Key Parameters

Substitute Part Grouping Explanation

The RN55C1000BB14 qualifies as a direct substitute based on the following criteria:

Matching parameters: 100 Ohm resistance value, 0.125W power rating, metal film composition, axial package configuration, identical physical dimensions (0.090" Dia x 0.240" L), ±50ppm/°C temperature coefficient, -65°C to 175°C operating range, military series designation (MIL-R-10509/7, RN55), and identical feature set (flame retardant coating, military grade, moisture resistant, safety rated).

Differentiating parameter: Tolerance specification. The RN55C1000BB14 provides ±0.1% tolerance compared to the RN55C1000CBSL's ±0.25% tolerance. This represents an upgrade in precision capability while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C1000CBSL and RN55C1000BB14 are active production components from Vishay Dale with identical military qualification status under MIL-R-10509/7. Selection between these parts depends on tolerance requirements: the RN55C1000CBSL provides ±0.25% tolerance suitable for general military applications, while the RN55C1000BB14 offers ±0.1% tolerance for circuits requiring tighter resistance value control. Both parts maintain identical compliance profiles (RoHS non-compliant, REACH Affected, ECCN EAR99) and are suitable for direct substitution in axial through-hole PCB designs. Inventory availability may influence selection, with 921 units of RN55C1000BB14 currently in stock compared to 704 units of RN55C1000CBSL.

Frequently Asked Questions (FAQ)

Q: Can RN55C1000BB14 replace RN55C1000CBSL in existing designs? A: Yes.
