Engineering Selection Recommendations

Substitution should be based on product status to ensure continued availability. RB520CS-30FHT2RA is a direct parametric equivalent manufactured by Rohm Semiconductor in the same package, compliant with ROHS3 and REACH, and is active for new designs. Substitute parts such as 1SS416,L3M (Toshiba Semiconductor and Storage), NSR0230P2T5G (onsemi), and PMEG4002EL,315 (Nexperia USA Inc.) also meet RoHS and REACH requirements and remain active, making them suitable for engineering selection within the defined electrical and mechanical criteria.

Frequently Asked Questions (FAQ)

Q1: What key parameters determine whether a substitute can replace the RB520CS-30T2R?
A1: Substitution is based on technology type (Schottky), maximum DC reverse voltage, average rectified current, forward voltage characteristics, reverse leakage current, mounting type, package or case compatibility, operating temperature range, compliance (RoHS, REACH), and product availability status.

Q2: Do all substitutes fit directly in the same PCB footprint as RB520CS-30T2R?
A2: RB520CS-30FHT2RA is in the same package (VMN2/SOD-923) for direct footprint compatibility. Other substitutes use standard SOD-923 or similar packages; mechanical design review is required to ensure footprint matching on the PCB.

Q3: Is there any difference in compliance or certification among the substitutes?
A3: All listed substitute parts are ROHS3 Compliant and REACH Unaffected, with MSL of 1 (Unlimited), ensuring compatibility with global environmental and supply chain standards.

Q4: Can substitute parts be used in new designs?
A4: The RB520CS-30T2R is Not For New Designs, while all substitute parts listed are in Active status and suitable for new design integration, subject to matching the listed parameters.

Q5: How should operating temperature be considered when selecting among substitutes?
A5: Selection should match the application requirements for maximum junction temperature as specified in the parameters for each part; substitutes are provided with their respective operating temperature ratings.
