ECA-2CM2R2I Equivalent & Substitute Parts

Part Overview

The ECA-2CM2R2I is a 2.2 µF 160 V aluminum electrolytic capacitor in radial configuration 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. Equivalent and substitute parts are necessary when the original part becomes unavailable, when packaging requirements differ, or when upgraded electrical specifications are required for enhanced circuit reliability.

Substitute Part Grouping Explanation

Substitute parts for the ECA-2CM2R2I are grouped into three categories based on allowed electrical and mechanical parameters:

Direct Equivalent (Same Specifications)

• ECA-2CM2R2: Identical electrical specifications and physical dimensions. Differs only in packaging format (Bulk vs. Cut Tape). This part maintains 160 V rating, 2.2 µF capacitance, and identical thermal performance.

Upgraded Voltage Rating (Higher Voltage, Same Capacitance)

• ECA-2EM2R2: Panasonic part with 250 V rating instead of 160 V. Maintains 2.2 µF capacitance, identical physical dimensions, and same thermal lifetime. Suitable for circuits requiring higher voltage margin.

Cross-Manufacturer Alternatives (Different Manufacturer, Upgraded Specifications)

• UPS2D2R2MED1TD: Nichicon part with 200 V rating and enhanced thermal performance (2000 Hrs @ 105°C vs. 85°C). Slightly taller (0.492" vs. 0.480"). Product status is Obsolete.
• UPW2D2R2MED1TD: Nichicon part with identical specifications to UPS2D2R2MED1TD. Product status is Obsolete.
• UVR2E2R2MED1TD: Nichicon part with 250 V rating and 2000 Hrs @ 85°C thermal rating. Slightly taller (0.492" vs. 0.480"). Product status is Obsolete.

Substitution is permitted when capacitance, tolerance, polarization, lead spacing, and mounting type remain constant. Voltage rating may be increased. Physical height variation of 0.012" (0.30mm) is within acceptable tolerance for through-hole mounting.

Engineering Selection Recommendations

Primary Selection: ECA-2CM2R2 This Panasonic part is the direct equivalent to ECA-2CM2R2I with identical electrical and mechanical specifications. It maintains Active product status and ROHS3 compliance. Selection differs only in packaging format (Bulk vs. Cut Tape), making it suitable for high-volume applications.

Secondary Selection: ECA-2EM2R2 This Panasonic part provides upgraded voltage rating (250 V vs. 160 V) while maintaining identical physical dimensions and thermal performance. It is Active in production and ROHS3 compliant. This part is appropriate when circuit design requires higher voltage margin or when 160 V parts are unavailable.

Cross-Manufacturer Alternatives: UPS2D2R2MED1TD, UPW2D2R2MED1TD, UVR2E2R2MED1TD These Nichicon parts are classified as Obsolete. While they meet the core electrical specifications (2.2 µF, ±20% tolerance, polar configuration), their obsolete status indicates limited availability and potential supply chain risk. Physical height is 0.012" (0.30mm) greater than the original part. These parts are suitable only when no active alternatives are available and existing inventory is confirmed.

All substitute parts maintain ROHS3 compliance and are suitable for general-purpose applications with identical lead spacing and mounting type.

Frequently Asked Questions (FAQ)

Q: Can ECA-2CM2R2 be used as a direct replacement for ECA-2CM2R2I? A: Yes. Both parts have identical capacitance (2.2 µF), voltage rating (160 V), tolerance (±20%), thermal performance (2000 Hrs @ 85°C), physical dimensions, and lead spacing. The only difference is packaging format (Bulk vs. Cut Tape). Both are Active products from Panasonic.

Q: Is ECA-2EM2R2 compatible with circuits designed for ECA-2CM2R2I? A: Yes. ECA-2EM2R2 has the same capacitance, tolerance, physical dimensions, and lead spacing. The 250 V rating is higher than the 160 V requirement, which is acceptable in circuit design. Both parts have identical thermal performance and physical footprint.

Q: Why are the Nichicon parts (UPS2D2R2MED1TD, UPW2D2R2MED1TD, UVR2E2R2MED1TD) listed as Obsolete? A: Obsolete status indicates these parts are no longer in active production. While they meet the core electrical specifications, their availability is limited and supply cannot be guaranteed. These parts should be used only when active alternatives are unavailable.

Q: What is the physical height difference between ECA-2CM2R2I and the Nichicon alternatives? A: ECA-2CM2R2I has a maximum seated height of 0.480" (12.20mm). The Nichicon parts (UPS2D2R2MED1TD, UPW2D2R2MED1TD, UVR2E2R2MED1TD) have a maximum seated height of 0.492" (12.50mm), a difference of 0.012" (0.30mm). This variation is within acceptable tolerance for through-hole PCB mounting.

Q: Do all substitute parts maintain the same lead spacing? A: Yes. All listed substitute parts maintain 0.098" (2.50mm) lead spacing, ensuring compatibility with existing PCB layouts designed for ECA-2CM2R2I.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of ECA-2CM2R2I.

Q: What is the difference between UPS2D2R2MED1TD and UPW2D2R2MED1TD? A: Both parts have identical electrical specifications (2.2 µF, 200 V, ±20% tolerance, 2000 Hrs @ 105°C) and physical dimensions. They differ only in series designation (UPS vs. UPW). Both are Nichicon products with Obsolete status.
