Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX2650EUS-T is determined by strict equivalence across the following critical parameters:

• Frequency range: 0Hz ~ 1GHz
• P1dB: -1dBm
• Noise Figure: 3.9dB
• Supply voltage: 4.5V ~ 5.5V
• Supply current: 18mA
• Package: SOT-143-4
• RF application type: Cellular, GPS, W-LAN, WLLG

Two substitute parts meet these criteria with variations in product status and gain specification. The MAX2650EUS+ variant shows a gain increase to 21dB while maintaining all other electrical parameters. The MAX2650EUS+T maintains identical electrical specifications to the original part and is available in active production status with higher inventory levels.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete MAX2650EUS-T, the MAX2650EUS+T is the primary recommendation. This part maintains identical electrical specifications including gain (18.3dB), noise figure (3.9dB), and all supply parameters. The MAX2650EUS+T is in active production status with significantly higher inventory availability (22028 units), ensuring long-term procurement reliability. Both substitute parts maintain ROHS3 compliance and identical moisture sensitivity ratings.

The MAX2650EUS+ variant is available as an alternative with increased gain (21dB) while preserving all other critical parameters. Selection between MAX2650EUS+ and MAX2650EUS+T depends on whether the 2.7dB gain increase is compatible with circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX2650EUS+ be used as a direct replacement for MAX2650EUS-T?

A: Yes, with circuit design consideration. The MAX2650EUS+ maintains all critical electrical parameters (frequency range, P1dB, noise figure, supply voltage/current) and package specifications. The gain difference of 2.7dB (21dB vs 18.3dB) must be evaluated for impact on circuit performance and signal levels.

Q: Why is MAX2650EUS+T preferred over MAX2650EUS+?

A: The MAX2650EUS+T provides exact electrical equivalence to the original MAX2650EUS-T with identical gain (18.3dB) and is available in significantly higher quantities (22028 units vs 802 units), supporting long-term supply chain stability.

Q: Are all three parts identical in package and mounting?

A: Yes. All three parts use the SOT-143-4 package (TO-253-4, TO-253AA) with surface mount technology, ensuring PCB layout and assembly compatibility.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. Both MAX2650EUS+ and MAX2650EUS+T are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original part's environmental and regulatory status.

Q: What is the primary reason to transition from MAX2650EUS-T?

A: The original part is classified as obsolete. The active production status of MAX2650EUS+T ensures continued availability, technical support, and compliance with current manufacturing standards.
