ZPY68-TAP Equivalent & Substitute Parts

Part Overview

The ZPY68-TAP is a 68 V, 1.3 W Zener diode manufactured by Vishay General Semiconductor - Diodes Division in DO-204AL (DO-41) axial through-hole package. This component is classified as an active product with automotive-grade qualification (AEC-Q101) and full RoHS3 compliance. Zener diodes of this specification are used in voltage regulation, overvoltage protection, and reference circuits where precise voltage clamping at 68 V is required. Substitute parts are identified when electrical parameters, package type, and compliance certifications align with application requirements, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ZPY68-TAP are identified based on strict alignment of the following critical parameters:

Electrical Equivalence:

• Zener voltage: 68 V nominal
• Tolerance: ±5%
• Power rating: 1.3 W maximum
• Package type: DO-204AL (DO-41) axial through-hole

Compliance & Grade:

• Automotive-grade classification
• AEC-Q101 qualification
• RoHS3 compliance
• Operating temperature: 175°C

Secondary Parameters (Allowed Variation):

• Impedance (Zzt): Variation permitted within acceptable circuit performance limits
• Reverse leakage current: Variation permitted; does not affect primary voltage regulation function
• Packaging format: Tape & Box (TB) vs. Cut Tape (CT) represents logistics variation only; electrical performance is identical

The 1N4760A-TAP qualifies as a direct substitute because it maintains identical nominal voltage, tolerance, power rating, package form, mounting type, grade, qualification, and compliance status. Differences in impedance and reverse leakage current are within acceptable engineering tolerances for this component category and do not compromise functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (ZPY68-TAP): Use the ZPY68-TAP when Tape & Box packaging is specified or preferred for inventory management. This part maintains active product status with full automotive qualification and AEC-Q101 certification. Impedance specification of 65 Ohms provides tighter dynamic response characteristics.

Substitute Selection (1N4760A-TAP): The 1N4760A-TAP is functionally equivalent and qualifies as a direct substitute. Both parts share identical electrical specifications for voltage regulation function, identical package form factor, and identical compliance certifications. The 1N4760A-TAP is available in Cut Tape packaging format and maintains significantly higher inventory availability (100,200 pcs vs. 840 pcs). Selection between these parts is determined by packaging format preference and supply chain availability rather than electrical performance differences.

Compliance Verification: Both parts satisfy automotive-grade requirements and AEC-Q101 qualification. Both are RoHS3 compliant with REACH unaffected status. Both are classified under ECCN EAR99 and HTSUS 8541.10.0050. No additional compliance verification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can 1N4760A-TAP replace ZPY68-TAP in existing designs without circuit modification?

A: Yes. Both parts are electrically equivalent for the 68 V voltage regulation function. Identical nominal voltage, tolerance, power rating, and operating temperature ensure functional compatibility. No circuit redesign or component value adjustment is required.

Q: What is the difference between Tape & Box (TB) and Cut Tape (CT) packaging?

A: Tape & Box and Cut Tape represent different packaging and delivery formats for the same component. TB packaging includes a box container for bulk storage; CT packaging is supplied on continuous tape for automated assembly equipment. Electrical performance and physical dimensions are identical. Selection depends on assembly process requirements and inventory management preferences.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts are rated for 175°C maximum operating temperature and carry identical automotive-grade classification with AEC-Q101 qualification. Thermal performance and reliability characteristics are equivalent.

Q: Why does 1N4760A-TAP show higher impedance (150 Ohms vs. 65 Ohms)?

A: Impedance variation within the specified range does not affect the primary voltage regulation function at the nominal 68 V operating point. Both values fall within acceptable engineering tolerances for this component category. Circuit performance for standard voltage clamping applications remains equivalent.

Q: Can these parts be used interchangeably in high-frequency or precision reference circuits?

A: For applications requiring impedance specifications tighter than 150 Ohms, the ZPY68-TAP with 65 Ohms impedance is the appropriate selection. For standard voltage regulation and overvoltage protection circuits, both parts are interchangeable.

Q: What is the reverse leakage current significance?

A: Reverse leakage current (500 nA vs. 5 µA) represents minor variation in off-state behavior. For voltage regulation and protection circuits, this difference does not affect functional performance. Both values are within acceptable limits for automotive applications.

Q: Are both parts available for immediate shipment?

A: Inventory status is subject to real-time availability. The 1N4760A-TAP shows significantly higher stock levels (100,200 pcs), which may provide supply chain advantages for high-volume requirements.
