Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN55C2003DBSL is permissible when the following core parameters remain constant or improve:

• Resistance value: 200 kOhms (exact match required)
• Power rating: 0.125W minimum (equal or higher acceptable)
• Package configuration: Axial through-hole (exact match required)
• Composition: Metal film (exact match required)
• Operating temperature range: -65°C to 175°C minimum (equal or wider acceptable)
• Series compliance: Military RN55 series, MIL-R-10509/7 specification

The RN55E2003BB14 qualifies as a direct substitute because it maintains all core parameters while providing improved tolerance (±0.1% versus ±0.5%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C), resulting in superior electrical stability.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2003DBSL and RN55E2003BB14 maintain active product status and identical compliance profiles (RoHS non-compliant, REACH Affected, ECCN EAR99). Selection between these parts depends on application-specific tolerance and stability requirements. The RN55E2003BB14 provides superior tolerance specification (±0.1%) and lower temperature coefficient (±25ppm/°C), making it suitable for precision circuit applications requiring tighter resistance stability. The RN55C2003DBSL remains appropriate for general-purpose military applications where ±0.5% tolerance is acceptable. Both parts are manufactured by Vishay Dale and comply with MIL-R-10509/7 military specifications.

Frequently Asked Questions (FAQ)

Q: Can RN55E2003BB14 replace RN55C2003DBSL in existing designs?

A: Yes. The RN55E2003BB14 is a direct substitute with identical resistance value (200 kOhms), power rating (0.125W), package configuration (axial), and physical dimensions. The improved tolerance and temperature coefficient represent performance enhancements rather than compatibility issues.

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

A: The RN55E2003BB14 offers tighter tolerance (±0.1% versus ±0.5%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). Both parts are metal film military-grade resistors with identical operating temperature ranges and package specifications.

Q: Are there any physical dimension differences?

A: No. Both parts share identical axial package dimensions of 0.090" diameter by 0.240" length (2.29mm x 6.10mm).

Q: Do both parts meet the same military specifications?

A: Yes. Both RN55C2003DBSL and RN55E2003BB14 comply with MIL-R-10509/7 specifications and are part of the Vishay Dale Military RN55 series.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS non-compliant and REACH Affected, with ECCN classification EAR99 and HTSUS code 8533.21.0090.
