Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZX884S-B68YL is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitutes:

Electrical Parameters (Must Match Exactly):

• Voltage - Zener (Nominal): 68 V
• Tolerance: ±2.06%
• Power - Maximum: 365 mW
• Impedance (Maximum): 240 Ohms
• Current - Reverse Leakage @ Vr: 50 nA @ 47.6 V
• Voltage - Forward (Maximum) @ If: 900 mV @ 10 mA
• Operating Temperature (Junction): 150°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: SOD-882
• Supplier Device Package: DFN1006BD-2
• Mounting Type: Surface Mount

Compliance Parameters (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts identified below meet all these criteria. Differences in product status (active versus obsolete) and packaging format (Tape & Reel versus standard) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: BZX884S-B68-QYL or BZX884S-C68-QYL

Both substitute parts are functionally equivalent to the BZX884S-B68YL across all electrical and mechanical specifications. The substitutes offer the following advantages:

Product Status: Both substitute parts carry active product status, ensuring ongoing manufacturer support, continued availability, and long-term supply chain stability compared to the obsolete main part.

Compliance & Certification: Both substitutes are qualified to AEC-Q100 automotive standards and carry Automotive grade designation. This qualification provides additional assurance for applications requiring automotive-level reliability and traceability.

Regulatory Compliance: All three parts maintain identical RoHS3 compliance and REACH unaffected status, ensuring regulatory requirements are met without modification.

Packaging Availability: The substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes. The main part does not specify packaging format, making the TR format a practical advantage for production environments.

Selection Between Substitutes: BZX884S-B68-QYL and BZX884S-C68-QYL are electrically and mechanically identical. Selection between these two parts may be based on inventory availability or specific procurement requirements, as both meet all technical specifications.

Frequently Asked Questions (FAQ)

Q: Can BZX884S-B68-QYL or BZX884S-C68-QYL be used as direct replacements for BZX884S-B68YL?

A: Yes. Both substitute parts are parametrically equivalent across all electrical characteristics (voltage, tolerance, power rating, impedance, leakage current, forward voltage) and mechanical specifications (package type, mounting method, physical dimensions). Direct substitution is supported without circuit modification.

Q: What is the difference between BZX884S-B68-QYL and BZX884S-C68-QYL?

A: Both parts are electrically and mechanically identical. The difference lies in the part number designation (B68 versus C68), which reflects internal Nexperia classification. Both are active products with AEC-Q100 automotive qualification. Selection between them is based on availability or procurement preference.

Q: Why is the main part BZX884S-B68YL marked as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this specific part number. The substitute parts with active status provide equivalent functionality with ongoing manufacturer support and supply availability.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. Both BZX884S-B68-QYL and BZX884S-C68-QYL carry Automotive grade designation and AEC-Q100 qualification, meeting automotive industry reliability and traceability standards.

Q: Does the Tape & Reel packaging of the substitute parts affect compatibility?

A: No. Tape & Reel is a standard packaging format for surface mount components and does not affect electrical performance or mechanical fit. The SOD-882 package and DFN1006BD-2 supplier device package remain identical, ensuring PCB footprint compatibility.

Q: Are there any compliance or regulatory differences between the main part and substitutes?

A: No. All three parts maintain identical RoHS3 compliance, REACH unaffected status, and environmental classification. Regulatory requirements are met without modification.

Q: What inventory status should be considered when selecting between these parts?

A: BZX884S-B68-QYL has 11,171 pieces in stock, and BZX884S-C68-QYL has 10,826 pieces in stock. Both substitutes offer significantly higher availability compared to the obsolete main part (699 pieces). For new designs or long-term production, the active substitute parts are recommended.
