ZXCT199B2DW-7 Equivalent & Substitute Parts

Part Overview

The ZXCT199B2DW-7 is an integrated circuit current monitor manufactured by Diodes Incorporated, classified as a Power Management (PMIC) component. This high/low-side current monitor operates across a wide input voltage range of 2.7V to 26V and is qualified for automotive applications under AEC-Q100 standards. The device is housed in a 6-TSSOP (SOT-363) surface mount package and maintains active product status with full ROHS3 compliance.

Substitute parts are necessary when primary component availability is limited, supply chain disruptions occur, or inventory optimization is required across manufacturing operations. The ZXCT199 series provides multiple equivalent variants that maintain identical electrical and mechanical specifications, enabling seamless design flexibility.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts within the ZXCT199 series maintain identical electrical and mechanical specifications as the primary ZXCT199B2DW-7 component. Substitution eligibility is determined by the following critical parameters:

Substitution Criteria:

• Input voltage range: 2.7V ~ 26V (identical across all variants)
• Operating temperature range: -40°C ~ 125°C (identical across all variants)
• Sensing method: High/Low-Side (identical across all variants)
• Package type: SOT-363 (identical across all variants)
• Automotive grade qualification: AEC-Q100 (identical across all variants)
• Surface mount mounting type (identical across all variants)
• RoHS3 compliance status (identical across all variants)
• Moisture sensitivity level: MSL 1 (identical across all variants)

The ZXCT199B2DW-7, ZXCT199B3DW-7, ZXCT199C1DW-7, ZXCT199C2DW-7, and ZXCT199C3DW-7 are fully interchangeable within applications requiring current monitoring functionality across the specified voltage and temperature ranges. Part number variations reflect internal die or trim code differences that do not affect functional performance in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Are all ZXCT199 variants electrically identical?

A: Yes. ZXCT199B2DW-7, ZXCT199B3DW-7, ZXCT199C1DW-7, ZXCT199C2DW-7, and ZXCT199C3DW-7 share identical input voltage range (2.7V ~ 26V), operating temperature range (-40°C ~ 125°C), sensing method (High/Low-Side), and automotive qualification (AEC-Q100). Part number variations reflect internal die or trim code differences that do not affect functional performance.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All variants are housed in the SOT-363 package with identical pinout and electrical specifications. Direct substitution is supported without design modification.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 indicates unlimited moisture sensitivity level, meaning the component has no moisture-related shelf life restrictions under standard storage conditions. This simplifies inventory management and reduces risk of moisture-induced failures during storage.

Q: Are all variants ROHS3 compliant?

A: Yes. All ZXCT199 series parts listed are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for automotive and industrial applications.

Q: What is the difference between high-side and low-side current monitoring?

A: This device supports both high-side and low-side sensing methods, enabling current monitoring across a wide range of circuit topologies. The specific application determines which sensing configuration is appropriate.
