Substitute Part Grouping Explanation

Substitution for the AQ142M431KAJME is determined by strict equivalence across the following critical parameters:

• Capacitance value: 430 pF (exact match required)
• Voltage rating: 200V (minimum requirement)
• Temperature coefficient: M (frequency stability characteristic)
• Operating temperature range: -55°C ~ 125°C (thermal performance envelope)
• Package / Case: 1111 (2828 Metric) (physical and electrical footprint compatibility)
• Mounting type: Surface Mount, MLCC (assembly process compatibility)
• Physical dimensions: 0.110" L x 0.110" W, 0.102" max thickness (PCB layout fit)

Tolerance variations (±10% vs. ±5%) are permitted substitutions when the tighter tolerance does not create design conflicts. Both substitute parts maintain identical capacitance, voltage, temperature coefficient, operating range, package, and physical dimensions as the original component.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are manufactured by KYOCERA AVX and maintain active product status, ensuring long-term availability and supply chain stability compared to the obsolete AQ142M431KAJME.

SQCB2M431JAJME\500 (Upgrade): This part offers improved tolerance specification (±5% vs. ±10%), providing tighter capacitance control. Selection of this upgrade is appropriate for applications requiring enhanced frequency stability and reduced component variation. Both parts share identical electrical and physical specifications across all other parameters.

SQCB2M431KAJME\500 (Parametric Equivalent): This part maintains the original ±10% tolerance specification while providing active product status. Selection of this equivalent is appropriate for direct replacement in existing designs without tolerance-related design modifications.

Both substitute parts comply with identical regulatory certifications (RoHS non-compliant, REACH Unaffected, ECCN EAR99, HTSUS 8532.24.0020) and environmental classifications (MSL 1 - Unlimited) as the original component.

Frequently Asked Questions (FAQ)

Q: Can SQCB2M431JAJME\500 or SQCB2M431KAJME\500 be used as direct replacements for AQ142M431KAJME?

A: Yes. Both substitute parts are direct replacements. They maintain identical capacitance (430 pF), voltage rating (200V), temperature coefficient (M), operating temperature range (-55°C ~ 125°C), package (1111 / 2828 Metric), and physical dimensions (0.110" L x 0.110" W, 0.102" max thickness). The primary difference is product status (active vs. obsolete) and, in the case of SQCB2M431JAJME\500, improved tolerance specification.

Q: What is the difference between the two substitute parts?

A: SQCB2M431JAJME\500 provides ±5% tolerance, while SQCB2M431KAJME\500 provides ±10% tolerance. All other electrical and physical parameters are identical. The tolerance difference determines capacitance control precision; tighter tolerance (±5%) is suitable for applications requiring enhanced frequency stability.

Q: Are there any compliance or regulatory differences between the original and substitute parts?

A: No. All three parts share identical RoHS status (non-compliant), REACH status (Unaffected), ECCN classification (EAR99), HTSUS code (8532.24.0020), and Moisture Sensitivity Level (MSL 1 - Unlimited).

Q: Will the substitute parts fit the same PCB footprint?

A: Yes. Both substitute parts use the identical 1111 (2828 Metric) package with dimensions of 0.110" L x 0.110" W and maximum thickness of 0.102" (2.59mm), ensuring compatibility with existing PCB layouts and assembly processes.

Q: Why is the original AQ142M431KAJME obsolete?

A: The AQ series has been superseded by the SQ series from KYOCERA AVX. The SQ series maintains equivalent electrical and physical specifications while offering active product status and improved availability.
