MAX1763EEE-T Equivalent & Substitute Parts

Part Overview

The MAX1763EEE-T is a boost switching regulator IC from Analog Devices Inc./Maxim Integrated, designed for positive adjustable/fixed output voltage regulation. This device functions as a step-up converter with a single output capable of delivering 2A switch current, operating across an input voltage range of 0.7V to 5.5V with selectable output configurations of 2.5V or 3.3V up to 5.5V maximum. The part is currently listed as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX1763EEE-T is determined by strict equivalence across the following critical parameters:

• Topology & Function: Boost switching regulator with step-up conversion capability
• Output Configuration: Single positive output, adjustable/fixed voltage selection
• Electrical Performance: Input voltage range 0.7V–5.5V; output voltage 2.5V/3.3V fixed or up to 5.5V adjustable; 2A switch current capability
• Switching Frequency: 750kHz–1.25MHz operating range
• Synchronous Rectification: Integrated synchronous rectifier required
• Package Compatibility: 16-SSOP (0.154", 3.90mm Width) surface mount package
• Temperature Range: -40°C to 85°C operating specification

The MAX1763EEE+T qualifies as a direct substitute based on identical electrical specifications, package geometry, and pinout compatibility. The primary distinction is packaging format (tape & reel vs. tube) and product status (active vs. obsolete).

Parameter Comparison

Engineering Selection Recommendations

The MAX1763EEE+T is the direct functional equivalent of the MAX1763EEE-T. Selection between these parts is determined by application requirements and regulatory compliance:

MAX1763EEE+T is the preferred choice for new designs and production applications. This part is currently in active production status, ensuring long-term availability and supply chain continuity. The MAX1763EEE+T carries ROHS3 compliance certification, meeting current environmental and material restriction standards. Tape & reel packaging is standard for automated assembly processes in volume production environments.

MAX1763EEE-T remains functionally equivalent but is obsolete and carries RoHS non-compliant status. This part may be suitable only for legacy system maintenance or low-volume applications where existing inventory is available. The tube packaging format is typical for manual assembly or small-quantity procurement.

Both parts share identical electrical specifications, pinout configuration, and thermal operating range, ensuring direct substitution at the circuit level without design modification.

Frequently Asked Questions (FAQ)

Q: Can MAX1763EEE+T directly replace MAX1763EEE-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The MAX1763EEE+T uses the same 16-SSOP package, pinout, and electrical specifications. The only differences are product status (active vs. obsolete), packaging format (tape & reel vs. tube), and RoHS compliance level. No circuit redesign is required.

Q: What is the difference between the "-T" and "+T" suffixes?

A: The "-T" suffix indicates tube packaging, while the "+T" suffix indicates tape & reel packaging. Both contain identical die and electrical performance. Tape & reel format is optimized for automated pick-and-place assembly, while tube packaging is used for manual handling or lower-volume applications.

Q: Why is MAX1763EEE-T listed as obsolete?

A: The MAX1763EEE-T has been superseded by the MAX1763EEE+T in the manufacturer's active product portfolio. The MAX1763EEE+T offers the same functionality with updated compliance certifications (ROHS3) and active production support.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts operate identically across all specified parameters: input voltage range (0.7V–5.5V), output voltage configuration (2.5V/3.3V fixed or adjustable to 5.5V), output current (2A switch), switching frequency (750kHz–1.25MHz), and operating temperature range (-40°C to 85°C).

Q: What is the impact of RoHS compliance differences?

A: The MAX1763EEE-T is RoHS non-compliant, while MAX1763EEE+T is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the MAX1763EEE+T is the required choice. Both parts maintain identical electrical and thermal characteristics.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, with packaging format considerations. Both parts use the 16-SSOP package with identical pinout and land pattern. Tape & reel (MAX1763EEE+T) is standard for automated assembly lines, while tube packaging (MAX1763EEE-T) requires manual placement or specialized handling equipment.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.
