5SR104MCSIA Equivalent & Substitute Parts

Part Overview

The 5SR104MCSIA is a 0.1 µF ceramic capacitor rated for 1000V (1kV) with Y5U temperature coefficient, designed for through-hole radial mounting in general-purpose applications. This part is classified as obsolete, making identification of suitable alternatives necessary for ongoing design support and procurement continuity. The Y5U dielectric material provides stable performance within its specified temperature range of -30°C to 125°C, with a tolerance of ±20%.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5SR104MCSIA is determined by the following critical parameters:

• Capacitance Value: Must be 0.1 µF
• Voltage Rating: Must be 1000V (1kV) or higher
• Mounting Type: Must be through-hole radial configuration
• Lead Spacing: Must accommodate 0.394" (10.00mm) or compatible spacing
• Dielectric Type: Y5U or equivalent high-voltage ceramic dielectric acceptable

The primary substitute identified is the SV07AC104KAR, which maintains the same capacitance and voltage rating while offering an active product status. This part uses X7R dielectric material, which provides improved temperature stability and tighter tolerance (±10% versus ±20%), along with an extended operating temperature range of -55°C to 125°C.

Parameter Comparison

Engineering Selection Recommendations

The SV07AC104KAR is the primary substitute for the obsolete 5SR104MCSIA. Both parts are manufactured by KYOCERA AVX and share identical capacitance and voltage ratings. The substitute offers the following advantages:

• Active Product Status: The SV07AC104KAR is currently in active production, ensuring long-term availability and supply chain stability.
• Improved Tolerance: ±10% tolerance provides tighter capacitance control compared to the ±20% tolerance of the original part.
• Extended Temperature Range: Operating range of -55°C to 125°C exceeds the original -30°C to 125°C specification.
• RoHS3 Compliance: The substitute meets current environmental and regulatory requirements.
• Regulatory Alignment: Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

The primary consideration is lead spacing: the substitute has 0.476" (12.10mm) spacing versus the original 0.394" (10.00mm). PCB layout verification is required to confirm compatibility with existing hole patterns.

Frequently Asked Questions (FAQ)

Q: Can the SV07AC104KAR be used as a direct replacement for the 5SR104MCSIA?

A: The SV07AC104KAR is functionally equivalent in terms of capacitance, voltage rating, and mounting type. However, the lead spacing differs (12.10mm versus 10.00mm), requiring PCB layout assessment before implementation.

Q: What is the difference between Y5U and X7R dielectric materials?

A: Y5U dielectric provides stable performance within -30°C to 125°C with ±20% tolerance. X7R dielectric extends the operating range to -55°C to 125°C with improved ±10% tolerance. X7R is suitable for applications requiring wider temperature operation and tighter capacitance control.

Q: Why is the 5SR104MCSIA classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The SV07AC104KAR represents the current active equivalent from the same manufacturer.

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

A: The SV07AC104KAR includes ROHS3 Compliant certification, meeting current environmental standards. Both parts maintain REACH Unaffected status and EAR99 classification.

Q: What should be verified before implementing the substitute?

A: PCB hole spacing must accommodate the 12.10mm lead spacing of the SV07AC104KAR. Thermal performance requirements should be evaluated against the extended -55°C to 125°C operating range. Circuit design should confirm that ±10% tolerance is acceptable for the application.
