SN74LS07NSR Equivalent & Substitute Parts

Part Overview

The SN74LS07NSR is a Buffer, Non-Inverting logic integrated circuit manufactured by Texas Instruments. This device features 6 elements with 1 bit per element and open collector output configuration, operating within the 4.75V to 5.25V supply voltage range. The component is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where component availability or packaging requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LS07NSR is determined by strict alignment of the following critical parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 6
• Number of Bits per Element: 1
• Output Type: Open Collector
• Current - Output High, Low: -, 40mA
• Voltage - Supply: 4.75V ~ 5.25V
• Operating Temperature: 0°C ~ 70°C (TA)
• Package / Case: 14-SOIC (0.209", 5.30mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The SN7407NSR meets all substitution criteria as a parametric equivalent, differing only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and base product series designation (7400 versus 74LS). These differences do not affect electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SN74LS07NSR and SN7407NSR maintain Active product status with identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and MSL Level 1 (Unlimited). Selection between these parts should be based on packaging and supply chain requirements. The SN74LS07NSR is available in Cut Tape & Digi-Reel® format with 50,400 pieces in stock. The SN7407NSR is available in Tape & Reel format with 3,182 pieces in stock. Both parts are suitable for production environments where compliance and long-term reliability are required.

Frequently Asked Questions (FAQ)

Q: Can the SN7407NSR directly replace the SN74LS07NSR in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output characteristics, and package dimensions. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel), which does not affect circuit performance or PCB assembly compatibility.

Q: What is the significance of the series designation difference (74LS versus 7400)?

A: The series designation reflects the product line classification within Texas Instruments' logic family. Both the 74LS and 7400 series share identical electrical performance for this buffer configuration. The functional and electrical parameters are equivalent.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL Level 1 (Unlimited) designation. They are suitable for the same regulatory and environmental applications.

Q: How does packaging format affect component selection?

A: Packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) impacts supply chain logistics and assembly line handling but does not affect electrical performance or PCB footprint. Selection should be based on procurement volume requirements and existing supply chain infrastructure.

Q: What is the open collector output configuration used for?

A: Open collector output allows multiple devices to be wire-ORed together and enables interfacing with different voltage levels through external pull-up resistors. This configuration is standard for buffer applications requiring flexible output control.
