AM26LS33ACN Equivalent & Substitute Parts

Part Overview

The AM26LS33ACN is a 0/4 Receiver interface IC manufactured by Texas Instruments in a 16-DIP through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The AM26LS33ACN operates within a 4.75V to 5.25V supply voltage range and maintains a 50 mV receiver hysteresis specification across an operating temperature range of 0°C to 70°C. Identifying compatible alternatives ensures design flexibility and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM26LS33ACN is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Number of Drivers/Receivers: 0/4 configuration
• Receiver Hysteresis: 50 mV
• Voltage - Supply: 4.75V ~ 5.25V
• Operating Temperature: 0°C ~ 70°C
• Category: Interface Receiver

Mechanical Compatibility Criteria:

• Package type and pin configuration must support the application's mounting requirements
• Pin count and arrangement must match or be compatible with existing PCB layouts

The AM26LS33ACDR is identified as the manufacturer-recommended substitute. This part maintains identical electrical specifications while offering an alternative surface-mount package option (16-SOIC) and active product status, providing improved long-term availability compared to the obsolete through-hole variant.

Parameter Comparison

Engineering Selection Recommendations

The AM26LS33ACDR is the direct electrical equivalent to the AM26LS33ACN, with identical receiver configuration, hysteresis, and supply voltage specifications. Both parts maintain ROHS3 compliance and are unaffected by REACH regulations.

Key Differentiation:

• The AM26LS33ACN is through-hole mounted and classified as obsolete
• The AM26LS33ACDR is surface-mount and maintains active product status

Selection between these parts depends on PCB assembly requirements. Through-hole designs requiring the AM26LS33ACN footprint cannot directly accept the surface-mount AM26LS33ACDR without PCB redesign. Conversely, new surface-mount designs should utilize the AM26LS33ACDR to ensure long-term component availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the AM26LS33ACDR directly replace the AM26LS33ACN on an existing PCB? A: No. The AM26LS33ACN uses a through-hole 16-DIP package, while the AM26LS33ACDR uses a surface-mount 16-SOIC package. PCB redesign is required to accommodate the different mounting type and footprint.

Q: Are the electrical specifications identical between these parts? A: Yes. Both parts share identical receiver configuration (0/4), receiver hysteresis (50 mV), supply voltage range (4.75V ~ 5.25V), and operating temperature range (0°C ~ 70°C).

Q: Why is the AM26LS33ACN classified as obsolete? A: The AM26LS33ACN is an older through-hole package variant. Texas Instruments has transitioned to surface-mount technology, making the AM26LS33ACDR the active production equivalent.

Q: What is the moisture sensitivity level difference? A: The AM26LS33ACN lists MSL as Not Applicable (through-hole components). The AM26LS33ACDR has MSL 1 (Unlimited), indicating minimal moisture sensitivity for surface-mount storage and handling.

Q: Are both parts RoHS compliant? A: Yes. Both the AM26LS33ACN and AM26LS33ACDR are ROHS3 compliant and REACH unaffected.
