Key Parameters

Substitute Part Grouping Explanation

Substitution of the RFS-100V100MH4#5 is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value must equal 10 µF
• Tolerance must be ±20% or tighter
• Voltage rating must be equal to or greater than 100 V
• Polarization must remain Polar

Mechanical Compatibility:

• Lead spacing must equal 0.197" (5.00mm)
• Package type must be Radial, Can
• Mounting type must be Through Hole
• Physical dimensions must accommodate the 0.394" diameter and 0.630" maximum height

Compliance Requirements:

• RoHS3 compliance required
• REACH Unaffected status required

Substitute parts are categorized as follows:

Upgrade Substitutes (Enhanced Performance):

• EKXG201ELL100MJ16S (Chemi-Con KXG series)
• UPS2D100MPD (Nichicon UPS series)
• UPW2D100MPD (Nichicon UPW series)

These parts maintain identical capacitance, tolerance, lead spacing, and physical dimensions while offering higher voltage ratings (200 V) and extended lifetime ratings at elevated temperatures.

Similar Substitute (Equivalent Voltage):

• UKW2A100MED (Nichicon UKW series)

This part maintains the 100 V voltage rating and audio application focus but differs in physical dimensions and lead spacing, requiring mechanical compatibility verification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Mechanical and Electrical Replacement:

EKXG201ELL100MJ16S, UPS2D100MPD, and UPW2D100MPD are suitable direct replacements. All three maintain identical lead spacing (0.197"/5.00mm), physical dimensions (0.394" diameter, 0.630" height), and mounting configuration. These parts satisfy all mechanical compatibility requirements for through-hole PCB assembly without modification.

EKXG201ELL100MJ16S is the preferred upgrade substitute due to its Active product status and superior lifetime rating of 8000 hours at 105°C, compared to the original 1000 hours at 85°C. This part is currently in stock with 7790 units available.

UPS2D100MPD and UPW2D100MPD are functionally equivalent alternatives with 2000 and 5000 hour lifetime ratings respectively at 105°C. Both are obsolete but currently available in inventory.

For Equivalent Voltage Rating:

UKW2A100MED maintains the original 100 V voltage rating and audio application designation. However, this part has different physical dimensions (0.248" diameter, 0.433" height) and reduced lead spacing (0.098"/2.50mm), requiring PCB layout modification and mechanical compatibility verification before implementation.

Compliance Considerations:

All substitute parts meet RoHS3 compliance and REACH Unaffected requirements, matching the original component's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can EKXG201ELL100MJ16S be used as a direct replacement for RFS-100V100MH4#5?

A: Yes. EKXG201ELL100MJ16S maintains identical capacitance (10 µF), tolerance (±20%), lead spacing (0.197"/5.00mm), and physical dimensions (0.394" diameter, 0.630" height). The 200 V rating provides additional voltage margin over the original 100 V specification. All mounting and compliance parameters are compatible.

Q: What is the difference between the upgrade substitutes?

A: EKXG201ELL100MJ16S, UPS2D100MPD, and UPW2D100MPD differ in manufacturer, series designation, and lifetime ratings. EKXG201ELL100MJ16S (Chemi-Con KXG) offers 8000 hours at 105°C and Active product status. UPS2D100MPD (Nichicon UPS) provides 2000 hours at 105°C. UPW2D100MPD (Nichicon UPW) provides 5000 hours at 105°C. All three are mechanically and electrically interchangeable.

Q: Why does UKW2A100MED have different dimensions?

A: UKW2A100MED is from the Nichicon UKW series, which uses a different physical form factor. The 0.248" diameter and 0.433" height, combined with 0.098" lead spacing, indicate a smaller package design. This part is suitable only if PCB layout can accommodate the reduced dimensions and modified lead spacing.

Q: Are all substitute parts currently available?

A: EKXG201ELL100MJ16S is Active with 7790 units in stock. UPS2D100MPD has 2793 units available. UPW2D100MPD has 2782 units available. UKW2A100MED has 4224 units available. All parts are listed as New Original In Stock.

Q: What compliance certifications do the substitute parts carry?

A: All substitute parts are ROHS3 Compliant and REACH Unaffected, matching the original RFS-100V100MH4#5 regulatory status.

Q: Can I use a 200 V rated capacitor in a circuit designed for 100 V?

A: Yes. A higher voltage rating provides additional safety margin and does not affect circuit operation. The 200 V rated substitutes (EKXG201ELL100MJ16S, UPS2D100MPD, UPW2D100MPD) are suitable for circuits rated at 100 V or lower.
