Key Parameters

Substitute Part Grouping Explanation

Substitution of the Parallax Inc. 602-00010 is determined by the following critical parameters:

Electrical Compatibility:

• Logic Type: Shift Register (1 Element, 8 Bit)
• Supply Voltage Range: 2V ~ 6V
• Series Classification: 74HC

Mechanical Compatibility:

• Package Type: 16-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

Functional Compatibility:

• Parallel-to-Serial conversion capability
• Pin-compatible 16-DIP footprint

The Texas Instruments CD74HC165E satisfies all substitution criteria. While the CD74HC165E supports an extended function set (Parallel or Serial to Serial) and broader operating temperature range (-55°C to 125°C), it maintains full backward compatibility with the original part's parallel-to-serial operation within the specified voltage and temperature envelope of the 602-00010.

Parameter Comparison

Engineering Selection Recommendations

The Texas Instruments CD74HC165E is the direct functional equivalent for the Parallax Inc. 602-00010. Selection of the CD74HC165E is supported by the following factors:

Electrical Equivalence: Both parts operate within the identical 2V to 6V supply voltage range and belong to the 74HC logic family, ensuring signal compatibility and timing characteristics suitable for parallel-to-serial shift register applications.

Mechanical Compatibility: The CD74HC165E is packaged in a 16-DIP (0.300", 7.62mm) through-hole configuration, providing direct pin-for-pin compatibility with existing PCB layouts and socket installations designed for the 602-00010.

Product Availability: The CD74HC165E maintains active production status with established supply channels, providing long-term availability for both replacement and new design applications.

Compliance and Certification: The CD74HC165E carries RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component procurement.

Extended Operating Range: The CD74HC165E supports an operating temperature range of -55°C to 125°C, which encompasses the original part's -40°C to 85°C specification, providing additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the Texas Instruments CD74HC165E directly replace the Parallax Inc. 602-00010 in existing designs?

A: Yes. The CD74HC165E is pin-compatible and electrically equivalent within the 2V to 6V supply voltage range. Both parts are 16-DIP through-hole packages with identical pinout and functional operation for parallel-to-serial conversion.

Q: What is the difference between the "Parallel to Serial" function of the 602-00010 and the "Parallel or Serial to Serial" function of the CD74HC165E?

A: The CD74HC165E supports both parallel-to-serial and serial-to-serial operation modes through its control pin configuration. When configured for parallel-to-serial operation, it functions identically to the 602-00010. The extended capability does not affect backward compatibility.

Q: Are there any temperature-related limitations when substituting the CD74HC165E?

A: No. The CD74HC165E operates across -55°C to 125°C, which fully encompasses the original part's -40°C to 85°C range. Applications operating within the original temperature specification will function without thermal constraints.

Q: Is the CD74HC165E available in the same packaging format?

A: Yes. The CD74HC165E is supplied in a 16-DIP (0.300", 7.62mm) through-hole package, identical to the 602-00010. Both parts use standard DIP socket compatibility.

Q: What is the inventory status of the CD74HC165E?

A: The CD74HC165E maintains active production status with 1280 pieces available in new original condition. The part is supplied in tube packaging by Texas Instruments.

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

A: The CD74HC165E carries RoHS3 compliance and REACH unaffected status. The original 602-00010 carries MSL 1 (Unlimited) rating. Both parts share the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
