Key Parameters

Substitute Part Grouping Explanation

Substitution of the KX124-1051-PR is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Manufacturer alignment (Kionix Inc.)
• Motion sensor category classification
• Moisture sensitivity level compatibility (MSL 3)
• Active product status for continued availability

The KXTJ3-1057 qualifies as a substitute based on manufacturer continuity within the Kionix product line, shared MSL rating, and active production status. Both components are surface-mount accelerometers designed for motion sensing applications.

Note: The KX124-1051-PR operates as a 16-pin package, while the KXTJ3-1057 utilizes a 12-pin package. Circuit board layout modifications are required for physical implementation.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The KX124-1051-PR is obsolete and no longer manufactured. The KXTJ3-1057 is an active product with confirmed inventory availability (195,552 units in stock), ensuring long-term supply chain reliability.

Compliance Status: The KXTJ3-1057 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. Export classification is EAR99, indicating standard commercial component status.

Moisture Sensitivity Alignment: Both components share MSL 3 (168 Hours) rating, indicating equivalent handling and storage requirements during manufacturing and assembly processes.

Physical Integration: Circuit redesign is required due to package footprint differences (16-pin to 12-pin configuration). PCB layout modifications and pinout verification are necessary before implementation.

Frequently Asked Questions (FAQ)

Q: Can the KXTJ3-1057 directly replace the KX124-1051-PR without circuit modifications?

A: No. The KXTJ3-1057 uses a 12-pin package (12-VFLGA) while the KX124-1051-PR uses a 16-pin package (16-LGA). Pinout differences require circuit board redesign and schematic verification.

Q: Are the moisture sensitivity requirements identical between these components?

A: Yes. Both components carry MSL 3 (168 Hours) rating, indicating equivalent moisture sensitivity levels and identical handling protocols during manufacturing and storage.

Q: What is the supply status difference between these parts?

A: The KX124-1051-PR is obsolete with no ongoing production. The KXTJ3-1057 is an active product with 195,552 units currently in stock, providing assured availability for new designs and production runs.

Q: Does the KXTJ3-1057 meet current regulatory requirements?

A: Yes. The KXTJ3-1057 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Are both components manufactured by the same company?

A: Yes. Both the KX124-1051-PR and KXTJ3-1057 are manufactured by Kionix Inc., ensuring design philosophy and quality standards alignment within the product family.

Q: What packaging options are available for the KXTJ3-1057?
