74F163APC Equivalent & Substitute Parts

Part Overview

The 74F163APC is a 4-bit binary counter IC manufactured by onsemi, housed in a 16-DIP package. This component functions as a synchronous, positive-edge-triggered counter with a maximum count rate of 120 MHz and operates within a 4.5V to 5.5V supply voltage range. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74F163APC is determined by strict equivalence across the following critical parameters:

• Logic Function: Binary counter with identical 4-bit configuration
• Trigger Mechanism: Positive edge-triggered operation
• Reset Configuration: Synchronous reset capability
• Electrical Specifications: Supply voltage range 4.5V to 5.5V
• Package Compatibility: 16-DIP through-hole mounting
• Pin Configuration: Identical pinout within the 74F series base product number

The SN74F163AN from Texas Instruments meets all substitution criteria as a direct functional equivalent within the 74F logic family.

Parameter Comparison

Engineering Selection Recommendations

The SN74F163AN serves as the primary substitute for the 74F163APC. Both components share identical functional specifications, electrical parameters, and physical packaging. The SN74F163AN is currently in active production status, ensuring long-term availability and supply chain reliability compared to the obsolete 74F163APC.

The SN74F163AN carries ROHS3 compliance certification, meeting modern environmental and regulatory requirements. Both parts maintain REACH Unaffected status and identical ECCN and HTSUS classifications, confirming regulatory equivalence.

The count rate differential (120 MHz versus 100 MHz) does not affect substitution validity, as the SN74F163AN's 100 MHz specification remains within acceptable operating margins for applications designed for the 74F163APC. Pin-for-pin compatibility and identical logic family membership ensure direct board-level replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the SN74F163AN directly replace the 74F163APC without PCB modifications?

A: Yes. Both components share identical pinout, package dimensions (16-DIP), and electrical specifications. Direct socket substitution is possible without circuit redesign.

Q: What is the significance of the count rate difference (120 MHz vs. 100 MHz)?

A: The 74F163APC specifies 120 MHz maximum count rate, while the SN74F163AN specifies 100 MHz. For applications operating below 100 MHz, this difference is not a limiting factor. Applications requiring operation above 100 MHz should be evaluated against actual system timing requirements.

Q: Why is the 74F163APC classified as obsolete?

A: Obsolete status indicates the manufacturer (onsemi) has discontinued production. The SN74F163AN remains in active production, making it the recommended source for new inventory and ongoing system support.

Q: Are there compliance differences between these parts?

A: The SN74F163AN carries ROHS3 compliance certification. Both parts maintain REACH Unaffected status and identical trade classification codes, confirming regulatory equivalence for most applications.

Q: What packaging options are available for the SN74F163AN?

A: The SN74F163AN is supplied in tube packaging. The 16-DIP package configuration remains consistent with the original 74F163APC specification.
