Key Parameters

Substitute Part Grouping Explanation

The RN70C2700BB14 qualifies as a substitute for the RN65C2700FRE6 based on the following substitution criteria:

Matching Parameters:

• Resistance value: 270 Ohms (identical)
• Composition: Metal Film (identical)
• Package type: Axial (identical)
• Temperature coefficient: ±50ppm/°C (identical)
• Operating temperature range: -65°C to 175°C (identical)
• Military-grade construction with flame retardant coating and moisture resistance (identical)

Enhanced Parameters:

• Tolerance: ±0.1% (tighter than ±1%)
• Power rating: 0.75W (3/4W) (higher than 0.5W)
• Military series: MIL-R-10509/3, RN70 (upgraded specification level)

The RN70C2700BB14 represents an upgrade path where all critical electrical and mechanical parameters remain compatible while offering improved tolerance and power handling capability.

Parameter Comparison

Engineering Selection Recommendations

Both the RN65C2700FRE6 and RN70C2700BB14 maintain active production status with Vishay Dale, ensuring long-term availability and supply chain stability. Both components share identical RoHS and REACH compliance classifications.

The RN70C2700BB14 provides enhanced specifications through tighter tolerance (±0.1% versus ±1%) and increased power rating (0.75W versus 0.5W) while maintaining all critical electrical and mechanical parameters. The upgrade to MIL-R-10509/3 specification level reflects enhanced military-grade performance standards.

Selection between these parts depends on circuit requirements: the RN65C2700FRE6 is suitable for applications where the 0.5W power rating and ±1% tolerance meet design specifications, while the RN70C2700BB14 is appropriate for designs requiring improved tolerance accuracy or higher power dissipation capability within the same 270 Ohm resistance value.

Frequently Asked Questions (FAQ)

Q: Can the RN70C2700BB14 directly replace the RN65C2700FRE6 in existing designs?

A: Yes. Both components share identical resistance, axial package configuration, temperature coefficient, and operating temperature range. The RN70C2700BB14 offers enhanced tolerance and power rating, making it functionally compatible for direct substitution.

Q: What is the significance of the tolerance difference between ±1% and ±0.1%?

A: Tolerance defines the maximum deviation from the nominal 270 Ohm resistance value. The RN70C2700BB14 with ±0.1% tolerance provides tighter resistance accuracy compared to the RN65C2700FRE6 with ±1% tolerance. Applications requiring precise resistance values benefit from the improved tolerance specification.

Q: Does the higher power rating of the RN70C2700BB14 affect circuit performance?

A: No. The 0.75W rating of the RN70C2700BB14 is a higher capability specification than the 0.5W rating of the RN65C2700FRE6. A component with higher power rating can safely operate in circuits designed for lower power dissipation without performance degradation.

Q: Are there packaging differences between these parts?

A: Both components use axial through-hole packaging with identical physical dimensions (0.180" diameter × 0.562" length). The primary packaging difference is that the RN65C2700FRE6 is supplied in Tape & Reel format while the RN70C2700BB14 is supplied in Bulk format. This affects procurement and handling but not electrical or mechanical compatibility.

Q: What military specifications apply to these resistors?

A: The RN65C2700FRE6 conforms to MIL-R-10509/2 specifications, while the RN70C2700BB14 conforms to the enhanced MIL-R-10509/3 specification level. Both meet military-grade standards for flame retardant coating, moisture resistance, and reliability requirements.
