Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C1502CBSL is determined by the following critical parameters:

• Resistance Value: Must be 15 kOhms
• Power Rating: Must be 0.125W (1/8W) minimum
• Package Configuration: Must be axial through-hole
• Composition: Must be metal film
• Temperature Coefficient: Must be ±50ppm/°C or better
• Operating Temperature Range: Must support -65°C to 175°C
• Series Compliance: Must belong to MIL-R-10509/7 military specification

The RN55C1502BB14 qualifies as a direct substitute because it maintains identical resistance, power rating, package type, temperature coefficient, and operating range. The tolerance specification (±0.1% versus ±0.25%) represents an upgrade in accuracy without affecting functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C1502CBSL and RN55C1502BB14 maintain active product status and identical compliance certifications (RoHS non-compliant, REACH Affected, ECCN EAR99). The RN55C1502BB14 provides improved tolerance specification (±0.1% versus ±0.25%) while maintaining all other electrical and mechanical characteristics. Selection between these parts depends on circuit tolerance requirements and application-specific accuracy specifications. Both components are suitable for military-grade applications requiring MIL-R-10509/7 compliance.

Frequently Asked Questions (FAQ)

Q: Can RN55C1502BB14 replace RN55C1502CBSL in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package configuration, temperature coefficient, and operating temperature range. The substitute offers improved tolerance accuracy without affecting mechanical or thermal compatibility.

Q: Are there physical dimension differences between these parts?

A: No. Both components have identical axial package dimensions of 0.090" diameter × 0.240" length (2.29mm × 6.10mm), ensuring direct board-level compatibility.

Q: What is the significance of the tolerance difference?

A: The RN55C1502BB14 provides ±0.1% tolerance compared to ±0.25% for the RN55C1502CBSL. This represents tighter resistance accuracy. Applications requiring higher precision benefit from the substitute part, while circuits tolerant of ±0.25% variation function identically with either component.

Q: Do both parts meet military specifications?

A: Yes. Both components comply with MIL-R-10509/7 military specification and belong to the RN55 series, featuring flame retardant coating, moisture resistance, and safety certification.

Q: Are there compliance or regulatory differences?

A: No. Both parts share identical RoHS non-compliant and REACH Affected status, with matching ECCN EAR99 and HTSUS classifications.
