Substitute Part Grouping Explanation

The RN55E2003BB14 qualifies as a direct substitute for the RN55C2003FRSL based on the following critical parameters:

• Identical resistance value: 200 kOhms
• Identical power rating: 0.125W (1/8W)
• Identical package configuration: Axial through-hole
• Identical physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Identical operating temperature range: -65°C to 175°C
• Same military series classification: MIL-R-10509/7, RN55
• Identical composition and features: Metal film with flame retardant coating, military grade, moisture resistant, safety certified

The RN55E2003BB14 offers an improved tolerance specification (±0.1% versus ±1%) and a lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring higher precision. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Bulk format.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2003FRSL and RN55E2003BB14 are active production components from Vishay Dale with identical military certification and compliance status. Selection between these parts should be based on application requirements and supply chain considerations:

The RN55C2003FRSL is appropriate for applications where standard ±1% tolerance meets circuit specifications and Tape & Reel packaging is required for automated assembly processes.

The RN55E2003BB14 is appropriate for applications requiring tighter tolerance control (±0.1%) and lower temperature coefficient performance (±25ppm/°C), with Bulk packaging suitable for manual assembly or lower-volume production runs.

Both components maintain identical electrical performance within their respective tolerance bands and are suitable for military and aerospace applications requiring MIL-R-10509/7 compliance.

Frequently Asked Questions (FAQ)

Q: Can RN55E2003BB14 be used as a direct replacement for RN55C2003FRSL in existing designs?

A: Yes. Both components share identical resistance, power rating, package type, dimensions, and operating temperature range. The RN55E2003BB14 offers superior tolerance and temperature coefficient specifications, making it electrically compatible and functionally superior for precision applications.

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

A: The main differences are packaging format (Tape & Reel versus Bulk) and electrical specifications. The RN55E2003BB14 provides ±0.1% tolerance compared to ±1%, and a temperature coefficient of ±25ppm/°C versus ±50ppm/°C.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS non-compliant and REACH Affected status, and both are certified to MIL-R-10509/7 military standards.

Q: Which part should be selected for high-precision analog circuits?

A: The RN55E2003BB14 is the appropriate choice for applications requiring precision analog signal conditioning due to its tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C).

Q: Is packaging format interchangeable between these parts?

A: Packaging format affects supply and assembly processes. Tape & Reel format is optimized for automated pick-and-place assembly, while Bulk format is suitable for manual assembly or lower-volume applications. Electrical performance is identical regardless of packaging format.
