RF Solutions 110C1-315AR2 Equivalent & Substitute Parts

Part Overview

The RF Solutions 110C1-315AR2 is an AM 315MHz RF transmitter module designed for handheld applications with a single switch interface. This component operates as a KeeLoq-compatible transmitter with a 50-meter transmission range and 10mW output power at 12V supply voltage. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations where 315MHz AM transmission capability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 110C1-315AR2 is constrained by the following critical parameters:

Frequency Compatibility: The 315MHz operating frequency is region-specific and regulated. Substitutes must operate at the same frequency band to maintain regulatory compliance and system interoperability.

Modulation Type: AM modulation is specified for this application. Substitutes must support AM modulation as a minimum requirement.

Supply Voltage: The 12V supply voltage requirement must be matched or the substitute must operate within compatible voltage ranges.

Base Product Series: Both the main part and substitute share the 110C1 base product number, indicating they belong to the same RF Solutions transmitter family and are designed for cross-compatibility within the series.

Manufacturer: RF Solutions maintains consistent electrical and mechanical interfaces within the 110C1 series, ensuring pin compatibility and form factor alignment.

The substitute part 110C1-433A shares the same base product number and manufacturer, but operates at 433MHz with AM/FM modulation capability. This represents a frequency variant within the same product family rather than a direct electrical equivalent.

Parameter Comparison

Engineering Selection Recommendations

For Direct 315MHz Replacement: The 110C1-315AR2 is obsolete. If 315MHz operation is mandatory for regulatory or system compatibility reasons, RF Solutions 110C1 series inventory should be verified for any remaining 315MHz variants. The substitute 110C1-433A operates at a different frequency and is not suitable for applications requiring 315MHz transmission.

For Frequency-Flexible Applications: The 110C1-433A is an active product with ROHS3 compliance and EAR99 classification, offering improved regulatory status compared to the obsolete 110C1-315AR2. This substitute is applicable only when 433MHz operation is acceptable within the target application and regulatory environment.

Voltage Compatibility: Both parts operate at 12V supply voltage, ensuring power supply compatibility within the same system architecture.

Compliance Considerations: The 110C1-433A provides superior compliance posture with ROHS3 certification, whereas the 110C1-315AR2 is not subject to RoHS requirements due to its obsolete status and regulatory classification.

Frequently Asked Questions (FAQ)

Q: Can the 110C1-433A directly replace the 110C1-315AR2 in an existing design?

A: No. The 110C1-433A operates at 433MHz while the 110C1-315AR2 operates at 315MHz. Frequency substitution requires system-level validation including receiver compatibility, regulatory approval for the target market, and antenna tuning adjustments. These are not plug-and-play substitutions.

Q: What is the significance of the shared base product number 110C1?

A: The 110C1 base product number indicates both parts belong to the same RF Solutions transmitter family and share compatible mechanical form factors and electrical interfaces. However, frequency variants within this family are not interchangeable without system redesign.

Q: Why is the 110C1-315AR2 listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. Remaining inventory may be available through authorized distributors, but long-term availability cannot be guaranteed. Active alternatives such as the 110C1-433A should be evaluated for new designs.

Q: Are there electrical differences between the 110C1-315AR2 and 110C1-433A beyond frequency?

A: The 110C1-433A supports both AM and FM modulation, whereas the 110C1-315AR2 is specified for AM only. Power output specifications are not provided for the 110C1-433A in the available data. Detailed electrical specifications should be obtained from RF Solutions datasheets for complete comparison.

Q: What packaging differences exist between these parts?

A: The 110C1-315AR2 packaging is listed as unspecified in available data. The 110C1-433A is supplied in bag packaging. Packaging format may affect handling, storage, and integration into assembly processes.

Q: Is the 110C1-433A suitable for applications requiring KeeLoq protocol support?

A: The 110C1-315AR2 is explicitly specified as KeeLoq-compatible. The 110C1-433A is listed as a general transmitter without KeeLoq designation in the provided data. Protocol compatibility must be verified against detailed product specifications before substitution.
