Substitute Part Grouping Explanation

Substitute parts for the RN55D90R9FRE6 are qualified based on the following criteria:

• Identical resistance value: 90.9 Ohms
• Identical tolerance: ±1%
• Identical power rating: 0.125W (1/8W)
• Identical composition: Metal Film
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -65°C to 175°C
• Identical package type: Axial
• Identical physical dimensions: 0.090" Dia × 0.240" L (2.29mm × 6.10mm)
• Identical number of terminations: 2
• Same military series: MIL-R-10509/7, RN55
• Identical features: Flame Retardant Coating, Military, Moisture Resistant, Safety

The primary difference between the main part and substitute is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Bulk format. Both maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55D90R9FRE6 and RN55D90R9FB14 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on procurement and assembly requirements:

• RN55D90R9FRE6 (Tape & Reel): Suitable for automated assembly processes requiring tape-and-reel packaging
• RN55D90R9FB14 (Bulk): Suitable for manual assembly or applications where bulk packaging is preferred

Both parts maintain identical performance in military-grade applications and comply with MIL-R-10509/7 specifications. Regulatory compliance status (RoHS non-compliant, REACH Affected) is identical across both variants.

Frequently Asked Questions (FAQ)

Q: Can RN55D90R9FB14 be used as a direct replacement for RN55D90R9FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk vs. Tape & Reel). Substitution is valid for any application where the RN55D90R9FRE6 is specified, provided assembly equipment can accommodate the bulk packaging format.

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

A: Tape & Reel (TR) packaging supplies components on a continuous tape wound on a reel, optimized for automated pick-and-place assembly. Bulk packaging supplies loose components, typically used for manual assembly or lower-volume applications.

Q: Are the physical dimensions identical between substitute parts?

A: Yes. Both parts have identical axial dimensions of 0.090" Dia × 0.240" L (2.29mm × 6.10mm), ensuring identical PCB footprint and mounting compatibility.

Q: Do both parts meet military specifications?

A: Yes. Both RN55D90R9FRE6 and RN55D90R9FB14 are manufactured to MIL-R-10509/7 specification and feature identical military-grade construction with flame retardant coating and moisture resistance.

Q: What is the temperature operating range for these resistors?

A: Both parts operate across -65°C to 175°C, suitable for military and high-reliability applications requiring extended temperature performance.
