Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 12065C502MAT2A is determined by the following critical parameters:

• Capacitance Value: Must be 5000 pF
• Voltage Rating: Must be 50V or higher
• Temperature Coefficient: Must be X7R for stable performance across the operating temperature range
• Package / Case: Must be 1206 (3216 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 0.126" L x 0.063" W (3.20mm x 1.60mm) and 0.037" (0.94mm) maximum thickness

The substitute part 12065C502JAT2A meets all these criteria. The primary difference is the tolerance specification: the substitute offers ±5% tolerance compared to the original part's ±20% tolerance. This represents an upgrade in capacitance accuracy while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 12065C502MAT2A and 12065C502JAT2A are active products from KYOCERA AVX with identical compliance certifications (ROHS3 compliant, REACH unaffected). Both components are rated for the same voltage, temperature range, and package specifications.

The 12065C502JAT2A offers improved capacitance tolerance (±5% versus ±20%), which provides tighter control over actual capacitance values. This upgrade is suitable for applications where capacitance accuracy is a design requirement. The substitute part maintains full compatibility with the original part's mechanical footprint, thermal characteristics, and regulatory compliance status.

Selection between these parts should be based on the specific tolerance requirements of the application circuit. If ±20% tolerance is acceptable, the original part remains valid. If tighter tolerance control is needed, the substitute part is the appropriate choice.

Frequently Asked Questions (FAQ)

Q: Can the 12065C502JAT2A directly replace the 12065C502MAT2A in existing designs?

A: Yes. Both parts share identical electrical ratings (5000 pF, 50V, X7R), operating temperature range (-55°C to 125°C), and mechanical specifications (1206 package, 0.126" x 0.063" x 0.037" max). The substitute part is a direct mechanical and electrical replacement.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. The original part (12065C502MAT2A) has ±20% tolerance, while the substitute (12065C502JAT2A) has ±5% tolerance. This means the substitute provides tighter control over the actual capacitance value delivered.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across -55°C to 125°C with X7R temperature coefficient, ensuring stable capacitance performance throughout this range.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level), making them suitable for standard assembly and storage without special handling.

Q: Can I use the substitute part in high-precision applications?

A: The ±5% tolerance of the substitute part (12065C502JAT2A) provides improved accuracy compared to the ±20% tolerance of the original part. Applications requiring tighter capacitance control should use the substitute part.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in the 1206 (3216 Metric) case with identical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.037" (0.94mm). They are footprint-compatible.
