Substitute Part Grouping Explanation

Substitution of the MAX975EUA is determined by strict equivalence across the following electrical and mechanical parameters:

• Output Type: CMOS, Rail-to-Rail, TTL configuration
• Supply Voltage Range: 2.7V ~ 5.25V
• Input Offset Voltage: 2mV @ 5V
• Input Bias Current: 0.1µA @ 5.25V
• Quiescent Current: 500µA maximum
• CMRR / PSRR: 82dB CMRR, 90dB PSRR
• Propagation Delay: 820ns maximum
• Hysteresis: 4mV
• Operating Temperature: -40°C ~ 85°C
• Package: 8-TSSOP/8-MSOP surface mount
• Pinout: Identical 8-pin configuration

The MAX975EUA+ meets all electrical and mechanical specifications of the original part while offering improved product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX975EUA+ is the direct functional equivalent of the MAX975EUA. Both parts share identical electrical specifications and package configurations, ensuring pin-for-pin compatibility and equivalent circuit performance.

The primary distinction between these parts is product status and regulatory compliance. The MAX975EUA is obsolete, while the MAX975EUA+ maintains active production status. Additionally, the MAX975EUA+ carries ROHS3 compliance certification, whereas the original MAX975EUA is RoHS non-compliant. Both parts maintain identical moisture sensitivity levels and REACH status.

For new designs or production continuity where the MAX975EUA is no longer available, the MAX975EUA+ provides full electrical and mechanical substitution with the added benefit of current manufacturing support and enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are the MAX975EUA and MAX975EUA+ pin-compatible?

A: Yes. Both parts use the 8-TSSOP/8-MSOP package with identical pinout and electrical characteristics. Direct board-level substitution is supported without circuit modification.

Q: What is the difference between MAX975EUA and MAX975EUA+?

A: The parts are electrically identical across all specified parameters. The primary differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. ROHS3 compliant). The MAX975EUA+ is the current production equivalent.

Q: Can I use MAX975EUA+ in applications originally designed for MAX975EUA?

A: Yes. The MAX975EUA+ meets all electrical and mechanical specifications of the MAX975EUA, including supply voltage range, input offset voltage, propagation delay, hysteresis, and operating temperature range. No circuit redesign is required.

Q: What packaging options are available for these parts?

A: Both the MAX975EUA and MAX975EUA+ are supplied in 8-TSSOP/8-MSOP surface-mount packages. The MAX975EUA is available in standard packaging, while the MAX975EUA+ is supplied in tube packaging.

Q: Are there any compliance or certification differences?

A: The MAX975EUA+ carries ROHS3 compliance certification, making it suitable for applications with RoHS regulatory requirements. The original MAX975EUA is RoHS non-compliant. Both parts maintain identical REACH and ECCN classifications.

Q: What is the moisture sensitivity level for these comparators?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
