CD74HC163M Equivalent & Substitute Parts

Part Overview

The CD74HC163M is a 4-bit binary counter IC manufactured by Texas Instruments, housed in a 16-SOIC surface mount package. This logic component functions as a synchronous, positive edge-triggered counter with a maximum count rate of 24 MHz and operates across a supply voltage range of 2 V to 6 V. The CD74HC163M is currently in Last Time Buy status, indicating limited availability and the necessity to identify functionally equivalent alternatives for ongoing design requirements and production planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC163M is determined by strict equivalence across the following critical parameters:

• Logic Function: Binary counter with identical 4-bit configuration
• Electrical Characteristics: Synchronous timing, positive edge trigger, 24 MHz count rate capability
• Supply Voltage Range: 2 V to 6 V operation
• Operating Temperature Range: -55°C to 125°C
• Package Specification: 16-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm width)
• Compliance Standards: ROHS3 compliance, REACH unaffected status, EAR99 classification

The CD74HC163M96 meets all these criteria and serves as a direct functional equivalent. The primary distinction between these parts is packaging format: the main part is supplied in Tube packaging, while the substitute is supplied in Tape & Reel (TR) format. Both parts share identical electrical performance, thermal characteristics, and physical package dimensions.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC163M96 is the direct equivalent substitute for the CD74HC163M. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications, thermal performance, and physical package dimensions. The CD74HC163M96 is currently in Active product status with higher inventory availability (4938 Pcs), compared to the Last Time Buy status of the CD74HC163M (1357 Pcs).

The only functional difference between these parts is the packaging format: Tube versus Tape & Reel. This distinction affects handling, storage, and automated assembly processes but does not impact electrical performance or circuit functionality. Selection between these parts should be based on production requirements and assembly equipment compatibility.

Both parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC163M96 be used as a direct replacement for the CD74HC163M?

A: Yes. The CD74HC163M96 is electrically and functionally identical to the CD74HC163M. Both parts share the same 4-bit binary counter logic, 24 MHz count rate, 2 V to 6 V supply voltage range, -55°C to 125°C operating temperature, and 16-SOIC package dimensions. The parts are interchangeable from a circuit design perspective.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in plastic tubes suitable for manual handling and small-volume assembly. Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly equipment. Both formats contain identical components with no electrical differences.

Q: Why is the CD74HC163M marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments is discontinuing this part number. Existing inventory will be sold until depletion, after which the part will no longer be available. The CD74HC163M96 (Tape & Reel format) remains in Active status and is the recommended alternative for new designs and ongoing production.

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

A: No. Both the CD74HC163M and CD74HC163M96 maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. There are no regulatory or compliance differences between these parts.

Q: Which part should I select for new production?

A: The CD74HC163M96 is recommended for new production due to its Active product status and higher inventory availability. If your assembly process requires Tube packaging, the CD74HC163M remains available while supplies last, but planning for transition to the CD74HC163M96 is advised.
