Engineering Selection Recommendations

All three substitute parts—BZD27C68P-E3-08, BZD27C68P-E3-18, and BZD27C68P-M3-08—are direct functional equivalents to the BZD17C68P RVG. Selection among these alternatives is based on packaging and inventory availability:

BZD27C68P-E3-08: Supplied in Cut Tape (CT) & Digi-Reel® packaging with 6,200 units in stock. Suitable for applications requiring smaller quantity orders or mixed component sourcing.

BZD27C68P-E3-18: Supplied in Tape & Reel (TR) packaging with 50,909 units in stock. Recommended for high-volume production runs and automated assembly processes requiring standard reel quantities.

BZD27C68P-M3-08: Supplied in Tape & Reel (TR) packaging with 17,300 units in stock. Provides an intermediate inventory option for medium-volume applications.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical electrical performance specifications. The extended lower operating temperature range (-65°C versus -55°C) of the substitute parts provides additional thermal margin for applications operating in cold environments.

Frequently Asked Questions (FAQ)

Q: Can BZD27C68P variants be used as direct replacements for BZD17C68P RVG?

A: Yes. The BZD27C68P-E3-08, BZD27C68P-E3-18, and BZD27C68P-M3-08 are direct functional equivalents. All parts share identical Zener voltage (68 V), maximum power dissipation (800 mW), impedance (80 Ohms), reverse leakage current (1 µA @ 51 V), forward voltage (1.2 V @ 200 mA), and package type (DO-219AB). Electrical performance and mechanical compatibility are fully equivalent.

Q: What is the difference between the three substitute part numbers?

A: The three substitute parts differ only in packaging format and inventory availability. BZD27C68P-E3-08 is supplied in Cut Tape & Digi-Reel format. BZD27C68P-E3-18 and BZD27C68P-M3-08 are both supplied in Tape & Reel format. All three maintain identical electrical specifications and DO-219AB package compatibility.

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

A: The substitute parts operate across -65°C to 175°C, while the main part operates across -55°C to 175°C. The substitute parts provide an extended lower temperature range, which is compatible with all applications designed for the original part's temperature range.

Q: Do all parts meet the same compliance standards?

A: Yes. The main part and all three substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All parts are classified as active products.

Q: Which substitute part should be selected for high-volume production?

A: BZD27C68P-E3-18 is recommended for high-volume production due to its Tape & Reel packaging format and largest available inventory (50,909 units), which aligns with standard automated assembly processes.

Q: Are there any impedance or leakage current differences?

A: No. All parts maintain identical maximum impedance of 80 Ohms and reverse leakage current of 1 µA @ 51 V. These parameters are critical for voltage regulation performance and are fully matched across all equivalent parts.
