Substitute Part Grouping Explanation

Substitute parts for the SN74HC253NG4 are qualified based on matching the following critical parameters:

• Circuit configuration: 2 x 4:1 multiplexer topology
• Package type: 16-DIP (0.300", 7.62mm)
• Mounting method: Through Hole
• Voltage supply range: 2V ~ 6V
• Output current specifications: 7.8mA high and low
• Operating temperature range: -40°C ~ 85°C
• Series compatibility: 74HC logic family
• Regulatory compliance: ROHS3 and REACH standards

The SN74HC253N serves as the manufacturer-recommended direct substitute with identical specifications and active product status. The SN74HC153AN and SN74HC153N are parametric equivalents sharing all electrical and mechanical characteristics while differing only in base product designation (74HC153 versus 74HC253).

Parameter Comparison

Engineering Selection Recommendations

SN74HC253N is the primary substitute for the SN74HC253NG4. This part maintains active product status with Texas Instruments and carries identical electrical and mechanical specifications. The SN74HC253N is available in higher inventory quantities (3104 units) compared to the original part, ensuring supply chain continuity.

SN74HC153AN and SN74HC153N are parametric equivalents that satisfy all functional and electrical requirements. Both parts are active products with robust inventory availability (2052 and 5044 units respectively). These alternatives differ only in base product designation but deliver equivalent performance in 2 x 4:1 multiplexer applications.

All substitute options maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current manufacturing standards. Selection between these alternatives depends on packaging preference (Tube) and inventory availability at the point of procurement.

Frequently Asked Questions (FAQ)

Q: Can SN74HC153AN or SN74HC153N be used as direct replacements for SN74HC253NG4?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, output current ratings, voltage supply ranges, and operating temperature specifications. The 16-DIP package and through-hole mounting are identical across all parts.

Q: What is the difference between SN74HC253N and SN74HC153AN/SN74HC153N?

A: The primary difference is the base product number designation (74HC253 versus 74HC153). All three parts deliver identical 2 x 4:1 multiplexer functionality with matching electrical and mechanical parameters. The substitution is based on parametric equivalence rather than direct part number matching.

Q: Is the packaging different between these substitute parts?

A: The SN74HC253NG4 uses -NG4 packaging designation. The substitute parts (SN74HC253N, SN74HC153AN, SN74HC153N) use Tube packaging. All maintain the same 16-DIP (0.300", 7.62mm) physical form factor and through-hole mounting configuration, ensuring PCB compatibility.

Q: Are all substitute parts compliant with current regulatory standards?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Which substitute part should I select for new designs?

A: SN74HC253N is the manufacturer-recommended substitute with active product status and the closest designation match to the original part. SN74HC153AN and SN74HC153N are equally valid alternatives if inventory or procurement preferences favor these options.
