S30480 Equivalent & Substitute Parts Reference

Part Overview

The S30480 from Microchip Technology is a diode rectifier categorized under Diodes, Rectifiers. It features an 800 V maximum reverse voltage, 40A average rectified current, and is housed in the DO-203AB (DO-5) stud mount package. The part is designated as active and utilizes standard recovery technology. Alternative models are necessary in cases where compliance requirements, availability, or changes in sourcing dictate replacement while retaining equivalent form, fit, and function within the specified electrical and mechanical constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on the following electrical and mechanical parameters: maximum reverse voltage (Vr), average rectified current (Io), forward voltage (Vf) at specified current (If), recovery speed classification, mounting type, package/case form factor, and operating temperature range. Only parts matching or exceeding these criteria, and within the same package type, are listed as substitutes.

Key parameters ensuring form, fit, and function equivalence:

• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io)
• Voltage - Forward (Vf) (Max) @ If
• Speed (Recovery Classification)
• Mounting Type
• Package / Case
• Operating Temperature - Junction

Parameter Comparison

Engineering Selection Recommendations

Selection between the S30480 and the substitute VS-42HF80 should consider RoHS and REACH compliance requirements. The S30480 is RoHS non-compliant, while the VS-42HF80 is ROHS3 compliant. Both parts have an active status and are REACH unaffected. For applications with mandatory RoHS compliance, the VS-42HF80 should be selected. Both parts are active and within the same form factor and electrical rating range.

Frequently Asked Questions (FAQ)

Q: What are the principal criteria for selecting a substitute part in this diode rectifier category?
A: Substitution is determined by matching voltage rating, average rectified current, package/case type, mounting method, and recovery speed classification.

Q: Does the mounting style or package affect compatibility?
A: Both parts use the DO-203AB (DO-5) stud mount package, ensuring mechanical compatibility for stud mount hardware and enclosure design.

Q: How does RoHS status impact part substitution?
A: Where RoHS compliance is required, only ROHS3 compliant substitutes such as the VS-42HF80 are suitable. Non-compliant parts like the S30480 must be avoided in regulated markets.

Q: Are there differences in electrical performance significant for substitution?
A: Electrical parameters such as voltage rating, current rating, forward voltage, and speed are matched within the provided data. Small variations in maximum forward voltage and operating temperature should be compared to system requirements.

Q: Are both parts currently available and active?
A: Both S30480 and VS-42HF80 are listed as active and have confirmed inventory in stock based on the provided inputs.
