Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RN55C2002CB14 is determined by the following criteria:

Core Electrical Parameters (Non-Negotiable):

• 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)

Allowable Variations:

• Tolerance: ±0.25% or tighter (±0.1% acceptable as upgrade)
• Temperature coefficient: ±50ppm/°C or ±25ppm/°C (tighter coefficient acceptable)
• Packaging format: Bulk or Cut Tape (CT) (both compatible for through-hole assembly)

Compliance & Series:

• Military series designation (RN55, MIL-R-10509/7) maintained across all substitutes
• RoHS and REACH status consistent with original part

All identified substitutes maintain identical electrical performance within the specified operating temperature range and meet or exceed the original part's tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are direct functional equivalents to RN55C2002CB14 and are suitable for replacement in applications requiring 20 kOhms ±0.25% metal film axial resistors.

RN55C2002BB14: Offers improved tolerance specification (±0.1% versus ±0.25%) while maintaining identical temperature coefficient and operating range. Maintains Bulk packaging format. Recommended for applications where tighter tolerance is beneficial and packaging format consistency is required.

RN55E2002BB14: Provides both improved tolerance (±0.1%) and superior temperature coefficient (±25ppm/°C versus ±50ppm/°C). Maintains Bulk packaging format. Recommended for precision applications requiring enhanced temperature stability.

RN55E2002BRE6: Delivers identical electrical performance to RN55E2002BB14 with improved temperature coefficient (±25ppm/°C) and tighter tolerance (±0.1%). Supplied in Cut Tape (CT) packaging format. Recommended for high-volume automated assembly processes where tape packaging is preferred.

All parts maintain active production status, military series compliance, and identical RoHS/REACH regulatory status. Selection between substitutes should be based on tolerance requirements, temperature stability needs, and packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RN55C2002BB14 be used as a direct replacement for RN55C2002CB14?

A: Yes. RN55C2002BB14 is a direct functional equivalent. Both parts share identical resistance (20 kOhms), power rating (0.125W), composition (metal film), package type (axial), and physical dimensions. RN55C2002BB14 offers improved tolerance (±0.1% versus ±0.25%) and maintains the same temperature coefficient (±50ppm/°C) and operating range (-65°C to 175°C).

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 packaging, while RN55E2002BRE6 is supplied in Cut Tape (CT) packaging. Selection depends on assembly process requirements.

Q: Are all substitute parts compatible with the original circuit design?

A: Yes. All substitute parts maintain identical electrical specifications (resistance, power rating, composition) and mechanical compatibility (axial package, physical dimensions). They operate within the same temperature range (-65°C to 175°C) and are suitable for direct board-level replacement without circuit modification.

Q: What does the tolerance specification mean for part selection?

A: Tolerance specifies the maximum allowable deviation from the nominal 20 kOhms resistance value. RN55C2002CB14 allows ±0.25% deviation (19.95 kOhms to 20.05 kOhms), while substitute parts with ±0.1% tolerance (RN55C2002BB14, RN55E2002BB14, RN55E2002BRE6) allow tighter deviation (19.98 kOhms to 20.02 kOhms). Tighter tolerance is beneficial in precision circuits but not required for general applications.

Q: Does temperature coefficient affect part selection?

A: Temperature coefficient indicates resistance change over the operating temperature range. RN55C2002CB14 and RN55C2002BB14 have ±50ppm/°C, while RN55E2002BB14 and RN55E2002BRE6 have ±25ppm/°C. The tighter coefficient in E-series parts provides better stability across temperature extremes, beneficial for precision analog circuits or wide temperature range applications.

Q: Can Cut Tape (CT) packaged parts replace Bulk packaged parts?

A: Yes, from an electrical and mechanical standpoint. RN55E2002BRE6 (Cut Tape) is functionally equivalent to Bulk-packaged alternatives. Selection depends on assembly process compatibility. Bulk packaging suits manual or small-batch assembly, while Cut Tape suits automated pick-and-place equipment.
