MAX1719EUT+ Equivalent & Substitute Parts
Part Overview
The MAX1719EUT+ is a charge pump switching regulator IC from Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) component. This device functions as a ratiometric charge pump regulator capable of generating positive or negative fixed output voltages (-Vin or 2Vin) with a maximum output current of 25mA. The part operates across an input voltage range of 1.5V to 5.5V and maintains a switching frequency between 60kHz and 200kHz. With an active product status and full RoHS3 compliance, the MAX1719EUT+ serves applications requiring compact voltage inversion or doubling in space-constrained surface mount designs. Substitute parts are identified based on matching electrical specifications, package configuration, and compliance certifications.

Substitute Part Grouping Explanation
Substitute parts for the MAX1719EUT+ are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:
- Identical ratiometric charge pump topology with positive or negative output configuration
- Fixed output voltage capability (-Vin or 2Vin)
- Single output configuration
- Input voltage range: 1.5V to 5.5V
- Output current: 25mA
- Switching frequency: 60kHz to 200kHz
- SOT-23-6 package configuration for surface mount applications
- Operating temperature range: -40°C to 85°C
- Active product status with RoHS3 compliance
The MAX1719EUT+T is classified as a direct substitute, differing only in packaging format (Cut Tape and Digi-Reel) while maintaining identical electrical specifications and compliance certifications.

Engineering Selection Recommendations
Both the MAX1719EUT+ and MAX1719EUT+T are active products with identical electrical specifications and full RoHS3 compliance. Selection between these parts should be based on procurement and supply chain requirements. The MAX1719EUT+ is available in standard packaging, while the MAX1719EUT+T is supplied in Cut Tape and Digi-Reel format, which may be preferred for automated assembly processes or high-volume production environments. Both parts carry MSL Level 1 (Unlimited) moisture sensitivity rating and maintain REACH unaffected status. The choice between these substitutes does not impact circuit performance or thermal characteristics, as all electrical and mechanical parameters remain identical.
Frequently Asked Questions (FAQ)
Q: Can MAX1719EUT+T be used as a direct replacement for MAX1719EUT+?
A: Yes. Both parts are electrically identical with matching input voltage range (1.5V to 5.5V), output current (25mA), switching frequency (60kHz to 200kHz), and SOT-23-6 package configuration. The only difference is packaging format.
Q: What does the packaging designation "Cut Tape (CT) & Digi-Reel®" mean for MAX1719EUT+T?
A: This indicates the part is supplied on continuous tape in cut lengths and on Digi-Reel spools, formats commonly used for automated pick-and-place assembly. Standard packaging typically refers to conventional tape and reel or tube formats.
Q: Are there any compliance differences between MAX1719EUT+ and MAX1719EUT+T?
A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity rating.
Q: What determines substitutability for the MAX1719EUT+ charge pump regulator?
A: Substitutes must match the ratiometric charge pump topology, fixed output voltage configuration (-Vin or 2Vin), 25mA output current, 1.5V to 5.5V input range, SOT-23-6 package, and -40°C to 85°C operating temperature. Active product status and RoHS3 compliance are required.
Q: Can the MAX1719EUT+ be substituted with a different topology charge pump regulator?
A: No. Substitutes must maintain the identical ratiometric charge pump topology and fixed output voltage capability. Different topologies or adjustable output configurations are not interchangeable.
