S4M R6 Equivalent & Substitute Parts

Part Overview

The S4M R6 is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 4 A average rectified current in a surface mount DO-214AB (SMC) package. This component is classified as discontinued at DiGi Electronics, necessitating identification of equivalent alternatives for ongoing design support and procurement. The part is manufactured by Taiwan Semiconductor Corporation and complies with RoHS3 and REACH standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S4M R6 is determined by electrical and mechanical parameter equivalence. The primary substitution candidate is the S4M, which shares identical electrical specifications across all critical parameters: 1000 V reverse voltage rating, 4 A average rectified current, 1.15 V forward voltage drop at 4 A, 1.5 µs reverse recovery time, 10 µA reverse leakage current at 1000 V, and 60 pF capacitance at 4 V and 1 MHz. Both parts utilize the DO-214AB (SMC) surface mount package and operate across the same temperature range of -55°C to 150°C. The key differentiator is product status and packaging format: the S4M R6 is discontinued, while the S4M is active and available in Tape & Reel (TR) packaging. Both parts maintain identical RoHS3 compliance and MSL rating of 1 (Unlimited).

Parameter Comparison

Engineering Selection Recommendations

The S4M is a direct electrical and mechanical equivalent to the S4M R6. Selection of the S4M as a substitute is supported by complete parameter equivalence across all electrical specifications, identical package geometry (DO-214AB, SMC), and matching compliance certifications (RoHS3, REACH Unaffected). The S4M maintains active product status with higher inventory availability (13,780 pieces in stock versus 866 pieces for the discontinued S4M R6). The S4M is supplied in standard Tape & Reel (TR) packaging, which is the conventional format for high-volume surface mount assembly operations. Both parts carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, confirming regulatory equivalence. The substitution is appropriate for all applications where the S4M R6 was originally specified.

Frequently Asked Questions (FAQ)

Q: Are the S4M R6 and S4M electrically identical?

A: Yes. Both parts share identical electrical parameters: 1000 V reverse voltage, 4 A average rectified current, 1.15 V forward voltage drop at 4 A, 1.5 µs reverse recovery time, and 10 µA reverse leakage current at 1000 V. All switching and thermal characteristics are equivalent.

Q: What is the difference between S4M R6 and S4M?

A: The primary differences are product status and packaging format. The S4M R6 is discontinued at DiGi Electronics, while the S4M is active. The S4M is supplied in Tape & Reel (TR) packaging, which is standard for surface mount assembly. The electrical and mechanical specifications are identical.

Q: Can the S4M be used as a direct replacement in existing designs?

A: Yes. The S4M is a direct replacement for the S4M R6. Both parts use the DO-214AB (SMC) surface mount package with identical pin configuration and footprint. No design modifications are required.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are RoHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications. Regulatory and environmental compliance is equivalent.

Q: What is the MSL rating for these parts?

A: Both the S4M R6 and S4M carry an MSL rating of 1 (Unlimited), indicating unlimited shelf life and no moisture sensitivity restrictions during storage or handling.

Q: Is the S4M available in higher quantities?

A: Yes. The S4M has significantly higher inventory availability with 13,780 pieces in stock compared to 866 pieces for the discontinued S4M R6, making it the preferred choice for ongoing procurement.
