Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74FCT162240CTPACT is determined by strict equivalence across the following critical parameters:

• Logic function: 4-element, 4-bit inverting buffer with 3-state output
• Output drive capability: 24mA high and low current
• Supply voltage range: 4.5V to 5.5V
• Operating temperature range: -40°C to 85°C
• Package type: 48-TFSOP surface mount
• Pin configuration and electrical interface compatibility

The 74FCT162240ATPACT qualifies as a parametric equivalent based on identical electrical specifications and package requirements. Packaging format differences (Cut Tape & Digi-Reel versus standard packaging) do not affect functional or electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 74FCT162240CTPACT and 74FCT162240ATPACT are classified as obsolete products. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Packaging format compatibility with procurement and assembly processes
• Compliance certification status (both are ROHS3 compliant and REACH unaffected)
• Supply chain continuity and long-term sourcing strategy

The 74FCT162240ATPACT currently maintains higher inventory levels (1921 units versus 989 units), which may influence procurement decisions for applications requiring immediate component availability.

Frequently Asked Questions (FAQ)

Q: Can the 74FCT162240ATPACT be used as a direct replacement for the 74FCT162240CTPACT?

A: Yes. Both parts are parametrically equivalent with identical electrical specifications, output drive capabilities, supply voltage range, operating temperature range, and 48-TFSOP package configuration. The difference in packaging format (Cut Tape & Digi-Reel versus standard packaging) does not affect functional compatibility.

Q: What is the significance of the packaging designation difference between CTPACT and ATPACT?

A: The suffix designates the packaging format and supplier reel configuration. CTPACT indicates standard packaging, while ATPACT indicates Cut Tape and Digi-Reel packaging. Both formats contain electrically and mechanically identical components suitable for surface mount assembly.

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

A: No. Both parts carry identical RoHS3 compliance status, REACH unaffected designation, and Moisture Sensitivity Level 1 (unlimited) rating. Compliance certifications are equivalent.

Q: Why is the 74FCT162240 series classified as obsolete?

A: Obsolete status indicates the product is no longer in active production by the manufacturer. This classification necessitates identification of equivalent alternatives for system maintenance and component replenishment.

Q: What parameters must remain constant for a part to qualify as a substitute?

A: Logic function (4-element, 4-bit inverting buffer), output type (3-state), output drive current (24mA), supply voltage range (4.5V to 5.5V), operating temperature range (-40°C to 85°C), and package type (48-TFSOP) must all remain identical for functional substitution.
