P2600SCLRP Equivalent & Substitute Parts

Part Overview

The P2600SCLRP is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., classified within the SIDACtor® series. This component operates at 220V off-state voltage with a peak pulse current rating of 400A (8/20µs), housed in a DO-214AA SMB package for surface mount applications. The part is currently Active in product status and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified when alternative components meet the same electrical and mechanical requirements for specific application contexts.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2600SCLRP is determined by alignment of the following critical parameters: off-state voltage rating, peak pulse current capacity (8/20µs), package type (DO-214AA SMB), mounting configuration (surface mount), and compliance certifications (RoHS3, REACH Unaffected). The identified substitute parts are grouped based on voltage class and current handling capability.

SMP100LC-230 qualifies as a substitute when 230V off-state voltage is acceptable within the application tolerance, maintaining the 400A peak pulse current (8/20µs) and identical package specifications.

SMTPA220 qualifies as a substitute when peak pulse current requirements can be reduced to 150A (8/20µs) while maintaining the 220V off-state voltage and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three components maintain Active product status and full RoHS3 compliance with REACH Unaffected designation, ensuring regulatory alignment for current design implementations.

SMP100LC-230 provides direct functional equivalence when the application permits a 10V increase in off-state voltage (from 220V to 230V) and a 15V reduction in breakover voltage (from 300V to 285V). This substitute maintains identical peak pulse current capacity (400A at 8/20µs) and current hold specifications.

SMTPA220 maintains the exact 220V off-state voltage and 293V breakover voltage of the main part but reduces peak pulse current handling to 150A (8/20µs). This substitute is applicable only when the application's transient current requirements do not exceed 150A.

Component selection must be based on the specific voltage and current requirements of the target application circuit.

Frequently Asked Questions (FAQ)

Q: Can SMP100LC-230 be used as a direct replacement for P2600SCLRP?

A: SMP100LC-230 is functionally equivalent when the application tolerates a 230V off-state voltage instead of 220V. Both components share identical 400A peak pulse current (8/20µs), 150mA hold current, and DO-214AA SMB package specifications. Voltage tolerance of the protected circuit determines compatibility.

Q: What is the primary difference between SMP100LC-230 and SMTPA220?

A: SMP100LC-230 maintains 400A peak pulse current capacity, while SMTPA220 is rated for 150A peak pulse current. Both operate at 220V or 230V off-state voltage. Selection depends on the maximum transient current the application will experience.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three components use the DO-214AA SMB package with identical surface mount configuration, ensuring footprint compatibility across P2600SCLRP, SMP100LC-230, and SMTPA220.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. P2600SCLRP, SMP100LC-230, and SMTPA220 are all RoHS3 compliant with REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute should be selected for a 220V application requiring 400A peak pulse current?

A: SMP100LC-230 is the appropriate selection, as it maintains the 400A peak pulse current specification while operating at 230V off-state voltage. If exact 220V operation is required, P2600SCLRP remains the primary component.
