Parameter Comparison

Engineering Selection Recommendations

The CGA2B2X7R1H682M050BA from TDK Corporation is a direct equivalent to the MLASU105SB7682MFNA01. Both parts are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Selection Basis:

The TDK substitute part matches all critical electrical specifications: 6800 pF capacitance, 50V voltage rating, ±20% tolerance, and X7R temperature coefficient across the -55°C to 125°C operating range. Physical dimensions and mounting characteristics are identical, ensuring PCB layout compatibility without design modification.

The TDK part carries AEC-Q200 automotive qualification, which represents an enhanced reliability rating beyond the original part's medical/non-critical application designation. This additional qualification does not create incompatibility and provides equivalent or superior performance characteristics for the specified electrical and thermal parameters.

Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification, eliminating special handling requirement differences. Packaging format (Tape & Reel) and surface mount assembly process compatibility are identical.

Frequently Asked Questions (FAQ)

Q: Can the CGA2B2X7R1H682M050BA be used as a direct replacement for MLASU105SB7682MFNA01 without PCB redesign?

A: Yes. Both parts share identical physical dimensions (0.039" L x 0.020" W, 0.022" max thickness), package type (0402/1005 Metric), and mounting method (surface mount MLCC). No PCB layout modifications are required.

Q: Are the electrical characteristics identical between these two parts?

A: Yes. Both parts specify 6800 pF capacitance, ±20% tolerance, 50V voltage rating, X7R temperature coefficient, and -55°C to 125°C operating temperature range. Electrical performance is equivalent.

Q: What is the difference between the original Taiyo Yuden part and the TDK substitute?

A: The primary difference is manufacturer and application designation. The TDK part carries AEC-Q200 automotive qualification, while the Taiyo Yuden part is designated for medical and non-critical applications. Both meet identical electrical and mechanical specifications for this capacitor value and package.

Q: Does the AEC-Q200 rating on the TDK part affect compatibility?

A: No. AEC-Q200 is an automotive reliability qualification that represents enhanced testing and quality standards. It does not create incompatibility with the original design specification and provides equivalent or superior performance for the electrical parameters required.

Q: Are moisture sensitivity requirements the same for both parts?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no special moisture sensitivity handling requirements. Storage and handling procedures are identical.

Q: Can inventory be mixed between these two part numbers?

A: Yes, from an electrical and mechanical compatibility standpoint. However, inventory management practices should follow your organization's procedures for part number tracking and traceability.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements identically.
