Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 110C2-315AR2 is determined by the following critical parameters:

Primary Substitution Criteria:

• Base Product Number: 110C2 (common platform)
• Manufacturer: RF Solutions (same manufacturer ecosystem)
• Voltage Supply: 12V (identical power requirement)
• Function: Transmitter capability

Frequency Consideration: The 110C2-315AR2 operates at 315MHz. Substitute parts may operate at alternative ISM band frequencies (such as 433MHz) provided the application design accommodates frequency variation and regulatory compliance for the target deployment region.

Modulation Compatibility: The main part uses AM modulation. Substitute parts supporting AM modulation or dual AM/FM capability maintain functional compatibility with AM-based receiver systems.

Interface and Form Factor: Handheld 2-switch interface configuration is the specified form factor for this product line. Substitutes must maintain equivalent mechanical and electrical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 110C2-315AR2 is obsolete. The 110C2-433A is active and currently in production, providing assured long-term availability and supply chain stability.

Compliance and Certification: The 110C2-433A carries ROHS3 compliance certification, meeting current environmental and material restriction standards. The main part lists RoHS status as not applicable, reflecting its obsolete classification. For new designs or systems requiring current compliance documentation, the 110C2-433A provides documented regulatory alignment.

Frequency Band Difference: The primary technical distinction is frequency operation: 315MHz versus 433MHz. Both frequencies operate within ISM bands; however, system-level receiver compatibility must be verified. The 110C2-433A operates in the 433MHz ISM band, which is widely supported in European and global markets.

Modulation Support: The 110C2-433A supports both AM and FM modulation, providing operational flexibility beyond the AM-only specification of the main part. Systems designed for AM operation will function with this substitute.

Supply Voltage Alignment: Both parts require 12V supply voltage, eliminating power supply redesign requirements.

Selection Path: For applications requiring direct 315MHz operation, the 110C2-315AR2 remains the specified component. For new implementations or systems where 433MHz operation is acceptable, the 110C2-433A provides an active, compliant alternative with documented availability.

Frequently Asked Questions (FAQ)

Q: Can the 110C2-433A directly replace the 110C2-315AR2 in existing systems?

A: Direct replacement depends on receiver compatibility. The 110C2-433A operates at 433MHz while the main part operates at 315MHz. If the receiving system is tuned to 315MHz, frequency mismatch will prevent communication. Receiver compatibility must be confirmed before substitution.

Q: What is the significance of the Base Product Number 110C2 being identical?

A: The shared Base Product Number 110C2 indicates both parts belong to the same RF Solutions product family and platform. This common heritage ensures electrical interface compatibility and similar mechanical form factors, supporting substitution feasibility within the same system architecture.

Q: Does the 110C2-433A support KeeLoq protocol like the main part?

A: The provided specifications indicate the 110C2-315AR2 includes KeeLoq function. The 110C2-433A specification lists "Transmitter" function without explicit KeeLoq notation. Protocol compatibility should be confirmed through detailed technical documentation before substitution in KeeLoq-dependent systems.

Q: Why is RoHS compliance different between the two parts?

A: The 110C2-315AR2 is obsolete and predates current RoHS3 requirements; its RoHS status is listed as not applicable. The 110C2-433A is an active product meeting current ROHS3 compliance standards. For procurement requiring current environmental certifications, the 110C2-433A satisfies modern regulatory requirements.

Q: Are there packaging differences between these parts?

A: The main part packaging is unspecified in available data. The 110C2-433A is supplied in bag packaging. Packaging format may affect handling, storage, and integration into assembly processes; confirm packaging requirements for your application workflow.

Q: What does "Vendor Undefined" REACH status mean for the 110C2-433A?

A: REACH status listed as "Vendor Undefined" indicates the manufacturer has not provided explicit REACH compliance documentation in the available data. For applications requiring documented REACH compliance, contact the manufacturer directly for current certification status.

Q: Can both parts operate at 12V supply voltage?

A: Yes. Both the 110C2-315AR2 and 110C2-433A require 12V supply voltage. No power supply modifications are necessary when considering substitution between these parts.

Q: What is the operational range difference between these transmitters?

A: The 110C2-315AR2 specifies 50-meter range. The 110C2-433A range specification is not provided in the available data. Range performance may vary based on frequency, antenna design, and environmental factors; confirm range requirements for your application.
