Key Parameters

Substitute Part Grouping Explanation

Substitution of the B41002A5335M is determined by the following critical parameters:

• Capacitance Value: 3.3 µF (exact match required)
• Tolerance: ±20% (standard tolerance for aluminum electrolytic capacitors)
• Voltage Rating: Minimum 25 V (equal or higher voltage rating acceptable)
• Polarization: Polar (aluminum electrolytic type)
• Physical Dimensions: Lead spacing 0.059" (1.50mm), diameter 0.157" (4.00mm), height 0.315" (8.00mm) maximum
• Mounting Type: Through Hole, Radial configuration
• Package / Case: Radial, Can format
• Operating Temperature Range: -40°C ~ 85°C minimum
• Lifetime Rating: 1000 Hrs @ 85°C minimum

The substitute part 335RSS050M meets all critical substitution criteria. The higher voltage rating (50 V versus 25 V) provides enhanced electrical margin and is a standard substitution practice in capacitor selection.

Parameter Comparison

Engineering Selection Recommendations

The 335RSS050M is a direct substitute for the B41002A5335M based on the following factors:

• Product Status: The substitute part is active and in production, ensuring long-term availability and supply chain continuity.
• Compliance: Both parts are ROHS3 compliant, maintaining regulatory alignment.
• Physical Compatibility: Identical lead spacing, diameter, height, and through-hole radial mounting configuration enable direct PCB footprint compatibility without layout modifications.
• Electrical Compatibility: Matching capacitance value (3.3 µF), tolerance (±20%), operating temperature range (-40°C ~ 85°C), and lifetime rating (1000 Hrs @ 85°C) ensure functional equivalence.
• Voltage Margin: The 50 V rating of the substitute part exceeds the original 25 V specification, providing additional electrical safety margin in the circuit.

Frequently Asked Questions (FAQ)

Q: Can the 335RSS050M be used as a direct replacement for the B41002A5335M?

A: Yes. The substitute part matches all critical electrical and mechanical parameters: capacitance (3.3 µF), tolerance (±20%), operating temperature range (-40°C ~ 85°C), lifetime rating (1000 Hrs @ 85°C), lead spacing (0.059" / 1.50mm), physical dimensions (0.157" diameter, 0.315" height maximum), and through-hole radial mounting configuration. No PCB modifications are required.

Q: Why is the voltage rating of the substitute part higher (50 V vs. 25 V)?

A: Higher voltage-rated capacitors are standard substitutes in engineering practice. The 50 V rating provides additional electrical margin and does not negatively impact circuit performance when the original design operates at 25 V or below. The capacitance value and tolerance remain identical.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant. The substitute part (335RSS050M) is currently in active production status, whereas the original part (B41002A5335M) is obsolete. This ensures continued availability and supply chain support for the substitute.

Q: Will the substitute part fit the existing PCB layout?

A: Yes. The lead spacing (0.059" / 1.50mm), component diameter (0.157" / 4.00mm), and maximum seated height (0.315" / 8.00mm) are identical. The radial, through-hole mounting configuration is unchanged. No PCB redesign is necessary.

Q: What is the difference in ripple current handling?

A: The substitute part (335RSS050M) has higher ripple current ratings: 25 mA @ 120 Hz (versus 15 mA) and 35 mA @ 100 kHz (versus 25.5 mA @ 10 kHz). This represents improved performance capability and does not affect compatibility in applications designed for the original part.
