Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C2002DBSL is determined by the following criteria:

Critical Parameters (Must Match):

• Resistance value: 20 kOhms
• Power rating: 0.125W (1/8W)
• Package type: Axial
• Physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Operating temperature range: -65°C to 175°C
• Composition: Metal Film
• Series compliance: Military, MIL-R-10509/7, RN55

Allowable Variations:

• Tolerance: May be tighter (lower value) than ±0.5%
• Temperature coefficient: May be tighter (lower value) than ±50ppm/°C
• Packaging format: Bulk or Cut Tape (CT)

All identified substitutes maintain identical electrical performance in the 20 kOhms resistance class while offering equal or superior tolerance and temperature stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active production status and are fully compatible with the RN55C2002DBSL in applications requiring 20 kOhms axial metal film resistors. Selection among substitutes should be based on the following factors:

RN55C2002BB14: Direct upgrade offering tighter tolerance (±0.1% vs ±0.5%) while maintaining identical temperature coefficient (±50ppm/°C). Available in Bulk packaging with 1849 units in stock.

RN55E2002BB14: Provides both tighter tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C vs ±50ppm/°C). Available in Bulk packaging with 1118 units in stock. Suitable for applications requiring enhanced stability.

RN55E2002BRE6: Delivers tighter tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C). Available in Cut Tape (CT) packaging format with 3902 units in stock. Optimal for high-volume automated assembly processes.

All parts comply with MIL-R-10509/7 military specifications and maintain identical RoHS and REACH compliance status.

Frequently Asked Questions (FAQ)

Q: Can RN55C2002BB14 be used as a direct replacement for RN55C2002DBSL?

A: Yes. RN55C2002BB14 is electrically and mechanically compatible. It provides superior tolerance (±0.1% vs ±0.5%) while maintaining the same temperature coefficient and all other critical parameters. The only difference is packaging format (Bulk).

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 primary difference is packaging format: RN55E2002BB14 is supplied in Bulk, while RN55E2002BRE6 is supplied in Cut Tape (CT) format suitable for automated pick-and-place assembly.

Q: Are all substitute parts military-grade?

A: Yes. All substitute parts are part of the military RN55 series and comply with MIL-R-10509/7 specifications, featuring flame retardant coating and moisture resistance.

Q: Can I use a substitute with tighter tolerance in place of the original part?

A: Yes. Tighter tolerance (lower percentage value) is a compatible upgrade. Parts with ±0.1% tolerance can be used in any application designed for ±0.5% tolerance without circuit redesign.

Q: What is the difference between Bulk and Cut Tape (CT) packaging?

A: Bulk packaging is suitable for manual assembly and small-quantity applications. Cut Tape (CT) packaging is formatted for automated pick-and-place assembly equipment in high-volume production environments.

Q: Do all parts have the same physical dimensions?

A: Yes. All parts maintain identical axial package dimensions of 0.090" Dia x 0.240" L (2.29mm x 6.10mm), ensuring mechanical compatibility in PCB layouts.
