Substitute Part Grouping Explanation

Substitution eligibility for the RN55E1002CBSL is determined by the following criteria:

Electrical Compatibility Requirements:

• Resistance value must equal 10 kOhms
• Tolerance must be equal to or tighter than ±0.25%
• Power rating must be equal to or greater than 0.125W
• Temperature coefficient must be ±25ppm/°C or better
• Operating temperature range must encompass -65°C to 175°C

Mechanical Compatibility Requirements:

• Package type must be Axial
• Physical dimensions must match 0.090" Dia × 0.240" L
• Number of terminations must be 2

Compliance Requirements:

• Series designation must align with Military, MIL-R-10509/7, RN55
• Product status must be Active
• Composition must be Metal Film

Both identified substitutes meet all electrical, mechanical, and compliance criteria. The primary distinction between substitutes is packaging format (Bulk versus Cut Tape) and tolerance specification improvement (±0.1% versus ±0.25%).

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain Active product status and comply with identical military specifications and certifications as the main part. Selection between RN55E1002CBSL and its substitutes should be based on the following factors:

Tolerance Requirements: If circuit design requires tolerance tighter than ±0.25%, both RN55E1002BB14 and RN55E1002BRE6 provide ±0.1% tolerance while maintaining all other electrical and mechanical parameters.

Packaging Requirements: RN55E1002BB14 is supplied in Bulk packaging, matching the main part format. RN55E1002BRE6 is supplied in Cut Tape (CT) format, suitable for automated assembly processes.

Inventory Availability: RN55E1002BRE6 offers the highest current stock level at 3724 units, followed by RN55E1002BB14 at 1210 units.

All three parts share identical RoHS non-compliance status, REACH Affected designation, ECCN EAR99 classification, and HTSUS code 8533.21.0090.

Frequently Asked Questions (FAQ)

Q: Can RN55E1002BB14 or RN55E1002BRE6 be used as direct replacements for RN55E1002CBSL?

A: Yes. Both substitutes are direct replacements. They maintain identical resistance values, power ratings, physical dimensions, operating temperature ranges, and military specifications. The substitutes offer improved tolerance (±0.1% versus ±0.25%), which provides tighter resistance accuracy.

Q: What is the difference between RN55E1002BB14 and RN55E1002BRE6?

A: The primary difference is packaging format. RN55E1002BB14 is supplied in Bulk packaging, while RN55E1002BRE6 is supplied in Cut Tape (CT) format. Both parts are electrically and mechanically identical. Cut Tape packaging is typically used for automated pick-and-place assembly, while Bulk packaging is used for manual assembly or reel-based processes.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical axial dimensions of 0.090" diameter by 0.240" length (2.29mm × 6.10mm). They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: Do the substitute parts meet the same military specifications?

A: Yes. All three parts conform to MIL-R-10509/7 specifications and are designated as Military series components. They share identical flame retardant coating, moisture resistance, and safety features.

Q: What is the significance of the improved tolerance in the substitute parts?

A: The substitute parts offer ±0.1% tolerance compared to the main part's ±0.25% tolerance. This means the actual resistance value will be closer to the nominal 10 kOhms specification. In precision analog circuits, measurement equipment, or calibration applications, tighter tolerance may be beneficial.

Q: Are there any compliance or certification differences between the parts?

A: No. All three parts share identical RoHS non-compliance status, REACH Affected designation, ECCN EAR99 classification, and HTSUS code 8533.21.0090. Compliance profiles are equivalent.
