FS2J-TP Equivalent & Substitute Parts

Part Overview

The FS2J-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-214AC (HSMA) package. This part is classified as obsolete, necessitating identification of equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while accommodating packaging and availability constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FS2J-TP is determined by the following critical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V minimum
• Current - Average Rectified (Io): 2 A minimum
• Package / Case: DO-214AC, SMA compatible
• Mounting Type: Surface Mount
• Operating Temperature Range: -50°C to 150°C minimum coverage
• RoHS Status: ROHS3 Compliant

Substitution Categories:

Direct Equivalent (Identical Electrical Performance): Parts that match all primary criteria with no performance degradation.

Functional Equivalent (Acceptable Performance Trade-offs): Parts that meet voltage and package requirements but may have reduced current rating or different recovery characteristics, suitable only where application current requirements are lower than the part's rating.

Engineering Selection Recommendations

FS2J-LTP (Recommended Primary Substitute)

The FS2J-LTP is the direct equivalent substitute for the FS2J-TP. Both parts are manufactured by Micro Commercial Co and share identical electrical specifications: 600 V reverse voltage, 2 A average rectified current, 250 ns reverse recovery time, and 50 pF capacitance. The FS2J-LTP maintains the same operating temperature range (-50°C to 150°C) and package configuration (DO-214AC, SMA). The primary distinction is product status: FS2J-LTP is active, whereas FS2J-TP is obsolete. Both parts are ROHS3 compliant. The FS2J-LTP is supplied in Tape & Reel packaging, suitable for automated assembly processes. This part is the appropriate choice for direct replacement in all applications previously using the FS2J-TP.

NRVA4005T3G (Conditional Functional Equivalent)

The NRVA4005T3G, manufactured by onsemi, is a functional equivalent suitable only for applications where the circuit current requirement does not exceed 1 A. This part meets the 600 V reverse voltage requirement and uses the same DO-214AC, SMA package. However, the NRVA4005T3G has a reduced average rectified current rating of 1 A compared to the FS2J-TP's 2 A specification. The reverse leakage current is higher at 10 µA versus 5 µA. The NRVA4005T3G is classified as "Not For New Designs" and carries AEC-Q101 automotive qualification. This part is suitable only for legacy applications or where automotive-grade qualification is required and circuit current demands are confirmed below 1 A.

Frequently Asked Questions (FAQ)

Q: Can the FS2J-LTP be used as a direct replacement for the FS2J-TP?

A: Yes. The FS2J-LTP is a direct equivalent. Both parts have identical electrical specifications: 600 V reverse voltage, 2 A average rectified current, 250 ns reverse recovery time, and identical package configuration. The FS2J-LTP is the active production alternative to the obsolete FS2J-TP.

Q: What is the primary difference between FS2J-TP and FS2J-LTP?

A: The primary difference is product status and packaging format. The FS2J-TP is obsolete and supplied in bulk packaging, while the FS2J-LTP is active and supplied in Tape & Reel format. Electrical performance is identical.

Q: Can the NRVA4005T3G replace the FS2J-TP in all applications?

A: No. The NRVA4005T3G has a reduced current rating of 1 A versus the FS2J-TP's 2 A specification. This part is suitable only for applications where the circuit current requirement does not exceed 1 A. Exceeding this current rating will result in device failure.

Q: Are all substitute parts RoHS compliant?

A: Yes. Both the FS2J-LTP and NRVA4005T3G are ROHS3 compliant, matching the compliance status of the FS2J-TP.

Q: What is the operating temperature range for substitute parts?

A: The FS2J-LTP operates from -50°C to 150°C junction temperature, identical to the FS2J-TP. The NRVA4005T3G operates from -55°C to 150°C, providing a slightly extended lower temperature range.

Q: Does the NRVA4005T3G have automotive qualification?

A: Yes. The NRVA4005T3G carries AEC-Q101 automotive qualification and is suitable for automotive applications. However, it is classified as "Not For New Designs," limiting its use to legacy or maintenance applications.

Q: What packaging formats are available for substitute parts?

A: The FS2J-LTP is supplied in Tape & Reel (TR) format, suitable for automated assembly. The NRVA4005T3G is also supplied in Tape & Reel format. Both use the DO-214AC, SMA surface mount package.

Q: How do reverse leakage currents compare between parts?

A: The FS2J-TP and FS2J-LTP both have 5 µA reverse leakage current at 600 V. The NRVA4005T3G has higher reverse leakage at 10 µA at 600 V, which may be significant in high-impedance or precision applications.
