Parameter Comparison

Engineering Selection Recommendations

Both RN55D2402FRE6 and RN55E2402BB14 maintain active product status and identical compliance classifications (RoHS non-compliant, REACH Affected, ECCN EAR99). Selection between these parts depends on application-specific requirements:

RN55D2402FRE6 Selection Criteria:

• Tape & Reel packaging required for automated assembly processes
• Standard ±1% tolerance acceptable for circuit design
• Temperature coefficient of ±100ppm/°C meets application stability requirements

RN55E2402BB14 Selection Criteria:

• Bulk packaging suitable for manual assembly or kit configurations
• Tighter ±0.1% tolerance required for precision analog circuits
• Lower temperature coefficient of ±25ppm/°C necessary for temperature-sensitive applications
• Improved long-term stability and drift characteristics

Both parts satisfy military-grade specifications and maintain identical thermal operating ranges, physical form factors, and safety features.

Frequently Asked Questions (FAQ)

Q: Can RN55E2402BB14 directly replace RN55D2402FRE6 in existing designs?

A: Yes. Both parts share identical resistance values, power ratings, operating temperature ranges, physical dimensions, and axial package configurations. The RN55E2402BB14 provides improved tolerance and temperature coefficient performance. Packaging format differs (Bulk versus Tape & Reel), which affects assembly methodology but not electrical compatibility.

Q: What is the significance of the tolerance difference between ±1% and ±0.1%?

A: Tolerance defines the maximum allowable deviation from the nominal 24 kOhm resistance value. RN55D2402FRE6 allows ±240 ohms deviation; RN55E2402BB14 allows ±24 ohms deviation. Applications requiring tighter resistance accuracy specifications must use the ±0.1% part.

Q: How does temperature coefficient affect part selection?

A: Temperature coefficient quantifies resistance change per degree Celsius. RN55D2402FRE6 exhibits ±100ppm/°C; RN55E2402BB14 exhibits ±25ppm/°C. Over a 100°C temperature swing, RN55D2402FRE6 resistance may drift ±240 ohms, while RN55E2402BB14 drifts ±60 ohms. Temperature-sensitive circuits require the lower coefficient part.

Q: Are packaging format differences significant for circuit performance?

A: Packaging format (Tape & Reel versus Bulk) affects manufacturing and assembly processes but does not impact electrical performance. Tape & Reel packaging suits automated pick-and-place assembly; Bulk packaging suits manual assembly or small-quantity builds.

Q: Do both parts meet military specifications?

A: Yes. Both RN55D2402FRE6 and RN55E2402BB14 comply with MIL-R-10509/7 military resistor specifications and share identical feature sets including flame retardant coating, moisture resistance, and safety ratings.
