Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MICRF221AYQS-TR are identified based on strict equivalence across the following critical parameters:

• Frequency range: 850MHz ~ 950MHz
• Sensitivity: -109dBm
• Data rate capability: 10kbps maximum
• Modulation support: ASK and OOK
• Supply voltage: 3V ~ 3.6V
• Receiving current: 9.3mA
• Operating temperature range: -40°C ~ 85°C
• Package type: 16-SSOP with 3.90mm width
• Mounting technology: Surface Mount

The MICRF221AYQS represents a direct substitute, differing only in packaging format (Tube versus Cut Tape & Digi-Reel). Both parts share identical electrical characteristics, mechanical dimensions, and functional specifications, allowing interchangeability in circuit design while accommodating different procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

Both the MICRF221AYQS-TR and MICRF221AYQS are active production parts from Microchip Technology with identical electrical and mechanical specifications. Selection between these parts depends on procurement and assembly requirements rather than functional performance.

The MICRF221AYQS-TR in Cut Tape & Digi-Reel packaging is suitable for high-volume automated assembly operations and tape-and-reel feeding systems. The MICRF221AYQS in Tube packaging accommodates manual assembly processes, lower-volume production runs, or alternative handling workflows.

Both parts maintain full compliance with RoHS3 regulations and REACH requirements, ensuring regulatory compatibility across applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling. Selection should be based on assembly equipment compatibility and supply chain logistics rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can MICRF221AYQS be used as a direct replacement for MICRF221AYQS-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Cut Tape & Digi-Reel versus Tube. Substitution is valid for circuit design and functional performance.

Q: What determines compatibility between these RF receiver parts?

A: Compatibility is determined by matching frequency range (850-950MHz), sensitivity (-109dBm), data rate (10kbps), modulation type (ASK/OOK), supply voltage (3-3.6V), operating temperature range (-40 to 85°C), and package dimensions (16-SSOP, 3.90mm width).

Q: Does packaging format affect electrical performance?

A: No. Cut Tape & Digi-Reel and Tube packaging formats contain identical components with identical electrical characteristics. Packaging differences affect only procurement, storage, and assembly handling.

Q: Are there any compliance differences between substitute parts?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited). Regulatory and environmental certifications are equivalent.

Q: Which packaging format should be selected for automated assembly?

A: Cut Tape & Digi-Reel packaging (MICRF221AYQS-TR) is designed for automated tape-and-reel feeding systems. Tube packaging (MICRF221AYQS) is suitable for manual assembly or alternative handling processes.

Q: Can these parts be mixed in the same production batch?

A: Yes, provided assembly equipment can accommodate both packaging formats. Both parts are functionally identical and will perform identically in the circuit.
