SN75107AD Equivalent & Substitute Parts

Part Overview

The SN75107AD 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 system support and new design implementations. The receiver operates within a ±4.75V to 5.25V supply voltage range and supports industrial temperature applications from 0°C to 70°C. Due to its obsolete status, equivalent parts with compatible electrical and mechanical characteristics are required for procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75107AD is determined by the following critical parameters:

Electrical Compatibility:

• Supply voltage range must accommodate or exceed the original ±4.75V to 5.25V specification
• Receiver functionality must be maintained or enhanced through transceiver capability
• Operating temperature range should support or exceed 0°C to 70°C

Mechanical Compatibility:

• Surface mount packaging is required
• Package footprint must be compatible with existing PCB layouts or acceptable for redesign

Compliance & Status:

• RoHS3 compliance must be maintained
• MSL rating of 1 (Unlimited) ensures handling compatibility
• Active product status is preferred for long-term availability

The SN65C1167ENSR qualifies as a substitute by providing enhanced receiver/driver capability (2/2 Transceiver) with superior electrical specifications, broader operating temperature range (-40°C to 85°C), and active product status, while maintaining RoHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

The SN65C1167ENSR is the manufacturer-recommended substitute for the obsolete SN75107AD. Selection of this alternative is supported by the following engineering criteria:

Product Availability: The SN75107AD is obsolete with no ongoing manufacturing. The SN65C1167ENSR maintains active product status with established supply chains.

Compliance Continuity: Both components maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and handling requirements are preserved.

Electrical Enhancement: The substitute provides expanded supply voltage tolerance (4.5V to 5.5V versus ±4.75V to 5.25V) and extended operating temperature range (-40°C to 85°C versus 0°C to 70°C), supporting broader application environments.

Functional Upgrade: The SN65C1167ENSR provides 2/2 transceiver functionality with RS422/RS485 protocol support, compared to the original 0/2 receiver configuration. This represents a functional enhancement suitable for bidirectional communication requirements.

Package Consideration: The substitute uses a 16-SOIC package (5.30mm width) versus the original 14-SOIC package (3.90mm width). PCB layout modification is required to accommodate the larger footprint.

Frequently Asked Questions (FAQ)

Q: Can the SN65C1167ENSR directly replace the SN75107AD without circuit modifications?

A: The SN65C1167ENSR provides compatible receiver functionality but requires PCB layout changes due to package size difference (16-SOIC versus 14-SOIC). Pin configuration differences must be evaluated against the original circuit design.

Q: What is the primary reason for substitution?

A: The SN75107AD is obsolete. The SN65C1167ENSR is the manufacturer-recommended active alternative that maintains electrical compliance and provides enhanced transceiver capability.

Q: Are there supply voltage compatibility concerns?

A: The SN65C1167ENSR supply voltage range (4.5V to 5.5V) overlaps with and exceeds the SN75107AD specification (±4.75V to 5.25V), ensuring electrical compatibility in standard 5V systems.

Q: Does the substitute support the same operating temperature range?

A: The SN65C1167ENSR operating range (-40°C to 85°C) exceeds the original specification (0°C to 70°C), providing broader environmental support.

Q: Are RoHS and MSL ratings maintained?

A: Both components maintain ROHS3 compliance and MSL 1 (Unlimited) rating, preserving regulatory and handling requirements.

Q: What is the functional difference between receiver and transceiver configurations?

A: The original SN75107AD is a 0/2 receiver (receive-only). The SN65C1167ENSR is a 2/2 transceiver (bidirectional communication), providing both driver and receiver functionality with RS422/RS485 protocol support.
