Equivalent & Substitute Parts for COP472WM-3/63

Part Overview

The COP472WM-3/63 from Texas Instruments is classified under Power Management (PMIC), specifically as an LCD Driver IC in a 20-SOIC (0.295", 7.50mm Width) package. The device is designed for driving 36 segment LCDs with a serial interface and supports display configurations of up to 4.5 digits. The part is currently obsolete, necessitating the identification of substitute models to maintain product lifecycle or support ongoing legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for LCD Driver ICs such as COP472WM-3/63 requires strict equivalence in key electrical and mechanical parameters: display type (LCD), segment configuration (36 Segment), interface (Serial), digits supported (4.5), supply current (250 µA), supply voltage range (3V ~ 5.5V), operating temperature range (0°C ~ 70°C), mounting type (Surface Mount), and package (20-SOIC with 0.295", 7.50mm width). Only those alternatives fully matching these criteria are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

Based on the product status, COP472WM-3/63 is obsolete and non-RoHS compliant, whereas COP472WM-3/NOPB is obsolete but ROHS3 compliant. Both are REACH unaffected and share the same series, electrical parameters, and mechanical packaging. Substitution is permitted in applications where ROHS3 compliance is required and where inventory attributes and manufacturer continuity are necessary.

Frequently Asked Questions (FAQ)

Q1: What qualifies COP472WM-3/NOPB as a substitute for COP472WM-3/63?
A1: COP472WM-3/NOPB matches the COP472WM-3/63 in all key electrical and mechanical parameters, including display type, segment configuration, interface, digits supported, supply current, voltage range, operating temperature, mounting type, series, and package.

Q2: Are there differences in compliance or environmental certifications?
A2: COP472WM-3/NOPB is ROHS3 compliant, whereas COP472WM-3/63 is RoHS non-compliant. Both are REACH unaffected and obsolete.

Q3: Is the package size and footprint the same?
A3: Both models use the 20-SOIC (0.295", 7.50mm Width) footprint, maintaining mechanical compatibility for surface mount assembly.

Q4: Is there any difference in electrical specification that would prevent direct substitution?
A4: There are no differences in the electrical specifications provided; all relevant electrical parameters match.

Q5: Should inventory or packaging differences be considered when selecting a substitute?
A5: Both parts are listed as New Original In Stock, with COP472WM-3/NOPB supplied in tube packaging. COP472WM-3/63 is listed without specific packaging. Ensure that supply form matches production requirements.
