Key Parameters

Substitute Part Grouping Explanation

Substitution of the FM-RRFQ2-433RP is determined by strict equivalence across the following critical parameters:

Frequency Matching: Both the main part and substitute must operate at 433.92MHz to maintain compatibility with existing RF infrastructure and regulatory compliance.

Sensitivity and Data Rate: The -103dBm sensitivity and 9.6kbps maximum data rate define the receiver's performance envelope. Substitute parts must maintain these specifications to ensure signal detection and data throughput requirements are met.

Modulation Protocol: FM modulation must be preserved across all substitute parts to ensure compatibility with transmitter systems and signal processing circuits.

Electrical Characteristics: Supply voltage range (4.5V ~ 5.5V), receiving current (5.7mA), and operating temperature range (-25°C ~ 80°C) must be identical to ensure direct integration into existing power distribution and thermal management designs.

Physical Form Factor: Through-hole mounting and module package type must be maintained for mechanical compatibility with PCB layouts and assembly processes.

The FM-RRFQ1-433P meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The FM-RRFQ1-433P is the qualified substitute for the obsolete FM-RRFQ2-433RP. Both parts are manufactured by RF Solutions and maintain identical electrical, RF, and mechanical specifications across all critical parameters.

Product Status Consideration: The FM-RRFQ2-433RP is classified as obsolete, while the FM-RRFQ1-433P maintains active product status. This distinction is significant for long-term supply chain planning and component availability.

Compliance Advantage: The FM-RRFQ1-433P achieves ROHS3 compliance, whereas the FM-RRFQ2-433RP is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the FM-RRFQ1-433P provides regulatory alignment.

Functional Equivalence: All RF performance parameters, electrical characteristics, and physical form factors are identical between the two parts, ensuring direct functional substitution without circuit redesign or performance degradation.
