Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2003FR36 and RN55E2003BB14 are active military-grade components from Vishay Dale's RN55 series, maintaining identical electrical performance within their specified operating ranges and compliance certifications. The RN55E2003BB14 provides improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring tighter component accuracy. The primary distinction is packaging format: the RN55C2003FR36 is supplied in Tape & Reel format for automated assembly, while the RN55E2003BB14 is supplied in Bulk format. Both parts maintain identical physical dimensions, military specifications, and environmental protection features. Selection between these parts should be based on packaging requirements and tolerance specifications for the intended application.

Frequently Asked Questions (FAQ)

Q: Can RN55E2003BB14 directly replace RN55C2003FR36 in existing designs?

A: Yes. Both parts share identical resistance values (200 kOhms), power ratings (0.125W), physical dimensions (0.090" Dia x 0.240" L), package type (Axial), and operating temperature ranges (-65°C to 175°C). The RN55E2003BB14 offers improved tolerance and temperature coefficient specifications.

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

A: The main difference is packaging format. RN55C2003FR36 is supplied in Tape & Reel (TR) format for automated pick-and-place assembly, while RN55E2003BB14 is supplied in Bulk format. Electrically and mechanically, both parts are equivalent.

Q: Does the tighter tolerance of RN55E2003BB14 affect compatibility?

A: No. The ±0.1% tolerance of RN55E2003BB14 is a superior specification compared to the ±1% tolerance of RN55C2003FR36. Any circuit designed for the RN55C2003FR36 will function with the RN55E2003BB14, with improved accuracy.

Q: Are both parts compliant with military standards?

A: Yes. Both parts are manufactured to MIL-R-10509/7 specifications and are part of the military-grade RN55 series. Both maintain identical military certifications, flame retardant coating, and moisture resistance features.

Q: What packaging considerations should be evaluated when selecting between these parts?

A: The RN55C2003FR36 in Tape & Reel format is optimized for high-volume automated assembly lines. The RN55E2003BB14 in Bulk format is suitable for manual assembly, repair, or lower-volume applications. Packaging selection should align with assembly process requirements.
