Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4080SASA-T is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Amplifier type classification as current sense
• Single circuit configuration
• Bandwidth specification of 250 kHz
• Input bias current of 5 µA
• Input offset voltage of 100 µV
• Supply current of 75 µA
• Supply voltage range spanning 4.5 V minimum to 76 V maximum
• Operating temperature range of -40°C to 125°C

Mechanical & Packaging Specifications:

• 8-SOIC package with 0.154" (3.90mm) width
• Surface mount mounting type

Compliance & Regulatory:

• ROHS3 compliance
• REACH unaffected status
• MSL rating of 1 (unlimited moisture sensitivity)

Substitute parts must match all electrical, mechanical, and compliance parameters without deviation. Parts meeting these criteria are classified as direct functional equivalents suitable for component replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The MAX4080SASA+T is a direct functional equivalent to the MAX4080SASA-T. Both parts share identical electrical specifications, mechanical packaging, and regulatory compliance certifications.

Key Differentiation:

The MAX4080SASA-T is classified as obsolete, while the MAX4080SASA+T maintains active product status. This distinction is significant for supply chain planning and long-term component availability.

The MAX4080SASA+T is available in standard packaging formats (Cut Tape and Digi-Reel®), which supports both prototype and production-volume procurement workflows. The MAX4080SASA-T packaging format is not specified in available documentation.

Selection Basis:

For new designs or production transitions, the MAX4080SASA+T is the appropriate selection due to its active status and assured long-term availability. For existing designs currently using the MAX4080SASA-T, the MAX4080SASA+T provides direct substitution without circuit modification or re-qualification requirements, as all electrical and mechanical parameters are identical.

Both parts comply with ROHS3 and REACH regulatory requirements, ensuring compatibility with environmental and hazardous substance restrictions.

Frequently Asked Questions (FAQ)
