Substitute Part Grouping Explanation

Substitution of the DM7414N is determined by strict equivalence across the following parameters:

• Logic type and circuit configuration (6-channel inverter with Schmitt trigger)
• Electrical specifications (supply voltage, output current, input logic levels, propagation delay)
• Package form factor (14-DIP through-hole mounting)
• Series classification (7400 logic family)

The SN7414N from Texas Instruments meets all these criteria. Both parts share identical electrical performance characteristics, operate within the same supply voltage range, and are housed in mechanically compatible 14-DIP packages. The substitution is based on functional and electrical equivalence, not on design preference or performance enhancement.

Parameter Comparison

Engineering Selection Recommendations

The SN7414N is the direct functional equivalent of the DM7414N. Selection between these parts should be based on the following factors:

Product Status: The DM7414N is obsolete, whereas the SN7414N maintains active production status. For new designs or ongoing procurement, the SN7414N is the appropriate choice due to continued availability and manufacturer support.

Compliance Considerations: The SN7414N is ROHS3 compliant, while the DM7414N is non-compliant. Applications subject to RoHS regulations require the SN7414N. Both parts are REACH unaffected and classified under ECCN EAR99.

Electrical Equivalence: All electrical parameters are identical between the two parts, ensuring direct functional substitution without circuit modification or performance degradation.

Package Compatibility: Both parts utilize the same 14-DIP through-hole package with identical pin spacing and mechanical dimensions, allowing direct board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can the SN7414N replace the DM7414N in existing designs?

A: Yes. The SN7414N is electrically and mechanically equivalent to the DM7414N. All electrical parameters, including supply voltage, output current, input logic levels, and propagation delay, are identical. The 14-DIP package dimensions are the same, permitting direct substitution without circuit redesign.

Q: What is the primary reason to substitute the DM7414N?

A: The DM7414N is classified as obsolete. The SN7414N, manufactured by Texas Instruments, is an active product with ongoing availability and manufacturer support, making it the recommended choice for new procurement and design continuity.

Q: Are there package variations between these parts?

A: Both the DM7414N and SN7414N are supplied in 14-DIP through-hole packages with identical mechanical specifications (0.300", 7.62mm). No package conversion is required for substitution.

Q: Does the SN7414N meet RoHS requirements?

A: Yes. The SN7414N is ROHS3 compliant. The DM7414N is non-compliant. Applications requiring RoHS certification must use the SN7414N.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts operate at 4.75V to 5.25V supply voltage, provide identical output current ratings (800µA high, 16mA low), maintain the same input logic thresholds (0.6V low, 2V high), and deliver 22ns maximum propagation delay at 5V with 15pF load.
