1N5262B-TP Equivalent & Substitute Parts

Part Overview

The 1N5262B-TP is a Zener diode rated at 51 V nominal voltage with 500 mW power dissipation in a DO-35 through-hole package. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete status and limited ongoing availability from the original manufacturer, identifying equivalent substitute parts is necessary for design continuity, production planning, and long-term supply chain management. Substitute parts must maintain identical electrical specifications and package compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N5262B-TP is determined by strict equivalence across the following critical parameters:

• Zener Voltage (Vz): 51 V nominal with ±5% tolerance
• Power Dissipation: 500 mW maximum
• Impedance (Zzt): 125 Ohms maximum
• Reverse Leakage Current: 100 nA @ 39 V
• Forward Voltage: 1.1 V maximum @ 200 mA
• Package Type: DO-35 through-hole axial configuration
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity: MSL 1 (Unlimited)

The substitute part 1N5262B-TAP meets all electrical and mechanical specifications required for direct replacement. Both parts share identical base product number (1N5262) and maintain full parameter compatibility. The primary difference is packaging format (Tape & Box versus bulk) and product status (Active versus Obsolete).

Frequently Asked Questions (FAQ)

Q: Can the 1N5262B-TAP be used as a direct replacement for the 1N5262B-TP without circuit modification?

A: Yes. The 1N5262B-TAP is electrically and mechanically equivalent. All critical parameters—zener voltage, power dissipation, impedance, leakage current, and forward voltage—are identical. The DO-35 through-hole package is identical, requiring no PCB layout changes.

Q: What is the difference between the 1N5262B-TP and 1N5262B-TAP part numbers?

A: The primary difference is packaging format. The -TP designation indicates bulk packaging, while -TAP indicates Tape & Box (TB) packaging. Electrically and functionally, both parts are identical. The -TAP variant is supplied by Vishay and maintains Active product status.

Q: Does the extended operating temperature range of the 1N5262B-TAP affect compatibility?

A: No. The substitute part's operating range (-65°C ~ 175°C) encompasses the original part's range (-55°C ~ 150°C). This extended range provides additional thermal margin and does not compromise compatibility in applications designed for the original specifications.

Q: Are there compliance or certification differences between the two parts?

A: Both parts are ROHS3 Compliant and REACH Unaffected. The 1N5262B-TAP carries AEC-Q101 automotive qualification, indicating enhanced reliability testing. This additional qualification does not affect compatibility and may provide additional assurance for critical applications.

Q: What is the significance of the base product number 1N5262?

A: The base product number 1N5262 identifies the core diode design and electrical specifications. Both the -TP and -TAP variants share this base number, confirming they are variants of the same fundamental component with identical electrical performance.

Q: Can the 1N5262B-TAP be used in high-reliability or automotive applications?

A: The 1N5262B-TAP carries AEC-Q101 automotive qualification, indicating suitability for automotive-grade applications. Both parts meet ROHS3 compliance requirements for regulated industries.

Q: Is there a performance difference in zener voltage tolerance between the two parts?

A: No. Both parts maintain ±5% tolerance on the 51 V nominal zener voltage, ensuring identical voltage regulation performance and circuit behavior.
