SF16M-TP Equivalent & Substitute Parts

Part Overview

The SF16M-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 400 V DC reverse voltage and 1 A average rectified current in a surface mount DO-214AC (HSMA) package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical performance within the specified voltage, current, and thermal operating ranges while accommodating the surface mount package format.

Substitute Part Grouping Explanation

Substitute parts for the SF16M-TP are qualified based on the following electrical and mechanical parameters:

Primary Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 1 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 5 µA @ 400 V
• Mounting Type: Surface Mount
• Package / Case: DO-214AC, SMA
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Secondary Compatibility Parameters:

• Reverse Recovery Time (trr): ≤ 50 ns
• Operating Temperature - Junction: Minimum -55°C, Maximum ≥ 125°C
• Forward Voltage (Vf) @ 1 A: ≤ 1.3 V

Substitute parts ES1G-LTP (Micro Commercial Co) and ES1G (Good-Ark Semiconductor) satisfy all primary matching criteria and maintain electrical performance within acceptable ranges for direct substitution in applications designed for the SF16M-TP.

Engineering Selection Recommendations

ES1G-LTP (Micro Commercial Co) - Primary Substitute

The ES1G-LTP is an active product from the original manufacturer, Micro Commercial Co, and represents the direct successor to the obsolete SF16M-TP. This part maintains identical electrical specifications for voltage, current, and reverse leakage parameters. The ES1G-LTP offers improved reverse recovery time (35 ns versus 50 ns), extended maximum junction temperature rating (-65°C to 175°C versus -65°C to 150°C), and ROHS3 compliance. The part is available in high inventory quantities with Cut Tape and Digi-Reel packaging options, supporting both prototype and production-volume requirements.

ES1G (Good-Ark Semiconductor) - Secondary Substitute

The ES1G from Good-Ark Semiconductor meets all primary electrical and mechanical matching criteria. This part maintains the 400 V / 1 A rating, fast recovery speed classification, and identical reverse leakage specification. The ES1G provides improved reverse recovery time (35 ns) and ROHS3 compliance. The operating temperature range (-55°C to 125°C) is narrower than the SF16M-TP but remains suitable for standard industrial and consumer applications. Exceptionally high inventory availability (415,300 pieces) supports cost-effective procurement for high-volume production.

Selection Basis:

Both substitute parts are active products with ROHS3 compliance and MSL 1 rating, eliminating obsolescence risk. ES1G-LTP is recommended for applications requiring the extended upper temperature rating of the original SF16M-TP. ES1G is recommended for cost-sensitive applications where the standard temperature range is sufficient.

Frequently Asked Questions (FAQ)

Q: Can ES1G-LTP and ES1G be used interchangeably with SF16M-TP?

A: Both parts satisfy the core electrical specifications (400 V, 1 A, fast recovery, 5 µA reverse leakage) and package requirements (DO-214AC, SMA, surface mount). Interchangeability depends on the application's operating temperature range. For applications operating within -55°C to 125°C, both parts are suitable. For applications requiring operation above 125°C, ES1G-LTP is required due to its 175°C maximum junction temperature rating.

Q: What is the difference between the DO-214AC (HSMA) package of SF16M-TP and the DO-214AC (SMA) packages of the substitutes?

A: Both HSMA and SMA designations refer to the DO-214AC surface mount package format. The physical dimensions and PCB footprint are identical. The designations reflect supplier-specific nomenclature. All three parts are compatible with the same PCB layout and assembly process.

Q: Are there any performance differences in reverse recovery time?

A: The SF16M-TP specifies 50 ns reverse recovery time, while both ES1G-LTP and ES1G specify 35 ns. The faster recovery time of the substitute parts represents improved performance and does not create compatibility issues. Applications designed for 50 ns recovery will operate correctly with 35 ns parts.

Q: What is the significance of the capacitance differences listed in the parameter comparison?

A: Capacitance values (SF16M-TP: 10 pF, ES1G-LTP: 15 pF, ES1G: 8 pF) are measured at identical conditions (4 V, 1 MHz). These minor variations fall within normal manufacturing tolerances for this diode category and do not affect circuit functionality in standard rectification applications.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both ES1G-LTP and ES1G are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the compliance profile of the SF16M-TP.

Q: Which substitute part should be selected for new design work?

A: ES1G-LTP is the recommended choice for new designs, as it is manufactured by the original supplier (Micro Commercial Co) and offers the extended temperature range of the original part. ES1G is suitable for cost-optimized designs where the standard temperature range (-55°C to 125°C) meets application requirements.
