Key Parameters

Substitute Part Grouping Explanation

Substitution of the B41002A6335M is determined by strict equivalence across the following parameters:

• Capacitance Value: 3.3 µF (exact match required)
• Voltage Rating: 50 V (minimum acceptable rating)
• Tolerance: ±20% (electrical tolerance specification)
• Polarization: Polar (electrolytic type requirement)
• Mechanical Compatibility: Lead spacing 0.059" (1.50mm), diameter 0.157" (4.00mm), height 0.315" (8.00mm) maximum
• Mounting Type: Through Hole radial configuration
• Thermal Rating: 1000 Hrs @ 85°C minimum lifetime specification
• Operating Temperature: -40°C ~ 85°C range
• Compliance: ROHS3 Compliant

The substitute part 335RSS050M from Cornell Dubilier / Illinois Capacitor meets all these criteria and is classified as an active product, providing continuity for applications previously using the obsolete B41002A6335M.

Parameter Comparison

Engineering Selection Recommendations

The 335RSS050M is a direct parametric equivalent to the B41002A6335M. Both components share identical electrical specifications (3.3 µF, 50 V, ±20% tolerance), thermal ratings (1000 Hrs @ 85°C), and mechanical dimensions (0.157" diameter, 0.315" height, 0.059" lead spacing). Both are ROHS3 compliant and rated for the same operating temperature range (-40°C ~ 85°C).

The primary distinction is product status: the B41002A6335M is obsolete, while the 335RSS050M is active. The substitute part is manufactured by Cornell Dubilier / Illinois Capacitor, an established supplier of aluminum electrolytic capacitors. Selection of the 335RSS050M ensures continued component availability and supply chain continuity for applications requiring this capacitance and voltage specification.

Frequently Asked Questions (FAQ)

Q: Can the 335RSS050M be used as a direct replacement for the B41002A6335M?

A: Yes. Both components have identical capacitance (3.3 µF), voltage rating (50 V), tolerance (±20%), thermal lifetime (1000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), and mechanical dimensions (0.157" diameter, 0.315" height, 0.059" lead spacing). The radial, can package and through-hole mounting are identical, allowing direct PCB substitution.

Q: Why is the B41002A6335M listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The B41002A6335M is no longer in active production by EPCOS - TDK Electronics. The 335RSS050M provides equivalent functionality and is currently in active production.

Q: Are there any differences in ESR or ripple current specifications?

A: The B41002A6335M does not specify ESR in the provided data. The 335RSS050M specifies 50.238 Ohm ESR @ 120 Hz. Ripple current specifications differ slightly: B41002A6335M is rated 22 mA @ 120 Hz and 41.8 mA @ 10 kHz, while 335RSS050M is rated 25 mA @ 120 Hz and 35 mA @ 100 kHz. These differences do not affect substitution eligibility for general purpose applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the B41002A6335M and 335RSS050M are ROHS3 compliant.

Q: What is the lead spacing and can this part fit existing PCB layouts?

A: Both components have identical lead spacing of 0.059" (1.50mm) and identical physical dimensions (0.157" diameter, 0.315" maximum height). The 335RSS050M will fit existing PCB layouts designed for the B41002A6335M without modification.
