SNJ5407J Equivalent & Substitute Parts

Part Overview

The SNJ5407J is a military-grade, non-inverting buffer IC manufactured by Texas Instruments, designed for applications requiring 6-channel buffering with open collector outputs. This component operates across the 4.5V to 5.5V supply voltage range and is rated for extended military temperature specifications (-55°C to 125°C). The SNJ5407J is classified as an active product with full RoHS3 compliance and is currently in stock with 1574 units available.

Substitute parts are identified when equivalent functional performance can be achieved through components sharing the same logic architecture, output configuration, and core electrical characteristics within acceptable parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SNJ5407J is determined by the following critical parameters:

• Logic Architecture: Buffer, Non-Inverting configuration with 6 elements, 1 bit per element
• Output Configuration: Open Collector output type
• Supply Voltage Range: Compatibility within 4.5V to 5.5V specification
• Output Current Ratings: Current - Output High and Low specifications
• Package Type: 14-pin DIP package format (CDIP or PDIP variants)
• Mounting Technology: Through Hole configuration
• Compliance Status: RoHS3 compliance requirement

The SN7407N qualifies as a substitute based on matching logic type, element count, bit configuration, output type, and package footprint. Voltage and temperature operating ranges differ and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the SNJ5407J and SN7407N are active products with ROHS3 compliance certification. Selection between these components must account for the following parameter differences:

The SNJ5407J operates across a wider supply voltage range (4.5V to 5.5V) compared to the SN7407N (4.75V to 5.25V). The SNJ5407J supports extended military-grade temperature operation (-55°C to 125°C) while the SN7407N is limited to commercial temperature range (0°C to 70°C). Output current specifications differ, with the SN7407N rated for 40mA low output current versus the SNJ5407J's 30mA specification.

Component selection must align with the specific voltage supply tolerance, operating temperature requirements, and output current demands of the target application.

Frequently Asked Questions (FAQ)

Q: Can the SN7407N directly replace the SNJ5407J in all applications?

A: Direct replacement is possible only when the application operates within the SN7407N's voltage range (4.75V to 5.25V) and temperature range (0°C to 70°C). Applications requiring the extended military temperature range or lower voltage tolerance of the SNJ5407J require the original part.

Q: What is the difference between CDIP and PDIP packaging?

A: Both CDIP (Ceramic DIP) and PDIP (Plastic DIP) are 14-pin DIP packages with identical 0.300" (7.62mm) pitch and pin configurations. The primary difference is the substrate material. CDIP uses ceramic while PDIP uses plastic. Both are through-hole mounted and mechanically compatible.

Q: Are there any compliance differences between these parts?

A: Both the SNJ5407J and SN7407N are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution from a regulatory standpoint.

Q: What output current specification should I use for design calculations?

A: Use the output current specification of the component selected for the application. The SNJ5407J is rated for 30mA low output current, while the SN7407N is rated for 40mA. Design margins should account for the specific part's rated current capacity.

Q: Is the SNJ5407J suitable for military applications?

A: The SNJ5407J is designated as a military-grade component with extended temperature range (-55°C to 125°C) and is appropriate for military and aerospace applications requiring these specifications. The SN7407N is a commercial-grade component and does not meet military temperature requirements.
