Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX1677EEE-T is determined by strict equivalence across the following critical parameters:

• Identical boost converter topology with step-up function
• Matching dual positive output configuration
• Input voltage range: 0.7V to 5.5V
• Output voltage options: 1.25V, 2.5V (3.3V)
• Output current capability: 350mA (Switch)
• Switching frequency: 300kHz
• Synchronous rectifier implementation
• Operating temperature range: -40°C to 85°C
• Package compatibility: 16-SSOP (0.154", 3.90mm Width)
• Surface mount configuration

The MAX1677EEE+T qualifies as a direct substitute based on identical electrical specifications and mechanical packaging. The primary distinction is packaging format (Tape & Reel versus individual unit) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The MAX1677EEE+T is a direct functional equivalent to the MAX1677EEE-T with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Product Status: The MAX1677EEE+T carries Active product status, ensuring continued manufacturer support and availability. The MAX1677EEE-T is classified as Obsolete, limiting future procurement options.

Compliance: The MAX1677EEE+T meets ROHS3 compliance requirements, while the MAX1677EEE-T is RoHS non-compliant. For applications subject to RoHS regulations, the MAX1677EEE+T is the required selection.

Packaging Format: The MAX1677EEE+T is supplied in Tape & Reel format, suitable for automated assembly processes. The MAX1677EEE-T is supplied as individual units. Packaging selection depends on production volume and assembly methodology.

Inventory Availability: The MAX1677EEE+T demonstrates higher current inventory levels (3900 Pcs) compared to the MAX1677EEE-T (1035 Pcs), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Are the MAX1677EEE-T and MAX1677EEE+T electrically identical?

A: Yes. Both parts share identical electrical specifications including input voltage range (0.7V to 5.5V), output voltage options (1.25V, 2.5V, 3.3V), output current (350mA), switching frequency (300kHz), and operating temperature range (-40°C to 85°C).

Q: What is the difference between these two part numbers?

A: The primary differences are product status (Obsolete versus Active), RoHS compliance (non-compliant versus ROHS3 Compliant), and packaging format (individual unit versus Tape & Reel). Electrical performance and package dimensions are identical.

Q: Can I use MAX1677EEE+T as a direct replacement for MAX1677EEE-T in existing designs?

A: Yes. The MAX1677EEE+T is a direct substitute with identical pin configuration, package dimensions (16-SSOP, 0.154", 3.90mm Width), and electrical characteristics. No circuit modifications are required.

Q: Why should I choose the MAX1677EEE+T over the MAX1677EEE-T?

A: The MAX1677EEE+T is recommended for new designs and ongoing production due to Active product status, ROHS3 compliance, and superior inventory availability. The MAX1677EEE-T, being Obsolete, presents supply chain risk.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-40°C to 85°C) and deliver equivalent performance specifications.

Q: What packaging considerations apply to these parts?

A: The MAX1677EEE-T is supplied as individual units suitable for small-volume or prototype applications. The MAX1677EEE+T is supplied in Tape & Reel format, optimized for high-volume automated assembly. Both use identical 16-SSOP surface mount packages.
