MAX2511EEI-T Equivalent & Substitute Parts

Part Overview

The MAX2511EEI-T is an RF transceiver IC designed for General ISM band applications operating below 1GHz, with a frequency range of 200MHz to 440MHz. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement continuity. The part operates as a TxRx Only transceiver in a 28-SSOP surface mount package and is ROHS3 compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX2511EEI-T is based on strict electrical and mechanical parameter matching across the following criteria:

Critical Matching Parameters:

• RF transceiver type (TxRx Only)
• RF family and standard (General ISM < 1GHz)
• Frequency range (200MHz ~ 440MHz)
• Power output (-2dBm)
• Supply voltage range (2.7V ~ 5.5V)
• Current consumption (24mA receive, 26mA transmit)
• Operating temperature range (-40°C ~ 85°C)
• Package type (28-SSOP)
• Mounting type (Surface Mount)
• Compliance certifications (ROHS3, REACH Unaffected)

The MAX2511EEI+T qualifies as a direct equivalent substitute, differing only in packaging format (Tape & Reel vs. individual packaging) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The MAX2511EEI+T is the direct equivalent substitute for the MAX2511EEI-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications and package geometry. The primary distinction is product status: the MAX2511EEI-T is obsolete, while the MAX2511EEI+T maintains active status with higher inventory availability (7300 pcs vs. 1024 pcs).

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for new designs and production continuity. The packaging format difference (Tape & Reel for the substitute) is a procurement consideration rather than a functional limitation, as the component specifications remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the MAX2511EEI+T directly replace the MAX2511EEI-T in existing designs?

A: Yes. The MAX2511EEI+T is electrically and mechanically identical to the MAX2511EEI-T. All electrical parameters, frequency range, power output, current consumption, and operating temperature specifications are identical. The 28-SSOP package dimensions and pin configuration are unchanged.

Q: What is the difference between MAX2511EEI-T and MAX2511EEI+T?

A: The parts differ in packaging format and product status. The MAX2511EEI-T is supplied in individual packaging and is classified as obsolete. The MAX2511EEI+T is supplied in Tape & Reel format and maintains active product status with higher inventory availability.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance and REACH Unaffected status. MSL rating is 1 (Unlimited) for both variants.

Q: Does the Tape & Reel packaging affect component performance?

A: No. Tape & Reel packaging is a delivery and handling format only. It does not affect electrical performance, reliability, or functional characteristics of the component.

Q: What is the base product number for these parts?

A: The base product number is MAX2511, with the EEI suffix indicating the specific variant and package type designation.
