The substitute parts are grouped into two categories:

Upgrade Substitutes (C330C472FAG5TA, C330C472GAG5TA, C330C472JAG5TA): These KEMET components feature higher voltage ratings (250V) and improved tolerance specifications (±1% to ±5%), with active product status and RoHS3 compliance. These parts are direct functional upgrades.

Similar Substitute (C330C472J2G5TA): This KEMET component maintains identical electrical specifications (4700 pF, ±5%, 200V) with active product status and RoHS3 compliance, serving as a direct replacement.

Engineering Selection Recommendations

Direct Replacement (Identical Specifications): C330C472J2G5TA is the primary substitute for M30G472J2. Both components share identical electrical specifications: 4700 pF capacitance, ±5% tolerance, and 200V voltage rating. The KEMET part offers the advantage of active product status and ROHS3 compliance, addressing the obsolescence and regulatory compliance limitations of the original CDE component. Physical dimensions and lead spacing are compatible with existing PCB layouts designed for the M30G472J2.

Upgraded Substitutes (Enhanced Performance): C330C472FAG5TA, C330C472GAG5TA, and C330C472JAG5TA are suitable for applications where higher voltage margin or improved tolerance is beneficial. These parts maintain the same capacitance value and temperature coefficient while offering 250V voltage ratings (25% higher than the original 200V specification). Tolerance options range from ±1% to ±5%, allowing selection based on circuit precision requirements. All three parts are ROHS3 compliant and carry active product status.

Compliance Considerations: The original M30G472J2 is RoHS non-compliant. All substitute parts (C330C472J2G5TA, C330C472FAG5TA, C330C472GAG5TA, C330C472JAG5TA) are ROHS3 compliant, meeting current regulatory requirements for new designs and manufacturing operations subject to RoHS directives.

Frequently Asked Questions (FAQ)

Q: Can C330C472J2G5TA be used as a direct replacement for M30G472J2 in existing designs?

A: Yes. C330C472J2G5TA is electrically and mechanically compatible with M30G472J2. Both components have identical capacitance (4700 pF), tolerance (±5%), voltage rating (200V), temperature coefficient (C0G/NP0), and lead spacing (0.200"). The KEMET part is physically smaller (0.280" L x 0.160" W versus 0.300" L x 0.200" W) but maintains the same lead spacing, allowing installation in existing PCB footprints designed for the CDE component.

Q: What is the difference between the three KEMET upgrade options?

A: The three upgrade substitutes differ only in tolerance specification and voltage rating. C330C472FAG5TA offers ±1% tolerance, C330C472GAG5TA offers ±2% tolerance, and C330C472JAG5TA offers ±5% tolerance. All three are rated for 250V (compared to 200V for the original part). Select based on circuit tolerance requirements: ±1% for precision applications, ±2% for general-purpose applications requiring tighter control, or ±5% for standard applications matching the original specification.

Q: Are the physical dimensions of substitute parts compatible with the original PCB layout?

A: The substitute parts are physically smaller than the original M30G472J2. The M30G472J2 measures 0.300" L x 0.200" W with a maximum seated height of 0.420", while all KEMET substitutes measure 0.280" L x 0.160" W with a maximum seated height of 0.360". However, all parts maintain the same 0.200" (5.08mm) lead spacing, which is the critical dimension for PCB footprint compatibility. The smaller size of substitute parts allows installation in existing footprints without modification.

Q: What is the significance of the C0G/NP0 temperature coefficient for this application?

A: C0G/NP0 temperature coefficient indicates negligible capacitance change across the operating temperature range (-55°C to 125°C). This specification is critical for applications requiring stable capacitance performance independent of temperature variations. All substitute parts maintain this specification, ensuring equivalent performance in temperature-sensitive circuits.

Q: Why should I select an upgrade substitute with higher voltage rating?

A: Higher voltage ratings provide additional safety margin in circuits operating near the component's rated voltage. A 250V-rated capacitor in a 200V circuit offers 25% voltage headroom, reducing stress on the dielectric and potentially extending component life. Upgrade substitutes are appropriate for designs where voltage transients or margin requirements justify the higher rating.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts (C330C472J2G5TA, C330C472FAG5TA, C330C472GAG5TA, C330C472JAG5TA) are ROHS3 compliant. The original M30G472J2 is RoHS non-compliant. For new designs or manufacturing operations subject to RoHS directives, substitute parts are required.
