• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 175°C
• Package: Axial through-hole
• Physical dimensions: 0.090" Dia × 0.240" L
• Series compliance: Military, MIL-R-10509/7, RN55 base product

The RN55D3010FB14 meets all specified electrical and mechanical parameters, making it a direct parametric equivalent for applications requiring the RN55D3010FBSL.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55D3010FBSL and RN55D3010FB14 are active production components manufactured by Vishay Dale within the military-grade RN55 series. Selection between these parts should be based on inventory availability and supply chain requirements. The RN55D3010FB14 currently maintains higher stock levels (4780 units) compared to the RN55D3010FBSL (1029 units), making it suitable for high-volume procurement scenarios. Both parts carry identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090. No performance differentiation exists between these components for military and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can RN55D3010FB14 be used as a direct replacement for RN55D3010FBSL?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (301 Ohms, ±1%, 0.125W), temperature characteristics (±100ppm/°C, -65°C to 175°C), physical dimensions (0.090" Dia × 0.240" L), and military-grade construction. They are interchangeable in circuit design and PCB layout.

Q: Are there any packaging or lead configuration differences?

A: No. Both components use identical axial through-hole packaging with two terminations and matching physical dimensions. PCB footprints and assembly processes remain unchanged.

Q: What is the basis for substitution between these part numbers?

A: Substitution is based on complete equivalence across all specified electrical parameters (resistance, tolerance, power rating, temperature coefficient), mechanical specifications (package type, dimensions, terminations), and series compliance (Military, MIL-R-10509/7, RN55). Both parts are manufactured by Vishay Dale with identical feature sets.

Q: Do these parts have different compliance or certification status?

A: No. Both parts share identical compliance designations: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS code 8533.21.0090. Regulatory and trade status are equivalent.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and procurement lead times. The RN55D3010FB14 offers higher stock availability for immediate fulfillment.
