B37872K2223K062 Equivalent & Substitute Parts

Part Overview

The B37872K2223K062 is a 0.022 µF ±10% 200V ceramic capacitor in 1206 (3216 Metric) surface mount package with X7R temperature coefficient. Manufactured by EPCOS - TDK Electronics, this part is classified as obsolete. Due to its obsolete status and limited availability (983 pcs in stock), identifying equivalent and substitute parts is necessary for design continuity and procurement flexibility. Substitute parts maintain the same electrical specifications while offering active product status and broader availability from alternative manufacturers.

Substitute Part Grouping Explanation

Substitution for the B37872K2223K062 is determined by strict equivalence in the following parameters:

Capacitance: 0.022 µF (exact match required)
Tolerance: ±10% (exact match required)
Voltage Rating: 200V minimum (equal or higher voltage acceptable)
Temperature Coefficient: X7R (exact match required)
Package / Case: 1206 (3216 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)

Engineering Selection Recommendations

For direct replacement of the B37872K2223K062 at 200V rating, select from active product status parts: C1206C223K2RAC7800 (KEMET) with highest inventory (54691 pcs) and smallest thickness (0.035"), or KGM31DR72D223KU (KYOCERA AVX) with substantial inventory (45999 pcs). Both are ROHS3 compliant and MSL 1 rated.

For applications requiring higher voltage margin, upgrade options include C1206C223KARAC7800 (KEMET, 250V, ±10%, 9937 pcs) or C3216X7R2J223K130AA (TDK, 630V, ±10%, 55488 pcs). The 250V upgrade maintains ±10% tolerance matching the original specification. The 630V option provides maximum voltage headroom with active product status and largest inventory.

Parts with ±5% tolerance (C1206C223J2RAC7800, C1206C223JARAC7800) offer improved tolerance performance but are not required for direct substitution. C3216X7R2E223K115AA (TDK, 250V) carries "Not For New Designs" status and should be avoided for new applications despite availability.

All recommended parts are ROHS3 compliant, MSL 1 rated, and maintain the -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can I use a 250V or 630V rated capacitor in place of the 200V B37872K2223K062?

A: Yes. Higher voltage ratings are acceptable substitutes. A 250V or 630V capacitor will function in a 200V application. Voltage rating indicates the maximum voltage the capacitor can withstand; using a higher-rated part provides additional safety margin.

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

A: Tolerance specifies the allowable deviation from the nominal 0.022 µF capacitance value. ±10% allows deviation from 0.0198 µF to 0.0242 µF. ±5% allows deviation from 0.0209 µF to 0.0231 µF. ±5% tolerance parts are more precise but not required for direct substitution of ±10% specifications.

Q: Does thickness variation affect PCB assembly?

A: Thickness variations (0.035" to 0.059") are within the 1206 package specification and do not affect PCB assembly compatibility. All listed parts use the same 1206 (3216 Metric) footprint. Verify PCB clearance if space constraints exist in your design.

Q: Why is the B37872K2223K062 marked obsolete?

A: EPCOS - TDK Electronics has discontinued this part number. Active equivalent parts from KEMET, KYOCERA AVX, TDK, and Samsung Electro-Mechanics provide identical electrical performance with ongoing manufacturing support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and MSL 1 rated, matching the original part's environmental and regulatory status.

Q: Which substitute offers the best availability?

A: C1206C223K2RAC7800 (KEMET) has the highest inventory at 54691 pcs, followed by C3216X7R2J223K130AA (TDK) at 55488 pcs. Both are active products with reliable supply.
