Substitute Part Grouping Explanation

Substitution of the MAX845EUA-T is determined by strict equivalence across the following parameters:

• Voltage Supply Range: 2.5V ~ 6V
• Supply Current: 1.1mA
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
• Supplier Device Package: 8-uMAX/uSOP
• Functional Application: Transformer Driver

The substitute part MAX845EUA+T meets all electrical and mechanical requirements for direct substitution. Both parts share identical base product number (MAX845), supply voltage specifications, current consumption, temperature operating range, and physical packaging dimensions.

Parameter Comparison

Engineering Selection Recommendations

The MAX845EUA+T is the direct substitute for the obsolete MAX845EUA-T. Both parts are electrically and mechanically identical across all specified parameters. The substitute part offers the following advantages:

• Active product status ensures ongoing availability and manufacturing support
• ROHS3 compliance meets current environmental and regulatory requirements
• Improved moisture sensitivity level (MSL 1 vs. MSL 3) provides superior handling and storage characteristics
• Identical electrical performance and pinout enable direct replacement without circuit modification

Selection of MAX845EUA+T is appropriate for new designs and replacement applications requiring transformer driver functionality within the specified voltage and temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can MAX845EUA+T directly replace MAX845EUA-T in existing designs?

A: Yes. Both parts share identical electrical specifications (2.5V ~ 6V supply, 1.1mA current, -40°C ~ 85°C operating range) and physical packaging (8-uMAX/uSOP). No circuit modifications are required.

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

A: The primary differences are product status and compliance certifications. MAX845EUA-T is obsolete, while MAX845EUA+T is active. MAX845EUA+T includes ROHS3 compliance and improved moisture sensitivity rating (MSL 1 vs. MSL 3).

Q: Are the packages physically identical?

A: Yes. Both parts use 8-TSSOP, 8-MSOP packaging with 0.118" width (3.00mm). Pin configuration and footprint are identical.

Q: What is the moisture sensitivity level difference?

A: MAX845EUA-T has MSL 3 (168-hour floor life), while MAX845EUA+T has MSL 1 (unlimited floor life). MSL 1 indicates superior moisture resistance and more flexible storage and handling conditions.

Q: Is RoHS compliance a functional difference?

A: No. RoHS compliance is a manufacturing and environmental standard, not a functional specification. ROHS3 compliance of MAX845EUA+T indicates adherence to current environmental regulations.
