Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CL43B474KBFNNNE is determined by the following critical parameters: capacitance value (0.47 µF), temperature coefficient (X7R), package type (1812/4532 Metric), and physical dimensions (0.177" L x 0.126" W). All substitute parts maintain these core specifications.

Substitute parts are categorized into two groups:

Direct Equivalents maintain identical electrical specifications (0.47 µF ±10% 50V X7R):

• C1812C474K5RAC7800 (KEMET)
• KGM43AR71H474KV (KYOCERA AVX)

Upgraded Alternatives offer enhanced specifications while maintaining the same package and core parameters:

• C1812C474J5RAC7800 (KEMET): Tighter tolerance (±5% vs ±10%)
• C1812C474K1RAC7800 (KEMET): Higher voltage rating (100V vs 50V)
• KGM43AR71H474JV (KYOCERA AVX): Tighter tolerance (±5% vs ±10%)
• KGM43FR72A474KV (KYOCERA AVX): Higher voltage rating (100V vs 50V)

All substitute parts are ROHS3 compliant, REACH unaffected, and classified as Active product status.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active product status with ROHS3 compliance and REACH unaffected certification, meeting the same regulatory requirements as the primary part CL43B474KBFNNNE.

Direct Equivalent Selection: C1812C474K5RAC7800 (KEMET) and KGM43AR71H474KV (KYOCERA AVX) provide identical electrical specifications (0.47 µF ±10% 50V X7R) with full pin-to-pin compatibility and identical package dimensions. These parts are suitable for direct substitution in existing designs without circuit modification.

Upgraded Alternative Selection: Parts with ±5% tolerance (C1812C474J5RAC7800, KGM43AR71H474JV) offer improved capacitance accuracy for applications requiring tighter component tolerances. Parts with 100V rating (C1812C474K1RAC7800, KGM43FR72A474KV) provide increased voltage margin for circuits operating near the 50V specification limit or requiring design headroom.

Physical thickness variations exist among substitute parts (ranging from 0.043" to 0.087"), which must be evaluated against PCB layout constraints and available board space. All parts maintain the same 1812 (4532 Metric) footprint and surface mount compatibility.

Frequently Asked Questions (FAQ)

Q: Can C1812C474K5RAC7800 replace CL43B474KBFNNNE directly?

A: Yes. C1812C474K5RAC7800 is a direct equivalent with identical capacitance (0.47 µF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), and package dimensions (1812/4532 Metric). No circuit modifications are required.

Q: What is the difference between direct equivalents and upgraded alternatives?

A: Direct equivalents (C1812C474K5RAC7800, KGM43AR71H474KV) maintain all original specifications. Upgraded alternatives offer either tighter tolerance (±5% vs ±10%) or higher voltage rating (100V vs 50V) while preserving the same capacitance value and package type.

Q: Can I use a 100V rated capacitor in place of the 50V rated CL43B474KBFNNNE?

A: Yes. Higher voltage-rated capacitors (C1812C474K1RAC7800, KGM43FR72A474KV) are electrically compatible and provide additional voltage margin. However, these parts have increased thickness (0.065" to 0.087" vs 0.057"), which must be verified against PCB layout constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of CL43B474KBFNNNE.

Q: What is the significance of thickness variation among substitute parts?

A: Thickness ranges from 0.043" (KEMET parts) to 0.087" (KYOCERA AVX 100V part). PCB design must accommodate the selected part's maximum thickness to ensure proper component placement and clearance from adjacent board features.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part offers the best tolerance specification?

A: C1812C474J5RAC7800 (KEMET) and KGM43AR71H474JV (KYOCERA AVX) both offer ±5% tolerance, compared to ±10% for the original part and other direct equivalents.
