Engineering Selection Recommendations

The GL41T-E3/1 is classified as obsolete and should be replaced with an active equivalent for new designs and production continuity. All four substitute parts—GL41T-E3/96, GL41T-E3/97, GL41THE3/96, and GL41THE3/97—are active products manufactured by Vishay General Semiconductor - Diodes Division and maintain full electrical and mechanical compatibility with the original specification.

Direct Manufacturer Substitutes (Tape & Reel Packaging): GL41T-E3/96 and GL41T-E3/97 are supplied in Tape & Reel format and carry active product status. These parts are suitable for automated assembly processes and high-volume production environments.

Parametric Equivalent Substitutes: GL41THE3/96 and GL41THE3/97 are parametric equivalents with active product status. These parts maintain identical electrical performance and mechanical compatibility.

All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard handling and storage procedures. Selection between available substitutes should be based on packaging format requirements and supply availability.

Frequently Asked Questions (FAQ)

Q: Can GL41T-E3/96 or GL41T-E3/97 be used as direct replacements for GL41T-E3/1?

A: Yes. GL41T-E3/96 and GL41T-E3/97 are direct manufacturer substitutes with identical electrical specifications (1300 V reverse voltage, 1 A average rectified current, 1.2 V forward voltage at 1 A) and mechanical compatibility (DO-213AB MELF glass package, surface mount). The primary difference is product status (active versus obsolete) and packaging format (Tape & Reel).

Q: What is the difference between GL41T-E3/97 and GL41THE3/97?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference lies in the part number designation and packaging format.
