MAX749CSA Equivalent & Substitute Parts

Part Overview

The MAX749CSA is an LCD Display Power Management IC (PMIC) manufactured by Analog Devices Inc./Maxim Integrated in an 8-SOIC surface mount package. This component functions as an LCD bias supply with digital adjustment capability, designed for LCD display applications requiring regulated voltage generation from a 2V to 6V supply input.

The MAX749CSA is classified as obsolete. Identifying suitable substitute components is necessary to support ongoing production requirements, design updates, and inventory management for systems utilizing this LCD bias supply topology.

Substitute Part Grouping Explanation

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

• Voltage supply range: 2V ~ 6V
• Supply current specification: 60µA
• Operating temperature range: 0°C ~ 70°C
• Package configuration: 8-SOIC (0.154", 3.90mm Width)
• Mounting technology: Surface Mount
• Moisture sensitivity classification: MSL 1

The MAX749CSA+ meets all substitution criteria. Both components share identical electrical specifications, package geometry, and thermal operating range. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX749CSA+ is the direct substitute for the MAX749CSA. Both components are electrically and mechanically identical across all specified parameters. Selection between these parts should be based on the following factors:

For new designs or production requiring regulatory compliance, the MAX749CSA+ is the appropriate choice due to its Active product status and ROHS3 compliance certification. The MAX749CSA, being obsolete and RoHS non-compliant, is suitable only for legacy system maintenance or applications where compliance requirements do not apply.

Both components maintain identical supply current characteristics (60µA), voltage operating range (2V ~ 6V), and thermal specifications (0°C ~ 70°C), ensuring functional interchangeability within the 8-SOIC package footprint.

Frequently Asked Questions (FAQ)

Q: Can the MAX749CSA+ be used as a direct replacement for the MAX749CSA in existing designs?

A: Yes. The MAX749CSA+ is electrically and mechanically equivalent to the MAX749CSA. Both components share identical voltage supply range (2V ~ 6V), supply current (60µA), operating temperature range (0°C ~ 70°C), and 8-SOIC package configuration. No circuit modifications are required for substitution.

Q: What is the primary difference between MAX749CSA and MAX749CSA+?

A: The MAX749CSA+ is the active production variant with ROHS3 compliance certification. The MAX749CSA is classified as obsolete and is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or mounting differences between these parts?

A: Both components use the same 8-SOIC (0.154", 3.90mm Width) surface mount package. The MAX749CSA+ is supplied in Tube packaging, while the MAX749CSA packaging format is not specified. PCB footprint and mounting procedures are identical.

Q: What is the moisture sensitivity level for these components?

A: Both the MAX749CSA and MAX749CSA+ are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Is the MAX749CSA+ suitable for new product designs?

A: Yes. The MAX749CSA+ is the recommended choice for new designs due to its Active product status and ROHS3 compliance. It meets all electrical and mechanical requirements for LCD display bias supply applications within the specified voltage and temperature ranges.
