MAX749CSA-T Equivalent & Substitute Parts

Part Overview

The MAX749CSA-T is a LCD Display Power Management IC (PMIC) manufactured by Analog Devices Inc./Maxim Integrated in an 8-SOIC surface mount package. This component functions as a bias supply controller for LCD displays with adjustable output voltage. The part is currently classified as obsolete, which necessitates identification of equivalent substitute components for ongoing design support and production continuity. Substitute parts must maintain identical electrical specifications and package compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX749CSA-T is determined by strict equivalence across the following critical parameters:

• Package / Case: Must be 8-SOIC (0.154", 3.90mm Width) for PCB footprint compatibility
• Voltage - Supply: Must support 2V ~ 6V input range
• Current - Supply: Must maintain 60µA specification
• Operating Temperature: Must cover 0°C ~ 70°C range
• Mounting Type: Must be Surface Mount
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

Only components meeting all these parameters are classified as direct substitutes. The base product number MAX749 identifies the functional family; however, packaging and suffix designations determine actual interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The MAX749CSA+T is a direct functional equivalent to the MAX749CSA-T. Both components share identical electrical parameters, package specifications, and compliance certifications. The primary distinction is product status: the MAX749CSA-T is obsolete while the MAX749CSA+T maintains active production status. The MAX749CSA+T is available in higher inventory quantities (18,167 pieces) compared to the MAX749CSA-T (2,274 pieces), providing improved supply chain reliability. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in equivalent applications. The packaging designation difference (CT & Digi-Reel® for the substitute) reflects distribution format only and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX749CSA+T directly replace MAX749CSA-T on existing PCBs?

A: Yes. Both components use identical 8-SOIC package geometry (0.154", 3.90mm width) and share the same pinout. No PCB modifications are required for substitution.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts operate within 2V ~ 6V supply voltage range, maintain 60µA supply current, and support 0°C ~ 70°C operating temperature. Functional performance is equivalent.

Q: What is the difference between the part number suffixes (-T vs +T)?

A: The suffix designates packaging and distribution format. The "-T" indicates tape packaging, while "+T" indicates cut tape and Digi-Reel® packaging. Both formats contain identical die and electrical specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both MAX749CSA-T and MAX749CSA+T are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), meeting current environmental and regulatory requirements.

Q: Why is the MAX749CSA-T listed as obsolete?

A: Product obsolescence reflects manufacturer lifecycle decisions. The MAX749CSA+T remains in active production and serves as the current equivalent for new designs and production continuity.

Q: Are there inventory considerations when selecting between these parts?

A: Yes. The MAX749CSA+T has significantly higher inventory availability (18,167 pieces) versus the MAX749CSA-T (2,274 pieces), making it the preferred choice for supply chain stability and lead time assurance.
