Substitute Part Grouping Explanation

Substitution eligibility for the RN70D1000FRE6 is determined by the following critical parameters:

• Resistance value: 100 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.75W (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Physical dimensions: 0.180" Dia x 0.562" L (exact match required)
• Series compliance: MIL-R-10509/3 RN70 (exact match required)

The substitute part RN70C1000FB14 meets all critical electrical and mechanical parameters. The primary difference is packaging format (Bulk versus Tape & Reel) and temperature coefficient specification (±50ppm/°C versus ±100ppm/°C), which do not affect functional substitution in standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both RN70D1000FRE6 and RN70C1000FB14 are active production components from Vishay Dale with identical electrical specifications and military-grade certifications. Selection between these parts is determined by procurement and assembly requirements rather than electrical performance:

• RN70D1000FRE6 is supplied in Tape & Reel format, suitable for automated assembly processes
• RN70C1000FB14 is supplied in Bulk format, suitable for manual assembly or alternative handling requirements

Both components maintain RoHS non-compliant and REACH Affected status. The temperature coefficient difference (±100ppm/°C versus ±50ppm/°C) reflects manufacturing variance within the RN70 series and does not impact functional compatibility in standard circuit applications where both specifications are acceptable.

Frequently Asked Questions (FAQ)

Q: Can RN70C1000FB14 be used as a direct replacement for RN70D1000FRE6?

A: Yes. Both components share identical resistance (100 Ohms), tolerance (±1%), power rating (0.75W), composition (Metal Film), package type (Axial), physical dimensions (0.180" Dia x 0.562" L), operating temperature range (-65°C to 175°C), and military series compliance (MIL-R-10509/3, RN70). The packaging format difference (Tape & Reel versus Bulk) does not affect electrical or mechanical compatibility.

Q: What is the significance of the temperature coefficient difference?

A: The RN70D1000FRE6 specifies ±100ppm/°C while RN70C1000FB14 specifies ±50ppm/°C. Both values are within acceptable ranges for metal film resistors in the RN70 military series. Selection depends on circuit-level temperature stability requirements. If the design specifies ±100ppm/°C or lower, both parts are suitable.

Q: Are there packaging considerations for assembly?

A: Yes. RN70D1000FRE6 arrives in Tape & Reel format for automated pick-and-place assembly. RN70C1000FB14 arrives in Bulk format, requiring manual handling or alternative feeding systems. Verify assembly equipment compatibility before selection.

Q: Do both parts meet the same compliance standards?

A: Both components are RoHS non-compliant and REACH Affected. Both comply with MIL-R-10509/3 military specifications. Verify compliance requirements for your specific application before final selection.

Q: What inventory considerations apply?

A: RN70D1000FRE6 has 659 units in stock. RN70C1000FB14 has 756 units in stock. Both are active production components with current availability.
