TL7705ACDRG4 Equivalent & Substitute Parts

Part Overview

The TL7705ACDRG4 is a Power Management Integrated Circuit (PMIC) functioning as a supervisor with open drain or open collector output for single-channel voltage monitoring and reset control. This component is classified as obsolete, which necessitates identification of active equivalent parts to maintain design continuity and ensure long-term supply chain reliability. The part operates across the industrial temperature range of 0°C to 70°C and is housed in an 8-SOIC surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL7705ACDRG4 is determined by strict equivalence across the following critical parameters:

• Voltage threshold specification (4.55V)
• Single-channel voltage monitoring capability
• Open drain or open collector output configuration
• Active high/active low reset functionality
• 1µs maximum propagation delay
• 8-SOIC surface mount package with identical physical dimensions
• Operating temperature range compatibility (0°C ~ 70°C)
• RoHS3 compliance and REACH unaffected status

The TL7705ACDR meets all these criteria and shares the same base product number (TL7705), confirming functional and electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TL7705ACDR is the direct active equivalent for the obsolete TL7705ACDRG4. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications, package geometry, and compliance certifications. The TL7705ACDR carries active product status with significantly higher inventory availability (51,160 units in stock versus 15,905 units for the obsolete variant), ensuring reliable supply chain access for new designs and production requirements. Both parts satisfy ROHS3 compliance and REACH unaffected requirements, making the TL7705ACDR suitable for direct substitution in applications requiring power supervision and reset control with 4.55V threshold monitoring.

Frequently Asked Questions (FAQ)

Q: Can the TL7705ACDR be used as a direct replacement for the TL7705ACDRG4?

A: Yes. Both parts share identical electrical specifications, including voltage threshold (4.55V), output configuration (open drain or open collector), reset characteristics (active high/active low), and propagation delay (1µs maximum). The 8-SOIC package dimensions are identical, enabling direct PCB-level substitution without design modification.

Q: What is the difference between the TL7705ACDRG4 and TL7705ACDR?

A: The primary difference is product status. The TL7705ACDRG4 is obsolete, while the TL7705ACDR is active. The suffix variation reflects manufacturing date codes and packaging configurations, but electrical and functional performance remain equivalent.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory and environmental compliance requirements are satisfied by either part.

Q: What packaging options are available for the TL7705ACDR?

A: The TL7705ACDR is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production volume requirements.

Q: Is the 8-SOIC package footprint identical between both parts?

A: Yes. Both the TL7705ACDRG4 and TL7705ACDR use the 8-SOIC package with 0.154" width and 3.90mm overall dimensions, ensuring mechanical compatibility without PCB redesign.
