RB560SS-40T2R Equivalent & Substitute Parts

Part Overview

The RB560SS-40T2R is a Schottky diode manufactured by Rohm Semiconductor, rated for 40 V DC reverse voltage with 500 mA average rectified current. This component is designed for surface mount applications in the 0603 (1608 Metric) package format with KMD2 supplier device packaging. The part is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and procurement needs.

Substitute Part Grouping Explanation

Substitution of the RB560SS-40T2R is determined by electrical and mechanical parameter equivalence. The primary substitute, RB560VM-40TE-17, maintains identical electrical specifications across all critical parameters: 40 V reverse voltage rating, 500 mA average rectified current, 640 mV forward voltage drop at 500 mA, fast recovery speed characteristics, and 40 µA reverse leakage current at rated voltage. Both components share the same base product number (RB560) and operate within the same junction temperature range of 150°C maximum.

The key differentiator between these parts is the package format and supplier device packaging designation. The RB560SS-40T2R uses KMD2 packaging in 0603 (1608 Metric) format, while the RB560VM-40TE-17 uses UMD2 packaging in SC-90/SOD-323F format. Both are surface mount technologies with equivalent electrical performance.

Substitution eligibility is based on the following parameters:

Voltage - DC Reverse (Vr) (Max): 40 V
Current - Average Rectified (Io): 500 mA
Voltage - Forward (Vf) (Max) @ If: 640 mV @ 500 mA
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 40 µA @ 40 V
Technology: Schottky
Operating Temperature - Junction: 150°C

Engineering Selection Recommendations

The RB560VM-40TE-17 is an active substitute for the obsolete RB560SS-40T2R. Both components are manufactured by Rohm Semiconductor and maintain identical electrical specifications for voltage, current, forward voltage drop, recovery speed, and leakage characteristics. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary consideration for selection is package compatibility. The RB560SS-40T2R uses 0603 (1608 Metric) KMD2 packaging, while the RB560VM-40TE-17 uses SC-90/SOD-323F UMD2 packaging. PCB layout and footprint requirements must accommodate the different package dimensions. The RB560VM-40TE-17 is available in active production status with higher inventory availability (4200 pieces), compared to the obsolete RB560SS-40T2R (874 pieces remaining).

Frequently Asked Questions (FAQ)

Question	Answer
Can the RB560VM-40TE-17 directly replace the RB560SS-40T2R in existing designs?	Electrical substitution is valid based on identical voltage, current, forward voltage, and leakage specifications. However, package format differs (0603 KMD2 versus SC-90/SOD-323F UMD2), requiring PCB footprint verification and potential layout modifications.
What are the key electrical parameters that define substitution eligibility?	Substitution is determined by: 40 V reverse voltage rating, 500 mA average rectified current, 640 mV forward voltage at 500 mA, fast recovery speed (≤ 500ns for currents > 200mA), 40 µA reverse leakage at 40 V, and 150°C maximum junction temperature.
Are there compliance differences between these parts?	Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both components.
What is the primary reason for substitution?	The RB560SS-40T2R is classified as obsolete. The RB560VM-40TE-17 is an active production equivalent with identical electrical performance and higher inventory availability.
How do the package formats differ?	The RB560SS-40T2R uses 0603 (1608 Metric) package with KMD2 supplier designation. The RB560VM-40TE-17 uses SC-90/SOD-323F package with UMD2 supplier designation. Both are surface mount technologies with different physical dimensions.
Is the RB560VM-40TE-17 available in different packaging options?	The RB560VM-40TE-17 is supplied in Cut Tape (CT) and Digi-Reel® formats, with Tape & Reel (TR) packaging available. This provides flexibility for different procurement and assembly requirements.
