Key Parameters

Substitute Part Grouping Explanation

Substitution of the CL4490-200-05 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Frequency band: 902MHz ~ 928MHz (ISM band)
• Modulation protocols: FHSS and FSK support
• Function: RF transceiver capability
• Sensitivity: -99dBm (receiver performance threshold)

Interface and Application Parameters:

• Original interface: USB
• Substitute interfaces: RS-232, RS-485 (alternative serial protocols within same product family)

Performance Trade-offs:

• Power output: 200mW (original) vs. 1000mW (substitute) — higher output available
• Data rate: 115.2kbps (original) vs. 76.8kbps (substitute) — reduced in substitute
• Supply voltage: 5V (original) vs. 7V ~ 18V (substitute) — wider range in substitute

The CL4490-1000-UPR-SP operates within the same Connexlink™ series and maintains core RF parameters (frequency, modulation, sensitivity) while offering active product status and improved environmental compliance.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Product Replacement:

The CL4490-200-05 is classified as obsolete and no longer in active production. The CL4490-1000-UPR-SP is the active equivalent within the Connexlink™ product family, maintaining identical RF performance specifications (frequency band, modulation protocols, and receiver sensitivity).

Compliance and Regulatory Status:

The CL4490-1000-UPR-SP holds RoHS Compliant certification and EAR99 export classification, providing superior regulatory standing compared to the obsolete status of the original part. The substitute demonstrates improved environmental compliance with MSL 1 (Unlimited) versus MSL 2 (1 Year).

Interface Consideration:

The primary difference is interface protocol: USB (original) versus RS-232/RS-485 (substitute). System integration requires interface adapter or redesign of host communication architecture. This is a design-level decision, not a direct pin-compatible substitution.

Power and Data Rate Trade-off:

The substitute provides 5× higher RF output power (1000mW vs. 200mW) but operates at reduced maximum data rate (76.8kbps vs. 115.2kbps). Applications requiring higher transmit power benefit from the substitute; applications requiring maximum data throughput may require alternative evaluation.

Frequently Asked Questions (FAQ)

Q: Can the CL4490-1000-UPR-SP directly replace the CL4490-200-05 without modification?

A: Direct pin-compatible replacement is not possible due to interface differences (USB vs. RS-232/RS-485). System-level integration changes are required, including host communication protocol adaptation and power supply voltage adjustment (5V to 7V–18V range).

Q: Are the RF performance characteristics identical between these parts?

A: Yes. Both parts operate in the 902MHz–928MHz frequency band, support FHSS and FSK modulation, and deliver -99dBm receiver sensitivity. RF link performance is equivalent.

Q: What is the significance of the MSL rating difference?

A: The CL4490-200-05 has MSL 2 (1 Year shelf life under controlled humidity), while the CL4490-1000-UPR-SP has MSL 1 (Unlimited shelf life). The substitute offers superior moisture tolerance and longer storage capability.

Q: Why does the substitute have lower maximum data rate?

A: The CL4490-1000-UPR-SP operates at 76.8kbps maximum, compared to 115.2kbps for the original. This is a design characteristic of the RS-232/RS-485 interface variant. Applications requiring 115.2kbps throughput must evaluate alternative solutions.

Q: Is the substitute suitable for new product designs?

A: Yes. The CL4490-1000-UPR-SP is active product status with RoHS compliance and EAR99 classification, making it appropriate for new designs. The original CL4490-200-05 is obsolete and unsuitable for new development.

Q: What power supply voltage is required for the substitute?

A: The CL4490-1000-UPR-SP requires 7V to 18V supply, compared to 5V for the original. System power architecture must be adjusted accordingly.
