Substitute Part Grouping Explanation

Substitution of the RN55C2003FRE6 is determined by the following critical parameters that must remain constant or improve:

Invariant Parameters (Must Match Exactly):

• Resistance value: 200 kOhms
• Power rating: 0.125W (1/8W)
• Package type: Axial
• Physical dimensions: 0.090" Dia x 0.240" L
• Operating temperature range: -65°C to 175°C
• Composition: Metal Film
• Military specification compliance: MIL-R-10509/7
• Features: Flame Retardant Coating, Moisture Resistant, Safety Rated

Parameters Allowed to Improve:

• Tolerance: May decrease (improve) from ±1% to ±0.1%
• Temperature coefficient: May decrease (improve) from ±50ppm/°C to ±25ppm/°C
• Packaging format: May change from Tape & Reel to Bulk or vice versa

The RN55E2003BB14 qualifies as a substitute part because it maintains all invariant parameters while providing improved tolerance and temperature coefficient specifications.

Parameter Comparison

Engineering Selection Recommendations

RN55C2003FRE6 (Main Part): Select this part when tape and reel packaging is required for automated assembly processes. The ±1% tolerance and ±50ppm/°C temperature coefficient meet standard military-grade specifications. This part is active and maintains full inventory availability.

RN55E2003BB14 (Substitute): Select this part when improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) are required for precision circuit applications. This substitute is suitable for circuits requiring tighter component matching or enhanced temperature stability. The bulk packaging format is appropriate for manual assembly or when tape and reel format is not required. Both parts comply with MIL-R-10509/7 military specification and maintain identical electrical and mechanical characteristics except for the specified improvements.

Both parts are manufactured by Vishay Dale, carry active product status, and are RoHS non-compliant with REACH affected status. Selection between these parts depends on packaging requirements and tolerance/temperature coefficient specifications needed for the application.

Frequently Asked Questions (FAQ)

Q: Can RN55E2003BB14 be used as a direct replacement for RN55C2003FRE6 in existing designs?

A: Yes. The RN55E2003BB14 is electrically and mechanically compatible with RN55C2003FRE6. Both components have identical resistance values, power ratings, physical dimensions, and operating temperature ranges. The substitute part provides improved tolerance and temperature coefficient specifications, making it suitable for direct substitution in circuit designs. The only difference is packaging format (bulk versus tape and reel).

Q: What is the difference between tape and reel packaging and bulk packaging?

A: Tape and reel (TR) packaging is used for automated pick-and-place assembly equipment, where components are wound on a continuous tape. Bulk packaging contains loose components suitable for manual assembly or hand-placement applications. Both packaging formats contain identical components; the difference is in delivery and handling format only.

Q: Are there any compliance or certification differences between these parts?

A: No. Both RN55C2003FRE6 and RN55E2003BB14 comply with identical military specifications (MIL-R-10509/7), feature identical flame retardant coating and moisture resistance, and carry identical RoHS and REACH status. Both parts are manufactured by Vishay Dale and maintain the same safety ratings.

Q: Why would I choose the RN55C2003FRE6 over the RN55E2003BB14 if the substitute has better specifications?

A: The RN55C2003FRE6 should be selected when tape and reel packaging is required for automated assembly processes. Additionally, if the circuit design has been validated with ±1% tolerance and ±50ppm/°C temperature coefficient specifications, using the main part maintains design consistency. The choice depends on packaging requirements and whether the improved specifications of the substitute are necessary for the application.

Q: Can these parts be used interchangeably in military applications?

A: Yes. Both parts comply with MIL-R-10509/7 military specification and are rated for military-grade applications. The RN55E2003BB14 substitute provides enhanced performance characteristics (tighter tolerance and lower temperature coefficient) while maintaining all military compliance requirements. Selection depends on packaging format and whether the improved specifications are required for the specific military application.

Q: What is the temperature coefficient and why does it matter?

A: Temperature coefficient (±50ppm/°C for the main part, ±25ppm/°C for the substitute) specifies how much the resistance value changes with temperature. A lower temperature coefficient indicates better stability across the operating temperature range. For precision circuits or applications with wide temperature variations, the substitute part with ±25ppm/°C provides superior performance.
