Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN75468NG4 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Transistor configuration: 7 NPN Darlington array
• Maximum collector current: 500mA
• Collector-emitter breakdown voltage: 100V
• Saturation voltage characteristics: 1.6V @ 500µA, 350mA
• Operating temperature range: 150°C (TJ)

Mechanical & Compliance Requirements:

• Package type: 16-DIP (0.300", 7.62mm) Through Hole
• Automotive grade qualification: AEC-Q100
• RoHS3 compliance
• REACH unaffected status

Substitute parts must match all electrical parameters and maintain identical package specifications and automotive qualifications to ensure direct functional and physical compatibility without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The SN75468N serves as the direct equivalent substitute for the discontinued SN75468NG4. Both components are manufactured by Texas Instruments and share identical electrical specifications, package configuration, and automotive-grade qualifications.

Selection Basis:

The SN75468N maintains full compatibility with the SN75468NG4 across all critical parameters: 7 NPN Darlington transistor array, 500mA maximum collector current, 100V collector-emitter breakdown voltage, and 1.6V saturation voltage at specified bias conditions. Both devices are qualified to AEC-Q100 automotive standards and comply with ROHS3 and REACH requirements.

The primary distinction is product status: the SN75468NG4 is discontinued, while the SN75468N remains in active production with higher inventory availability (3068 Pcs versus 1012 Pcs). The SN75468N is supplied in Tube packaging, whereas the SN75468NG4 packaging specification is not provided. Both utilize the 16-PDIP package format for Through Hole mounting.

For new designs and ongoing production requiring this transistor array, the SN75468N is the appropriate selection due to active availability and identical functional performance.
