MAX619EPA+ Equivalent & Substitute Parts

Part Overview

The MAX619EPA+ is a charge pump switching regulator IC manufactured by Analog Devices Inc./Maxim Integrated. It functions as a step-up converter, generating a fixed positive 5V output from a 2V to 3.6V input supply with 50mA output current capability. The device operates at 500kHz switching frequency and is housed in an 8-DIP through-hole package.

This part is classified as obsolete. Identifying equivalent and substitute parts is necessary for design continuity, procurement planning, and system maintenance when original stock becomes unavailable or when redesign requirements necessitate alternative solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX619EPA+ is determined by strict equivalence across the following critical parameters:

• Output voltage specification (5V fixed)
• Output current capability (50mA minimum)
• Input voltage range compatibility (2V to 3.6V)
• Switching topology (charge pump step-up converter)
• Package form factor (8-DIP through-hole)
• Operating temperature range (-40°C to 85°C)
• Regulatory compliance (RoHS3)

Only parts meeting all these criteria simultaneously qualify as direct substitutes. The MAX619EPA+ represents the complete specification set for this application; no alternative parts with differing electrical or mechanical parameters are presented as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The MAX619EPA+ is the specified component for applications requiring a 5V output from 2V to 3.6V input sources with 50mA capacity in an 8-DIP through-hole package. Given its obsolete status, component sourcing should prioritize verified new original stock from authorized distributors.

Selection of alternative parts must maintain strict compliance with all electrical parameters: fixed 5V output, 50mA output current, 2V to 3.6V input range, and 8-DIP package form factor. RoHS3 compliance and operating temperature range specifications must be verified for any candidate part.

For applications where the through-hole 8-DIP package is not a design constraint, surface-mount alternatives with identical electrical specifications may be evaluated, provided all other parameters remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can I use a different output voltage regulator as a substitute for the MAX619EPA+?

A: No. The MAX619EPA+ is specified for fixed 5V output. Any substitute must provide identical 5V output voltage. Regulators with adjustable or different fixed output voltages are not compatible.

Q: What if I need higher output current than 50mA?

A: The MAX619EPA+ is rated for 50mA output current. If your application requires higher current, a different regulator with higher current rating must be selected. This would not be a substitute but a redesign requirement.

Q: Is the 8-DIP package mandatory for substitution?

A: The 8-DIP through-hole package is part of the specification. If your PCB design requires this specific package form factor, only parts in 8-DIP packaging qualify as substitutes. Surface-mount alternatives would require PCB redesign.

Q: Can I substitute the MAX619EPA+ with a different manufacturer's part?

A: Yes, provided the alternative part meets all electrical and mechanical specifications: 5V fixed output, 50mA current, 2V to 3.6V input range, 500kHz switching frequency, 8-DIP package, -40°C to 85°C operating range, and RoHS3 compliance.

Q: What does the obsolete status mean for my design?

A: Obsolete status indicates the part is no longer in active production. Existing stock from authorized distributors may be available, but long-term availability is not guaranteed. Designs should consider migration to current production alternatives or secure adequate inventory for product lifecycle requirements.

Q: Are there any compliance concerns with using the MAX619EPA+?

A: The MAX619EPA+ is RoHS3 compliant and REACH unaffected. It meets current regulatory requirements for electronic component use in most applications. Verify compliance requirements for your specific end-use application and geographic market.
