AM-HRR3-433 RF Receiver: Equivalent & Substitute Parts

Part Overview

The AM-HRR3-433 is an RF receiver module manufactured by RF Solutions, designed for amplitude modulation (AM) reception at -105dBm sensitivity. This component operates within the 4.5V to 5.5V supply voltage range and is housed in a 15-SIP through-hole package configuration.

The AM-HRR3-433 has reached obsolete product status. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and new design requirements where this receiver module is specified or functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM-HRR3-433 is evaluated based on the following critical parameters:

Modulation Protocol Compatibility: The substitute component must support AM modulation to maintain functional equivalence in reception capability.

Receiver Sensitivity: The substitute must achieve sensitivity performance within acceptable operational margins. The AM-HRR3-433 operates at -105dBm; substitute components with equal or superior (lower dBm value) sensitivity are considered compatible.

Supply Voltage Range: The substitute must operate within or encompass the original 4.5V to 5.5V supply voltage specification. Substitutes with wider voltage ranges that include this window are acceptable.

Mounting Configuration: Through-hole mounting type is required to maintain mechanical compatibility with existing PCB layouts and assembly processes.

Operating Temperature Range: The substitute must support the original -25°C to 80°C operating window or provide an extended range that encompasses these limits.

Package Type: The 15-SIP package configuration is the baseline mechanical requirement for direct substitution.

The AM-RRQ3-433P is identified as a substitute based on shared AM modulation protocol, compatible through-hole mounting, and overlapping operational parameters.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The AM-HRR3-433 is classified as obsolete. The AM-RRQ3-433P maintains active product status with RF Solutions, ensuring ongoing availability and manufacturing support.

Compliance and Certification: The AM-RRQ3-433P carries ROHS3 compliance certification and EAR99 ECCN classification, meeting current regulatory requirements for electronic component distribution and use.

Voltage Supply Compatibility: The AM-RRQ3-433P operates across a 3.3V to 8V supply range, which encompasses the original 4.5V to 5.5V specification window. This extended range provides design flexibility for applications requiring the original voltage parameters.

Sensitivity Performance: The AM-RRQ3-433P achieves -108dBm sensitivity, representing a 3dBm improvement over the AM-HRR3-433 baseline of -105dBm. This enhanced sensitivity supports equivalent or superior reception performance.

Operating Temperature Range: The AM-RRQ3-433P extends the operating temperature window to -40°C to 85°C, encompassing and exceeding the original -25°C to 80°C specification.

Current Consumption: The AM-RRQ3-433P draws 6mA during reception, compared to 2.5mA for the original part. Power budget analysis is required for applications with strict current constraints.

Frequently Asked Questions (FAQ)

Q: Can the AM-RRQ3-433P directly replace the AM-HRR3-433 in existing designs?

A: The AM-RRQ3-433P is mechanically and functionally compatible as a substitute. Both components use through-hole mounting in 15-SIP package configurations and support AM modulation. The substitute operates within the original supply voltage window (4.5V to 5.5V falls within the 3.3V to 8V range of the AM-RRQ3-433P). Verification of increased current consumption (6mA vs. 2.5mA) against circuit power budgets is required before implementation.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), receiving current (2.5mA vs. 6mA), sensitivity performance (-105dBm vs. -108dBm), and operating temperature range (-25°C to 80°C vs. -40°C to 85°C). The AM-RRQ3-433P provides superior sensitivity and extended temperature operation at the cost of increased current draw.

Q: Are there any package compatibility concerns?

A: Both parts use 15-SIP through-hole packages. The AM-RRQ3-433P is specified as a 15-SIP Module with 9 leads, while the AM-HRR3-433 uses a standard 15-SIP configuration. PCB layout verification is recommended to confirm lead-to-pad alignment and spacing compatibility.

Q: What compliance certifications apply to the substitute part?

A: The AM-RRQ3-433P is ROHS3 compliant and classified under EAR99 for export control purposes. The original AM-HRR3-433 compliance status is not specified in available documentation.

Q: How does the sensitivity difference affect system performance?

A: The AM-RRQ3-433P achieves -108dBm sensitivity compared to -105dBm for the original part. This 3dBm improvement represents enhanced reception capability and may extend operational range in weak-signal environments. System performance will not degrade due to this specification difference.
