MICRF213AYQS-TR RF Receiver Equivalent & Substitute Parts

Part Overview

The MICRF213AYQS-TR is an RF receiver module manufactured by Microchip Technology, designed for AM and OOK modulation in the 300–350 MHz frequency band. This surface-mount component operates at 3V–3.6V supply voltage with a sensitivity of -110 dBm and supports data rates up to 7.2 kbps. The device is actively produced and RoHS3 compliant, making it suitable for ISM band applications including garage door openers and remote keyless entry (RKE) systems.

Equivalent and substitute parts are identified when design requirements allow for expanded frequency coverage, improved sensitivity, or higher data rate capability while maintaining electrical and mechanical compatibility within the same package class.

Substitute Part Grouping Explanation

Substitution eligibility for the MICRF213AYQS-TR is determined by the following criteria:

Mechanical Compatibility: All substitute parts must use the 16-SSOP (0.154", 3.90 mm Width) package with surface-mount configuration to ensure PCB layout compatibility without redesign.

Electrical Compatibility: Supply voltage range (3V–3.6V) and operating temperature range (-40°C to +105°C) must be maintained or exceeded.

Functional Parameters: Substitute parts must support OOK modulation and operate within or overlap the 300–350 MHz frequency band. Improvements in sensitivity, data rate, or frequency coverage are permissible substitutions when the core frequency band is preserved or extended.

Compliance: All substitute parts must maintain ROHS3 compliance and equivalent regulatory status (REACH Unaffected, EAR99 classification).

The MICRF213AYQS and MICRF220AYQS are identified as direct substitutes based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

MICRF213AYQS (Direct Equivalent): This part is electrically and mechanically identical to the MICRF213AYQS-TR, differing only in packaging format (Tube vs. Tape & Reel). Selection is appropriate when inventory availability or packaging requirements necessitate substitution. Both parts maintain identical performance specifications and compliance certifications.

MICRF220AYQS (Manufacturer-Recommended Upgrade): This QwikRadio® series receiver extends frequency coverage to 450 MHz, provides improved sensitivity (-112.5 dBm vs. -110 dBm), and supports higher data rates (20 kbps vs. 7.2 kbps). The receiving current increases to 6 mA. This part is suitable for applications requiring expanded frequency range or enhanced performance within the same package footprint. All electrical and compliance parameters remain compatible with the original design envelope.

Both substitute parts are actively produced by Microchip Technology and maintain full ROHS3 compliance and regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can MICRF213AYQS be used as a direct replacement for MICRF213AYQS-TR?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: MICRF213AYQS-TR uses Tape & Reel packaging, while MICRF213AYQS uses Tube packaging. PCB assembly compatibility is maintained.

Q: What are the key differences between MICRF213AYQS and MICRF220AYQS?

A: The MICRF220AYQS extends frequency coverage from 300–350 MHz to 300–450 MHz, improves sensitivity from -110 dBm to -112.5 dBm, and increases maximum data rate from 7.2 kbps to 20 kbps. Receiving current increases from 3.9 mA to 6 mA. All other electrical parameters and package dimensions remain compatible.

Q: Is the MICRF220AYQS a drop-in replacement?

A: Yes, mechanically and electrically. The 16-SSOP package dimensions are identical, and supply voltage and operating temperature ranges match. However, firmware or application-level adjustments may be required to utilize the extended frequency range or higher data rate capability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MICRF213AYQS and MICRF220AYQS are both ROHS3 compliant with REACH Unaffected status and EAR99 classification, matching the compliance profile of the original part.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For direct replacement with identical performance, use MICRF213AYQS. For applications requiring extended frequency coverage or higher data rates, use MICRF220AYQS. Both are actively produced and recommended by Microchip Technology.
