P2300SA Equivalent & Substitute Parts

Part Overview

The P2300SA is a 190V off-state TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA (SMB) surface mount package. This component is designed for transient voltage suppression applications requiring 150A peak pulse current capability. The P2300SA is currently listed as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P2300SA is determined by electrical and mechanical compatibility across the following critical parameters:

• Voltage rating (off-state and breakover voltage)
• Peak pulse current capability (8/20µs and 10/1000µs)
• Hold current (Ih)
• Package type (DO-214AA, SMB)
• Mounting configuration (surface mount)

Two substitute parts are identified:

1. P2300SALRP - Direct equivalent from Littelfuse Inc., identical electrical specifications with tape & reel packaging
2. SMTPA200 - Cross-manufacturer substitute from STMicroelectronics with comparable electrical performance and identical package form factor

Parameter Comparison

Engineering Selection Recommendations

P2300SALRP is the direct equivalent substitute for P2300SA. Both components share identical electrical specifications and are from the same manufacturer. P2300SALRP is currently in active production status and is ROHS3 compliant, addressing the obsolescence of the original P2300SA. This part is the preferred choice for direct replacement in existing designs.

SMTPA200 is a cross-manufacturer substitute from STMicroelectronics. While electrical parameters are comparable, the off-state voltage is 200V (versus 190V) and the 10/1000µs peak pulse current is 50A (versus 45A). The capacitance is lower at 25pF. SMTPA200 is ROHS3 compliant and currently active. This part is suitable for applications where the slightly higher voltage rating and current capability are acceptable within design margins.

Frequently Asked Questions (FAQ)

Q: Can P2300SALRP be used as a direct replacement for P2300SA?

A: Yes. P2300SALRP is electrically and mechanically identical to P2300SA. The primary difference is packaging format (tape & reel versus bulk) and active production status. No design changes are required.

Q: What are the key differences between P2300SA and SMTPA200?

A: SMTPA200 has a 200V off-state voltage compared to P2300SA's 190V, a 10V higher breakover voltage (267V versus 260V), and 5A higher peak pulse current at 10/1000µs (50A versus 45A). Capacitance is lower at 25pF. All three parameters remain within typical application tolerances for TVS thyristor selection.

Q: Are both substitute parts available in the same package?

A: Yes. Both P2300SALRP and SMTPA200 are housed in DO-214AA (SMB) surface mount packages with identical mechanical form factors and PCB footprints.

Q: What compliance certifications apply to the substitute parts?

A: Both P2300SALRP and SMTPA200 are ROHS3 compliant. P2300SALRP carries REACH Affected status, while SMTPA200 is REACH Unaffected. Both are classified under ECCN EAR99.

Q: Which substitute should be selected for new designs?

A: For new designs, either P2300SALRP or SMTPA200 is acceptable based on voltage and current margin requirements. P2300SALRP maintains exact electrical parity with the original design. SMTPA200 offers slightly higher ratings and is suitable if design margins accommodate the voltage and current differences.
