Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM74HC4514WMX are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Functional Equivalence Criteria:

• Circuit configuration: 1 x 4:16 decoder/demultiplexer
• Output current specifications: 5.2mA high and low
• Voltage supply range: 2V ~ 6V
• Series classification: 74HC logic family

Mechanical Compatibility Criteria:

• Package type: 24-SOIC surface mount
• Package dimensions: 0.295" width, 7.50mm width
• Mounting type: Surface mount

Environmental & Compliance Criteria:

• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• RoHS compliance status

The substitute parts CD74HC4514M and CD74HC4514M96, both manufactured by Texas Instruments, meet these functional and mechanical requirements. Both parts maintain the 1 x 4:16 circuit configuration, identical output current ratings, compatible voltage supply range, and 24-SOIC package specifications.

Engineering Selection Recommendations

CD74HC4514M96 (Texas Instruments) - Primary Selection

The CD74HC4514M96 is the preferred substitute for the obsolete MM74HC4514WMX. This part maintains active product status with ROHS3 compliance certification. The extended operating temperature range of -55°C ~ 125°C provides broader environmental coverage compared to the original part's -40°C ~ 85°C specification. The CD74HC4514M96 is supplied in Cut Tape and Digi-Reel packaging formats, supporting both prototype and production volume requirements.

CD74HC4514M (Texas Instruments) - Secondary Selection

The CD74HC4514M serves as an alternative substitute with identical functional and mechanical specifications to the CD74HC4514M96. This part carries Last Time Buy status and is supplied in Tube packaging. Selection of this variant should account for its discontinuation trajectory and reduced long-term availability compared to the active CD74HC4514M96.

Both Texas Instruments substitutes are functionally equivalent to the MM74HC4514WMX within the specified electrical and mechanical parameters. The choice between CD74HC4514M and CD74HC4514M96 depends on production volume requirements, packaging preferences, and long-term supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4514M96 directly replace MM74HC4514WMX in existing designs?

A: Yes. Both parts share identical circuit configuration (1 x 4:16), output current specifications (5.2mA), voltage supply range (2V ~ 6V), and 24-SOIC package dimensions. Pin-to-pin compatibility is maintained.

Q: What is the difference between CD74HC4514M and CD74HC4514M96?

A: Both parts are functionally and mechanically identical. The primary differences are product status (Last Time Buy vs. Active) and packaging format (Tube vs. Cut Tape/Digi-Reel). CD74HC4514M96 is recommended for new designs due to active status.

Q: Does the extended operating temperature range of the substitute parts affect compatibility?

A: No. The CD74HC4514M and CD74HC4514M96 operating range of -55°C ~ 125°C encompasses the original MM74HC4514WMX range of -40°C ~ 85°C. Extended temperature capability does not impact compatibility in applications within the original specification limits.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both CD74HC4514M and CD74HC4514M96 are ROHS3 compliant. The original MM74HC4514WMX RoHS status was not specified in available documentation.

Q: What packaging options are available for substitute parts?

A: CD74HC4514M is supplied in Tube packaging. CD74HC4514M96 is supplied in Cut Tape and Digi-Reel formats. Selection depends on production volume and assembly process requirements.

Q: Is the 24-SOP package of the original part compatible with 24-SOIC footprints?

A: Yes. The MM74HC4514WMX 24-SOP and substitute parts' 24-SOIC packages share identical 0.295" (7.50mm) width specifications and are mechanically compatible with standard 24-SOIC PCB footprints.
