Substitute Part Grouping Explanation

Substitute parts for the PTV8.2B-E3/84A are qualified based on strict electrical and mechanical parameter equivalence. All substitute candidates maintain the following critical specifications:

Zener voltage: 8.8 V nominal
Tolerance: ±6%
Maximum power dissipation: 600 mW
Maximum impedance: 4 Ohms
Reverse leakage current: 20 µA @ 5 V
Forward voltage: 1.5 V maximum @ 200 mA
Operating temperature: 150°C
Package configuration: DO-220AA (SMP) surface mount
Series designation: eSMP®
Compliance: ROHS3, REACH Unaffected

Substitution is permitted between parts sharing identical base product numbers (PTV8.2) and electrical ratings. Packaging variations (tape and reel versus alternative formats) do not affect functional equivalence when the component package and mounting type remain constant.

Engineering Selection Recommendations

The PTV8.2B-E3/84A is obsolete and should be replaced with an active equivalent for new designs and production continuity. Both substitute parts—PTV8.2B-M3/84A and PTV8.2B-M3/85A—are active products manufactured by the same supplier and maintain full electrical and mechanical compatibility.

PTV8.2B-M3/84A is the direct functional replacement, offering identical specifications with active product status and tape and reel packaging. This part is recommended as the primary substitute for direct replacement applications.

PTV8.2B-M3/85A is a parametric equivalent offering identical electrical performance and active product status. This part is suitable for applications where supply chain flexibility is required.

Both substitute parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. Moisture sensitivity level remains at MSL 1 (Unlimited) across all variants, indicating no special storage or handling requirements beyond standard component practices.

Frequently Asked Questions (FAQ)

Q: Can PTV8.2B-M3/84A be used as a direct replacement for PTV8.2B-E3/84A?

A: Yes. PTV8.2B-M3/84A is a direct substitute with identical electrical specifications, package configuration, and mounting type. The primary difference is product status: PTV8.2B-M3/84A is active while PTV8.2B-E3/84A is obsolete.

Q: What is the difference between PTV8.2B-M3/84A and PTV8.2B-M3/85A?

A: Both parts are parametric equivalents with identical electrical ratings and mechanical specifications. The difference lies in the suffix designation (84A versus 85A), which reflects different manufacturing batches or tape reel configurations. Both are active products suitable for substitution.

Q: Are there any packaging differences between the substitute parts?

A: PTV8.2B-E3/84A and both substitute parts use the same DO-220AA (SMP) surface mount package. PTV8.2B-M3/84A and PTV8.2B-M3/85A are supplied in tape and reel packaging, which is standard for high-volume surface mount assembly and does not affect component functionality.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory and environmental compliance is maintained across all variants.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The substitute parts maintain full electrical and mechanical compatibility with the original PTV8.2B-E3/84A. No circuit modifications or design changes are required for substitution.

Q: What is the significance of the eSMP® series designation?

A: eSMP® is the Vishay series designation for these surface mount Zener diodes. All three parts belong to this series, confirming consistent design and performance characteristics across the product line.
