Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75115D is determined by the following critical parameters:

• Package Compatibility: Both main and substitute parts utilize 16-SOIC surface mount packages, ensuring PCB layout compatibility
• Supply Voltage Range: The substitute operates within an extended voltage range (4.5V ~ 5.5V) that encompasses the original specification (4.75V ~ 5.25V)
• Receiver/Transceiver Functionality: The SN65C1167ENSR provides 2/2 transceiver capability, which includes the receiver functionality of the original 0/2 receiver configuration
• Compliance Standards: Both components maintain ROHS3 compliance and MSL Level 1 rating
• Manufacturer Continuity: Both parts are manufactured by Texas Instruments, ensuring design consistency and support

The SN65C1167ENSR is classified as an Active product with current inventory availability, addressing the obsolescence status of the SN75115D.

Parameter Comparison

Engineering Selection Recommendations

The SN65C1167ENSR serves as the manufacturer-recommended substitute for the obsolete SN75115D. Selection of this alternative is supported by:

• Product Status Alignment: The substitute is Active with established supply chain availability, eliminating obsolescence risk
• Regulatory Compliance: Both components maintain identical ROHS3 and REACH compliance status, ensuring regulatory continuity
• Electrical Compatibility: Supply voltage range overlap and extended operating temperature range of the substitute provide operational margin
• Package Form Factor: Both components utilize 16-SOIC surface mount packages with compatible pinout for receiver functionality

The extended operating temperature range (-40°C ~ 85°C) of the SN65C1167ENSR exceeds the original specification, providing enhanced reliability across broader environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the SN65C1167ENSR directly replace the SN75115D on existing PCBs?

A: The SN65C1167ENSR is pin-compatible within the 16-SOIC package family. However, the substitute package width differs (5.30mm versus 3.90mm). PCB layout verification is required to confirm footprint accommodation.

Q: What is the functional difference between a 0/2 Receiver and a 2/2 Transceiver?

A: The SN75115D provides receiver-only functionality (0 drivers, 2 receivers). The SN65C1167ENSR provides full transceiver capability (2 drivers, 2 receivers), offering expanded functionality while maintaining receiver compatibility.

Q: Are there voltage supply considerations when substituting?

A: The SN65C1167ENSR operates across 4.5V ~ 5.5V, which encompasses the original 4.75V ~ 5.25V specification. Existing power supply designs require no modification.

Q: Does the extended operating temperature range of the substitute affect circuit design?

A: The SN65C1167ENSR operates from -40°C ~ 85°C compared to the original 0°C ~ 70°C. This extended range provides additional environmental margin and does not require design changes for applications within the original temperature specification.

Q: What compliance certifications apply to both components?

A: Both the SN75115D and SN65C1167ENSR maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring regulatory continuity in system applications.
