BA82903YFVM-CTR Equivalent & Substitute Parts

Part Overview

The BA82903YFVM-CTR is a dual general-purpose comparator manufactured by Rohm Semiconductor in an 8-MSOP surface-mount package. This linear integrated circuit features open-collector outputs and operates across a wide supply voltage range of 2V to 36V (single supply) or ±1V to ±18V (dual supply). The device is classified as Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified to provide design flexibility when the primary part is unavailable or when alternative packaging or performance characteristics are required for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BA82903YFVM-CTR are identified based on functional equivalence within the general-purpose comparator category. The substitution logic is based on the following critical parameters:

Functional Compatibility Criteria:

• Dual-element comparator configuration (2 independent comparators per package)
• General-purpose comparator classification
• Surface-mount packaging technology
• Operating temperature range of -40°C to 125°C
• Active product status with current manufacturing availability
• RoHS3 compliance and REACH unaffected status

Package Variation Allowance: The BA82903YFVM-CTR is available in 8-MSOP packaging. Substitute parts may utilize alternative 8-pin surface-mount packages (such as 8-SOIC) provided the pin count, mounting technology, and functional pinout remain compatible with the application requirements.

Electrical Parameter Tolerance: Substitute parts must operate within overlapping supply voltage ranges and maintain comparable input/output electrical characteristics suitable for general-purpose comparator applications. Variations in propagation delay, input offset voltage, and quiescent current are acceptable within the bounds of general-purpose comparator specifications.

Engineering Selection Recommendations

BA82903YFVM-CTR (Primary Part): The BA82903YFVM-CTR remains the primary selection when the 8-MSOP package footprint is required and the extended supply voltage range (up to 36V single supply) is necessary. This part is Active status, RoHS3 compliant, and maintains REACH unaffected designation. The open-collector output configuration and higher output current capability (16mA typical) support direct logic-level interfacing in applications requiring robust drive capability.

TS393DR2G (Substitute Part): The TS393DR2G from onsemi serves as a functional substitute when 8-SOIC packaging is acceptable and supply voltage requirements do not exceed 16V. This part is also Active status and RoHS3 compliant with REACH unaffected designation. The TS393DR2G exhibits superior input offset voltage (1.4mV typical versus 5mV maximum) and lower input bias current (600pA versus 0.25µA), making it suitable for precision measurement applications. The lower quiescent current (15µA maximum) and reduced output current (1mA typical) indicate lower power consumption characteristics. The MSL rating of 1 (Unlimited) provides superior moisture tolerance compared to the BA82903YFVM-CTR MSL rating of 3.

Selection Criteria:

• Choose BA82903YFVM-CTR for high-voltage applications (>16V supply) or when 8-MSOP package is mandated by PCB layout constraints
• Choose TS393DR2G when 8-SOIC package is compatible, supply voltage remains below 16V, and lower power consumption or improved input offset characteristics are beneficial
• Both parts maintain identical operating temperature range and compliance certifications

Frequently Asked Questions (FAQ)

Q: Can the TS393DR2G directly replace the BA82903YFVM-CTR in existing designs?

A: Direct replacement depends on two factors: (1) PCB footprint compatibility with 8-SOIC versus 8-MSOP packages, and (2) supply voltage requirements. If the application operates at 16V or below and the PCB layout accommodates 8-SOIC spacing, the TS393DR2G is functionally compatible. If the design requires supply voltages above 16V or mandates 8-MSOP footprint, the BA82903YFVM-CTR must be used.

Q: What is the primary difference in output characteristics between these parts?

A: The BA82903YFVM-CTR provides 16mA typical output current, while the TS393DR2G provides 1mA typical output current. The BA82903YFVM-CTR output type is specified as open-collector. Applications requiring direct TTL/CMOS logic interfacing with minimal external pull-up resistors should use the BA82903YFVM-CTR. Applications with high-impedance loads or requiring lower power dissipation may use the TS393DR2G.

Q: Are there supply voltage limitations when substituting parts?

A: Yes. The BA82903YFVM-CTR operates from 2V to 36V (single supply) or ±1V to ±18V (dual supply). The TS393DR2G operates from 2.7V to 16V. If the application requires supply voltages exceeding 16V, the TS393DR2G cannot be used. Verify supply voltage specifications before substitution.

Q: How do the input offset voltage specifications compare?

A: The BA82903YFVM-CTR specifies a maximum input offset voltage of 5mV at 5V supply. The TS393DR2G specifies a typical input offset voltage of 1.4mV. For precision threshold detection or low-level signal comparison, the TS393DR2G provides superior offset performance. For general-purpose switching applications, both parts are acceptable.

Q: What is the significance of the MSL (Moisture Sensitivity Level) difference?

A: The BA82903YFVM-CTR has MSL 3 (168 hours), while the TS393DR2G has MSL 1 (Unlimited). MSL 1 indicates superior moisture tolerance and eliminates the requirement for bake-out procedures before reflow soldering. For high-volume manufacturing or applications with extended storage periods, the TS393DR2G offers reduced handling complexity.

Q: Can both parts be used interchangeably in the same circuit design?

A: Interchangeability requires verification of three parameters: (1) supply voltage range compatibility, (2) PCB package footprint accommodation, and (3) output current requirements. If all three parameters align with the TS393DR2G specifications, the parts are interchangeable. If any parameter exceeds TS393DR2G limits, the BA82903YFVM-CTR must be retained.

Q: What is the propagation delay difference and does it affect circuit performance?

A: The BA82903YFVM-CTR specifies 400ns typical propagation delay, while the TS393DR2G specifies 2.1µs maximum propagation delay. For high-speed comparator applications or circuits with tight timing requirements below 2.1µs, the BA82903YFVM-CTR provides faster response. For general-purpose threshold detection or low-frequency signal monitoring, both parts are functionally equivalent.
