74FCT162H501CTPACT Equivalent & Substitute Parts

Part Overview

The 74FCT162H501CTPACT is an 18-bit universal bus transceiver manufactured by Texas Instruments in a 56-TSSOP surface mount package. This component is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The part operates across a temperature range of -40°C to 85°C with output drive capabilities of 24mA for both high and low states. Due to its obsolete status, sourcing active alternatives with compatible electrical and mechanical specifications is essential for design continuity.

• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying equivalent regulatory requirements
• Product Availability: The SN74ALVCH16501DGGR maintains active product status with established supply channels, addressing the obsolescence of the original part
• Packaging Format: The substitute is available in Tape & Reel (TR) format, supporting production volume requirements

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVCH16501DGGR be used as a direct replacement for the 74FCT162H501CTPACT?

A: Yes. Both parts share identical package dimensions (56-TFSOP), output drive capabilities (24mA), operating temperature range (-40°C to 85°C), and 18-bit transceiver configuration. The substitute is pin-compatible and functionally equivalent.

Q: What is the primary difference between these two parts?

A: The 74FCT162H501CTPACT is obsolete, while the SN74ALVCH16501DGGR maintains active product status. The substitute specifies a supply voltage range of 1.65V to 3.6V, whereas the original part does not provide this specification in the available data.

Q: Are there any package or mounting considerations when switching to the SN74ALVCH16501DGGR?

A: No. Both parts use surface mount technology with the identical 56-TFSOP package. PCB footprints, solder reflow profiles, and assembly processes remain unchanged.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the 74FCT162H501CTPACT and SN74ALVCH16501DGGR are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings and REACH unaffected status.

Q: What packaging formats are available for the substitute part?

A: The SN74ALVCH16501DGGR is supplied in Tape & Reel (TR) format, suitable for automated assembly and production environments.
