US2J-TP Equivalent & Substitute Parts

Part Overview

The US2J-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 600 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AA (SMB) package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identification of equivalent and substitute parts is necessary to support existing designs, legacy system maintenance, and production continuity where the original part is no longer available or economically viable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the US2J-TP is determined by matching the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V minimum
• Current - Average Rectified (Io): 2 A minimum
• Package / Case: DO-214AA (SMB) surface mount
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

Secondary Compatibility Factors:

• Reverse Recovery Time (trr): Fast recovery characteristics (≤ 500 ns)
• Voltage - Forward (Vf): Nominal 1.7 V @ 2 A or lower
• Current - Reverse Leakage: 5 µA @ 600 V or lower
• Operating Temperature Range: Minimum -50°C to +150°C

Substitute parts are classified into two categories:

Upgrade Equivalents: Parts with identical or superior electrical ratings and active product status, suitable for direct replacement in new production or redesign scenarios.

Parametric Equivalents: Parts meeting all critical electrical and mechanical requirements with active product status and enhanced availability.

Engineering Selection Recommendations

HS2J (Upgrade Equivalent - Recommended Primary Substitute)

The HS2J manufactured by Taiwan Semiconductor Corporation is the optimal substitute for the US2J-TP. It maintains identical electrical ratings (600 V, 2 A) and package configuration (DO-214AA SMB). The HS2J offers improved reverse recovery time (75 ns versus 100 ns), wider operating temperature range (-55°C to +150°C), and active product status. This part is suitable for direct replacement in both legacy support and new design implementations. Inventory availability is 6,400 pieces.

ER2J (Parametric Equivalent - Secondary Substitute)

The ER2J from Diotec Semiconductor provides full parametric equivalence to the US2J-TP with identical voltage (600 V) and current (2 A) ratings. The ER2J features improved reverse recovery time (75 ns) and is actively manufactured. This part is suitable for applications where the primary substitute is unavailable. Inventory availability is 41,250 pieces, providing superior supply continuity.

MURS360SHE3_A/H (Similar Substitute - Current-Limited Applications)

The MURS360SHE3_A/H from Vishay General Semiconductor is a similar substitute suitable only for applications where the average rectified current requirement does not exceed 1.5 A. This part maintains the 600 V reverse voltage rating and DO-214AA SMB package. The MURS360SHE3_A/H includes automotive-grade qualification (AEC-Q101) and an extended operating temperature range (-65°C to +175°C). This part is appropriate for current-limited designs or automotive applications requiring enhanced temperature performance. Inventory availability is 908 pieces.

Frequently Asked Questions (FAQ)

Q: Can the HS2J directly replace the US2J-TP without circuit modification?

A: Yes. The HS2J maintains identical voltage (600 V) and current (2 A) ratings, forward voltage characteristics (1.7 V @ 2 A), and package configuration (DO-214AA SMB). Direct substitution is supported without circuit redesign.

Q: What is the difference between the ER2J and HS2J substitutes?

A: Both parts meet identical electrical specifications (600 V, 2 A, 1.7 V forward voltage). The primary differences are manufacturer (Diotec versus Taiwan Semiconductor), reverse recovery time (both 75 ns), and inventory availability (ER2J: 41,250 pieces; HS2J: 6,400 pieces). Selection between these parts is based on supply chain preference and availability.

Q: Why is the MURS360SHE3_A/H listed as a similar substitute rather than a direct equivalent?

A: The MURS360SHE3_A/H has a reduced average rectified current rating of 1.5 A compared to the US2J-TP's 2 A rating. This part is suitable only for applications where the circuit current requirement does not exceed 1.5 A. For applications requiring the full 2 A rating, the HS2J or ER2J must be used.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The HS2J, ER2J, and MURS360SHE3_A/H are all ROHS3 compliant, matching the compliance status of the original US2J-TP.

Q: What is the significance of the US2J-TP being marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. Existing inventory (4,228 pieces) supports legacy system maintenance only. For new designs, the HS2J or ER2J should be selected as active, production-supported alternatives.

Q: Do the substitute parts maintain the same package footprint?

A: Yes. All substitute parts (HS2J, ER2J, MURS360SHE3_A/H) use the DO-214AA (SMB) surface mount package, ensuring mechanical and PCB layout compatibility with the original US2J-TP.

Q: What is the operating temperature range difference between substitutes?

A: The US2J-TP operates from -50°C to +150°C. The HS2J extends the lower limit to -55°C. The ER2J maintains the original range (-50°C to +150°C). The MURS360SHE3_A/H provides the widest range (-65°C to +175°C), suitable for automotive and extended-temperature applications.
