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

The identified substitute part RN55D1582FB14 meets all specified electrical and mechanical parameters, confirming direct interchangeability within the RN55 military resistor series.

Parameter Comparison

Engineering Selection Recommendations

Both RN55D1582FBSL and RN55D1582FB14 are active products manufactured by Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. The RN55D1582FB14 offers higher stock availability at 1296 units compared to 661 units for the RN55D1582FBSL. Both components maintain RoHS non-compliant status and REACH Affected classification, with identical ECCN (EAR99) and HTSUS (8533.21.0090) designations. For applications requiring military-grade resistors with flame retardant coating and moisture resistance in the specified temperature range, either part provides equivalent performance and reliability.

Frequently Asked Questions (FAQ)

Q: Are RN55D1582FBSL and RN55D1582FB14 directly interchangeable?

A: Yes. Both parts are identical in resistance value (15.8 kOhms), tolerance (±1%), power rating (0.125W), composition (metal film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 175°C), axial package configuration, and physical dimensions (0.090" Dia × 0.240" L). They are both qualified to MIL-R-10509/7 specifications within the RN55 military series.

Q: What determines substitution eligibility for RN55D1582FBSL?

A: Substitution eligibility requires exact matching across all electrical parameters (resistance, tolerance, power rating, temperature coefficient), composition type (metal film), operating temperature range, package configuration (axial), physical dimensions, and military series compliance (MIL-R-10509/7, RN55).

Q: Can I use a different resistance value or tolerance as a substitute?

A: No. The resistance value of 15.8 kOhms and tolerance of ±1% are critical specifications. Substitutes must match these values exactly to maintain circuit performance and compliance with design specifications.

Q: Are there any compliance differences between the two parts?

A: No. Both RN55D1582FBSL and RN55D1582FB14 share identical RoHS status (non-compliant), REACH status (Affected), ECCN classification (EAR99), and HTSUS code (8533.21.0090).

Q: Which part should I select based on availability?

A: RN55D1582FB14 has higher inventory availability (1296 units) compared to RN55D1582FBSL (661 units). For applications without specific part number requirements, RN55D1582FB14 may offer better supply chain continuity.
