Selection among these parts is based on inventory availability and supply chain considerations rather than technical performance differences.

PDZ13B-QF is the primary part number with 982 units in stock.

PDZ13B,115 is a parametric equivalent with 47,787 units in stock, providing superior availability for high-volume applications.

PDZ13B,135 is a parametric equivalent with 6,200 units in stock, suitable for standard production requirements.

All three parts carry AEC-Q101 automotive qualification, ROHS3 compliance, and REACH unaffected status. No design changes, board layout modifications, or thermal management adjustments are required when substituting between these part numbers. Direct 1:1 replacement is supported at the component level and assembly level.

Frequently Asked Questions (FAQ)

Q: Can PDZ13B,115 be used as a direct replacement for PDZ13B-QF?

A: Yes. PDZ13B,115 is a parametric equivalent with identical electrical characteristics (13 V nominal, ±2% tolerance, 400 mW maximum power) and mechanical specifications (SOD-323 package, surface mount). No circuit redesign or board modification is required.

Q: Are there differences in automotive qualification between these part numbers?

A: No. All three part numbers carry AEC-Q101 automotive qualification. They are functionally equivalent for automotive applications.

Q: What is the difference between PDZ13B-QF, PDZ13B,115, and PDZ13B,135?

A: These part numbers are parametric equivalents with identical electrical and mechanical specifications. Differences exist only in packaging designation and inventory availability. All three are manufactured by Nexperia USA Inc. and share the same base product number PDZ13.

Q: Can these parts be used interchangeably on the same printed circuit board?

A: Yes. All three parts use the SC-76, SOD-323 package with surface mount technology. PCB footprints, solder pad layouts, and assembly processes are identical. No board redesign is necessary.

Q: Are there any compliance or regulatory differences?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1, Unlimited). Regulatory and environmental compliance is equivalent across all part numbers.

Q: Which part number should be selected for new designs?

A: Selection is based on supply chain and inventory strategy. PDZ13B,115 offers the highest inventory availability (47,787 units). PDZ13B-QF and PDZ13B,135 are alternative sources. All three are active products suitable for production use.

Q: Is thermal management different between these parts?

A: No. All three parts have identical maximum operating junction temperature (150°C) and power dissipation rating (400 mW). Thermal design considerations are equivalent.
