Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC7703IDG4 is determined by strict equivalence across the following critical parameters:

• Supervisor Type: Single-channel reset/power-on reset functionality
• Voltage Threshold: 2.63V monitoring level
• Output Stage: Push-pull totem pole configuration with active high/active low reset capability
• Reset Timing: 1.1ms minimum reset timeout
• Package: 8-SOIC surface mount form factor
• Temperature Range: -40°C to 85°C operating specification
• Compliance: ROHS3 compliance and MSL Level 1 rating

The TLC7703ID is identified as a manufacturer-recommended substitute. Both parts share identical electrical specifications, threshold voltages, output configurations, and timing characteristics. The primary distinction is product status: TLC7703IDG4 is obsolete, while TLC7703ID maintains active production status.

Parameter Comparison

Engineering Selection Recommendations

The TLC7703ID is a direct functional equivalent to the TLC7703IDG4 across all specified electrical and mechanical parameters. Selection of TLC7703ID is supported by the following factors:

• Product Status: TLC7703ID maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete TLC7703IDG4.
• Compliance Alignment: Both parts maintain identical ROHS3 compliance and MSL Level 1 ratings, meeting regulatory and environmental requirements.
• Electrical Equivalence: Identical voltage threshold (2.63V), output configuration (push-pull totem pole), reset timing (1.1ms minimum), and operating temperature range (-40°C to 85°C) ensure functional interchangeability.
• Package Compatibility: Both parts use the 8-SOIC surface mount package, permitting direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can TLC7703ID be used as a direct replacement for TLC7703IDG4 in existing designs?

A: Yes. The TLC7703ID is electrically and mechanically equivalent to the TLC7703IDG4. All critical parameters—voltage threshold, output configuration, reset timing, package type, and operating temperature range—are identical. No circuit modifications or PCB redesign are required.

Q: What is the primary reason to transition from TLC7703IDG4 to TLC7703ID?

A: The TLC7703IDG4 is classified as obsolete, while TLC7703ID maintains active production status. This transition ensures sustained component availability and supply chain reliability for ongoing production.

Q: Are there packaging differences between TLC7703IDG4 and TLC7703ID?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. The primary packaging difference is that TLC7703IDG4 is supplied in standard packaging, while TLC7703ID is supplied in tube packaging. This does not affect electrical performance or PCB compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TLC7703IDG4 and TLC7703ID are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. Compliance certifications are identical.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in supervisor type, voltage threshold (2.63V), output configuration (push-pull totem pole), reset timing (1.1ms minimum), package type (8-SOIC), operating temperature range (-40°C to 85°C), and compliance certifications (ROHS3, MSL Level 1).
