AM-HRR3-315 RF Receiver Equivalent & Substitute Parts

Part Overview

The AM-HRR3-315 is an RF receiver module manufactured by RF Solutions, designed for 315MHz AM modulation applications. This component operates at -105dBm sensitivity with a 15-SIP through-hole package configuration. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support, maintenance, and new design implementations where legacy component replacement is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM-HRR3-315 is determined by the following critical parameters:

Primary Substitution Criteria:

• Operating frequency: 315MHz
• Modulation type: AM
• Mounting technology: Through Hole
• Package category: SIP (Single In-line Package)
• Application scope: General Purpose RF reception

The substitute part 1097 (Adafruit Industries LLC) meets the core functional requirements of 315MHz frequency operation and through-hole mounting. Both components are designed for general-purpose RF receiver applications at the same frequency band. The 1097 features an integrated helical antenna, whereas the AM-HRR3-315 operates as a discrete receiver module. The package form factor differs (7-SIP versus 15-SIP), which affects PCB layout and pin configuration but does not prevent functional substitution in applications where physical space and pin mapping can be accommodated.

Engineering Selection Recommendations

Product Status Consideration: The AM-HRR3-315 is classified as obsolete. The substitute part 1097 maintains active product status with current manufacturing support from Adafruit Industries LLC. For applications requiring long-term component availability and technical support, the 1097 represents a viable alternative.

Compliance and Certification: The 1097 is ROHS3 compliant and carries EAR99 export classification. The primary part AM-HRR3-315 does not provide RoHS compliance documentation. For applications subject to environmental or export regulations, the 1097 meets current regulatory requirements.

Functional Alignment: Both components operate at 315MHz and support through-hole mounting for general-purpose RF reception. The frequency alignment is exact. The package form factor difference (15-SIP to 7-SIP) requires PCB redesign and pin mapping verification during implementation.

Documentation Limitations: The substitute part 1097 does not provide complete electrical specifications (sensitivity, current consumption, voltage supply range, operating temperature range, modulation protocol). Direct electrical parameter comparison cannot be performed with available data. Applications requiring specific performance metrics should obtain complete datasheets from the manufacturer before final selection.

Frequently Asked Questions (FAQ)

Q: Can the 1097 directly replace the AM-HRR3-315 without PCB modifications?

A: No. The AM-HRR3-315 uses a 15-SIP package while the 1097 uses a 7-SIP package. Different pin counts require PCB layout redesign and pin mapping verification. Through-hole mounting technology is common to both, but physical footprint and pin configuration differ.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on: operating frequency (315MHz), modulation type (AM), mounting technology (through-hole), package category (SIP), and application scope (general purpose). Both the AM-HRR3-315 and 1097 satisfy these core criteria.

Q: Why are some electrical parameters missing for the 1097?

A: The substitute part 1097 datasheet provided does not include sensitivity, current consumption, voltage supply range, operating temperature range, or modulation protocol specifications. These parameters must be obtained from the manufacturer's complete technical documentation.

Q: Is the 1097 suitable for applications requiring -105dBm sensitivity?

A: The 1097 sensitivity specification is not provided in available documentation. Confirmation of sensitivity performance must be obtained from Adafruit Industries LLC before selecting this component for applications with specific sensitivity requirements.

Q: What is the significance of the integrated helical antenna in the 1097?

A: The 1097 includes an integrated helical antenna, whereas the AM-HRR3-315 antenna configuration is not documented. This difference affects circuit design, PCB layout, and external antenna requirements. Applications using external antennas may require design modifications.

Q: Does the ROHS3 compliance of the 1097 affect compatibility?

A: ROHS3 compliance indicates the 1097 meets current environmental standards for hazardous substance restrictions. This is a regulatory advantage for new designs and applications subject to environmental regulations. The AM-HRR3-315 does not provide RoHS compliance documentation.

Q: Can I use the 1097 in legacy systems designed for the AM-HRR3-315?

A: Substitution requires verification of pin mapping, electrical specifications, and physical fit. The different package sizes necessitate PCB modifications. Complete electrical parameter comparison should be performed using manufacturer datasheets before implementation in legacy systems.
