BZX884S-C27YL Equivalent & Substitute Parts

Part Overview

The BZX884S-C27YL is a 27 V Zener diode manufactured by Nexperia USA Inc., rated for 365 mW maximum power dissipation in a surface mount SOD-882 package. This component is classified as obsolete, indicating discontinuation from active production. The part operates at a maximum junction temperature of 150°C and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Due to its obsolete status, direct replacement with active production equivalents is necessary for new designs and ongoing procurement. Substitute parts maintain identical electrical specifications and mechanical compatibility while offering improved tolerance characteristics and active product status.

Frequently Asked Questions (FAQ)

Q: Can BZX884S-C27-QYL and BZX884S-B27-QYL be used interchangeably with BZX884S-C27YL?

A: Yes. Both substitute parts maintain identical electrical parameters (27 V nominal zener voltage, 365 mW power rating, 80 Ohms maximum impedance) and mechanical compatibility (SOD-882 package, DFN1006BD-2 supplier package). The substitutes are pin-compatible and functionally equivalent for circuit applications.

Q: What is the primary difference between the main part and the substitutes?

A: The BZX884S-C27YL is obsolete with ±7.04% tolerance, while BZX884S-C27-QYL and BZX884S-B27-QYL are active production parts with improved ±1.85% tolerance and automotive-grade AEC-Q100 qualification. All other electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: The main part BZX884S-C27YL does not specify packaging format. The substitute parts BZX884S-C27-QYL and BZX884S-B27-QYL are supplied in Tape & Reel (TR) format. All three parts use the same SOD-882 package and DFN1006BD-2 supplier device package.
