Engineering Selection Recommendations

All three substitute parts—RGL34K-E3/83, RGL34K-E3/98, and RGL34KHE3/98—meet the electrical requirements of the GL34K-TP across voltage, current, temperature, and leakage specifications. The substitutes are manufactured by Vishay General Semiconductor - Diodes Division and maintain active product status, ensuring long-term availability and supply chain stability.

RGL34KHE3/98 is the preferred substitute, offering the highest inventory availability (42,348 pcs) and active product status. This part maintains all critical electrical parameters while providing enhanced recovery characteristics (Fast Recovery =< 500ns versus Standard Recovery >500ns) and documented reverse recovery time (250 ns).

RGL34K-E3/98 and RGL34K-E3/83 are functionally equivalent alternatives with identical electrical specifications and active status. Both parts provide adequate inventory levels and are suitable for applications where the GL34K-TP was previously specified.

All substitute parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 and HTSUS 8541.10.0070, matching the regulatory profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can RGL34K-E3/83, RGL34K-E3/98, and RGL34KHE3/98 be used interchangeably with GL34K-TP?

A: Yes. All three parts meet the electrical specifications of the GL34K-TP, including 800 V reverse voltage, 500 mA average rectified current, 1.3 V forward voltage at 500 mA, and 5 µA reverse leakage at 800 V. Operating temperature range (-65°C to 175°C) is identical across all parts.

Q: What is the difference between the GL34K-TP package and the substitute parts?

A: The GL34K-TP uses a Mini MELF package (DO-213AC, SOD-80). The substitute parts use DO-213AA (Glass) package configuration. Both are Surface Mount packages with compatible footprints for standard PCB assembly processes.

Q: Why do the substitute parts have faster recovery times?

A: The substitute parts are classified as Fast Recovery (≤ 500ns) with documented reverse recovery time of 250 ns, compared to the GL34K-TP Standard Recovery (>500ns). This represents an improvement in switching performance and is not a limitation for applications designed for the original component.

Q: Are there compliance or regulatory differences between GL34K-TP and the substitutes?

A: No. All parts are ROHS3 Compliant, REACH Unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.10.0070) classifications.

Q: Which substitute part should be selected for new designs?

A: RGL34KHE3/98 is recommended for new designs due to active product status, highest inventory availability (42,348 pcs), and documented performance characteristics. RGL34K-E3/98 and RGL34K-E3/83 are equivalent alternatives with adequate availability.

Q: Is PCB layout modification required when substituting GL34K-TP with RGL34K-E3/83, RGL34K-E3/98, or RGL34KHE3/98?

A: Package footprint compatibility between Mini MELF (DO-213AC) and DO-213AA (Glass) must be verified for your specific PCB design. Both are Surface Mount packages, but physical dimensions may differ. Consult package datasheets for precise footprint specifications.

Q: What is the moisture sensitivity level for all parts?

A: All parts, including GL34K-TP and the three substitutes, are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
