Key Parameters

Substitute Part Grouping Explanation

Substitute parts for CD74HC4514ENG4 are selected strictly based on matching the following key parameters: functional type (Decoder/Demultiplexer), circuit configuration (1 x 4:16), output current rating, voltage supply range, operating temperature range, series, RoHS and REACH compliance, and MSL rating. The mounting type and package/case differ between through-hole and surface-mount variants but maintain equivalent electrical functionality for designs flexible to alternate packages.

Parameter Comparison

Engineering Selection Recommendations

CD74HC4514ENG4 is obsolete, while CD74HC4514M96 is active and available. Both parts comply with ROHS3 and REACH requirements and have an MSL rating of 1 (Unlimited). Substitute selection is supported by identical electrical, functional, and compliance parameters. Package and mounting type must be considered at the PCB design level. For compliance, electrical specifications, supply voltage, and temperature range, CD74HC4514M96 is an appropriate substitute.

Frequently Asked Questions (FAQ)

Q1: What are the most important criteria for substituting CD74HC4514ENG4?
Substitution requires matching the logic function, output current, voltage supply range, temperature range, and compliance certifications. Mechanical considerations such as package type and mounting method must be aligned with board design requirements.

Q2: Can CD74HC4514M96 replace CD74HC4514ENG4 in an existing design?
CD74HC4514M96 matches all electrical and compliance parameters but differs in package and mounting type (Surface Mount vs. Through Hole). PCB layout modifications are necessary to accommodate the alternate package.

Q3: Are both parts ROHS and REACH compliant for international procurement and manufacturing?
Both CD74HC4514ENG4 and CD74HC4514M96 are ROHS3 compliant and REACH unaffected, supporting international environmental and safety standards.

Q4: Is the operating temperature range identical for substituting these parts?
Both parts share an operating temperature range of -55°C to 125°C.

Q5: How does mounting type affect substitution?
Through Hole (CD74HC4514ENG4) and Surface Mount (CD74HC4514M96) are not cross-compatible at the board level without redesign. Substitution is feasible where package changes are permissible.
