BAW156/ZLR Equivalent & Substitute Parts Reference

Part Overview

The BAW156/ZLR is a general-purpose diode array manufactured by NXP USA Inc., configured as a 1 Pair Common Anode device rated for 75V DC reverse voltage and 160mA average rectified current per diode. The device is packaged in SOT-23-3 (TO-236-3, SC-59) surface mount configuration and is classified as obsolete product status. Due to its obsolete classification, identifying active equivalent and substitute parts is necessary for ongoing design support, production continuity, and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAW156/ZLR is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Diode Configuration: 1 Pair Common Anode
• Voltage - DC Reverse (Vr) (Max): 75 V
• Current - Average Rectified (Io) (per Diode): 160mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 150 mA
• Reverse Recovery Time (trr): 3 µs
• Current - Reverse Leakage @ Vr: 5 nA @ 75 V
• Operating Temperature - Junction (Max): 150°C

Mechanical Parameters (Must Match):

• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount

Compliance Parameters:

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

The identified substitute parts BAW156,215 and BAW156VL meet all electrical and mechanical equivalence criteria. Both are manufactured by Nexperia USA Inc. and maintain identical parametric specifications to the BAW156/ZLR. The primary distinction between substitutes is product status and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

For Active Production and New Designs:

Both BAW156,215 and BAW156VL are suitable direct substitutes for the obsolete BAW156/ZLR. Selection between the two active alternatives is based on the following criteria:

BAW156,215 Selection:

• Active product status with established supply chain
• ROHS3 compliant
• Automotive grade with AEC-Q100 qualification
• Tape & Reel packaging for automated assembly
• Higher inventory availability (39,586 pcs)

BAW156VL Selection:

• Active product status
• ROHS3 compliant
• Automotive grade with AEC-Q100 qualification
• Tape & Reel packaging for automated assembly
• Lower inventory availability (4,022 pcs)

Both substitute parts maintain identical electrical and mechanical specifications to the BAW156/ZLR. The presence of automotive grade classification and AEC-Q100 qualification on both substitutes indicates enhanced reliability and quality assurance compared to the original obsolete part. Selection between BAW156,215 and BAW156VL should be based on supply chain availability, lead time requirements, and inventory levels.

Frequently Asked Questions (FAQ)

Q: Can BAW156,215 or BAW156VL be used as direct replacements for BAW156/ZLR in existing designs?

A: Yes. Both BAW156,215 and BAW156VL are parametric equivalents to BAW156/ZLR. All electrical parameters (reverse voltage, forward voltage, current ratings, recovery time, leakage current, and junction temperature) are identical. Both devices use the same SOT-23-3 package and surface mount configuration, enabling direct PCB substitution without design modification.

Q: What is the difference between BAW156,215 and BAW156VL?

A: Both parts are parametrically identical and share the same electrical and mechanical specifications. The primary differences are inventory levels (BAW156,215: 39,586 pcs; BAW156VL: 4,022 pcs) and packaging availability. Both are automotive grade with AEC-Q100 qualification and ROHS3 compliance.

Q: Why is the BAW156/ZLR classified as obsolete?

A: The BAW156/ZLR is listed as obsolete product status. The active substitutes BAW156,215 and BAW156VL represent the current production alternatives from Nexperia USA Inc. and should be used for new designs and ongoing production.

Q: Are there any compatibility concerns when substituting BAW156,215 or BAW156VL for BAW156/ZLR?

A: No compatibility concerns exist. Both substitute parts maintain identical package dimensions (TO-236-3, SC-59, SOT-23-3), pinout configuration (1 Pair Common Anode), and electrical performance specifications. PCB footprints and assembly processes require no modification.

Q: What is the significance of AEC-Q100 qualification on the substitute parts?

A: AEC-Q100 qualification indicates that BAW156,215 and BAW156VL meet automotive industry reliability and quality standards. This qualification is not specified for the obsolete BAW156/ZLR, representing an improvement in quality assurance for substitute parts.

Q: Are BAW156,215 and BAW156VL RoHS compliant?

A: Yes. Both substitute parts are ROHS3 compliant and carry unlimited Moisture Sensitivity Level (MSL 1), matching the compliance profile of the original BAW156/ZLR.
