Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLK2541PFPR is determined by compatibility across the following critical parameters:

• Voltage Supply Range: 2.3V ~ 2.7V (must match or encompass)
• Operating Temperature Range: -40°C ~ 85°C (must match or exceed)
• Mounting Type: Surface Mount (required for PCB compatibility)
• Interface Category: Transceiver (functional classification)
• RoHS and Compliance Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 3 (168 Hours) (handling and storage requirement)

The TLK2501IRCP qualifies as a manufacturer-recommended substitute based on alignment with these core parameters. While the TLK2501IRCP operates at higher data rates (2.5Gbps) and uses a different package format (64-HVQFP versus 80-HTQFP), it maintains electrical compatibility through identical supply voltage, operating temperature range, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TLK2501IRCP is designated as the manufacturer-recommended substitute for the obsolete TLK2541PFPR. Both components maintain identical supply voltage specifications (2.3V ~ 2.7V) and operating temperature ranges (-40°C ~ 85°C), ensuring electrical compatibility in existing system designs. Both components carry ROHS3 compliance and identical moisture sensitivity ratings, satisfying regulatory and handling requirements.

The primary design consideration is package format transition: the TLK2541PFPR uses 80-HTQFP (12x12) packaging, while the TLK2501IRCP uses 64-HVQFP (10x10) packaging. This difference requires PCB layout modification and footprint redesign. The TLK2501IRCP is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete TLK2541PFPR.

Frequently Asked Questions (FAQ)

Q: Can the TLK2501IRCP directly replace the TLK2541PFPR without PCB modification?

A: No. The TLK2501IRCP uses a 64-HVQFP (10x10) package format, while the TLK2541PFPR uses 80-HTQFP (12x12) packaging. PCB footprint redesign and layout modification are required for physical and electrical integration.

Q: Are the supply voltage requirements identical between these components?

A: Yes. Both the TLK2541PFPR and TLK2501IRCP operate within the 2.3V ~ 2.7V supply voltage range, eliminating the need for power supply circuit modifications.

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

A: The TLK2541PFPR is classified as obsolete, indicating discontinued manufacturing and limited availability. The TLK2501IRCP maintains active production status, ensuring reliable long-term supply and technical support from Texas Instruments.

Q: Do both components meet the same compliance and handling requirements?

A: Yes. Both components are ROHS3 compliant and carry identical Moisture Sensitivity Level ratings of 3 (168 Hours), satisfying regulatory requirements and storage/handling protocols.

Q: What functional differences exist between these transceiver components?

A: The TLK2501IRCP is specified as a Serializer/Deserializer with 2.5Gbps data rate capability, while the TLK2541PFPR is classified as a general transceiver. Functional compatibility depends on specific application requirements and signal protocol specifications.
