Substitute Part Grouping Explanation

Substitute parts for the ECQ-UBAF472MA are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires exact matching of the following parameters:

• Capacitance value: 4700 pF
• Tolerance: ±20%
• Voltage Rating - AC: 300V
• Dielectric Material: Polypropylene (PP), Metallized
• Operating Temperature Range: -40°C ~ 110°C
• Mounting Type: Through Hole
• Package / Case: Radial
• Lead Spacing: 0.492" (12.50mm)
• Physical Dimensions: 0.602" L x 0.197" W (15.30mm x 5.00mm)
• Height - Seated (Max): 0.472" (12.00mm)
• Termination: PC Pins
• Safety Ratings: X1, Y2
• RoHS Compliance: ROHS3 Compliant

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No deviations in electrical performance, physical footprint, or regulatory compliance are permitted for substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both ECQ-UBAF472MA and ECQ-UBAF472M are active production parts manufactured by Panasonic Electronic Components within the ECQUB series. Both parts maintain identical electrical specifications, physical dimensions, and regulatory compliance status. Selection between these parts is based on inventory availability and procurement requirements rather than functional differences.

The ECQ-UBAF472M offers higher current inventory availability at 1259 units compared to 971 units for the ECQ-UBAF472MA. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

For applications requiring EMI and RFI suppression with X1, Y2 safety ratings, either part provides equivalent performance in through-hole radial configurations with identical lead spacing and physical footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can ECQ-UBAF472M be used as a direct replacement for ECQ-UBAF472MA?

A: Yes. Both parts are parametric equivalents with identical capacitance (4700 pF), tolerance (±20%), voltage rating (300V AC), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 110°C), physical dimensions, lead spacing, and safety ratings (X1, Y2). No circuit modifications or board layout changes are required.

Q: Are there differences in physical footprint between these parts?

A: No. Both parts share identical dimensions of 0.602" L x 0.197" W (15.30mm x 5.00mm), maximum seated height of 0.472" (12.00mm), and lead spacing of 0.492" (12.50mm). PCB mounting patterns are identical.

Q: What is the difference between ECQ-UBAF472MA and ECQ-UBAF472M?

A: The parts are functionally and mechanically identical. The difference is limited to packaging designation and current inventory levels. ECQ-UBAF472M has higher stock availability (1259 units versus 971 units).

Q: Are both parts RoHS compliant?

A: Yes. Both ECQ-UBAF472MA and ECQ-UBAF472M are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing.

Q: Can these parts be used in safety-critical applications?

A: Both parts carry X1, Y2 safety ratings, indicating suitability for EMI and RFI suppression in applications requiring these classifications. Specific application requirements should be evaluated against the safety rating definitions for your regulatory framework.

Q: What is the tolerance specification for these capacitors?

A: Both parts have a tolerance of ±20%, meaning the actual capacitance value will fall within the range of 3760 pF to 5640 pF at nominal conditions.
