Substitute Part Grouping Explanation

Substitution eligibility for the RN55D6981FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 6.98 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Package configuration: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 175°C
• Physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Military series compliance: MIL-R-10509/7, RN55
• Feature set: Flame Retardant Coating, Military, Moisture Resistant, Safety

The identified substitute part RN55D6981FB14 maintains complete electrical and mechanical equivalence to the primary part. The only difference between these components is the packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Bulk packaging. Both parts share identical base product number RN55 and are manufactured by Vishay Dale under the same military specification.

Parameter Comparison

Engineering Selection Recommendations

Both RN55D6981FRE6 and RN55D6981FB14 are active production components manufactured by Vishay Dale with identical electrical performance and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability:

• RN55D6981FRE6 is supplied in Tape & Reel (TR) format, suitable for automated assembly processes and high-volume production environments.
• RN55D6981FB14 is supplied in Bulk packaging, suitable for manual assembly, prototyping, or applications where tape-and-reel format is not required.

Both parts maintain compliance with military specification MIL-R-10509/7 and carry identical RoHS non-compliant and REACH Affected designations. Current inventory levels are 1038 units for RN55D6981FRE6 and 1479 units for RN55D6981FB14.

Frequently Asked Questions (FAQ)

Q: Can RN55D6981FB14 be used as a direct replacement for RN55D6981FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: RN55D6981FRE6 uses Tape & Reel (TR) while RN55D6981FB14 uses Bulk packaging. Substitution is valid for any application where the packaging format does not impose constraints.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment and is standard for high-volume manufacturing. Bulk packaging contains loose components suitable for manual assembly or lower-volume applications. The electrical and mechanical properties of the component are identical regardless of packaging format.

Q: Are both parts compliant with military specifications?

A: Both RN55D6981FRE6 and RN55D6981FB14 conform to military specification MIL-R-10509/7 and are part of the RN55 military resistor series. Both parts feature flame retardant coating, moisture resistance, and safety-rated construction.

Q: What are the compliance implications of the RoHS non-compliant and REACH Affected designations?

A: Both parts carry identical compliance status: RoHS non-compliant and REACH Affected. These designations apply uniformly across both the main part and substitute. Compliance requirements must be evaluated at the system level based on end-use application and regulatory jurisdiction.

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

A: Yes, provided the application does not impose specific packaging format requirements. Both parts meet identical military specifications, temperature ranges, and performance criteria. Packaging format selection should be based on assembly process requirements rather than electrical performance.
