EET-HC2W151BA Equivalent & Substitute Parts

Part Overview

The EET-HC2W151BA is a 150 µF, 450 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the TS-HC series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring high voltage energy storage and filtering. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical equivalence across capacitance, voltage rating, tolerance, and mechanical compatibility while meeting current manufacturing and compliance standards.

Substitute Part Grouping Explanation

Substitution eligibility for the EET-HC2W151BA is determined by strict equivalence across the following parameters:

Capacitance: 150 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Package / Case: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Size / Dimension: 0.866" Dia (22.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

All substitute parts listed below meet these core electrical and mechanical requirements. Secondary parameters such as ESR, ripple current ratings, and lifetime specifications may vary within acceptable ranges for general-purpose applications. Operating temperature range and compliance certifications are provided for design consideration.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the EET-HC2W151BA across the core parameters required for direct replacement: 150 µF capacitance, 450 V voltage rating, ±20% tolerance, 10.00 mm lead spacing, 22.00 mm diameter, and radial snap-in package configuration.

The Rubycon 450MXG150MEFCSN22X35 offers active product status with a reduced seated height of 37.00 mm compared to the original 42.00 mm specification. This dimensional difference may require PCB layout verification for applications with height constraints.

The EPCOS - TDK Electronics B43508 series variants (B43508A5157M000, M2, M60, M62, M67, M7, M80, M82, M87) are all active products with extended operating temperature range (-40°C to 105°C versus -25°C to 105°C for the original). These parts are ROHS3 compliant and REACH unaffected, providing compliance advantages for new designs. Minor height variations exist within the B43508 series (42.00 mm to 42.20 mm), which fall within standard manufacturing tolerances for snap-in can capacitors.

Selection should prioritize active product status for long-term supply assurance and compliance with current environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the Rubycon 450MXG150MEFCSN22X35 be used as a direct replacement despite its reduced height?

A: The Rubycon part meets all electrical and core mechanical specifications. The 5 mm height reduction (37.00 mm versus 42.00 mm) is within acceptable substitution parameters for general-purpose applications. PCB layout and clearance verification is required for applications with tight vertical spacing constraints.

Q: What is the difference between the multiple EPCOS B43508 part numbers?

A: All B43508 variants listed (M000, M2, M60, M62, M67, M7, M80, M82, M87) share identical electrical specifications: 150 µF, 450 V, ±20% tolerance, and equivalent mechanical dimensions. The suffix designations represent manufacturing date codes or internal EPCOS tracking identifiers. Height specifications vary slightly (42.00 mm or 42.20 mm), which is within standard manufacturing tolerance for radial can capacitors.

Q: Are all substitute parts RoHS and REACH compliant?

A: The Rubycon 450MXG150MEFCSN22X35 is ROHS3 compliant and REACH unaffected. All EPCOS - TDK Electronics B43508 variants are ROHS3 compliant and REACH unaffected. The original Panasonic EET-HC2W151BA is REACH affected. For new designs requiring full compliance, EPCOS or Rubycon substitutes are recommended.

Q: Can these parts be used in applications requiring extended low-temperature operation?

A: The EPCOS - TDK Electronics B43508 series supports -40°C minimum operating temperature, compared to -25°C for the original Panasonic part and Rubycon substitute. For applications requiring operation below -25°C, EPCOS variants are the appropriate selection.

Q: Is the lead spacing identical across all substitute parts?

A: Yes. All substitute parts maintain 0.394" (10.00 mm) lead spacing and 0.866" (22.00 mm) diameter, ensuring direct PCB footprint compatibility with the original EET-HC2W151BA.
