INA2134UA/2K5E4 Equivalent & Substitute Parts

Part Overview

The INA2134UA/2K5E4 is a differential receiver integrated circuit designed for audio line reception applications. This component is a 14-SOIC surface mount device manufactured by Texas Instruments and classified as a linear amplifier. The part is currently discontinued at DiGi Electronics, making identification of active equivalent components essential for ongoing design support and procurement.

The INA2134UA/2K5E4 serves as an audio differential line receiver in applications requiring precision signal conditioning. Due to its discontinued status, sourcing active alternatives with identical electrical and mechanical specifications is necessary for production continuity and new design implementations.

Substitute Part Grouping Explanation

Substitution of the INA2134UA/2K5E4 is determined by strict alignment of the following parameters:

Critical Substitution Parameters:

• Base product number: INA2134
• Package type: 14-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Application category: Audio differential reception
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 3 (168 Hours)
• REACH status: REACH Unaffected

The INA2134UA/2K5E4 is part of the INA2134 product family. Equivalent parts within this family maintain identical electrical performance characteristics, pinout configuration, and mechanical dimensions. Substitutes must be active products with confirmed availability to ensure procurement viability.

Parameter Comparison

Engineering Selection Recommendations

The INA2134UA/2K5 is the active equivalent substitute for the discontinued INA2134UA/2K5E4. Both components share identical electrical specifications, pinout configuration, and mechanical packaging. The substitute part maintains full compliance with ROHS3 and REACH requirements, ensuring regulatory alignment with the original component.

The primary distinction between the main part and substitute is product status: the INA2134UA/2K5E4 is discontinued, while the INA2134UA/2K5 is an active product with significantly higher inventory availability (10140 units versus 1166 units). The substitute is available in Cut Tape (CT) and Digi-Reel packaging formats, supporting both prototype and production-volume procurement requirements.

For new designs and production continuity, the INA2134UA/2K5 is the recommended active component selection. Existing designs utilizing the INA2134UA/2K5E4 can transition to the INA2134UA/2K5 without circuit modification or re-qualification, as both components are functionally and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Can the INA2134UA/2K5 directly replace the INA2134UA/2K5E4 in existing designs?

A: Yes. Both components are identical differential receiver ICs with the same base product number (INA2134), package type (14-SOIC), pinout configuration, and electrical specifications. No circuit modifications are required for substitution.

Q: What is the difference between INA2134UA/2K5E4 and INA2134UA/2K5?

A: The primary difference is product status. The INA2134UA/2K5E4 is discontinued at DiGi Electronics, while the INA2134UA/2K5 is an active product. Both components are electrically and mechanically identical. The suffix variation reflects different manufacturing or distribution batches, not functional differences.

Q: Are there packaging differences between the substitute and main part?

A: Both components use the 14-SOIC (0.154", 3.90mm Width) surface mount package. The substitute is available in Cut Tape (CT) and Digi-Reel packaging options, providing flexibility for different procurement volumes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the INA2134UA/2K5E4 and INA2134UA/2K5 are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 3, 168 Hours). Regulatory and environmental compliance is equivalent.

Q: What is the inventory status for the substitute part?

A: The INA2134UA/2K5 has 10140 units in stock as new original inventory, compared to 1166 units for the discontinued INA2134UA/2K5E4. The substitute offers significantly higher availability for production requirements.

Q: Can I use the INA2134UA/2K5 in audio differential line receiver applications?

A: Yes. The INA2134UA/2K5 is specified for audio applications as a differential receiver IC. It is functionally identical to the main part and suitable for all audio line reception circuit implementations.
