Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The KX112-1042-PR is classified as Obsolete. The KXTJ3-1057 maintains Active product status, providing assurance of continued manufacturer support, availability through authorized distribution channels, and compliance with current regulatory standards.

Compliance and Certification: Both parts share identical Moisture Sensitivity Level (MSL 3, 168 Hours) ratings, ensuring equivalent handling and storage requirements during manufacturing and assembly processes. The KXTJ3-1057 carries ROHS3 Compliant and REACH Unaffected certifications, meeting current environmental and regulatory requirements. The KXTJ3-1057 is classified under ECCN EAR99, providing clear export control status.

Package Consideration: The KX112-1042-PR uses a 16-LGA package, while the KXTJ3-1057 uses a 12-LGA (2x2) package. PCB layout modifications are required to accommodate the different pin count and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Why is the KX112-1042-PR listed as Obsolete? A: Obsolete classification indicates the manufacturer has discontinued production and support for this part number. This status typically reflects end-of-life decisions by the manufacturer and necessitates identification of active alternative components.

Q: Can the KXTJ3-1057 directly replace the KX112-1042-PR without design changes? A: No. The KXTJ3-1057 uses a 12-LGA (2x2) package compared to the 16-LGA package of the KX112-1042-PR. PCB layout and schematic modifications are required to accommodate the different pin configuration and physical footprint.

Q: Are the Moisture Sensitivity Level requirements identical between these parts? A: Yes. Both the KX112-1042-PR and KXTJ3-1057 are rated at MSL 3 (168 Hours), ensuring equivalent handling, storage, and assembly process requirements.

Q: What is the difference in regulatory compliance between these parts? A: The KXTJ3-1057 carries current certifications including ROHS3 Compliant and REACH Unaffected status. The KX112-1042-PR, being obsolete, does not carry current compliance documentation. The KXTJ3-1057 is classified under ECCN EAR99, providing defined export control parameters.

Q: Is the KXTJ3-1057 available in the same packaging options as the KX112-1042-PR? A: The KXTJ3-1057 is available in Cut Tape (CT) and Digi-Reel® packaging formats. The original packaging format of the KX112-1042-PR is not specified in the provided parameters.

Q: What inventory status should be considered when selecting between these parts? A: The KX112-1042-PR has 717 pieces in current stock. The KXTJ3-1057 has 195,552 pieces in stock, providing significantly greater availability and supply chain security for ongoing production requirements.
