Parameter Comparison

Engineering Selection Recommendations

The RN55E2003BB14 is a direct electrical and mechanical substitute for the RN55C2003CRSL. Both components maintain active product status and comply with identical military specifications (MIL-R-10509/7). The RN55E2003BB14 provides improved performance characteristics with tighter tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring enhanced precision and thermal stability. Both parts are RoHS non-compliant and REACH Affected with identical ECCN (EAR99) and HTSUS classifications. Selection between these parts depends on packaging requirements: Tape & Reel format for automated assembly versus Bulk format for manual or alternative handling processes.

Frequently Asked Questions (FAQ)

Q: Can RN55E2003BB14 be used as a direct replacement for RN55C2003CRSL in existing designs?

A: Yes. Both components share identical electrical specifications (200 kOhms, 0.125W), mechanical dimensions (0.090" Dia x 0.240" L), package type (Axial), and operating temperature range (-65°C to 175°C). The RN55E2003BB14 offers improved tolerance and temperature coefficient performance.

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

A: The RN55E2003BB14 provides tighter tolerance (±0.1% versus ±0.25%) and superior temperature coefficient (±25ppm/°C versus ±50ppm/°C). Additionally, packaging differs: RN55C2003CRSL is supplied in Tape & Reel format while RN55E2003BB14 is supplied in Bulk format.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical compliance status. Both are RoHS non-compliant, REACH Affected, and classified under ECCN EAR99 with HTSUS code 8533.21.0090. Both comply with military specification MIL-R-10509/7.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel versus Bulk) affects only handling, storage, and assembly processes. Electrical and mechanical performance remain identical regardless of packaging format.

Q: Which part should be selected for precision-critical applications?

A: The RN55E2003BB14 is suitable for applications requiring enhanced precision due to its tighter tolerance specification (±0.1%) and lower temperature coefficient (±25ppm/°C).
