Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74HC163D,652 is determined by the following critical parameters:

• Logic Function: Binary counter, 4-bit, up-counting, positive-edge-triggered, synchronous reset
• Electrical Compatibility: Supply voltage range 2 V to 6 V, count rate capability
• Package Compatibility: 16-SOIC surface mount package (0.154", 3.90mm width) or 16-SO (0.209", 5.30mm width)
• Temperature Range: Operating temperature compatibility
• Compliance: RoHS and REACH status for regulatory requirements

Substitute parts are grouped into two categories:

Upgrade Substitutes: Parts with equivalent or superior electrical performance and active or current product status (CD74HC163M96, CD74HC163MT).

Similar Substitutes: Parts with equivalent functionality but different product status or minor parameter variations (SN74HC163D, SN74HC163DR, SN74HC163DT, SN74HC163NSR).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation for New Designs: CD74HC163M96 (Texas Instruments)

This part is the preferred substitute based on active product status, ROHS3 compliance, and full REACH compliance. It maintains the 16-SOIC (0.154") package footprint and supports the required 2 V to 6 V supply voltage range. The extended operating temperature range (-55°C to 125°C) provides broader environmental coverage than the original part.

Alternative for Active Supply: SN74HC163DR (Texas Instruments)

This part maintains active product status with ROHS3 compliance and REACH compliance. It offers a higher count rate (36 MHz) compared to the CD74HC163M96 (24 MHz), which may be advantageous in timing-critical applications. The operating temperature range is -40°C to 85°C, which is narrower than the original part but suitable for most commercial and industrial applications.

Consideration for Extended Temperature Range: CD74HC163MT (Texas Instruments)

This part provides the same electrical performance as CD74HC163M96 with extended temperature range (-55°C to 125°C) and is listed as Last Time Buy. It is suitable for applications requiring broader temperature coverage but should be procured with awareness of its limited availability status.

Package Variant: SN74HC163NSR (Texas Instruments)

This part is functionally equivalent but uses a 16-SO package (0.209", 5.30mm width) instead of the standard 16-SOIC (0.154", 3.90mm width). This variant is suitable only if PCB layout accommodates the wider package footprint. It maintains active product status and full compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can I use CD74HC163M96 as a direct replacement for 74HC163D,652?

A: Yes. Both parts are 4-bit binary counters with identical logic function, synchronous reset, positive-edge triggering, and 16-SOIC (0.154") package footprint. The supply voltage range (2 V to 6 V) is identical. The CD74HC163M96 has a lower count rate (24 MHz vs. 55 MHz) and extended temperature range (-55°C to 125°C vs. -40°C to 125°C), which are compatible with the original application unless timing margins are critical.

Q: What is the difference between CD74HC163M and CD74HC163M96?

A: CD74HC163M is manufactured by Harris Corporation and is RoHS non-compliant. CD74HC163M96 is manufactured by Texas Instruments and is ROHS3 compliant with full REACH compliance. Both have identical electrical specifications (24 MHz count rate, -55°C to 125°C operating range) and 16-SOIC package. CD74HC163M96 is preferred for new designs due to compliance status.

Q: Why does SN74HC163DR have a higher count rate (36 MHz) than CD74HC163M96 (24 MHz)?

A: Count rate specifications reflect the maximum frequency at which the counter can reliably operate. Both parts perform the same logic function and are electrically compatible at the specified supply voltage and temperature ranges. The higher count rate of SN74HC163DR indicates faster switching capability, which may be beneficial in high-frequency applications but is not required for all designs. Selection should be based on application timing requirements.

Q: Can I use SN74HC163NSR if my PCB is designed for the standard 16-SOIC package?

A: No. SN74HC163NSR uses a 16-SO package with 0.209" width, which is wider than the standard 16-SOIC (0.154") package. PCB footprints are not compatible. Use this variant only if your design specifically accommodates the wider package dimensions.

Q: What is the significance of "Last Time Buy" status?

A: Last Time Buy indicates that the manufacturer has announced end-of-life for the part and will accept orders only until a specified cutoff date. After that date, the part will no longer be available. Parts with this status should be procured with awareness of limited future availability. For long-term supply assurance, prefer parts with Active status such as CD74HC163M96 or SN74HC163DR.

Q: Are all substitute parts RoHS compliant?

A: No. CD74HC163M (Harris Corporation) is RoHS non-compliant. All other substitute parts listed (CD74HC163M96, CD74HC163MT, SN74HC163D, SN74HC163DR, SN74HC163DT, SN74HC163NSR) are ROHS3 compliant. For applications requiring RoHS compliance, use only ROHS3-compliant alternatives.

Q: What packaging options are available for this counter IC?

A: The 74HC163 series is available in two package variants: 16-SOIC (0.154", 3.90mm width) and 16-SO (0.209", 5.30mm width). Most substitute parts use the standard 16-SOIC package. SN74HC163NSR is the only variant listed with the wider 16-SO package. Packaging is specified by the suffix in the part number (D for SOIC, NSR for SO).
