BAS316/ZLF Equivalent & Substitute Parts

Part Overview

The BAS316/ZLF is a general-purpose fast recovery diode rated for 100 V DC reverse voltage and 215 mA average rectified current in a surface mount SOD-323 package. Manufactured by NXP USA Inc., this component is classified as obsolete. Due to its obsolete status and limited inventory availability (1085 pcs), identifying active equivalent and substitute parts is necessary for design continuity and procurement reliability in production environments.

Substitute Part Grouping Explanation

Substitution of the BAS316/ZLF is determined by the following critical parameters:

Voltage Rating: All substitute parts maintain the 100 V DC reverse voltage specification, ensuring equivalent reverse bias capability.

Package: All substitutes use the SOD-323 surface mount package, providing identical mechanical and thermal interface compatibility.

Speed Characteristics: All substitutes maintain fast recovery performance with reverse recovery time (trr) of 4 ns and speed classification of fast recovery ≤ 500 ns for currents > 200 mA (Io).

Forward Voltage: All substitutes maintain 1.25 V maximum forward voltage at 150 mA, ensuring equivalent conduction characteristics.

Leakage Current: All substitutes maintain 500 nA maximum reverse leakage current at 80 V, providing equivalent reverse bias performance.

Capacitance: All substitutes maintain 1.5 pF capacitance at 0 V and 1 MHz, ensuring equivalent high-frequency behavior.

The substitute parts (BAS316Z, BAS316,115, BAS316,135) differ from the main part in current rating (250 mA versus 215 mA) and product status (active versus obsolete). These substitutes are parametrically equivalent and functionally interchangeable within the specified electrical envelope.

Engineering Selection Recommendations

For Obsolete Part Replacement: The BAS316/ZLF is classified as obsolete. All three substitute parts (BAS316Z, BAS316,115, BAS316,135) are active products manufactured by Nexperia USA Inc., ensuring long-term availability and supply chain continuity.

For Compliance Requirements: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental and regulatory compliance profile of the original part.

For Automotive Applications: The substitute parts BAS316Z, BAS316,115, and BAS316,135 carry automotive grade designation and AEC-Q101 qualification, providing enhanced reliability assurance for automotive and mission-critical applications.

For Current Margin: The substitute parts are rated for 250 mA average rectified current, providing a 16% current margin above the original 215 mA specification. This increased rating does not alter electrical characteristics and provides design headroom for circuit variations.

For Inventory Availability: Substitute parts maintain significantly higher inventory levels (36,788 to 240,400 pcs) compared to the original part (1,085 pcs), ensuring reliable procurement for production volumes.

Frequently Asked Questions (FAQ)

Q: Can BAS316Z, BAS316,115, and BAS316,135 be used as direct replacements for BAS316/ZLF?

A: Yes. All substitute parts maintain identical electrical parameters for voltage rating, forward voltage, reverse recovery time, leakage current, and capacitance. The SOD-323 package provides identical mechanical and thermal interface compatibility. The increased current rating (250 mA versus 215 mA) does not affect substitutability within the specified electrical envelope.

Q: What is the difference between BAS316Z, BAS316,115, and BAS316,135?

A: All three parts are parametrically identical. They differ only in packaging format: BAS316Z, BAS316,115, and BAS316,135 are supplied in Cut Tape (CT) and Digi-Reel® packaging. Selection between these three parts depends on procurement and assembly process requirements rather than electrical performance.

Q: Why do the substitute parts have a higher current rating (250 mA) than the original part (215 mA)?

A: The substitute parts represent an updated product line within the BAS16 series. The higher current rating reflects improved manufacturing processes and materials while maintaining all other electrical characteristics. This provides additional design margin without requiring circuit modifications.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. BAS316Z, BAS316,115, and BAS316,135 carry automotive grade designation and AEC-Q101 qualification, meeting automotive reliability and qualification standards. The original BAS316/ZLF does not carry automotive qualification.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the original and substitutes, have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: Are there any temperature operating differences between the original and substitute parts?

A: No. All parts maintain identical maximum junction operating temperature of 150°C.

Q: Do the substitute parts meet RoHS and REACH compliance?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original BAS316/ZLF.
