Key Parameters

Substitute Part Grouping Explanation

Substitution of the 109990022 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 433MHz ISM band operation
• RF Family/Standard: General ISM < 1GHz
• Modulation Support: FSK, GFSK, OOK capability
• Serial Interface: SPI communication protocol
• Voltage Supply Range: 1.8V ~ 3.6V compatibility
• Mounting Type: Surface Mount configuration
• Package Classification: Module form factor

Performance Parameters (Allowable Variance):

• Data Rate: Substitute must support minimum 256Kbps
• Power Output: Substitute must support minimum 20dBm
• Sensitivity: Substitute must achieve minimum -121dBm
• Current Consumption: Substitute specifications must be evaluated against system power budget constraints
• Operating Temperature: Substitute range must encompass or exceed -20°C ~ 85°C

The ZETA-433-SO qualifies as a substitute based on matching all mandatory parameters while maintaining functional equivalence within the ISM < 1GHz transceiver module category.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 109990022 is classified as Obsolete. The ZETA-433-SO is classified as Active, ensuring continued availability and manufacturer support for new designs and production requirements.

Compliance and Certification: Both parts share identical ECCN (EAR99) and HTSUS (8473.30.1180) classifications. The ZETA-433-SO carries ROHS3 Compliant and REACH Unaffected certifications, providing additional regulatory compliance documentation for applications requiring environmental and hazardous substance compliance verification.

Performance Trade-offs: The ZETA-433-SO demonstrates reduced power output (13dBm vs. 20dBm) and lower sensitivity (-116dBm vs. -121dBm). These parameters must be evaluated against specific link budget requirements. The substitute offers superior current efficiency in both receive (10mA vs. 18.5mA) and transmit (18mA ~ 30mA vs. 85mA) modes, providing advantages for battery-powered applications. Extended operating temperature range (-40°C ~ 85°C vs. -20°C ~ 85°C) accommodates wider environmental deployment scenarios.

Selection Criteria: Selection between the main part and substitute should be based on: (1) availability requirements due to obsolescence status; (2) power consumption constraints in the target application; (3) link budget calculations accounting for reduced output power and sensitivity; (4) environmental temperature operating range requirements; (5) regulatory compliance documentation needs.

Frequently Asked Questions (FAQ)

Q: Can the ZETA-433-SO directly replace the 109990022 in existing designs?

A: Direct replacement requires evaluation of link budget impact. The ZETA-433-SO operates at lower output power (13dBm vs. 20dBm) and reduced sensitivity (-116dBm vs. -121dBm). If the original design included margin above minimum link budget requirements, substitution is feasible. If the design operated at link budget limits, performance degradation may occur. SPI interface compatibility and voltage supply range (1.8V ~ 3.6V) are identical, supporting pin-level compatibility in most configurations.

Q: What are the key differences in current consumption?

A: The ZETA-433-SO consumes significantly less current in both operational modes. Receive current is 10mA (vs. 18.5mA), and transmit current ranges 18mA ~ 30mA (vs. 85mA). This 65% reduction in transmit current provides substantial power savings in battery-powered applications, though this advantage must be weighed against reduced transmit power output.

Q: Are there antenna considerations for substitution?

A: The ZETA-433-SO is specified as "Antenna Not Included," whereas the 109990022 antenna type is not specified in available documentation. System design must account for external antenna requirements and impedance matching for the ZETA-433-SO implementation.

Q: What is the significance of the extended temperature range in the ZETA-433-SO?

A: The ZETA-433-SO operates from -40°C ~ 85°C, compared to -20°C ~ 85°C for the 109990022. This extended lower temperature limit accommodates outdoor and industrial applications requiring operation in cold environments. Applications limited to -20°C ~ 85°C do not require this extended range.

Q: How do the modulation capabilities compare?

A: Both modules support identical modulation schemes: FSK, GFSK, and OOK. No functional limitation exists in modulation support for substitution purposes.

Q: What compliance certifications should be verified for the substitute?

A: The ZETA-433-SO carries ROHS3 Compliant and REACH Unaffected certifications. Applications requiring environmental compliance documentation should reference these certifications. Both parts share EAR99 export classification.
