MICRF218AYQS-TR Equivalent & Substitute Parts

Part Overview

The MICRF218AYQS-TR is an RF receiver module manufactured by Microchip Technology, designed for AM modulation applications in the 300MHz to 450MHz frequency band. This surface mount component operates at supply voltages between 3V and 3.6V with a sensitivity of -108dBm and supports data rates up to 10kbps. The device is commonly used in ISM band applications including garage door openers and remote keyless entry (RKE) systems.

The MICRF218AYQS-TR is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and packaging options to support procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the MICRF218AYQS-TR are identified based on the following criteria:

Packaging Equivalence: The MICRF218AYQS (Tube packaging) is a direct functional equivalent to the MICRF218AYQS-TR (Tape & Reel packaging). Both parts share identical electrical specifications and the same 16-QSOP package footprint. The substitution is valid for applications where packaging format does not impose supply chain constraints.

Enhanced Performance Alternative: The MICRF220AYQS-TR represents an upgraded alternative within the same product family. While maintaining the same frequency range (300MHz ~ 450MHz), supply voltage (3V ~ 3.6V), and package format (16-SSOP), the MICRF220AYQS-TR offers improved sensitivity (-112.5dBm versus -108dBm), higher data rate capability (20kbps versus 10kbps), and extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C). The MICRF220AYQS-TR supports ASK and OOK modulation protocols and includes RSSI (Received Signal Strength Indicator) functionality.

Parameter Comparison

Engineering Selection Recommendations

MICRF218AYQS: This part is suitable as a direct substitute when packaging format flexibility is acceptable. Identical electrical performance and compliance certifications make this a valid alternative for procurement purposes. Both ROHS3 compliance and MSL 1 rating are maintained.

MICRF220AYQS-TR: This part is suitable when enhanced performance specifications are required or beneficial to system design. The improved sensitivity (-112.5dBm) and higher data rate (20kbps) provide operational margin for challenging RF environments. Extended operating temperature range (-40°C ~ 105°C) supports broader deployment scenarios. All parts maintain active product status and full regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can MICRF218AYQS-TR be replaced with MICRF218AYQS?

A: Yes. Both parts are electrically identical with matching frequency range, sensitivity, data rate, supply voltage, and operating temperature specifications. The difference is packaging format: MICRF218AYQS-TR uses Tape & Reel while MICRF218AYQS uses Tube packaging. PCB footprint and electrical performance are identical.

Q: What are the key differences between MICRF218AYQS-TR and MICRF220AYQS-TR?

A: The MICRF220AYQS-TR offers improved sensitivity (-112.5dBm versus -108dBm), higher maximum data rate (20kbps versus 10kbps), extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C), and support for ASK/OOK modulation in addition to AM. Receiving current increases from 5.5mA to 6mA. Both maintain the same 16-SSOP package footprint and supply voltage range.

Q: Are all substitute parts pin-compatible?

A: Yes. All listed parts use the 16-SSOP (16-QSOP) package with identical 0.154" width and 3.90mm dimensions, ensuring PCB footprint compatibility.

Q: Do all parts meet the same compliance requirements?

A: Yes. MICRF218AYQS-TR, MICRF218AYQS, and MICRF220AYQS-TR are all ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All carry MSL 1 (unlimited) moisture sensitivity rating.

Q: Which part should be selected for applications requiring extended temperature operation?

A: The MICRF220AYQS-TR supports operating temperatures from -40°C to 105°C, compared to -40°C to 85°C for the MICRF218AYQS-TR and MICRF218AYQS. Selection depends on specific application temperature requirements.
