Substitute Part Grouping Explanation

Substitute parts for the BZD27C8V2P RVG are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

Zener voltage: 8.2 V nominal
Package type: DO-219AB (Sub SMA / SMF)
Mounting type: Surface Mount
Impedance (Max): 2 Ohms
Current - Reverse Leakage @ Vr: 10 µA @ 3 V
Voltage - Forward (Vf) (Max) @ If: 1.2 V @ 200 mA
RoHS3 Compliance
Moisture Sensitivity Level: 1 (Unlimited)

Power Rating Consideration: Substitute parts rated at 800 mW (0.8 W) are acceptable alternatives to the 1 W main part, as they meet the minimum power dissipation requirements for equivalent circuit applications while maintaining all other electrical specifications.

Operating Temperature Range: Substitute parts with extended lower temperature limits (-65°C vs. -55°C) provide enhanced performance margins and are fully compatible with the original specification range.

Frequently Asked Questions (FAQ)

Q: Can BZD27C8V2P RVG be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts maintain identical Zener voltage (8.2 V), impedance (2 Ohms), reverse leakage current (10 µA @ 3 V), forward voltage (1.2 V @ 200 mA), and package type (DO-219AB). The 800 mW power rating of substitute parts is acceptable for applications designed for the 1 W original part.

Q: What is the difference between the various Vishay part number suffixes (-E3, -HE3, -M, -M3)?

A: The suffixes indicate different manufacturing series and packaging configurations within the Vishay BZD27C8V2 product line. All variants maintain identical electrical specifications. The -HE3 designation indicates automotive-grade qualification (AEC-Q101). The -M and -M3 designations represent different manufacturing series. Selection should be based on application requirements and packaging format availability.

Q: Are the 800 mW substitute parts suitable for circuits designed for 1 W Zener diodes?

A: The 800 mW substitute parts are suitable when the circuit design does not require the full 1 W power dissipation capability. Circuit analysis must confirm that maximum power dissipation does not exceed 800 mW under all operating conditions, including worst-case scenarios.

Q: What is the significance of the operating temperature range difference (-55°C to 175°C vs. -65°C to 175°C)?

A: The substitute parts with -65°C lower limit provide extended performance margin at low temperatures. This extended range is fully backward compatible with the original -55°C specification and does not introduce any compatibility issues.

Q: Which substitute part should be selected for automotive applications?

A: BZD27C8V2P-HE3-08 and BZD27C8V2P-HE3-18 are qualified to AEC-Q101 automotive standards and must be used for applications requiring automotive-grade components. These parts are designated with the automotive grade classification in their product specifications.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Most substitute parts are available in Tape & Reel (TR) packaging. BZD27C8V2P-M-08 and BZD27C8V2P-M-18 do not specify packaging format in the provided data. Packaging format should be confirmed with the supplier for automated assembly requirements.

Q: Do all parts maintain the same moisture sensitivity level?

A: Yes. All parts, including the original BZD27C8V2P RVG and all substitutes, are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
