Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX4473ESA-T is based on the following critical parameters:

• Package Compatibility: All substitute parts must use 8-SOIC (0.154", 3.90mm Width) surface mount packaging to ensure direct PCB footprint compatibility
• Regulatory Compliance: All substitutes maintain ROHS3 compliance and EAR99 export classification
• Functional Category: Substitute parts are general-purpose amplifiers with rail-to-rail output capability, representing the closest functional equivalents available in active production status
• Moisture Sensitivity: Substitutes range from MSL 1 (unlimited) to MSL 2 (1 year), both acceptable for standard handling and storage

The substitute parts listed represent active or last-time-buy status components, providing design continuity for applications previously using the obsolete MAX4473ESA-T.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status)

TLV2460ID, TLV2461CD, TLV2470ID, TLV2470IDR, and TLV2471AQDRG4Q1 are recommended as primary substitutes. All maintain active production status, ROHS3 compliance, and 8-SOIC packaging. TLV2470ID and TLV2470IDR offer extended operating temperature range (-40°C ~ 125°C) matching industrial specifications. TLV2471AQDRG4Q1 includes automotive-grade qualification (AEC-Q100) for applications requiring automotive reliability standards.

Secondary Substitutes (Last Time Buy / Obsolete Status)

TLV2460CD and TLV2461AID are available but carry last-time-buy or obsolete designations. These remain viable for near-term production but should not be selected for new long-term designs. TLV2460CD operates within 0°C ~ 70°C temperature range, suitable for commercial applications only.

Extended Supply Range

OPA379AIDR and TLV379IDR provide low-voltage operation (1.8V minimum supply) for battery-powered or low-power applications. Both maintain active status and extended temperature range (-40°C ~ 125°C).

All substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original MAX4473ESA-T specification.

Frequently Asked Questions (FAQ)

Q: Why is the MAX4473ESA-T obsolete, and what are my options?

A: The MAX4473ESA-T is classified as obsolete by the manufacturer. The substitute parts listed provide functional equivalents in active production. For immediate requirements, select from active-status parts such as TLV2460ID, TLV2470ID, or TLV2470IDR. For long-term design continuity, avoid last-time-buy and obsolete alternatives.

Q: Are all substitute parts pin-compatible with the MAX4473ESA-T?

A: All substitute parts use the same 8-SOIC (0.154", 3.90mm Width) package, ensuring PCB footprint compatibility. Pin-level functional compatibility depends on circuit application requirements and must be verified against specific application schematics.

Q: What is the difference between TLV2460ID and TLV2460CD?

A: Both use identical electrical specifications but differ in operating temperature range and product status. TLV2460ID operates -40°C ~ 125°C (active, last-time-buy status), while TLV2460CD operates 0°C ~ 70°C (active status). TLV2460ID is preferred for industrial and extended-temperature applications.

Q: Does MSL rating affect substitution decisions?

A: MSL 1 (unlimited) parts such as TLV2460ID, TLV2461CD, TLV2470ID, and TLV2470IDR require no moisture-sensitive device handling precautions. MSL 2 parts (OPA379AIDR, TLV379IDR) require 1-year shelf-life management. Both are acceptable; MSL 1 parts simplify logistics.

Q: Is TLV2471AQDRG4Q1 suitable for automotive applications?

A: Yes. TLV2471AQDRG4Q1 carries AEC-Q100 automotive qualification and is designated for automotive-grade applications. Standard commercial-grade substitutes (TLV2460ID, TLV2470ID) are not qualified for automotive use.

Q: What packaging options are available for substitute parts?

A: All substitute parts are available in 8-SOIC surface mount package. Packaging formats include tube (TLV2460CD, TLV2461CD, TLV2470ID) and tape & reel (OPA379AIDR, TLV2470IDR, TLV2471AQDRG4Q1, TLV379IDR). Tape & reel format is standard for high-volume production.
