Substitute Part Grouping Explanation

Substitution of the SN74HC10D is determined by strict equivalence across the following critical parameters:

Logic function: 3-channel, 3-input NAND gate
Supply voltage range: 2V ~ 6V minimum
Output current capability: 5.2mA minimum for both high and low states
Propagation delay: 16ns maximum at 6V, 50pF load
Package type: 14-SOIC surface mount
Input logic thresholds: Low 0.5V ~ 1.8V, High 1.5V ~ 4.2V
Quiescent current: 2 µA maximum
RoHS3 compliance and MSL Level 1

Substitute parts are grouped by availability status and operating temperature range. Direct substitutes maintain identical electrical specifications and packaging. Upgrade substitutes extend operating temperature range or add automotive qualification while maintaining core electrical parameters.

Engineering Selection Recommendations

SN74HC10DR is the direct substitute for the discontinued SN74HC10D. Both parts are manufactured by Texas Instruments with identical electrical specifications and operating temperature range (-40°C ~ 85°C). The primary difference is packaging format: SN74HC10DR is supplied in Cut Tape and Digi-Reel format with higher inventory availability (22,700 units), whereas the original SN74HC10D was supplied in Tube format. Both maintain ROHS3 compliance and MSL Level 1 rating.

74HC10D,653 and 74HC10D-Q100J are upgrade substitutes manufactured by Nexperia USA Inc. Both extend the operating temperature range to -40°C ~ 125°C, providing enhanced thermal performance for applications requiring wider temperature operation. The 74HC10D-Q100J includes AEC-Q100 automotive qualification, suitable for automotive-grade applications. These parts maintain all core electrical specifications and ROHS3 compliance.

MC74HC10ADR2G is a manufacturer-recommended substitute from onsemi. This part offers the widest operating temperature range (-55°C ~ 125°C) and reduced quiescent current (1 µA versus 2 µA), providing superior low-power performance. All other electrical parameters remain equivalent. ROHS3 compliance and MSL Level 1 rating are maintained.

All substitute parts are currently active in production and available in commercial quantities. Selection should be based on application temperature requirements, automotive qualification needs, and packaging format preferences.

Frequently Asked Questions (FAQ)

Q: Can SN74HC10DR be used as a direct replacement for SN74HC10D?
