Substitute Part Grouping Explanation

Substitution of the MAX4080TASA-T is determined by strict equivalence across all electrical and mechanical parameters. The substitute relationship is based on matching the following critical parameters:

• Amplifier Type: Current Sense
• Number of Circuits: 1
• Bandwidth: 250 kHz
• Input Bias Current: 5 µA
• Input Offset Voltage: 100 µV
• Supply Current: 75 µA
• Supply Voltage Range: 4.5 V to 76 V
• Operating Temperature: -40°C to 125°C
• Package: 8-SOIC (0.154", 3.90mm Width)
• Mounting: Surface Mount
• Compliance: ROHS3, REACH Unaffected

The substitute part identified maintains identical electrical specifications and mechanical compatibility, differing only in product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The MAX4080TASA+T serves as the direct substitute for the MAX4080TASA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: the MAX4080TASA-T is classified as Obsolete, while the MAX4080TASA+T maintains Active status. The substitute part is currently in production and maintains higher inventory availability (15,496 pieces in stock versus 744 pieces for the obsolete variant).

Both parts comply with ROHS3 requirements and carry REACH Unaffected status, ensuring regulatory compliance for new designs and ongoing production. The packaging format differs (Tube versus Cut Tape & Digi-Reel®), but this represents a logistical distinction rather than a functional or electrical difference.

For applications currently utilizing the MAX4080TASA-T, the MAX4080TASA+T provides full functional equivalence with improved supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the MAX4080TASA+T directly replace the MAX4080TASA-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The substitute part operates within the same voltage range (4.5 V to 76 V), maintains identical bandwidth (250 kHz), input bias current (5 µA), and input offset voltage (100 µV). The 8-SOIC package dimensions and surface mount configuration are identical.

Q: What is the difference between the MAX4080TASA-T and MAX4080TASA+T?

A: The parts differ in product status and packaging format. The MAX4080TASA-T is Obsolete; the MAX4080TASA+T is Active. The MAX4080TASA-T is supplied in Tube packaging, while the MAX4080TASA+T is supplied in Cut Tape (CT) and Digi-Reel® formats. All electrical and mechanical specifications are identical.

Q: Are there compliance differences between these parts?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant and REACH Unaffected status. Both are suitable for applications requiring regulatory compliance.

Q: What is the operating temperature range for both parts?

A: Both the MAX4080TASA-T and MAX4080TASA+T operate across -40°C to 125°C.

Q: Is the 8-SOIC package compatible with existing PCB layouts?

A: Yes. Both parts use the identical 8-SOIC package with 0.154" (3.90mm) width. PCB footprints, land patterns, and assembly processes remain unchanged.

Q: Why is the MAX4080TASA-T marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. The MAX4080TASA+T represents the current production equivalent and is recommended for new designs and ongoing supply requirements.
