VIPER-S1 Equivalent & Substitute Parts Reference

Part Overview

The VIPER-S1 is a remote control system manufactured by RF Solutions operating at 433.92MHz with 1-channel handheld interface capability. This product is classified as obsolete, making identification of equivalent and substitute components essential for system maintenance, redesign, and procurement planning. The VIPER-S1 functions as an integrated RF transmitter and receiver set with 10mW output power and operates across a 10V to 30V supply voltage range. Due to its obsolete status, active alternative products must be evaluated for compatibility with existing applications.

Key Parameters

Substitute Part Grouping Explanation

The QUANTA-4S1 has been identified as a substitute for the VIPER-S1 based on the following alignment of critical parameters:

Matching Parameters:

• Frequency: 433.92MHz (identical RF operating frequency)
• Function: Remote Control System with transmitter and receiver capability
• Channels: 1 Channel (equivalent control capability)
• Power Output: 10dBm (equivalent to 10mW)
• Applications: General Purpose (same application category)
• RoHS Compliance: ROHS3 Compliant (meets regulatory requirements)
• Moisture Sensitivity Level: 1 (Unlimited) (identical environmental rating)
• ECCN Classification: 5A991G (identical export control classification)

Substitution Logic: The QUANTA-4S1 maintains the core RF functionality of the VIPER-S1 at the same frequency and channel configuration. Both products serve general-purpose remote control applications with equivalent power output specifications. The primary difference lies in voltage supply range and modulation protocol, which must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The QUANTA-4S1 is an active product substitute for the obsolete VIPER-S1 based on RF frequency alignment, equivalent power output, and identical channel configuration. Both products maintain the same ECCN classification (5A991G) and RoHS compliance status, ensuring regulatory continuity.

Critical Evaluation Points:

1. Voltage Supply Compatibility: The VIPER-S1 operates at 10V ~ 30V while the QUANTA-4S1 operates at 2.9V ~ 3.3V. Existing power supply designs must be reassessed for the substitute component.

2. Modulation Protocol: The QUANTA-4S1 implements LoRa modulation, whereas the VIPER-S1 modulation protocol is not specified in available documentation. System-level compatibility testing is required if protocol differences affect interoperability.

3. Product Status: The QUANTA-4S1 is actively manufactured by RF Solutions, ensuring long-term availability and supply chain stability compared to the obsolete VIPER-S1.

4. Compliance Certification: Both products meet RoHS requirements and share identical moisture sensitivity ratings, supporting direct substitution from an environmental and regulatory perspective.

Selection Basis:

Choose the QUANTA-4S1 as a substitute when RF frequency matching (433.92MHz), single-channel operation, and equivalent power output (10mW/10dBm) are primary requirements. Verify voltage supply compatibility with existing system power architecture before implementation.

Frequently Asked Questions (FAQ)

Q: Can the QUANTA-4S1 directly replace the VIPER-S1 in existing installations?

A: Direct replacement requires verification of voltage supply compatibility. The VIPER-S1 operates at 10V ~ 30V while the QUANTA-4S1 operates at 2.9V ~ 3.3V. Power supply redesign may be necessary. RF frequency and channel configuration are compatible.

Q: What is the primary reason for substituting the VIPER-S1?

A: The VIPER-S1 is classified as obsolete. The QUANTA-4S1 is an active product from the same manufacturer, ensuring continued availability, support, and compliance with current regulatory standards.

Q: Are the RF frequencies identical between these products?

A: Yes. Both the VIPER-S1 and QUANTA-4S1 operate at 433.92MHz, ensuring RF compatibility and interoperability in the same frequency band.

Q: What is the difference in modulation between these products?

A: The VIPER-S1 modulation protocol is not specified in available documentation. The QUANTA-4S1 uses LoRa modulation. System compatibility must be verified if protocol differences affect application requirements.

Q: Do both products meet RoHS compliance requirements?

A: Yes. The VIPER-S1 is RoHS Compliant and the QUANTA-4S1 is ROHS3 Compliant. Both products meet current RoHS regulatory requirements.
