Substitute Part Grouping Explanation

Substitution eligibility for the BZD17C39P RVG is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

Nominal Zener voltage of 39 V
Maximum power dissipation of 800 mW
Maximum impedance of 40 Ohms
Reverse leakage current of 1 µA @ 30 V
Forward voltage of 1.2 V @ 200 mA

Mechanical & Environmental Requirements:

DO-219AB package type
Surface mount mounting configuration
Operating temperature range support (minimum -55°C to 175°C)
RoHS3 compliance
MSL 1 (Unlimited) moisture sensitivity rating

Both identified substitute parts (BZD27C39P-E3-08 and BZD27C39P-HE3-08) satisfy all electrical and mechanical equivalence criteria. The BZD27C39P series from Vishay General Semiconductor maintains identical electrical specifications and package compatibility while offering extended lower temperature operation (-65°C minimum versus -55°C).

Frequently Asked Questions (FAQ)

Q: Can BZD27C39P-E3-08 or BZD27C39P-HE3-08 be used as direct replacements for BZD17C39P RVG?

A: Yes. Both substitute parts maintain identical nominal Zener voltage (39 V), maximum power rating (800 mW), impedance specification (40 Ohms), and package type (DO-219AB). All electrical parameters including reverse leakage current and forward voltage are equivalent. Surface mount configuration and RoHS3 compliance are maintained across all three parts.

Q: What is the difference between BZD27C39P-E3-08 and BZD27C39P-HE3-08?

A: Both parts are electrically and mechanically identical. The primary distinction is that BZD27C39P-HE3-08 carries AEC-Q101 automotive qualification and Automotive grade designation, while BZD27C39P-E3-08 is a standard industrial-grade component. Selection depends on application requirements for automotive compliance.

Q: Are there temperature range differences between the main part and substitutes?

A: The BZD17C39P RVG operates from -55°C to 175°C. Both substitute parts (BZD27C39P-E3-08 and BZD27C39P-HE3-08) extend the lower temperature limit to -65°C while maintaining the 175°C upper limit. This provides enhanced cold-temperature performance without affecting upper temperature operation.

Q: Do the substitute parts use the same package as the main part?

A: Yes. All three parts use the DO-219AB package type configured for surface mount assembly. The mechanical footprint and land pattern are identical, enabling direct PCB layout compatibility.

Q: Are RoHS and REACH compliance maintained with substitute parts?

A: Yes. Both BZD27C39P-E3-08 and BZD27C39P-HE3-08 maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory compliance profile of BZD17C39P RVG.

Q: What is the moisture sensitivity level for substitute parts?

A: Both substitute parts carry MSL 1 (Unlimited) rating, identical to the main part. This indicates unlimited shelf life under standard storage conditions without baking requirements.

Q: Are substitute parts currently in stock?

A: Yes. BZD27C39P-E3-08 has 9300 units available, and BZD27C39P-HE3-08 has 3300 units available as new original inventory.
