Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the BYG10KHE3_A/I?

A: Substitution is determined by equivalence across electrical parameters (reverse voltage, forward current, forward voltage, reverse recovery time, reverse leakage current), technology type (avalanche), package configuration (DO-214AC, SMA), mounting type (surface mount), and operating temperature range (-55°C to 150°C). All substitute parts must maintain these specifications identically.

Q: Are the substitute parts pin-compatible with the BYG10KHE3_A/I?

A: Yes. All substitute parts use the identical DO-214AC (SMA) package configuration and surface mount mounting type, ensuring mechanical and electrical pin compatibility without PCB redesign.

Q: What is the difference between BYG10K-E3/TR3 and BYG10KHE3_A/H?

A: Both parts are electrically and mechanically equivalent to the BYG10KHE3_A/I. The BYG10KHE3_A/H carries automotive-grade qualification (AEC-Q101) matching the main part. The BYG10K-E3/TR3 does not list automotive qualification in the provided specifications. Selection depends on application requirements for automotive certification.

Q: Can these parts be used interchangeably in automotive applications?

A: The BYG10KHE3_A/H is specified with automotive-grade qualification (AEC-Q101) and is suitable for automotive applications. The BYG10K-E3/TR3 does not list automotive qualification in the provided data. For automotive applications, BYG10KHE3_A/H is the appropriate substitute.

Q: What is the significance of the packaging designation (TR)?

A: The TR designation indicates Tape & Reel packaging format, which is standard for surface mount components in high-volume manufacturing. All listed parts use this packaging format, ensuring compatibility with automated assembly processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (BYG10K-E3/TR3 and BYG10KHE3_A/H) are ROHS3 compliant and REACH unaffected, matching the compliance status of the main part BYG10KHE3_A/I.
