Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55E10R0FRE6 is determined by the following critical parameters:

• Resistance value: 10 Ohms (exact match required)
• Power rating: 0.125W minimum (equal or higher acceptable)
• Composition: Metal Film (required for temperature stability and tolerance performance)
• Operating temperature range: -65°C to 175°C (minimum required)
• Package type: Axial (mechanical and electrical interface requirement)
• Physical dimensions: 0.090" Dia × 0.240" L (PCB layout compatibility)
• Series compliance: MIL-R-10509/7 military specification
• Features: Flame retardant coating, moisture resistance, safety rating (application requirement)

The RN55E10R0BB14 qualifies as a substitute based on identical resistance, power rating, composition, temperature range, package type, dimensions, series compliance, and features. The tolerance specification differs (±0.1% versus ±1%), representing an upgrade in precision capability while maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55E10R0FRE6 and RN55E10R0BB14 are active production components from Vishay Dale with identical military specification compliance (MIL-R-10509/7). Selection between these parts should be based on:

Packaging format requirements: The RN55E10R0FRE6 is supplied in Tape & Reel format, suitable for automated assembly processes. The RN55E10R0BB14 is supplied in Bulk format, appropriate for manual assembly or alternative handling methods.

Tolerance requirements: The RN55E10R0FRE6 provides ±1% tolerance. The RN55E10R0BB14 provides ±0.1% tolerance, offering superior precision for applications requiring tighter resistance values. The ±0.1% tolerance is a performance upgrade and does not compromise compatibility with designs specified for ±1%.

Regulatory compliance: Both parts maintain identical RoHS non-compliant and REACH Affected status, ensuring consistent compliance documentation across substitution.

Frequently Asked Questions (FAQ)

Q: Can RN55E10R0BB14 replace RN55E10R0FRE6 in existing designs?

A: Yes. The RN55E10R0BB14 is electrically and mechanically compatible. Identical resistance (10 Ohms), power rating (0.125W), composition (metal film), temperature range (-65°C to 175°C), package type (axial), and physical dimensions (0.090" Dia × 0.240" L) ensure direct substitution. The improved tolerance (±0.1% versus ±1%) represents a performance upgrade.

Q: What is the primary difference between these two parts?

A: The primary differences are packaging format (Tape & Reel versus Bulk) and tolerance specification (±1% versus ±0.1%). All electrical and mechanical parameters are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts share identical RoHS status (non-compliant), REACH status (affected), ECCN classification (EAR99), and HTSUS code (8533.21.0090). Military specification compliance (MIL-R-10509/7) is identical.

Q: Which packaging format should I select?

A: Select Tape & Reel (RN55E10R0FRE6) for automated assembly lines requiring continuous component feeding. Select Bulk (RN55E10R0BB14) for manual assembly, kit builds, or applications where tape packaging is not required.

Q: Is the ±0.1% tolerance of RN55E10R0BB14 necessary for my application?

A: The ±0.1% tolerance is required only if your circuit design specifies tolerance tighter than ±1%. If your design accepts ±1% tolerance, either part is suitable. The ±0.1% part will not cause compatibility issues in designs specified for ±1%.
