Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped into three categories based on electrical and mechanical parameter alignment with the main part CL43B474KBFNNNF:

Parametric Equivalent: Parts with identical electrical specifications (0.47 µF, ±10%, 50V, X7R) and mechanical compatibility (1812 package, same dimensions). These parts are direct functional replacements with no performance trade-offs.

Direct Manufacturer Equivalents: Parts from alternative manufacturers meeting all electrical parameters and package requirements. Substitution is based on matching capacitance, voltage rating, tolerance, temperature coefficient, and physical package dimensions.

Upgrade Parts: Parts with enhanced specifications (tighter tolerance ±5% or higher voltage rating 100V) while maintaining the same capacitance value, temperature coefficient, and 1812 package form factor. These parts provide improved performance margins and are backward compatible.

Key parameters determining substitution eligibility:

• Capacitance: 0.47 µF (fixed requirement)
• Temperature Coefficient: X7R (fixed requirement)
• Package / Case: 1812 (4532 Metric) (fixed requirement)
• Mounting Type: Surface Mount, MLCC (fixed requirement)
• Operating Temperature: -55°C ~ 125°C (fixed requirement)
• Voltage Rating: 50V minimum (50V or higher acceptable)
• Tolerance: ±10% or tighter (±10% or ±5% acceptable)

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original CL43B474KBFNNNF specification. MSL 1 rating is consistent across all parts, indicating unlimited shelf life without moisture sensitivity constraints.

Direct Substitutes (No Performance Change): CL43B474KBFNNNE, C1812C474K5RAC7800, and KGM43AR71H474KV are electrically and mechanically equivalent to the main part. These parts are suitable for direct replacement in applications where the original 0.47 µF ±10% 50V X7R specification is required.

Tolerance-Enhanced Substitutes: C1812C474J5RAC7800 and KGM43AR71H474JV provide ±5% tolerance instead of ±10%, offering tighter capacitance accuracy. These parts are backward compatible and suitable for applications requiring improved tolerance performance while maintaining 50V rating.

Voltage-Enhanced Substitutes: C1812C474K1RAC7800 and KGM43FR72A474KV provide 100V rating instead of 50V, offering increased voltage margin. These parts are backward compatible for 50V applications and suitable for designs requiring higher voltage headroom. Note that increased voltage rating results in greater thickness (0.065" to 0.087" maximum).

All substitute parts are available in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CL43B474KBFNNNE be used as a direct replacement for CL43B474KBFNNNF?

A: Yes. CL43B474KBFNNNE is a parametric equivalent from Samsung Electro-Mechanics with identical electrical specifications (0.47 µF ±10% 50V X7R) and mechanical dimensions (1812 package, 4.50mm x 3.20mm). The difference is packaging format (Cut Tape & Digi-Reel vs. standard packaging). Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the KEMET C1812C474K5RAC7800 and the KYOCERA AVX KGM43AR71H474KV?

A: Both parts are direct equivalents with matching 0.47 µF ±10% 50V X7R specifications and 1812 package dimensions. The primary difference is manufacturer and thickness: KEMET C1812C474K5RAC7800 has 0.043" (1.10mm) maximum thickness, while KYOCERA AVX KGM43AR71H474KV has 0.055" (1.40mm) maximum thickness. Selection depends on available PCB space and manufacturer preference.

Q: Can I use C1812C474J5RAC7800 (±5% tolerance) instead of the original ±10% part?

A: Yes. C1812C474J5RAC7800 provides tighter tolerance (±5%) while maintaining all other specifications (0.47 µF, 50V, X7R, 1812 package). This part is backward compatible and suitable for applications where improved capacitance accuracy is beneficial. No circuit redesign is required.

Q: What are the advantages of using C1812C474K1RAC7800 or KGM43FR72A474KV with 100V rating?

A: These parts provide higher voltage margin (100V vs. 50V) while maintaining the same capacitance (0.47 µF) and temperature coefficient (X7R). They are backward compatible for 50V applications and suitable for designs requiring increased voltage headroom or operating in higher voltage environments. Trade-off: increased thickness (0.065" to 0.087" maximum) requires verification of available PCB space.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original CL43B474KBFNNNF specification.

Q: What packaging formats are available for substitute parts?

A: Substitute parts are available in Tape & Reel (TR) format, suitable for automated pick-and-place assembly. The original part CL43B474KBFNNNF uses standard packaging. Verify packaging compatibility with your assembly process requirements.

Q: Can I mix different manufacturers (Samsung, KEMET, KYOCERA AVX) in the same PCB assembly?

A: Yes. All substitute parts meet identical electrical specifications (0.47 µF ±10% 50V X7R) and mechanical requirements (1812 package, -55°C ~ 125°C operating range). Mixing manufacturers is acceptable from an electrical and mechanical standpoint. Verify with your quality and procurement procedures for any internal requirements.
