Substitute Part Grouping Explanation

Substitution of the PLZ24C-G3/H is determined by the following critical parameters:

Electrical Parameters (Must Match):

Voltage - Zener (Nom): 24 V
Power - Max: 500 mW
Impedance (Max): 35 Ohms
Current - Reverse Leakage @ Vr: 200 nA @ 19 V
Voltage - Forward (Vf) (Max) @ If: 900 mV @ 10 mA
Operating Temperature: 150°C

Mechanical Parameters (Must Match):

Package / Case: DO-219AC
Mounting Type: Surface Mount
Supplier Device Package: DO-219AC (microSMF)

Tolerance Consideration: The PLZ24C-G3/H specifies ±3% voltage tolerance. Parts with ±2.5% tolerance (PLZ24A-G3/H, PLZ24A-HG3_A/H) represent tighter tolerance variants and are electrically compatible substitutes. Parts with ±3% tolerance (PLZ24D-G3/H, PLZ24C-HG3_A/H, PLZ24D-HG3_A/H) maintain identical tolerance specifications.

Automotive Qualification: Certain substitute parts carry AEC-Q101 automotive qualification (PLZ24A-HG3_A/H, PLZ24C-HG3_A/H, PLZ24D-HG3_A/H). These are suitable for applications requiring automotive-grade components.

Engineering Selection Recommendations

For Standard Applications (Non-Automotive): PLZ24D-G3/H and PLZ24A-G3/H are direct substitutes with identical electrical specifications and standard product grade. PLZ24A-G3/H offers tighter ±2.5% tolerance if voltage regulation precision is critical. PLZ24D-G3/H maintains ±3% tolerance matching the primary part.

For Automotive Applications: PLZ24A-HG3_A/H, PLZ24C-HG3_A/H, and PLZ24D-HG3_A/H carry AEC-Q101 automotive qualification and are suitable for automotive circuit designs. PLZ24A-HG3_A/H provides the highest inventory availability (15,266 pcs) with tighter ±2.5% tolerance. PLZ24C-HG3_A/H and PLZ24D-HG3_A/H maintain ±3% tolerance with AEC-Q101 qualification.

Compliance and Regulatory: All substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status. All parts are classified as Active product status.

Frequently Asked Questions (FAQ)

Q: Can PLZ24A-G3/H replace PLZ24C-G3/H directly? A: Yes. PLZ24A-G3/H is electrically equivalent with identical nominal voltage (24 V), power rating (500 mW), impedance (35 Ω), and all other electrical parameters. The difference is tighter voltage tolerance (±2.5% versus ±3%), which provides improved voltage regulation performance.

Q: What is the difference between standard and automotive-grade variants? A: Automotive-grade variants (PLZ24A-HG3_A/H, PLZ24C-HG3_A/H, PLZ24D-HG3_A/H) carry AEC-Q101 qualification, indicating compliance with automotive reliability and testing standards. Standard variants (PLZ24C-G3/H, PLZ24A-G3/H, PLZ24D-G3/H) do not carry this qualification. Use automotive-grade parts for automotive applications.

Q: Are all substitute parts in the same DO-219AC package? A: Yes. All listed substitute parts use the DO-219AC (microSMF) surface mount package with identical mechanical dimensions and land pattern compatibility.

Q: Which substitute has the best inventory availability? A: PLZ24A-HG3_A/H has the highest inventory with 15,266 pieces in stock. This part combines automotive-grade qualification with tighter ±2.5% tolerance.

Q: Can I use a ±2.5% tolerance part where ±3% is specified? A: Yes. Tighter tolerance (±2.5%) is a more stringent specification and is compatible with applications designed for ±3% tolerance. The part will perform within the original specification range.

Q: Are all parts ROHS3 compliant? A: Yes. All listed parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.
