Substitute Part Grouping Explanation

Substitution eligibility for the RN55C2002FBSL is determined by the following criteria:

Primary Compatibility Parameters:

• Resistance value: 20 kOhms (exact match required)
• Power rating: 0.125W (1/8W) (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.090" Dia x 0.240" L (exact match required)
• Composition: Metal Film (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Series: RN55 military-grade (exact match required)

Secondary Compatibility Parameters (Allowable Variation):

• Tolerance: ±1% (main part) to ±0.1% (substitute parts) — tighter tolerance is acceptable
• Temperature coefficient: ±50ppm/°C (main part) to ±25ppm/°C (substitute parts) — lower coefficient is acceptable
• Packaging format: Bulk or Cut Tape (CT) — both formats are compatible

Substitute parts are grouped into two categories: upgrade substitutes with improved tolerance specifications and parametric equivalents with matching tolerance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and are manufactured by Vishay Dale under the same military-grade RN55 series specification MIL-R-10509/7. All parts share identical RoHS non-compliance status, REACH affected classification, ECCN EAR99, and HTSUS 8533.21.0090 coding.

RN55C2002BB14 provides direct substitution with improved tolerance (±0.1% versus ±1%) while maintaining identical temperature coefficient and bulk packaging format. This part offers higher inventory availability (1849 units).

RN55E2002BB14 and RN55E2002BRE6 provide substitution with both improved tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C). RN55E2002BRE6 is supplied in Cut Tape format with the highest inventory level (3902 units), while RN55E2002BB14 maintains bulk packaging.

RN55C2002FB14 provides parametric equivalence with matching tolerance (±1%) and temperature coefficient (±50ppm/°C) specifications, offering alternative bulk packaging availability (2338 units).

Frequently Asked Questions (FAQ)

Q: Can RN55C2002BB14 be used as a direct replacement for RN55C2002FBSL?

A: Yes. RN55C2002BB14 is electrically and mechanically compatible. It maintains identical resistance, power rating, package type, physical dimensions, and operating temperature range. The ±0.1% tolerance is tighter than the ±1% specification of the main part, making it suitable for applications where the original tolerance is acceptable.

Q: What is the difference between RN55E2002BB14 and RN55E2002BRE6?

A: Both parts are electrically identical with 20 kOhms ±0.1% resistance and ±25ppm/°C temperature coefficient. The difference is packaging format: RN55E2002BB14 is supplied in Bulk, while RN55E2002BRE6 is supplied in Cut Tape (CT). Selection depends on assembly process requirements and inventory management practices.

Q: Is RN55C2002FB14 equivalent to RN55C2002FBSL?

A: RN55C2002FB14 is a parametric equivalent with matching tolerance (±1%) and temperature coefficient (±50ppm/°C). It provides the same electrical performance specifications and is suitable for direct substitution in applications where the original tolerance and temperature coefficient are required.

Q: Can I substitute a Cut Tape format part for a Bulk format part?

A: Yes, provided all electrical and mechanical parameters match. RN55E2002BRE6 (Cut Tape) can substitute for bulk-packaged equivalents. Packaging format selection is determined by assembly equipment compatibility and supply chain logistics, not electrical performance.

Q: Are all substitute parts compliant with the same military specifications?

A: Yes. All parts are manufactured under MIL-R-10509/7 specification and share identical RoHS non-compliance status, REACH affected classification, and regulatory coding. Military-grade performance and safety features are maintained across all substitute options.
