Substitute Part Grouping Explanation

Substitution eligibility for the EKXG201EC3101ML20S is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Capacitance value (100 µF), rated voltage (200 V), and tolerance (±20%) must match exactly. Lifetime rating (10,000 hours at 105°C) and operating temperature range (-40°C to 105°C) establish reliability equivalence.

Mechanical Compatibility: Lead spacing (0.295" / 7.50 mm), can diameter (0.630" / 16.00 mm), and maximum seated height (0.846" / 21.50 mm) must be identical to ensure PCB footprint compatibility without layout modification.

Functional Characteristics: Ripple current performance at both low frequency (120 Hz) and high frequency (100 kHz) must support the intended application load. Polarization (Polar) and mounting type (Through Hole, Radial) are non-negotiable.

Compliance & Status: Active product status, RoHS3 compliance, and REACH unaffected designation ensure regulatory alignment and supply chain continuity.

The UCS2D101MHD1TN from Nichicon meets all substitution criteria and is classified as a parametric equivalent.

Engineering Selection Recommendations

The UCS2D101MHD1TN (Nichicon) is a direct parametric equivalent to the EKXG201EC3101ML20S (Chemi-Con) for applications requiring 100 µF, 200 V aluminum electrolytic capacitors with through-hole radial mounting. Both components maintain Active product status and full RoHS3 compliance with REACH unaffected designation, ensuring regulatory continuity and supply chain reliability.

Electrical and mechanical specifications are identical across all critical parameters: capacitance, voltage rating, tolerance, lifetime rating, operating temperature range, lead spacing, can diameter, and seated height. Ripple current performance at both 120 Hz and 100 kHz is equivalent within normal manufacturing variation, supporting identical application loads.

Selection between these two parts may be based on inventory availability, packaging format (Tape & Reel versus Cut Tape), or established supplier relationships, as both components satisfy all functional and compliance requirements for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the UCS2D101MHD1TN replace the EKXG201EC3101ML20S without PCB modification?

A: Yes. Both components share identical mechanical dimensions (0.630" diameter, 0.846" maximum height, 0.295" lead spacing) and mounting type (through-hole radial). Direct PCB footprint compatibility is confirmed.

Q: Are the electrical specifications truly equivalent?

A: Yes. Capacitance (100 µF), voltage rating (200 V), tolerance (±20%), lifetime (10,000 hours at 105°C), and operating temperature range (-40°C to 105°C) are identical. Ripple current performance at 120 Hz and 100 kHz is equivalent within normal manufacturing tolerances.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape wound on a reel, suitable for automated assembly equipment. Cut Tape packaging is supplied as individual segments cut from the carrier tape, suitable for manual assembly or smaller production runs. Both formats contain the same component; packaging selection depends on assembly process requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the EKXG201EC3101ML20S and UCS2D101MHD1TN are RoHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Q: Which part should be selected if both are available?

A: Selection may be based on inventory availability, packaging format preference, lead time, or established supplier relationships. From an engineering standpoint, both components are functionally and mechanically equivalent and will perform identically in the circuit.
