Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RN55E2002DR36 are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain the same resistance value (20 kOhms), power rating (0.125W), temperature coefficient (±25ppm/°C), and operating temperature range (-65°C to 175°C). These parameters are non-negotiable for direct substitution.

Mechanical Compatibility: All substitute parts share identical physical dimensions (0.090" Dia × 0.240" L), axial package configuration, and two-termination design, ensuring mechanical interchangeability in circuit board layouts.

Material & Construction: All parts use metal film composition with flame retardant coating, military-grade construction, and moisture resistance, maintaining the same safety and reliability characteristics.

Tolerance Variance: The RN55E2002DR36 specifies ±0.5% tolerance. Substitute parts RN55E2002BB14 and RN55E2002BRE6 offer ±0.1% tolerance, representing an upgrade in precision while remaining electrically compatible for applications where tighter tolerance is acceptable or beneficial.

Packaging Differences: Substitutes vary in packaging format (Tape & Reel, Bulk, Cut Tape) to accommodate different procurement and assembly workflows without affecting component performance.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RN55E2002DR36, RN55E2002BB14, and RN55E2002BRE6—are active products from Vishay Dale with identical electrical and mechanical specifications. Selection between them is determined by packaging requirements and tolerance specifications:

RN55E2002DR36 is the baseline specification with ±0.5% tolerance in Tape & Reel packaging, suitable for high-volume automated assembly operations.

RN55E2002BB14 provides ±0.1% tolerance in Bulk packaging, appropriate for applications requiring tighter tolerance control or manual assembly workflows.

RN55E2002BRE6 offers ±0.1% tolerance in Cut Tape packaging, suitable for mixed-volume production or applications requiring precision tolerance with flexible packaging options.

All parts maintain identical compliance status (RoHS non-compliant, REACH Affected, ECCN EAR99, HTSUS 8533.21.0090) and are suitable for military-grade applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RN55E2002BB14 or RN55E2002BRE6 be used as direct replacements for RN55E2002DR36?

A: Yes. Both substitute parts maintain identical resistance, power rating, temperature coefficient, operating temperature range, physical dimensions, and axial package configuration. The ±0.1% tolerance of the substitutes is tighter than the ±0.5% specification of the original part, making them electrically and mechanically compatible for direct substitution.

Q: What is the difference between the three packaging formats?

A: RN55E2002DR36 is supplied in Tape & Reel format for automated pick-and-place assembly. RN55E2002BB14 is supplied in Bulk format for manual assembly or custom packaging. RN55E2002BRE6 is supplied in Cut Tape format for semi-automated or mixed-volume assembly. All three formats contain identical components with no functional differences.

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), ECCN classification (EAR99), and HTSUS code (8533.21.0090). They are all military-grade components from the same MIL-R-10509/7 RN55 series.

Q: Does the tighter tolerance of the substitute parts affect circuit performance?

A: The ±0.1% tolerance of RN55E2002BB14 and RN55E2002BRE6 is a refinement of the ±0.5% specification. Tighter tolerance does not degrade performance and may improve circuit accuracy in applications sensitive to resistor value variation. Both are electrically compatible with designs specified for ±0.5% tolerance.

Q: Can these parts be used interchangeably in military applications?

A: Yes. All three parts are military-grade components from the MIL-R-10509/7 RN55 series with identical flame retardant coating, moisture resistance, and safety features. They are suitable for military applications within the specified operating temperature range of -65°C to 175°C.
