Substitute Part Grouping Explanation

Substitution of the RN55C2003CBSL is permissible with the RN55E2003BB14 based on the following criteria:

Maintained Parameters (Substitution Requirements):

• Resistance value: 200 kOhms (identical)
• Power rating: 0.125W, 1/8W (identical)
• Package configuration: Axial (identical)
• Physical dimensions: 0.090" Dia x 0.240" L (identical)
• Composition: Metal Film (identical)
• Operating temperature range: -65°C to 175°C (identical)
• Series family: Military, MIL-R-10509/7, RN55 (identical)
• Features: Flame Retardant Coating, Military, Moisture Resistant, Safety (identical)

Enhanced Characteristics in Substitute:

• Tolerance improvement: ±0.1% (versus ±0.25%)
• Temperature coefficient improvement: ±25ppm/°C (versus ±50ppm/°C)

The RN55E2003BB14 provides tighter tolerance and superior temperature stability while maintaining full mechanical and electrical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2003CBSL and RN55E2003BB14 maintain active product status and identical compliance classifications (RoHS non-compliant, REACH Affected, ECCN EAR99). Selection between these parts depends on circuit tolerance requirements:

• RN55C2003CBSL is suitable for applications where ±0.25% tolerance and ±50ppm/°C temperature coefficient meet design specifications.
• RN55E2003BB14 is appropriate for circuits requiring tighter tolerance control (±0.1%) and improved temperature stability (±25ppm/°C) within the same mechanical and thermal envelope.

Both components are manufactured by Vishay Dale within the military-grade RN55 series and provide equivalent mechanical fit and thermal performance across the -65°C to 175°C operating range.

Frequently Asked Questions (FAQ)

Q: Can RN55E2003BB14 directly replace RN55C2003CBSL in existing assemblies?

A: Yes. Both parts share identical resistance value (200 kOhms), power rating (0.125W), axial package configuration, and physical dimensions (0.090" Dia x 0.240" L). No PCB layout or mechanical modifications are required.

Q: What is the primary difference between these two parts?

A: The RN55E2003BB14 provides improved tolerance (±0.1% versus ±0.25%) and superior temperature coefficient (±25ppm/°C versus ±50ppm/°C). All other electrical and mechanical specifications remain identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS status (non-compliant), REACH status (Affected), and ECCN classification (EAR99). Both are certified to MIL-R-10509/7 military standards.

Q: Which part should be selected for precision analog circuits?
