SN75183NG4 Equivalent & Substitute Parts

Part Overview

The SN75183NG4 is a 2/0 Driver interface IC manufactured by Texas Instruments in a 14-PDIP through-hole package. This component is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates within a 4.75V to 5.25V supply voltage range and is rated for 0°C to 70°C operating temperatures. Identifying compatible substitutes ensures system functionality when the original part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN75183NG4 is determined by the following critical parameters:

Primary Substitution Criteria:

• Driver/Receiver configuration (2/0 drivers minimum)
• Supply voltage compatibility (4.75V ~ 5.25V range or broader)
• Operating temperature range (0°C ~ 70°C minimum coverage)
• Package type (through-hole or surface mount, depending on application requirements)
• RoHS and REACH compliance status

Substitution Logic:

The SN75183N provides direct equivalence as a through-hole 14-PDIP package variant with identical electrical specifications. This part maintains the same 2/0 driver configuration, voltage range, and temperature rating, differing only in product status (Obsolete vs. Discontinued).

The AM26C31IDR represents a functional upgrade substitute with enhanced specifications. While it increases the driver/receiver count to 4/0 and expands the supply voltage range to 4.5V ~ 5.5V with extended temperature coverage (-40°C ~ 85°C), it requires surface-mount integration due to its 16-SOIC package. This substitute is suitable for applications where PCB redesign for surface-mount technology is feasible and the enhanced performance envelope is acceptable.

Parameter Comparison

Engineering Selection Recommendations

SN75183N (Equivalent Substitute): Select this part for direct replacement in existing through-hole PCB designs. The SN75183N maintains identical electrical specifications and package footprint compatibility with the SN75183NG4. Although marked as Obsolete, it provides the most straightforward substitution path without requiring circuit board redesign. Both parts are ROHS3 compliant and REACH unaffected, ensuring regulatory compliance continuity.

AM26C31IDR (Upgrade Substitute): Select this part when PCB redesign for surface-mount technology is acceptable and extended operating temperature range (-40°C ~ 85°C) or expanded supply voltage tolerance (4.5V ~ 5.5V) is beneficial. The increased driver/receiver count (4/0) provides additional functionality beyond the original 2/0 configuration. This part carries Active product status, ensuring long-term availability and supply chain stability. ROHS3 compliance and REACH unaffected status maintain regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the AM26C31IDR directly replace the SN75183NG4 without PCB modification?

A: No. The AM26C31IDR uses a 16-SOIC surface-mount package, while the SN75183NG4 uses a 14-DIP through-hole package. PCB redesign is required for footprint compatibility. The SN75183N is the direct through-hole equivalent.

Q: What is the key difference between SN75183N and AM26C31IDR?

A: The SN75183N maintains identical 2/0 driver configuration and through-hole 14-DIP packaging. The AM26C31IDR increases to 4/0 drivers, expands voltage and temperature ranges, and requires surface-mount 16-SOIC packaging. Choose SN75183N for drop-in replacement; choose AM26C31IDR for enhanced specifications with redesign.

Q: Are all three parts ROHS3 compliant?

A: Yes. The SN75183NG4, SN75183N, and AM26C31IDR are all ROHS3 compliant and REACH unaffected, ensuring regulatory compliance across all substitution options.

Q: Why is the SN75183NG4 discontinued while AM26C31IDR is active?

A: Product lifecycle management determines availability. The AM26C31IDR represents an active product line with ongoing manufacturing and supply chain support, making it a more reliable long-term sourcing option despite requiring design integration changes.

Q: Can I use AM26C31IDR in applications requiring only 2/0 driver configuration?

A: Yes. The AM26C31IDR provides 4/0 drivers, which exceeds the 2/0 requirement. The additional drivers remain available for future expansion or can be left unused if not required by the application.
