Substitute Part Grouping Explanation

Substitute parts for the B41002A2476M are classified into three categories based on electrical and mechanical compatibility:

Direct Manufacturer Equivalent (6.3TWL47MEFCCR5X7): Maintains identical electrical specifications—47 µF capacitance, 6.3 V voltage rating, ±20% tolerance, and 1000 hours lifetime at 85°C. Physical dimensions and lead spacing are identical. This part is manufactured by Rubycon and carries active product status.

Parametric Equivalent (6.3TWL47MEFC5X7): Matches all electrical parameters of the main part—47 µF, 6.3 V, ±20% tolerance, 1000 hours at 85°C. Physical dimensions and lead spacing are identical. Also manufactured by Rubycon with active product status. Differs only in packaging designation (Bulk vs. standard).

Upgrade Substitutes (16MS747MEFC5X7 and 476PUM016M): These parts increase the voltage rating to 16 V while maintaining 47 µF capacitance and ±20% tolerance. Both are pin-compatible with identical lead spacing and package diameter. These upgrades provide higher voltage margin and improved ripple current handling. The 476PUM016M additionally offers extended lifetime (2000 hours at 85°C) and lower ESR (5.644 Ohm @ 120 Hz).

Engineering Selection Recommendations

For Direct Replacement: Select 6.3TWL47MEFC5X7 or 6.3TWL47MEFCCR5X7 when exact electrical and mechanical specifications must be maintained. Both parts are manufactured by Rubycon with active product status, ensuring long-term availability and supply chain stability. These parts are electrically and physically interchangeable with the B41002A2476M.

For Enhanced Performance: Select 476PUM016M when the circuit design permits a higher voltage rating. This part offers 16 V rating, extended lifetime (2000 hours at 85°C versus 1000 hours), and specified ESR of 5.644 Ohm @ 120 Hz. The part is manufactured by Cornell Dubilier / Illinois Capacitor with active product status. The increased voltage margin provides additional safety margin in applications subject to voltage transients or aging effects.

For Ripple Current Margin: Select 16MS747MEFC5X7 when higher ripple current handling is required. This upgrade provides 73 mA @ 120 Hz and 109.5 mA @ 10 kHz compared to the original 50 mA and 60 mA specifications. The 16 V rating provides additional voltage headroom. Note that this part carries obsolete product status.

Compliance Consideration: All substitute parts maintain ROHS3 compliance, matching the environmental certification of the original B41002A2476M.

Frequently Asked Questions (FAQ)

Q: Can 6.3TWL47MEFC5X7 and 6.3TWL47MEFCCR5X7 be used interchangeably? A: Yes. Both parts are parametric equivalents with identical electrical specifications (47 µF, 6.3 V, ±20% tolerance, 1000 hours @ 85°C) and physical dimensions. The difference is packaging designation only.

Q: What is the advantage of upgrading to 16 V rated parts? A: The 16 V rating provides higher voltage margin and improved ripple current capacity. The 476PUM016M additionally extends lifetime to 2000 hours at 85°C and specifies ESR at 5.644 Ohm @ 120 Hz. These upgrades are suitable when circuit design permits higher voltage ratings.

Q: Is the height difference between B41002A2476M (0.315") and 6.3TWL47MEFCCR5X7 (0.335") significant? A: The 0.020" (0.50 mm) height difference must be evaluated against PCB layout constraints and enclosure clearances. For most applications with standard through-hole spacing, this difference is accommodated within typical design margins. Verify clearance in height-constrained applications.

Q: Which substitute part offers the best long-term availability? A: 6.3TWL47MEFC5X7, 6.3TWL47MEFCCR5X7, and 476PUM016M all carry active product status, indicating current manufacturing and supply chain support. The original B41002A2476M and 16MS747MEFC5X7 are obsolete.
