Equivalent & Substitute Parts for M22G182J2 Ceramic Capacitor

Part Overview

The M22G182J2 is a 1800 pF ceramic capacitor manufactured by Cornell Dubilier Electronics (CDE) with a rated voltage of 200V and C0G/NP0 temperature coefficient. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates across a temperature range of -55°C to 125°C and is designed for general-purpose through-hole mounting in radial configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M22G182J2 is based on the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Capacitance value must equal 1800 pF
• Temperature coefficient must be C0G or NP0
• Operating temperature range must encompass -55°C to 125°C
• Rated voltage must be equal to or greater than 200V
• Tolerance must be equal to or tighter than ±5%

Mechanical Compatibility Criteria:

• Mounting type must be Through Hole
• Package configuration must be Radial
• Lead spacing must be 0.200" (5.08mm)
• Lead style must be Straight

All three substitute parts from KEMET meet these criteria. The substitutes are from the GoldMax 300 Comm C0G series and feature improved voltage ratings (250V) and tighter tolerances (±1% and ±2% options available), while maintaining identical capacitance, temperature coefficient, and mechanical footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Electrical and Mechanical Equivalence):

C330C182JAG5TA is the direct functional equivalent to M22G182J2. Both components share identical capacitance (1800 pF), tolerance (±5%), temperature coefficient (C0G/NP0), and mechanical footprint (0.200" lead spacing, radial configuration). The KEMET substitute provides superior voltage rating (250V versus 200V) and is currently in active production with ROHS3 compliance, addressing the obsolescence of the original CDE part.

For Enhanced Performance Requirements:

C330C182GAG5TA and C330C182FAG5TA offer tighter tolerance specifications (±2% and ±1% respectively) while maintaining all other electrical and mechanical parameters. These options are suitable for applications requiring improved capacitance accuracy without circuit redesign.

Compliance Consideration:

All three KEMET substitutes are ROHS3 compliant and REACH unaffected, whereas the original M22G182J2 is RoHS non-compliant. Selection of substitute parts aligns with current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can C330C182JAG5TA directly replace M22G182J2 in existing circuit boards?

A: Yes. Both components have identical lead spacing (0.200"), radial package configuration, and straight lead style. The footprint is mechanically compatible for through-hole mounting. Electrical parameters (1800 pF capacitance, ±5% tolerance, C0G/NP0 temperature coefficient, -55°C to 125°C operating range) are functionally equivalent.

Q: What is the advantage of the 250V rating on KEMET substitutes compared to the 200V original?

A: The higher voltage rating provides additional safety margin in the circuit. A 250V-rated capacitor can be used in applications designed for 200V operation without derating. This does not change the component's electrical behavior at the original 200V specification.

Q: Are the ±1% and ±2% tolerance options interchangeable with the ±5% original?

A: Yes, from a substitution standpoint. Tighter tolerances (±1% and ±2%) are superior to ±5% and will function in any circuit designed for ±5% tolerance. However, circuit performance may differ if the design relies on the capacitance value being at the upper or lower tolerance limit of ±5%.

Q: Does the physical size difference affect PCB layout?

A: The lead spacing remains identical at 0.200" (5.08mm), ensuring hole-to-hole compatibility. The KEMET parts are slightly larger in body dimensions (0.280" L x 0.160" W versus 0.200" L x 0.150" W for the original), but this does not affect through-hole mounting compatibility. Verify available PCB clearance around the component footprint.

Q: Why is RoHS compliance important for this substitution?

A: RoHS3 compliance ensures the substitute parts meet current environmental and safety regulations for electronic components. The original M22G182J2 is RoHS non-compliant, making ROHS3-compliant substitutes necessary for new designs and manufacturing processes subject to regulatory requirements.

Q: Can these substitutes be used in high-reliability or military applications?

A: Substitution decisions for high-reliability or military applications must be based on specific qualification requirements beyond the parameters provided. Consult application-specific standards and manufacturer datasheets for such use cases.
