Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSA-2011-TR1G is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use SOT-143-4 surface mount packaging to ensure PCB layout compatibility without redesign.

Frequency Coverage: The substitute must support the 0Hz to 1GHz operating range or exceed it. The MAX2611EUS+T extends frequency coverage to 1.1GHz, providing full backward compatibility.

Gain Performance: The MSA-2011-TR1G specifies 15dB to 16.2dB gain. The MAX2611EUS+T provides 18.3dB gain, exceeding the original specification and maintaining signal amplification requirements.

Supply Voltage: The MSA-2011-TR1G operates from 4V to 6V. The MAX2611EUS+T operates at 5V, which falls within the original supply range and is compatible with standard single-supply designs.

RF Application Type: Both parts support ISM band applications. The MAX2611EUS+T additionally supports GPS, PCS, Set Top Box, WLAN, and WLL applications, providing broader application flexibility.

Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 ECCN classification, ensuring equivalent regulatory standing.

Parameter Comparison

Engineering Selection Recommendations

The MAX2611EUS+T is the manufacturer-recommended substitute for the obsolete MSA-2011-TR1G. Selection is based on the following engineering criteria:

Product Status: The MSA-2011-TR1G is obsolete, creating supply and long-term availability risk. The MAX2611EUS+T maintains active product status with current manufacturing and distribution support.

Regulatory Compliance: Both parts maintain equivalent REACH and ECCN classifications. The MAX2611EUS+T additionally carries ROHS3 compliance certification, meeting current environmental standards.

Package Compatibility: Identical SOT-143-4 surface mount packaging eliminates PCB redesign requirements and maintains mechanical compatibility with existing layouts.

Electrical Performance: The MAX2611EUS+T meets or exceeds all specified electrical parameters. Supply voltage compatibility at 5V falls within the original 4V to 6V range. Current consumption at 16mA is lower than the original 20mA to 40mA specification, reducing power dissipation. Gain performance at 18.3dB exceeds the original 15dB to 16.2dB specification. Extended frequency coverage to 1.1GHz provides additional operational margin beyond the original 1GHz specification.

Frequently Asked Questions (FAQ)

Q: Can the MAX2611EUS+T be used as a direct replacement for the MSA-2011-TR1G without PCB modifications?

A: Yes. Both parts use identical SOT-143-4 surface mount packaging and TO-253-4, TO-253AA case styles. Pin-to-pin compatibility and identical package footprints eliminate PCB layout changes.

Q: What are the key differences between these two parts?

A: The MAX2611EUS+T provides higher gain (18.3dB versus 15dB to 16.2dB), extended frequency coverage (1.1GHz versus 1GHz), lower current consumption (16mA versus 20mA to 40mA), and active product status versus obsolete status. The MAX2611EUS+T also carries ROHS3 compliance certification.

Q: Is the MAX2611EUS+T compatible with the original 4V to 6V supply voltage range?

A: The MAX2611EUS+T operates at 5V, which is within the original 4V to 6V supply range. Designs using 5V supply voltage are directly compatible. Designs using 4V or 6V supply voltage require verification that the MAX2611EUS+T 5V specification meets system requirements.

Q: What is the moisture sensitivity level for both parts?

A: Both the MSA-2011-TR1G and MAX2611EUS+T carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Are there any regulatory or compliance differences between these parts?

A: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The MAX2611EUS+T additionally carries ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions.

Q: What RF applications are supported by the MAX2611EUS+T?

A: The MAX2611EUS+T supports GPS, ISM, PCS, Set Top Box, WLAN, and WLL applications. The original MSA-2011-TR1G was specified for ISM applications. The MAX2611EUS+T provides equivalent ISM support with additional application flexibility.
