SR201A331FAA Equivalent & Substitute Parts

Part Overview

The SR201A331FAA is a 330 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 100V with C0G/NP0 temperature coefficient and ±1% tolerance. This radial through-hole component is classified as Active product status and is suitable for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component flexibility.

Substitute Part Grouping Explanation

Substitution eligibility for the SR201A331FAA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage rating: 100V (minimum requirement; higher ratings acceptable)
• Temperature coefficient: C0G or NP0 (functionally equivalent designations)
• Operating temperature range: -55°C to 125°C (minimum requirement)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.100" (2.54mm) (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (maintained across substitutes)

The KEMET C315C331F1G5TA meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the SR201A331FAA and C315C331F1G5TA are Active product status components with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability, lead time, and packaging format (KYOCERA AVX supplies in standard packaging; KEMET supplies in bulk packaging). Both components satisfy identical electrical and mechanical requirements for through-hole PCB assembly applications.

Frequently Asked Questions (FAQ)

Q: Can the C315C331F1G5TA replace the SR201A331FAA in existing designs?

A: Yes. Both components share identical electrical specifications (330 pF, ±1%, 100V, C0G/NP0) and mechanical compatibility (radial through-hole, 0.100" lead spacing). No circuit redesign is required.

Q: Are there physical size differences between these parts?

A: The SR201A331FAA has a body dimension of 0.200" L x 0.125" W (5.08mm x 3.18mm) with a maximum seated height of 0.200" (5.08mm). The C315C331F1G5TA has a body dimension of 0.150" L x 0.100" W (3.81mm x 2.54mm) with a maximum seated height of 0.183" (4.66mm). Both fit standard 0.100" lead spacing on PCBs; the KEMET part is physically smaller.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the SR201A331FAA and C315C331F1G5TA are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards.

Q: What is the difference between C0G and NP0 designations?

A: C0G and NP0 are functionally equivalent temperature coefficient designations used by different manufacturers. Both indicate zero temperature coefficient performance across the -55°C to 125°C operating range.

Q: Can a higher voltage-rated capacitor be substituted if the 100V part is unavailable?

A: Substitution with higher voltage ratings is acceptable from an electrical standpoint, provided all other parameters (capacitance, tolerance, temperature coefficient, lead spacing, and mounting type) remain identical. Physical dimensions and PCB layout compatibility must be verified.
