Substitute Part Grouping Explanation

Substitution of RN55C1001BRSL is determined by strict equivalence in the following critical parameters: resistance value (1 kOhms), tolerance (±0.1%), power rating (0.125W), composition (metal film), package type (axial), operating temperature range (-65°C to 175°C), and military series compliance (MIL-R-10509/7, RN55). All identified substitutes maintain these core electrical and mechanical specifications. Variations in packaging format (Tape & Reel, Cut Tape, or Bulk) and temperature coefficient do not affect functional equivalence for standard circuit applications. The substitute parts RN55E1001BB14, RN55E1001BRE6, and RN55C1001BRE6 satisfy all substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active product status and identical compliance profiles (RoHS non-compliant, REACH Affected, ECCN EAR99, HTSUS 8533.21.0090). Selection between RN55C1001BRSL and its substitutes should be based on packaging requirements and inventory availability. RN55C1001BRE6 offers the highest inventory level (4078 pieces) with identical temperature coefficient specification to the main part. RN55E1001BB14 and RN55E1001BRE6 feature improved temperature coefficient performance (±25ppm/°C versus ±50ppm/°C), which may provide enhanced stability in temperature-sensitive applications, though this represents a performance upgrade rather than a direct equivalent. Packaging format selection (Tape & Reel, Cut Tape, or Bulk) depends on assembly process requirements and procurement volume.

Frequently Asked Questions (FAQ)

Q: Can RN55E1001BB14 be used as a direct replacement for RN55C1001BRSL? A: Yes. Both parts share identical electrical specifications (1 kOhms, ±0.1%, 0.125W, metal film, axial package, -65°C to 175°C operating range, military MIL-R-10509/7 compliance). The difference in packaging format (Bulk versus Tape & Reel) does not affect functional compatibility. The improved temperature coefficient (±25ppm/°C) represents a performance enhancement.

Q: What is the difference between RN55C1001BRE6 and RN55E1001BRE6? A: Both parts are supplied in Cut Tape (CT) packaging with identical electrical specifications. The primary difference is temperature coefficient: RN55C1001BRE6 maintains ±50ppm/°C (matching the main part), while RN55E1001BRE6 offers ±25ppm/°C. Both are functionally equivalent for standard applications.

Q: Does packaging format affect circuit performance? A: No. Tape & Reel (TR), Cut Tape (CT), and Bulk packaging formats are assembly and procurement considerations only. They do not alter electrical performance or mechanical fit in axial through-hole applications.

Q: Are all substitutes military-grade components? A: Yes. All four parts comply with military specifications (MIL-R-10509/7) and are part of the RN55 military series with identical feature sets (flame retardant coating, moisture resistance, safety classification).

Q: Which substitute offers the best inventory availability? A: RN55C1001BRE6 has the highest stock level at 4078 pieces, followed by RN55E1001BB14 at 1881 pieces and RN55E1001BRE6 at 1091 pieces.
