Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC7705IPWRG4 is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor with single-channel voltage monitoring
• Voltage Threshold: 4.55V monitoring threshold
• Output Configuration: Push-Pull, Totem Pole output stage
• Reset Behavior: Active High/Active Low capability
• Reset Timeout: 1.1ms minimum specification
• Operating Temperature: -40°C to 85°C industrial range
• Package: 8-TSSOP form factor with identical pinout
• Compliance: ROHS3 and REACH requirements

The TLC7705IPWR variant meets all these criteria and serves as a direct functional equivalent. The primary distinction is packaging format: the main part (TLC7705IPWRG4) uses tube packaging, while the substitute (TLC7705IPWR) is supplied in Tape & Reel format. Both share the identical base product number TLC7705 and maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TLC7705IPWR is the recommended substitute for the discontinued TLC7705IPWRG4. Both parts maintain identical electrical specifications, functional behavior, and mechanical compatibility. The substitute part carries active product status with significantly higher inventory availability (18,868 units versus 2,000 units), ensuring supply chain continuity.

Both variants satisfy ROHS3 compliance and REACH requirements, making them suitable for applications subject to environmental regulations. The packaging format difference (Tape & Reel versus tube) does not affect electrical performance or PCB assembly compatibility; this distinction is purely a procurement and handling consideration.

For new designs or production transitions, the TLC7705IPWR should be specified to leverage superior availability and active manufacturer support status.

Frequently Asked Questions (FAQ)

Q: Are TLC7705IPWRG4 and TLC7705IPWR electrically identical?

A: Yes. Both parts share the same base product number (TLC7705), voltage threshold (4.55V), output configuration (Push-Pull, Totem Pole), reset timeout (1.1ms minimum), and operating temperature range (-40°C to 85°C). All electrical parameters are equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. TLC7705IPWRG4 uses tube packaging, while TLC7705IPWR uses Tape & Reel (TR) format. Additionally, TLC7705IPWR maintains active product status with higher inventory availability.

Q: Can I use TLC7705IPWR as a direct replacement on my PCB?

A: Yes. Both parts use the identical 8-TSSOP package with the same pinout and mechanical dimensions (0.173", 4.40mm width). No PCB layout modifications are required.

Q: Does the packaging format affect circuit performance?

A: No. Packaging format is a supply chain and handling consideration only. Electrical performance and functional behavior are identical regardless of whether the part arrives in tube or Tape & Reel format.

Q: Why is TLC7705IPWRG4 discontinued?

A: The part is discontinued at DiGi Electronics. The functionally equivalent TLC7705IPWR remains in active production with Texas Instruments.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both TLC7705IPWRG4 and TLC7705IPWR are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.
