SN75ALS162DWRG4 Equivalent & Substitute Parts

Part Overview

The SN75ALS162DWRG4 is an 8/8 half-duplex transceiver designed for IEEE 488 protocol applications in a 24-SOIC surface mount package. This part is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design requirements and production continuity. The part operates within a 4.75V to 5.25V supply voltage range and supports operating temperatures from 0°C to 70°C.

Substitute Part Grouping Explanation

Substitution for the SN75ALS162DWRG4 is categorized into two distinct groups based on compatibility criteria:

Parametric Equivalent: SN75ALS162DWR matches the core electrical and mechanical specifications of the main part, including identical protocol (IEEE 488), driver/receiver configuration (8/8), duplex mode (half), receiver hysteresis (650 mV), supply voltage range (4.75V ~ 5.25V), operating temperature range (0°C ~ 70°C), and package type (24-SOIC). The primary difference is packaging format (Tape & Reel versus bulk) and product status (Last Time Buy versus Obsolete).

Manufacturer Recommended Substitute: SN65C1167ENSR operates under different electrical parameters, including a different protocol (RS422/RS485), reduced driver/receiver count (2/2), full-duplex operation, lower receiver hysteresis (60 mV), wider supply voltage range (4.5V ~ 5.5V), extended operating temperature range (-40°C ~ 85°C), and smaller package footprint (16-SOIC). This substitute is suitable only when application requirements permit protocol and configuration changes.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: SN75ALS162DWR is the appropriate selection when maintaining identical electrical and functional specifications is required. This part preserves the IEEE 488 protocol, 8/8 driver/receiver configuration, half-duplex operation, and identical package footprint. The part carries Last Time Buy status, indicating limited availability; procurement planning should account for this constraint.

For Protocol-Flexible Applications: SN65C1167ENSR is suitable only when application architecture permits transition from IEEE 488 to RS422/RS485 protocols and when reduced driver/receiver count (2/2) and full-duplex operation align with system requirements. This part offers the advantage of active product status and extended operating temperature range. PCB layout modifications are necessary due to package size reduction (24-SOIC to 16-SOIC).

All substitute options maintain ROHS3 compliance and MSL Level 1 rating, ensuring consistency with environmental and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can SN75ALS162DWR be used as a direct drop-in replacement for SN75ALS162DWRG4?

A: Yes. SN75ALS162DWR is electrically and mechanically equivalent, with identical protocol (IEEE 488), driver/receiver configuration (8/8), duplex mode (half), receiver hysteresis (650 mV), supply voltage (4.75V ~ 5.25V), operating temperature range (0°C ~ 70°C), and package type (24-SOIC). The primary consideration is product status; SN75ALS162DWR is Last Time Buy, requiring supply chain planning.

Q: What are the key differences between SN75ALS162DWRG4 and SN65C1167ENSR?

A: The parts differ in protocol (IEEE 488 versus RS422/RS485), driver/receiver count (8/8 versus 2/2), duplex mode (half versus full), receiver hysteresis (650 mV versus 60 mV), supply voltage range (4.75V ~ 5.25V versus 4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C), and package size (24-SOIC versus 16-SOIC). Substitution requires application-level compatibility assessment.

Q: Is PCB layout modification required when substituting with SN65C1167ENSR?

A: Yes. SN65C1167ENSR uses a 16-SOIC package (0.209", 5.30mm width) compared to the 24-SOIC package (0.295", 7.50mm width) of the main part. Pin count and footprint differ, necessitating PCB redesign and re-layout.

Q: Are all substitute parts RoHS compliant?

A: Yes. Both SN75ALS162DWR and SN65C1167ENSR are ROHS3 compliant and carry MSL Level 1 rating, matching the compliance profile of SN75ALS162DWRG4.

Q: What is the availability status of substitute parts?

A: SN75ALS162DWR carries Last Time Buy status with limited availability. SN65C1167ENSR is classified as Active with higher inventory levels, providing greater long-term availability for new designs.
