Substitute Part Grouping Explanation

Substitution of the B41570A9339Q000 is determined by the following critical parameters:

• Capacitance Value: 33000 µF (exact match required)
• Voltage Rating: 100 V (exact match required)
• Package Configuration: Radial, Can - Screw Terminals (exact match required)
• Physical Dimensions: 3.028" Dia × 5.677" Height with 1.248" lead spacing (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Polarization: Polar (exact match required)

The B41560A9339M000 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. While secondary parameters such as ESR, ripple current rating, and lifetime specifications differ, the substitute maintains functional equivalence for applications where the primary requirement is 33000 µF capacitance at 100 V with screw terminal connectivity.

Parameter Comparison

Engineering Selection Recommendations

The B41560A9339M000 is the manufacturer-recommended substitute for the obsolete B41570A9339Q000. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production continuity.

The substitute part is currently in active production status, providing supply chain stability compared to the obsolete main part. Physical and electrical compatibility is confirmed through identical package configuration, dimensions, and screw terminal connectivity.

Selection of the B41560A9339M000 is appropriate for applications requiring 33000 µF capacitance at 100 V with chassis-mount screw terminal configuration. The lower ESR (5 mOhm vs. 9 mOhm) of the substitute represents an improvement in performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the B41560A9339M000 be used as a direct replacement for the B41570A9339Q000?

A: Yes. Both parts share identical capacitance (33000 µF), voltage rating (100 V), package configuration (Radial, Can - Screw Terminals), physical dimensions (3.028" Dia × 5.677" Height), and lead spacing (1.248"). Mechanical and electrical compatibility is confirmed.

Q: What are the differences between these two parts?

A: The substitute part features lower ESR (5 mOhm vs. 9 mOhm), tighter capacitance tolerance (±20% vs. -10%, +30%), and a defined operating temperature range (-40°C ~ 105°C). The main part specifies 20000 hours lifetime at 105°C, while the substitute specifies 3000 hours. Ripple current rating is slightly lower in the substitute (21 A vs. 23 A @ 100 Hz).

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status.

Q: Why is the main part listed as obsolete?

A: The B41570A9339Q000 has been discontinued by the manufacturer. The B41560A9339M000 is the active production equivalent and is recommended for all new applications and ongoing supply requirements.

Q: Will the substitute part fit in the same PCB layout or chassis mounting location?

A: Yes. Identical physical dimensions and lead spacing ensure direct mechanical compatibility with existing mounting locations and circuit board layouts designed for the B41570A9339Q000.
