TDA5201XUMA1 Equivalent & Substitute Parts

Part Overview

The TDA5201XUMA1 is an RF receiver module manufactured by Infineon Technologies, designed for ASK modulation in the 310MHz to 350MHz frequency band with -107dBm sensitivity. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The TDA5201XUMA1 operates on 4.5V to 5.5V supply voltage and is housed in a 28-TSSOP surface mount package, drawing 4.8mA during reception.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TDA5201XUMA1 is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 28-TSSOP surface mount package to ensure PCB layout compatibility without redesign.

Modulation Support: The substitute must support ASK modulation as the primary protocol, ensuring signal demodulation compatibility with existing receiver designs.

Supply Voltage Range: The substitute must operate within or encompass the 4.5V to 5.5V supply voltage range to maintain compatibility with existing power distribution circuits.

Frequency Band Overlap: The substitute frequency range must include or overlap with the 310MHz to 350MHz band to support the intended application frequency.

Surface Mount Interface: Both parts must use PCB surface mount data interface and antenna connector configuration.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and equivalent MSL ratings for manufacturing and storage requirements.

The TDA5240XUMA1 qualifies as a substitute based on these criteria: it maintains the 28-TSSOP package, supports ASK modulation (with additional FSK capability), operates within the 4.5V to 5.5V supply range, includes the 300MHz to 320MHz frequency band (overlapping the lower end of the TDA5201XUMA1 range), and maintains ROHS3 compliance with equivalent MSL rating.

Parameter Comparison

Engineering Selection Recommendations

The TDA5240XUMA1 is the manufacturer-recommended substitute for the obsolete TDA5201XUMA1. Both components maintain identical package specifications (28-TSSOP) and equivalent regulatory compliance (ROHS3, MSL 3). The TDA5240XUMA1 is currently in active production status, ensuring long-term availability and supply chain stability.

The TDA5240XUMA1 provides enhanced performance characteristics: improved sensitivity (-118dBm versus -107dBm), extended operating temperature range (-40°C to 105°C versus -40°C to 85°C), and dual modulation support (ASK and FSK). The substitute maintains backward compatibility with the 4.5V to 5.5V supply voltage range required by the original design while adding optional 3V to 3.6V operation capability.

Frequency band consideration: The TDA5240XUMA1 covers 300MHz to 320MHz, which overlaps the lower portion of the TDA5201XUMA1 operating range (310MHz to 350MHz). Applications requiring operation above 320MHz in the original band will require frequency-specific evaluation.

Frequently Asked Questions (FAQ)

Q: Can the TDA5240XUMA1 directly replace the TDA5201XUMA1 without PCB modifications?

A: Yes, for applications operating in the 300MHz to 320MHz frequency band. Both components use identical 28-TSSOP packaging and surface mount configuration. No PCB layout changes are required. However, applications requiring operation above 320MHz must evaluate alternative solutions.

Q: What are the key differences in modulation capability?

A: The TDA5201XUMA1 supports ASK modulation only. The TDA5240XUMA1 supports both ASK and FSK modulation. Existing ASK-based designs will function identically with the substitute. FSK capability in the substitute is optional and does not affect ASK operation.

Q: Are there supply voltage considerations for the substitution?

A: Both parts operate within the 4.5V to 5.5V range. The TDA5240XUMA1 additionally supports 3V to 3.6V operation, providing design flexibility. Existing 5V supply circuits require no modification.

Q: How do the sensitivity specifications compare?

A: The TDA5240XUMA1 provides -118dBm sensitivity compared to the TDA5201XUMA1 at -107dBm. This represents improved receiver sensitivity, allowing detection of weaker signals. This enhancement is beneficial for range-limited applications.

Q: What is the impact of the extended operating temperature range?

A: The TDA5240XUMA1 operates to 105°C versus 85°C for the TDA5201XUMA1. This extended range provides additional thermal margin for applications in elevated ambient temperature environments. Existing designs operating within -40°C to 85°C experience no change in thermal performance.

Q: Are moisture sensitivity levels equivalent?

A: Yes, both components carry MSL 3 rating (168 hours), requiring identical handling, storage, and manufacturing precautions. No changes to component storage or assembly procedures are necessary.

Q: What packaging options are available for the TDA5240XUMA1?

A: The TDA5240XUMA1 is available in Tape & Reel (TR) packaging. The TDA5201XUMA1 packaging format is not specified in the provided data. Verify packaging requirements for your procurement and assembly processes.
