Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75107BDR is based on the following critical parameters:

• Functional Type: Interface category components with receiver or transceiver capability
• Receiver/Driver Configuration: Minimum 2 receivers to maintain signal reception capability
• Supply Voltage Compatibility: Operating voltage range must overlap or encompass the original specification
• Mounting Type: Surface mount technology for PCB integration compatibility
• Package Compatibility: Physical dimensions and pin count must support board layout requirements
• Compliance Standards: RoHS3 compliance and MSL rating for manufacturing process compatibility

The SN65C1167ENSR qualifies as a substitute based on its receiver capability (2/2 configuration includes 2 receivers), compatible supply voltage range (4.5V ~ 5.5V overlaps the original ±4.75V ~ 5.25V), surface mount packaging, and matching compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SN65C1167ENSR is an active product with extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and broader supply voltage tolerance (4.5V to 5.5V). Both components maintain ROHS3 compliance and MSL Level 1 ratings, ensuring compatibility with standard manufacturing processes.

The primary design consideration is package footprint change from 14-SOIC to 16-SOIC. The substitute provides additional driver capability (2/2 transceiver configuration versus 0/2 receiver), which expands functional scope while maintaining receiver functionality. Supply voltage ranges are compatible within the specified operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the SN65C1167ENSR directly replace the SN75107BDR on existing PCBs?

A: Direct PCB replacement requires layout modification due to package size difference (14-SOIC versus 16-SOIC). Pin count increases from 14 to 16, necessitating footprint redesign and potential routing adjustments.

Q: What are the key electrical compatibility factors?

A: Supply voltage ranges overlap (4.5V to 5.5V for the substitute encompasses the original ±4.75V to 5.25V specification). Both components operate as interface receivers. The substitute adds driver capability without compromising receiver functionality.

Q: Are there compliance or manufacturing process concerns?

A: Both components are ROHS3 compliant with MSL Level 1 ratings. Manufacturing process compatibility is maintained. The substitute's active product status ensures ongoing availability and support.

Q: How does the operating temperature range affect selection?

A: The SN65C1167ENSR supports -40°C to 85°C, exceeding the original 0°C to 70°C specification. This provides broader environmental operating capability for applications requiring extended temperature performance.

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

A: The original SN75107BDR is a receiver-only device (0/2). The SN65C1167ENSR is a full transceiver (2/2), providing both driver and receiver capability. Applications requiring only receiver functionality will operate correctly with the transceiver substitute.
