Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26LS32ACD is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package type: 16-SOIC form factor (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Receiver configuration: 0/4 (4 receivers, 0 drivers)
• Protocol support: RS422 minimum requirement
• Operating temperature range: Must encompass or match 0°C ~ 70°C
• Supply voltage: Must be compatible with 4.75V ~ 5.25V or provide overlap

Substitution Logic: Parts are grouped as direct substitutes when they maintain identical package geometry, receiver count, and protocol support. Voltage supply differences and extended temperature ranges represent design trade-offs that may require circuit evaluation but do not preclude substitution at the component level. Receiver hysteresis and data rate variations are acceptable within the same protocol family when package and pin configuration remain constant.

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Direct Replacement (Identical Specifications): AM26LS32ACDR is the primary substitute for AM26LS32ACD. Both parts are manufactured by Texas Instruments with identical electrical specifications, operating temperature range, and supply voltage. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tube). This part maintains Active product status, ensuring continued availability and supply chain support.

Tier 2 - Functional Equivalents (Different Voltage/Temperature): MAX3096CSE+, MAX3096CSE+T, MAX3096ESE+, and MAX3096ESE+T are manufactured by Analog Devices Inc./Maxim Integrated. These parts share the 16-SOIC package, 0/4 receiver configuration, and RS422 protocol support. All MAX3096 variants are Active products with higher inventory levels. Substitution requires circuit evaluation due to reduced supply voltage (3V ~ 3.6V versus 4.75V ~ 5.25V). MAX3096ESE+ and MAX3096ESE+T offer extended operating temperature range (-40°C ~ 85°C), suitable for industrial applications.

Tier 3 - Protocol-Extended Equivalent (Last Time Buy Status): SP26LV432CN-L, manufactured by MaxLinear Inc., shares the 16-SOIC package and 0/4 receiver configuration. This part supports RS422 and RS485 protocols with higher data rate capability (50Mbps). Supply voltage is fixed at 3.3V, requiring circuit redesign. Product status is Last Time Buy with limited inventory (2,833 pcs), making it unsuitable for long-term supply assurance.

Compliance & Certification: All listed parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001. Moisture Sensitivity Level is 1 (Unlimited) for all parts except SP26LV432CN-L (MSL 2, 1 Year).

Frequently Asked Questions (FAQ)

Q: Can AM26LS32ACDR directly replace AM26LS32ACD without circuit modification? A: Yes. AM26LS32ACDR is electrically and functionally identical to AM26LS32ACD. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tube). No circuit modification is required.

Q: What is the primary reason to substitute AM26LS32ACD? A: AM26LS32ACD is designated Last Time Buy, indicating discontinued production. AM26LS32ACDR provides identical functionality with Active product status and higher inventory availability (38,682 pcs).

Q: Can MAX3096 series parts replace AM26LS32ACD in existing designs? A: MAX3096 parts are functionally equivalent but operate at reduced supply voltage (3V ~ 3.6V versus 4.75V ~ 5.25V). Circuit evaluation is required to confirm compatibility with existing power supply architecture. Pin configuration and package remain identical.

Q: What is the difference between MAX3096CSE+ and MAX3096ESE+ variants? A: Both share identical electrical specifications and data rate (10Mbps). MAX3096ESE+ offers extended operating temperature range (-40°C ~ 85°C) compared to MAX3096CSE+ (0°C ~ 70°C). Selection depends on application temperature requirements.

Q: Why is SP26LV432CN-L not recommended as a primary substitute? A: SP26LV432CN-L carries Last Time Buy status with limited inventory (2,833 pcs), providing no long-term supply assurance. Additionally, fixed 3.3V supply voltage requires circuit redesign compared to the original 4.75V ~ 5.25V specification.

Q: Are all substitute parts available in both Tube and Cut Tape packaging? A: No. AM26LS32ACDR, MAX3096CSE+T, and MAX3096ESE+T are available in Cut Tape (CT) & Digi-Reel® format. MAX3096CSE+, MAX3096ESE+, and SP26LV432CN-L are available in Tube packaging only.

Q: What is the receiver hysteresis difference between AM26LS32ACD and MAX3096 parts? A: AM26LS32ACD specifies 50 mV receiver hysteresis, while MAX3096 variants specify 45 mV. This 5 mV difference is within typical design margins for RS422 applications and does not preclude substitution.

Q: Do all substitute parts maintain ROHS3 compliance? A: Yes. All listed substitute parts are ROHS3 Compliant with identical REACH and ECCN classifications as the original AM26LS32ACD.
