RSS1E270MCN1GS Equivalent & Substitute Parts

Part Overview

The RSS1E270MCN1GS is a 27 µF, 25 V aluminum polymer capacitor manufactured by Nichicon in the FPCAP/RSS series. This surface mount radial can capacitor is designed for general purpose applications requiring stable capacitance and low equivalent series resistance. The part is currently active in production with 976 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to supply constraints, design flexibility, or inventory availability.

Substitute Part Grouping Explanation

Substitution eligibility for the RSS1E270MCN1GS is determined by strict equivalence across the following critical parameters:

• Capacitance value: 27 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR: 40 mOhm (exact match required)
• Lifetime specification: 2000 Hrs @ 105°C (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.248" Dia (6.30 mm), Height 0.236" (6.00 mm) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The VSG1E270MCB6357L from Chinsan (Elite) meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the RSS1E270MCN1GS and VSG1E270MCB6357L are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Availability: The VSG1E270MCB6357L has higher inventory (2036 units) compared to the RSS1E270MCN1GS (976 units)
• Ripple current performance: The RSS1E270MCN1GS provides 2.6 A @ 100 kHz, while the VSG1E270MCB6357L provides 2.1 A @ 100 kHz. Applications requiring maximum ripple current handling should prioritize the Nichicon part
• Moisture sensitivity: The VSG1E270MCB6357L specifies MSL 3 (168 Hours), providing defined moisture handling requirements for storage and assembly
• Manufacturer preference: Design specifications may mandate Nichicon components; in such cases, the RSS1E270MCN1GS is the required selection

Frequently Asked Questions (FAQ)

Q: Can the VSG1E270MCB6357L replace the RSS1E270MCN1GS in all applications?

A: Yes, provided the application does not exceed 2.1 A ripple current @ 100 kHz. The RSS1E270MCN1GS supports 2.6 A @ 100 kHz. Both parts are electrically and mechanically equivalent across all other specified parameters.

Q: Are there any PCB layout differences between these parts?

A: Both parts use identical physical dimensions (0.248" Dia, 0.236" height) and surface mount radial can packaging. The VSG1E270MCB6357L specifies a surface mount land size of 0.260" L x 0.260" W (6.60 mm x 6.60 mm). PCB footprints designed for standard 6.30 mm diameter radial cans will accommodate both parts.

Q: What is the significance of the MSL rating on the VSG1E270MCB6357L?

A: MSL 3 (168 Hours) indicates the part can be exposed to 85°C / 85% relative humidity for up to 168 hours before soldering. This specification is relevant for supply chain storage and assembly planning but does not affect electrical performance or long-term reliability in the final application.

Q: Are both parts suitable for -55°C to 105°C operating environments?

A: Yes. Both the RSS1E270MCN1GS and VSG1E270MCB6357L are rated for -55°C to 105°C continuous operation with 2000 hour lifetime at 105°C.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. ECCN classification is EAR99 for both parts, and HTSUS code is 8532.22.0020.
