Substitute Part Grouping Explanation

Substitute parts for the 08052C472KAT9A are classified into two categories based on electrical parameter compatibility:

Direct Equivalents (Identical Electrical Specifications): Parts matching all primary electrical parameters—4700 pF capacitance, ±10% tolerance, 200V voltage rating, and X7R temperature coefficient—with identical package and mounting specifications. These parts are interchangeable without circuit redesign.

Upgrade Substitutes (Enhanced Electrical Specifications): Parts with improved electrical characteristics while maintaining the same capacitance, temperature coefficient, and package form factor. Upgrades include higher voltage ratings (250V) or tighter tolerance (±5%), providing enhanced performance margins. These parts are electrically compatible and may be used as direct replacements in applications where the enhanced specifications do not conflict with circuit design constraints.

Key Parameters Determining Substitution:

Capacitance value: 4700 pF (fixed)
Temperature coefficient: X7R (fixed)
Package: 0805 (2012 Metric) (fixed)

Engineering Selection Recommendations

Direct Equivalent Selection: For applications requiring exact electrical and mechanical compatibility with the 08052C472KAT9A, select from C0805C472K2RAC7800 (KEMET) or CL21B472KDCNNNC (Samsung Electro-Mechanics). Both parts maintain identical capacitance, tolerance, voltage rating, and temperature coefficient specifications. All three parts (including the primary part) are ROHS3 compliant, REACH unaffected, and carry MSL rating 1. KEMET C0805C472K2RAC7800 offers the highest inventory availability (96633 units) and minimal thickness variation (0.88mm vs. 0.94mm primary specification).

Upgrade Substitute Selection: For applications where enhanced performance margins are acceptable, C0805C472J2RAC7800 (KEMET, ±5% tolerance, 200V) provides tighter capacitance tolerance while maintaining the original voltage rating. For circuits tolerating higher voltage ratings, C0805C472KARAC7800 (KEMET, 250V, ±10% tolerance) or C2012X7R2E472K085AA (TDK, 250V, ±10% tolerance) offer increased voltage headroom. All upgrade substitutes maintain active production status and full compliance certifications.

Avoid for New Designs: GRM21AR72E472KW01D (Murata Electronics) carries "Not For New Designs" status and should not be selected for new circuit development, despite meeting electrical specifications and maintaining adequate inventory.

Thickness Consideration: If PCB assembly height constraints are critical, KEMET parts (C0805C472K2RAC7800, C0805C472J2RAC7800, C0805C472KARAC7800) offer the thinnest profile at 0.035" (0.88mm). KGM21AR72E472JU exhibits the maximum thickness at 0.057" (1.45mm) and should be avoided in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 250V-rated capacitor in place of the 200V-rated 08052C472KAT9A?

A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible. The circuit will function identically. Select from C0805C472KARAC7800, C2012X7R2E472K085AA, or KGM21AR72E472JU for 250V options.

Q: What is the difference between ±10% and ±5% tolerance substitutes?

A: Tolerance specifies the allowable deviation from the nominal 4700 pF capacitance value. ±10% allows 4230–5170 pF; ±5% allows 4465–4935 pF. Tighter tolerance (±5%) is beneficial in precision circuits but not required for general-purpose applications. C0805C472J2RAC7800 and KGM21AR72E472JU offer ±5% tolerance.

Q: Are all substitute parts in the same 0805 package?

A: Yes. All listed substitutes use the 0805 (2012 Metric) package and are surface-mount compatible. Physical dimensions are 0.079" L × 0.049" W (2.00–2.01mm × 1.25mm). Thickness varies slightly (0.035–0.057") but does not affect package classification or PCB footprint compatibility.

Q: Which substitute has the best inventory availability?

A: CL21B472KDCNNNC (Samsung Electro-Mechanics) offers the highest inventory at 286071 units, followed by C2012X7R2E472K085AA (TDK, 135727 units) and C0805C472KARAC7800 (KEMET, 93427 units).

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed parts, including the primary 08052C472KAT9A, are ROHS3 compliant and REACH unaffected. MSL rating is 1 (Unlimited) for all parts, indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use KGM21AR72E472JU as a direct replacement?

A: KGM21AR72E472JU is electrically compatible but differs in tolerance (±5% vs. ±10%) and thickness (1.45mm vs. 0.94mm). It is suitable for applications where tighter tolerance and higher voltage (250V) are beneficial, but the increased thickness may conflict with space-constrained designs.

Q: Why is GRM21AR72E472KW01D marked "Not For New Designs"?

A: This designation indicates the manufacturer (Murata Electronics) is discontinuing the product line. While currently in stock and functionally equivalent, it should not be selected for new circuit development to avoid future supply chain disruption.
