Key Parameters

Substitute Part Grouping Explanation

Substitution of the VIPER-S4 is determined by the following critical parameters that must align between the main part and substitute candidates:

Primary Substitution Criteria:

• Operating frequency: 433.92MHz (mandatory match)
• Channel configuration: 4-channel capability (mandatory match)
• Function type: Remote control system with transmitter and receiver functionality (mandatory match)
• Power output classification: 10mW / 10dBm range (equivalent)
• Supply voltage compatibility: Operating range must accommodate system requirements

The QUANTA-4S4 satisfies these substitution criteria as an active product offering identical frequency operation, 4-channel remote control functionality, and equivalent power output specifications. The QUANTA-4S4 represents the manufacturer-recommended equivalent for VIPER-S4 applications.

Parameter Comparison

Engineering Selection Recommendations

QUANTA-4S4 as Primary Substitute:

The QUANTA-4S4 is the manufacturer-recommended substitute for VIPER-S4 applications. Both components share identical frequency operation (433.92MHz), 4-channel remote control architecture, and equivalent power output specifications. The QUANTA-4S4 maintains active product status with current manufacturing support, whereas the VIPER-S4 is obsolete.

Critical Design Consideration:

The supply voltage range differs between the two components. The VIPER-S4 operates from 10V to 30V, while the QUANTA-4S4 operates from 2.9V to 3.3V. System designs must verify that power supply architecture can accommodate the QUANTA-4S4 voltage requirements or implement appropriate voltage regulation circuitry.

Compliance Status:

Both components maintain unlimited moisture sensitivity level (MSL 1) and comply with RoHS directives. The QUANTA-4S4 carries ROHS3 compliance certification, representing current regulatory alignment. Both components share identical ECCN classification (5A991G) for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can QUANTA-4S4 directly replace VIPER-S4 in existing designs?

A: Functional substitution is valid for 433.92MHz 4-channel remote control applications. However, the supply voltage range difference (10V~30V versus 2.9V~3.3V) requires circuit-level evaluation. Direct socket replacement is not possible without power supply modification.

Q: What is the significance of the LoRa protocol in QUANTA-4S4?

A: The QUANTA-4S4 incorporates LoRa modulation protocol, which was not specified for the VIPER-S4. This represents an enhanced feature set in the substitute component. System compatibility depends on whether existing receiver infrastructure supports LoRa protocol operation.

Q: Are both components RoHS compliant?

A: Yes. The VIPER-S4 is RoHS Compliant, and the QUANTA-4S4 is ROHS3 Compliant. Both meet current environmental and hazardous substance restrictions. ROHS3 represents the current regulatory standard.

Q: What packaging differences exist between these components?

A: The VIPER-S4 packaging is specified as "-" (not detailed in available documentation). The QUANTA-4S4 is supplied in Box packaging. Procurement specifications should confirm packaging requirements for your application.

Q: Are there inventory considerations for component selection?

A: The VIPER-S4 has 953 pieces in stock as new original inventory. The QUANTA-4S4 has 662 pieces in stock. Both represent available inventory; however, the VIPER-S4 is obsolete and represents end-of-life stock. New designs should specify QUANTA-4S4 for long-term supply chain stability.

Q: Do both components share the same export control classification?

A: Yes. Both VIPER-S4 and QUANTA-4S4 carry identical ECCN classification (5A991G), indicating equivalent export control treatment for international procurement.
