ZGL41-200-E3/96 Equivalent & Substitute Parts

Part Overview

The ZGL41-200-E3/96 is a Zener diode rated at 200 V, 1 W with ±10% tolerance, manufactured by Vishay General Semiconductor - Diodes Division. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement. The part is housed in a DO-213AB (MELF) surface mount package and is ROHS3 compliant. Due to its obsolete status, active production alternatives with equivalent or superior electrical characteristics are required for new designs and inventory replenishment.

Substitute Part Grouping Explanation

Substitution of the ZGL41-200-E3/96 is determined by the following critical parameters: nominal Zener voltage (200 V), maximum power dissipation capability (1 W minimum), impedance characteristics (1200 Ohms maximum), reverse leakage current specifications, forward voltage drop, operating temperature range, and surface mount package compatibility (DO-213AB/MELF).

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalents (Vishay): Parts ZGL41-200A-E3/96 and ZGL41-200A-E3/97 maintain identical electrical specifications with the exception of improved tolerance (±5% versus ±10%). These parts share the same base product number (ZGL41) and package designation, ensuring mechanical and electrical interchangeability.

Cross-Manufacturer Alternatives (Microchip Technology): Parts 1N4496US, CDLL5956C, and CDLL5956D provide equivalent or enhanced performance. These parts maintain the 200 V Zener voltage specification and surface mount package compatibility. Power ratings range from 1.25 W to 1.5 W, exceeding the original 1 W specification. Tolerance specifications range from ±1% to ±5%, providing superior voltage regulation accuracy compared to the original ±10% tolerance.

Engineering Selection Recommendations

For ROHS3 Compliance Requirements:

Select ZGL41-200A-E3/96 or ZGL41-200A-E3/97 as primary substitutes. Both parts maintain ROHS3 compliance status identical to the original ZGL41-200-E3/96. These Vishay parts are active production items with improved ±5% tolerance specification, providing superior voltage regulation accuracy while maintaining all electrical and mechanical compatibility parameters.

For Applications Without RoHS Compliance Constraints:

Microchip Technology alternatives (1N4496US, CDLL5956C, CDLL5956D) are viable substitutes. These parts offer enhanced performance characteristics including higher power ratings (1.25 W to 1.5 W) and superior tolerance specifications (±1% to ±5%). The 1N4496US provides the highest power rating at 1.5 W with extended operating temperature range (-65 to 175 °C). CDLL5956D offers the tightest tolerance specification at ±1%, suitable for precision voltage regulation applications.

For Thermal Performance Considerations:

Parts with extended operating temperature ranges (-65 to 175 °C) include 1N4496US, CDLL5956C, and CDLL5956D. These alternatives provide 25 °C additional upper temperature margin compared to the original specification (-55 to 150 °C).

For Inventory and Lead Time:

All substitute parts listed are active production items with confirmed inventory availability. ZGL41-200A-E3/97 maintains the highest inventory level at 1176 pieces.

Frequently Asked Questions (FAQ)

Q: Can ZGL41-200A-E3/96 and ZGL41-200A-E3/97 be used as direct replacements for ZGL41-200-E3/96?
