COP472WM-3 Equivalent & Substitute Parts

Part Overview

The COP472WM-3 is an LCD driver integrated circuit manufactured by Texas Instruments, designed for 36-segment, 4.5-digit display applications. This device operates as a serial interface driver with a 20-SOIC surface mount package and supports supply voltages from 3V to 5.5V. The COP472WM-3 is classified as obsolete product status, making identification of functionally equivalent substitute parts essential for ongoing design support and component procurement in legacy systems and new designs requiring compatible alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the COP472WM-3 are identified based on strict electrical and mechanical parameter matching. The critical parameters determining substitution eligibility are:

• Display configuration (36 Segment, 4.5 Digits)
• Serial interface protocol
• Supply voltage range (3V ~ 5.5V)
• Supply current specification (250 µA)
• Operating temperature range (0°C ~ 70°C)
• Package type (20-SOIC with identical physical dimensions)
• Mounting technology (Surface Mount)

Parts meeting all these parameters are classified as direct substitutes. Packaging variations (such as tube versus alternative packaging formats) do not affect functional substitution eligibility when the core electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the COP472WM-3 and COP472WM-3/NOPB are functionally equivalent LCD driver circuits with identical electrical and mechanical specifications. The primary distinction between these parts is regulatory compliance status.

The COP472WM-3/NOPB variant carries ROHS3 compliance certification, whereas the base COP472WM-3 is RoHS non-compliant. For applications subject to RoHS regulatory requirements or environmental compliance mandates, the COP472WM-3/NOPB is the appropriate selection.

The COP472WM-3/NOPB exhibits a higher Moisture Sensitivity Level (MSL 3, 168 hours) compared to the COP472WM-3 (MSL 1, unlimited). This difference reflects handling and storage requirements but does not affect functional performance in deployed applications.

Both parts are classified as obsolete. Component selection should account for available inventory and long-term supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can COP472WM-3/NOPB be used as a direct replacement for COP472WM-3?

A: Yes. Both parts share identical electrical specifications, serial interface protocol, 36-segment 4.5-digit LCD driver configuration, supply voltage range (3V ~ 5.5V), supply current (250 µA), operating temperature range (0°C ~ 70°C), and 20-SOIC package dimensions. Functional substitution is direct.

Q: What is the difference between COP472WM-3 and COP472WM-3/NOPB?

A: The primary differences are RoHS compliance status and Moisture Sensitivity Level. The COP472WM-3/NOPB is ROHS3 compliant with MSL 3 (168 hours), while the COP472WM-3 is RoHS non-compliant with MSL 1 (unlimited). Electrical and mechanical specifications are identical.

Q: Which part should be selected for RoHS-regulated applications?

A: The COP472WM-3/NOPB is ROHS3 compliant and is the appropriate selection for applications subject to RoHS environmental directives.

Q: Are there packaging differences between these parts?

A: The COP472WM-3 is supplied in standard packaging, while the COP472WM-3/NOPB is supplied in tube packaging. Both use the identical 20-SOIC (0.295", 7.50mm Width) component package. Packaging format does not affect electrical performance or PCB compatibility.

Q: What does MSL 3 (168 hours) mean for the COP472WM-3/NOPB?

A: Moisture Sensitivity Level 3 specifies that the component must be used within 168 hours of package opening under controlled humidity conditions. This is a standard handling requirement for surface mount components and does not affect performance in sealed applications.

Q: Are both parts still in production?

A: Both the COP472WM-3 and COP472WM-3/NOPB are classified as obsolete. Component selection should prioritize available inventory from authorized distributors.
