Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6SQ102MEASA is determined by the following critical parameters:

• Capacitance Value: Must be 1000 pF
• Voltage Rating: Must be 500V or higher
• Mounting Configuration: Must be through-hole radial with straight leads
• Package Type: Must be radial disc configuration
• Temperature Coefficient: X5U or equivalent performance class acceptable

The substitute part D102K25Y5PL63L6R meets these core electrical and mechanical requirements. While the temperature coefficient differs (Y5P vs. X5U), both are standard ceramic capacitor classifications suitable for general-purpose applications within the specified voltage and capacitance range.

Parameter Comparison

Engineering Selection Recommendations

The D102K25Y5PL63L6R is a suitable substitute for the obsolete 6SQ102MEASA based on the following factors:

• Electrical Equivalence: Both components share identical capacitance (1000 pF) and voltage rating (500V), meeting the primary functional requirements.
• Product Availability: The substitute is classified as active with substantial inventory (18,470 pcs), ensuring supply continuity for the obsolete original part.
• Compliance Status: Both components are REACH Unaffected and classified as EAR99, maintaining regulatory alignment.
• Tolerance Improvement: The substitute offers tighter tolerance (±10% vs. ±20%), providing enhanced precision in applications where capacitance stability is critical.
• Physical Compatibility: Both use through-hole radial configuration with straight leads. The substitute has slightly larger physical dimensions (0.256" vs. 0.157" diameter) and marginally different lead spacing (0.250" vs. 0.236"), which must be verified against PCB layout constraints.
• Temperature Performance: The substitute operates across -30°C to 125°C, which covers the upper portion of the original range. Applications requiring operation below -30°C require design review.

Frequently Asked Questions (FAQ)

Q: Can D102K25Y5PL63L6R be used as a direct replacement for 6SQ102MEASA?

A: Yes, for applications where the operating temperature range does not extend below -30°C and PCB layout accommodates the larger physical dimensions (0.256" diameter vs. 0.157"). Verify lead spacing compatibility with existing through-hole patterns before implementation.

Q: What is the difference between X5U and Y5P temperature coefficients?

A: X5U and Y5P are distinct ceramic capacitor temperature coefficient classifications defined by IEC standards. Both are suitable for general-purpose applications. X5U provides wider temperature range (-55°C to 125°C), while Y5P operates from -30°C to 125°C. Selection depends on the specific thermal environment of the application.

Q: Does the tighter tolerance of the substitute affect circuit performance?

A: The substitute's ±10% tolerance is tighter than the original ±20%, which generally improves circuit stability and predictability. This is beneficial for most applications and does not introduce compatibility issues.

Q: Are there physical mounting considerations when substituting?

A: Yes. The substitute is larger in diameter (6.50mm vs. 4.00mm) and has slightly different lead spacing (6.35mm vs. 6.00mm). Verify that the PCB layout and component placement accommodate these dimensional differences before soldering.

Q: What compliance certifications apply to both parts?

A: Both components are REACH Unaffected and classified under ECCN EAR99, with HTSUS code 8532.23.0060. The substitute additionally carries RoHS3 compliance certification.
