Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLK2201RCP is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Protocol: IEEE 802.3
• Transceiver Configuration: 1/1 (one driver, one receiver)
• Duplex Mode: Full
• Supply Voltage Range: 2.3V ~ 2.7V
• Package Type: 64-HVQFP (10x10)
• Mounting Type: Surface Mount

The TLK2201BIRCP qualifies as a direct substitute based on identical protocol, transceiver configuration, duplex mode, supply voltage range, and package specifications. Differences in product status, operating temperature range, and packaging format do not preclude functional equivalence within the defined electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The TLK2201BIRCP is the manufacturer-recommended substitute for the obsolete TLK2201RCP. Both components maintain identical electrical specifications for supply voltage, protocol compliance, and transceiver configuration. The TLK2201BIRCP offers an extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), providing broader environmental compatibility. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. The TLK2201BIRCP is currently available in Last Time Buy status, whereas the TLK2201RCP is obsolete. For new designs or ongoing procurement, the TLK2201BIRCP is the appropriate selection based on availability and manufacturer recommendation.

Frequently Asked Questions (FAQ)

Q: What makes TLK2201BIRCP a valid substitute for TLK2201RCP?

A: Both components share identical IEEE 802.3 protocol compliance, 1/1 transceiver configuration, full-duplex operation, 2.3V ~ 2.7V supply voltage range, and 64-HVQFP (10x10) package specifications. These parameters define functional equivalence for this component category.

Q: Are there differences in operating temperature ranges between these parts?

A: Yes. The TLK2201RCP operates from 0°C ~ 70°C, while the TLK2201BIRCP operates from -40°C ~ 85°C. The extended range of the TLK2201BIRCP does not prevent substitution; it provides additional environmental capability.

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

A: The TLK2201RCP is classified as obsolete, indicating end-of-life status. The TLK2201BIRCP is in Last Time Buy status, meaning limited availability remains before discontinuation. For procurement planning, the TLK2201BIRCP should be prioritized.

Q: Are the packaging formats identical?

A: Yes. Both components use 64-PowerVFQFP package type with 64-HVQFP (10x10) supplier device package specifications. Surface mount mounting type is identical for both parts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TLK2201RCP and TLK2201BIRCP are ROHS3 compliant with identical Moisture Sensitivity Level 3 (168 Hours) ratings.
