TPS2062CD Equivalent & Substitute Parts

Part Overview

The TPS2062CD is an active power switch/driver IC manufactured by Texas Instruments, designed for general-purpose load switching applications. This N-channel power switch features a 1:2 input-to-output ratio with high-side output configuration, capable of delivering 1A maximum output current per channel. The device is classified as Active product status and is widely used in power management circuits requiring controlled load switching with integrated fault protection.

Equivalent and substitute parts are identified when designs require alternative sourcing, inventory optimization, or when the primary part becomes unavailable while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS2062CD are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Number of Outputs: 2 channels
• Ratio - Input:Output: 1:2 configuration
• Output Configuration: High Side topology
• Output Type: N-Channel switching
• Voltage - Load: 4.5V ~ 5.5V operating range
• Current - Output (Max): 1A per channel
• Rds On (Typ): 90mOhm on-resistance
• Input Type: Non-Inverting logic
• Features: Load Discharge and Status Flag functionality
• Fault Protection: Current Limiting (Fixed), Over Temperature, Reverse Current, UVLO
• Operating Temperature: -40°C ~ 125°C (TJ)
• Package / Case: 8-SOIC form factor
• RoHS Status: ROHS3 Compliant

Only parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS2062CD and TPS2066CD are Active product status components manufactured by Texas Instruments. Both parts maintain identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts is based on inventory availability and supply chain considerations rather than technical differentiation.

Both parts are ROHS3 Compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, indicating equivalent reliability and handling requirements. The 8-SOIC surface mount package is consistent across both parts, ensuring PCB layout compatibility without design modifications.

Frequently Asked Questions (FAQ)

Q: Can TPS2066CD be used as a direct replacement for TPS2062CD?

A: Yes. The TPS2066CD is a parametric equivalent with identical electrical specifications, output configuration, current rating, on-resistance, fault protection features, operating temperature range, and 8-SOIC package. No circuit modifications are required.

Q: Are there any differences in package dimensions between TPS2062CD and TPS2066CD?

A: No. Both parts use the 8-SOIC package with 0.154" (3.90mm) width. PCB footprints are identical, and no layout changes are necessary.

Q: Do both parts have the same fault protection capabilities?

A: Yes. Both TPS2062CD and TPS2066CD include identical fault protection: Current Limiting (Fixed), Over Temperature protection, Reverse Current protection, and UVLO (Under Voltage Lock Out).

Q: What is the significance of the 1:2 input-to-output ratio?

A: The 1:2 ratio indicates that one input control signal manages two independent output channels. Each output can switch 1A maximum current independently while sharing the same input control logic.

Q: Are both parts suitable for the same load voltage range?

A: Yes. Both parts operate with load voltages in the 4.5V ~ 5.5V range, making them suitable for identical power supply applications.

Q: What does the 90mOhm Rds On specification mean for circuit design?

A: The 90mOhm on-resistance represents the channel resistance when the switch is conducting. This specification determines power dissipation and voltage drop across the switch during operation and is identical for both parts.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both parts are ROHS3 Compliant, carry identical MSL Level 1 ratings, and share the same REACH and ECCN classifications.
