Substitute Part Grouping Explanation

Substitution between PDZ3.3B-QX and PDZ3.3B,115 is valid based on identical electrical and mechanical parameters. Both parts share the same nominal Zener voltage (3.3 V), tolerance (±2%), maximum power rating (400 mW), impedance specification (95 Ohms maximum), reverse leakage current (5 µA @ 1 V), forward voltage (1.1 V @ 100 mA), operating temperature rating (150°C), and physical package (SOD-323). Both maintain Active product status, comply with ROHS3 and REACH requirements, and carry AEC-Q101 automotive qualification.

The sole distinction between these parts is packaging format: PDZ3.3B-QX is supplied in Tape & Reel (TR) configuration, while PDZ3.3B,115 is supplied in Cut Tape (CT) & Digi-Reel® format. This difference affects procurement and handling logistics but does not alter component performance or electrical characteristics.

Engineering Selection Recommendations

Both PDZ3.3B-QX and PDZ3.3B,115 are Active products manufactured by Nexperia USA Inc. with identical electrical specifications and compliance certifications. Selection between these parts should be based on procurement requirements and assembly process compatibility.

PDZ3.3B-QX in Tape & Reel format is suitable for high-volume automated assembly operations requiring continuous reel feeding. PDZ3.3B,115 in Cut Tape & Digi-Reel® format accommodates lower-volume production runs, manual assembly processes, or applications requiring smaller quantity increments.

Both parts satisfy automotive-grade requirements through AEC-Q101 qualification and maintain full compliance with ROHS3 and REACH regulations. Moisture sensitivity level 1 (Unlimited) indicates no special storage or handling precautions are required prior to assembly.

Frequently Asked Questions (FAQ)

Q: Can PDZ3.3B,115 be used as a direct replacement for PDZ3.3B-QX in circuit design?

A: Yes. Both parts are electrically and mechanically identical. The 3.3 V Zener voltage, 400 mW power rating, impedance, leakage current, and forward voltage specifications are identical. The SOD-323 package dimensions and pin configuration are identical. Substitution is valid from a circuit performance perspective.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) supplies components on a continuous reel suitable for automated pick-and-place equipment in high-volume manufacturing. Cut Tape (CT) & Digi-Reel® supplies components in shorter tape segments or alternative reel formats, accommodating lower-volume orders or manual assembly processes. Both formats contain the same component.

Q: Are there any compliance or certification differences between these parts?

A: No. Both PDZ3.3B-QX and PDZ3.3B,115 carry identical certifications: AEC-Q101 automotive qualification, ROHS3 compliance, and REACH unaffected status. Both maintain Moisture Sensitivity Level 1 (Unlimited), requiring no special handling.

Q: Which part should be selected for automotive applications?

A: Both parts are qualified for automotive use through AEC-Q101 certification. Selection should be based on manufacturing process requirements. High-volume automotive production typically uses Tape & Reel format (PDZ3.3B-QX), while lower-volume or prototype applications may use Cut Tape & Digi-Reel® format (PDZ3.3B,115).

Q: Is the 95 Ohm impedance specification identical between both parts?

A: Yes. Both PDZ3.3B-QX and PDZ3.3B,115 specify a maximum impedance (Zzt) of 95 Ohms, ensuring identical dynamic impedance characteristics in circuit operation.
