Substitute Part Grouping Explanation

Substitution eligibility for the A2982SLW-T is determined by strict equivalence across the following critical parameters:

• Number of Outputs: 8 channels
• Ratio - Input:Output: 1:1 configuration
• Output Configuration: High Side topology
• Output Type: Bipolar switching capability
• Interface: On/Off control logic
• Voltage - Load: 5V ~ 50V operating range
• Current - Output (Max): 500mA per channel
• Input Type: Non-Inverting signal processing
• Package / Case: 20-SOIC form factor
• Operating Temperature: -20°C ~ 85°C range
• Mounting Type: Surface Mount technology

The A2982SLWTR-T qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. Both parts share identical base product number (A2982), functional specifications, and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The A2982SLWTR-T serves as the direct substitute for the A2982SLW-T. Both components maintain identical electrical specifications, mechanical packaging, and regulatory compliance certifications (ROHS3, REACH Unaffected).

The primary distinction lies in product lifecycle status: the A2982SLW-T is classified as Obsolete, while the A2982SLWTR-T is designated Not For New Designs. For existing production lines or legacy system support, the A2982SLWTR-T provides functional continuity with the same performance envelope and package footprint.

Both parts carry ROHS3 compliance and identical MSL ratings, ensuring compatibility with standard surface mount assembly processes and environmental requirements.
