AM26S10CD Equivalent & Substitute Parts

Part Overview

The AM26S10CD is a 4/4 full duplex transceiver IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as obsolete, indicating it is no longer in active production. The part operates within a supply voltage range of 4.75V to 5.25V and supports operating temperatures from 0°C to 70°C. Due to its obsolete status, identifying functionally compatible substitute components is essential for ongoing system maintenance, redesign efforts, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM26S10CD is determined by the following critical parameters:

• Transceiver Type & Configuration: Both the main part and substitute must function as full duplex transceivers with compatible driver/receiver architecture
• Package Compatibility: Surface mount 16-SOIC packaging is required for PCB layout compatibility
• Supply Voltage Range: The substitute must operate within or encompass the 4.75V to 5.25V supply voltage specification
• Operating Temperature Range: The substitute must support the required thermal operating window
• Compliance & Certification: RoHS3 compliance and MSL rating must be maintained for manufacturing and environmental standards

The SN65C1167ENSR qualifies as a substitute based on shared transceiver functionality, identical surface mount package family (16-SOIC), overlapping supply voltage specifications, and equivalent compliance certifications. While the SN65C1167ENSR operates as a 2/2 configuration (compared to the 4/4 configuration of the AM26S10CD), it maintains full duplex transceiver operation and is manufactured by the same supplier, ensuring design continuity.

Parameter Comparison

Engineering Selection Recommendations

The SN65C1167ENSR is an active production component from Texas Instruments, providing supply continuity for applications requiring transceiver functionality. Both parts maintain ROHS3 compliance and MSL Level 1 ratings, ensuring compatibility with current manufacturing standards and environmental requirements.

The SN65C1167ENSR operates across an extended supply voltage range (4.5V to 5.5V) that encompasses the AM26S10CD specification (4.75V to 5.25V), and supports a broader operating temperature range (-40°C to 85°C) compared to the original part (0°C to 70°C). The substitute is housed in a 16-SOIC package with a larger body width (5.30mm versus 3.90mm), which may require PCB layout evaluation for physical fit.

The primary functional difference is the driver/receiver configuration: the AM26S10CD provides 4/4 channels while the SN65C1167ENSR provides 2/2 channels. Circuit redesign may be necessary if all four channels of the original part are utilized in the application.

Frequently Asked Questions (FAQ)

Q: Can the SN65C1167ENSR directly replace the AM26S10CD without circuit modification?

A: Direct replacement depends on application requirements. Both parts are full duplex transceivers in 16-SOIC packages with compatible supply voltage and temperature operating ranges. However, the SN65C1167ENSR provides 2/2 driver/receiver channels versus the AM26S10CD's 4/4 configuration. If the application uses all four channels, circuit redesign is required. The larger package body width (5.30mm versus 3.90mm) must also be verified for PCB layout compatibility.

Q: What are the key compatibility criteria for transceiver substitution?

A: Transceiver substitution is determined by: transceiver type and duplex mode (full duplex required), surface mount package family (16-SOIC), supply voltage range overlap, operating temperature range adequacy, and compliance certifications (RoHS3, MSL rating). Channel configuration (driver/receiver count) must also be evaluated against application requirements.

Q: Why is the SN65C1167ENSR recommended despite having fewer channels?

A: The SN65C1167ENSR is an active production component from the same manufacturer, ensuring long-term supply availability. It maintains all critical compliance and environmental specifications of the obsolete AM26S10CD while offering an extended operating temperature range. The reduced channel count requires application-level assessment but does not affect the core transceiver functionality.

Q: Are there package considerations when substituting the AM26S10CD?

A: Yes. The AM26S10CD uses a 16-SOIC package with 3.90mm body width, while the SN65C1167ENSR uses a 16-SOIC package with 5.30mm body width. PCB layout and component placement must be verified to accommodate the larger package footprint. Both parts use identical pin counts and surface mount technology.

Q: Do both parts meet current manufacturing and environmental standards?

A: Yes. Both the AM26S10CD and SN65C1167ENSR are ROHS3 compliant and carry MSL Level 1 (Unlimited) ratings, meeting current manufacturing standards for lead-free assembly and moisture sensitivity requirements.
