Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RN55D2003FRSL are classified based on the following allowed parameters:

Parametric Equivalent (RN55D2003FRE6): Identical electrical specifications (200 kOhms, ±1% tolerance, 0.125W power rating, ±100ppm/°C temperature coefficient) and mechanical dimensions. Differs only in packaging format (Cut Tape instead of Tape & Reel), making it suitable for applications where tape format is interchangeable.

Upgrade Substitute (RN55E2003BB14): Maintains identical resistance value (200 kOhms), power rating (0.125W), operating temperature range (-65°C to 175°C), and physical dimensions. Provides improved tolerance specification (±0.1% versus ±1%) and superior temperature coefficient (±25ppm/°C versus ±100ppm/°C). Packaged in Bulk format. This part represents an electrical upgrade while maintaining mechanical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

RN55D2003FRE6 Selection: Choose this parametric equivalent when Cut Tape packaging is compatible with assembly processes. Electrical performance is identical to the main part. All military certifications, compliance status, and thermal characteristics remain unchanged.

RN55E2003BB14 Selection: Select this upgrade substitute when improved tolerance (±0.1%) and temperature stability (±25ppm/°C) are required for precision circuit applications. Bulk packaging format must be compatible with procurement and assembly workflows. All military specifications and operating parameters remain qualified.

RN55D2003FRSL Retention: Maintain the original part specification when Tape & Reel packaging is mandated by assembly equipment or when the ±1% tolerance and ±100ppm/°C temperature coefficient meet circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can RN55D2003FRE6 be used as a direct replacement for RN55D2003FRSL?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (200 kOhms, ±1%, 0.125W, ±100ppm/°C) and mechanical dimensions. The only difference is packaging format (Cut Tape versus Tape & Reel). Compatibility depends on whether your assembly process accepts Cut Tape format.

Q: What is the primary advantage of RN55E2003BB14?

A: RN55E2003BB14 provides tighter tolerance (±0.1% versus ±1%) and superior temperature stability (±25ppm/°C versus ±100ppm/°C). These improvements benefit precision analog circuits, measurement instrumentation, and applications requiring stable reference resistances across temperature ranges.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical physical dimensions (0.090" Dia × 0.240" L) and axial package configuration, enabling direct mechanical substitution on PCBs. Packaging format differences (Tape & Reel, Cut Tape, Bulk) affect only procurement and assembly handling, not board-level installation.

Q: Do substitute parts maintain military compliance?

A: Yes. All substitute parts are manufactured by Vishay Dale within the RN55 military series, comply with MIL-R-10509/7, and carry identical certifications for flame retardant coating, moisture resistance, and safety features. RoHS and REACH compliance status remains consistent across all three parts.

Q: Which part should be selected for high-temperature applications?

A: All three parts operate across the identical temperature range (-65°C to 175°C). Selection should be based on tolerance and temperature coefficient requirements. RN55E2003BB14 offers superior temperature coefficient stability (±25ppm/°C) for applications requiring minimal resistance drift across temperature extremes.
