Substitute Part Grouping Explanation

Substitution of the KX023-1025-01 is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Manufacturer alignment (Kionix Inc.)
• Product category (Motion Sensors)
• Functional classification (Accelerometer)
• Active product status for continued support and availability

The KXTJ3-1057 qualifies as a direct substitute based on these parameters. Both components are accelerometers manufactured by Kionix Inc. and operate within the motion sensor category. The KXTJ3-1057 maintains an Active product status, ensuring manufacturer support, documentation, and supply chain continuity.

Compatibility Basis: The substitution is established through the manufacturer's own designation of KXTJ3-1057 as the equivalent replacement for KX023-1025-01, as indicated in the provided substitute parts list.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The KXTJ3-1057 is the designated equivalent for the obsolete KX023-1025-01. Selection of this substitute is supported by the following factors:

1. Product Status Alignment: The KXTJ3-1057 maintains Active product status, ensuring ongoing manufacturer support, technical documentation, and supply availability. This contrasts with the KX023-1025-01's Obsolete classification.

2. Regulatory Compliance: The KXTJ3-1057 carries ROHS3 Compliant and REACH Unaffected certifications, meeting current environmental and regulatory requirements. These certifications support long-term design validity and market acceptance.

3. Moisture Sensitivity Equivalence: Both components share identical MSL ratings of 3 (168 Hours), ensuring equivalent handling and storage requirements during manufacturing and assembly processes.

4. Export Classification: The KXTJ3-1057 is classified under ECCN EAR99, providing clear export control status for international supply chain planning.

Design Transition Considerations:

Physical package differences exist between the KX023-1025-01 (16LGA) and KXTJ3-1057 (12-LGA 2x2). PCB layout and footprint modifications are required for implementation. The KXTJ3-1057 introduces digital output via I2C interface and selectable acceleration ranges (±2g, 4g, 8g, 16g), which may require firmware or signal processing adjustments in the host system.

Frequently Asked Questions (FAQ)

Q: Why is the KX023-1025-01 listed as Obsolete?

A: The KX023-1025-01 has reached end-of-life status and is no longer manufactured or actively supported by Kionix Inc. Existing inventory remains available, but no new production is planned. The KXTJ3-1057 represents the current-generation replacement.

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

A: No. The KX023-1025-01 uses a 16-pin LGA package, while the KXTJ3-1057 uses a 12-pin LGA (2x2) package. PCB redesign and footprint modification are required. Pin assignments and signal definitions differ between the two components.

Q: What are the key differences in functionality between these parts?

A: The KXTJ3-1057 is a digital accelerometer with I2C output and selectable acceleration ranges (±2g, 4g, 8g, 16g). The KX023-1025-01 specifications are not fully detailed in the provided parameters. Functional validation against your specific application requirements is necessary.

Q: Are the moisture sensitivity levels compatible?

A: Yes. Both components carry an MSL rating of 3 (168 Hours), indicating identical moisture sensitivity classifications and equivalent handling requirements during manufacturing and assembly.
