Substitute Part Grouping Explanation

Substitution of the S-80154ALMC-JBFT2G with the S-80154ALMC-JBFT2U is based on identical alignment across all critical electrical and mechanical parameters. The following parameters determine substitutability:

• Voltage threshold: 5.4V (identical)
• Output configuration: Push-Pull, Totem Pole (identical)
• Reset functionality: Active Low with 32.5ms minimum timeout (identical)
• Operating temperature range: -40°C ~ 85°C (identical)
• Package specification: SOT-23-5 / SC-74A, SOT-753 (identical)
• Mounting type: Surface Mount (identical)
• Compliance certifications: ROHS3, REACH Unaffected, MSL 1 (identical)

The S-80154ALMC-JBFT2U maintains the same base product number (S-801 series) and functional classification as a single-channel voltage detector supervisor with identical electrical performance characteristics.

Engineering Selection Recommendations

The S-80154ALMC-JBFT2U is the appropriate selection for applications currently using or requiring the S-80154ALMC-JBFT2G. The substitute part maintains full electrical and mechanical compatibility with identical voltage threshold, output topology, reset characteristics, and thermal operating range. The primary distinction is product lifecycle status: the S-80154ALMC-JBFT2U carries active product status, ensuring continued availability and manufacturing support, whereas the S-80154ALMC-JBFT2G is designated not for new designs.

Both parts satisfy ROHS3 compliance and REACH unaffected requirements. The MSL 1 rating indicates unlimited shelf life under standard storage conditions for both variants. Selection of the S-80154ALMC-JBFT2U provides equivalent functionality with enhanced supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Are the S-80154ALMC-JBFT2G and S-80154ALMC-JBFT2U electrically interchangeable?

A: Yes. Both parts are identical in voltage threshold (5.4V), output configuration (push-pull, totem pole), reset timing (32.5ms minimum active-low reset), and operating temperature range (-40°C ~ 85°C). No circuit modifications are required for substitution.

Q: Can the S-80154ALMC-JBFT2U be used as a direct replacement on existing PCBs designed for the S-80154ALMC-JBFT2G?

A: Yes. Both parts use the identical SOT-23-5 package (SC-74A, SOT-753) with surface mount configuration. Pin-to-pin compatibility is complete, allowing direct PCB substitution without layout changes.

Q: What is the significance of the "Not For New Designs" status on the S-80154ALMC-JBFT2G?

A: This designation indicates the part has reached end-of-life or is transitioning out of active production. The S-80154ALMC-JBFT2U, with active product status, is the recommended alternative for new applications and ongoing production requirements.

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

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating. Regulatory and environmental certifications are equivalent.

Q: What is the difference between the part numbers S-80154ALMC-JBFT2G and S-80154ALMC-JBFT2U?

A: The final character designates the product lifecycle variant. The "G" suffix indicates not for new designs status, while the "U" suffix indicates active product status. All other specifications remain identical.
