Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RN55E2002FRSL are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 20 kOhms
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -65°C to 175°C
• Series classification: Military, MIL-R-10509/7, RN55

Mechanical Parameters (Must Match):

• Package type: Axial
• Physical dimensions: 0.090" Dia × 0.240" L (2.29mm × 6.10mm)
• Number of terminations: 2

Allowable Variations:

• Tolerance: ±1% (main part) to ±0.1% (substitute parts) — tighter tolerance is acceptable
• Packaging format: Tape & Reel (TR), Bulk, or Cut Tape (CT) — different packaging does not affect electrical or mechanical compatibility

The identified substitutes RN55E2002BB14 and RN55E2002BRE6 meet all mandatory electrical and mechanical criteria. Both offer improved tolerance (±0.1%) compared to the main part (±1%), making them suitable upgrades for applications requiring higher precision.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and identical compliance classifications (RoHS non-compliant, REACH Affected). Selection between the main part and substitutes depends on packaging requirements and tolerance specifications:

RN55E2002FRSL (Main Part): Select when Tape & Reel packaging is required for automated assembly processes and ±1% tolerance meets circuit specifications.

RN55E2002BB14 (Substitute): Select when Bulk packaging is acceptable and ±0.1% tolerance is required for precision applications. Higher inventory availability (1118 pcs) supports larger production runs.

RN55E2002BRE6 (Substitute): Select when Cut Tape packaging is required and ±0.1% tolerance is required. Highest inventory availability (3902 pcs) supports extended supply chain requirements.

All parts are manufactured by Vishay Dale under the military MIL-R-10509/7 specification and are electrically and mechanically interchangeable within their respective packaging formats.

Frequently Asked Questions (FAQ)

Q: Can RN55E2002BB14 or RN55E2002BRE6 be used as direct replacements for RN55E2002FRSL?

A: Yes. Both substitute parts are electrically and mechanically identical to the main part. They share the same resistance value (20 kOhms), power rating (0.125W), composition (metal film), temperature coefficient (±25ppm/°C), operating temperature range (-65°C to 175°C), and physical dimensions (0.090" Dia × 0.240" L). The only differences are packaging format and tolerance specification. The tighter tolerance (±0.1%) of the substitutes is compatible with any application accepting the main part's ±1% tolerance.

Q: What is the difference between Tape & Reel, Bulk, and Cut Tape packaging?

A: Tape & Reel (TR) packaging is used for automated pick-and-place assembly and is supplied on continuous carrier tape. Bulk packaging consists of loose components suitable for manual assembly or reel loading. Cut Tape (CT) packaging provides components on tape segments, offering a middle ground between automated and manual assembly. All three formats contain identical components; packaging selection depends on assembly process requirements.

Q: Are the substitute parts suitable for military applications?

A: Yes. All three parts are classified as military-grade components within the RN55 series and comply with MIL-R-10509/7 specification. They feature flame retardant coating, moisture resistance, and safety certification appropriate for military and aerospace applications.

Q: What does the tolerance difference (±1% vs ±0.1%) mean for circuit performance?

A: Tolerance specifies the maximum deviation of the actual resistance value from the nominal 20 kOhms specification. The main part (±1%) allows actual values between 19.8 kOhms and 20.2 kOhms. The substitute parts (±0.1%) allow actual values between 19.98 kOhms and 20.02 kOhms. Tighter tolerance is beneficial for precision analog circuits, measurement equipment, and applications with strict impedance matching requirements. For general-purpose applications, both tolerances are functionally equivalent.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. The identical axial package type and physical dimensions (0.090" Dia × 0.240" L) ensure mechanical compatibility with existing PCB layouts and through-hole footprints. No design modifications are required when substituting between these parts.
