Substitute Part Grouping Explanation

Substitution eligibility for the M30R224K5-F is determined by strict electrical and mechanical parameter matching. All substitute parts must satisfy the following criteria:

Electrical Requirements:

Capacitance: 0.22 µF (exact match)
Voltage Rating: 50V (minimum)
Tolerance: ±10% (acceptable)
Temperature Coefficient: X7R (exact match for temperature stability across -55°C to 125°C)

Mechanical Requirements:

Mounting Type: Through Hole Radial (PCB assembly compatibility)
Lead Spacing: 0.200" (5.08mm) nominal (PCB hole pattern compatibility)
Lead Style: Straight or Formed Leads (both acceptable for through-hole insertion)
Package/Case: Radial (exact match)

Compliance Requirements:

RoHS3 Compliant (regulatory requirement)
ECCN: EAR99 (export classification match)
HTSUS: 8532.24.0060 (tariff classification match)

Physical dimensions (length, width, height) may vary within acceptable limits provided lead spacing remains 0.200" (5.08mm) and the component fits standard through-hole PCB footprints. Product status (Active vs. Obsolete/Not For New Designs) does not disqualify electrical equivalence but affects long-term availability.

Frequently Asked Questions (FAQ)

Q: Can I substitute the M30R224K5-F with any of these parts directly without PCB modification?

A: KEMET C322C224K5R5TA and C330C224K5R5TA feature identical 0.200" (5.08mm) lead spacing and require no PCB modification. Vishay Mono-Kap™ K series and Murata RDE series parts have 0.197" (5.00mm) lead spacing and require PCB hole pattern verification. TDK FK series also use 0.197" (5.00mm) spacing. Verify your PCB design specifications before selection.

Q: What is the difference between the KEMET C322C224K5R5TA and C330C224K5R5TA?

A: Both parts are electrically identical with 0.22 µF ±10% 50V X7R specifications and 0.200" (5.08mm) lead spacing. Physical dimensions differ slightly: C322C is 0.200" L x 0.125" W with 0.260" seated height; C330C is 0.280" L x 0.160" W with 0.360" seated height. Selection depends on available PCB space. C330C has higher inventory availability (3304 pcs vs. 11520 pcs for C322C).

Q: Why do some substitute parts have "Not For New Designs" status?

A: TDK FK series components are classified as Not For New Designs, indicating the manufacturer has discontinued active development and marketing of these products. While electrically equivalent and currently in stock, these parts should be used only for maintenance and repair of existing systems. New product designs should utilize Active status components such as KEMET, Vishay, or Murata alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the original M30R224K5-F specification. This ensures regulatory compliance for applications subject to RoHS directives.

Q: What is the significance of lead spacing differences (0.200" vs. 0.197")?

A: Lead spacing determines PCB hole pattern compatibility. The original M30R224K5-F uses 0.200" (5.08mm) spacing. KEMET parts maintain this spacing for direct substitution. Vishay, Murata, and TDK parts use 0.197" (5.00mm) spacing, a 0.03mm variance. Verify your PCB design accommodates this tolerance before selection. Most modern PCB designs with standard 0.1" grid spacing accommodate both specifications, but verification is required.

Q: Which substitute offers the best long-term availability?

A: KEMET C330C224K5R5TA and Vishay K224K20X7RF5TH5 offer the highest current inventory levels (3304 pcs and 44169 pcs respectively) and Active product status, indicating ongoing manufacturing and supply chain support. These parts are recommended for new designs requiring long-term component availability.

Q: Can I mix different substitute parts in the same design?

A: Yes. All listed substitute parts are electrically and functionally equivalent with identical capacitance, voltage, tolerance, and temperature coefficient specifications. Physical dimension variations do not affect electrical performance. However, maintain consistent lead spacing within a single PCB design to avoid assembly complications.

Q: What packaging options are available?

A: KEMET parts are supplied in Bulk packaging. Vishay Mono-Kap™ K series offers both Bulk (K224K20X7RF53H5, K224K20X7RF5WH5) and Cut Tape (K224K20X7RF5TH5, K224K20X7RF5UH5) options. Murata RDE series offers Bulk (RDER71H224K1K1H03B) and Cut Tape (RDER71H224K1M1H03A) packaging. Select packaging based on production volume and assembly requirements.
