Substitute parts must match all parameters listed above. Parts that differ in any of these specifications are not considered direct equivalents and require full circuit re-evaluation.

Parameter Comparison

Engineering Selection Recommendations

LMH6502MA/NOPB is the direct functional equivalent to the LMH6502MA. All electrical, thermal, and mechanical parameters are identical. The primary differences are:

Product Status: The LMH6502MA/NOPB carries Active product status, whereas the LMH6502MA is Obsolete. For new designs and ongoing production, the LMH6502MA/NOPB is the recommended selection to ensure long-term component availability and manufacturer support.

Compliance: The LMH6502MA/NOPB is ROHS3 Compliant, compared to the RoHS non-compliant status of the LMH6502MA. This distinction is significant for applications subject to RoHS regulations and environmental compliance requirements.

Packaging: The LMH6502MA/NOPB is supplied in Tube packaging, whereas the original part packaging is not specified. Verify packaging requirements for your assembly process.

Moisture Sensitivity: Both parts share MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.

REACH and ECCN: Both parts maintain identical REACH Unaffected status and EAR99 ECCN classification.

For direct pin-for-pin replacement in existing designs, the LMH6502MA/NOPB provides full electrical and mechanical compatibility with identical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can LMH6502MA/NOPB be used as a direct replacement for LMH6502MA in existing designs?

A: Yes. The LMH6502MA/NOPB is electrically and mechanically identical to the LMH6502MA. All functional parameters, including slew rate, bandwidth, supply voltage range, current specifications, and operating temperature range are identical. Pin configuration and package dimensions (14-SOIC, 0.154" width) are the same. No circuit modifications are required.

Q: What is the significance of the Obsolete status for LMH6502MA?

A: Obsolete status indicates that Texas Instruments has discontinued active production and support for the LMH6502MA. The LMH6502MA/NOPB, with Active status, is the current production equivalent. For new designs and long-term supply assurance, the LMH6502MA/NOPB is the appropriate selection.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The LMH6502MA is RoHS non-compliant, while the LMH6502MA/NOPB is ROHS3 Compliant. If your application or market requires RoHS compliance, the LMH6502MA/NOPB must be selected.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the LMH6502MA and LMH6502MA/NOPB are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints. Standard handling and storage practices apply.

Q: What is the difference between the packaging specifications?

A: The LMH6502MA/NOPB is supplied in Tube packaging. The original LMH6502MA packaging type is not specified in the available data. Confirm your assembly process requirements for tape-and-reel or tube packaging compatibility.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts share identical specifications: 1800 V/µs slew rate, 130 MHz -3dB bandwidth, 9 µA input bias current, 27 mA supply current, 90 mA output current per channel, 5V to 12V supply range, and -40°C to 85°C operating temperature range.

Q: Can I use LMH6502MA/NOPB in legacy systems designed for LMH6502MA?

A: Yes. The LMH6502MA/NOPB provides full backward compatibility. Identical pin configuration, package dimensions, and electrical performance ensure direct substitution without design changes.
