Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TCC-103A-RT is determined by the following critical parameters:

• Manufacturer: onsemi (same manufacturer ensures design compatibility and supply chain continuity)
• Product Status: Both main and substitute parts are classified as obsolete, indicating similar lifecycle stage and availability constraints
• Mounting Type: Surface Mount (consistent with PCB assembly requirements)
• Compliance & Certifications: REACH Unaffected and EAR99 classification (regulatory alignment)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (identical handling and storage requirements)
• HTSUS Code: 8542.39.0001 (same tariff classification)

The TCC-303A-RT is identified as a substitute part based on manufacturer alignment, obsolete product status, identical compliance certifications, and equivalent moisture sensitivity classification. Both components share the same regulatory framework and supply chain characteristics.

Parameter Comparison

Engineering Selection Recommendations

Selection between TCC-103A-RT and TCC-303A-RT must be based on the following engineering criteria:

Regulatory & Compliance Alignment: Both components share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8542.39.0001), ensuring equivalent regulatory compliance for procurement and deployment.

Supply Chain & Lifecycle Status: Both parts are classified as obsolete products from the same manufacturer (onsemi). Component selection should prioritize current inventory availability and lead time requirements, as both face similar long-term availability constraints.

Moisture Handling: Identical MSL 1 (Unlimited) classification ensures equivalent moisture sensitivity and storage requirements, with no additional handling procedures required when transitioning between these components.

Package Considerations: The TCC-103A-RT uses a 16-CSP (2.1x1.9mm) package, while the TCC-303A-RT uses a 12-WLCSP (1.38x1.03mm) package. PCB layout and footprint compatibility must be evaluated before component substitution.

Frequently Asked Questions (FAQ)

Q: What makes TCC-303A-RT a valid substitute for TCC-103A-RT?

A: Both components are manufactured by onsemi, share identical product status (obsolete), moisture sensitivity level (MSL 1), and regulatory classifications (REACH Unaffected, EAR99). These parameters establish substitution eligibility within the onsemi component ecosystem.

Q: Are there package compatibility concerns between these parts?

A: Yes. The TCC-103A-RT uses a 16-CSP (2.1x1.9mm) package, while the TCC-303A-RT uses a 12-WLCSP (1.38x1.03mm) package. PCB footprint design and layout must be verified for compatibility before implementation.

Q: Do both parts have the same regulatory compliance status?

A: Yes. Both components are REACH Unaffected, classified as EAR99, and share the same HTSUS code (8542.39.0001), ensuring equivalent regulatory treatment for procurement and deployment.

Q: What should be considered when selecting between these obsolete components?

A: Prioritize current inventory availability, lead time requirements, and PCB layout compatibility. Both parts face similar long-term availability constraints due to obsolete status, making procurement timing and package footprint verification critical factors in component selection.

Q: Are moisture sensitivity and storage requirements identical?

A: Yes. Both components have MSL 1 (Unlimited) classification, indicating identical moisture sensitivity levels and equivalent storage and handling requirements throughout the component lifecycle.
