Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C47R0DB14 is determined by the following critical parameters:

• Resistance Value: Must be 47 Ohms (exact match required)
• Power Rating: Must be 0.125W / 1/8W (exact match required)
• Package Type: Must be Axial (exact match required)
• Physical Dimensions: Must be 0.090" Dia × 0.240" L (exact match required)
• Composition: Must be Metal Film (exact match required)
• Operating Temperature Range: Must support -65°C to 175°C (exact match required)
• Temperature Coefficient: Must be ±50ppm/°C (exact match required)
• Series Compliance: Must conform to MIL-R-10509/7 and RN55 series standards

The RN55C47R0BB14 qualifies as a direct substitute. While it features a tighter tolerance specification (±0.1% versus ±0.5%), all electrical and mechanical parameters remain identical, and it maintains full compliance with military specifications and environmental requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C47R0DB14 and RN55C47R0BB14 maintain Active product status and are manufactured by Vishay Dale under identical military specifications (MIL-R-10509/7). Both parts carry identical compliance certifications: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090.

The RN55C47R0BB14 offers improved tolerance performance (±0.1% versus ±0.5%) while maintaining all other electrical and mechanical characteristics. Selection between these parts depends on circuit tolerance requirements and inventory availability. The RN55C47R0BB14 currently maintains higher inventory levels (1568 units versus 860 units).

Frequently Asked Questions (FAQ)

Q: Can RN55C47R0BB14 be used as a direct replacement for RN55C47R0DB14?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 47 Ohm resistance, 1/8W power rating, metal film composition, axial package, identical physical dimensions, and full military specification compliance. The substitute features tighter tolerance specification.

Q: What is the difference between ±0.5% and ±0.1% tolerance?

A: Tolerance defines the acceptable deviation from the nominal 47 Ohm resistance value. RN55C47R0DB14 allows deviation up to ±0.235 Ohms; RN55C47R0BB14 allows deviation up to ±0.047 Ohms. Applications requiring tighter resistance accuracy benefit from the ±0.1% specification.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.090" diameter × 0.240" length (2.29mm × 6.10mm) and use identical axial packaging, ensuring drop-in compatibility in PCB layouts and through-hole assemblies.

Q: Do both parts meet military specifications?

A: Yes. Both RN55C47R0DB14 and RN55C47R0BB14 conform to MIL-R-10509/7 and belong to the RN55 military resistor series. Both feature flame retardant coating, moisture resistance, and safety-rated construction.

Q: What compliance certifications apply to both parts?

A: Both parts share identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090. No compliance differences exist between the two parts.
