Substitute Part Grouping Explanation
Substitution eligibility for the M20R104K5-F is determined by strict equivalence across the following critical parameters:
Mandatory Matching Parameters:
- Capacitance: 0.1 µF
- Tolerance: ±10%
- Voltage Rating: 50V
- Temperature Coefficient: X7R
- Operating Temperature Range: -55°C to 125°C
- Mounting Type: Through Hole
- Package Type: Radial
- Lead Spacing: 0.100" (2.54mm)
- RoHS Compliance: ROHS3 Compliant
Allowable Variations:
- Physical dimensions (length, width, height) may vary within PCB layout constraints
- Lead style (straight or formed leads) may differ based on assembly requirements
- Packaging format (bulk, cut tape) does not affect electrical equivalence
- Manufacturer and series designation are not substitution criteria
All substitute parts listed meet these mandatory electrical and mechanical requirements and are therefore direct functional equivalents for the M20R104K5-F.

Engineering Selection Recommendations
Primary Substitutes (Active Product Status):
KEMET C320C104K5R5TA and C320C104K5R5TA7301 are the preferred substitutes. Both maintain identical electrical specifications and lead spacing to the M20R104K5-F. The C320C104K5R5TA7301 variant is available in cut tape packaging, suitable for automated assembly environments. Both parts are active products with full manufacturer support and ROHS3 compliance.
Secondary Substitutes (Active Product Status):
KEMET C324C104K5R5TA and C326C104K5R5TA offer electrical equivalence with formed-lead configurations. These parts accommodate applications requiring kinked leads for specific PCB mounting geometries. Both maintain active product status and ROHS3 compliance.
Vishay Beyschlag K104K10X7RF53L2, K104K10X7RF55K2, K104K15X7RF53K2, and K104K15X7RF53L2 provide functional equivalence with compact form factors. These parts feature 0.098" lead spacing (versus 0.100" on the original) and are suitable for space-constrained applications. All variants are active products with ROHS3 compliance.
Not Recommended for New Designs:
TDK FK18X7R1H104KN020 meets all electrical requirements but carries "Not For New Designs" status. This part is suitable only for maintenance and repair of existing equipment using the original component.
Compliance Verification:
All recommended substitutes are ROHS3 compliant and operate within the -55°C to 125°C temperature range specified for the M20R104K5-F. Moisture sensitivity level 1 (unlimited) is maintained across all active substitutes.
Frequently Asked Questions (FAQ)
Q: Can I substitute the M20R104K5-F with any of the listed parts?
A: All listed parts meet the mandatory electrical and mechanical parameters (0.1 µF, ±10%, 50V, X7R, -55°C to 125°C, 0.100" or 0.098" lead spacing, through-hole radial package). However, verify PCB layout compatibility, particularly for parts with 0.098" lead spacing or different physical dimensions. TDK FK18X7R1H104KN020 is not recommended for new designs.
Q: What is the difference between KEMET C320C104K5R5TA and C320C104K5R5TA7301?
A: Both parts are electrically identical. The primary difference is packaging: C320C104K5R5TA is supplied in bulk, while C320C104K5R5TA7301 is supplied in cut tape format. Select based on assembly process requirements.
Q: Why do some substitutes have 0.098" lead spacing instead of 0.100"?
A: Lead spacing is a mechanical parameter that does not affect electrical function. Vishay Beyschlag Mono-Kap K series components use 0.098" spacing. Verify PCB pad spacing before selection to ensure mechanical compatibility.
Q: Are all substitute parts ROHS3 compliant?
A: All active and recommended substitute parts listed are ROHS3 compliant. The TDK FK18X7R1H104KN020 is also ROHS3 compliant but carries "Not For New Designs" status.
Q: What is the difference between straight leads and formed leads?
A: Straight leads are perpendicular to the capacitor body. Formed leads (kinked) are bent at an angle for specific PCB mounting geometries. Both configurations are electrically equivalent; selection depends on PCB layout requirements.
Q: Can I use these substitutes in high-temperature applications?
A: All substitute parts operate across -55°C to 125°C, matching the M20R104K5-F specification. X7R temperature coefficient ensures stable capacitance across this range. Verify application requirements do not exceed these limits.
Q: What inventory considerations should I evaluate?
A: KEMET C320C104K5R5TA7301 has 11,872 units in stock. KEMET C320C104K5R5TA has 130,162 units available. Vishay K104K15X7RF53L2 has 46,084 units in stock. Evaluate lead times and supply chain requirements for your production schedule.
