Substitute Part Grouping Explanation

Substitution for the B37650C0106M062 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Capacitance: 10 µF (exact match required)
Voltage Rating: 25V (exact match required)
Temperature Coefficient: X5R (exact match required)
Package / Case: 1210 (3225 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Operating Temperature Range: -55°C to 85°C (exact match required)

Secondary Compatibility Parameters:

Tolerance: ±20% (primary specification; ±10% represents improved tolerance and is acceptable as upgrade)
RoHS Status: ROHS3 Compliant (all substitutes maintain compliance)
Moisture Sensitivity Level: 1 (Unlimited) (all substitutes maintain MSL-1 rating)

Direct substitutes maintain identical electrical and mechanical specifications. Upgrade options provide tighter tolerance (±10%) or higher voltage rating (35V) while preserving all other critical parameters.

Engineering Selection Recommendations

Direct Substitutes (Identical Specifications):

For applications requiring exact electrical and mechanical equivalence to B37650C0106M062, the following active production parts are recommended:

C1210C106M3PAC7800 (KEMET): Active product status with standard packaging options. Thickness reduced to 2.10mm provides improved PCB layout flexibility.
CL32A106MAILNNE (Samsung Electro-Mechanics): Active product status. Thickness of 2.20mm maintains compatibility with standard PCB assembly processes.
KGM32JR51E106MU (KYOCERA AVX): Active product status with established supply chain availability.

Upgrade Options:

C1210C106K3PAC7800 (KEMET): Tighter tolerance specification (±10% vs ±20%) with active product status. Suitable for applications requiring improved capacitance accuracy.
C1210C106M6PAC7800 (KEMET): Higher voltage rating (35V vs 25V) with active product status. Applicable for designs requiring increased voltage margin or future specification changes.

Legacy Alternatives (Not For New Designs):

The following parts maintain full electrical and mechanical compatibility but carry "Not For New Designs" status:

C3225X5R1E106M250AA (TDK Corporation)
GRM32DR61E106MA12L (Murata Electronics)
TMK325BJ106MD-T (Taiyo Yuden)
TMK325BJ106MN-T (Taiyo Yuden)

These parts are suitable for replacement in existing production runs or maintenance applications but should not be selected for new product designs.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with ±10% tolerance instead of ±20%?

A: Yes. Tighter tolerance specifications (±10%) are electrically compatible and represent an upgrade path. The part C1210C106K3PAC7800 provides this improved tolerance while maintaining all other critical parameters.

Q: What is the difference between direct substitutes and upgrade options?

A: Direct substitutes maintain identical capacitance, voltage, tolerance, and temperature coefficient specifications. Upgrade options modify one parameter (tolerance or voltage rating) while preserving all other critical electrical and mechanical characteristics. Selection depends on application requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL-1 (Unlimited) moisture sensitivity rating, matching the original B37650C0106M062 specification.

Q: Does package thickness variation affect PCB assembly compatibility?

A: Package thickness varies from 0.95mm to 2.80mm across substitute options. All parts maintain the 1210 (3225 Metric) footprint and surface mount MLCC mounting type. Verify PCB assembly equipment clearance specifications for parts with thickness below 2.10mm or above 2.70mm.

Q: Can I use a 35V rated part in a 25V application?

A: Yes. The C1210C106M6PAC7800 (35V rating) is electrically compatible with 25V applications. Higher voltage ratings provide increased safety margin and are suitable for designs requiring future specification flexibility.

Q: Why is the original B37650C0106M062 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Active substitute parts from KEMET, Samsung Electro-Mechanics, and KYOCERA AVX provide equivalent functionality with ongoing supply availability.

Q: Which substitute offers the best long-term supply availability?

A: Parts with "Active" product status provide the most reliable long-term supply: C1210C106M3PAC7800 (KEMET), CL32A106MAILNNE (Samsung Electro-Mechanics), KGM32JR51E106MU (KYOCERA AVX), C1210C106K3PAC7800 (KEMET), and C1210C106M6PAC7800 (KEMET).
