Engineering Selection Recommendations

KYOCERA AVX SkyCap® SR Series (Same Manufacturer):

SR211C102KAA and SR211C102KAR provide tolerance improvement from ±20% to ±10% while maintaining 100V rating and X7R characteristics. Both are active products with ROHS3 compliance. Selection between these bulk options depends on packaging format requirements for assembly processes.

SR211C102KARTR1 offers the same electrical specifications as SR211C102KAR with Cut Tape packaging and highest inventory availability (20428 units). This part maintains the original 0.300" maximum height matching the SR211C102MAATR1 profile. Recommended for high-volume production requiring automated tape handling.

SR891C102KARTR1 provides tolerance upgrade with straight lead style instead of kinked leads. Physical dimensions differ slightly (0.215" L vs 0.200" L, 0.260" height vs 0.300" height). Suitable for applications where lead straightness is preferred and PCB layout accommodates the dimensional variation.

KEMET GoldMax 300 Comm X7R Series (Cross-Manufacturer):

C317C102K1R5TA and C322C102K1R5TA both deliver ±10% tolerance at 100V rating with ROHS3 compliance. C317C102K1R5TA features compact 0.150" L x 0.100" W footprint; C322C102K1R5TA matches the original 0.200" L x 0.125" W dimensions. Both are active products suitable for direct substitution where KEMET sourcing is acceptable.

C317C102K2R5TA and C322C102K2R5TA upgrade voltage rating to 200V while maintaining 1000 pF capacitance and ±10% tolerance. These are active products for applications requiring higher voltage margin.

C322C102KFR5TA provides 1500V rating with high-voltage classification. This part is active and suitable for circuits requiring significant voltage headroom beyond the original 100V specification.

TDK Corporation FK Series (Cross-Manufacturer):

FK26X7R2J102KN000 offers 630V rating with ±10% tolerance and X7R stability. This part is marked "Not For New Designs" and should be evaluated only when existing inventory or legacy design requirements mandate TDK sourcing. ROHS3 compliance is maintained.

Product Status Consideration:

All substitute parts except FK26X7R2J102KN000 are classified as Active. The TDK part's "Not For New Designs" status indicates it is in mature phase; use is restricted to maintenance or legacy system support.

Frequently Asked Questions (FAQ)

Q: Can SR211C102KAA replace SR211C102MAATR1 directly?

A: Yes, electrically and mechanically. SR211C102KAA provides tighter tolerance (±10% vs ±20%) at identical 100V rating and X7R temperature coefficient. The primary difference is packaging format (Bulk vs Tape & Reel) and reduced maximum height (0.200" vs 0.300"). Verify PCB assembly equipment compatibility with bulk packaging and confirm the lower profile does not conflict with board layout constraints.

Q: What is the advantage of SR211C102KARTR1 over SR211C102MAATR1?

A: SR211C102KARTR1 maintains identical electrical specifications (1000 pF, ±10%, 100V, X7R) and physical height (0.300" maximum) but uses Cut Tape packaging instead of Tape & Reel. Significantly higher inventory (20428 vs 1074 units) supports extended production runs. Cut Tape format is compatible with most automated pick-and-place systems. Lead style remains kinked, preserving original insertion characteristics.

Q: Are KEMET C322C102K1R5TA and KYOCERA AVX SR211C102MAATR1 pin-compatible?

A: Yes. Both feature 0.200" lead spacing, radial through-hole mounting, and X7R temperature coefficient across -55°C to 125°C. Physical dimensions are compatible: C322C102K1R5TA is 0.200" L x 0.125" W (matching original) with 0.260" maximum height. Tolerance improves to ±10%. Verify solder joint reliability with your assembly process, as KEMET and KYOCERA AVX may have different lead material specifications.

Q: When should I select a higher voltage-rated substitute like C322C102K2R5TA (200V)?

A: Higher voltage ratings provide design margin for circuits subject to transient overvoltage or where supply voltage tolerance stacking creates peak stress conditions. Select 200V or higher ratings only when circuit analysis confirms the benefit outweighs increased component cost and physical size. The original 100V rating is sufficient for applications operating within specified supply limits.

Q: Is FK26X7R2J102KN000 suitable for new designs?

A: No. TDK classifies this part as "Not For New Designs," indicating end-of-life or mature product phase. Use only for replacement in existing systems or when legacy design documentation mandates TDK sourcing. For new designs, select from active products: KYOCERA AVX SkyCap® SR series or KEMET GoldMax 300 Comm X7R series.

Q: What is the difference between formed leads and straight leads?

A: Formed leads (kinked) are pre-bent for insertion into standard PCB holes with automatic lead-forming equipment. Straight leads require manual or specialized equipment for lead forming before insertion. SR891C102KARTR1 uses straight leads; all other substitutes use formed leads. Select based on assembly process capability and whether your equipment includes lead-forming stations.

Q: Can I mix packaging formats (Tape & Reel, Cut Tape, Bulk) in the same production run?

A: Packaging format affects only component delivery and handling, not electrical or mechanical performance. Mixing formats is acceptable if your assembly equipment can process multiple input types. Verify feeder compatibility and operator training for format transitions to prevent assembly errors.
