Engineering Selection Recommendations

Primary Substitute - Rubycon 450MXG150MEFCSN30X25: This component is the closest functional equivalent to the EET-HC2W151DA. It maintains identical electrical specifications (150 µF, 450 V, ±20% tolerance) and mechanical dimensions (30 mm diameter, 27 mm height, 10 mm lead spacing). The MXG series offers improved lifetime (3000 Hrs @ 105°C versus 2000 Hrs), and the part is in active production status with ROHS3 compliance. This is the preferred choice for direct replacement in existing designs.

Secondary Substitutes - EPCOS B43508 Series: The B43508 family (B43508C5157M, B43508C5157M2, B43508C5157M60, B43508C5157M62, B43508C5157M67, B43508C5157M7, B43508C5157M80, B43508C5157M82, B43508C5157M87) provides full electrical and mechanical compatibility. All variants maintain 150 µF capacitance at 450 V with ±20% tolerance and identical lead spacing. These parts feature extended operating temperature range (-40°C ~ 105°C versus -25°C ~ 105°C) and 3000 Hrs lifetime at 105°C. Minor height variations exist (27.00 mm or 27.20 mm maximum seated height), which remain within acceptable PCB clearance tolerances. All B43508 variants are active products with ROHS3 compliance.

Selection Criteria:

For new designs: Select Rubycon 450MXG150MEFCSN30X25 or any B43508 variant based on availability and lead time.
For retrofit applications: Verify PCB clearance for B43508 variants with 27.20 mm height (B43508C5157M80, B43508C5157M82, B43508C5157M87).
All substitutes are electrically interchangeable within the specified tolerance and operating conditions.

Frequently Asked Questions (FAQ)

Q: Can I use any B43508 variant as a direct replacement for the EET-HC2W151DA? A: Yes. All B43508 variants listed (B43508C5157M, B43508C5157M2, B43508C5157M60, B43508C5157M62, B43508C5157M67, B43508C5157M7, B43508C5157M80, B43508C5157M82, B43508C5157M87) meet the mandatory electrical and mechanical parameters. The suffix designations indicate manufacturing date codes and do not affect electrical performance or physical compatibility.

Q: What is the difference between the Rubycon and EPCOS substitutes? A: Both manufacturers provide 150 µF, 450 V aluminum electrolytic capacitors in identical snap-in packages with 10 mm lead spacing and 30 mm diameter. The Rubycon MXG series maintains the original operating temperature range (-25°C ~ 105°C), while EPCOS B43508 variants extend the lower temperature limit to -40°C. Both offer 3000 Hrs lifetime at 105°C, exceeding the original 2000 Hrs specification.

Q: Are there height differences I need to consider? A: The Rubycon 450MXG150MEFCSN30X25 and most B43508 variants (B43508C5157M through B43508C5157M7) have a maximum seated height of 27.00 mm, matching the original EET-HC2W151DA. Three B43508 variants (B43508C5157M80, B43508C5157M82, B43508C5157M87) have a maximum seated height of 27.20 mm. Verify PCB clearance if space is constrained; the 0.20 mm difference is typically negligible in standard designs.

Q: Do all substitutes have the same lead spacing? A: Yes. All substitute parts maintain 0.394" (10.00 mm) lead spacing, ensuring direct PCB footprint compatibility without layout modifications.

Q: Are these parts RoHS compliant? A: The Rubycon 450MXG150MEFCSN30X25 and all EPCOS B43508 variants are ROHS3 compliant. The original EET-HC2W151DA is not listed with RoHS status, making these substitutes suitable for applications requiring RoHS compliance.

Q: Can I mix different substitute manufacturers in the same design? A: Yes. All listed substitutes are electrically and mechanically equivalent. Mixing Rubycon and EPCOS components in the same circuit is acceptable from an engineering standpoint, though procurement and quality control practices may favor single-source selection.
