Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STPS30L60CW is determined by the following mandatory parameters:

• Diode Configuration: Must be 1 Pair Common Cathode
• Technology: Must be Schottky
• Voltage - DC Reverse (Vr) (Max): Must be 60 V
• Current - Average Rectified (Io) (per Diode): Must be 15 A or greater
• Mounting Type: Must be Through Hole
• Package / Case: Must be TO-247-3

The substitute parts identified below satisfy these core electrical and mechanical requirements. Variations in secondary parameters such as forward voltage drop, reverse leakage current, and temperature operating range are permissible within the scope of component substitution, provided the primary electrical ratings and physical packaging remain equivalent.

Engineering Selection Recommendations

STPS30L60CW (Primary Component)

The STPS30L60CW remains the preferred selection when available. This component carries Active product status, ROHS3 compliance certification, and meets all specified electrical parameters with a forward voltage drop of 600 mV at 15 A and reverse leakage current of 480 µA at 60 V.

30CPQ060 (Substitute - Limited Applicability)

The 30CPQ060 is electrically equivalent to the STPS30L60CW with identical voltage ratings, current capacity, and forward voltage characteristics. However, this component carries Obsolete product status and is RoHS non-compliant. Selection of this substitute is appropriate only in applications where RoHS compliance is not a regulatory requirement and where extended supply availability from existing inventory is acceptable.

MBR3060WT (Substitute - Conditional Applicability)

The MBR3060WT is manufactured by SMC Diode Solutions and maintains Active product status with ROHS3 compliance. This component satisfies the core electrical and mechanical requirements of the STPS30L60CW. The forward voltage drop is specified at 770 mV at 15 A, representing a 170 mV increase relative to the primary component. The reverse leakage current is specified at 5 mA at 60 V, which is significantly higher than the STPS30L60CW at 480 µA. Selection of the MBR3060WT is appropriate when thermal dissipation and leakage current characteristics are within acceptable design margins for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 30CPQ060 be used as a direct replacement for the STPS30L60CW in new designs?

A: The 30CPQ060 is electrically equivalent and mechanically compatible. However, this component is classified as Obsolete and is RoHS non-compliant. New designs should not incorporate obsolete components. The 30CPQ060 is suitable only for legacy system maintenance or repair applications where RoHS compliance is not mandated.

Q: What is the impact of the higher forward voltage drop in the MBR3060WT?

A: The MBR3060WT exhibits a forward voltage drop of 770 mV at 15 A compared to 600 mV for the STPS30L60CW. This 170 mV difference results in increased power dissipation in the diode. Thermal analysis of the target application is required to confirm that junction temperature remains within the 150°C maximum operating limit.

Q: Are all substitute parts pin-compatible with the STPS30L60CW?

A: All substitute parts are packaged in the TO-247-3 case with identical pin configuration and mechanical dimensions. Pin-for-pin compatibility is confirmed for all listed substitutes.

Q: What is the significance of the higher reverse leakage current in the MBR3060WT?

A: The MBR3060WT exhibits reverse leakage current of 5 mA at 60 V, compared to 480 µA for the STPS30L60CW. This tenfold increase in leakage current may impact circuit performance in applications sensitive to standby power consumption or bias current stability. Circuit-level analysis is required to determine acceptability in the target application.

Q: Which substitute part is recommended for new production designs?

A: The MBR3060WT is the recommended substitute for new production designs. This component carries Active product status, ROHS3 compliance certification, and maintains adequate electrical performance within the specified parameter ranges. The 30CPQ060 should not be selected for new designs due to its Obsolete status and RoHS non-compliance.

Q: Are there any compliance or regulatory differences between the substitute parts?

A: The STPS30L60CW and MBR3060WT are both ROHS3 compliant. The 30CPQ060 is RoHS non-compliant and should not be used in applications subject to RoHS regulatory requirements. All three components are classified as REACH Unaffected or REACH Affected, with ECCN classification EAR99 and HTSUS code 8541.10.0080.
