Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55E2210CBSL is determined by strict adherence to the following parameters:

• Resistance Value: Must be 221 Ohms
• Power Rating: Must be 0.125W (1/8W)
• Composition: Must be Metal Film
• Package Type: Must be Axial
• Temperature Coefficient: Must be ±25ppm/°C
• Operating Temperature Range: Must be -65°C to 175°C
• Series Compliance: Must conform to Military, MIL-R-10509/7, RN55 specifications
• Physical Dimensions: Must be 0.090" Dia x 0.240" L (2.29mm x 6.10mm)

The RN55E2210BB14 qualifies as a direct substitute based on these parameters. Tolerance variation (±0.1% versus ±0.25%) represents an upgrade in precision while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55E2210CBSL and RN55E2210BB14 are active production components from Vishay Dale with identical military qualification and environmental specifications. Selection between these parts is based on tolerance requirements:

• RN55E2210CBSL: Select when ±0.25% tolerance meets circuit specifications and cost optimization is prioritized.
• RN55E2210BB14: Select when ±0.1% tolerance is required for improved precision in critical applications. This represents a tolerance upgrade while maintaining all other electrical and mechanical parameters.

Both components comply with MIL-R-10509/7 military standards, feature identical thermal characteristics, and are suitable for the full operating temperature range of -65°C to 175°C. RoHS non-compliance status is identical for both parts.

Frequently Asked Questions (FAQ)
