Key Parameters

Substitute Part Grouping Explanation

Substitution of the RFS-100V220MH5#5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 22 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Size / Dimension: 0.394" Dia (10.00mm) (exact match required)
• Height - Seated (Max): 0.787" (20.00mm) (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: Equal to or greater than 100 V
• Lifetime @ Temperature: Equal to or greater than 1000 Hrs @ 85°C
• Operating Temperature Range: Must encompass -40°C ~ 85°C minimum
• Ripple Current: Equal to or greater than specified values

Substitute parts are classified into two categories:

Upgrade Parts: Higher voltage rating and/or extended lifetime specifications, providing enhanced performance margins while maintaining identical physical and electrical compatibility.

Similar Parts: Equivalent voltage and lifetime specifications with identical physical dimensions, suitable for direct replacement in equivalent-performance applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Enhanced Performance:

The EKXG251ELL220MJ20S (Chemi-Con KXG series) is the primary upgrade substitute. This part maintains identical physical dimensions (0.394" diameter, 0.787" height, 5.00mm lead spacing) and electrical specifications (22 µF, ±20% tolerance) while providing:

• Increased voltage rating: 250 V (versus 100 V)
• Extended lifetime: 8000 Hrs @ 105°C (versus 1000 Hrs @ 85°C)
• Expanded operating temperature range: -40°C ~ 105°C
• Active product status, ensuring long-term availability

This part is suitable for all applications where the RFS-100V220MH5#5 was specified, with the added benefit of higher voltage and thermal performance margins.

For Equivalent Performance Replacement:

The UPW2C220MPD (Nichicon UPW series) provides an intermediate upgrade option with:

• Increased voltage rating: 160 V (versus 100 V)
• Extended lifetime: 5000 Hrs @ 105°C (versus 1000 Hrs @ 85°C)
• Identical physical dimensions and lead spacing
• Obsolete product status

For Mechanical Constraint Applications:

The UKW2A220MED (Nichicon UKW series) is classified as a similar part but features different physical dimensions (0.248" diameter, 0.433" height, 2.50mm lead spacing). This part is suitable only for applications where the smaller form factor is required and PCB layout permits the reduced lead spacing. It provides equivalent voltage (100 V) and extended lifetime (2000 Hrs @ 85°C) compared to the main part.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original RFS-100V220MH5#5 specifications.

Frequently Asked Questions (FAQ)

Q: Can EKXG251ELL220MJ20S be used as a direct replacement for RFS-100V220MH5#5?

A: Yes. The EKXG251ELL220MJ20S maintains identical capacitance (22 µF), tolerance (±20%), physical dimensions (0.394" diameter, 0.787" height), and lead spacing (5.00mm). The higher voltage rating (250 V) and extended lifetime (8000 Hrs @ 105°C) provide enhanced performance margins without affecting compatibility.

Q: What is the difference between upgrade and similar substitute parts?

A: Upgrade parts (EKXG251ELL220MJ20S, UPW2C220MPD) maintain identical physical dimensions and lead spacing while providing higher voltage ratings and/or extended lifetime specifications. Similar parts (UKW2A220MED) have equivalent electrical specifications but different physical dimensions and lead spacing, requiring PCB layout verification before substitution.

Q: Is UKW2A220MED compatible with the original PCB design?

A: The UKW2A220MED has different physical dimensions (0.248" diameter, 0.433" height) and lead spacing (2.50mm) compared to the RFS-100V220MH5#5 (0.394" diameter, 0.787" height, 5.00mm lead spacing). PCB layout and through-hole spacing must be verified before substitution. This part is not suitable for direct board-level replacement without PCB modification.

Q: Why is the RFS-100V220MH5#5 marked as obsolete?

A: The RFS-100V220MH5#5 is an obsolete product from Elna America's SILMIC II series. Substitute parts from active manufacturers (Chemi-Con KXG series) are recommended for new designs and long-term availability assurance.

Q: Can a 250 V rated capacitor be used in a 100 V circuit?

A: Yes. Capacitors rated for higher voltages are suitable for lower voltage applications. The EKXG251ELL220MJ20S (250 V rating) operates safely in circuits designed for 100 V operation, providing additional voltage margin and reliability.

Q: What are the ripple current implications for substitution?

A: The EKXG251ELL220MJ20S provides higher ripple current capacity (200 mA @ 120 Hz, 500 mA @ 100 kHz) compared to the RFS-100V220MH5#5 (155 mA @ 120 Hz). This enhanced capability supports applications with higher AC current demands without thermal stress.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (EKXG251ELL220MJ20S, UPW2C220MPD, UKW2A220MED) maintain ROHS3 compliance consistent with the original RFS-100V220MH5#5 specification.
