MAX629ESA-T Equivalent & Substitute Parts

Part Overview

The MAX629ESA-T is a boost, flyback, and SEPIC switching regulator IC manufactured by Analog Devices Inc./Maxim Integrated. It provides positive or negative adjustable output voltage from ±0.8V to ±28V with a maximum output current of 500mA. The device operates at a switching frequency of 300kHz and is housed in an 8-SOIC surface mount package.

The MAX629ESA-T is classified as obsolete. For new designs and ongoing production requirements, direct substitutes with active product status are available to ensure long-term supply chain reliability and continued manufacturer support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX629ESA-T is determined by electrical and mechanical parameter equivalence. The substitute part must maintain identical specifications across the following critical parameters:

• Input voltage range (2.7V to 5.5V)
• Output voltage range (±0.8V to ±28V adjustable)
• Output current capability (500mA)
• Switching frequency (300kHz)
• Operating temperature range (-40°C to 85°C)
• Package configuration (8-SOIC surface mount)
• Output configuration (positive or negative)
• Supported topologies (boost, flyback, SEPIC)
• Regulatory compliance (ROHS3, REACH Unaffected)

The MAX629ESA+T meets all electrical and mechanical requirements for direct substitution. The primary distinction is product status: the substitute part maintains active manufacturer support and current production availability.

Parameter Comparison

Engineering Selection Recommendations

The MAX629ESA+T is the direct substitute for the MAX629ESA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications. The MAX629ESA+T maintains active product status with current manufacturer support and production availability, whereas the MAX629ESA-T is classified as obsolete.

For applications currently using the MAX629ESA-T, the MAX629ESA+T provides equivalent functionality without design modification. Both parts comply with ROHS3 and REACH requirements and are suitable for the same operating conditions and topologies.
