SN75207BN Equivalent & Substitute Parts

Part Overview

The SN75207BN is a 0/2 Receiver interface IC manufactured by Texas Instruments in a 14-PDIP package. This component is classified as obsolete, making equivalent or substitute parts necessary for new designs and ongoing production requirements. The SN75207BN operates within a supply voltage range of 4.75V to 5.25V and is designed for through-hole mounting applications. Identifying compatible alternatives ensures design continuity and component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75207BN is based on the following critical parameters:

Functional Compatibility: The substitute part must provide receiver functionality with compatible driver/receiver configuration and protocol support.

Electrical Parameters: Supply voltage range, receiver hysteresis, and operating temperature must support the application requirements of the original design.

Compliance & Certification: Both parts must maintain ROHS3 compliance and REACH unaffected status to ensure regulatory alignment.

Package Consideration: While the SN75207BN uses through-hole mounting (14-DIP), substitutes may employ surface-mount technology (16-SOIC) if the PCB design accommodates the alternative package type.

The SN65C1167ENSR qualifies as a substitute based on shared manufacturer origin (Texas Instruments), interface category classification, and equivalent compliance certifications. However, functional differences exist in driver/receiver configuration and protocol support, requiring design-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SN75207BN is obsolete, while the SN65C1167ENSR maintains active product status with current manufacturing support and availability (9508 pcs in stock versus 5600 pcs for the obsolete part).

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory requirements are met in either selection.

Functional Differences: The SN65C1167ENSR provides transceiver functionality (2/2 drivers/receivers) compared to the receiver-only configuration (0/2) of the SN75207BN. This represents an enhancement in capability rather than a direct functional replacement.

Package Transition: Selection of the SN65C1167ENSR requires PCB redesign to accommodate the 16-SOIC surface-mount package, as the original SN75207BN uses 14-DIP through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can the SN65C1167ENSR directly replace the SN75207BN without PCB modification?

A: No. The SN65C1167ENSR uses 16-SOIC surface-mount packaging, while the SN75207BN uses 14-DIP through-hole packaging. PCB redesign is required for physical integration.

Q: What are the key electrical differences between these parts?

A: The SN65C1167ENSR operates with a wider supply voltage range (4.5V ~ 5.5V versus 4.75V ~ 5.25V), lower receiver hysteresis (60 mV versus 500 mV), and extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C). The SN65C1167ENSR also includes RS422 and RS485 protocol support.

Q: Why does the SN65C1167ENSR have different driver/receiver counts?

A: The SN75207BN is a receiver-only device (0/2), while the SN65C1167ENSR is a full-duplex transceiver (2/2). This represents a functional enhancement, not a limitation.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the SN75207BN and SN65C1167ENSR maintain ROHS3 compliance and REACH unaffected status.

Q: Which part should be selected for new designs?

A: The SN65C1167ENSR is the appropriate choice for new designs due to its active product status, extended operating temperature range, and current manufacturing availability. The SN75207BN should only be used for legacy system maintenance where existing PCB designs cannot be modified.
