SF16-TP Equivalent & Substitute Parts

Part Overview

The SF16-TP is a general-purpose rectifier diode rated for 400 V DC reverse voltage and 1 A average rectified current in a DO-41 through-hole package. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary for ongoing design support, production continuity, and long-term component availability.

Substitute Part Grouping Explanation

Substitute parts for the SF16-TP are selected based on electrical and mechanical compatibility within the following criteria:

Primary Substitution Criteria:

Current - Average Rectified (Io): 1 A minimum
Mounting Type: Through Hole
Package / Case: DO-204AL, DO-41, or Axial configuration
RoHS Compliance: ROHS3 Compliant

Secondary Compatibility Factors:

Voltage - Forward (Vf) (Max) @ If: Within 1.3 V @ 1 A specification

Engineering Selection Recommendations

SF16G-TP (Micro Commercial Co)

SF16G-TP is the primary substitute for SF16-TP. Both parts share identical electrical specifications including 400 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage drop, and 35 ns reverse recovery time. SF16G-TP is an active product with extended operating temperature range (-55°C ~ 150°C versus -55°C ~ 125°C) and improved capacitance characteristics (10pF versus 25pF @ 4V, 1MHz). ROHS3 compliance and MSL 1 rating are maintained. This substitute provides direct functional equivalence with enhanced performance margins.

BYD13GGPHE3/54 (Vishay General Semiconductor - Diodes Division)

BYD13GGPHE3/54 meets all primary electrical and mechanical requirements with 400 V reverse voltage and 1 A average rectified current in DO-41 package. This part operates at standard recovery speed (>500ns) compared to the fast recovery specification of SF16-TP. Operating temperature range extends to -65°C ~ 175°C. ROHS3 compliance and MSL 1 rating are confirmed. This substitute is suitable for applications where standard recovery speed is acceptable and extended temperature operation is beneficial.

MUR140-T (Diodes Incorporated)

MUR140-T provides cross-manufacturer substitution with matching 400 V reverse voltage and 1 A average rectified current specifications. Forward voltage is 1.25 V @ 1 A, slightly lower than SF16-TP. Reverse recovery time is 75 ns, longer than SF16-TP's 35 ns. Operating temperature range extends to -65°C ~ 175°C. ROHS3 compliance and MSL 1 rating are confirmed. This substitute is suitable for applications where the extended temperature range and lower forward voltage drop are advantageous.

All three substitutes maintain ROHS3 compliance, MSL 1 rating, and through-hole DO-41 package compatibility with the obsolete SF16-TP.

Frequently Asked Questions (FAQ)

Q: Can SF16G-TP directly replace SF16-TP without circuit modification?

A: Yes. SF16G-TP is electrically and mechanically equivalent to SF16-TP. Both parts share identical voltage ratings (400 V), current ratings (1 A), forward voltage drop (1.3 V @ 1 A), and reverse recovery time (35 ns). Package configuration and mounting type are identical. No circuit modification is required.

Q: What is the primary difference between SF16G-TP and BYD13GGPHE3/54?

A: The primary difference is speed classification. SF16G-TP operates at fast recovery speed (≤ 500ns), while BYD13GGPHE3/54 operates at standard recovery speed (>500ns). Both meet the 400 V / 1 A electrical requirements. Selection depends on circuit switching frequency requirements. Fast recovery diodes are preferred in high-frequency switching applications.

Q: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts (SF16G-TP, BYD13GGPHE3/54, MUR140-T) are available in DO-204AL, DO-41, and axial package configurations. Physical dimensions and pin spacing are compatible with the original SF16-TP footprint.

Q: What is the impact of different reverse recovery times on circuit performance?

A: Reverse recovery time (trr) affects switching speed and switching losses. SF16-TP and SF16G-TP have 35 ns trr, MUR140-T has 75 ns trr. Shorter recovery times reduce switching losses and enable higher switching frequencies. Selection depends on circuit operating frequency and efficiency requirements.

Q: Do all substitutes meet RoHS compliance requirements?

A: Yes. All substitute parts (SF16G-TP, BYD13GGPHE3/54, MUR140-T) are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level). All parts are suitable for applications requiring RoHS compliance.

Q: What is the significance of operating temperature range differences?

A: SF16-TP operates from -55°C to 125°C. SF16G-TP extends to 150°C, while BYD13GGPHE3/54 and MUR140-T extend to 175°C. Extended temperature ranges provide design margin for high-temperature environments and thermal stress conditions. Selection depends on application thermal requirements.

Q: Can MUR140-T be used in place of SF16-TP in all applications?

A: MUR140-T meets all primary electrical and mechanical requirements (400 V, 1 A, DO-41 package). The lower forward voltage drop (1.25 V versus 1.3 V) and longer reverse recovery time (75 ns versus 35 ns) are acceptable in most applications. Verify circuit switching frequency and thermal design compatibility before substitution.
