Engineering Selection Recommendations

KYOCERA AVX Direct Equivalents (Same Series, Packaging Variants): SR211C102KAA and SR211C102KAR are direct bulk packaging alternatives with identical electrical specifications and 0.200" lead spacing. Both feature reduced seated height (0.200") compared to the original SR211C102KAT (0.300"). SR211C102KARTR1 maintains the original 0.300" height in cut tape packaging with significantly higher inventory availability (20428 Pcs).

KYOCERA AVX Compact Variants (Reduced Footprint): SR151C102KAR and SR151C102KARTR1 are manufacturer-recommended alternatives with compact dimensions (0.150" L x 0.100" W, 0.100" lead spacing). These are suitable for space-constrained applications while maintaining all electrical parameters. Available in both bulk and cut tape formats.

Cross-Manufacturer Substitutes (KEMET): C317C102K1R5TA and C322C102K1R5TA from KEMET's GoldMax 300 Comm X7R series provide equivalent electrical performance. C317C102K1R5TA matches the compact footprint (0.150" L x 0.100" W) with 0.200" lead spacing. C322C102K1R5TA matches standard dimensions (0.200" L x 0.125" W) with 0.260" seated height. Both are ROHS3 compliant with high inventory levels.

Cross-Manufacturer Substitutes (Murata Electronics): RDER72A102K0K1H03B (bulk) and RDER72A102K0M1H03A (cut tape) from Murata's RDE series meet all electrical specifications with compact dimensions (0.157" L x 0.098" W, 0.197" lead spacing). Both are ROHS3 compliant alternatives suitable for general-purpose applications.

All listed substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original SR211C102KAT.

Frequently Asked Questions (FAQ)

Q: Can SR151C102KAR replace SR211C102KAT directly on a PCB? A: SR151C102KAR is electrically equivalent but has a reduced footprint (0.100" lead spacing vs. 0.200"). Direct replacement requires PCB layout modification. The compact dimensions make it suitable for space-constrained designs while maintaining all electrical parameters.

Q: What is the difference between bulk and cut tape packaging? A: Bulk packaging (Tape & Reel) is suitable for manual assembly or small-volume production. Cut Tape (CT) packaging provides pre-cut strips for automated pick-and-place equipment. Electrical specifications are identical; packaging choice depends on assembly process requirements.

Q: Are KEMET C317C102K1R5TA and C322C102K1R5TA interchangeable with KYOCERA AVX parts? A: Both KEMET parts match all electrical specifications (1000 pF, ±10%, 100V, X7R, -55°C to 125°C) and are ROHS3 compliant. C317C102K1R5TA has compact dimensions; C322C102K1R5TA has standard dimensions. Mechanical compatibility depends on PCB layout and lead spacing requirements.

Q: What is the significance of lead spacing differences (0.100", 0.197", 0.200")? A: Lead spacing determines PCB hole pattern compatibility. Parts with 0.100" spacing require compact PCB layouts. Parts with 0.197" or 0.200" spacing fit standard through-hole patterns. Selection depends on existing PCB design and available space.

Q: Can Murata RDER72A102K0K1H03B be used in applications designed for SR211C102KAT? A: Electrical specifications are identical. The Murata part has slightly different dimensions (0.157" L x 0.098" W vs. 0.200" L x 0.125" W) and 0.197" lead spacing vs. 0.200". PCB layout compatibility must be verified before substitution.

Q: Are all listed parts suitable for -55°C to 125°C operating range? A: All listed substitutes operate across -55°C to 125°C with X7R temperature coefficient, matching the original SR211C102KAT specification.

Q: What inventory considerations apply to these substitutes? A: SR211C102KARTR1 offers the highest availability (20428 Pcs). KEMET C322C102K1R5TA provides 9215 Pcs. Murata parts have lower inventory (1101-1339 Pcs). Selection should consider supply chain requirements and lead time constraints.
