Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75182DR is determined by the following critical parameters:

Supply Voltage Compatibility: The substitute must operate within the 4.5V ~ 5.5V range to ensure direct replacement capability in existing circuits.

Receiver/Transceiver Functionality: The SN75182DR provides 0/2 receiver configuration. Substitute components must provide equivalent or enhanced receiver capability to maintain signal reception functionality.

Interface Category: Both the main part and substitute must belong to the Interface category to ensure functional equivalence in signal conditioning and transmission applications.

Surface Mount Packaging: The substitute must use surface mount technology to maintain PCB assembly compatibility.

Compliance Standards: RoHS3 compliance and REACH unaffected status must be maintained for regulatory and supply chain continuity.

The SN65C1167ENSR qualifies as a manufacturer-recommended substitute based on these parameters, despite differences in package size and enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

The SN65C1167ENSR is designated as the manufacturer-recommended substitute for the obsolete SN75182DR. Selection of this alternative is supported by:

Product Status: The SN65C1167ENSR maintains Active product status, ensuring continued availability and supply chain support compared to the Obsolete SN75182DR.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent deployment.

Supply Voltage Alignment: Identical 4.5V ~ 5.5V supply voltage specifications enable direct electrical integration without additional power conditioning.

Enhanced Operating Range: The SN65C1167ENSR provides extended operating temperature range (-40°C ~ 85°C) compared to the SN75182DR (0°C ~ 70°C), supporting broader application environments.

Functional Enhancement: The transition from Receiver (0/2) to Transceiver (2/2) configuration provides bidirectional communication capability, supporting expanded system functionality.

Frequently Asked Questions (FAQ)

Q: Can the SN65C1167ENSR directly replace the SN75182DR without circuit modifications?

A: The SN65C1167ENSR provides compatible supply voltage (4.5V ~ 5.5V) and surface mount technology. However, the package size differs (16-SOIC versus 14-SOIC), requiring PCB layout adjustment. The transceiver functionality is compatible with receiver-only applications.

Q: What is the primary reason for substitution?

A: The SN75182DR is classified as Obsolete. The SN65C1167ENSR is the manufacturer-recommended active alternative, ensuring long-term component availability and supply continuity.

Q: Are there compliance differences between the two parts?

A: Both components maintain ROHS3 compliance and REACH unaffected status. No compliance degradation occurs with substitution.

Q: How does the package size difference affect selection?

A: The SN65C1167ENSR uses 16-SOIC (5.30mm width) compared to the SN75182DR 14-SOIC (3.90mm width). PCB footprint and layout spacing must accommodate the larger package dimensions.

Q: What is the functional difference between Receiver and Transceiver configurations?

A: The SN75182DR provides receive-only functionality (0/2). The SN65C1167ENSR provides full duplex transceiver capability (2/2), enabling both transmission and reception on independent channels.

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

A: The SN65C1167ENSR operating range (-40°C ~ 85°C) encompasses the SN75182DR range (0°C ~ 70°C). This extended specification provides enhanced environmental flexibility without compatibility issues.
