Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC4514M is determined by strict equivalence across the following critical parameters:

• Circuit configuration: 1 x 4:16 decoder/demultiplexer function
• Package type: 24-SOIC surface mount
• Voltage supply range: 2V ~ 6V
• Output current specifications: 5.2mA high and low
• Operating temperature range: -55°C ~ 125°C
• RoHS and REACH compliance status

The identified substitute parts maintain identical electrical and mechanical specifications, differing only in packaging format (Cut Tape/Digi-Reel versus Tube) and product lifecycle status. All substitutes are manufactured by Texas Instruments within the 74HC series.

Parameter Comparison

Engineering Selection Recommendations

CD74HC4514M96 is the primary substitute for the CD74HC4514M. Both parts are manufactured by Texas Instruments with identical electrical and mechanical specifications. The CD74HC4514M96 maintains Active product status, ensuring long-term availability and supply chain continuity. The difference in packaging format (Cut Tape/Digi-Reel versus Tube) does not affect functional compatibility and accommodates different procurement and assembly workflows.

CD74HC4515M is a parametric equivalent offering identical functional and electrical characteristics. This part is also manufactured by Texas Instruments within the 74HC series. However, CD74HC4515M carries Last Time Buy status, similar to the original CD74HC4514M, and therefore does not provide improved supply continuity. Selection of CD74HC4515M should be based on specific packaging or inventory requirements rather than lifecycle considerations.

Both substitute parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4514M96 be used as a direct replacement for CD74HC4514M?

A: Yes. CD74HC4514M96 is functionally and electrically equivalent to CD74HC4514M. Both parts share identical circuit configuration (1 x 4:16), package type (24-SOIC), voltage supply range (2V ~ 6V), output current specifications (5.2mA), and operating temperature range (-55°C ~ 125°C). The only difference is packaging format: CD74HC4514M96 is supplied in Cut Tape/Digi-Reel format, while CD74HC4514M is supplied in Tube format.

Q: What is the difference between CD74HC4514M and CD74HC4515M?

A: Both parts are 1 x 4:16 decoder/demultiplexer circuits in 24-SOIC packages with identical electrical specifications. The primary difference is the base product number designation (74HC4514 versus 74HC4515). Both maintain the same voltage supply range, output current, and operating temperature specifications. Both are currently in Last Time Buy status.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (Tube versus Cut Tape/Digi-Reel) does not affect electrical performance or functional characteristics. The difference is purely logistical, relating to how components are supplied and handled during procurement and assembly processes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CD74HC4514M, CD74HC4514M96, and CD74HC4515M are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute part offers the best supply continuity?

A: CD74HC4514M96 is the recommended choice for supply continuity. This part maintains Active product status, indicating ongoing manufacturing and availability. Both CD74HC4514M and CD74HC4515M are in Last Time Buy status, indicating limited future availability.
