SS2R2M063ST Equivalent & Substitute Parts

Part Overview

The SS2R2M063ST is a 2.2 µF, 63 V aluminum electrolytic capacitor in radial configuration manufactured by Cornell Dubilier Electronics (CDE). The SS series is currently obsolete, necessitating the identification of equivalent substitute parts for ongoing design support and procurement continuity. Alternative parts must maintain functional compatibility while meeting modern compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based on strict electrical and mechanical compatibility within the following parameter constraints:

Critical Matching Parameters:

• Capacitance: 2.2 µF (exact match required)
• Voltage Rating: 63 V (minimum requirement)
• Tolerance: ±20% (electrical specification match)
• Package Type: Radial, Can (mechanical form factor)
• Mounting Type: Through Hole (board interface compatibility)
• Operating Temperature: -40°C ~ 85°C (functional operating envelope)
• Polarization: Polar (electrical polarity requirement)

Acceptable Variation Parameters:

• ESR (Equivalent Series Resistance): Variance acceptable within application context
• Lifetime @ Temperature: Higher values indicate enhanced reliability; lower values are not acceptable substitutes
• Lead Spacing: Physical layout adjustment may be required
• Physical Dimensions: Mounting space verification required

The SK2R2M063ST qualifies as an equivalent substitute based on matching all critical electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The SK2R2M063ST is a qualified equivalent substitute for the obsolete SS2R2M063ST. Selection basis:

• Electrical Compatibility: Identical capacitance (2.2 µF), tolerance (±20%), and voltage rating (63 V) ensure direct functional replacement.
• Thermal Performance: The SK2R2M063ST provides extended lifetime (2000 Hrs @ 85°C) compared to the original SS series (1000 Hrs @ 85°C), representing improved reliability.
• Compliance Status: Both parts maintain ROHS3 compliance and EAR99 classification, meeting regulatory requirements.
• Active Product Status: The SK series remains in active production through Cornell Dubilier Electronics, ensuring long-term procurement availability.
• Physical Footprint: PCB layout adjustment is required due to increased lead spacing (0.079" vs 0.059") and larger package dimensions (5.00 mm vs 4.00 mm diameter, 13.00 mm vs 7.00 mm height).

Frequently Asked Questions (FAQ)

Q: Why is the SS2R2M063ST being discontinued? A: The SS2R2M063ST is obsolete and no longer manufactured. The SK2R2M063ST provides equivalent electrical specifications with improved thermal longevity and active supply status.

Q: Can the SK2R2M063ST be used in place of the SS2R2M063ST without circuit modification? A: Electrical substitution is direct. However, PCB layout modifications are necessary to accommodate the larger physical dimensions and increased lead spacing of the SK series package.

Q: What are the key differences between these parts? A: The primary differences are physical dimensions, lead spacing, and thermal lifetime. The SK2R2M063ST is larger (5.00 mm vs 4.00 mm diameter) with wider lead spacing (2.00 mm vs 1.50 mm) and extended operational life rating (2000 Hrs vs 1000 Hrs @ 85°C).

Q: Are both parts RoHS3 compliant? A: Yes, both SS2R2M063ST and SK2R2M063ST meet ROHS3 compliance requirements.

Q: What is the moisture sensitivity level for these parts? A: The SS2R2M063ST moisture sensitivity level is not applicable. The SK2R2M063ST is classified as MSL 1 (Unlimited).

Q: Can these parts be used interchangeably on the same PCB? A: Direct PCB interchangeability is not possible without redesign. The SK2R2M063ST requires layout modifications due to increased package size and lead spacing. A new PCB layout with updated pad spacing and component placement is necessary.

Q: What applications are these capacitors suitable for? A: Both parts are specified for general-purpose applications requiring 2.2 µF capacitance at 63 V with radial through-hole configuration.
