Substitute Part Grouping Explanation

Substitute parts for the ELHS451VSN101MP25S are identified based on strict electrical and mechanical parameter matching. The substitution logic requires:

Electrical Parameters (Non-negotiable):

• Capacitance value: 100 µF (exact match)
• Rated voltage: 450 V (exact match)
• Tolerance: ±20% or tighter
• Lifetime rating: 5000 hours at 105°C or greater
• Polarization: Polar (same as main part)

Mechanical Parameters (Non-negotiable):

• Lead spacing: 0.394" (10.00 mm)
• Diameter: 0.866" (22.00 mm)
• Mounting type: Through Hole
• Package style: Radial, Can - Snap-In

Compliance Parameters:

• RoHS compliance status (RoHS3 or equivalent acceptable)
• REACH unaffected status

Operating Temperature Consideration: Substitute parts must support the operating temperature range of -40°C to 105°C. A substitute with a narrower lower temperature limit (-25°C minimum instead of -40°C) remains functionally equivalent if the application does not require operation below -25°C.

The identified substitute, 450VXH100MEFCSN22X25 from Rubycon, meets all critical electrical and mechanical parameters while maintaining regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 450VXH100MEFCSN22X25 (Rubycon)

The Rubycon 450VXH100MEFCSN22X25 is a direct electrical and mechanical equivalent to the ELHS451VSN101MP25S. Both components are active products with full regulatory compliance (RoHS3 and REACH unaffected status).

Compatibility Assessment:

All critical electrical parameters match exactly: 100 µF capacitance, 450 V rated voltage, ±20% tolerance, and 5000-hour lifetime at 105°C. Mechanical compatibility is confirmed through identical lead spacing (10.00 mm), diameter (22.00 mm), and snap-in radial can package style.

Operational Considerations:

The substitute component operates across -25°C to 105°C, compared to the main part's -40°C to 105°C range. This difference is significant only if the application requires operation below -25°C. For standard industrial and commercial applications operating within 0°C to 85°C, this parameter difference is not a limiting factor.

The Rubycon substitute features higher ripple current ratings (850 mA @ 120 Hz and 1.19 A @ 10 kHz versus 710 mA and 1.0153 A respectively), providing additional thermal margin in high-ripple-current applications.

Physical height differs by 0.5 mm (27.00 mm versus 27.50 mm), with the substitute being slightly shorter. This minor dimensional difference does not affect PCB layout compatibility for standard through-hole snap-in mounting.

Regulatory Compliance:

Both components meet current regulatory requirements. The main part carries RoHS Compliant status, while the substitute carries ROHS3 Compliant status, representing an equivalent or enhanced compliance level. Both are REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can the Rubycon 450VXH100MEFCSN22X25 be used as a direct replacement for the Chemi-Con ELHS451VSN101MP25S?

A: Yes. Both components share identical electrical specifications (100 µF, 450 V, ±20% tolerance, 5000 Hrs @ 105°C) and mechanical form factors (snap-in radial can, 10.00 mm lead spacing, 22.00 mm diameter). The components are mechanically and electrically interchangeable for standard applications.

Q: What is the significance of the operating temperature range difference (-40°C vs. -25°C)?

A: The main part supports operation down to -40°C, while the substitute supports operation down to -25°C. For applications requiring operation below -25°C, the main part is required. For applications operating within -25°C to 105°C, both parts are equivalent. Most industrial and commercial applications operate within 0°C to 85°C, making this difference non-critical for typical use cases.

Q: Are there any physical mounting differences between these two capacitors?

A: Both capacitors use identical through-hole snap-in mounting with 10.00 mm lead spacing. The substitute is 0.5 mm shorter in seated height (27.00 mm versus 27.50 mm), which does not affect PCB compatibility or mounting clearance for standard designs.

Q: Do both parts meet current regulatory requirements?

A: Yes. The main part is RoHS Compliant and REACH Unaffected. The substitute is ROHS3 Compliant and REACH Unaffected. Both meet current regulatory standards for electronic components.

Q: What does the higher ripple current rating on the substitute mean?

A: The Rubycon substitute has higher ripple current specifications (850 mA @ 120 Hz and 1.19 A @ 10 kHz compared to 710 mA and 1.0153 A). This indicates the substitute can handle higher AC current stress without exceeding temperature limits, providing additional thermal margin in ripple-current-intensive applications.

Q: Can I use the substitute if my design specifies the Chemi-Con part number?

A: Substitution decisions depend on design specifications and procurement policies. From an engineering standpoint, the Rubycon part meets all electrical and mechanical requirements for equivalent performance. Verify with your design authority or procurement department regarding part number substitution procedures.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the RoHS directive. Both compliance levels are acceptable for modern applications.

Q: Are there any performance differences I should consider?

A: Both parts deliver identical capacitance, voltage rating, and lifetime specifications. The substitute offers higher ripple current capability, which is advantageous in high-current applications. The narrower operating temperature range of the substitute is the only functional limitation, relevant only for below -25°C operation.
