US2M-TP Equivalent & Substitute Parts

Part Overview

The US2M-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 1000 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AA (SMB) package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the US2M-TP are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 2 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Allowable Variations:

• Reverse Recovery Time (trr): Equal to or faster than specified
• Current - Reverse Leakage @ Vr: Equal to or lower than specified
• Operating Temperature - Junction: Equal to or wider range than specified
• Capacitance @ Vr, F: Not a limiting factor for substitution

Two substitute parts meet these criteria: UF2M_R1_00001 (Panjit International Inc.) and ER2M (Diotec Semiconductor).

Parameter Comparison

Engineering Selection Recommendations

US2M-TP (Primary Part): The US2M-TP is the specified component with Active product status, ROHS3 compliance, and MSL 1 rating. This part is suitable for applications requiring unlimited moisture sensitivity handling and is available in high inventory volume (17,300 pcs).

UF2M_R1_00001 (Direct Substitute): The UF2M_R1_00001 from Panjit International Inc. is electrically and mechanically equivalent to the US2M-TP. It meets all critical parameters with identical voltage, current, and forward voltage ratings. The reverse leakage current is lower (1 µA vs. 5 µA), which represents improved performance. Operating temperature range is wider (-55°C to 150°C vs. -50°C to 150°C). RoHS3 compliance and MSL 1 rating are maintained. This part is suitable for direct substitution in applications where Panjit components are acceptable.

ER2M (Parametric Equivalent): The ER2M from Diotec Semiconductor meets all critical electrical parameters with identical voltage, current, and forward voltage ratings. The reverse recovery time is faster (75 ns vs. 100 ns), providing improved switching performance. This part is RoHS3 compliant and Active status. MSL is not applicable for this part. The ER2M is suitable for substitution in applications where faster recovery characteristics are beneficial or where Diotec components are approved.

All three parts are Active, RoHS3 compliant, and suitable for surface mount assembly in DO-214AA (SMB) packages.

Frequently Asked Questions (FAQ)

Q: Can UF2M_R1_00001 be used as a direct replacement for US2M-TP?

A: Yes. The UF2M_R1_00001 meets all critical electrical and mechanical parameters: 1000 V reverse voltage, 2 A average rectified current, 1.7 V forward voltage at 2 A, fast recovery speed classification, and DO-214AA (SMB) surface mount package. Both parts are RoHS3 compliant with MSL 1 rating. The UF2M_R1_00001 exhibits lower reverse leakage current (1 µA vs. 5 µA) and a wider operating temperature range (-55°C to 150°C vs. -50°C to 150°C).

Q: What are the differences between ER2M and US2M-TP?

A: The ER2M and US2M-TP are parametrically equivalent for all critical specifications: 1000 V reverse voltage, 2 A average rectified current, 1.7 V forward voltage at 2 A, and DO-214AA (SMB) package. The ER2M has a faster reverse recovery time (75 ns vs. 100 ns). The ER2M does not have an MSL rating specified, whereas the US2M-TP is MSL 1. Both are RoHS3 compliant and Active status.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the DO-214AA (SMB) surface mount package with identical pin configuration and footprint. They are mechanically and electrically interchangeable at the board level.

Q: Which substitute part should be selected for high-temperature applications?

A: The UF2M_R1_00001 has the widest operating temperature range (-55°C to 150°C), making it suitable for applications requiring extended low-temperature operation. The US2M-TP and ER2M both operate to 150°C maximum junction temperature with lower temperature limits of -50°C.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. The US2M-TP, UF2M_R1_00001, and ER2M are all RoHS3 compliant.

Q: What is the significance of reverse recovery time differences?

A: The ER2M has a reverse recovery time of 75 ns compared to 100 ns for the US2M-TP and UF2M_R1_00001. Faster reverse recovery reduces switching losses and improves efficiency in high-frequency switching applications. All three parts meet the fast recovery speed classification (≤ 500 ns, > 200 mA).

Q: Are moisture sensitivity levels equivalent across all parts?

A: The US2M-TP and UF2M_R1_00001 both have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The ER2M has MSL listed as Not Applicable. For applications with strict moisture handling requirements, the US2M-TP or UF2M_R1_00001 are preferred.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design does not have manufacturer-specific requirements. All three parts share identical electrical ratings for voltage, current, and forward voltage, and use the same DO-214AA (SMB) package. Designs should verify that any manufacturer-specific certifications or approvals are not required.
