AMRRQ3-433 RF Receiver Module: Equivalent & Substitute Parts

Part Overview

The AMRRQ3-433 is an RF receiver module manufactured by RF Solutions operating at 433MHz with AM modulation, designed for AM remote control applications. This through-hole module provides -107dBm sensitivity at a maximum data rate of 4.8kbps and operates on a 5V supply across the temperature range of -25°C to 85°C.

The AMRRQ3-433 is classified as obsolete. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design revisions require components with improved specifications or active product status. The AM-RRQ3-433P serves as a direct substitute offering enhanced sensitivity and extended operating temperature range while maintaining core 433MHz AM receiver functionality.

Key Parameters

Substitute Part Grouping Explanation

The AM-RRQ3-433P qualifies as a direct substitute for the AMRRQ3-433 based on the following alignment of critical parameters:

Matching Parameters:

• Frequency: 433MHz (identical RF operating frequency)
• Modulation: AM (same demodulation protocol)
• Mounting Type: Through Hole (compatible PCB integration)
• Package Category: Module (same physical form factor classification)
• Manufacturer: RF Solutions (same original equipment manufacturer)

Enhanced Parameters:

• Sensitivity: -108dBm (1dB improvement over -107dBm)
• Operating Temperature: -40°C to 85°C (extended lower temperature limit from -25°C)
• Voltage Supply: 3.3V to 8V (wider supply voltage range accommodating 5V operation)
• Product Status: Active (current production availability)
• RoHS Compliance: ROHS3 Compliant (improved environmental compliance versus non-compliant status)

The AM-RRQ3-433P maintains functional equivalence while offering superior environmental specifications and active product status, making it suitable for direct replacement in applications currently using the AMRRQ3-433.

Parameter Comparison

Engineering Selection Recommendations

Substitution Viability:

The AM-RRQ3-433P is suitable as a direct replacement for the AMRRQ3-433 in applications requiring 433MHz AM receiver functionality. The substitute maintains identical RF operating frequency and modulation protocol while offering measurable improvements in receiver sensitivity and extended environmental operating range.

Product Status Consideration:

The AMRRQ3-433 is classified as obsolete, indicating discontinued production and limited remaining inventory. The AM-RRQ3-433P maintains active product status with RF Solutions, ensuring long-term availability and supply chain reliability for new designs or production continuations.

Compliance and Certification:

The AM-RRQ3-433P achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. The AMRRQ3-433 is RoHS non-compliant, which may present regulatory constraints in certain markets or applications subject to environmental directives.

Electrical Compatibility:

The substitute operates across a 3.3V to 8V supply voltage range, encompassing the 5V requirement of the original part. This wider supply tolerance provides design flexibility and may accommodate variations in system power distribution.

Thermal Performance:

The AM-RRQ3-433P extends the lower operating temperature limit to -40°C compared to the AMRRQ3-433 at -25°C, enabling deployment in more demanding environmental conditions while maintaining the upper limit of 85°C.

Frequently Asked Questions (FAQ)

Q: Can the AM-RRQ3-433P directly replace the AMRRQ3-433 without PCB modifications?

A: The AM-RRQ3-433P is a through-hole module with 9 leads in a 15-SIP package configuration. Direct replacement requires verification that the PCB footprint accommodates the 15-SIP lead pattern. Pin-to-pin compatibility must be confirmed against the original AMRRQ3-433 through-hole layout before installation.

Q: What is the significance of the -108dBm sensitivity specification on the AM-RRQ3-433P compared to -107dBm on the AMRRQ3-433?

A: The -108dBm sensitivity represents a 1dB improvement in receiver detection capability. Lower dBm values indicate greater sensitivity to weak incoming signals. This enhancement allows the substitute to detect signals at slightly lower power levels, improving reception range and reliability in low-signal environments.

Q: Does the wider supply voltage range (3.3V to 8V) on the AM-RRQ3-433P affect circuit design?

A: The substitute's 3.3V to 8V supply range encompasses the 5V requirement of the original AMRRQ3-433. Existing 5V power supply designs require no modification. The wider tolerance provides additional design margin and may reduce sensitivity to supply voltage variations in the system.

Q: Why is RoHS compliance important for the AM-RRQ3-433P?

A: ROHS3 compliance indicates the substitute meets current European Union Restriction of Hazardous Substances directives. The original AMRRQ3-433 is RoHS non-compliant, which may restrict its use in applications subject to environmental regulations or customer requirements mandating compliant components.

Q: Is the extended temperature range (-40°C to 85°C) of the AM-RRQ3-433P necessary for my application?

A: The extended lower temperature limit to -40°C is beneficial for applications operating in cold environments or requiring broader thermal performance margins. If your application operates within the original -25°C to 85°C range, the substitute remains fully functional. The extended range provides additional operational headroom without penalty.

Q: What information is not specified for the AM-RRQ3-433P that was provided for the AMRRQ3-433?

A: The maximum data rate specification is not provided for the AM-RRQ3-433P. The original AMRRQ3-433 specifies 4.8kbps maximum data rate. For applications with specific data rate requirements, this parameter should be confirmed with RF Solutions technical documentation or the component supplier.

Q: Are there any mechanical considerations when substituting the AM-RRQ3-433P?

A: The AM-RRQ3-433P is specified as a 15-SIP Module with 9 leads, while the original AMRRQ3-433 is a through-hole module. The physical lead count and spacing must be verified against your PCB footprint design. Mechanical compatibility requires confirmation that the 15-SIP package dimensions and lead pitch align with the original board layout.
