Substitute Part Grouping Explanation

The SN74ALS04BN qualifies as a direct substitute for the DM74ALS04BN based on the following criteria:

• Logic Function: Both parts implement 6-channel inverter logic with identical circuit configuration
• Electrical Specifications: Supply voltage range (4.5V ~ 5.5V), output current ratings (400µA, 8mA), input logic levels (0.8V low, 2V high), and propagation delay (11ns @ 5V, 50pF) are identical
• Package Compatibility: Both use 14-DIP (0.300", 7.62mm) through-hole packaging, ensuring mechanical and electrical compatibility on PCBs designed for the original part
• Series Alignment: Both belong to the 74ALS logic family, maintaining functional consistency within the same product line
• Operating Temperature Range: Identical 0°C ~ 70°C operating range ensures thermal compatibility

Engineering Selection Recommendations

The SN74ALS04BN from Texas Instruments is the recommended substitute for the obsolete DM74ALS04BN. Selection rationale is based on the following factors:

• Product Status: The SN74ALS04BN maintains active product status with ongoing manufacturer support, ensuring long-term availability and supply chain stability compared to the obsolete DM74ALS04BN
• Compliance Certifications: The SN74ALS04BN is RoHS3 compliant, meeting modern regulatory requirements for electronic components. Both parts maintain REACH Unaffected status and EAR99 export classification
• Electrical Equivalence: Complete parameter alignment across all specified electrical characteristics eliminates the need for circuit redesign or validation testing
• Package Compatibility: Identical 14-DIP through-hole packaging enables direct PCB substitution without layout modifications

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS04BN be used as a direct replacement for the DM74ALS04BN without circuit modifications?

A: Yes. The SN74ALS04BN is electrically and mechanically equivalent to the DM74ALS04BN. All electrical parameters, including supply voltage, output current, input logic levels, and propagation delay, are identical. The 14-DIP package dimensions are the same, allowing direct PCB substitution.

Q: What is the primary reason for substituting the DM74ALS04BN?

A: The DM74ALS04BN is classified as obsolete, which creates supply chain risk and limits long-term availability. The SN74ALS04BN maintains active product status, ensuring reliable sourcing for current and future production.

Q: Are there any compliance differences between the two parts?

A: The SN74ALS04BN is RoHS3 compliant, while the DM74ALS04BN does not specify RoHS status. Both parts are REACH Unaffected and carry EAR99 export classification. For applications requiring RoHS compliance, the SN74ALS04BN is the appropriate choice.

Q: Do the parts have different moisture sensitivity levels?

A: Yes. The DM74ALS04BN has a Moisture Sensitivity Level (MSL) of 1 (Unlimited), while the SN74ALS04BN lists MSL as Not Applicable. This difference does not affect substitution compatibility for standard through-hole assembly processes.

Q: Are the packaging formats identical?

A: Both parts use 14-DIP (0.300", 7.62mm) through-hole packaging. The DM74ALS04BN specifies 14-MDIP, while the SN74ALS04BN specifies 14-PDIP. Both designations refer to the same physical package format and are mechanically compatible on standard PCBs.
