Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN55C2003CRE6 is determined by strict equivalence in the following parameters:

• Resistance Value: Must be 200 kOhms (exact match required)
• Power Rating: Must be 0.125W / 1/8W (exact match required)
• Package Type: Must be Axial configuration (exact match required)
• Composition: Must be Metal Film (exact match required)
• Series Compliance: Must belong to RN55 military series with MIL-R-10509/7 compliance
• Physical Dimensions: Must be 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Operating Temperature Range: Must support -65°C to 175°C minimum

Substitute parts may differ in tolerance specification (tighter tolerance acceptable), temperature coefficient (lower values acceptable), and packaging format (Bulk acceptable for Axial), provided all mandatory parameters remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

The RN55E2003BB14 serves as a direct electrical and mechanical substitute for the RN55C2003CRE6. Both components are manufactured by Vishay Dale within the military-qualified RN55 series and maintain identical resistance values, power ratings, physical dimensions, and operating temperature ranges.

The RN55E2003BB14 provides enhanced performance through tighter tolerance specification (±0.1% versus ±0.25%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C). These improvements represent upgrades suitable for applications requiring higher precision without compromising compatibility.

Both parts maintain active production status and comply with military specifications MIL-R-10509/7. The RN55E2003BB14 is REACH Affected and classified under ECCN EAR99 with HTSUS code 8533.21.0090. Selection between these parts depends on application tolerance requirements and packaging format preferences (standard versus bulk).

Frequently Asked Questions (FAQ)

Q: Can RN55E2003BB14 replace RN55C2003CRE6 in existing designs?

A: Yes. Both components share identical resistance value (200 kOhms), power rating (0.125W), physical dimensions (0.090" Dia x 0.240" L), package type (Axial), and operating temperature range (-65°C to 175°C). The RN55E2003BB14 is a direct mechanical and electrical substitute.

Q: What are the key differences between these parts?

A: The RN55E2003BB14 provides tighter tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). Packaging format differs (Bulk versus standard). All other specifications remain identical.

Q: Are both parts military-qualified?

A: Yes. Both RN55C2003CRE6 and RN55E2003BB14 comply with MIL-R-10509/7 military specifications and belong to the Vishay Dale RN55 military-grade resistor series.

Q: Does tolerance difference affect circuit performance?

A: Tolerance difference affects initial value accuracy. The RN55E2003BB14 with ±0.1% tolerance provides tighter initial value control compared to the RN55C2003CRE6 with ±0.25% tolerance. Selection depends on circuit precision requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.090" Dia x 0.240" L (2.29mm x 6.10mm) in axial configuration and are mechanically interchangeable.

Q: What is the difference between standard and bulk packaging?

A: Packaging format only affects order quantity and delivery configuration. Electrical and mechanical specifications remain unchanged. Bulk packaging typically accommodates larger order quantities.
