Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMH6715MAX is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Dual-channel configuration (2 circuits minimum)
• Current feedback amplifier topology
• 8-SOIC surface mount package with 0.154" (3.90mm) width
• Supply voltage compatibility: 10V ~ 12V single supply or ±5V ~ 6V dual supply
• Output current capability: minimum 70 mA per channel
• Supply current: 5.8 mA nominal

Acceptable Parameter Variations:

• Bandwidth equal to or greater than 400 MHz
• Slew rate equal to or greater than 1300 V/µs
• Product status (active or obsolete) does not disqualify a substitute

The LMH6715MAX/NOPB and EL5263ISZ-T7 meet these criteria and are classified as direct substitutes.

Engineering Selection Recommendations

LMH6715MAX/NOPB (National Semiconductor)

This part is the direct equivalent to the LMH6715MAX with identical electrical specifications and packaging. The primary advantage is active product status, ensuring continued availability and manufacturing support. The /NOPB designation indicates lead-free, RoHS-compliant processing. Selection of LMH6715MAX/NOPB is appropriate for new designs and production continuity where the original LMH6715MAX is no longer available.

EL5263ISZ-T7 (Renesas Electronics Corporation)

This part meets all primary substitution criteria with enhanced performance characteristics: 500 MHz bandwidth (25% improvement over 400 MHz specification) and 4000 V/µs slew rate (3.08× improvement over 1300 V/µs specification). Output current per channel is 100 mA, exceeding the 70 mA requirement. Supply current is reduced to 1.5 mA per channel. The EL5263ISZ-T7 is ROHS3 compliant, addressing environmental and regulatory requirements. Despite obsolete status, this part remains suitable for applications where enhanced bandwidth and slew rate provide design margin or performance improvement.

Compliance Considerations

The LMH6715MAX is RoHS non-compliant. The LMH6715MAX/NOPB provides equivalent functionality with lead-free processing. The EL5263ISZ-T7 offers ROHS3 compliance for applications with strict environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can LMH6715MAX/NOPB be used as a direct replacement for LMH6715MAX?

A: Yes. The LMH6715MAX/NOPB is electrically and mechanically identical to the LMH6715MAX. Both devices share the same 8-SOIC package, supply voltage range (10V ~ 12V single or ±5V ~ 6V dual), bandwidth (400 MHz), slew rate (1300 V/µs), and output current (70 mA per channel). The /NOPB designation indicates lead-free processing and RoHS compliance. No circuit modifications are required.

Q: Is the EL5263ISZ-T7 a pin-compatible substitute?

A: Yes. The EL5263ISZ-T7 is housed in the same 8-SOIC (0.154", 3.90mm Width) package as the LMH6715MAX. Pin compatibility is confirmed. However, the EL5263ISZ-T7 exhibits superior performance: 500 MHz bandwidth versus 400 MHz, 4000 V/µs slew rate versus 1300 V/µs, and 100 mA output current per channel versus 70 mA. These enhancements may require circuit validation to ensure stability and prevent unintended performance changes.

Q: What are the key differences between LMH6715MAX/NOPB and EL5263ISZ-T7?

A: LMH6715MAX/NOPB maintains identical specifications to the original LMH6715MAX, providing a direct replacement. EL5263ISZ-T7 offers enhanced performance: 25% higher bandwidth, 3.08× higher slew rate, and 43% higher output current per channel. Supply current is lower in the EL5263ISZ-T7 (1.5 mA per channel versus 5.8 mA total). The EL5263ISZ-T7 is ROHS3 compliant, while LMH6715MAX/NOPB compliance status is not specified in available data.

Q: Can both substitute parts operate with ±5V dual supply?

A: Yes. Both LMH6715MAX/NOPB and EL5263ISZ-T7 support ±5V ~ ±6V dual supply operation. The EL5263ISZ-T7 specifies a minimum supply span of 5V and maximum of 12V, confirming compatibility with ±5V dual supply configurations.

Q: What is the operating temperature range for these substitutes?

A: The LMH6715MAX/NOPB operating temperature range is not specified in the provided data. The EL5263ISZ-T7 operates across -40°C to 85°C (TA). For applications requiring extended temperature performance, the EL5263ISZ-T7 provides documented specifications.

Q: Are there any RoHS or environmental compliance differences?

A: The LMH6715MAX is RoHS non-compliant. The LMH6715MAX/NOPB provides lead-free processing (indicated by /NOPB designation), though full RoHS compliance status is not specified. The EL5263ISZ-T7 is ROHS3 compliant. For applications with strict environmental or regulatory requirements, the EL5263ISZ-T7 is the appropriate selection.
