MBRX130-TP Equivalent & Substitute Parts

Part Overview

The MBRX130-TP is a Schottky rectifier diode rated for 30 V DC reverse voltage and 1 A average rectified current in a surface mount SOD-123 package. Manufactured by Micro Commercial Co, this component is classified as Obsolete. Due to its obsolete status and limited availability relative to active alternatives, equivalent substitute parts from active product lines are necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRX130-TP is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Voltage - DC Reverse (Vr) (Max): 30 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Compatibility Requirements:

• Package / Case: SOD-123 or SOD-123F (compatible footprints)
• Mounting Type: Surface Mount

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must meet or exceed all electrical parameters while maintaining mechanical compatibility. Forward voltage characteristics may vary within acceptable design margins. Reverse leakage current specifications may differ between manufacturers while remaining within acceptable operating limits for the application.

Engineering Selection Recommendations

For Active Production and New Designs:

The onsemi MBR130T1G, MBR130T3G, and NRVB130T1G are the preferred substitutes for the obsolete MBRX130-TP. All three parts carry Active product status, ensuring long-term availability and supply chain stability. These parts meet all electrical requirements with equivalent or superior performance characteristics, particularly in reverse leakage current (60 µA versus 300 µA on the original part).

MBR130T1G and MBR130T3G are available in Cut Tape (CT) & Digi-Reel® packaging, while NRVB130T1G is supplied in Tape & Reel (TR) format. Selection between these three should be based on packaging and reel format requirements for your manufacturing process.

For Legacy System Support:

The SM5818PL-TP from Micro Commercial Co maintains the same manufacturer lineage as the original part and carries Not For New Designs status. This part is suitable only for replacement in existing systems where supply continuity is required. It features improved reverse leakage characteristics (100 µA) compared to the original MBRX130-TP.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and environmental compatibility with the original component.

Frequently Asked Questions (FAQ)

Q: Can the MBRX130-TP be directly replaced with MBR130T1G?

A: Yes. Both parts share identical electrical specifications for voltage rating (30 V), current rating (1 A), and package type (SOD-123). The MBR130T1G is electrically compatible and offers superior reverse leakage performance (60 µA versus 300 µA). The primary difference is product status: MBR130T1G is Active while MBRX130-TP is Obsolete.

Q: What is the difference between MBR130T1G and NRVB130T1G?

A: Both parts are manufactured by onsemi and share identical electrical specifications. The primary difference is packaging format: MBR130T1G is supplied in Cut Tape (CT) & Digi-Reel® format, while NRVB130T1G is supplied in Tape & Reel (TR) format. Selection depends on your assembly equipment and tape reel compatibility requirements.

Q: Is SM5818PL-TP suitable for new designs?

A: No. SM5818PL-TP carries Not For New Designs status and should be used only for replacement in existing systems. For new designs, use MBR130T1G, MBR130T3G, or NRVB130T1G from onsemi, which all carry Active product status.

Q: Are there package compatibility issues between SOD-123 and SOD-123F?

A: SOD-123F is a variant of the SOD-123 package. SM5818PL-TP uses SOD-123F while the original MBRX130-TP and other substitutes use standard SOD-123. Both packages are mechanically compatible for PCB footprints designed for SOD-123, though verification with your specific PCB layout is necessary.

Q: Why do the onsemi parts show lower forward voltage at 700 mA compared to the original part specification at 1 A?

A: Forward voltage specifications are measured at different current levels. The onsemi parts specify Vf at 700 mA (450 mV), while the original MBRX130-TP specifies Vf at 1 A (550 mV). Both measurements are valid at their respective test currents. The onsemi parts demonstrate superior forward voltage characteristics at the specified measurement point.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (SM5818PL-TP, MBR130T1G, MBR130T3G, and NRVB130T1G) are ROHS3 compliant and REACH unaffected, maintaining full regulatory compatibility with the original MBRX130-TP.

Q: What is the operating temperature range difference between MBRX130-TP and the substitutes?

A: The original MBRX130-TP operates from -55°C to 125°C. All substitute parts operate from -65°C to 125°C, providing an extended lower temperature operating range. This represents an improvement in thermal performance specifications.
