Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX4787EXK-T is determined by the following critical parameters:

Electrical Compatibility:

• Input voltage range: 2.3V ~ 5.5V
• Output current capability: 100mA minimum
• Operating temperature range: -40°C ~ 85°C
• Current limiting function as primary control mechanism

Mechanical Compatibility:

• Package type: SC-70-5 (5-TSSOP, SOT-353)
• Surface mount configuration
• Pin-compatible footprint

Regulatory & Compliance:

• RoHS3 compliance
• MSL Level 1 rating
• REACH unaffected status

The substitute parts are grouped into two categories:

Parametric Equivalent: MAX4787EXK+T (identical electrical specifications, packaging variant only)

Functional Equivalents with Enhanced Specifications: FPF2000, FPF2002, FPF2003, FPF2004 (power switch/driver devices with current limiting, higher current ratings, and active product status)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): MAX4787EXK+T is the direct parametric equivalent with identical electrical and functional specifications. This part maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring long-term availability and supply chain stability. The only difference is packaging format (Tape & Reel vs. standard packaging), which does not affect electrical performance or PCB compatibility.

For Functional Substitution: FPF2004 (Fairchild Semiconductor) provides the closest functional match among alternative manufacturers, offering 100mA output current capability identical to the MAX4787EXK-T. This part maintains active product status and SC-70-5 package compatibility. FPF2004 implements power switch/driver architecture with integrated current limiting, over-temperature protection, and UVLO fault protection.

FPF2003 (onsemi) and FPF2002 (Fairchild Semiconductor) are suitable for applications where 50mA output current is sufficient. Both maintain active product status and include current limiting, over-temperature, and UVLO protection features.

FPF2000 (onsemi) is functionally equivalent to FPF2003 but carries obsolete product status, making it less suitable for new designs or long-term production commitments.

All substitute parts maintain SC-70-5 package compatibility, surface mount configuration, and -40°C to 85°C operating temperature range required for direct PCB substitution.

Frequently Asked Questions (FAQ)

Q: Can MAX4787EXK+T be used as a direct replacement for MAX4787EXK-T? A: Yes. MAX4787EXK+T is a parametric equivalent with identical electrical specifications, input/output voltage ranges, current rating, and operating temperature. The difference is packaging format (Tape & Reel). Both are pin-compatible and functionally interchangeable on the PCB.

Q: What is the key difference between MAX4787EXK-T and FPF2004? A: Both devices provide 100mA current limiting in SC-70-5 packages with identical operating temperature ranges. The MAX4787EXK-T is a dedicated current limiting regulator, while FPF2004 is a power switch/driver with integrated current limiting. FPF2004 offers active product status and additional protection features (auto restart, status flag). Input voltage range for FPF2004 extends to 1.8V minimum versus 2.3V for MAX4787EXK-T.

Q: Can FPF2003 or FPF2002 replace MAX4787EXK-T in all applications? A: FPF2003 and FPF2002 are suitable only for applications requiring maximum 50mA output current. Both maintain SC-70-5 package compatibility and identical operating temperature range. If your application requires the full 100mA capability of MAX4787EXK-T, use FPF2004 instead.

Q: Are all substitute parts RoHS3 compliant? A: MAX4787EXK+T, FPF2000, and FPF2003 are explicitly RoHS3 compliant. FPF2002 and FPF2004 do not specify RoHS status in available documentation. Verify RoHS compliance requirements with your supply chain or manufacturer if this is a critical specification for your application.

Q: What is the MSL rating for substitute parts? A: MAX4787EXK+T, FPF2000, and FPF2003 are rated MSL Level 1 (Unlimited moisture sensitivity). FPF2002 and FPF2004 do not specify MSL ratings. Confirm MSL requirements with your manufacturing process before selection.

Q: Are all substitute parts available in SC-70-5 package? A: Yes. All listed substitute parts (MAX4787EXK+T, FPF2000, FPF2002, FPF2003, FPF2004) are available in 5-TSSOP/SC-70-5/SOT-353 package configuration, ensuring PCB footprint compatibility without layout modifications.
