Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HCT165D,652 is determined by the following critical parameters:

• Logic type and function (8-bit shift register, parallel or serial to serial conversion)
• Output type (complementary)
• Supply voltage range (4.5V ~ 5.5V)
• Package and case dimensions (16-SOIC, 0.154" width, 3.90mm)
• Mounting type (surface mount)
• RoHS and environmental compliance (ROHS3 Compliant, MSL 1)

All substitute parts listed maintain identical functional specifications and package compatibility. Differences in operating temperature range and product status are noted for design consideration.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, CD74HCT165M96 is the preferred substitute. This part is classified as active and maintains full functional and electrical equivalence to the 74HCT165D,652. The extended operating temperature range (-55°C ~ 125°C) provides additional margin for demanding environments.

CD74HCT165M is functionally equivalent but carries a discontinued status at DiGi Electronics, making long-term availability uncertain. This part may be suitable for legacy system maintenance where existing inventory is available.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT165M96 be used as a direct replacement for 74HCT165D,652?

A: Yes. Both parts are 8-bit shift registers with identical logic function, output type, supply voltage range, and 16-SOIC package dimensions. Pin-to-pin compatibility is maintained.

Q: What is the difference between CD74HCT165M and CD74HCT165M96?

A: Both are Texas Instruments 74HCT165 shift registers with identical electrical specifications and package. The primary difference is product status: CD74HCT165M96 is active, while CD74HCT165M is discontinued at DiGi Electronics. CD74HCT165M96 is available in Cut Tape and Digi-Reel packaging with significantly higher inventory levels.

Q: Does the extended operating temperature range of the substitute parts affect compatibility?

A: No. The substitute parts operate across -55°C ~ 125°C, which encompasses the original part's -40°C ~ 125°C range. This provides additional thermal margin without affecting electrical performance within the original specification window.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), matching the original part's environmental certifications.

Q: What packaging options are available for substitute parts?

A: CD74HCT165M is supplied in Tube packaging. CD74HCT165M96 is available in Cut Tape (CT) and Digi-Reel packaging, offering flexibility for different production volumes and handling requirements.
