JANS1N4460CUS/TR Equivalent & Substitute Parts

Part Overview

The JANS1N4460CUS/TR is a military-grade Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. This component operates at a nominal Zener voltage of 6.2 V with 1.5 W maximum power dissipation and ±2% tolerance. The part is qualified to MIL-PRF-19500/406 military standards and is currently in active production status. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or supply chain continuity while maintaining full compliance with application specifications.

Engineering Selection Recommendations

The 1N4460CUS/TR is a direct parametric equivalent to the JANS1N4460CUS/TR. Both components are manufactured by Microchip Technology and share identical electrical specifications, mechanical packaging, and operating characteristics. The primary distinction is the military-grade designation (JAN prefix) on the JANS1N4460CUS/TR, which indicates compliance with MIL-PRF-19500/406 qualification standards.

Selection Criteria:

For applications requiring military-grade components with MIL-PRF-19500/406 qualification, the JANS1N4460CUS/TR is the specified choice. The 1N4460CUS/TR is suitable for applications where military qualification is not a contractual or regulatory requirement, provided all electrical and mechanical parameters remain within the specified ranges.

Both parts are in active production status and available in Tape & Reel packaging. Component selection should be based on application compliance requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 1N4460CUS/TR be used as a direct replacement for the JANS1N4460CUS/TR?

A: The 1N4460CUS/TR is electrically and mechanically equivalent to the JANS1N4460CUS/TR. However, the JANS variant carries military-grade qualification (MIL-PRF-19500/406). Substitution is permissible only in applications where military qualification is not a contractual or regulatory requirement.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact equivalence across nominal Zener voltage (6.2 V), tolerance (±2%), maximum power (1.5 W), impedance (4 Ohms maximum), reverse leakage current (10 µA @ 3.72 V), forward voltage (1.5 V @ 1 A), operating temperature range (-65°C to 175°C), and package configuration (SQ-MELF, A / D-5A).

Q: Are both parts available in the same packaging format?

A: Both the JANS1N4460CUS/TR and 1N4460CUS/TR are supplied in Tape & Reel (TR) packaging with D-5A surface mount configuration. No packaging conversion is required for substitution.

Q: What is the difference between the JANS and non-JANS part numbers?

A: The JANS prefix indicates military-grade qualification to MIL-PRF-19500/406 standards. All electrical and mechanical parameters are identical between the two variants. The distinction is compliance-based rather than performance-based.

Q: Can these parts be used interchangeably in high-reliability applications?

A: In applications where military qualification is specified, only the JANS1N4460CUS/TR meets contractual requirements. In applications where military qualification is not specified, both parts meet the stated electrical and mechanical requirements. Application documentation should be reviewed to determine qualification requirements.
