LM613IWM Equivalent & Substitute Parts

Part Overview

The LM613IWM is a linear amplifier, comparator, and reference IC manufactured by Texas Instruments, designed for power supply monitoring applications. This device is packaged in a 16-SOIC surface mount configuration with a width of 7.50mm. The LM613IWM is classified as an obsolete product, which necessitates identification of functionally equivalent substitute components for ongoing design support and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM613IWM is determined by the following critical parameters:

Functional Equivalence: Both the main part and substitute must operate as amplifier, comparator, and reference ICs within the linear amplifier category.

Package Compatibility: The substitute must be a surface mount device. While the LM613IWM uses 16-SOIC packaging, the substitute TSM102AIPW uses 16-TSSOP packaging. Both are 16-pin surface mount packages with compatible pinout configurations for this device class.

Application Alignment: The substitute must support power management or power supply monitoring functions.

Regulatory Compliance: The substitute TSM102AIPW is ROHS3 compliant and carries improved moisture sensitivity characteristics (MSL 1, Unlimited), addressing modern environmental and reliability standards.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Product Replacement: The LM613IWM is classified as obsolete. The TSM102AIPW is designated as Last Time Buy, providing a defined procurement window for transition planning.

For Regulatory Compliance: If RoHS3 compliance is required for new designs or procurement cycles, the TSM102AIPW is the appropriate selection, as it meets ROHS3 standards while the LM613IWM does not.

For Moisture Sensitivity Requirements: The TSM102AIPW offers superior moisture handling characteristics (MSL 1, Unlimited) compared to the LM613IWM (MSL 2A, 4 Weeks), reducing storage and handling constraints in manufacturing environments.

For Package Footprint Considerations: The TSM102AIPW uses 16-TSSOP packaging with a narrower width (4.40mm) compared to the 16-SOIC package of the LM613IWM (7.50mm). PCB layout modifications are required for this substitution.

Frequently Asked Questions (FAQ)

Q: Can the TSM102AIPW directly replace the LM613IWM without PCB modifications?

A: Both devices are 16-pin surface mount amplifier, comparator, and reference ICs from Texas Instruments. However, the package types differ: LM613IWM uses 16-SOIC while TSM102AIPW uses 16-TSSOP. PCB footprint redesign is necessary for physical compatibility.

Q: What is the significance of the product status difference between these parts?

A: The LM613IWM is obsolete, meaning it is no longer manufactured and existing inventory is limited. The TSM102AIPW is Last Time Buy, indicating a defined final procurement period before discontinuation. This status difference underscores the importance of transitioning to the substitute part.

Q: Are there electrical parameter differences between these devices?

A: The provided specifications confirm both devices function as amplifier, comparator, and reference ICs within the linear amplifier category. Detailed electrical characteristics (gain, bandwidth, offset voltage, etc.) are not included in the provided parameters and must be verified through device datasheets for specific application requirements.

Q: Does the TSM102AIPW meet modern environmental standards?

A: Yes. The TSM102AIPW is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards. The LM613IWM is RoHS non-compliant with MSL 2A (4 Weeks) rating.

Q: What is the packaging difference and why does it matter?

A: The LM613IWM uses 16-SOIC (0.295" width, 7.50mm), while the TSM102AIPW uses 16-TSSOP (0.173" width, 4.40mm). The TSSOP package is narrower and requires different PCB land patterns. This affects board layout, assembly tooling, and component placement density.

Q: Are both parts subject to the same export regulations?

A: Yes. Both the LM613IWM and TSM102AIPW carry ECCN classification EAR99 and HTSUS code 8542.33.0001, indicating identical export control and tariff classification.
