Substitute Part Grouping Explanation

Substitution eligibility for the RN55E2002FRE6 is determined by the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 20 kOhms (exact match required)
• Power rating: 0.125W (1/8W) (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.090" Dia x 0.240" L (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Series compliance: MIL-R-10509/7, RN55 (exact match required)

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±1% or better)
• Packaging format: May differ (Tape & Reel, Cut Tape, or Bulk)

The substitute parts RN55E2002BB14 and RN55E2002BRE6 meet all mandatory compatibility requirements. Both offer improved tolerance specification (±0.1% versus ±1%), representing an upgrade in precision while maintaining all other electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and identical compliance certifications (RoHS non-compliant, REACH Affected, ECCN EAR99). Selection between RN55E2002FRE6 and its substitutes should be based on packaging requirements and tolerance specifications:

RN55E2002FRE6 (Tape & Reel): Select when automated assembly processes require tape and reel packaging format and ±1% tolerance specification is acceptable for the application.

RN55E2002BB14 (Bulk): Select when bulk packaging is preferred and improved ±0.1% tolerance specification is required. Suitable for manual assembly or applications demanding tighter resistance tolerance.

RN55E2002BRE6 (Cut Tape): Select when cut tape packaging is required and improved ±0.1% tolerance specification is required. Offers highest inventory availability (3902 units) and represents the optimal choice for applications requiring precision tolerance with flexible packaging options.

Frequently Asked Questions (FAQ)

Q: Can RN55E2002BB14 or RN55E2002BRE6 be used as direct replacements for RN55E2002FRE6?

A: Yes. Both substitute parts are electrically and mechanically identical to the RN55E2002FRE6, with the exception of packaging format and improved tolerance specification. The ±0.1% tolerance of the substitutes is tighter than the ±1% specification of the original part, making them suitable for any application accepting the original part.

Q: What is the primary difference between the three parts?

A: The primary differences are packaging format (Tape & Reel, Bulk, or Cut Tape) and tolerance specification (±1% versus ±0.1%). All other electrical and mechanical parameters are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts share identical RoHS status (non-compliant), REACH status (Affected), and ECCN classification (EAR99). They are all part of the same military-grade RN55 series compliant with MIL-R-10509/7.

Q: Which substitute part should be selected for new designs?

A: Selection depends on assembly process requirements and tolerance specifications. For automated assembly, RN55E2002FRE6 (Tape & Reel) is standard. For applications requiring improved tolerance, RN55E2002BRE6 (Cut Tape) offers the best combination of precision and packaging flexibility with highest inventory availability.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, provided the assembly process can accommodate the different packaging format. The electrical performance and physical dimensions are identical across all three parts.
