RS402L Bridge Rectifier Single Phase 100V 4A Equivalent & Substitute Parts

Part Overview

The RS402L is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 100V peak reverse voltage and 4A average rectified current in a 4-SIP through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. Active alternatives from Comchip Technology maintain electrical compatibility while offering improved product status and compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RS402L is determined by the following criteria:

Mandatory Compatibility Parameters:

Diode Type: Single Phase
Technology: Standard
Voltage - Peak Reverse (Max): 100 V minimum
Mounting Type: Through Hole
Package / Case: 4-SIP form factor

Current Rating Consideration: Substitute parts must meet or exceed the 4A average rectified current specification. Parts with higher current ratings (4.2A, 6A, 8A) are electrically compatible and function as direct substitutes in applications designed for the RS402L.

Thermal and Leakage Parameters: Operating temperature range and reverse leakage current specifications of substitute parts must not degrade circuit performance. All listed substitutes maintain compatibility within these parameters.

Engineering Selection Recommendations

GBU401-G provides the closest electrical match to RS402L with identical 4A current rating and 100V peak reverse voltage. This part is recommended for direct replacement in applications requiring exact current specifications. Active product status and ROHS3 compliance ensure long-term availability and regulatory alignment.

GBU2501-G offers 4.2A current capacity with extended operating temperature range to 150°C. This part is suitable for applications where marginal current headroom is beneficial without thermal derating concerns.

GBU601-G and GBU801-G provide higher current ratings (6A and 8A respectively) and are applicable in designs where the RS402L current specification represents a minimum requirement. Both parts maintain 100V peak reverse voltage compatibility and offer superior thermal performance through extended operating temperature ranges.

All substitute parts carry ROHS3 compliance certification, addressing regulatory requirements that the obsolete RS402L cannot satisfy. Product status classification as Active ensures continued manufacturing support and procurement availability.

Frequently Asked Questions (FAQ)

Q: Can GBU801-G replace RS402L in any application? A: GBU801-G is electrically compatible as a substitute. The 8A current rating exceeds the RS402L specification, making it suitable for applications where the original 4A rating is a minimum requirement. Physical package compatibility (4-SIP through-hole) is maintained.

Q: What is the primary reason to substitute RS402L? A: RS402L is classified as obsolete. Comchip Technology GBU-series parts provide active, in-production alternatives with identical voltage ratings, compatible current specifications, and improved compliance certifications.

Q: Are there thermal performance differences between RS402L and substitute parts? A: Substitute parts from Comchip Technology support extended operating temperature ranges (-55°C to 150°C) compared to RS402L (-55°C to 125°C). This provides additional thermal margin in high-temperature applications.

Q: Is package compatibility guaranteed between RS402L and GBU-series substitutes? A: Both RS402L and all GBU-series substitutes use 4-SIP through-hole packages. Physical footprint and pin configuration are compatible for direct board-level substitution.

Q: Which substitute part should be selected for new designs? A: GBU401-G is recommended for new designs requiring exact 4A current specification. GBU601-G or GBU801-G are preferred if design margins or thermal performance improvements are priorities. All three parts are active products with ROHS3 compliance.

Q: Does reverse leakage current variation affect substitution suitability? A: All substitute parts maintain reverse leakage specifications within acceptable engineering tolerances for single-phase bridge rectifier applications. GBU801-G offers superior leakage performance at 5 µA compared to 10 µA in other parts.
