M22R103K2 Equivalent & Substitute Parts

Part Overview

The M22R103K2 is a 10000 pF ±10% 200V ceramic capacitor with X7R temperature coefficient manufactured by Cornell Dubilier Electronics (CDE) in radial through-hole configuration. This part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and production requirements. The M22 series radial ceramic capacitor remains functionally relevant for general-purpose applications despite its discontinued status. Equivalent parts maintain identical electrical specifications, while substitute parts offer enhanced performance characteristics or improved compliance status.

Substitute Part Grouping Explanation

Substitute parts for the M22R103K2 are categorized into three groups based on electrical and mechanical compatibility:

Direct Equivalents maintain identical electrical specifications (10000 pF, ±10%, 200V, X7R) with compatible physical dimensions and lead spacing. These parts provide drop-in replacement capability with no circuit redesign required.

Upgraded Substitutes offer enhanced voltage ratings (250V or 500V), improved temperature coefficients (C0G/NP0 instead of X7R), or extended operating temperature ranges (-55°C ~ 200°C). These parts are suitable when circuit design permits higher voltage ratings or when improved temperature stability is beneficial. Upgraded substitutes may have different physical dimensions but maintain the critical 0.200" (5.08mm) lead spacing for PCB compatibility.

Similar Alternatives employ different temperature coefficient designations (BX instead of X7R) or military-grade specifications while maintaining core electrical parameters. These parts address high-reliability applications or specialized environmental requirements.

Substitution logic is based strictly on:

Capacitance value (10000 pF)
Voltage rating (minimum 200V)
Tolerance (±10% or tighter)
Lead spacing (0.200" / 5.08mm)
Mounting configuration (through-hole radial)

Frequently Asked Questions (FAQ)

Q: Can MR052C103KAA be used as a direct replacement for M22R103K2?

A: Yes. MR052C103KAA maintains identical electrical specifications (10000 pF, ±10%, 200V, X7R, -55°C ~ 125°C) and the required 0.200" lead spacing. Physical dimensions differ slightly (0.190" L x 0.090" W versus 0.200" L x 0.150" W), but this does not affect PCB compatibility when lead spacing is preserved. MR052C103KAA is an active product with current manufacturing support.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R temperature coefficient specifies capacitance variation of ±15% across the -55°C ~ 125°C operating range. C0G/NP0 temperature coefficient specifies capacitance variation of ±30 ppm/°C, providing superior stability across temperature extremes. C0G/NP0 is preferred for precision applications requiring minimal capacitance drift with temperature changes.

Q: Can I use a 250V or 500V rated capacitor in a 200V circuit?

A: Yes. Voltage rating specifies the maximum voltage the capacitor can withstand. Using a capacitor with a higher voltage rating than required is acceptable and does not degrade performance. ARR07L103KGA (500V) and C330C103JAG5TA (250V) are suitable for 200V circuits.

Q: What is the significance of RoHS compliance status?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the part does not contain restricted materials such as lead, cadmium, or hexavalent chromium. ROHS3-compliant parts (C330C103 series) meet current environmental regulations and are required for many commercial and consumer applications. Non-compliant parts (M22R103K2, MR052C103KAA, ARR07L103KGA, VRR07L103KGS, CK06BX103K) may be restricted in certain markets or applications.

Q: Does lead spacing affect PCB compatibility?

A: Yes. All recommended substitutes maintain the critical 0.200" (5.08mm) lead spacing, ensuring compatibility with PCB layouts designed for the M22R103K2. Physical body dimensions may vary, but lead spacing determines hole-to-hole distance on the PCB and must remain constant.

Q: What packaging options are available?

A: MR052C103KAA is supplied in bulk packaging. MR062C103KAATR2 is supplied in tape & reel (TR) format for automated assembly. Bulk packaging is suitable for manual assembly or small-volume production. Tape & reel packaging is optimized for high-volume automated assembly processes.

Q: Are there inventory considerations for part selection?

A: Current inventory levels are provided for reference. MR052C103KAA (963 pcs), MR062C103KAATR2 (945 pcs), and C330C103J2G5TA (4139 pcs) have substantial stock availability. Inventory levels should be verified with suppliers for production planning purposes, as availability may change.

Q: What is the difference between ARR07L103KGA and VRR07L103KGS?

A: Both parts are 10000 pF, ±10%, 500V, X7R ceramic capacitors with -55°C ~ 200°C operating range. ARR07L103KGA is designated for standard industrial applications. VRR07L103KGS is designated for high-voltage, high-temperature applications with enhanced performance characteristics. Both maintain 0.200" lead spacing and are suitable for 200V circuits.

Q: Can CK06BX103K be used in place of M22R103K2?

A: CK06BX103K maintains identical capacitance (10000 pF), tolerance (±10%), voltage (200V), and operating temperature range (-55°C ~ 125°C) with 0.200" lead spacing. The BX temperature coefficient differs from X7R, providing different temperature stability characteristics. CK06BX103K is qualified to military standard MIL-C-11015 and is suitable for high-reliability applications. Substitution is acceptable when military-grade specifications are required or beneficial.
