Engineering Selection Recommendations

For Direct Electrical Equivalence (Same Specifications): Select KGM21NR71H152KT (KYOCERA AVX), 0805B152K500CT (Walsin), C0805C152K5RAC7800 (KEMET), or CC0805KRX7R9BB152 (YAGEO). All maintain 1500 pF ±10% 50V X7R specifications with identical electrical performance. All substitute options are ROHS3 Compliant and REACH Unaffected, addressing compliance gaps in the original part.

For Improved Tolerance and Temperature Stability: Select KGM21BCG1H152FT (±1%), KGM21BCG1H152GT (±2%), or KGM21BCG1H152KT (±10%) from the KYOCERA AVX KGM C0G/NP0 series. These provide superior temperature coefficient stability with tighter tolerance specifications while maintaining 50V rating and 0805 package. All are ROHS3 Compliant.

For Higher Voltage Margin: Select KGM21NR72A152JT (100V, ±5%), KGM21NR72A152KT (100V, ±10%), or KGM21NR72D152KT (200V, ±10%) from the KYOCERA AVX KGM X7R series. These maintain identical capacitance and tolerance with elevated voltage ratings for applications requiring higher voltage headroom. All are ROHS3 Compliant.

Compliance Consideration: The original 08055C152KA12A is RoHS non-compliant. All listed substitute parts are ROHS3 Compliant and REACH Unaffected, making them suitable for applications with regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 08055C152KA12A with a higher voltage rated part such as KGM21NR72A152KT (100V)?

A: Yes. Higher voltage ratings are electrically compatible substitutes. The 100V rated part operates within the same temperature range (-55°C ~ 125°C) and maintains identical 1500 pF capacitance and ±10% tolerance. The higher voltage rating provides additional safety margin without affecting circuit performance at 50V operation.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change over the -55°C ~ 125°C temperature range. C0G/NP0 provides superior stability with ±0.3% capacitance change over the same range. C0G/NP0 parts (KGM21BCG1H152FT, KGM21BCG1H152GT, KGM21BCG1H152KT) are suitable for applications requiring tighter capacitance tolerance across temperature variations.

Q: Are the KYOCERA AVX KGM series parts direct replacements?

A: KGM21NR71H152KT is a direct replacement with identical electrical specifications (1500 pF ±10% 50V X7R). KGM21BCG1H152KT is functionally equivalent with improved temperature coefficient (C0G/NP0). KGM21NR72A152KT and KGM21NR72D152KT are compatible substitutes with higher voltage ratings.

Q: Can I use parts from different manufacturers (Walsin, KEMET, YAGEO) interchangeably?

A: Yes. 0805B152K500CT (Walsin), C0805C152K5RAC7800 (KEMET), and CC0805KRX7R9BB152 (YAGEO) all meet the same electrical specifications (1500 pF ±10% 50V X7R 0805 package) and are mechanically compatible. All are ROHS3 Compliant and suitable for direct substitution.

Q: Does package thickness variation affect compatibility?

A: The original part specifies 0.037" (0.94mm) maximum thickness. Substitute parts range from 0.024" to 0.039" maximum thickness. All variations remain within standard 0805 package mechanical constraints and are compatible with standard PCB assembly equipment and design layouts.

Q: What is the inventory advantage of selecting substitute parts?

A: The original 08055C152KA12A has 945 Pcs in stock. Substitute options offer significantly higher availability: KGM21BCG1H152GT (146193 Pcs), CC0805KRX7R9BB152 (73781 Pcs), C0805C152K5RAC7800 (47361 Pcs), and KGM21NR71H152KT (36105 Pcs), reducing lead time risk.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 Compliant. The original 08055C152KA12A is RoHS non-compliant. Substitution addresses regulatory compliance requirements for applications subject to RoHS directives.
