MAX4003EUA-T RF Detector IC Equivalent & Substitute Parts

Part Overview

The MAX4003EUA-T is an RF detector integrated circuit designed for cellular applications operating across the 100MHz to 2.5GHz frequency range. This component detects RF signals in the -45dBm to 0dBm input range and is compatible with TDMA, CDMA, GPRS, and GSM standards. The device is currently classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4003EUA-T is determined by strict equivalence across the following critical parameters:

• Frequency range: 100MHz ~ 2.5GHz
• RF type compatibility: Cellular, TDMA, CDMA, GPRS, GSM
• Input signal range: -45dBm ~ 0dBm
• Supply voltage range: 2.7V ~ 5V
• Supply current: 5.9 mA
• Package configuration: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
• Surface mount capability
• RoHS3 compliance

The MAX4003EUA+T meets all specified parameters and maintains identical electrical and mechanical characteristics, differing only in packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The MAX4003EUA+T is the direct functional equivalent of the MAX4003EUA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical specifications and package dimensions. The primary distinction is product status: the MAX4003EUA-T is classified as obsolete, while the MAX4003EUA+T remains in active production.

For new designs or ongoing procurement requirements, the MAX4003EUA+T is the appropriate selection due to its active status and assured long-term availability. Both parts satisfy ROHS3 compliance and REACH requirements. The difference in packaging format (tube versus cut tape/Digi-Reel) reflects standard distribution practices and does not affect functional performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can MAX4003EUA+T replace MAX4003EUA-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The substitution is direct with no design modifications required.

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