Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN75DP119RHHT are identified based on exact parametric equivalence across all critical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Data Rate (Max): 2.7Gbps
• Number of Channels: 2
• Signal Conditioning: Input Equalization, Output Pre-Emphasis
• Voltage - Supply: 3V ~ 3.6V
• Current - Supply: 24.9mA
• Delay Time: 325ps
• Operating Temperature: 0°C ~ 85°C
• Package / Case: 36-VFQFN Exposed Pad
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

Parts matching all these parameters are classified as parametric equivalents and direct substitutes. Packaging format (Tape & Reel) is consistent across all equivalent parts.

Parameter Comparison

Engineering Selection Recommendations

Both the SN75DP119RHHT and SN75DP119RHHR are active production parts from Texas Instruments with identical electrical and mechanical specifications. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. The SN75DP119RHHR offers higher inventory availability at 3730 units compared to 959 units for the SN75DP119RHHT. Selection between these parts should be based on procurement lead time requirements and inventory availability, as all functional and compliance parameters are equivalent.

Frequently Asked Questions (FAQ)
