Engineering Selection Recommendations
Primary Substitutes (Recommended for New Designs):
The KEMET C322C104K1R5TA series (C322C104K1R5TA, C322C104K1R5TA7301, C322C104K1R5TA7303) represents the optimal substitution path. These parts maintain exact electrical equivalence with the M22R104K1-F while offering active product status from a qualified manufacturer. The C322C series is available in multiple packaging formats (Bulk, Cut Tape) to accommodate various procurement workflows. All variants are ROHS3 compliant and carry REACH Unaffected status.
Secondary Substitutes (Active Production):
The Vishay Beyschlag/Draloric/BC Components Mono-Kap™ K series (K104K20X7RH53H5, K104K20X7RH5TH5, K104K20X7RH5UH5, K104K20X7RH5UK5) provides full electrical equivalence with minor lead spacing tolerance variation (0.197" versus 0.200"). These components are actively manufactured and available in bulk and tape formats. The kinked lead style variants accommodate automated assembly processes.
Alternative Substitute (Legacy Status):
The Murata Electronics RDE series (RDER72A104K1K1H03B, RDER72A104K1M1H03A) delivers complete electrical and mechanical compatibility with active production status. These parts feature kinked formed leads and compact physical dimensions suitable for high-density PCB layouts.
Not Recommended for New Designs:
The TDK Corporation FK24X7R2A104KN000 carries "Not For New Designs" status and should be avoided for new product development, though it remains electrically and mechanically compatible with the M22R104K1-F.
Frequently Asked Questions (FAQ)
Q: Can I directly replace M22R104K1-F with any of the listed substitutes without PCB modification?
A: Yes, all listed substitutes are mechanically and electrically compatible with the M22R104K1-F. The radial through-hole package and 0.200" (5.08mm) lead spacing are maintained across KEMET variants. Vishay and Murata parts feature 0.197" (5.00mm) lead spacing, which falls within standard PCB footprint tolerances for radial components and requires no PCB redesign.
Q: What is the difference between the KEMET C322C104K1R5TA packaging options?
A: The C322C104K1R5TA is supplied in Bulk packaging for general procurement. The C322C104K1R5TA7301 and C322C104K1R5TA7303 variants are identical electrically and mechanically but supplied in Cut Tape (CT) format for automated pick-and-place assembly. Selection depends on manufacturing process requirements rather than component performance.
Q: Are all substitutes ROHS3 compliant?
A: Yes, all listed substitute parts are ROHS3 compliant, matching the environmental compliance status of the M22R104K1-F.
Q: Why is the TDK FK24X7R2A104KN000 marked "Not For New Designs"?
A: This designation indicates the manufacturer has discontinued active promotion of this part for new product development. While electrically and mechanically equivalent, KEMET, Vishay, and Murata alternatives are preferred for new designs due to their active production status and long-term availability commitment.
Q: What is the difference between straight leads and formed leads?
A: The M22R104K1-F features straight leads, while most substitutes use formed leads (some kinked). Both lead styles are compatible with standard through-hole PCB assembly. Formed leads may provide improved mechanical retention during wave soldering, while straight leads offer flexibility for manual insertion and rework operations.
Q: Can I mix different substitute manufacturers in the same circuit board?
A: Yes, all substitutes meet identical electrical specifications (0.1 µF ±10% 100V X7R) and operating temperature range (-55°C to 125°C). Mixing manufacturers within the same design is electrically and mechanically valid.
Q: What inventory levels are available for each substitute?
A: KEMET C322C104K1R5TA (Bulk): 5,172 pcs; C322C104K1R5TA7301 (CT): 1,593 pcs; C322C104K1R5TA7303 (CT): 5,635 pcs. Vishay K104K20X7RH5UH5: 31,172 pcs. Murata RDER72A104K1K1H03B: 51,700 pcs. TDK FK24X7R2A104KN000: 1,995 pcs. Inventory levels support both prototype and production-volume requirements.
