Substitute Part Grouping Explanation

Substitution eligibility for the MAX6125ESA is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part MAX6125ESA+ qualifies as a direct equivalent based on the following criteria:

• Fixed output voltage of 2.5V
• Output current capacity of 1 mA
• Voltage tolerance of ±1%
• Temperature coefficient of 50 ppm/°C
• Input voltage range of 2.7V ~ 12.6V
• Supply current of 130 µA
• Operating temperature range of -40°C ~ 85°C
• Identical 8-SOIC package configuration
• Surface mount mounting type
• Matching noise specifications (15 µVp-p at 0.1Hz to 10Hz; 500 µVp-p at 10Hz to 10kHz)

All parameters are identical between the main part and substitute, confirming full electrical and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The MAX6125ESA+ is the direct equivalent substitute for the MAX6125ESA. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and provide identical electrical performance and mechanical compatibility. The primary distinction between these parts is product lifecycle status and regulatory compliance.

The MAX6125ESA is classified as obsolete, whereas the MAX6125ESA+ maintains active product status. For new designs or systems requiring long-term component availability, the MAX6125ESA+ is the appropriate selection. Additionally, the MAX6125ESA+ achieves ROHS3 compliance, whereas the original MAX6125ESA is RoHS non-compliant. This compliance difference may be relevant for applications subject to environmental or regulatory requirements.

Both parts are supplied in 8-SOIC surface mount packages with identical pinout and electrical characteristics, ensuring direct substitution without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can MAX6125ESA+ be used as a direct replacement for MAX6125ESA?

A: Yes. The MAX6125ESA+ is a direct equivalent substitute. All electrical parameters, output voltage, current ratings, tolerance, temperature coefficient, input voltage range, supply current, operating temperature range, and noise specifications are identical. The 8-SOIC package configuration and pinout are unchanged, enabling direct substitution without circuit redesign.

Q: What is the primary difference between MAX6125ESA and MAX6125ESA+?

A: The MAX6125ESA+ is the active production variant with ROHS3 compliance, while the MAX6125ESA is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package with identical pinout and mechanical dimensions. PCB layout and footprint remain unchanged.

Q: What is the output voltage tolerance for this reference IC?

A: The tolerance is ±1% for both the MAX6125ESA and MAX6125ESA+, ensuring the 2.5V output remains within the specified range across operating conditions.

Q: What is the operating temperature range?

A: Both parts operate across -40°C to 85°C (TA), suitable for industrial and commercial temperature environments.

Q: Is the MAX6125ESA+ suitable for applications requiring RoHS compliance?

A: Yes. The MAX6125ESA+ is ROHS3 compliant, making it appropriate for applications subject to RoHS regulations. The original MAX6125ESA is not RoHS compliant.
