Substitute Part Grouping Explanation

Substitute parts for the LMH2191TME/NOPB are identified based on strict equivalence across the following critical parameters:

• Functional Type: Fanout Buffer (Distribution) with 1:2 input-to-output ratio
• Maximum Frequency: 52 MHz operation capability
• Supply Voltage Range: 2.5V to 5.5V compatibility
• Operating Temperature Range: -40°C to 85°C
• Package Configuration: 8-WFBGA, DSBGA (8-DSBGA supplier package)
• Mounting Technology: Surface Mount
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The LMH2191TMX/NOPB meets all these parameters and qualifies as a parametric equivalent substitute. Both parts share the same base product number (LMH2191), manufacturer (Texas Instruments), and electrical/mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the LMH2191TME/NOPB and LMH2191TMX/NOPB are active products from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts may be based on availability and supply chain considerations. The LMH2191TMX/NOPB currently maintains higher inventory levels (17,832 pcs) compared to the LMH2191TME/NOPB (1,410 pcs), which may influence procurement decisions for high-volume applications. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can the LMH2191TMX/NOPB directly replace the LMH2191TME/NOPB in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, frequency ratings, supply voltage ranges, operating temperature ranges, and package configurations. No circuit modifications are required for substitution.

Q: Are there any differences in the 8-DSBGA package between these two parts?

A: No. Both parts use the identical 8-DSBGA supplier device package with 8-WFBGA, DSBGA case designation. PCB layout and footprint compatibility are maintained.

Q: What is the significance of the different part number suffixes (TME vs. TMX)?

A: The suffix designates the specific manufacturing process or tape-and-reel configuration used by Texas Instruments. The electrical and mechanical performance remains identical across both variants.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both the LMH2191TME/NOPB and LMH2191TMX/NOPB operate across the -40°C to 85°C temperature range, meeting industrial application requirements.

Q: Do these parts require special handling during assembly?

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control measures. Standard surface mount assembly processes apply.
