Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN55C2001CRE6 is permissible when the following core electrical and mechanical parameters remain within specification:

• Resistance value: 2 kOhms (exact match required)
• Power rating: 0.125W minimum (1/8W or higher acceptable)
• Package type: Axial through-hole configuration
• Operating temperature range: -65°C to 175°C minimum coverage
• Composition: Metal film construction
• Series compliance: Military-grade RN55 series (MIL-R-10509/7)

The RN55E2001BB14 qualifies as a direct substitute based on these parameters. Tolerance and temperature coefficient may vary within the allowed electrical specifications for the component category, provided the substitute meets or exceeds the performance requirements of the original design.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2001CRE6 and RN55E2001BB14 maintain active product status from Vishay Dale and comply with military-grade specifications under MIL-R-10509/7. The RN55E2001BB14 offers improved tolerance performance (±0.1% versus ±0.25%) and superior temperature coefficient stability (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring tighter component matching or enhanced thermal stability. Selection between these parts depends on packaging requirements (Tape & Reel versus Bulk) and tolerance specifications demanded by the circuit design. Both parts are RoHS non-compliant and REACH Affected, with identical compliance certifications (ECCN: EAR99, HTSUS: 8533.21.0090).

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 directly replace RN55C2001CRE6 in existing designs?

A: Yes. Both components share identical resistance value (2 kOhms), power rating (0.125W), operating temperature range (-65°C to 175°C), physical dimensions (0.090" Dia x 0.240" L), and axial package configuration. The substitute features superior tolerance (±0.1%) and temperature coefficient (±25ppm/°C), making it functionally compatible and performance-equivalent.

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

A: The RN55E2001BB14 provides tighter tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). Packaging differs: RN55C2001CRE6 is supplied in Tape & Reel format, while RN55E2001BB14 is supplied in Bulk format.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS status (non-compliant), REACH status (Affected), ECCN classification (EAR99), and HTSUS code (8533.21.0090). Military-grade specifications and certifications are equivalent.

Q: Does packaging format affect electrical performance?

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

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

A: The RN55E2001BB14 is appropriate for applications requiring tighter tolerance control and improved temperature stability due to its ±0.1% tolerance and ±25ppm/°C temperature coefficient specifications.
