Substitute Part Grouping Explanation

Substitution for the RN55C2000CB14 is determined by strict equivalence in the following parameters:

• Resistance value: 200 Ohms (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.090" Dia × 0.240" L (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Military series compliance: MIL-R-10509/7, RN55 (exact match required)

The RN55C2000BB14 qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±0.1% versus ±0.25%).

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2000CB14 and RN55C2000BB14 are active production components manufactured by Vishay Dale under identical military specifications (MIL-R-10509/7). Selection between these parts should be based on tolerance requirements and inventory availability. The RN55C2000BB14 provides tighter tolerance (±0.1%) compared to the RN55C2000CB14 (±0.25%) while maintaining all other electrical and mechanical characteristics. Both parts carry identical compliance status: RoHS non-compliant and REACH Affected, with EAR99 export classification. Inventory availability favors the RN55C2000BB14 with 2700 units in stock versus 652 units for the RN55C2000CB14.

Frequently Asked Questions (FAQ)

Q: Can RN55C2000BB14 be used as a direct replacement for RN55C2000CB14?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (200 Ohms), power rating (1/8W), package type (Axial), physical dimensions (0.090" Dia × 0.240" L), temperature coefficient (±50ppm/°C), and operating temperature range (-65°C to 175°C). The RN55C2000BB14 offers improved tolerance specification.

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

A: The primary difference is tolerance specification. RN55C2000CB14 has ±0.25% tolerance, while RN55C2000BB14 has ±0.1% tolerance. All other parameters remain identical.

Q: Are there any compliance or certification differences?

A: No. Both parts share identical compliance status: RoHS non-compliant, REACH Affected, and EAR99 export classification. Both are manufactured to MIL-R-10509/7 military specifications.

Q: Will the substitute part fit in the same PCB footprint?

A: Yes. Both parts have identical axial package dimensions of 0.090" Dia × 0.240" L (2.29mm × 6.10mm) and two terminations, ensuring mechanical compatibility in existing circuit board layouts.

Q: Which part should be selected for new designs?

A: Selection depends on tolerance requirements. For applications requiring tighter tolerance control, RN55C2000BB14 (±0.1%) is appropriate. For applications where ±0.25% tolerance is acceptable, either part is suitable. Inventory availability also favors RN55C2000BB14 with significantly higher stock levels.
