Substitute Part Grouping Explanation

Substitution for the 05085C104MAT2W is determined by strict equivalence in the following parameters: capacitance value (0.1 µF), voltage rating (50V), temperature coefficient (X7R), package type (0508/1220 Metric), and mounting method (Surface Mount MLCC). All substitute parts maintain identical physical dimensions (0.050" L x 0.079" W, 1.27mm x 2.00mm) and maximum thickness (0.040"/1.02mm), ensuring mechanical compatibility in PCB layouts.

The substitute parts are grouped into two categories:

Direct Equivalent: KGL21DR71H104MU maintains identical electrical specifications including ±20% tolerance, making it a one-to-one functional replacement.

Upgrade Option: KGL21DR71H104KU provides improved tolerance specification (±10% versus ±20%), offering enhanced precision for applications requiring tighter capacitance control while maintaining all other electrical and mechanical parameters.

All parts share ROHS3 compliance, MSL 1 rating, and identical operating temperature range, confirming full interchangeability within the specified parameter set.

Engineering Selection Recommendations

For Direct Replacement: Select KGL21DR71H104MU when the original 05085C104MAT2W is unavailable. This part provides identical electrical performance and tolerance specification, requiring no circuit design modifications. Both parts are active products with full ROHS3 compliance and MSL 1 rating.

For Specification Enhancement: Select KGL21DR71H104KU when circuit requirements demand improved capacitance accuracy. The ±10% tolerance provides tighter control compared to the ±20% specification of the original part, while maintaining all other electrical and mechanical characteristics. This upgrade is suitable for precision bypass and decoupling applications where capacitance drift must be minimized across the operating temperature range.

All three parts are manufactured by KYOCERA AVX and carry identical compliance certifications (ROHS3, REACH Unaffected, EAR99), confirming suitability for regulated and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can KGL21DR71H104MU be used as a direct replacement for 05085C104MAT2W?

A: Yes. Both parts are electrically and mechanically identical, with matching capacitance (0.1 µF), voltage rating (50V), tolerance (±20%), temperature coefficient (X7R), and package dimensions (0508/1220 Metric). No circuit modifications are required.

Q: What is the difference between KGL21DR71H104MU and KGL21DR71H104KU?

A: The primary difference is tolerance specification. KGL21DR71H104MU maintains ±20% tolerance matching the original part, while KGL21DR71H104KU provides improved ±10% tolerance. All other parameters, including capacitance, voltage rating, package type, and operating temperature range, are identical.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All three parts share identical physical dimensions (0.050" L x 0.079" W) and maximum thickness (0.040"), ensuring mechanical compatibility with existing PCB designs without layout modifications.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 rating. They are suitable for identical applications and manufacturing environments.

Q: When should KGL21DR71H104KU be selected over the other options?

A: Select KGL21DR71H104KU when circuit specifications require tighter capacitance tolerance control. The ±10% tolerance is beneficial for precision decoupling and bypass applications where capacitance variation across temperature and voltage conditions must be minimized.
