LM613IWM/NOPB Equivalent & Substitute Parts

Part Overview

The LM613IWM/NOPB is a linear amplifier, comparator, and reference IC manufactured by Texas Instruments, designed for power supply monitoring applications. This device is classified as Obsolete, indicating it is no longer in active production. The part is housed in a 16-SOIC package with a width of 7.50mm and operates as a surface mount component.

Due to its obsolete status, sourcing new original inventory becomes increasingly difficult. Identifying qualified substitute parts ensures design continuity and maintains supply chain reliability for applications requiring amplifier, comparator, and reference functionality in power supply monitoring circuits.

Key Parameters

Substitute Part Grouping Explanation

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

Functional Compatibility:

• Device Type: Amplifier, Comparator, Reference IC
• Application Category: Power Supply Monitoring / Power Management
• Manufacturer: Texas Instruments (same manufacturer ensures design continuity)

Physical & Electrical Compatibility:

• Mounting Type: Surface Mount (required for PCB integration)
• Pin Count: 16-pin configuration
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• REACH Status: REACH Unaffected (regulatory requirement)

Package Considerations:

• Original package: 16-SOIC (0.295", 7.50mm Width)
• Substitute packages must accommodate 16-pin surface mount requirements
• Package footprint differences require PCB layout evaluation

The TSM102AIPW qualifies as a manufacturer-recommended substitute based on matching functional classification, pin count, surface mount technology, and regulatory compliance standards.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The LM613IWM/NOPB carries an Obsolete status, while the TSM102AIPW is designated Last Time Buy. This distinction indicates that the substitute part remains available through Texas Instruments but with limited future availability. Selection of the TSM102AIPW extends the viable sourcing window for this functional category.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying current environmental and regulatory requirements. Both are classified under ECCN EAR99 and HTSUS code 8542.33.0001, ensuring consistent export and tariff classification.

Moisture Sensitivity: The substitute part (TSM102AIPW) offers improved moisture handling characteristics with MSL 1 (Unlimited) compared to the original part's MSL 3 (168 Hours). This provides enhanced reliability in storage and handling scenarios.

Package Transition: The TSM102AIPW uses a 16-TSSOP package (0.173", 4.40mm Width) versus the original 16-SOIC package (0.295", 7.50mm Width). This represents a package footprint change requiring PCB layout modification. The TSSOP package is narrower, potentially enabling more compact board designs.

Frequently Asked Questions (FAQ)

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

A: No. While both devices are 16-pin surface mount amplifier, comparator, and reference ICs from Texas Instruments, they use different package types (SOIC versus TSSOP). PCB footprint redesign is required. Pin-to-pin functional compatibility must be verified against the respective datasheets.

Q: What is the significance of the "Last Time Buy" status for the TSM102AIPW?

A: Last Time Buy indicates that Texas Instruments will accept orders for a limited period before discontinuing the part. This status provides a defined window for procurement but does not guarantee indefinite availability. Long-term supply planning should account for this limitation.

Q: Are there regulatory or compliance differences between these parts?

A: No. Both parts maintain identical regulatory classifications: ROHS3 Compliant, REACH Unaffected, ECCN EAR99, and HTSUS 8542.33.0001. They satisfy the same environmental and export requirements.

Q: What does the MSL rating difference mean for handling?

A: The LM613IWM/NOPB requires moisture-controlled storage for 168 hours at MSL 3 conditions. The TSM102AIPW, rated MSL 1, has unlimited moisture sensitivity tolerance, simplifying storage and handling procedures and reducing risk of moisture-induced failures.

Q: Is the TSM102AIPW the only qualified substitute?

A: Based on the provided input parameters, the TSM102AIPW is identified as the manufacturer-recommended substitute. Additional alternatives may exist but are not included in this reference.

Q: What package considerations apply to the TSSOP format?

A: The 16-TSSOP package is narrower (4.40mm) than the 16-SOIC (7.50mm), enabling more compact layouts. However, TSSOP packages typically have finer pitch and smaller lead dimensions, which may require updated assembly and soldering specifications. Consult manufacturing guidelines for thermal and mechanical requirements.
