specify 150mA hold current. This difference may affect circuit behavior in specific applications and should be evaluated during design review.

Q: Are all three parts RoHS compliant?

A: Yes. P1701SCLRP, SMP100LC-160, and SMP100MC-160 are all ROHS3 compliant with MSL rating of 1 (Unlimited).
