INA207AIDR Equivalent & Substitute Parts

Part Overview

The INA207AIDR is a high-side current monitor IC manufactured by Texas Instruments, designed for power management applications. This device features ±4.6% accuracy and operates across an input voltage range of -16V to 80V with a 1mA output current. The INA207AIDR is packaged in a 14-SOIC surface mount configuration and is currently classified as obsolete. Due to its obsolete status, identifying active equivalent and substitute parts is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the INA207AIDR is determined by the following critical parameters:

Package Compatibility: The 14-SOIC package is the primary mechanical constraint. Substitute parts must maintain identical package dimensions (0.154", 3.90mm Width) to ensure PCB layout compatibility without redesign.

Electrical Performance: High-side sensing method, input voltage range (-16V ~ 80V), and 1mA output current define the functional requirements. All substitute parts maintain these specifications.

Accuracy Specification: The ±4.6% accuracy tolerance is a key performance criterion. Substitute parts either match this specification or provide equal or better accuracy.

Compliance & Regulatory: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical MSL ratings (2, 1 Year), ensuring regulatory and environmental compatibility.

Product Status: Active substitute parts are preferred over the obsolete INA207AIDR to ensure long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (14-SOIC Package): The INA203AIDR, INA204AIDR, INA205AIDR, INA206AIDR, and INA208AIDR are parametric equivalents to the INA207AIDR. All maintain identical electrical specifications (±4.6% accuracy, -16V ~ 80V input, 1mA output, -40°C ~ 125°C operating range) and package configuration (14-SOIC). These parts are all active products, ensuring supply chain continuity. Selection among these equivalents may be based on inventory availability and procurement lead times.

Alternative Package Option (SOT-23-5): The INA197AIDBVR offers improved accuracy (±3%) and is actively manufactured with substantial inventory availability (26,300 pcs). However, this part uses a SOT-23-5 package, which differs mechanically from the 14-SOIC package. PCB layout redesign is required for this substitution. This option is suitable only when design flexibility permits package migration.

Compliance Assurance: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 2 (1 Year) ratings, ensuring regulatory and environmental compatibility with the original INA207AIDR.

Frequently Asked Questions (FAQ)

Q: Can I directly replace INA207AIDR with INA203AIDR, INA204AIDR, INA205AIDR, INA206AIDR, or INA208AIDR without PCB modification?

A: Yes. These parts are parametric equivalents with identical package dimensions (14-SOIC, 0.154", 3.90mm Width), electrical specifications, and pin configurations. Direct PCB substitution is possible without layout changes.

Q: What is the difference between the 14-SOIC substitute parts (INA203AIDR, INA204AIDR, INA205AIDR, INA206AIDR, INA208AIDR)?

A: All five parts share identical electrical and mechanical specifications. The differences lie in their base product numbers (INA203, INA204, INA205, INA206, INA208) and current inventory levels. Selection should be based on procurement availability and lead times.

Q: Why is INA197AIDBVR listed as a substitute if it uses a different package?

A: INA197AIDBVR is classified as a manufacturer-recommended alternative due to its superior accuracy (±3% versus ±4.6%) and high inventory availability. However, it requires PCB redesign due to its SOT-23-5 package. This option is suitable for new designs or redesign projects where package migration is feasible.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (INA203AIDR, INA204AIDR, INA205AIDR, INA206AIDR, INA208AIDR, and INA197AIDBVR) are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original INA207AIDR.

Q: What is the MSL rating for these parts, and why does it matter?

A: All parts carry MSL 2 (1 Year) rating. This indicates moisture sensitivity level and shelf life requirements. Parts must be stored in controlled humidity environments and used within one year of opening the moisture barrier bag to prevent solderability issues during assembly.

Q: Which substitute part should I choose for new designs?

A: For new designs with package flexibility, INA197AIDBVR is recommended due to its superior ±3% accuracy and active manufacturing status with high inventory. For designs requiring the 14-SOIC package, any of the five parametric equivalents (INA203AIDR through INA208AIDR) are suitable based on availability.
