Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly based on matching the critical electrical, mechanical, and compliance parameters described in the reference part: Zener voltage (Vz), tolerance, maximum power dissipation, impedance, reverse leakage, forward voltage, operating temperature, automotive grade, qualification level (AEC-Q101), mounting type, package format, RoHS/REACH status, moisture sensitivity, and regulatory codes. Substitute models are selected only if all these parameters are equivalent to those of the PDZ2.4B-QF Zener diode.

Parameter Comparison

Engineering Selection Recommendations

The PDZ2.4B-QF is designated as Obsolete. Both PDZ2.4B,115 and PDZ2.4B-QX are listed as Active and share ROHS3 Compliant and REACH Unaffected status. PDZ2.4B-QX duplicates the automotive grade and AEC-Q101 qualification parameters of the main part, while PDZ2.4B,115 does not specify these fields. When complete matching of automotive and qualification criteria is required, select PDZ2.4B-QX. If these factors are not mandatory, both substitutes meet all other specified parameters for direct replacement.

Frequently Asked Questions (FAQ)

Q1: Which substitute part is most compatible with the PDZ2.4B-QF for automotive applications?
A1: PDZ2.4B-QX matches the automotive grade and AEC-Q101 qualification of the PDZ2.4B-QF and is therefore most compatible for automotive use.

Q2: Are both substitute parts electrically equivalent to the original PDZ2.4B-QF Zener diode?
A2: Both PDZ2.4B,115 and PDZ2.4B-QX provide full equivalence in electrical parameters including Zener voltage, tolerance, max power, impedance, reverse leakage, forward voltage, and operating temperature.

Q3: Is there any difference in package type among the substitute parts?
A3: All models use the SC-76, SOD-323 package with SOD-323 supplier device package, ensuring mechanical compatibility.

Q4: Do substitute parts comply with the same RoHS and REACH standards?
A4: Both substitute parts are ROHS3 Compliant and REACH Unaffected, identical to the PDZ2.4B-QF.

Q5: What inventory status applies to substitute selection?
A5: PDZ2.4B-QX and PDZ2.4B,115 are listed as Active, while PDZ2.4B-QF is Obsolete. Selection should be based on availability and status for ongoing production requirements.
