Equivalent & Substitute Parts for P2000SBRP

Part Overview

The P2000SBRP is a 180V off-state, 250A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA (SMB) surface mount package. This component is classified as obsolete, making identification of suitable alternatives necessary for ongoing design support and procurement continuity. The part provides transient voltage suppression through a thyristor mechanism with a 220V breakover voltage and 4V on-state voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for TVS thyristors is determined by matching the following critical parameters:

• Off-State Voltage: Must be 180V to maintain circuit protection threshold
• Breakover Voltage: Must be 220V for consistent triggering behavior
• On-State Voltage: Must be 4V to limit voltage clamping
• Peak Pulse Current (8/20µs): Must support 250A minimum for transient suppression capacity
• Package / Case: Must be DO-214AA (SMB) for PCB compatibility
• Mounting Type: Must be Surface Mount for assembly compatibility

Two substitute parts meet these criteria:

P2000SBLRP (Littelfuse Inc.) — Direct manufacturer equivalent with identical electrical specifications and same package, differentiated only by packaging format (Tape & Reel vs. bulk) and active product status.

SMTPA180 (STMicroelectronics) — Cross-manufacturer alternative with matching off-state voltage, breakover voltage, on-state voltage, and package, though with reduced peak pulse current rating (150A vs. 250A) and different hold current specification.

Parameter Comparison

Engineering Selection Recommendations

P2000SBLRP is the primary substitute for P2000SBRP. Both parts are manufactured by Littelfuse Inc. with identical electrical specifications and package configuration. P2000SBLRP holds active product status and ROHS3 compliance, addressing the obsolescence and regulatory limitations of the original part. The only functional difference is packaging format (Tape & Reel vs. bulk), which does not affect electrical performance or circuit compatibility.

SMTPA180 is a secondary cross-manufacturer alternative from STMicroelectronics. While it maintains the same off-state voltage, on-state voltage, and package type, it exhibits a higher breakover voltage (240V vs. 220V) and reduced peak pulse current capacity (150A vs. 250A). SMTPA180 is suitable only for applications where the lower current rating and higher breakover threshold do not compromise circuit protection requirements. This part also carries ROHS3 compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can P2000SBLRP be used as a direct replacement for P2000SBRP?

A: Yes. P2000SBLRP is electrically and mechanically identical to P2000SBRP. The difference is packaging format (Tape & Reel vs. bulk). Both parts have identical voltage ratings, current ratings, and DO-214AA package specifications.

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

A: SMTPA180 has a peak pulse current rating of 150A compared to P2000SBRP's 250A. Additionally, its breakover voltage is 240V versus 220V. These differences may affect transient suppression performance in high-current applications or circuits requiring precise voltage triggering at 220V.

Q: Are all substitute parts RoHS compliant?

A: P2000SBRP is RoHS non-compliant. Both P2000SBLRP and SMTPA180 are ROHS3 compliant, making them suitable for applications with RoHS regulatory requirements.

Q: Do the substitute parts fit the same PCB footprint?

A: Yes. All three parts use the DO-214AA (SMB) package and surface mount configuration, ensuring identical PCB footprint compatibility.

Q: Why does SMTPA180 have lower capacitance (25pF vs. 95pF)?

A: Capacitance differences reflect different internal device designs between manufacturers. The lower capacitance of SMTPA180 may affect high-frequency transient response characteristics compared to P2000SBRP.
