P2500SARP Equivalent & Substitute Parts

Part Overview

The P2500SARP is a 230V off-state, 150A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA SMB package. This component is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement planning. The part provides transient voltage suppression for applications requiring 230V nominal protection levels with moderate current handling capacity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P2500SARP is determined by the following critical parameters: off-state voltage (230V), package type (DO-214AA SMB), mounting configuration (surface mount), and single-element design. Substitute parts must maintain electrical compatibility within the specified voltage class and current handling requirements.

Two substitute categories are identified:

Direct Functional Equivalent: P2500SALRP maintains identical electrical specifications and package configuration, differing only in packaging format (tape & reel versus cut tape) and product status (active versus obsolete).

Higher Current Capability Alternative: SMP100LC-230 provides the same 230V off-state voltage and DO-214AA SMB package but with enhanced current handling (400A peak pulse versus 150A), making it suitable for applications requiring greater transient current capacity within the same voltage protection class.

Parameter Comparison

Engineering Selection Recommendations

P2500SALRP is the primary substitute for P2500SARP. It provides identical electrical performance and package configuration while offering active product status and ROHS3 compliance. This part is recommended for direct replacement in existing designs where the original P2500SARP specifications are required and current availability is necessary.

SMP100LC-230 is suitable for applications where increased transient current handling is beneficial or required. The 400A peak pulse capability (versus 150A) and higher hold current (150mA versus 120mA) provide enhanced protection margins. The slightly lower breakover voltage (285V versus 290V) and increased capacitance (60pF versus 35pF) must be evaluated against specific circuit requirements. This part is recommended when design margins permit the parameter variations and higher current capacity is advantageous.

Both substitute parts maintain the 230V off-state voltage, DO-214AA SMB package, and surface mount configuration necessary for mechanical and electrical compatibility. Both are ROHS3 compliant and REACH unaffected, supporting modern procurement and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can P2500SALRP be used as a direct replacement for P2500SARP?

A: Yes. P2500SALRP maintains identical electrical specifications (230V off-state, 150A peak pulse, 4V on-state, 120mA hold current) and package configuration (DO-214AA SMB). The only differences are packaging format (tape & reel versus cut tape) and product status (active versus obsolete). No circuit modifications are required.

Q: What are the key differences between P2500SARP and SMP100LC-230?

A: Both parts share the same 230V off-state voltage and DO-214AA SMB package. SMP100LC-230 provides higher current capacity (400A peak pulse versus 150A) and higher hold current (150mA versus 120mA). The breakover voltage is slightly lower (285V versus 290V), and capacitance is higher (60pF versus 35pF). These differences must be evaluated against circuit-specific requirements.

Q: Are packaging differences between P2500SALRP and P2500SARP significant?

A: Packaging format differences (tape & reel versus cut tape) affect procurement and handling but do not impact electrical performance or circuit compatibility. Both use identical DO-214AA SMB packages suitable for surface mount assembly.

Q: Which substitute should be selected for new designs?

A: P2500SALRP is recommended for designs requiring the original P2500SARP specifications. SMP100LC-230 is recommended when higher transient current capacity is beneficial or when design margins permit the parameter variations. Both parts are active products with modern compliance certifications.

Q: Are there compliance or environmental differences between the substitutes?

A: P2500SARP is RoHS non-compliant. Both P2500SALRP and SMP100LC-230 are ROHS3 compliant and REACH unaffected. For applications requiring modern environmental compliance, either substitute is suitable.
