Substitute Part Grouping Explanation

Substitution of the 74HCT10D,652 is determined by strict equivalence across the following critical parameters:

Logic configuration: 3-channel NAND gate with 3 inputs per channel
Electrical specifications: 4.5V ~ 5.5V supply voltage, 2 µA quiescent current, 4mA output drive, 24ns propagation delay
Input logic thresholds: 0.8V low, 2V high
Operating temperature range: minimum -40°C (main part) to -55°C (substitute parts)
Package type: 14-SOIC surface mount
Base product series: 74HCT10

All substitute parts maintain identical logic functionality and electrical performance within the specified parameters. Differences in product status, RoHS compliance, and manufacturer do not affect electrical interchangeability.

Engineering Selection Recommendations

CD74HCT10M96 (Texas Instruments) is the primary substitute for new designs and procurement. This part carries Active product status, ensuring long-term availability and manufacturer support. It maintains ROHS3 compliance and MSL Level 1 rating, meeting modern environmental and reliability standards. The extended operating temperature range of -55°C ~ 125°C provides additional margin for demanding applications.

CD74HCT10MT (Texas Instruments) serves as a secondary option with identical electrical and compliance specifications to CD74HCT10M96. Last Time Buy status indicates limited future availability; this part is suitable for existing inventory replenishment but not recommended for new long-term procurement.

CD74HCT10M (Harris Corporation) is electrically equivalent but carries RoHS non-compliance status and obsolete product classification. This part should be selected only when RoHS exemptions are documented and approved for the application.

The 74HCT10D,652 original part is obsolete and should not be specified for new designs. Existing designs using this part number should transition to CD74HCT10M96 to ensure supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts pin-compatible with the 74HCT10D,652?

A: Yes. All substitute parts use the 14-SOIC package with identical pinout and footprint. Direct PCB replacement is possible without layout modifications.

Q: What is the difference between the Texas Instruments variants CD74HCT10M96 and CD74HCT10MT?

A: Both parts are electrically identical with matching specifications and compliance ratings. The primary difference is packaging: CD74HCT10M96 is supplied in Tape & Reel format, while CD74HCT10MT is also in Tape & Reel. Product status differs—CD74HCT10M96 is Active, while CD74HCT10MT is Last Time Buy. For new designs, CD74HCT10M96 is preferred due to Active status.

Q: Can the Harris CD74HCT10M be used in applications requiring RoHS compliance?

A: No. The CD74HCT10M is RoHS non-compliant. Applications with RoHS requirements must use CD74HCT10M96 or CD74HCT10MT from Texas Instruments.

Q: Does the extended operating temperature range of substitute parts (-55°C vs -40°C) affect circuit design?

A: No. The substitute parts' wider temperature range is a superset of the original specification. Designs validated for -40°C ~ 125°C operation remain valid with substitute parts rated to -55°C ~ 125°C.

Q: What is the MSL rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control. The 74HCT10D,652, CD74HCT10M96, and CD74HCT10MT all carry MSL 1, eliminating moisture-related handling constraints during storage and assembly.

Q: Is the 74HCT10 base product number the same across all variants?

A: Yes. All parts share the 74HCT10 base product number, confirming functional equivalence. Suffix variations (D, M, M96, MT) indicate manufacturer and packaging differences only.
