1N4697-TP Equivalent & Substitute Parts

Part Overview

The 1N4697-TP is a Zener diode rated at 10 V nominal voltage with 500 mW power dissipation in a DO-35 axial through-hole package. Manufactured by Micro Commercial Co, this component is classified as obsolete product status. Due to its obsolete designation, locating equivalent substitute parts with identical electrical and mechanical specifications is necessary for ongoing design support and production continuity. Substitute parts must maintain the same voltage rating, power rating, tolerance, and package configuration to ensure direct functional replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N4697-TP is determined by strict equivalence across the following critical parameters:

• Voltage - Zener (Nom): 10 V (exact match required)
• Power - Max: 500 mW (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage - Forward (Vf) (Max) @ If: 1.5 V @ 100 mA (exact match required)
• Package / Case: DO-35, Axial (exact match required)
• Mounting Type: Through Hole (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)

The BZX79C10 manufactured by Taiwan Semiconductor Corporation meets all specified electrical and mechanical parameters. This part is classified as active product status, ensuring ongoing availability and supply chain support. Both parts share identical zener voltage, power rating, tolerance, forward voltage characteristics, and package configuration.

Frequently Asked Questions (FAQ)

Q: Can the BZX79C10 be used as a direct replacement for the 1N4697-TP in existing designs?

A: Yes. The BZX79C10 meets all specified electrical parameters (10 V zener voltage, 500 mW power rating, ±5% tolerance, 1.5 V forward voltage at 100 mA) and shares identical DO-35 axial through-hole packaging. Direct substitution is supported without circuit modification.

Q: What is the primary reason for substituting the 1N4697-TP?

A: The 1N4697-TP is classified as obsolete product status. The BZX79C10 is an active product, ensuring ongoing manufacturer support, availability, and supply chain reliability.

Q: Are there any differences in operating temperature ranges between these parts?

A: The 1N4697-TP specifies a maximum operating temperature of 200°C (TJ). The BZX79C10 specifies an operating temperature range of -65°C to 175°C (TJ). Both parts operate within acceptable thermal ranges for standard through-hole zener diode applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1N4697-TP and BZX79C10 are ROHS3 compliant. Both parts share the same ECCN (EAR99) and HTSUS classification (8541.10.0050).

Q: Is the DO-35 package identical between both parts?

A: Yes. Both parts use the DO-204AH, DO-35 axial package configuration. Physical dimensions and lead spacing are identical, supporting direct board-level substitution without layout modification.

Q: What is the difference in reverse leakage current between these parts?

A: The 1N4697-TP specifies 1 µA @ 7.6 V reverse leakage. The BZX79C10 specifies 200 nA @ 7 V reverse leakage. The BZX79C10 exhibits lower reverse leakage current, which is a performance advantage in low-current applications.
