Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C1502DB14 is determined by the following critical parameters:

• Resistance Value: Must be exactly 15 kOhms
• Power Rating: Must be 0.125W (1/8W) minimum
• Package Type: Must be Axial configuration
• Temperature Coefficient: Must be ±50ppm/°C or better
• Operating Temperature Range: Must support -65°C to 175°C
• Series Compliance: Must belong to RN55 military series (MIL-R-10509/7)
• Composition: Must be Metal Film
• Features: Must include Flame Retardant Coating and Moisture Resistance

The RN55C1502BB14 qualifies as a direct substitute because it maintains identical resistance value, power rating, package configuration, temperature coefficient, operating range, series classification, and physical dimensions. The primary difference is an improved tolerance specification (±0.1% versus ±0.5%), which represents an upgrade path for applications requiring tighter tolerance control without compromising any other electrical or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C1502DB14 and RN55C1502BB14 are active production components from Vishay Dale with identical military-grade certifications, compliance status, and regulatory classifications. Selection between these parts should be based on tolerance requirements:

• RN55C1502DB14 (±0.5% tolerance): Suitable for applications where standard tolerance specifications are acceptable and cost optimization is a priority.
• RN55C1502BB14 (±0.1% tolerance): Appropriate for precision circuit designs requiring tighter tolerance control, such as high-accuracy measurement circuits, calibration networks, or applications with stringent performance specifications.

Both components maintain identical RoHS non-compliant and REACH Affected status, ensuring consistent regulatory treatment in supply chain documentation and compliance reporting.

Frequently Asked Questions (FAQ)

Q: Can RN55C1502BB14 be used as a direct replacement for RN55C1502DB14?

A: Yes. The RN55C1502BB14 is electrically and mechanically compatible with the RN55C1502DB14. Both components share identical resistance value (15 kOhms), power rating (0.125W), package configuration (Axial), temperature coefficient (±50ppm/°C), operating temperature range (-65°C to 175°C), and physical dimensions (0.090" Dia x 0.240" L). The substitute offers improved tolerance specification (±0.1% versus ±0.5%).

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. The RN55C1502DB14 has ±0.5% tolerance, while the RN55C1502BB14 has ±0.1% tolerance. This means the RN55C1502BB14 maintains resistance values closer to the nominal 15 kOhms specification, making it suitable for precision applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical axial package dimensions of 0.090" diameter by 0.240" length (2.29mm x 6.10mm), ensuring identical PCB footprint and mounting compatibility.

Q: Do both parts meet military specifications?

A: Yes. Both components are manufactured to MIL-R-10509/7 military standards as part of the RN55 series and include flame retardant coating and moisture resistance features.

Q: What is the inventory status for each part?

A: RN55C1502DB14 has 811 units in stock. RN55C1502BB14 has 960 units in stock. Both are listed as new original components.
