SF24-TP Equivalent & Substitute Parts

Part Overview

The SF24-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 200 V DC reverse voltage and 2 A average rectified current in a DO-15 through-hole package. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement. The SF24-TP features fast recovery characteristics with a reverse recovery time of 35 ns, making it suitable for standard rectification applications requiring moderate switching speeds.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SF24-TP is determined by electrical and mechanical parameter equivalence. The primary substitute identified is the SF24G-TP, which maintains identical electrical specifications across all critical parameters: 200 V reverse voltage rating, 2 A average rectified current, 950 mV forward voltage drop at 2 A, 35 ns reverse recovery time, and 5 µA reverse leakage current at 200 V. Both parts utilize the DO-15 through-hole package and are RoHS3 compliant.

The key differentiator between SF24-TP and SF24G-TP is product status and packaging format. The SF24-TP is obsolete, while SF24G-TP is active. The SF24G-TP is supplied in Cut Tape (CT) packaging, whereas the SF24-TP original packaging is not specified. Both parts share the same base product number (SF24) and are manufactured by Micro Commercial Co.

Substitution eligibility is based on the following parameters:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 2 A
• Reverse Recovery Time (trr): 35 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 200 V
• Package / Case: DO-204AC, DO-15, Axial
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

Engineering Selection Recommendations

The SF24G-TP is the direct equivalent substitute for the SF24-TP. Both parts are manufactured by Micro Commercial Co and share identical electrical and mechanical specifications. The SF24G-TP is the preferred selection because it maintains active product status, ensuring continued availability and manufacturing support.

The SF24G-TP provides an extended operating temperature range (-65°C to 150°C) compared to the SF24-TP (-55°C to 125°C), offering greater thermal margin in applications operating at temperature extremes. Both parts are RoHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), indicating no special handling requirements during storage or assembly.

The SF24G-TP is supplied in Cut Tape (CT) packaging format, which is standard for active production components. This packaging format is compatible with automated assembly processes and provides efficient component handling for manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can SF24G-TP be used as a direct replacement for SF24-TP in existing designs?

A: Yes. The SF24G-TP is electrically and mechanically equivalent to the SF24-TP. All critical parameters including reverse voltage rating (200 V), average rectified current (2 A), forward voltage drop (950 mV @ 2 A), reverse recovery time (35 ns), and package type (DO-15 through-hole) are identical. The SF24G-TP is the active equivalent of the obsolete SF24-TP.

Q: What is the difference between SF24-TP and SF24G-TP?

A: The primary differences are product status and packaging format. The SF24-TP is obsolete, while SF24G-TP is active. The SF24G-TP is supplied in Cut Tape (CT) packaging. The SF24G-TP also provides an extended operating temperature range (-65°C to 150°C versus -55°C to 125°C for the SF24-TP).

Q: Are there any thermal performance differences between these parts?

A: Both parts have identical thermal characteristics at their specified operating ranges. The SF24G-TP supports an extended junction temperature range, providing additional margin for high-temperature applications. At the SF24-TP's original operating range (-55°C to 125°C), both parts perform identically.

Q: Is the DO-15 package compatible with existing PCB layouts designed for SF24-TP?

A: Yes. Both SF24-TP and SF24G-TP use the DO-15 axial through-hole package. The physical dimensions, lead spacing, and mounting characteristics are identical, ensuring direct compatibility with existing PCB designs without layout modifications.

Q: What is the RoHS compliance status of SF24G-TP?

A: The SF24G-TP is RoHS3 compliant, matching the compliance status of the SF24-TP. Both parts meet current environmental and hazardous substance restrictions.

Q: Are there any supply chain advantages to using SF24G-TP?

A: Yes. The SF24G-TP is an active product with higher inventory availability (4809 pieces in stock versus 830 pieces for the obsolete SF24-TP). Active product status ensures continued manufacturing support and predictable long-term availability.
