Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74S124NG4 is determined by strict equivalence across the following critical parameters:

• Dual VCO functional type and architecture
• Frequency range: 1Hz ~ 60MHz
• Supply voltage specification: 4.75V ~ 5.25V
• Supply current: 105 mA
• Operating temperature range: 0°C ~ 70°C
• Package configuration: 16-DIP (0.300", 7.62mm)
• Through-hole mounting compatibility
• Pin-for-pin electrical compatibility

The SN74S124N qualifies as a direct manufacturer-recommended substitute, maintaining identical electrical specifications and package footprint while differing only in product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The SN74S124N is the manufacturer-recommended substitute for the discontinued SN74S124NG4. Both parts maintain identical electrical and mechanical specifications, ensuring direct compatibility in existing circuit designs. The SN74S124N carries active product status with significantly higher inventory availability (15,100 pieces in stock versus 835 pieces for the original part), supporting continued production requirements.

Both parts comply with ROHS3 standards and REACH regulations, maintaining equivalent environmental compliance profiles. The SN74S124N is supplied in tube packaging, which may differ from the original part's packaging format but does not affect functional performance or pin compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SN74S124N be used as a direct replacement for the SN74S124NG4?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, frequency range, supply voltage, current consumption, operating temperature range, and 16-DIP package configuration. Pin-for-pin compatibility is maintained.

Q: What is the primary reason for substitution?

A: The SN74S124NG4 is discontinued at DiGi Electronics. The SN74S124N provides equivalent functionality with active product status and higher inventory availability.

Q: Are there differences in packaging between these parts?

A: The SN74S124N is supplied in tube packaging, while the SN74S124NG4 packaging format is not specified in available data. Both use identical 16-DIP through-hole package configuration, ensuring mechanical compatibility on printed circuit boards.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SN74S124NG4 and SN74S124N are ROHS3 compliant and REACH unaffected, maintaining equivalent environmental and regulatory compliance.

Q: What are the critical parameters for substitution verification?

A: Verify frequency range (1Hz ~ 60MHz), supply voltage (4.75V ~ 5.25V), supply current (105 mA), operating temperature (0°C ~ 70°C), and 16-DIP package configuration match your application requirements.
