Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LMH0002SQ is determined by the following critical parameters:

• Manufacturer and Base Product Number: Both the main part and substitute must originate from Texas Instruments with the same base product number (LMH0002) to ensure functional equivalence.
• Package and Pinout: The 16-WQFN (4x4) exposed pad package must be identical to guarantee mechanical and electrical compatibility on the PCB.
• Electrical Specifications: Supply voltage range (3.135V ~ 3.465V), control interface (Serial), and functional classification (Driver) must match exactly.
• Standards Compliance: DVB-ASI and SMPTE standard support must be maintained.
• Environmental and Regulatory Compliance: RoHS3 compliance, MSL rating, and REACH status must be equivalent or superior.

The substitute part LMH0002SQ/NOPB meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The LMH0002SQ/NOPB is the direct substitute for the LMH0002SQ. Both parts are manufactured by Texas Instruments and share identical electrical, mechanical, and functional specifications. The primary distinction is product status: the original LMH0002SQ is obsolete, while LMH0002SQ/NOPB maintains active product status with current manufacturing support.

The LMH0002SQ/NOPB is supplied in Tape & Reel (TR) packaging, which is the standard format for production environments. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical MSL ratings, ensuring regulatory and environmental compatibility.

For new designs or production continuity, the LMH0002SQ/NOPB is the appropriate selection due to its active product status and assured supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can LMH0002SQ/NOPB be used as a direct replacement for LMH0002SQ?

A: Yes. Both parts are functionally identical with matching electrical specifications, package configuration, and standards compliance. The primary difference is product status and packaging format.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" suffix designates the part as supplied in Tape & Reel (TR) packaging without plating on the leads, which is the standard production format for surface mount components.

Q: Are there any pinout differences between these parts?

A: No. Both parts use the identical 16-WQFN (4x4) package with exposed pad. Pinout and pad layout are identical.

Q: Why is the original LMH0002SQ listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. The LMH0002SQ/NOPB remains in active production and is the recommended part for current applications.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL ratings.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging is typically used for small quantities or legacy inventory. Tape & Reel (TR) packaging is the standard format for automated assembly and production environments, offering better handling and traceability.
