MBRX02530-TP Equivalent & Substitute Parts

Part Overview

The MBRX02530-TP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 30V DC reverse voltage and 250mA average rectified current in a surface mount SOD-323 package. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design requirements and procurement needs. Substitute parts must maintain electrical compatibility within the specified voltage and current parameters while accommodating variations in forward voltage characteristics and reverse leakage specifications.

Substitute Part Grouping Explanation

Substitution of the MBRX02530-TP is determined by the following critical parameters:

Mandatory Compatibility Criteria:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 30V
Package / Case: Must be SC-76, SOD-323 (surface mount)
Technology: Must be Schottky diode
Mounting Type: Must be Surface Mount

Functional Compatibility Criteria:

Current - Average Rectified (Io): Substitute parts rated at 200mA or higher accommodate the 250mA requirement with appropriate thermal management considerations
Voltage - Forward (Vf): Substitute parts with forward voltage specifications between 430mV and 800mV at their rated currents are functionally compatible
Speed: Fast Recovery (≤500ns) or Small Signal characteristics are acceptable for the application
Operating Temperature Range: Substitute parts with maximum junction temperatures of 125°C or 150°C are compatible

Compliance Criteria:

RoHS3 Compliance: Required
Moisture Sensitivity Level (MSL): Level 1 (Unlimited) preferred
ECCN and HTSUS classifications must match or be equivalent

Substitute parts are grouped into two categories: direct current-rated substitutes (200mA-350mA range) and higher current-rated substitutes (500mA-1A range). Both categories maintain the 30V reverse voltage specification and SOD-323 package requirement.

Engineering Selection Recommendations

Direct Current-Rated Substitutes (200mA Category):

The 1PS76SB10,115 and 1PS76SB10,135 (Nexperia) are active equivalents with identical electrical specifications. Both are AEC-Q101 qualified automotive-grade components with RoHS3 compliance. The 200mA current rating is lower than the original 250mA specification; these parts are suitable for applications where the actual operating current does not exceed 200mA. The BAT5403WE6327HTSA1 (Infineon) provides equivalent 200mA current rating with extended maximum junction temperature of 150°C, matching the original part's thermal capability.

The CUS521,H3F (Toshiba) offers 200mA current rating with forward voltage of 500mV at 200mA, closely matching the original part's 550mV specification at 250mA. This part is suitable for direct substitution in applications with current requirements up to 200mA.

Higher Current-Rated Substitutes (350mA–1A Category):

The SD103BWS-7-F (Diodes Incorporated) provides 350mA current rating with fast recovery characteristics matching the original part's speed specification. This part accommodates the original 250mA requirement with additional current margin.

The PMEG3005AEA,115 (Nexperia) and PMEG3010BEA,115 (Nexperia) offer 500mA and 1A current ratings respectively, both with fast recovery speed characteristics and 150°C maximum junction temperature. These parts provide substantial current margin above the original 250mA specification and are suitable for applications requiring higher current capacity or thermal headroom.

Compliance and Availability:

All substitute parts maintain RoHS3 compliance, MSL Level 1 moisture sensitivity, and EAR99 export classification. The Nexperia parts (1PS76SB10 variants, PMEG3005AEA,115, PMEG3010BEA,115) demonstrate the highest inventory availability (13,750–33,688 units). The Infineon BAT5403WE6327HTSA1 and Diodes Incorporated SD103BWS-7-F are also well-stocked (19,016 and 64,880 units respectively).

Frequently Asked Questions (FAQ)

Q: Can the 1PS76SB10,115 or 1PS76SB10,135 directly replace the MBRX02530-TP?

A: These Nexperia parts are functionally compatible for applications where the actual operating current does not exceed 200mA. Both maintain the 30V reverse voltage rating and SOD-323 package. The 200mA current rating is lower than the original 250mA specification. Verify that your application's maximum current requirement is within the 200mA limit before substitution.

Q: What is the difference between the 1PS76SB10,115 and 1PS76SB10,135?

A: Both parts are electrically identical with the same base product number (1PS76SB10). The suffix designations (,115 and ,135) indicate different packaging or tape configurations. Electrical specifications, current ratings, and thermal characteristics are equivalent. Selection between these variants depends on packaging and supply chain requirements.

Q: Why do some substitute parts have lower current ratings (200mA) than the original (250mA)?

A: The MBRX02530-TP is obsolete, and direct 250mA equivalents in SOD-323 packaging are limited. The 200mA-rated substitutes (1PS76SB10 variants, BAT5403WE6327HTSA1, CUS521,H3F) maintain the 30V voltage specification and SOD-323 package. These parts are suitable if your application's actual operating current is 200mA or lower. For applications requiring the full 250mA capacity, higher-rated substitutes (SD103BWS-7-F at 350mA, PMEG3005AEA,115 at 500mA, or PMEG3010BEA,115 at 1A) are recommended.

Q: What is the significance of "Fast Recovery" versus "Small Signal" speed classifications?

A: Fast Recovery (≤500ns) diodes are optimized for applications requiring rapid switching and low reverse recovery time, typically in power conversion circuits. Small Signal (≤200mA) diodes are optimized for low-current signal applications. The original MBRX02530-TP specifies Fast Recovery characteristics. Substitute parts with either Fast Recovery or Small Signal classifications are compatible, as both meet the switching speed requirements for SOD-323 Schottky diodes in typical applications.

Q: Are the higher current-rated substitutes (PMEG3005AEA,115 at 500mA and PMEG3010BEA,115 at 1A) suitable for the original application?

A: Yes. These parts maintain the 30V reverse voltage rating, SOD-323 package, and fast recovery speed characteristics. The higher current ratings (500mA and 1A) provide additional capacity margin above the original 250mA specification. These parts are suitable for direct substitution and offer thermal and current headroom for applications with potential future current increases or thermal stress conditions.

Q: What is the impact of forward voltage differences between substitute parts?

A: Forward voltage variations affect power dissipation and thermal performance. The original MBRX02530-TP specifies 550mV at 250mA. Substitute parts range from 430mV (PMEG3005AEA,115) to 800mV (1PS76SB10 variants). Lower forward voltage reduces power loss and heat generation. Higher forward voltage increases power dissipation. For applications sensitive to power efficiency or thermal management, select substitutes with forward voltage specifications closest to the original part or lower.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain RoHS3 compliance and are suitable for applications with RoHS requirements. All parts also maintain MSL Level 1 (Unlimited) moisture sensitivity classification and EAR99 export control status, matching the original part's compliance profile.

Q: What packaging options are available for substitute parts?

A: All substitute parts are supplied in SOD-323 surface mount package, matching the original MBRX02530-TP package specification. Packaging formats vary: some are supplied in Cut Tape (CT) & Digi-Reel® format, while others are supplied in Tape & Reel (TR) format. Verify packaging compatibility with your procurement and assembly processes before final part selection.

Q: Can the CUS521,H3F (Toshiba) substitute for the MBRX02530-TP?

A: Yes. The CUS521,H3F maintains the 30V reverse voltage rating, 200mA current rating, and SOD-323 package. The forward voltage specification of 500mV at 200mA closely matches the original part's 550mV at 250mA. This part is suitable for applications where the actual operating current does not exceed 200mA. The maximum junction temperature is 125°C, which is lower than the original part's 150°C specification.
