RN55C2001CRSL Equivalent & Substitute Parts

Part Overview

The RN55C2001CRSL is a 2 kOhms ±0.25% metal film through-hole resistor rated at 0.125W (1/8W) in axial package configuration. Manufactured by Vishay Dale under the military-grade RN55 series (MIL-R-10509/7), this component features flame retardant coating, moisture resistance, and safety-rated construction suitable for military and high-reliability applications. The part maintains active product status with 740 units in current inventory. Substitute parts are identified when equivalent electrical performance can be achieved within specified tolerance and power rating parameters while maintaining the same physical form factor and environmental operating range.

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C2001CRSL is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 2 kOhms (exact match required)
• Power rating: 0.125W minimum (equal or higher acceptable)
• Package type: Axial (physical form factor must match)
• Operating temperature range: -65°C to 175°C minimum (equal or wider range acceptable)
• Composition: Metal film construction
• Series classification: Military-grade RN55 series

Tolerance Consideration: Substitute parts may have equal or tighter tolerance specifications. The RN55C2001CRSL specifies ±0.25% tolerance. Parts with ±0.1% tolerance or better meet substitution criteria as they provide superior accuracy within the same resistance value and power class.

Temperature Coefficient: Substitute parts with equal or lower temperature coefficient values (±50ppm/°C or better) are acceptable, as they provide equal or improved stability across the operating temperature range.

The RN55E2001BB14 meets all mandatory matching parameters with improved tolerance (±0.1%) and temperature coefficient (±25ppm/°C), qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2001CRSL and RN55E2001BB14 are active products from Vishay Dale within the military-grade RN55 series. Selection between these parts is based on application-specific tolerance and stability requirements:

RN55C2001CRSL Selection Criteria:

• Applications requiring standard ±0.25% tolerance specification
• Cost-sensitive designs where tighter tolerance is not required
• Tape & Reel packaging preference for automated assembly

RN55E2001BB14 Selection Criteria:

• Applications requiring improved accuracy with ±0.1% tolerance
• Circuits sensitive to resistance drift, where lower temperature coefficient (±25ppm/°C) provides performance advantage
• Bulk packaging availability for manual assembly or stock management

Both parts maintain identical electrical performance in terms of resistance value, power rating, and operating temperature range. The RN55E2001BB14 provides superior tolerance and temperature stability characteristics within the same physical form factor and military-grade construction standards.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 directly replace RN55C2001CRSL in existing designs?

A: Yes. Both parts share identical resistance value (2 kOhms), power rating (0.125W), axial package configuration, and operating temperature range (-65°C to 175°C). The RN55E2001BB14 provides tighter tolerance (±0.1% vs ±0.25%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it functionally compatible and performance-superior for direct substitution.

Q: What is the primary difference between these two parts?

A: The RN55E2001BB14 offers improved tolerance specification (±0.1% compared to ±0.25%) and superior temperature stability (±25ppm/°C compared to ±50ppm/°C). Both parts are manufactured by Vishay Dale within the same military RN55 series and maintain identical physical dimensions and power ratings.

Q: Are there packaging differences between these parts?

A: Yes. The RN55C2001CRSL is supplied in Tape & Reel (TR) packaging, while the RN55E2001BB14 is supplied in Bulk packaging. Both use identical axial form factor with dimensions of 0.090" Dia x 0.240" L (2.29mm x 6.10mm). Packaging selection depends on assembly method and inventory management requirements.

Q: Do both parts meet military specifications?

A: Yes. Both the RN55C2001CRSL and RN55E2001BB14 are classified as military-grade components within the RN55 series and comply with MIL-R-10509/7 specifications. Both feature flame retardant coating, moisture resistance, and safety-rated construction.

Q: What compliance status applies to both parts?

A: Both parts are RoHS non-compliant and REACH Affected. Both carry ECCN classification EAR99 and HTSUS code 8533.21.0090. Compliance requirements should be verified against specific application and regional regulations.
