Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A2982ELW-T is determined by strict alignment across the following critical parameters:

• Output Configuration & Type: High-side bipolar output with 1:1 input-to-output ratio
• Channel Count: 8 outputs
• Current Rating: 500mA maximum output current
• Load Voltage Range: 5V to 50V operation
• Package: 20-SOIC form factor
• Interface: On/off control with non-inverting input
• Compliance: ROHS3 compliance and MSL 3 rating

The A2982SLWTR-T meets all electrical and mechanical substitution criteria. Differences in product status and operating temperature range are noted but do not affect functional equivalence within specified application parameters.

Parameter Comparison

Engineering Selection Recommendations

The A2982SLWTR-T is a direct functional equivalent to the A2982ELW-T across all specified electrical and mechanical parameters. Both components share identical output configuration, current rating, voltage range, package form factor, and compliance certifications.

The primary distinction is product lifecycle status: the A2982ELW-T is classified as Obsolete, while the A2982SLWTR-T is designated Not For New Designs. For applications requiring component replacement or procurement, the A2982SLWTR-T provides equivalent functionality with improved supply availability (20,840 units in stock versus 836 units).

The operating temperature range difference (-40°C to 85°C versus -20°C to 85°C) should be evaluated against specific application requirements. Applications requiring operation below -20°C must retain the A2982ELW-T or identify alternative solutions outside this product family.

Frequently Asked Questions (FAQ)

Q: Can the A2982SLWTR-T directly replace the A2982ELW-T in existing designs?

A: Yes, the A2982SLWTR-T is a direct substitute for applications operating within the -20°C to 85°C temperature range. All electrical specifications, output configuration, current ratings, and package dimensions are identical. Verify application temperature requirements before substitution.

Q: What is the significance of the "Not For New Designs" status on the A2982SLWTR-T?

A: This designation indicates the part is available for replacement and repair of existing systems but is not recommended for new product development. For new designs, consult Allegro MicroSystems for current-generation alternatives within the A2982 family or successor product lines.

Q: Are there packaging differences between these parts?

A: Both parts use the 20-SOIC package with identical dimensions (0.295", 7.50mm width). The A2982SLWTR-T is supplied in Cut Tape (CT) and Digi-Reel® packaging, while the A2982ELW-T packaging specification is not detailed. Verify packaging requirements for your procurement and assembly processes.

Q: What compliance certifications apply to both parts?

A: Both the A2982ELW-T and A2982SLWTR-T are ROHS3 compliant, REACH unaffected, and carry MSL 3 (168 Hours) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: How do the operating temperature ranges affect substitution decisions?

A: The A2982ELW-T operates from -40°C to 85°C, while the A2982SLWTR-T operates from -20°C to 85°C. Applications requiring operation below -20°C must use the A2982ELW-T. For applications within -20°C to 85°C, both parts are functionally equivalent.
