Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C2001DRE6 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2 kOhms
• Power rating: 0.125W (1/8W)
• Package type: Axial
• Composition: Metal Film
• Operating temperature range: -65°C to 175°C
• Series compliance: Military, MIL-R-10509/7, RN55

Allowable Variation Parameters:

• Tolerance: May be equal to or tighter (lower) than ±0.5%
• Temperature coefficient: May be equal to or lower than ±50ppm/°C
• Packaging format: May differ (Tape & Reel to Bulk or equivalent)

The RN55E2001BB14 qualifies as a direct substitute by maintaining all mandatory parameters while offering improved tolerance (±0.1% versus ±0.5%) and superior temperature coefficient (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both RN55C2001DRE6 and RN55E2001BB14 maintain active product status from Vishay Dale and comply with military specification MIL-R-10509/7. Selection between these parts should be based on application-specific requirements:

The RN55C2001DRE6 is appropriate for applications where standard ±0.5% tolerance and ±50ppm/°C temperature coefficient meet circuit design specifications and where Tape & Reel packaging format is required for automated assembly processes.

The RN55E2001BB14 provides enhanced performance characteristics with tighter ±0.1% tolerance and improved ±25ppm/°C temperature coefficient, suitable for precision circuits requiring superior stability across the full operating temperature range. Bulk packaging format may require manual handling or alternative assembly accommodation.

Both parts share identical electrical ratings, mechanical dimensions, and military-grade construction features. RoHS non-compliance status is consistent across both variants. REACH and ECCN classifications remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 directly replace RN55C2001DRE6 in existing designs?

A: Yes. Both parts maintain identical resistance value (2 kOhms), power rating (0.125W), operating temperature range (-65°C to 175°C), and axial package configuration. The substitute offers improved tolerance and temperature coefficient specifications, which are compatible with any circuit designed for the original part.

Q: What is the significance of tolerance difference between ±0.5% and ±0.1%?

A: Tolerance defines the maximum deviation from the nominal 2 kOhm resistance value. The RN55C2001DRE6 allows ±100 ohms deviation (1900-2100 ohms), while RN55E2001BB14 restricts deviation to ±20 ohms (1980-2020 ohms). Tighter tolerance is beneficial for precision analog circuits, filters, and measurement applications but is not required for general-purpose applications.

Q: Does packaging format (Tape & Reel versus Bulk) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly methodology. Electrical and mechanical specifications remain identical. Tape & Reel format suits automated pick-and-place assembly, while Bulk format requires manual component handling.

Q: Are both parts suitable for military applications?

A: Yes. Both RN55C2001DRE6 and RN55E2001BB14 comply with military specification MIL-R-10509/7 and feature military-grade construction including flame retardant coating and moisture resistance. Both maintain active product status.

Q: What is the temperature coefficient significance?

A: Temperature coefficient (±50ppm/°C versus ±25ppm/°C) indicates resistance value drift across the operating temperature range. Lower temperature coefficient means more stable resistance performance across temperature extremes. For circuits operating across the full -65°C to 175°C range, the RN55E2001BB14 provides superior stability.
