BZD17C33P RUG Equivalent & Substitute Parts

Part Overview

The BZD17C33P RUG is a Zener diode manufactured by Taiwan Semiconductor Corporation, rated at 33 V nominal Zener voltage with 800 mW maximum power dissipation. This surface mount component operates across the temperature range of -55°C to 175°C and is packaged in the DO-219AB (Sub SMA) form factor. The device is ROHS3 compliant and carries an active product status.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including Zener voltage, power rating, impedance, leakage current, forward voltage characteristics, and package specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the BZD17C33P RUG is determined by strict equivalence across the following critical parameters:

Zener Voltage (Nominal): 33 V
Maximum Power Dissipation: 800 mW
Maximum Impedance: 15 Ohms
Reverse Leakage Current: 1 µA @ 24 V
Forward Voltage: 1.2 V @ 200 mA
Package Type: DO-219AB surface mount
Mounting Configuration: Surface mount

The identified substitute parts BZD27C33P-E3-08 and BZD27C33P-HE3-08, both manufactured by Vishay General Semiconductor - Diodes Division, meet all electrical and mechanical compatibility requirements. Both substitutes maintain identical Zener voltage, power rating, impedance, leakage current, and forward voltage specifications. Both are packaged in DO-219AB (SMF) form factor and support surface mount assembly. The operating temperature range of the substitutes extends to -65°C, providing an expanded lower temperature boundary compared to the original part.

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the BZD17C33P RUG across all specified parameters. All three components are ROHS3 compliant, REACH unaffected, and carry active product status.

BZD27C33P-E3-08 is suitable for general industrial applications requiring standard Zener diode performance at 33 V, 800 mW. This part is available in high volume (68,400 pieces in stock).

BZD27C33P-HE3-08 is qualified to AEC-Q101 automotive standards and carries automotive-grade designation. This part is appropriate for applications requiring automotive qualification compliance. Inventory availability is 9,400 pieces.

Selection between the two Vishay substitutes depends on application requirements. If automotive qualification is not mandated, either substitute provides equivalent performance. If automotive-grade components are specified, BZD27C33P-HE3-08 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can BZD27C33P-E3-08 or BZD27C33P-HE3-08 be used as direct replacements for BZD17C33P RUG?

A: Yes. Both Vishay parts are direct electrical and mechanical equivalents. All critical parameters including Zener voltage (33 V), power rating (800 mW), impedance (15 Ohms), leakage current (1 µA @ 24 V), and forward voltage (1.2 V @ 200 mA) are identical. Both are packaged in DO-219AB surface mount form factor and support identical PCB assembly processes.

Q: What is the difference between BZD27C33P-E3-08 and BZD27C33P-HE3-08?

A: The primary difference is automotive qualification. BZD27C33P-HE3-08 is AEC-Q101 qualified and designated as automotive-grade, making it suitable for automotive applications. BZD27C33P-E3-08 is a standard industrial-grade component. Electrical and mechanical specifications are identical between the two parts.

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

A: The original BZD17C33P RUG operates from -55°C to 175°C. Both substitute parts operate from -65°C to 175°C, providing an extended lower temperature boundary. This expanded range does not affect compatibility in applications using the original temperature specification.

Q: Do the substitute parts require different PCB layout or assembly procedures?

A: No. Both substitute parts use the identical DO-219AB surface mount package. PCB footprints, reflow profiles, and assembly procedures remain unchanged from the original BZD17C33P RUG.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. BZD17C33P RUG, BZD27C33P-E3-08, and BZD27C33P-HE3-08 are all ROHS3 compliant and REACH unaffected.

Q: Which substitute part should be selected for new designs?

A: For new designs without automotive requirements, either substitute provides equivalent performance. For automotive applications, BZD27C33P-HE3-08 is the appropriate selection due to AEC-Q101 qualification. Inventory availability should also be considered: BZD27C33P-E3-08 has higher stock levels (68,400 pieces) compared to BZD27C33P-HE3-08 (9,400 pieces).
