Engineering Selection Recommendations
The S-80829CLMC-B6OT2G from ABLIC Inc. is the qualified substitute for the obsolete TC53C2902ECTTR. Selection is based on the following engineering criteria:
- Functional Equivalence: Both devices operate as single-channel voltage supervisors with identical threshold voltage (2.9V), output configuration (push-pull, totem pole), and reset logic (active-low).
- Package Compatibility: Both devices utilize the SC-74A, SOT-753 package in SOT-23-5 supplier configuration, ensuring direct PCB footprint compatibility.
- Regulatory Alignment: Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification.
- Product Status: The substitute part maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.
- Environmental Specifications: Identical operating temperature range (-40°C to 85°C) and moisture sensitivity level (MSL 1) ensure equivalent reliability in target applications.
Frequently Asked Questions (FAQ)
Q: Can the S-80829CLMC-B6OT2G directly replace the TC53C2902ECTTR without PCB modifications?
A: Yes. Both devices share identical package geometry (SC-74A, SOT-753), pin configuration, and electrical specifications. Direct pin-for-pin substitution is possible without PCB layout changes.
Q: What is the primary reason for substitution?
A: The TC53C2902ECTTR is classified as obsolete. The S-80829CLMC-B6OT2G maintains active product status, ensuring continued availability and supply chain reliability.
Q: Are the voltage threshold specifications identical?
A: Yes. Both devices monitor a single voltage channel at a 2.9V threshold level with active-low reset output configuration.
Q: Do both parts meet the same regulatory requirements?
A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.
Q: What is the difference in reset timeout specification?
A: The TC53C2902ECTTR specifies a maximum reset timeout of 200µs. The S-80829CLMC-B6OT2G does not provide a specified reset timeout value in the available documentation. Verify application-specific timing requirements against the ABLIC device datasheet if reset timeout is a critical parameter.
Q: Are there packaging differences between the two parts?
A: No. Both devices are supplied in SOT-23-5 packages with SC-74A, SOT-753 case designations. Tape & Reel (TR) packaging is available for the ABLIC substitute, which may differ from the original Microchip packaging format.
Q: What is the moisture sensitivity level for both parts?
A: Both devices are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
