Substitute Part Grouping Explanation

The RN55E2003BB14 qualifies as a direct substitute for the RN55C2003DR36 based on the following critical parameters:

• Resistance Value: Both parts are 200 kOhms
• Power Rating: Both rated at 0.125W (1/8W)
• Composition: Both are metal film construction
• Package Type: Both use axial through-hole configuration
• Physical Dimensions: Identical at 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Operating Temperature Range: Both operate from -65°C to 175°C
• Series Classification: Both belong to the military RN55 series (MIL-R-10509/7)
• Features: Both include flame retardant coating, military grade, moisture resistance, and safety certification

The RN55E2003BB14 provides improved tolerance (±0.1% versus ±0.5%) and superior temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring tighter component specifications. The primary difference is packaging format: RN55C2003DR36 is supplied in tape & reel, while RN55E2003BB14 is supplied in bulk.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2003DR36 and RN55E2003BB14 are active production components from Vishay Dale with identical military-grade specifications and certifications. Selection between these parts should be based on the following criteria:

RN55C2003DR36 is appropriate when tape & reel packaging is required for automated assembly processes or when standard tolerance of ±0.5% meets circuit specifications.

RN55E2003BB14 is appropriate when tighter tolerance control (±0.1%) and improved temperature stability (±25ppm/°C) are required for precision circuit applications, or when bulk packaging is acceptable for manual assembly or stock management.

Both parts maintain identical electrical performance within their respective tolerance bands across the full operating temperature range of -65°C to 175°C. Neither part is RoHS compliant, and both are subject to REACH regulations. Component selection should account for procurement lead times, packaging requirements, and circuit tolerance budgets.

Frequently Asked Questions (FAQ)

Q: Can RN55E2003BB14 be used as a direct replacement for RN55C2003DR36 in existing designs?

A: Yes. Both parts share identical resistance value, power rating, physical dimensions, and operating temperature range. The RN55E2003BB14 provides superior tolerance and temperature coefficient specifications, making it electrically compatible and functionally superior for the same circuit application.

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

A: The main differences are packaging format (tape & reel versus bulk) and electrical specifications. RN55E2003BB14 offers ±0.1% tolerance compared to ±0.5%, and ±25ppm/°C temperature coefficient compared to ±50ppm/°C. Both are military-grade metal film resistors from the same RN55 series.

Q: Are there any compatibility concerns with PCB assembly equipment?

A: No. Both parts use identical axial through-hole package configuration with the same physical dimensions (0.090" Dia x 0.240" L). They are mechanically and electrically interchangeable on PCBs designed for axial resistor mounting. Packaging format differences (tape & reel versus bulk) affect only the supply and handling method, not board-level compatibility.

Q: Do these parts meet military specifications?

A: Yes. Both RN55C2003DR36 and RN55E2003BB14 are classified as military-grade components under the MIL-R-10509/7 standard and belong to the Vishay Dale RN55 series. Both include flame retardant coating, moisture resistance, and safety features required for military applications.

Q: What is the impact of tolerance differences on circuit performance?

A: The RN55C2003DR36 has ±0.5% tolerance, meaning the actual resistance value can range from 199 kOhms to 201 kOhms. The RN55E2003BB14 has ±0.1% tolerance, with actual values ranging from 199.8 kOhms to 200.2 kOhms. Selection depends on circuit sensitivity to resistance variation and whether the tighter tolerance of RN55E2003BB14 is necessary for design specifications.
