Substitute Part Grouping Explanation

Substitution of the DM74ALS03BMX is determined by strict equivalence across the following parameters:

• Logic type and circuit configuration (4-channel 2-input NAND gate with open collector output)
• Electrical specifications (4.5V ~ 5.5V supply, 8mA output current, 50ns propagation delay, input logic levels)
• Package type (14-SOIC surface mount)
• Operating temperature range (0°C ~ 70°C)

The substitute parts identified below maintain identical electrical and mechanical specifications, differing only in manufacturer, product status, and packaging format (tube versus tape & reel).

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the DM74ALS03BMX, the SN74ALS03BDR manufactured by Texas Instruments is the primary substitute. This part maintains active product status, ensuring long-term availability and supply chain stability. The SN74ALS03BDR is ROHS3 compliant and supplied in tape & reel format, suitable for automated assembly processes.

The SN74ALS03BD, also from Texas Instruments, serves as an alternative substitute with identical electrical and mechanical specifications. This part carries Last Time Buy status and is supplied in tube packaging, making it suitable for lower-volume applications or manual assembly workflows.

Both Texas Instruments substitutes are electrically and mechanically interchangeable with the DM74ALS03BMX across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS03BD and SN74ALS03BDR be used interchangeably with DM74ALS03BMX?

A: Yes. Both parts are electrically and mechanically equivalent. The primary difference is packaging format: SN74ALS03BD is supplied in tube packaging, while SN74ALS03BDR is supplied in tape & reel format. Selection depends on assembly method and procurement volume requirements.

Q: What is the significance of the product status differences?

A: DM74ALS03BMX is obsolete, indicating no further manufacturing. SN74ALS03BD is Last Time Buy, meaning limited availability remains. SN74ALS03BDR is Active, ensuring continued production and supply availability. For new designs or long-term applications, SN74ALS03BDR is recommended.

Q: Are there any compliance differences between these parts?

A: The Texas Instruments substitutes (SN74ALS03BD and SN74ALS03BDR) are ROHS3 compliant. Compliance status for the DM74ALS03BMX is not specified in the provided data. Both substitutes maintain REACH Unaffected status, consistent with the original part.

Q: Does packaging format affect electrical performance?

A: No. Tape & reel and tube packaging formats contain identical components. Packaging selection is based on assembly process requirements and procurement volume, not electrical characteristics.

Q: What parameters must remain identical for substitution?

A: Logic type, circuit count, input count, open collector feature, supply voltage range (4.5V ~ 5.5V), output current (8mA), input logic levels, propagation delay (50ns @ 5V, 50pF), operating temperature range (0°C ~ 70°C), and 14-SOIC package must all remain unchanged for direct substitution.
