ECA-2DM2R2 Equivalent & Substitute Parts

Part Overview

The ECA-2DM2R2 is a 2.2 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This through-hole component is rated for 2000 hours at 85°C and is designed for general-purpose applications. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are necessary when the original part becomes unavailable, when higher voltage ratings or extended temperature ranges are required, or when alternative manufacturers' components are preferred for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECA-2DM2R2 are grouped based on the following allowed electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance: 2.2 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.098" (2.50mm) (exact match required)
• Size / Dimension: 0.248" Dia (6.30mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)

Secondary Substitution Parameters (allowable variations):

• Voltage - Rated: 200 V or higher (equal or greater voltage rating acceptable)
• Operating Temperature Range: -25°C ~ 85°C or wider (equal or extended range acceptable)
• Lifetime @ Temperature: 2000 Hrs @ 85°C or greater (equal or extended lifetime acceptable)
• Height - Seated (Max): 0.480" (12.20mm) or less (equal or smaller height acceptable for PCB clearance)

All substitute parts maintain identical core electrical characteristics (capacitance, tolerance, polarization) and mechanical footprint (lead spacing, diameter) to ensure direct PCB compatibility.

Parameter Comparison

Engineering Selection Recommendations

Active Production Parts (Preferred):

ECA-2EHG2R2 and ECA-2EM2R2 are both Panasonic products with active production status. ECA-2EHG2R2 offers extended operating temperature range (-25°C ~ 105°C) and higher temperature lifetime rating (2000 Hrs @ 105°C), making it suitable for applications requiring enhanced thermal performance. ECA-2EM2R2 maintains the same operating temperature range as the original part (-25°C ~ 85°C) while providing 250 V rated voltage. Both parts are ROHS3 compliant and REACH unaffected.

225CKH250M is a Cornell Dubilier / Illinois Capacitor product with active production status, ROHS3 compliance, and REACH unaffected status. It provides 250 V rated voltage and 2000 Hrs @ 105°C lifetime rating. Height dimension is 0.492" (12.50mm), which is 0.012" taller than the original part. This part carries MSL 1 (Unlimited) rating.

Obsolete Parts (Not Recommended for New Designs):

UVR2D2R2MED and UVR2E2R2MED are Nichicon products with obsolete product status. These parts should not be selected for new designs or long-term production applications. UVR2D2R2MED matches the original 200 V rating and 85°C operating temperature. UVR2E2R2MED provides 250 V rated voltage. Both are ROHS3 compliant and REACH unaffected. Height dimensions are 0.492" (12.50mm), exceeding the original part specification.

Frequently Asked Questions (FAQ)

Q: Can ECA-2EHG2R2 or ECA-2EM2R2 be used as direct replacements for ECA-2DM2R2?

A: Yes. Both parts maintain identical capacitance (2.2 µF), tolerance (±20%), polarization (Polar), lead spacing (0.098" / 2.50mm), diameter (0.248" / 6.30mm), and mounting type (Through Hole, Radial Can). ECA-2EHG2R2 and ECA-2EM2R2 provide equal or higher voltage ratings (250 V vs. 200 V), which is acceptable for direct substitution. Height dimensions for both parts match the original specification at 0.480" (12.20mm).

Q: What is the difference between ECA-2EHG2R2 and ECA-2EM2R2?

A: Both are Panasonic products with identical electrical and mechanical specifications except for operating temperature range and lifetime rating. ECA-2EHG2R2 operates from -25°C ~ 105°C with 2000 Hrs @ 105°C lifetime, while ECA-2EM2R2 operates from -25°C ~ 85°C with 2000 Hrs @ 85°C lifetime. Select ECA-2EHG2R2 for applications requiring extended temperature performance.

Q: Can 225CKH250M be used as a substitute despite its taller height?

A: 225CKH250M has a height of 0.492" (12.50mm) compared to the original 0.480" (12.20mm). This 0.012" difference must be evaluated against PCB layout constraints and available vertical clearance. If PCB design accommodates the additional height, 225CKH250M is electrically compatible. Verify mechanical fit before implementation.

Q: Why are UVR2D2R2MED and UVR2E2R2MED marked as obsolete?

A: Both Nichicon UVR series parts have obsolete product status, indicating they are no longer in active production. These parts should not be selected for new designs or applications requiring long-term component availability. Use active production alternatives (ECA-2EHG2R2, ECA-2EM2R2, or 225CKH250M) instead.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and REACH unaffected status, matching the regulatory compliance of the original ECA-2DM2R2.

Q: What is the inventory status of these substitute parts?

A: ECA-2EHG2R2 has 8366 pcs in stock, ECA-2EM2R2 has 8709 pcs in stock, 225CKH250M has 56401 pcs in stock, UVR2D2R2MED has 3920 pcs in stock, and UVR2E2R2MED has 912 pcs in stock. Inventory levels should be verified at time of procurement.
