Substitute Part Grouping Explanation

The RN55E3000BB14 qualifies as a direct substitute for the RN55D3000FRE6 based on the following critical parameters:

  • Resistance Value: Both parts are 300 Ohms
  • Power Rating: Both rated at 0.125W (1/8W)
  • Composition: Both are metal film construction
  • Operating Temperature Range: Both operate from -65°C to 175°C
  • Package Type: Both use axial through-hole configuration
  • Physical Dimensions: Identical at 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
  • Military Series: Both conform to MIL-R-10509/7 specification and RN55 base series
  • Features: Both include flame retardant coating, moisture resistance, and safety construction

The RN55E3000BB14 provides enhanced tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±100ppm/°C), making it suitable for applications requiring tighter performance specifications. The primary difference is packaging format: RN55D3000FRE6 is supplied in Tape & Reel format, while RN55E3000BB14 is supplied in Bulk format.

Engineering Selection Recommendations

Both the RN55D3000FRE6 and RN55E3000BB14 are active production components with identical electrical and mechanical specifications for core functional parameters. Selection between these parts should be based on:

RN55D3000FRE6 is appropriate when Tape & Reel packaging is required for automated assembly processes or when the ±1% tolerance specification is sufficient for circuit requirements.

RN55E3000BB14 is appropriate when tighter tolerance (±0.1%) and improved temperature coefficient stability (±25ppm/°C) are required for precision applications, or when Bulk packaging format is acceptable for manual assembly or rework operations.

Both parts maintain identical RoHS non-compliant status, REACH affected designation, and military-grade construction. No compliance or certification differences exist between the two options.

Frequently Asked Questions (FAQ)

Q: Can RN55E3000BB14 be used as a direct replacement for RN55D3000FRE6 in existing designs?

A: Yes. Both parts share identical resistance value, power rating, operating temperature range, physical dimensions, and axial package configuration. The RN55E3000BB14 provides enhanced tolerance and temperature coefficient performance, making it functionally compatible and electrically superior for the same circuit application.

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

A: The main differences are packaging format (Tape & Reel versus Bulk) and performance specifications. RN55E3000BB14 offers ±0.1% tolerance compared to ±1%, and ±25ppm/°C temperature coefficient compared to ±100ppm/°C. These enhancements make RN55E3000BB14 suitable for precision applications requiring tighter component specifications.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS non-compliant status, REACH affected designation, and military specification compliance per MIL-R-10509/7. Both are rated for the same operating temperature range and feature identical flame retardant coating and moisture resistance properties.

Q: Which part should be selected for automated assembly?

A: RN55D3000FRE6 in Tape & Reel format is optimized for automated pick-and-place assembly processes. RN55E3000BB14 in Bulk format is suitable for manual assembly or rework operations where individual component handling is acceptable.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts measure 0.090" diameter by 0.240" length (2.29mm x 6.10mm) and use identical axial through-hole configuration, ensuring mechanical compatibility in PCB layouts and component placement.
