MAX619ESA-T Equivalent & Substitute Parts

Part Overview

The MAX619ESA-T is a charge pump switching regulator IC manufactured by Analog Devices Inc./Maxim Integrated, designed for step-up voltage conversion with a fixed 5V output at 50mA. This device converts input voltages between 2V and 3.6V to a regulated 5V output using charge pump topology. The MAX619ESA-T is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Direct replacements and functionally equivalent alternatives are available from the same manufacturer family.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX619ESA-T is determined by the following critical parameters:

• Output voltage specification (5V fixed)
• Output current capability (50mA minimum)
• Input voltage range compatibility (2V to 3.6V minimum support)
• Package type (8-SOIC form factor)
• Charge pump topology
• Surface mount mounting type
• RoHS3 compliance

The substitute parts are grouped into two categories:

Direct Manufacturer Variant: MAX619ESA+T is an active product variant from the same MAX619 base product line with identical electrical specifications and packaging.

Functionally Equivalent Alternatives: LTC1516 series parts (LTC1516CS8#PBF, LTC1516CS8#TRPBF, LTC1516IS8#PBF, LTC1516IS8#TRPBF) provide equivalent charge pump regulation with the same output voltage, current rating, and package footprint. These parts accept a wider input voltage range (2V to 5V) and operate at 600kHz switching frequency.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: MAX619ESA+T is the primary substitute, offering identical electrical specifications and operating temperature range while maintaining active product status. This part is recommended when existing designs require no modification and active component availability is prioritized.

For Extended Input Voltage Range: LTC1516IS8#PBF and LTC1516IS8#TRPBF support the full -40°C to 85°C operating temperature range and accept input voltages up to 5V, providing design flexibility for applications requiring higher input voltage tolerance. The tape and reel variant (LTC1516IS8#TRPBF) is suitable for high-volume production.

For Commercial Temperature Range Applications: LTC1516CS8#PBF and LTC1516CS8#TRPBF operate within 0°C to 70°C and are appropriate for non-industrial applications where extended temperature performance is not required. These parts offer cost optimization for commercial-grade designs.

All substitute parts maintain ROHS3 compliance, identical package footprint, and equivalent charge pump topology, ensuring PCB-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can MAX619ESA+T be used as a direct drop-in replacement for MAX619ESA-T?

A: Yes. MAX619ESA+T provides identical electrical specifications, operating temperature range (-40°C to 85°C), output voltage (5V), output current (50mA), input voltage range (2V to 3.6V), and 8-SOIC package footprint. The primary difference is product status: MAX619ESA+T is active while MAX619ESA-T is obsolete.

Q: What are the key differences between MAX619 and LTC1516 series parts?

A: Both provide 5V fixed output at 50mA with 8-SOIC packaging. LTC1516 parts accept a wider input voltage range (2V to 5V versus 2V to 3.6V) and operate at 600kHz switching frequency versus 500kHz. Temperature range varies by grade: LTC1516IS8 supports -40°C to 85°C (matching MAX619), while LTC1516CS8 is limited to 0°C to 70°C.

Q: Does switching frequency difference affect circuit design?

A: The 100kHz frequency difference (500kHz versus 600kHz) does not require circuit redesign. Both frequencies are within the same operational band for charge pump regulators. Output filtering and component selection remain compatible across both frequency specifications.

Q: Are packaging format options (Tube versus Tape & Reel) electrically equivalent?

A: Yes. Tube and Tape & Reel packaging formats contain identical die and electrical specifications. The difference is mechanical packaging only, affecting handling and automated assembly processes. Selection depends on production volume and assembly equipment compatibility.

Q: Which substitute part is recommended for new designs?

A: LTC1516IS8#TRPBF or LTC1516IS8#PBF are recommended for new designs. These parts offer active product status, extended input voltage range (2V to 5V), full industrial temperature range (-40°C to 85°C), and high inventory availability. Tape & Reel format (LTC1516IS8#TRPBF) is preferred for production volumes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original MAX619ESA-T specification.
