Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P1502SBLRP is determined by the following critical parameters:

• Voltage - Off State: Must equal 140V
• Package / Case: Must be DO-214AA, SMB (Surface Mount)
• Mounting Type: Must be Surface Mount
• Product Status: Must be Active
• RoHS Compliance: Must maintain ROHS3 Compliant status

The SMP100LC-140 manufactured by STMicroelectronics meets these core substitution criteria. Both components share identical off-state voltage (140V), package format (DO-214AA, SMB), and compliance certifications. Differences in peak pulse current ratings and capacitance values represent performance variations within acceptable substitution parameters for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the P1502SBLRP and SMP100LC-140 maintain Active product status and full compliance with ROHS3 and REACH regulations. Selection between these components should be based on application-specific current handling requirements and circuit design parameters. The SMP100LC-140 provides higher peak pulse current capacity (400A vs. 250A at 8/20µs), while the P1502SBLRP features lower capacitance (30pF vs. 65pF). Both components are suitable for 140V off-state transient voltage suppression applications in Surface Mount configurations.

Frequently Asked Questions (FAQ)

Q: Can the SMP100LC-140 directly replace the P1502SBLRP in my circuit?

A: Both components share the same off-state voltage (140V), package format (DO-214AA, SMB), and mounting type (Surface Mount). Compatibility depends on your circuit's current handling requirements and capacitance tolerance specifications.

Q: What is the significance of the different number of elements (2 vs. 1)?

A: The P1502SBLRP contains 2 elements (TwinChip™ configuration), while the SMP100LC-140 contains 1 element. This structural difference contributes to variations in electrical characteristics such as capacitance and current ratings.

Q: Are there packaging differences between these parts?

A: The P1502SBLRP is supplied in Tape & Reel (TR) format, while the SMP100LC-140 is available in Cut Tape (CT) and Digi-Reel® formats. Both use the same DO-214AA, SMB package case for Surface Mount assembly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the P1502SBLRP and SMP100LC-140 are ROHS3 Compliant, REACH Unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited).

Q: What is the difference in breakover voltage between these parts?

A: The P1502SBLRP has a breakover voltage of 180V, while the SMP100LC-140 has a breakover voltage of 175V. Both maintain the same 140V off-state voltage specification.
