Substitute Part Grouping Explanation

Substitute parts for the PTV10B-E3/84A are identified based on strict 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 (SMP)
• Mounting Type: Surface Mount
• Series: eSMP®

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts PTV10B-M3/84A and PTV10B-M3/85A satisfy all electrical and mechanical requirements. The primary distinction is packaging format and product status, with both substitutes available in active production status.

Parameter Comparison

Engineering Selection Recommendations

Both PTV10B-M3/84A and PTV10B-M3/85A are direct functional equivalents to the obsolete PTV10B-E3/84A. Selection between these substitutes is based on the following factors:

Product Status: The PTV10B-E3/84A is classified as obsolete. Both substitute parts maintain active production status, ensuring long-term availability and supply chain continuity.

Compliance Certifications: All three parts maintain identical RoHS3 compliance and REACH unaffected status, confirming regulatory equivalence for applications requiring environmental compliance.

Packaging Considerations: The primary difference between the main part and substitutes is packaging format. The PTV10B-E3/84A is supplied in bulk format, while PTV10B-M3/84A and PTV10B-M3/85A are supplied in Tape & Reel (TR) format. This distinction affects procurement and assembly processes but does not impact electrical or mechanical performance.

Electrical Equivalence: All three parts are electrically identical across all specified parameters, including zener voltage, power rating, impedance, leakage current, and forward voltage characteristics.

For new designs or redesigns of existing applications using the PTV10B-E3/84A, either PTV10B-M3/84A or PTV10B-M3/85A provides direct substitution with improved product lifecycle support.

Frequently Asked Questions (FAQ)

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

A: Yes. Both substitute parts are electrically and mechanically identical to the PTV10B-E3/84A across all specified parameters. They are housed in the same DO-220AA package, operate at identical voltage and power ratings, and maintain the same tolerance and temperature specifications.

Q: What is the difference between PTV10B-M3/84A and PTV10B-M3/85A?

A: Both parts are electrically and mechanically identical. The difference in part number designation does not reflect differences in electrical specifications or package type. Both are supplied in Tape & Reel (TR) format and maintain active product status.

Q: Why is the PTV10B-E3/84A classified as obsolete?

A: The PTV10B-E3/84A has reached end-of-life status. Vishay General Semiconductor - Diodes Division has transitioned production to the active equivalents PTV10B-M3/84A and PTV10B-M3/85A. Existing inventory of the obsolete part is available, but new designs should utilize the active substitutes.

Q: Does the Tape & Reel (TR) packaging of the substitute parts affect circuit performance?

A: No. Tape & Reel packaging is a supply format that affects procurement and assembly processes but does not alter the electrical or mechanical characteristics of the component itself. The diode performance remains identical regardless of packaging format.

Q: Are all three parts RoHS3 compliant?

A: Yes. The PTV10B-E3/84A, PTV10B-M3/84A, and PTV10B-M3/85A are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), confirming regulatory equivalence for applications requiring environmental compliance.

Q: Can I use these parts in high-temperature applications?

A: All three parts are rated for operating temperatures up to 150°C. Applications requiring operation at or below this temperature are within specification for all parts.

Q: What is the impedance specification, and why is it important?

A: The impedance (Zzt) maximum of 6 Ohms is a dynamic impedance parameter that affects the zener diode's voltage regulation characteristics. All three parts maintain identical impedance specifications, ensuring equivalent voltage regulation performance in circuit applications.
