Substitute Part Grouping Explanation

Substitution of the RN55C2003DRSL is permissible with the RN55E2003BB14 based on the following criteria:

Electrical Compatibility: Both parts maintain identical resistance value (200 kOhms) and power rating (0.125W). The substitute part offers improved tolerance (±0.1% versus ±0.5%), which represents an upgrade in precision without affecting circuit functionality.

Mechanical Compatibility: Both parts share identical axial package configuration, physical dimensions (0.090" Dia x 0.240" L), and termination count (2 terminations). This ensures direct mechanical interchangeability in PCB layouts and through-hole applications.

Environmental & Compliance Specifications: Both parts operate across the same temperature range (-65°C to 175°C), feature identical military-grade construction (MIL-R-10509/7, RN55 series), and include flame retardant coating and moisture resistance. Both maintain RoHS non-compliant and REACH Affected status with identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications.

Key Differentiators: The substitute part features improved temperature coefficient (±25ppm/°C versus ±50ppm/°C) and tighter tolerance specification. Packaging differs (Bulk versus Tape & Reel), which may affect procurement and handling but does not impact electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2003DRSL and RN55E2003BB14 are active products manufactured by Vishay Dale within the military-grade RN55 series. Selection between these parts should be based on the following factors:

Tolerance Requirements: Applications requiring tighter tolerance specifications benefit from the RN55E2003BB14 (±0.1% tolerance). The RN55C2003DRSL (±0.5% tolerance) is suitable for applications with standard tolerance requirements.

Temperature Stability: The RN55E2003BB14 provides superior temperature coefficient performance (±25ppm/°C) compared to the RN55C2003DRSL (±50ppm/°C), making it preferable for temperature-sensitive circuits.

Packaging & Procurement: The RN55C2003DRSL is supplied in Tape & Reel (TR) packaging with 1080 pieces in stock. The RN55E2003BB14 is supplied in Bulk packaging with 1440 pieces in stock. Packaging selection depends on assembly process requirements and inventory management practices.

Compliance & Regulatory: Both parts maintain identical RoHS non-compliant and REACH Affected status. No compliance advantage exists between the two options for regulatory purposes.

Frequently Asked Questions (FAQ)

Q: Can RN55E2003BB14 directly replace RN55C2003DRSL in existing designs?

A: Yes. Both parts share identical resistance value (200 kOhms), power rating (0.125W), axial package configuration, and physical dimensions (0.090" Dia x 0.240" L). Direct mechanical and electrical substitution is permissible without PCB layout modifications.

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

A: The RN55E2003BB14 offers tighter tolerance (±0.1% versus ±0.5%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C). Both parts are electrically and mechanically compatible. The RN55E2003BB14 represents a precision upgrade.

Q: Are there packaging differences between these parts?
