Equivalent & Substitute Parts for 6SQ102MAASA

Part Overview

The 6SQ102MAASA is a 1000 pF ceramic capacitor rated at 500V with X5U temperature coefficient, manufactured by KYOCERA AVX in a radial, disc configuration. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The radial through-hole mounting and general-purpose application profile allow for direct substitution with compatible alternatives meeting the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6SQ102MAASA 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: Must support the operating temperature range of -55°C to 125°C

The substitute part D102K25Y5PL63L6R meets these core electrical and mechanical requirements. While the temperature coefficient differs (Y5P versus X5U), the operating temperature range of -30°C to 125°C encompasses the critical upper temperature limit and maintains functional compatibility for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

The D102K25Y5PL63L6R is an active, in-production substitute for the obsolete 6SQ102MAASA. Selection of this substitute is supported by:

• Electrical Equivalence: Identical capacitance (1000 pF) and voltage rating (500V) ensure functional compatibility in circuit applications
• Mechanical Compatibility: Both components feature radial disc configuration with straight leads suitable for through-hole PCB mounting
• Improved Tolerance: The ±10% tolerance of the substitute provides tighter capacitance control compared to the ±20% tolerance of the original part
• Regulatory Compliance: The substitute carries ROHS3 compliance certification, meeting current environmental and material restriction standards
• Availability: Active production status ensures reliable long-term procurement and supply chain continuity

Physical dimensions differ slightly; PCB layout verification is necessary to confirm fit within existing mounting footprints.

Frequently Asked Questions (FAQ)

Q: Can D102K25Y5PL63L6R be used as a direct replacement for 6SQ102MAASA?

A: Yes, for general-purpose applications. Both components share identical capacitance (1000 pF) and voltage rating (500V) with compatible through-hole radial mounting. Physical dimensions differ; verify PCB layout clearance before implementation.

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

A: X5U specifies capacitance change of ±15% over -55°C to 125°C. Y5P (B) specifies ±10% change over -30°C to 125°C. The substitute operates within a narrower lower temperature range but maintains the critical upper temperature limit of 125°C.

Q: Are there any compliance differences between the two parts?

A: The substitute (D102K25Y5PL63L6R) is ROHS3 compliant. The original part (6SQ102MAASA) RoHS status is not specified. Both are REACH unaffected and carry EAR99 ECCN classification.

Q: Will the larger physical dimensions of the substitute cause PCB layout issues?

A: The substitute is 0.099" larger in diameter (6.50mm vs 4.00mm) and has increased lead spacing (6.35mm vs 5.00mm). Verify PCB footprint compatibility and component spacing before design implementation.

Q: What is the tolerance difference, and does it matter?

A: The substitute offers ±10% tolerance versus ±20% for the original. Tighter tolerance provides improved capacitance accuracy, which may benefit circuit performance in applications sensitive to capacitance variation.
