Substitute Part Grouping Explanation

Substitution of the EMKB401ADA2R2MHA0G is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance value: 2.2 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 400 V minimum (equal or higher acceptable)
• Polarization: Polar (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Case size: 0.315" Dia (8.00 mm) (exact match required)
• Surface mount land size: 0.327" L x 0.327" W (8.30 mm x 8.30 mm) (exact match required)
• Mounting type: Surface Mount (exact match required)

Secondary Compatibility Parameters:

• Operating temperature range: -40°C minimum to 105°C minimum
• Ripple current ratings at specified frequencies
• Lifetime rating at temperature
• RoHS and REACH compliance status

Two substitute parts meet these criteria and are classified as follows:

Parametric Equivalent: UUX2G2R2MNL1GS (Nichicon UUX series) - Matches all primary electrical and mechanical specifications with identical voltage rating and case dimensions.

Upgrade Substitute: ULH2W2R2MNL1GS (Nichicon ULH series) - Exceeds voltage rating (450 V vs. 400 V) and operating temperature range (-40°C to 125°C vs. -40°C to 105°C), with improved lifetime rating (4000 Hrs @ 125°C vs. 3000 Hrs @ 105°C), while maintaining identical case size and land pattern.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent):

The UUX2G2R2MNL1GS from Nichicon is the parametric equivalent substitute. This part maintains identical electrical specifications (2.2 µF, 400 V, ±20% tolerance) and mechanical dimensions (8.00 mm diameter, 10.50 mm height, 8.30 mm x 8.30 mm land pattern). The UUX series is active in production with ROHS3 compliance and unlimited moisture sensitivity rating. This substitute is suitable for direct board-level replacement without design modification. Inventory availability is significantly higher (27801 pcs) compared to the obsolete EMKB401ADA2R2MHA0G.

For Enhanced Performance (Upgrade Substitute):

The ULH2W2R2MNL1GS from Nichicon provides an upgrade path with higher voltage rating (450 V vs. 400 V) and extended operating temperature range (-40°C to 125°C vs. -40°C to 105°C). The lifetime rating is improved to 4000 hours at 125°C. The case diameter and land pattern remain identical; however, the seated height increases from 10.50 mm to 11.00 mm. This substitute is suitable for applications where thermal margin and voltage headroom are beneficial. ROHS3 compliance and unlimited moisture sensitivity rating are maintained. Inventory availability is adequate (5079 pcs).

Compliance Considerations:

Both substitute parts maintain RoHS and REACH compliance status equivalent to or exceeding the original part. Both are classified as ECCN EAR99 and HTSUS 8532.22.0020, consistent with the original component.

Frequently Asked Questions (FAQ)

Q1: Can UUX2G2R2MNL1GS be used as a direct drop-in replacement for EMKB401ADA2R2MHA0G?

A: Yes. The UUX2G2R2MNL1GS is a parametric equivalent with identical capacitance (2.2 µF), voltage rating (400 V), tolerance (±20%), case size (8.00 mm diameter), height (10.50 mm), and land pattern (8.30 mm x 8.30 mm). No design modification is required for board-level substitution.

Q2: What is the difference between the two substitute parts?

A: The UUX2G2R2MNL1GS matches the original specifications exactly. The ULH2W2R2MNL1GS offers higher voltage rating (450 V), extended temperature range (-40°C to 125°C), and improved lifetime (4000 Hrs @ 125°C), but has a slightly taller profile (11.00 mm vs. 10.50 mm). Selection depends on application thermal and voltage requirements.

Q3: Are there height clearance concerns with the ULH2W2R2MNL1GS?

A: The ULH2W2R2MNL1GS has a maximum seated height of 11.00 mm compared to 10.50 mm for the original part. This 0.50 mm (0.02") increase must be evaluated against board layout constraints and component clearance requirements. The case diameter and land pattern remain unchanged.

Q4: What packaging options are available for these substitutes?

A: The UUX2G2R2MNL1GS is available in Cut Tape (CT) and Digi-Reel® packaging. The ULH2W2R2MNL1GS is available in Tape & Reel (TR) packaging. Packaging selection should align with procurement and assembly process requirements.

Q5: Are both substitutes RoHS compliant?

A: Yes. Both UUX2G2R2MNL1GS and ULH2W2R2MNL1GS are ROHS3 compliant, meeting current regulatory requirements. Both maintain REACH Unaffected status and unlimited moisture sensitivity rating (MSL 1).

Q6: How do ripple current ratings compare?

A: The original EMKB401ADA2R2MHA0G specifies 26 mA @ 120 Hz and 39 mA @ 100 kHz. The UUX2G2R2MNL1GS provides 27 mA @ 120 Hz and 45.09 mA @ 10 kHz. The ULH2W2R2MNL1GS provides 20 mA @ 120 Hz and 30 mA @ 10 kHz. Ripple current capability should be verified against circuit requirements.

Q7: Which substitute should be selected for new designs?

A: For new designs, the UUX2G2R2MNL1GS is recommended as the primary choice due to parametric equivalence and active production status. The ULH2W2R2MNL1GS is suitable when enhanced thermal performance or voltage margin is required and height constraints permit the 11.00 mm profile.
