Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55D2210FRE6 is determined by the following critical parameters:

• Resistance Value: Must be 221 Ohms (exact match required)
• Power Rating: Must be 0.125W (1/8W) minimum
• Package Type: Must be Axial configuration
• Composition: Must be Metal Film
• Operating Temperature Range: Must support -65°C to 175°C
• Series Compliance: Must conform to RN55 military series and MIL-R-10509/7 specification
• Physical Dimensions: Must match 0.090" Dia x 0.240" L (2.29mm x 6.10mm)

The RN55E2210BB14 qualifies as a direct substitute by meeting all mandatory electrical and mechanical parameters while offering enhanced tolerance specification (±0.1% versus ±1%) and improved temperature coefficient performance (±25ppm/°C versus ±100ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RN55D2210FRE6 and RN55E2210BB14 are active production components manufactured by Vishay Dale within the military-grade RN55 series. Selection between these parts should be based on the following criteria:

RN55D2210FRE6 is appropriate for applications where standard ±1% tolerance meets circuit requirements and Cut Tape packaging is preferred for automated assembly processes.

RN55E2210BB14 is appropriate for applications requiring tighter tolerance control (±0.1%) and superior temperature stability (±25ppm/°C). The Bulk packaging format suits manual assembly or lower-volume production environments. This part offers enhanced performance characteristics while maintaining full compliance with MIL-R-10509/7 military specification and identical thermal operating range.

Both parts maintain equivalent RoHS non-compliance and REACH Affected status, ensuring consistent regulatory treatment in procurement and supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can RN55E2210BB14 be used as a direct replacement for RN55D2210FRE6?

A: Yes. Both parts share identical resistance value (221 Ohms), power rating (0.125W), physical dimensions (0.090" Dia x 0.240" L), and operating temperature range (-65°C to 175°C). The RN55E2210BB14 provides superior tolerance (±0.1% versus ±1%) and temperature coefficient performance (±25ppm/°C versus ±100ppm/°C), making it functionally compatible and performance-enhanced for the same circuit application.

Q: What is the difference in packaging between these parts?

A: The RN55D2210FRE6 is supplied in Cut Tape (CT) format, suitable for high-speed automated pick-and-place assembly. The RN55E2210BB14 is supplied in Bulk format, appropriate for manual assembly or lower-volume production runs. Both use identical axial component geometry.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS non-compliant and REACH Affected status. They are both active production components manufactured by Vishay Dale under the same military specification (MIL-R-10509/7) and RN55 series designation.

Q: Which part should be selected for precision analog circuits?

A: The RN55E2210BB14 is the appropriate selection for precision applications due to its ±0.1% tolerance and ±25ppm/°C temperature coefficient, compared to the RN55D2210FRE6 specifications of ±1% tolerance and ±100ppm/°C temperature coefficient.

Q: Are the physical dimensions identical?

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