Engineering Selection Recommendations

1N5398GP-TP is the primary substitute for the obsolete 1N5398-TP. Both parts are manufactured by Micro Commercial Co and share identical electrical ratings for reverse voltage, average rectified current, and operating temperature range. The 1N5398GP-TP maintains active product status, ensuring long-term availability and supply chain continuity. Forward voltage specification is slightly higher (1.4 V versus 1.1 V), which remains within acceptable rectifier diode performance parameters. This part is available in Tape & Reel packaging, suitable for automated assembly processes.

PG158_R2_00001 is a parametric equivalent from Panjit International Inc. that meets all critical electrical and mechanical requirements. This part offers superior reverse leakage characteristics (1 µA versus 5 µA) and maintains active product status. Selection of this alternative is appropriate when supply diversification or specific performance advantages are required. The part is also available in Tape & Reel packaging.

Both substitute parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications, ensuring regulatory and trade compliance equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can 1N5398GP-TP be used as a direct replacement for 1N5398-TP?

A: Yes. Both parts share identical voltage ratings (800 V), current ratings (1.5 A), temperature range (-55°C to 150°C), and package configuration (DO-15 axial through-hole). The 1N5398GP-TP is the active equivalent from the same manufacturer.

Q: What is the difference in forward voltage between the substitute parts?

A: The 1N5398-TP and PG158_R2_00001 specify 1.1 V forward voltage at 1.5 A, while 1N5398GP-TP specifies 1.4 V at the same current. All values fall within standard rectifier diode performance ranges and do not affect functional compatibility in typical applications.

Q: Are there packaging differences between the main part and substitutes?

A: The original 1N5398-TP is supplied in bulk packaging. Both substitute parts (1N5398GP-TP and PG158_R2_00001) are supplied in Tape & Reel (TR) format, which is standard for automated assembly. The physical component dimensions and electrical characteristics remain identical.

Q: Does reverse leakage current variation affect part selection?

A: The PG158_R2_00001 exhibits lower reverse leakage (1 µA versus 5 µA at 800 V). This represents improved performance and does not create compatibility issues. Applications with stringent leakage requirements may benefit from this specification.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 1N5398-TP, 1N5398GP-TP, and PG158_R2_00001 are all ROHS3 compliant, meeting current environmental and regulatory standards.

Q: Can PG158_R2_00001 be used interchangeably with 1N5398GP-TP?

A: Yes. Both parts meet identical critical electrical parameters (800 V reverse voltage, 1.5 A average rectified current) and mechanical requirements (DO-15 through-hole axial package, -55°C to 150°C operating range). Selection between these parts depends on manufacturer preference and supply chain considerations.
