Substitute Part Grouping Explanation

The 25MU154KZ22012 qualifies as a parametric equivalent substitute for the 16MU154KZ22012 based on the following criteria:

Matching Parameters:

• Capacitance: 0.15 µF (identical)
• Tolerance: ±10% (identical)
• Dielectric Material: Acrylic, Metallized (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Package / Case: 0805 (2012 Metric) (identical)
• Physical Dimensions: 0.079" L x 0.049" W, 0.047" Height (identical)
• Mounting Type: Surface Mount (identical)
• Termination: Solder Pads (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 3 (168 Hours) (identical)

Differing Parameter:

• Voltage Rating - DC: 25V (substitute) vs. 16V (main part)

The substitute part operates at a higher voltage rating, making it suitable for applications where the original 16V rating is insufficient or where design margin improvement is required.

Parameter Comparison

Engineering Selection Recommendations

Both the 16MU154KZ22012 and 25MU154KZ22012 are active products with ROHS3 compliance and identical physical and thermal characteristics. The 25MU154KZ22012 provides higher voltage headroom at 25V DC compared to the 16V DC rating of the primary part. Selection between these parts depends on circuit voltage requirements. The 25MU154KZ22012 offers greater availability with 4000 units in stock compared to 768 units of the primary part.

Frequently Asked Questions (FAQ)

Q: Can the 25MU154KZ22012 be used as a direct replacement for the 16MU154KZ22012?

A: Yes, the 25MU154KZ22012 is a direct substitute in terms of physical footprint, capacitance value, tolerance, and thermal operating range. The higher voltage rating (25V vs. 16V) makes it suitable for the same 16V application with increased design margin.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use identical 0805 (2012 Metric) surface mount packages with the same physical dimensions (0.079" L x 0.049" W) and maximum seated height (0.047"). They are pin-compatible and require no PCB layout modifications.

Q: What is the significance of the voltage rating difference?

A: The 25MU154KZ22012 operates at a higher maximum DC voltage (25V) compared to the 16MU154KZ22012 (16V). In applications operating at or below 16V DC, the substitute part provides additional voltage safety margin. The capacitance and tolerance remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the 16MU154KZ22012 and 25MU154KZ22012 are ROHS3 compliant and have identical moisture sensitivity levels (MSL 3, 168 Hours).

Q: Which part should be selected for new designs?

A: Selection is based on circuit voltage requirements. For circuits operating at 16V DC or below, either part is suitable. The 25MU154KZ22012 is recommended when higher voltage margin is desired or when inventory availability is a consideration, as it has greater stock availability (4000 units vs. 768 units).
