Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C2152FBSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 21.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Military specification compliance: MIL-R-10509/7 (exact match required)
• Features: Flame retardant coating, moisture resistance, safety grade (exact match required)

Only parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The RN55C2152FB14 is a direct parametric equivalent to the RN55C2152FBSL. Both parts are manufactured by Vishay Dale, share identical electrical and mechanical specifications, and comply with the same military standard MIL-R-10509/7. Both parts maintain active product status and carry identical regulatory compliance designations (RoHS non-compliant, REACH Affected, ECCN EAR99). Selection between these parts may be based on inventory availability, procurement lead time, or supply chain requirements, as no technical differentiation exists between them.
