Frequently Asked Questions (FAQ)

Q: Can CMSH1-60M TR13 be directly replaced with B160-13-F?

A: Yes. Both parts share identical voltage ratings (60 V), current ratings (1 A), forward voltage characteristics (700 mV @ 1 A), recovery speed (Fast Recovery ≤ 500 ns), reverse leakage (500 µA @ 60 V), and operating temperature range (-65°C ~ 150°C). Both use the DO-214AC SMA surface mount package. The parts are electrically and mechanically interchangeable.

Q: What is the difference between CMSH1-60M TR13 and CMSH1-60M TR13 PBFREE?

A: CMSH1-60M TR13 PBFREE is a lead-free variant of the same part with identical electrical specifications. The primary difference is ROHS3 compliance certification on the PBFREE version. Both parts are functionally equivalent.

Q: Is B160Q-13-F suitable for non-automotive applications?

A: Yes. B160Q-13-F meets all electrical and mechanical requirements for standard rectification applications. The AEC-Q101 automotive qualification is an additional certification that does not restrict use in non-automotive circuits. It is a superset-qualified part suitable for any application requiring 60 V, 1 A Schottky rectification.

Q: What is the significance of the capacitance difference between CMSH1-60M TR13 (43 pF @ 4V, 1 MHz) and B160-13-F (110 pF @ 4V, 1 MHz)?

A: Capacitance variation is a secondary parameter that does not affect core rectification function. Both parts meet the fast recovery speed requirement (≤ 500 ns). Capacitance differences may affect high-frequency switching performance in specific circuit topologies, but both parts are qualified as functional equivalents for standard rectification applications.

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

A: No. CMSH1-60M TR13 is specified with Tape & Reel packaging. CMSH1-60M TR13 PBFREE is also Tape & Reel. B160-13-F is available in Cut Tape and Digi-Reel formats. B160Q-13-F and CDBA160-G are Tape & Reel. Packaging format selection depends on assembly process requirements and procurement volume.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts use the identical DO-214AC SMA surface mount package with the same pin configuration and footprint. PCB layout and assembly processes require no modification for part substitution.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are ROHS3 compliant and REACH unaffected. B160Q-13-F includes additional AEC-Q101 automotive qualification. All parts carry EAR99 export classification and HTSUS code 8541.10.0080.
