SR201A102KAT Equivalent & Substitute Parts

Part Overview

The SR201A102KAT is a 1000 pF ±10% 100V ceramic capacitor manufactured by KYOCERA AVX in the SkyCap® SR series. This radial through-hole component operates across -55°C to 125°C with C0G/NP0 temperature coefficient stability, suitable for general-purpose applications requiring stable capacitance across temperature variations. The part is currently active and ROHS3 compliant. Equivalent and substitute parts are identified based on matching or superior electrical and mechanical parameters within the same functional category.

Substitute Part Grouping Explanation

Substitution eligibility for the SR201A102KAT is determined by the following criteria:

Primary Matching Parameters:

Capacitance value: 1000 pF (exact match required)
Voltage rating: 100V minimum (equal or higher acceptable)
Temperature coefficient: C0G/NP0 (required for stability equivalence)
Mounting type: Through hole radial configuration
Operating temperature range: -55°C to 125°C minimum

Secondary Compatibility Factors:

Tolerance: ±10% or tighter (tighter tolerances are acceptable upgrades)
Lead spacing: 0.100" (2.54mm) standard or compatible spacing
RoHS compliance: ROHS3 required
Physical dimensions: Radial package footprint compatibility

Substitute parts are grouped into three categories: direct equivalents (same tolerance and packaging), upgraded tolerance variants (tighter tolerance specifications), and alternative manufacturer options (different manufacturers with equivalent electrical performance).

Engineering Selection Recommendations

Direct Equivalents (Same Tolerance, Same Footprint): SR201A102JAA and SR201A102JAR are direct functional equivalents with ±5% tolerance, matching the SR201A102KAT footprint (0.200" x 0.125", 0.100" lead spacing). Both are active products with ROHS3 compliance and bulk packaging. These parts are suitable for direct substitution where tighter tolerance is acceptable.

Upgraded Tolerance Variants (Tighter Tolerance, Same Footprint): SR201A102GARTR1 offers ±2% tolerance in the same physical footprint as the main part, available in cut tape packaging. This variant provides improved capacitance stability while maintaining identical lead spacing and dimensions. Suitable for applications requiring higher precision.

Compact Footprint Alternatives (Smaller Package): SR151A102JAA, C315C102F1G5TA, C315C102G1G5TA, and C315C102J1G5TA feature reduced physical dimensions (0.150" x 0.100" or 3.81mm x 2.54mm) with 0.100" lead spacing. These parts are suitable for space-constrained designs where the smaller radial package is compatible with PCB layout. All are active products with ROHS3 compliance.

Alternative Manufacturer Options: KEMET GoldMax 300 Comm C0G series (C315C102F1G5TA, C315C102G1G5TA, C315C102J1G5TA, C315C102J1G5TA7301) provides equivalent electrical performance with low ESL characteristics. Available in tolerance grades from ±1% to ±5%, these parts are active and ROHS3 compliant. The cut tape variant C315C102J1G5TA7301 offers highest inventory availability (17,415 pcs).

Lead Spacing Consideration: SR211A102KARTR1 features 0.200" (5.08mm) lead spacing with formed kinked leads, differing from the standard 0.100" spacing. This part is suitable only for designs with compatible PCB hole spacing and is available in cut tape packaging.

Obsolescence Status: FK18C0G2A102JN020 from TDK Corporation is marked "Not For New Designs" and should not be selected for new product development despite electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can SR201A102JAA replace SR201A102KAT directly? A: Yes. SR201A102JAA matches all critical parameters: 1000 pF capacitance, 100V rating, C0G/NP0 temperature coefficient, -55°C to 125°C operating range, and 0.100" lead spacing. The ±5% tolerance is tighter than the ±10% specification, making it functionally compatible. Physical footprint is identical (0.200" x 0.125").

Q: What is the difference between KYOCERA AVX and KEMET substitutes? A: Both manufacturers produce 1000 pF 100V C0G/NP0 radial capacitors meeting the same electrical specifications. KEMET GoldMax 300 Comm C0G series includes low ESL features. Physical dimensions differ: KYOCERA AVX SR201 series is 0.200" x 0.125", while KEMET C315C series is 0.150" x 0.100". Both are ROHS3 compliant and active products.

Q: Are compact footprint parts (SR151A102JAA, C315C series) pin-compatible? A: Yes, all maintain 0.100" (2.54mm) lead spacing, which is standard for radial through-hole capacitors. However, physical body dimensions are smaller (0.150" x 0.100" vs. 0.200" x 0.125"). PCB layout compatibility depends on available space around the component location. Verify clearance before substitution.

Q: Why is FK18C0G2A102JN020 marked "Not For New Designs"? A: This TDK Corporation part is in obsolescence phase. While electrically equivalent, it should not be selected for new product development. Use active alternatives from KYOCERA AVX or KEMET instead.

Q: What tolerance should I select for my application? A: Tolerance selection depends on circuit requirements. The original SR201A102KAT specifies ±10%. Tighter tolerances (±5%, ±2%, ±1%) are available as upgrades and provide improved capacitance stability. Select based on circuit sensitivity to capacitance variation.

Q: Does packaging type (Bulk vs. Cut Tape) affect electrical performance? A: No. Bulk and cut tape packaging contain identical components. Packaging selection is based on assembly process requirements and inventory management. Bulk packaging is typical for manual assembly or reel-fed automated lines; cut tape is used for specific automated assembly equipment.

Q: Can I use SR211A102KARTR1 with different lead spacing? A: SR211A102KARTR1 features 0.200" (5.08mm) lead spacing compared to the standard 0.100" spacing of SR201A102KAT. This part is compatible only with PCB designs that accommodate the wider spacing. Verify hole pattern compatibility before substitution.
