Engineering Selection Recommendations

SR206 (Taiwan Semiconductor Corporation) is a parametric equivalent offering identical electrical specifications and operating temperature range. This part is suitable for direct substitution in applications currently using SR206H. The primary distinction is packaging format: SR206 is supplied in Cut Tape (CT) format versus SR206H in Tape & Reel (TR) format. Both parts maintain ROHS3 compliance and active product status.

SB260-E3/73 (Vishay General Semiconductor - Diodes Division) is a parametric equivalent with matching voltage and current ratings. Forward voltage is 20 mV lower (680 mV @ 2 A versus 700 mV @ 2 A), resulting in reduced power dissipation. Operating temperature range extends to -65°C minimum, providing enhanced low-temperature performance. This part is suitable for substitution where improved thermal characteristics are beneficial. ROHS3 compliance and active product status are maintained.

STPS3L60Q (STMicroelectronics) is a similar part with higher current rating (3 A versus 2 A) and lower reverse leakage current (60 µA @ 60 V versus 500 µA @ 60 V). Forward voltage is 620 mV @ 3 A. This part is suitable for applications requiring higher current capacity or lower leakage characteristics. ROHS3 compliance and active product status are maintained. Operating temperature maximum is specified as 150°C without minimum temperature range provided.

SB260_R2_00001 (Panjit International Inc.) is a parametric equivalent with matching voltage, current, and forward voltage specifications. Reverse leakage current is 100 µA @ 60 V, lower than SR206H. Operating temperature range matches SR206H at -55°C ~ 150°C. This part is suitable for direct substitution. ROHS3 compliance and active product status are maintained.

All substitute parts are active-status components compliant with ROHS3 and REACH regulations, suitable for through-hole assembly in DO-204AC (DO-15) axial package configurations.

Frequently Asked Questions (FAQ)

Q: Can SR206 replace SR206H in a circuit design?

A: Yes. SR206 is a parametric equivalent with identical electrical specifications (60 V, 2 A, 700 mV @ 2 A) and operating temperature range (-55°C ~ 150°C). The difference is packaging format: SR206 is supplied in Cut Tape (CT) while SR206H is supplied in Tape & Reel (TR). Both are through-hole DO-204AC (DO-15) axial components suitable for the same circuit applications.

Q: What is the difference between SB260-E3/73 and SR206H?

A: SB260-E3/73 shares the same voltage (60 V) and current (2 A) ratings as SR206H. Forward voltage is 20 mV lower (680 mV @ 2 A), reducing power dissipation. Operating temperature minimum extends to -65°C versus -55°C for SR206H. Both parts use identical DO-204AC (DO-15) axial through-hole packaging. SB260-E3/73 is suitable for substitution where lower forward voltage or extended low-temperature operation is required.

Q: When should STPS3L60Q be selected over SR206H?

A: STPS3L60Q is suitable when the application requires higher current capacity (3 A versus 2 A) or lower reverse leakage current (60 µA @ 60 V versus 500 µA @ 60 V). Both parts maintain 60 V reverse voltage rating and fast recovery speed. STPS3L60Q uses the same DO-204AC (DO-15) axial through-hole package. Selection depends on circuit current requirements and leakage specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SR206, SB260-E3/73, STPS3L60Q, and SB260_R2_00001 are all ROHS3 compliant and REACH unaffected, matching the compliance status of SR206H.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for lower-volume or mixed-component assembly. Both formats contain identical components in DO-204AC (DO-15) axial through-hole packages. Selection depends on assembly process requirements.

Q: Can SB260_R2_00001 be used as a direct replacement for SR206H?

A: Yes. SB260_R2_00001 is a parametric equivalent with matching specifications: 60 V reverse voltage, 2 A current rating, 700 mV @ 2 A forward voltage, and -55°C ~ 150°C operating temperature range. Both use DO-204AC (DO-15) axial through-hole packaging. Reverse leakage current is lower (100 µA @ 60 V versus 500 µA @ 60 V), which is beneficial for circuit performance.

Q: Do all substitute parts support automotive applications?

A: SR206H is qualified to AEC-Q101 automotive standards. Substitute parts SR206, SB260-E3/73, STPS3L60Q, and SB260_R2_00001 are active-status components with ROHS3 compliance. Automotive qualification status for substitute parts is not specified in the provided parameters. Verification of automotive qualification requirements should be performed based on specific application standards.
