S-80138ALMC-JAXT2G Equivalent & Substitute Parts

Part Overview

The S-80138ALMC-JAXT2G is a single-channel voltage supervisor IC in SOT-23-5 surface mount packaging, designed for power management applications requiring voltage detection and reset signal generation. This device features push-pull totem pole output configuration with active low reset functionality and a 3.8V threshold voltage.

The S-80138ALMC-JAXT2G carries a "Not For New Designs" product status, indicating it has been superseded in the manufacturer's product line. For new design implementations or when current inventory becomes unavailable, parametric equivalent alternatives must be identified based on matching electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the S-80138ALMC-JAXT2G is determined by strict equivalence across the following critical parameters:

Electrical specifications: Single-channel voltage detection, 3.8V threshold voltage, push-pull totem pole output, active low reset with 32.5ms minimum timeout, and -40°C to 85°C operating temperature range.

Mechanical specifications: SOT-23-5 package (SC-74A, SOT-753), surface mount configuration, and tape & reel packaging format.

Compliance requirements: ROHS3 compliance, MSL Level 1, and REACH unaffected status.

The S-80138ALMC-JAXT2U meets all these criteria and qualifies as a parametric equivalent substitute. The primary distinction between these parts is product lifecycle status: the main part is designated "Not For New Designs" while the substitute maintains "Active" status, making it the preferred selection for ongoing production and new implementations.

Parameter Comparison

Engineering Selection Recommendations

The S-80138ALMC-JAXT2U is the direct parametric equivalent for the S-80138ALMC-JAXT2G. Both parts share identical electrical and mechanical specifications, with the substitute offering the advantage of active product status. The S-80138ALMC-JAXT2U maintains full ROHS3 compliance and REACH unaffected certification, ensuring regulatory alignment for current and future production requirements.

For applications currently using the S-80138ALMC-JAXT2G, transition to the S-80138ALMC-JAXT2U is supported without circuit modification or design revision. The substitute part is available in significantly higher inventory volume (10,049 units versus 787 units), providing improved supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the S-80138ALMC-JAXT2U be used as a direct replacement for the S-80138ALMC-JAXT2G without PCB modifications?

A: Yes. Both parts are electrically and mechanically identical. The SOT-23-5 package footprint, pin configuration, voltage threshold, output characteristics, and reset timing are equivalent. No circuit changes are required.

Q: What is the significance of the "Not For New Designs" status on the S-80138ALMC-JAXT2G?

A: This designation indicates the manufacturer has transitioned this part to end-of-life status and recommends using the active equivalent (S-80138ALMC-JAXT2U) for new product development. Existing designs may continue using available inventory, but new implementations should adopt the active part number.

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

A: No. Both parts maintain identical ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status. Regulatory requirements are fully satisfied by either part number.

Q: What is the difference between the S-80138ALMC-JAXT2G and S-80138ALMC-JAXT2U part numbers?

A: The parts are functionally identical. The suffix variation (G versus U) reflects manufacturer product lifecycle management. The U suffix indicates the active production version, while the G suffix identifies the superseded variant.

Q: Is the SOT-23-5 package suitable for high-volume surface mount assembly?

A: Yes. The SOT-23-5 package is a standard surface mount configuration widely supported by automated assembly equipment. Both part numbers are supplied in tape & reel format, optimized for high-speed pick-and-place operations.
