Substitute Part Grouping Explanation

Substitution for the RN55C2000FB14 is determined by the following criteria:

• Resistance Value: Must be 200 Ohms
• Power Rating: Must be 0.125W (1/8W)
• Package Type: Must be Axial
• Physical Dimensions: Must match 0.090" Dia × 0.240" L
• Composition: Must be Metal Film
• Temperature Coefficient: Must be ±50ppm/°C
• Operating Temperature Range: Must be -65°C to 175°C
• Series Compliance: Must be MIL-R-10509/7, RN55 series
• Features: Must include Flame Retardant Coating, Military, Moisture Resistant, Safety

The RN55C2000BB14 qualifies as a substitute because it maintains all core electrical and mechanical parameters while offering improved tolerance (±0.1% versus ±1%), which represents a higher precision variant within the same product family.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2000FB14 and RN55C2000BB14 are active production components from Vishay Dale with identical military qualification and environmental compliance profiles. Selection between these parts depends on circuit tolerance requirements:

• RN55C2000FB14 is suitable for applications requiring ±1% tolerance within military specifications.
• RN55C2000BB14 is suitable for applications requiring tighter ±0.1% tolerance within the same military specifications.

Both components maintain identical thermal performance, operating temperature range, and physical form factor. Compliance status is equivalent: both are RoHS non-compliant and REACH Affected. Inventory availability differs, with RN55C2000BB14 showing higher stock levels (2,700 units versus 1,103 units).

Frequently Asked Questions (FAQ)

Q: Can RN55C2000BB14 replace RN55C2000FB14 in existing designs?

A: Yes. The RN55C2000BB14 maintains all core electrical and mechanical specifications of the RN55C2000FB14. The primary difference is improved tolerance (±0.1% versus ±1%), which is a performance enhancement rather than a limitation. Physical dimensions, power rating, temperature range, and military qualification are identical.

Q: What is the tolerance difference between these parts?

A: RN55C2000FB14 has ±1% tolerance, while RN55C2000BB14 has ±0.1% tolerance. The tighter tolerance of the substitute part provides higher precision for applications requiring closer resistance values.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0.090" diameter × 0.240" length (2.29mm × 6.10mm) in axial package configuration. They are mechanically interchangeable on PCBs designed for the RN55 series.

Q: Do both parts meet the same military specifications?

A: Yes. Both components comply with MIL-R-10509/7 specifications and are part of the RN55 military resistor series. They share identical temperature coefficients (±50ppm/°C) and operating temperature ranges (-65°C to 175°C).

Q: What is the compliance status for both parts?

A: Both parts are RoHS non-compliant and REACH Affected. Compliance status is identical between the main part and substitute.
