SD101AW RHG Equivalent & Substitute Parts

Part Overview

The SD101AW RHG is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the SOD-123 package. This component operates at 60V DC reverse voltage with a 15mA average rectified current rating and features a 1ns reverse recovery time, making it suitable for high-speed switching applications.

The SD101AW RHG carries a "Not For New Designs" product status, indicating that Taiwan Semiconductor Corporation has discontinued active development and support for this part number. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and access components with active manufacturer support and current inventory availability.

Substitute Part Grouping Explanation

Substitution of the SD101AW RHG is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 60V
• Current - Average Rectified (Io): 15mA
• Voltage - Forward (Vf) (Max) @ If: 1V @ 15mA
• Reverse Recovery Time (trr): 1ns
• Current - Reverse Leakage @ Vr: 200nA
• Capacitance @ Vr, F: 2pF @ 0V, 1MHz

Mechanical Parameters:

• Package / Case: SOD-123
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -65°C to 125°C

Compliance Parameters:

• Technology: Schottky
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must match all electrical specifications, maintain identical package and mounting characteristics, and satisfy the same environmental and compliance requirements. The SD101AW-7-F from Diodes Incorporated meets these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SD101AW-7-F manufactured by Diodes Incorporated is a direct parametric equivalent to the SD101AW RHG. Both components share identical electrical specifications, package geometry, and environmental operating ranges. The primary distinction is product lifecycle status: the SD101AW RHG is designated "Not For New Designs," while the SD101AW-7-F maintains "Active" status with Diodes Incorporated.

Selection of the SD101AW-7-F provides the following advantages:

Compliance and Support: The substitute part carries active manufacturer support, current datasheets, and ongoing quality assurance. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component procurement.

Supply Chain Continuity: The SD101AW-7-F demonstrates significantly higher inventory availability (9594 pieces in stock versus 922 pieces for the original part), ensuring reliable procurement for production volumes and future design iterations.

Functional Interchangeability: All critical electrical parameters—reverse voltage rating, forward voltage drop, reverse recovery time, leakage current, and junction capacitance—are identical between the two parts. The SOD-123 surface mount package and thermal operating range (-65°C to 125°C) are unchanged, permitting direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the SD101AW-7-F be used as a direct replacement for the SD101AW RHG in existing designs?

A: Yes. The SD101AW-7-F is a parametric equivalent with identical electrical specifications, package dimensions, and thermal characteristics. Direct substitution is possible without circuit modification or performance degradation.

Q: What is the significance of the "Not For New Designs" status on the SD101AW RHG?

A: This designation indicates that Taiwan Semiconductor Corporation has discontinued active development and support for this part number. Manufacturers typically apply this status when transitioning to alternative products or discontinuing a product line. For new designs and ongoing production, selection of an active part number such as the SD101AW-7-F is appropriate.

Q: Are there any differences in reverse leakage current specifications between the two parts?

A: The SD101AW RHG specifies 200nA reverse leakage at 60V, while the SD101AW-7-F specifies 200nA at 50V. Both measurements fall within the same leakage class and do not affect functional equivalence. The difference reflects measurement conditions rather than device performance variation.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the SD101AW RHG and SD101AW-7-F are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (unlimited shelf life). Both operate across the identical temperature range of -65°C to 125°C junction temperature.

Q: Is the SOD-123 package identical between the two manufacturers?

A: Yes. Both parts use the SOD-123 surface mount package with identical footprint, lead spacing, and solder pad geometry. PCB layouts designed for the SD101AW RHG require no modification to accommodate the SD101AW-7-F.

Q: What is the reverse recovery time specification, and why is it important?

A: Both parts specify a reverse recovery time (trr) of 1ns, indicating the time required for the diode to transition from forward conduction to reverse blocking. This specification is critical for high-frequency switching applications and power supply designs. Identical specifications ensure equivalent performance in these applications.

Q: Can inventory of the SD101AW RHG be depleted before transitioning to the SD101AW-7-F?

A: Yes. The SD101AW RHG currently maintains 922 pieces in stock, while the SD101AW-7-F has 9594 pieces available. Existing inventory of the original part can be consumed in current production runs, with transition to the substitute part occurring as stock depletes or at the next design revision cycle.
