SN75107ADR Equivalent & Substitute Parts

Part Overview

The SN75107ADR is a 0/2 Receiver interface IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This component is classified as Obsolete, making identification of suitable alternatives essential for ongoing design support and production continuity. The part operates within a ±4.75V to 5.25V supply voltage range and is rated for 0°C to 70°C operating temperatures. Due to its obsolete status, equivalent or substitute components must be evaluated based on functional capability and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75107ADR is based on the following critical parameters:

Functional Compatibility: The SN75107ADR is a receiver-only device (0/2 configuration). Substitute components must provide equivalent receiver functionality to maintain circuit operation.

Electrical Parameters: Supply voltage range, operating temperature range, and receiver hysteresis characteristics determine functional equivalence. The substitute must operate within compatible voltage and temperature specifications.

Package and Mounting: Surface mount technology is required. Package footprint differences must be evaluated for PCB layout compatibility.

Compliance and Certification: RoHS3 compliance and MSL rating ensure manufacturing and environmental compatibility with current production standards.

The SN65C1167ENSR is identified as a manufacturer-recommended substitute based on its receiver capability (2/2 transceiver configuration includes 2 receivers), compatible supply voltage range, surface mount packaging, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SN65C1167ENSR is the manufacturer-recommended substitute for the obsolete SN75107ADR. Both components are manufactured by Texas Instruments and maintain ROHS3 compliance with MSL 1 ratings, ensuring compatibility with current manufacturing and environmental standards.

The SN65C1167ENSR provides extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and active product status, supporting long-term design continuity. The supply voltage ranges are compatible, with the substitute offering slightly wider tolerance (4.5V to 5.5V).

Package differences exist: the SN65C1167ENSR uses a 16-SOIC package (5.30mm width) compared to the 14-SOIC package (3.90mm width) of the original part. PCB layout modifications are required to accommodate the larger package footprint.

Frequently Asked Questions (FAQ)

Q: Can the SN65C1167ENSR directly replace the SN75107ADR without circuit modifications?

A: The SN65C1167ENSR provides receiver functionality compatible with the SN75107ADR. However, the package size differs (16-SOIC versus 14-SOIC), requiring PCB layout changes. Pin configuration must be verified against application schematics before implementation.

Q: What is the primary reason for substitution?

A: The SN75107ADR is classified as Obsolete. The SN65C1167ENSR is an Active product from the same manufacturer, ensuring ongoing availability and manufacturing support.

Q: Are there compliance differences between the two parts?

A: Both components are ROHS3 compliant with MSL 1 ratings. No compliance barriers exist for substitution.

Q: How do the operating temperature ranges compare?

A: The SN75107ADR operates from 0°C to 70°C. The SN65C1167ENSR extends this range to -40°C to 85°C, providing broader environmental compatibility.

Q: What supply voltage considerations apply?

A: The SN75107ADR requires ±4.75V to 5.25V. The SN65C1167ENSR operates from 4.5V to 5.5V. Both ranges are compatible with standard 5V supply systems.
