Key Parameters

Substitute Part Grouping Explanation

The substitute part 150473K250BB qualifies as an equivalent component based on the following matching criteria:

Identical Parameters:

• Capacitance: 0.047 µF
• Voltage Rating - DC: 250V
• Dielectric Material: Polyester, Metallized
• Tolerance: ±10%
• Operating Temperature Range: -55°C to 125°C
• Mounting Type: Through Hole
• Package Type: Axial
• Termination: PC Pins
• RoHS Status: ROHS3 Compliant

Variant Parameters (Within Acceptable Tolerance):

• Voltage Rating - AC: 125V (MMWA2S47K-F) vs. 160V (150473K250BB)
• Physical Dimensions: 0.217" Dia x 0.563" L vs. 0.236" Dia x 0.650" L

The substitute maintains full electrical compatibility through matching DC voltage ratings and capacitance specifications. Physical dimension differences require verification for board layout and mechanical clearance in the target application.

Parameter Comparison

Engineering Selection Recommendations

Both MMWA2S47K-F and 150473K250BB are Active status products fully compliant with ROHS3 and REACH regulations. The primary distinction between these components is physical package size. The 150473K250BB is approximately 15% larger in diameter and 16% longer than the MMWA2S47K-F. Board-level integration requires dimensional verification against available footprint space. The higher AC voltage rating of the 150473K250BB (160V vs. 125V) provides increased operational margin in AC applications without affecting DC circuit compatibility. Both components are suitable for general-purpose capacitive applications.

Frequently Asked Questions (FAQ)

Q: Can 150473K250BB replace MMWA2S47K-F in my circuit? A: Yes, both parts share identical capacitance (0.047 µF) and DC voltage rating (250V). Physical dimensions must be verified for board-level compatibility.

Q: What is the key difference between these two parts? A: The primary difference is package size. The 150473K250BB measures 0.236" Dia x 0.650" L compared to 0.217" Dia x 0.563" L for the MMWA2S47K-F. The substitute also features a higher AC voltage rating (160V vs. 125V).

Q: Are both parts RoHS compliant? A: Yes, both MMWA2S47K-F and 150473K250BB are ROHS3 compliant and REACH unaffected.
