P2000SC Equivalent & Substitute Parts

Part Overview

The P2000SC is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for overvoltage protection in surface mount applications. This component features a 180V off-state voltage rating with 400A peak pulse current capability in a DO-214AA (SMB) package. The P2000SC is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitute parts for the P2000SC are identified based on matching electrical and mechanical parameters within acceptable tolerances for TVS thyristor applications. The primary substitution criteria are:

• Voltage - Off State: 180V (exact match required)
• Voltage - Breakover: 220V to 240V range (acceptable variation)
• Current - Peak Pulse (8/20µs): 150A minimum (derating acceptable for active alternatives)
• Package / Case: DO-214AA, SMB (mechanical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)

Two substitute categories are identified: direct manufacturer equivalents from Littelfuse Inc. and manufacturer-recommended alternatives from qualified suppliers.

Parameter Comparison

Engineering Selection Recommendations

P2000SCLRP (Littelfuse Inc.) is the primary direct equivalent for P2000SC replacement. This part maintains identical electrical specifications including 180V off-state voltage, 220V breakover voltage, 400A peak pulse current (8/20µs), and 120mA hold current. The P2000SCLRP is active in production status and ROHS3 compliant, addressing regulatory requirements that the obsolete P2000SC does not meet. Packaging differs only in format (Tape & Reel versus bulk), with no impact on component performance or assembly compatibility.

SMTPA180 (STMicroelectronics) is a manufacturer-recommended alternative for applications where current derating is acceptable. This part matches the 180V off-state voltage and DO-214AA package but provides 150A peak pulse current (8/20µs) and 50A peak pulse current (10/1000µs), representing a 62.5% reduction in 8/20µs current rating and 50% reduction in 10/1000µs current rating compared to P2000SC. The SMTPA180 is active in production and ROHS3 compliant. Selection of SMTPA180 requires circuit analysis to confirm that reduced current ratings do not compromise overvoltage protection performance.

Both substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the environmental handling requirements of the original P2000SC.

Frequently Asked Questions (FAQ)

Q: Can P2000SCLRP be used as a direct replacement for P2000SC?

A: Yes. P2000SCLRP is electrically and mechanically identical to P2000SC, with matching voltage ratings (180V off-state, 220V breakover), current ratings (400A peak pulse 8/20µs, 100A peak pulse 10/1000µs), and hold current (120mA). The only difference is packaging format (Tape & Reel). Both components use the DO-214AA (SMB) package and are surface mount compatible.

Q: What are the limitations of SMTPA180 as a substitute?

A: SMTPA180 has reduced current ratings: 150A peak pulse (8/20µs) versus 400A for P2000SC, and 50A peak pulse (10/1000µs) versus 100A for P2000SC. The off-state voltage (180V) and package (DO-214AA, SMB) remain compatible. Applications requiring the full 400A current handling capability cannot use SMTPA180 without circuit redesign.

Q: Are there compliance differences between P2000SC and its substitutes?

A: Yes. P2000SC is RoHS non-compliant. Both P2000SCLRP and SMTPA180 are ROHS3 compliant. If your application or supply chain requires RoHS compliance, P2000SC cannot be used; P2000SCLRP or SMTPA180 must be selected.

Q: Do all three parts have the same moisture sensitivity requirements?

A: Yes. P2000SC, P2000SCLRP, and SMTPA180 all carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions for storage, handling, or assembly.

Q: What is the breakover voltage difference between P2000SC and SMTPA180?

A: P2000SC has a 220V breakover voltage, while SMTPA180 has a 240V breakover voltage. This 20V difference may affect circuit protection thresholds and requires verification during design substitution.
