Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C2000DBSL is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 200 Ohms
• Power rating: 0.125W (1/8W)
• Package type: Axial
• Physical dimensions: 0.090" Dia x 6.10mm L
• Composition: Metal Film
• Operating temperature range: -65°C to 175°C
• Temperature coefficient: ±50ppm/°C
• Military series compliance: MIL-R-10509/7, RN55

Allowable Variation:

• Tolerance: May be tighter (lower value) than the original ±0.5% specification without affecting circuit compatibility

The RN55C2000BB14 qualifies as a direct substitute because it maintains all mandatory parameters while offering improved tolerance performance (±0.1% versus ±0.5%).

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2000DBSL and RN55C2000BB14 are active production parts from the same manufacturer and series. Selection between these parts should be based on tolerance requirements:

• RN55C2000DBSL is appropriate for applications where ±0.5% tolerance meets circuit specifications and cost optimization is prioritized.
• RN55C2000BB14 is appropriate for applications requiring tighter tolerance control (±0.1%) or where higher precision resistor performance is specified in design requirements.

Both parts maintain identical compliance status (RoHS non-compliant, REACH Affected) and are suitable for military applications under MIL-R-10509/7 specification. Inventory availability should be considered: RN55C2000BB14 has 2700 units in stock compared to 1114 units for the main part.

Frequently Asked Questions (FAQ)

Q: Can RN55C2000BB14 be used as a direct replacement for RN55C2000DBSL?

A: Yes. The RN55C2000BB14 is a direct substitute. It maintains all critical electrical and mechanical parameters, including resistance value, power rating, package type, physical dimensions, operating temperature range, and military series compliance. The only difference is improved tolerance (±0.1% versus ±0.5%), which is a performance enhancement.

Q: What is the significance of the tolerance difference between these parts?

A: Tolerance defines the acceptable deviation from the nominal 200 Ohm resistance value. RN55C2000DBSL allows ±0.5% deviation (198–202 Ohms), while RN55C2000BB14 allows ±0.1% deviation (199.8–200.2 Ohms). Tighter tolerance provides greater precision for circuits sensitive to resistance variation.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0.090" diameter by 0.240" length (2.29mm x 6.10mm), ensuring identical PCB footprint and mounting compatibility.

Q: Do these parts have the same compliance certifications?

A: Yes. Both parts are RoHS non-compliant and REACH Affected, with identical military series designation (MIL-R-10509/7, RN55).

Q: Can either part be used in high-temperature applications?

A: Yes. Both parts operate across the -65°C to 175°C temperature range with ±50ppm/°C temperature coefficient, suitable for military and industrial high-temperature environments.
