INA101KUE4 Equivalent & Substitute Parts

Part Overview

The INA101KUE4 is an instrumentation amplifier manufactured by Texas Instruments, featuring a single circuit in a 16-SOIC surface mount package. This device is designed for precision signal conditioning applications requiring low input offset voltage and low input bias current. The INA101KUE4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the INA101KUE4 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Amplifier type (instrumentation), number of circuits (1), slew rate (0.4 V/µs), -3dB bandwidth (300 kHz), input bias current (15 nA), input offset voltage (125 µV), supply current (6.7 mA), output current per channel (10 mA), and supply voltage range (10 V to 40 V).

Mechanical & Environmental: Package type (16-SOIC), mounting method (surface mount), operating temperature range (0°C to 70°C), moisture sensitivity level (MSL 3), and physical dimensions (0.295" × 7.50mm width).

Compliance & Status: RoHS3 compliance and REACH unaffected status are required for regulatory equivalence.

The INA101KU meets all these criteria and is designated as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The INA101KU is the direct equivalent substitute for the discontinued INA101KUE4. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The primary distinction is product status: the INA101KUE4 is discontinued, while the INA101KU maintains active status with current inventory availability.

For applications currently using the INA101KUE4, the INA101KU provides full functional compatibility without design modification. Both parts comply with ROHS3 regulations and maintain REACH unaffected status, ensuring regulatory continuity. The identical package, pinout, and electrical performance enable direct substitution in existing PCB layouts and circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the INA101KU be used as a direct replacement for the INA101KUE4?

A: Yes. The INA101KU is electrically and mechanically identical to the INA101KUE4 across all specified parameters. Both devices feature the same 16-SOIC package, identical electrical performance, and equivalent compliance certifications. Direct substitution is supported without circuit modification.

Q: What is the difference between the INA101KUE4 and INA101KU?

A: The primary difference is product status. The INA101KUE4 is discontinued at DiGi Electronics, while the INA101KU remains in active production. All electrical specifications, package dimensions, and performance characteristics are identical.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in 16-SOIC surface mount packages with identical physical dimensions (0.295" × 7.50mm width). The packaging format is tube for both variants.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the INA101KUE4 and INA101KU are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is MSL 3 (168 hours) for both parts.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution is based on matching amplifier type (instrumentation), circuit count (1), slew rate (0.4 V/µs), bandwidth (300 kHz), input bias current (15 nA), input offset voltage (125 µV), supply current (6.7 mA), output current (10 mA), and supply voltage range (10 V to 40 V).
