Key Parameters

Substitute Part Grouping Explanation

The SS450-002 is identified as a direct substitute for the SS420-002 based on the following critical parameters that determine functional compatibility:

• Frequency Band: Both operate at 2.4GHz, ensuring compatibility with the same RF spectrum
• Power Output: Both deliver 20dBm output power, maintaining equivalent transmission capability
• Sensitivity: Both achieve -105dBm sensitivity, ensuring equivalent reception performance
• Supply Voltage: Both accept 12V ~ 24VDC input, allowing use in identical power supply configurations
• Series Compatibility: Both belong to the simplySNAP product family, ensuring architectural alignment
• Tariff Classification: Both share HTSUS code 8517.62.0090, confirming equivalent product classification
• Moisture Sensitivity: Both rated MSL 1 (Unlimited), indicating identical environmental handling requirements

The primary difference lies in the wireless protocol: SS420-002 uses 802.11 a/b/g, while SS450-002 uses 802.15.4. This substitution is valid where the application requirements permit protocol transition within the 2.4GHz band.

Parameter Comparison

Engineering Selection Recommendations

The SS450-002 is an active product, whereas the SS420-002 is obsolete. Selection between these parts must be based on protocol requirements and application constraints:

SS420-002 Selection: Use only when 802.11 a/b/g protocol compatibility is mandatory and existing inventory is available. This part is no longer manufactured.

SS450-002 Selection: Use for new designs and ongoing production. This part is actively manufactured and supported. The 802.15.4 protocol operates within the same 2.4GHz frequency band with identical RF performance characteristics (sensitivity and power output). Electrical and environmental specifications are equivalent, permitting direct substitution in power supply and handling procedures.

Both parts share identical ECCN and HTSUS classifications, ensuring equivalent export control and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can SS450-002 directly replace SS420-002 in existing systems?

A: Electrical and RF performance parameters are identical (frequency, power output, sensitivity, supply voltage). However, the wireless protocol differs: SS420-002 uses 802.11 a/b/g while SS450-002 uses 802.15.4. Substitution is valid only if the system architecture and network infrastructure support 802.15.4 protocol operation.

Q: Are there interface differences between these parts?

A: SS420-002 specifies Ethernet and USB interfaces. SS450-002 does not list interface specifications in the provided data. Interface compatibility must be verified against specific application requirements before substitution.

Q: Do both parts require identical power supply specifications?

A: Yes. Both parts accept 12V ~ 24V supply voltage, permitting use with identical power supply configurations and wiring.

Q: What is the significance of the product status difference?

A: SS420-002 is obsolete and no longer manufactured. SS450-002 is active and currently produced. For new designs and long-term availability, SS450-002 is the appropriate selection.

Q: Are packaging and moisture handling requirements the same?

A: Both parts are rated MSL 1 (Unlimited), indicating identical moisture sensitivity and environmental handling requirements. SS450-002 is specified as Bulk packaging; SS420-002 packaging is not specified in the provided data.
