Substitute Part Grouping Explanation

Substitution eligibility for the RN55D2002FBSL is determined by the following criteria:

Primary Substitution 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)

Secondary Substitution Parameters (Allowable Variations):

• Tolerance: ±1% or tighter (±0.1%)
• Temperature coefficient: ±100ppm/°C or lower (±50ppm/°C or ±25ppm/°C)
• Packaging format: Bulk or Cut Tape (CT)

All substitute parts listed maintain identical electrical performance within the specified operating conditions while offering improved tolerance and temperature stability characteristics or alternative packaging options.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and are manufactured by Vishay Dale within the military-grade RN55 series. Selection between substitute options depends on application-specific requirements:

For applications requiring improved tolerance stability: RN55C2002BB14, RN55E2002BB14, or RN55E2002BRE6 provide ±0.1% tolerance versus the original ±1% specification.

For applications requiring improved temperature coefficient performance: RN55E2002BB14 and RN55E2002BRE6 offer ±25ppm/°C versus the original ±100ppm/°C specification.

For applications with packaging constraints: RN55E2002BRE6 is available in Cut Tape (CT) format, while all other options are supplied in Bulk packaging.

For direct parametric equivalence: RN55D2002FB14 matches the original tolerance and temperature coefficient specifications while offering higher inventory availability (1377 Pcs versus 827 Pcs).

All parts comply with MIL-R-10509/7 military specifications, feature identical physical dimensions, and operate across the full -65°C to 175°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can RN55C2002BB14 be used as a direct replacement for RN55D2002FBSL?

A: Yes. RN55C2002BB14 is electrically compatible as a direct replacement. It maintains identical resistance, power rating, package type, and operating temperature range. The primary difference is improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±50ppm/°C versus ±100ppm/°C), which represent performance enhancements rather than compatibility issues.

Q: What is the difference between RN55E2002BB14 and RN55E2002BRE6?

A: Both parts are electrically identical with 20 kOhms resistance, ±0.1% tolerance, and ±25ppm/°C temperature coefficient. The sole 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 handling procedures.

Q: Is RN55D2002FB14 a suitable alternative to RN55D2002FBSL?

A: Yes. RN55D2002FB14 is a parametric equivalent with identical tolerance (±1%) and temperature coefficient (±100ppm/°C) specifications. Both parts are supplied in Bulk packaging and maintain all military-grade certifications. This part offers higher inventory availability.

Q: Can I use a substitute part with tighter tolerance in a circuit designed for ±1% tolerance?

A: Yes. Parts with tighter tolerance (±0.1%) are fully compatible in applications designed for ±1% tolerance. Tighter tolerance represents improved performance and does not create compatibility issues.

Q: Are all substitute parts RoHS non-compliant like the original?

A: Yes. All listed substitute parts maintain RoHS non-compliant status consistent with the original RN55D2002FBSL specification.
