Parameter Comparison

Engineering Selection Recommendations

For Obsolescence Management: The KXTKK-1102 is obsolete and should not be selected for new designs. The KXTJ3-1057 is the active equivalent and is the appropriate choice for production applications.

For Supply Chain Continuity: The KXTJ3-1057 has 195,552 units in stock compared to 951 units of the KXTKK-1102, providing significantly greater availability and reducing procurement risk.

For Regulatory Compliance: The KXTJ3-1057 carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements. The KXTKK-1102 does not specify these certifications.

For Moisture Handling: Both parts share identical MSL ratings, eliminating the need for process changes in storage, handling, or reflow procedures.

Frequently Asked Questions (FAQ)

Q: Can the KXTJ3-1057 be used as a direct replacement for the KXTKK-1102?

A: Yes. Both parts are manufactured by Kionix Inc., share identical LGA packaging technology, and have matching MSL ratings. The KXTJ3-1057 is the designated substitute for the obsolete KXTKK-1102.

Q: What is the difference in package size between these parts?

A: The KXTJ3-1057 is specified as 12-LGA (2x2), indicating a 12-pin land grid array in a 2mm x 2mm footprint. The KXTKK-1102 package dimensions are not detailed in the provided specifications.

Q: Are there any compliance differences between the two parts?

A: The KXTJ3-1057 is certified as ROHS3 Compliant and REACH Unaffected. The KXTKK-1102 does not specify these certifications. For applications requiring regulatory compliance, the KXTJ3-1057 is the appropriate selection.

Q: What are the moisture handling requirements for these parts?

A: Both parts carry an MSL rating of 3 (168 Hours), requiring identical moisture control procedures during storage and assembly. No process modifications are necessary when transitioning from KXTKK-1102 to KXTJ3-1057.

Q: Why should the KXTKK-1102 not be used in new designs?

A: The KXTKK-1102 is classified as obsolete and is no longer in active production. Using obsolete components in new designs creates long-term supply chain risk and limits access to technical support. The KXTJ3-1057 is the active equivalent and is the recommended choice for all new applications.

Q: Is the KXTJ3-1057 available in the same packaging options as the KXTKK-1102?

A: The KXTJ3-1057 is available in Cut Tape (CT) and Digi-Reel® packaging formats. The KXTKK-1102 packaging format is not specified in the provided data.
