Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2500SBLRP is determined by the following critical electrical and mechanical parameters:

• Voltage - Off State: Must be 230V to maintain circuit protection threshold compatibility
• Package / Case: Must be DO-214AA (SMB) to ensure mechanical and thermal compatibility with existing PCB layouts
• Mounting Type: Must be Surface Mount to align with assembly process requirements
• Number of Elements: Must be 1 to match functional architecture

The substitute part SMP100LC-230 meets all mandatory substitution criteria. While the substitute exhibits higher peak pulse current ratings (400A vs. 250A at 8/20µs), lower capacitance (60pF vs. 95pF), and higher hold current (150mA vs. 120mA), these variations remain within acceptable operational parameters for TVS thyristor applications and do not preclude functional equivalence in the specified voltage class.

Parameter Comparison

Engineering Selection Recommendations

Both the P2500SBLRP and SMP100LC-230 are active production components with full RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications. Both components carry MSL 1 (Unlimited) moisture sensitivity classification, eliminating moisture-related handling constraints.

The P2500SBLRP is the primary component specification. The SMP100LC-230 serves as a qualified substitute when P2500SBLRP availability is constrained. Selection between these parts should be based on supply chain availability, lead time requirements, and procurement cost considerations. Both parts are suitable for direct substitution in 230V TVS thyristor protection circuits without design modification.

Frequently Asked Questions (FAQ)

Q: Can SMP100LC-230 be used as a direct replacement for P2500SBLRP?

A: Yes. Both components share identical off-state voltage (230V), package type (DO-214AA, SMB), mounting method (Surface Mount), and element count (1). The substitute meets all mandatory mechanical and electrical compatibility criteria for TVS thyristor applications in this voltage class.

Q: What are the key differences between these parts?

A: The SMP100LC-230 provides higher peak pulse current capacity (400A vs. 250A at 8/20µs) and higher hold current (150mA vs. 120mA), while exhibiting lower capacitance (60pF vs. 95pF). The breakover voltage is slightly lower (285V vs. 290V). These differences do not affect functional substitution within the 230V protection specification.

Q: Are there packaging differences between P2500SBLRP and SMP100LC-230?

A: Both components use the DO-214AA (SMB) package for surface mount assembly. The P2500SBLRP is supplied in Tape & Reel (TR) format, while SMP100LC-230 is available in Cut Tape (CT) and Digi-Reel® formats. Package case dimensions and PCB footprints are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both P2500SBLRP and SMP100LC-230 are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification. Both are classified under ECCN EAR99 and HTSUS 8541.30.0080.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection should be based on component availability, supplier preference, and procurement lead time. Both parts are in active production status and suitable for long-term supply chain planning.
