TLC7733IPE4 Equivalent & Substitute Parts

Part Overview

The TLC7733IPE4 is a voltage supervisor integrated circuit manufactured by Texas Instruments, designed for power management applications requiring simple reset and power-on reset functionality. This device monitors a single voltage threshold at 2.93V and provides push-pull, totem pole output configuration in an 8-PDIP through-hole package.

The TLC7733IPE4 is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC7733IPE4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Single voltage monitoring channel
• Voltage threshold of 2.93V
• Push-pull, totem pole output configuration
• Active high/active low reset capability
• 1.1ms minimum reset timeout
• Operating temperature range of -40°C to 85°C
• 8-PDIP through-hole package format
• ROHS3 compliance and REACH unaffected status

The substitute part TLC7733IP meets all mandatory parameters and shares the same base product number (TLC7733) with identical electrical and mechanical specifications. The primary distinction is packaging format (tube versus individual) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The TLC7733IP serves as a direct parametric equivalent to the TLC7733IPE4. Both components are manufactured by Texas Instruments and maintain identical electrical specifications, threshold voltages, output configurations, and thermal operating ranges. Both parts satisfy ROHS3 compliance and REACH unaffected requirements.

The primary distinction between these parts is product lifecycle status. The TLC7733IPE4 is classified as obsolete, while the TLC7733IP is designated as Last Time Buy. This status difference reflects supply availability rather than functional or electrical divergence.

Selection between these parts should be based on:

1. Supply Availability: The TLC7733IP currently maintains higher inventory levels (1450 units) compared to the TLC7733IPE4 (833 units), supporting sustained procurement requirements.

2. Packaging Format: The TLC7733IPE4 is supplied in standard packaging, while the TLC7733IP is supplied in tube packaging. Verify that tube packaging is compatible with assembly and handling processes.

3. Product Lifecycle: Both parts are in end-of-life phases. Long-term design strategies should evaluate next-generation voltage supervisor alternatives from the TLC77xx series or equivalent product lines.

4. Regulatory Compliance: Both parts maintain identical compliance certifications, supporting use in regulated applications without additional qualification.

Frequently Asked Questions (FAQ)

Q: Can the TLC7733IP directly replace the TLC7733IPE4 in existing designs?

A: Yes. The TLC7733IP is a parametric equivalent with identical electrical specifications, voltage threshold, output configuration, reset timing, and operating temperature range. No circuit modifications are required for direct substitution.

Q: What is the difference between TLC7733IPE4 and TLC7733IP?

A: The primary differences are packaging format (standard versus tube) and product status (obsolete versus last time buy). All electrical and mechanical parameters are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the TLC7733IPE4 and TLC7733IP are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.

Q: What is the significance of "Last Time Buy" status for the TLC7733IP?

A: Last Time Buy status indicates that the manufacturer will accept orders for a limited period before discontinuing production. This part should be considered for procurement if long-term supply is required, though both parts are in end-of-life phases.

Q: Is the 8-PDIP package compatible with automated assembly equipment?

A: The 8-PDIP through-hole package is compatible with standard through-hole assembly processes. Verify that your assembly equipment supports 0.300" (7.62mm) DIP spacing and through-hole insertion.

Q: What are the voltage monitoring specifications for these parts?

A: Both parts monitor a single voltage channel with a threshold of 2.93V. The reset timeout is 1.1ms minimum, and the output provides active high/active low reset capability through push-pull, totem pole configuration.

Q: Should I consider alternative voltage supervisor products?

A: Given that both parts are in end-of-life status, designs requiring new production quantities should evaluate current-generation voltage supervisor alternatives. Consult Texas Instruments product documentation for recommended successors in the TLC77xx or equivalent product families.
