AM26S10CDR Equivalent & Substitute Parts

Part Overview

The AM26S10CDR is a 4/4 full duplex transceiver IC manufactured by Texas Instruments, housed in a 16-SOIC surface mount package. This component is classified as obsolete, indicating it is no longer in active production. Due to its obsolete status, identifying functionally compatible substitute parts is essential for ongoing system maintenance, design updates, and procurement continuity. The AM26S10CDR operates within a supply voltage range of 4.75V to 5.25V and is rated for industrial temperature environments from 0°C to 70°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM26S10CDR is determined by the following critical parameters:

Functional Compatibility Criteria:

• Interface category classification (Interface)
• Transceiver type with full duplex capability
• Surface mount packaging technology
• 16-pin SOIC package form factor
• Supply voltage compatibility within acceptable operating ranges
• RoHS3 compliance and MSL rating

Identified Substitute: The SN65C1167ENSR meets the core functional requirements as an active, in-production transceiver from Texas Instruments. While the SN65C1167ENSR operates with 2/2 driver/receiver configuration (compared to the AM26S10CDR's 4/4 configuration), it maintains full duplex operation, surface mount deployment, and 16-SOIC packaging. The substitute supports RS422 and RS485 protocols and operates across an extended temperature range with improved supply voltage tolerance.

Parameter Comparison

Engineering Selection Recommendations

The SN65C1167ENSR is the designated manufacturer-recommended substitute for the obsolete AM26S10CDR. Both components maintain ROHS3 compliance and unlimited moisture sensitivity ratings, ensuring regulatory and environmental consistency.

The substitute provides extended operational advantages: active product status ensures long-term availability and supply chain stability, wider supply voltage tolerance (4.5V to 5.5V versus 4.75V to 5.25V) accommodates broader power supply specifications, and expanded temperature range (-40°C to 85°C versus 0°C to 70°C) supports deployment in more demanding thermal environments.

The primary design consideration is the reduction from 4/4 to 2/2 driver/receiver configuration. Circuit designs requiring four independent driver/receiver pairs must be evaluated for functional compatibility with the two-channel architecture of the substitute. Both components maintain full duplex operation and surface mount deployment in 16-SOIC packages, though physical package dimensions differ slightly (3.90mm versus 5.30mm width).

Frequently Asked Questions (FAQ)

Q: Why is the AM26S10CDR obsolete? A: The AM26S10CDR has reached end-of-life status in Texas Instruments' product portfolio. Obsolete classification indicates the manufacturer no longer produces this component, making substitution necessary for new designs and ongoing system support.

Q: Can the SN65C1167ENSR directly replace the AM26S10CDR in all applications? A: Direct substitution depends on circuit requirements. The SN65C1167ENSR provides 2/2 driver/receiver channels versus the AM26S10CDR's 4/4 configuration. Applications requiring four independent channels must be redesigned or supplemented with additional components.

Q: Are there package compatibility concerns? A: Both components use 16-SOIC surface mount packages. However, physical dimensions differ: the AM26S10CDR measures 3.90mm width while the SN65C1167ENSR measures 5.30mm width. PCB layout and footprint verification is required before implementation.

Q: What are the voltage supply differences? A: The AM26S10CDR operates at 4.75V to 5.25V, while the SN65C1167ENSR operates at 4.5V to 5.5V. The substitute provides wider voltage tolerance, accommodating a broader range of power supply specifications.

Q: Does the substitute support the same protocols? A: The SN65C1167ENSR explicitly supports RS422 and RS485 protocols. The AM26S10CDR protocol specifications are not detailed in the provided data. Protocol compatibility must be verified against specific application requirements.

Q: What is the temperature range difference? A: The AM26S10CDR operates from 0°C to 70°C, while the SN65C1167ENSR operates from -40°C to 85°C. The substitute supports extended temperature operation, suitable for industrial and harsh environment applications.

Q: Are both components RoHS compliant? A: Yes, both the AM26S10CDR and SN65C1167ENSR are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring regulatory consistency and environmental compliance.
