Key Parameters

Substitute Part Grouping Explanation

Substitution of the PLVA650A/LF1R is determined by alignment of the following critical parameters:

Base Product Number Match: Both the main part and substitute parts share the base product number PLVA650, establishing functional equivalence within the PLVA6xxA series.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and identical ECCN and HTSUS classifications, ensuring regulatory interchangeability.

Moisture Sensitivity: MSL rating of 1 (Unlimited) is consistent across all parts, eliminating moisture-related handling restrictions as a substitution barrier.

Zener Voltage Rating: The 5 V nominal Zener voltage (Vz) is the primary electrical parameter defining functional equivalence for voltage regulation applications.

Power Dissipation: Maximum power rating of 250 mW establishes the thermal and current handling capability threshold for substitution eligibility.

Package Configuration: Surface mount TO-236AB package (SOT-23-3) provides mechanical and electrical compatibility for PCB assembly and circuit integration.

Tolerance and Electrical Characteristics: ±4% voltage tolerance, maximum impedance of 700 Ohms, reverse leakage current of 21 µA @ 4.5 V, and forward voltage of 900 mV @ 10 mA define the precision and performance envelope for substitution.

Engineering Selection Recommendations

Primary Selection Criteria:

The PLVA650A/LF1R remains the preferred component when available, given its active product status and established supply inventory of 1069 units. This part maintains full ROHS3 compliance and REACH Unaffected regulatory standing, suitable for applications requiring NXP USA Inc. sourcing specifications.

Substitute Part Selection:

The PLVA650A,215 manufactured by Nexperia USA Inc. is a qualified substitute when the primary part is unavailable. This substitute shares identical base product number (PLVA650), regulatory compliance profile (ROHS3, REACH Unaffected), and electrical classification (Zener diode, 5 V nominal). The substitute is supplied in Tape & Reel packaging with 3300 units in current inventory, providing enhanced supply availability.

Compliance Alignment:

Both parts maintain EAR99 ECCN classification and 8541.10.0050 HTSUS code, ensuring trade compliance equivalence. MSL rating of 1 (Unlimited) eliminates moisture-related handling constraints for either selection.

Automotive Grade Consideration:

The substitute part PLVA650A,215 carries AEC-Q101 automotive qualification, indicating suitability for automotive and high-reliability applications. This certification is not specified for the main part in the provided input data.

Frequently Asked Questions (FAQ)

Q: Can PLVA650A,215 be used as a direct replacement for PLVA650A/LF1R?

A: Yes. Both parts share the PLVA650 base product number, identical Zener voltage rating (5 V), matching power dissipation (250 mW), and equivalent regulatory compliance (ROHS3, REACH Unaffected). Surface mount package compatibility (SOT-23-3 / TO-236AB) supports direct PCB substitution.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by: Zener voltage (5 V nominal), maximum power rating (250 mW), voltage tolerance (±4%), impedance (700 Ohms maximum), reverse leakage current (21 µA @ 4.5 V), and forward voltage characteristics (900 mV @ 10 mA). These parameters establish functional equivalence for voltage regulation and protection circuits.

Q: Are there packaging differences between the main part and substitute?

A: Both parts use surface mount technology in TO-236AB package configuration (also designated TO-236-3, SC-59, SOT-23-3). The main part is specified as SOT23, and the substitute is supplied in Tape & Reel format. Physical footprint and electrical connectivity are equivalent for PCB assembly.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both PLVA650A/LF1R and PLVA650A,215 are ROHS3 compliant, REACH Unaffected, classified as EAR99 for export control, and assigned HTSUS code 8541.10.0050. MSL rating of 1 (Unlimited) applies to both parts, eliminating moisture sensitivity handling differences.

Q: What is the difference in manufacturer between the main part and substitute?

A: The main part is manufactured by NXP USA Inc., while the substitute is manufactured by Nexperia USA Inc. Both manufacturers produce components within the PLVA6xxA series. Nexperia is a subsidiary of NXP, ensuring design and quality alignment.

Q: Is the substitute part suitable for automotive applications?

A: The substitute part PLVA650A,215 carries AEC-Q101 automotive qualification, indicating compliance with automotive reliability and quality standards. The main part specification does not include automotive qualification data in the provided input.

Q: What inventory considerations should guide part selection?

A: The main part PLVA650A/LF1R has 1069 units in stock, while the substitute PLVA650A,215 has 3300 units available. For applications requiring immediate availability or high-volume procurement, the substitute offers enhanced supply continuity.
