5SR104MCSCA Equivalent & Substitute Parts

Part Overview

The 5SR104MCSCA is a 0.1 µF ceramic capacitor rated for 1000V (1kV) with Y5U temperature coefficient, manufactured by KYOCERA AVX. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The Y5U dielectric material and radial disc package configuration define the functional requirements for equivalent replacement components.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5SR104MCSCA is determined by the following critical parameters:

• Capacitance Value: Must be 0.1 µF
• Voltage Rating: Must be rated for 1000V (1kV) minimum
• Mounting Configuration: Through-hole radial package with straight leads
• Lead Spacing: Physical compatibility with 10.00mm nominal spacing
• Dielectric Type: Y5U or equivalent high-voltage ceramic dielectric acceptable

The substitute part SV07AC104KAR meets these core requirements while offering improved specifications in tolerance (±10% vs. ±20%) and temperature coefficient stability (X7R vs. Y5U), with an extended operating temperature range of -55°C ~ 125°C.

Parameter Comparison

Engineering Selection Recommendations

The SV07AC104KAR is the primary substitute for the obsolete 5SR104MCSCA based on the following factors:

• Product Status: SV07AC104KAR is active and currently manufactured, ensuring long-term availability and supply chain continuity.
• Electrical Equivalence: Both components share identical capacitance (0.1 µF) and voltage rating (1000V), meeting core functional requirements.
• Compliance: SV07AC104KAR carries ROHS3 compliance certification, supporting modern regulatory requirements.
• Lead Spacing Consideration: The substitute features 12.10mm lead spacing versus the original 10.00mm. PCB layout verification is required to confirm mechanical compatibility with existing footprints.
• Dielectric Improvement: X7R temperature coefficient provides superior capacitance stability across the operating temperature range compared to Y5U, with an extended lower temperature limit (-55°C vs. -30°C).

Frequently Asked Questions (FAQ)

Q: Can SV07AC104KAR be used as a direct drop-in replacement for 5SR104MCSCA?

A: Electrical substitution is valid. However, the lead spacing differs (12.10mm vs. 10.00mm), requiring PCB layout verification before implementation. Physical board modifications may be necessary.

Q: What is the significance of the temperature coefficient change from Y5U to X7R?

A: X7R provides tighter capacitance tolerance across temperature variations (±15% maximum change from -55°C to 125°C) compared to Y5U (±15% maximum change from -30°C to 125°C). X7R offers superior stability for precision applications.

Q: Why is tolerance improved from ±20% to ±10% in the substitute?

A: The SV07AC104KAR uses tighter manufacturing specifications, reducing capacitance variation. This provides better circuit performance and reduced design margin requirements.

Q: Are there compatibility concerns with the different package dimensions?

A: The substitute maintains radial disc configuration and through-hole mounting. The primary difference is lead spacing (12.10mm vs. 10.00mm). Verify PCB hole spacing and trace routing before design implementation.

Q: What certifications apply to the substitute part?

A: SV07AC104KAR is ROHS3 compliant and carries REACH Unaffected status, meeting current environmental and regulatory standards.
