AM26LS33ACD Equivalent & Substitute Parts

Part Overview

The AM26LS33ACD is a 0/4 Receiver interface IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as Last Time Buy, indicating limited future availability. The AM26LS33ACD operates within a 4.75V to 5.25V supply voltage range and supports operating temperatures from 0°C to 70°C. Finding equivalent and substitute parts is necessary due to the Last Time Buy status, which restricts long-term procurement options and requires identification of compatible alternatives for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26LS33ACD is determined by the following critical parameters: identical package type (16-SOIC surface mount), matching number of drivers/receivers (0/4 configuration), compatible supply voltage range, and surface mount mounting type. The receiver hysteresis specification (50 mV minimum) and RoHS3 compliance are additional compatibility factors.

Substitute parts are grouped into two categories:

Category 1: Direct Texas Instruments Substitutes — Parts that maintain identical electrical specifications and are from the same manufacturer, ensuring maximum compatibility with existing designs.

Category 2: Cross-Manufacturer Alternatives — Parts from other manufacturers that meet the core electrical and mechanical requirements but may have extended operating temperature ranges or different protocol support.

Parameter Comparison

Engineering Selection Recommendations

AM26LS33ACDR is the primary recommended substitute. It is manufactured by Texas Instruments with identical electrical specifications to the AM26LS33ACD, including matching supply voltage (4.75V ~ 5.25V), operating temperature range (0°C ~ 70°C), and receiver hysteresis (50 mV). The primary difference is packaging format (Cut Tape & Digi-Reel versus Tube) and Active product status, ensuring long-term availability. This part is suitable for direct replacement in existing designs.

DS26C32ATM/NOPB and DS26C32ATMX/NOPB are Texas Instruments alternatives with extended operating temperature range (-40°C ~ 85°C) and slightly wider supply voltage tolerance (4.5V ~ 5.5V). These parts support RS422 and RS423 protocols and feature 60 mV receiver hysteresis. The DS26C32ATMX/NOPB variant offers the highest inventory availability (22,854 pcs) and Active product status. These parts are suitable for applications requiring extended temperature performance.

SP26LV432CN-L is a MaxLinear alternative supporting RS422 and RS485 protocols with 50 Mbps data rate capability. This part operates at 3.3V supply voltage, which differs from the AM26LS33ACD's 5V specification. The SP26LV432CN-L is classified as Last Time Buy and carries MSL 2 (1 Year) moisture sensitivity. This part is suitable only for designs with 3.3V supply requirements and should not be used as a direct replacement for 5V applications.

All substitute parts maintain ROHS3 compliance and identical 16-SOIC package geometry, ensuring mechanical compatibility with existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can AM26LS33ACDR be used as a direct replacement for AM26LS33ACD?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, including supply voltage (4.75V ~ 5.25V), operating temperature (0°C ~ 70°C), receiver hysteresis (50 mV), and 16-SOIC package. The only difference is packaging format (Cut Tape & Digi-Reel versus Tube). PCB layout and schematic compatibility is maintained.

Q: What is the difference between DS26C32ATM/NOPB and DS26C32ATMX/NOPB?

A: Both parts are electrically identical with identical specifications. The primary difference is packaging format: DS26C32ATM/NOPB is supplied in Tube packaging, while DS26C32ATMX/NOPB is supplied in Cut Tape & Digi-Reel format. DS26C32ATMX/NOPB has significantly higher inventory availability (22,854 pcs versus 1,312 pcs).

Q: Can SP26LV432CN-L replace AM26LS33ACD in a 5V application?

A: No. The SP26LV432CN-L operates at 3.3V supply voltage, which is incompatible with the AM26LS33ACD's 4.75V ~ 5.25V specification. Using this part in a 5V circuit will result in device malfunction or damage. The SP26LV432CN-L is suitable only for 3.3V designs.

Q: Why do DS26C32 parts have different receiver hysteresis (60 mV) compared to AM26LS33ACD (50 mV)?

A: The receiver hysteresis specification is a distinct electrical characteristic of each device family. The DS26C32 series specifies 60 mV hysteresis, while the AM26LS33 series specifies 50 mV. Both values are within acceptable receiver performance parameters for interface applications. The higher hysteresis value in DS26C32 parts provides increased noise immunity.

Q: What is the significance of Product Status (Active vs. Last Time Buy)?

A: Active status indicates the manufacturer continues production and supports long-term availability. Last Time Buy status indicates the manufacturer will discontinue production, with limited stock available. AM26LS33ACD and SP26LV432CN-L are Last Time Buy parts, making AM26LS33ACDR, DS26C32ATM/NOPB, and DS26C32ATMX/NOPB preferred choices for new designs requiring long-term component availability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (AM26LS33ACDR, DS26C32ATM/NOPB, DS26C32ATMX/NOPB, and SP26LV432CN-L) are ROHS3 compliant, matching the compliance status of the AM26LS33ACD.

Q: What does Moisture Sensitivity Level (MSL) indicate?

A: MSL specifies the maximum time a component can be exposed to moisture before soldering. AM26LS33ACD, AM26LS33ACDR, DS26C32ATM/NOPB, and DS26C32ATMX/NOPB carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. SP26LV432CN-L carries MSL 2 (1 Year), requiring storage in controlled humidity conditions and limiting shelf life to one year after packaging.
