Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C2001FRSL is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2 kOhms
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Package type: Axial
• Physical dimensions: 0.090" Dia × 0.240" L
• Operating temperature range: -65°C to 175°C
• Series compliance: Military, MIL-R-10509/7, RN55

Allowable Variation Parameters:

• Tolerance: ±1% or tighter (±0.1% acceptable)
• Temperature coefficient: ±50ppm/°C or better (±25ppm/°C acceptable)
• Packaging format: Tape & Reel (TR), Bulk, or Cut Tape (CT)

Two substitute parts meet these criteria: RN55E2001BB14 (upgrade tolerance) and RN55C2001FRE6 (parametric equivalent with different packaging).

Parameter Comparison

Engineering Selection Recommendations

RN55C2001FRSL (Tape & Reel Packaging) Select this part for high-volume automated assembly processes requiring tape and reel format. Maintains ±1% tolerance specification and standard temperature coefficient performance within military MIL-R-10509/7 compliance.

RN55E2001BB14 (Bulk Packaging, Upgraded Tolerance) Select this part when tighter tolerance control is required. The ±0.1% tolerance and ±25ppm/°C temperature coefficient provide superior stability compared to the main part. Bulk packaging suits manual assembly or lower-volume applications. All other electrical and mechanical parameters remain equivalent.

RN55C2001FRE6 (Cut Tape Packaging, Parametric Equivalent) Select this part when cut tape format is preferred for semi-automated or manual assembly workflows. Electrical specifications and physical dimensions are identical to the main part. Packaging format is the primary differentiator.

All three parts maintain active production status, military certification, and identical physical form factors suitable for through-hole PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 be used as a direct replacement for RN55C2001FRSL? A: Yes. RN55E2001BB14 is electrically and mechanically compatible. The ±0.1% tolerance is tighter than the ±1% specification of the main part, making it suitable for applications requiring higher precision. The only difference is packaging format (Bulk vs. Tape & Reel).

Q: What is the difference between Tape & Reel, Bulk, and Cut Tape packaging? A: Tape & Reel (TR) format is optimized for automated pick-and-place assembly machines. Bulk packaging consists of loose components suitable for manual assembly or reel loading. Cut Tape (CT) format provides components on carrier tape in smaller quantities, suitable for semi-automated or manual assembly processes.

Q: Are all three parts compliant with the same military standards? A: Yes. All three parts conform to Military series MIL-R-10509/7 and belong to the RN55 product line. They share identical compliance certifications and feature sets.

Q: Can RN55C2001FRE6 replace RN55C2001FRSL in a production assembly? A: Yes. RN55C2001FRE6 is a parametric equivalent with identical electrical and mechanical specifications. The substitution is valid; the primary consideration is packaging format compatibility with your assembly process.

Q: What happens if I use RN55E2001BB14 in a circuit designed for ±1% tolerance? A: RN55E2001BB14 will function correctly. The ±0.1% tolerance is tighter than the ±1% design requirement, so it will not cause circuit malfunction. This represents an upgrade in precision.

Q: Are there any temperature performance differences between these parts? A: RN55E2001BB14 has a superior temperature coefficient (±25ppm/°C vs. ±50ppm/°C), meaning its resistance value remains more stable across temperature variations. Both parts operate across the identical temperature range (-65°C to 175°C).
