Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RN55C2001FR36 is determined by the following critical parameters:

Core Electrical Parameters (Non-Negotiable):

• Resistance value: 2 kOhms
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Operating temperature range: -65°C to 175°C
• Package type: Axial

Allowable Variation Parameters:

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

Two substitute parts meet these criteria:

1. RN55E2001BB14 — Upgrade substitute with improved tolerance (±0.1%) and better temperature coefficient (±25ppm/°C), supplied in Bulk packaging
2. RN55C2001FRE6 — Parametric equivalent with identical electrical specifications, supplied in Cut Tape (CT) packaging

Parameter Comparison

Engineering Selection Recommendations

RN55C2001FR36 (Tape & Reel Packaging): Select this part for automated assembly processes requiring reel-based component feeding. Highest current inventory availability supports production schedules.

RN55E2001BB14 (Bulk Packaging, Upgrade Tolerance): Select this part when circuit design specifications require tolerance tighter than ±1% or when improved temperature stability (±25ppm/°C vs. ±50ppm/°C) is necessary. Bulk packaging suits manual assembly or small-batch operations. This part provides enhanced performance characteristics within the same electrical and mechanical envelope.

RN55C2001FRE6 (Cut Tape Packaging, Parametric Equivalent): Select this part when Cut Tape packaging format is required for semi-automated or manual assembly workflows. Electrical specifications are identical to the main part, making it a direct functional replacement with alternative packaging.

All three parts maintain active production status, military-grade specifications, and compliance with MIL-R-10509/7 standards.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 be used as a direct replacement for RN55C2001FR36?

A: Yes. RN55E2001BB14 is electrically and mechanically compatible. It provides improved tolerance (±0.1% vs. ±1%) and better temperature coefficient (±25ppm/°C vs. ±50ppm/°C). The primary difference is packaging format (Bulk vs. Tape & Reel) and enhanced performance characteristics.

Q: What is the difference between RN55C2001FRE6 and RN55C2001FR36?

A: Both parts have identical electrical specifications (2 kOhms ±1%, 0.125W, ±50ppm/°C). The difference is packaging format: RN55C2001FR36 is supplied in Tape & Reel, while RN55C2001FRE6 is supplied in Cut Tape. Selection depends on assembly process requirements.

Q: Are all three parts suitable for military applications?

A: Yes. All three parts are part of the military-grade RN55 series and comply with MIL-R-10509/7 specifications. They feature flame retardant coating, moisture resistance, and safety certifications appropriate for military and high-reliability applications.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel, Bulk, or Cut Tape) does not affect electrical or thermal performance. Selection is based on assembly process compatibility and inventory management requirements.

Q: What is the significance of the temperature coefficient difference between RN55E2001BB14 and the other parts?

A: Temperature coefficient (±25ppm/°C vs. ±50ppm/°C) indicates resistance value stability across temperature variations. RN55E2001BB14 maintains tighter resistance tolerance across the -65°C to 175°C operating range, making it suitable for precision applications requiring enhanced thermal stability.
