Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RN55C1003CBSL are qualified based on the following criteria:

Electrical Compatibility:

• Identical resistance value: 100 kOhms
• Equal or superior tolerance specification (±0.1% meets or exceeds ±0.25%)
• Identical power rating: 0.125W (1/8W)
• Identical composition: Metal Film
• Same operating temperature range: -65°C to 175°C
• Same military series classification: MIL-R-10509/7, RN55

Mechanical Compatibility:

• Identical package type: Axial
• Identical physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Identical number of terminations: 2

Compliance & Status:

• Active product status
• Identical RoHS and REACH compliance status
• Same ECCN and HTSUS classifications

Substitute parts RN55C1003BB14 and RN55E1003BRE6 meet all electrical and mechanical requirements. The primary differentiators are tolerance grade (improved to ±0.1%) and packaging format (bulk versus cut tape).

Parameter Comparison

Engineering Selection Recommendations

RN55C1003BB14 is a direct substitute offering improved tolerance specification (±0.1% versus ±0.25%) while maintaining identical electrical and mechanical characteristics. This part is supplied in bulk packaging format and shares the same temperature coefficient performance. Selection is appropriate for applications where tighter tolerance is beneficial and bulk packaging is acceptable.

RN55E1003BRE6 provides the same tolerance improvement (±0.1%) with an additional benefit of reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C), resulting in superior temperature stability. This part is supplied in cut tape packaging format. Selection is appropriate for applications requiring enhanced temperature stability or where cut tape packaging is preferred for automated assembly processes.

Both substitute parts maintain full compliance with military specifications, RoHS/REACH status, and operating temperature range. All three parts are active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RN55C1003BB14 or RN55E1003BRE6 be used as direct replacements for RN55C1003CBSL?

A: Yes. Both substitute parts are electrically and mechanically compatible. They share identical resistance values, power ratings, package types, physical dimensions, and operating temperature ranges. The substitutes offer equal or superior tolerance specifications.

Q: What is the difference between RN55C1003BB14 and RN55E1003BRE6?

A: The primary differences are tolerance grade, temperature coefficient, and packaging format. RN55C1003BB14 maintains ±50ppm/°C temperature coefficient and is supplied in bulk packaging. RN55E1003BRE6 offers improved ±25ppm/°C temperature coefficient and is supplied in cut tape format. Both provide ±0.1% tolerance.

Q: Does packaging format affect electrical performance?

A: No. Bulk and cut tape packaging formats do not affect electrical performance. The selection between formats depends on assembly process requirements and inventory management preferences.

Q: Are all three parts compliant with military specifications?

A: Yes. All three parts conform to MIL-R-10509/7 military specifications and maintain identical RoHS and REACH compliance status.

Q: Which substitute should be selected for temperature-sensitive applications?

A: RN55E1003BRE6 is recommended for applications requiring superior temperature stability due to its ±25ppm/°C temperature coefficient, compared to ±50ppm/°C for the other two parts.
