Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI2EQX6741SLZDEX is determined by the following critical parameters:

• Signal Type Compatibility: Both input and output must support CML signaling
• Signal Conditioning: Input equalization and output pre-emphasis capability required
• Data Rate Capability: Minimum 6Gbps support for SATA3 applications
• Package Type: Surface mount with exposed pad configuration
• Supply Voltage: Operating voltage range must accommodate the application requirements
• Compliance: RoHS3 compliance and REACH unaffected status maintained

The SN65LVCP1412RLHR from Texas Instruments meets these substitution criteria. While it provides enhanced specifications (2-channel configuration, 14.2Gbps data rate capability, and wider supply voltage range), it maintains full backward compatibility with the core functional requirements of CML input/output buffering with signal conditioning for high-speed serial applications.

Parameter Comparison

Engineering Selection Recommendations

The SN65LVCP1412RLHR is the designated substitute for the obsolete PI2EQX6741SLZDEX based on functional equivalence in signal conditioning architecture and CML interface support. Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Key considerations for selection:

• Supply Voltage: The SN65LVCP1412RLHR operates at 2.375V ~ 3.465V, differing from the PI2EQX6741SLZDEX at 1.05V. Circuit design must accommodate this voltage requirement.
• Package Footprint: The substitute uses a 24-pin package versus the original 20-pin configuration, requiring PCB layout modification.
• Channel Count: The SN65LVCP1412RLHR provides 2 channels compared to 1 channel in the original part. Single-channel applications may utilize only one channel or require design adaptation.
• Product Status: The SN65LVCP1412RLHR is classified as Last Time Buy, indicating limited future availability. Long-term production designs should evaluate additional alternatives or plan inventory accordingly.

Frequently Asked Questions (FAQ)

Q: Can the SN65LVCP1412RLHR directly replace the PI2EQX6741SLZDEX without design changes?

A: Direct pin-for-pin replacement is not possible due to different package pin counts (24 vs. 20) and supply voltage requirements (2.375V ~ 3.465V vs. 1.05V). PCB layout and power supply modifications are required.

Q: What is the primary reason for substitution?

A: The PI2EQX6741SLZDEX is classified as Obsolete. The SN65LVCP1412RLHR provides equivalent signal conditioning functionality (input equalization and output pre-emphasis) with CML interface support, making it suitable for applications requiring SATA3 buffering.

Q: Are both parts RoHS compliant?

A: Yes, both the PI2EQX6741SLZDEX and SN65LVCP1412RLHR are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance for EU and international markets.

Q: What is the difference in data rate capability?

A: The PI2EQX6741SLZDEX supports 6Gbps maximum data rate for SATA3 applications. The SN65LVCP1412RLHR supports 14.2Gbps, providing headroom for higher-speed serial protocols while remaining backward compatible with 6Gbps operation.

Q: How does the MSL rating affect component handling?

A: The PI2EQX6741SLZDEX has MSL 1 (Unlimited shelf life), while the SN65LVCP1412RLHR has MSL 2 (1 Year shelf life). The substitute requires stricter moisture control during storage and handling to prevent solder joint degradation.

Q: Can I use only one channel of the SN65LVCP1412RLHR in a single-channel application?

A: Yes, the SN65LVCP1412RLHR can be configured for single-channel operation. Unused channels must be properly terminated according to Texas Instruments design guidelines to ensure signal integrity.
