Substitute Part Grouping Explanation

Substitute parts for the RN55C2002CBSL are qualified based on the following criteria:

Core Matching Parameters (Non-Negotiable):

Resistance value: 20 kOhms
Power rating: 0.125W (1/8W)
Package type: Axial
Operating temperature range: -65°C to 175°C

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the RN55C2002CBSL and maintain active product status with consistent military-grade specifications. Selection among these parts should be based on the following factors:

Tolerance Requirements: RN55C2002BB14, RN55E2002BB14, and RN55E2002BRE6 all offer improved tolerance of ±0.1% compared to the main part's ±0.25%, making them suitable for applications requiring tighter resistance accuracy.

Temperature Stability: RN55E2002BB14 and RN55E2002BRE6 feature a temperature coefficient of ±25ppm/°C, providing superior thermal stability compared to the main part and RN55C2002BB14 at ±50ppm/°C. This enhancement is beneficial for temperature-sensitive circuit applications.

Packaging Format: RN55C2002BB14 and RN55E2002BB14 are supplied in Bulk packaging, while RN55E2002BRE6 is supplied in Cut Tape (CT) format. Packaging selection depends on assembly process requirements and inventory management practices.

Compliance and Regulatory Status: All parts maintain identical RoHS non-compliant and REACH Affected status, ensuring consistent regulatory treatment across substitutions.

Availability: RN55E2002BRE6 offers the highest inventory level at 3902 pieces, followed by RN55C2002BB14 at 1849 pieces and RN55E2002BB14 at 1118 pieces.

Frequently Asked Questions (FAQ)

Q: Can RN55C2002BB14 be used as a direct replacement for RN55C2002CBSL?

A: Yes. RN55C2002BB14 is a direct functional equivalent. Both parts share identical resistance (20 kOhms), power rating (0.125W), package type (Axial), operating temperature range (-65°C to 175°C), and series designation (RN55). The substitute offers improved tolerance (±0.1% vs. ±0.25%) and maintains the same temperature coefficient (±50ppm/°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, while RN55E2002BRE6 is supplied in Cut Tape (CT). The Cut Tape format is typically used for automated assembly processes, while Bulk packaging is used for manual assembly or reel-based operations.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All parts maintain identical RoHS non-compliant and REACH Affected status. Regulatory treatment remains consistent across all qualified substitutes.

Q: Which substitute offers the best temperature stability?

A: RN55E2002BB14 and RN55E2002BRE6 both feature a temperature coefficient of ±25ppm/°C, providing superior thermal stability compared to RN55C2002CBSL and RN55C2002BB14, which are rated at ±50ppm/°C.

Q: Can I mix packaging formats in the same assembly?

A: Yes. RN55E2002BRE6 (Cut Tape) and RN55C2002BB14 or RN55E2002BB14 (Bulk) are mechanically and electrically identical and can be used interchangeably. Packaging format selection should align with your assembly process capabilities and inventory management requirements.

Q: What is the physical size of these resistors?

A: All parts share identical dimensions: 0.090" diameter × 0.240" length (2.29mm × 6.10mm) in axial configuration.
