Substitute Part Grouping Explanation

Substitute parts for the PTV10B-E3/85A are qualified based on electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Electrical Parameters (Must Match):

Voltage - Zener (Nom): 10.6 V
Tolerance: ±6%
Power - Max: 600 mW
Impedance (Max): 6 Ohms
Current - Reverse Leakage @ Vr: 10 µA @ 7 V
Voltage - Forward (Vf) (Max) @ If: 1.5 V @ 200 mA
Operating Temperature: 150°C

Mechanical Parameters (Must Match):

Package / Case: DO-220AA
Mounting Type: Surface Mount
Series: eSMP®

Compliance Parameters (Must Match):

Engineering Selection Recommendations

The PTV10B-E3/85A is classified as obsolete. Direct substitution with PTV10B-M3/84A or PTV10B-M3/85A is supported based on complete electrical and mechanical parameter equivalence. Both substitute parts are active products manufactured by Vishay General Semiconductor - Diodes Division.

Selection Criteria:

PTV10B-M3/84A and PTV10B-M3/85A are functionally interchangeable with the PTV10B-E3/85A. The substitutes are supplied in Tape & Reel (TR) packaging format, which is standard for high-volume surface mount assembly operations. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing processes and environmental requirements.

The choice between PTV10B-M3/84A and PTV10B-M3/85A is determined by procurement requirements and supply chain considerations. Both parts are electrically and mechanically identical and are suitable for direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can PTV10B-M3/84A and PTV10B-M3/85A be used interchangeably with PTV10B-E3/85A?

A: Yes. All three parts are electrically and mechanically equivalent. They share identical zener voltage (10.6 V), power rating (600 mW), impedance (6 Ohms), and package configuration (DO-220AA surface mount). The substitute parts are active products, whereas the original part is obsolete.

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

A: The primary difference is product status and packaging format. The PTV10B-E3/85A is obsolete and supplied in standard packaging. The PTV10B-M3/84A and PTV10B-M3/85A are active products supplied in Tape & Reel (TR) format, which is optimized for automated surface mount assembly. All electrical specifications are identical.

Q: Are there any compliance or certification differences?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity). Compliance certifications are identical across all variants.

Q: Can these parts be used in new designs?

A: PTV10B-M3/84A and PTV10B-M3/85A are recommended for new designs due to their active product status and assured long-term availability. The PTV10B-E3/85A is obsolete and should not be specified for new applications.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel packaging is a supply and handling format used for automated assembly. It does not affect electrical performance, thermal characteristics, or reliability of the component itself.

Q: Are the forward voltage and reverse leakage specifications identical?

A: Yes. Voltage - Forward (Vf) is 1.5 V maximum at 200 mA, and Current - Reverse Leakage is 10 µA at 7 V for all three parts.
