Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74F258APC are qualified based on the following electrical and mechanical parameters:

• Circuit type and configuration (4 x 2:1 multiplexer)
• Output current specifications (3mA high, 24mA low)
• Supply voltage range (4.5V ~ 5.5V)
• Operating temperature range (0°C ~ 70°C)
• Package type and form factor (16-DIP through-hole)
• Series classification (74F logic family)

The substitute parts SN74F257N and SN74F258N meet all these criteria and are manufactured by Texas Instruments. Both parts maintain identical electrical performance and physical compatibility with the original 74F258APC.

Parameter Comparison

Engineering Selection Recommendations

Both SN74F257N and SN74F258N are active products manufactured by Texas Instruments and are recommended as direct replacements for the obsolete 74F258APC. The Texas Instruments parts carry ROHS3 compliance certification, providing regulatory advantage for new designs. All three parts share identical electrical specifications and 16-DIP package geometry, enabling direct board-level substitution without circuit modification.

Selection between SN74F257N and SN74F258N depends on specific application requirements and availability. Both parts maintain full parametric equivalence to the original 74F258APC and are suitable for production environments requiring long-term component supply assurance.

Frequently Asked Questions (FAQ)

Q: Can SN74F257N and SN74F258N be used interchangeably with 74F258APC?

A: Yes. Both Texas Instruments parts meet all electrical and mechanical parameters of the 74F258APC. Pin configuration, package dimensions, and functional performance are identical across all three parts.

Q: What is the difference between SN74F257N and SN74F258N?

A: Both parts are 4 x 2:1 multiplexers with identical electrical specifications and package form factors. Selection between them depends on design requirements and component availability.

Q: Are there any compliance differences between the original and substitute parts?

A: The Texas Instruments substitutes (SN74F257N and SN74F258N) carry ROHS3 compliance certification, whereas the original 74F258APC does not specify RoHS status. All parts maintain REACH Unaffected status and EAR99 export classification.

Q: Is PCB layout modification required when substituting these parts?

A: No. The 16-DIP package dimensions and pin assignments are identical. Direct board-level substitution is possible without layout changes.

Q: What is the inventory status of substitute parts?

A: SN74F257N has 2200 units in stock and SN74F258N has 1134 units in stock, both available as new original components in tube packaging.
