Parameter Comparison

Engineering Selection Recommendations

Both the RN55C1500FRE6 and RN55E1500BB14 are active military-grade components manufactured by Vishay Dale under the MIL-R-10509/7 specification. Selection between these parts should be based on the following criteria:

Select RN55C1500FRE6 when:

• Cut Tape packaging format is required for automated assembly processes
• Standard ±1% tolerance meets circuit requirements
• Temperature coefficient of ±50ppm/°C is acceptable for the application

Select RN55E1500BB14 when:

• Bulk packaging format is acceptable or preferred
• Tighter ±0.1% tolerance is required for precision circuits
• Lower temperature coefficient of ±25ppm/°C improves circuit stability across temperature extremes
• Enhanced electrical performance characteristics are beneficial

Both parts maintain identical mechanical compatibility, environmental ratings, and military compliance status. The choice between them is determined by tolerance requirements, temperature stability needs, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can RN55E1500BB14 be used as a direct replacement for RN55C1500FRE6?

A: Yes. Both components share identical resistance values, power ratings, physical dimensions, operating temperature ranges, and axial package configuration. The RN55E1500BB14 features improved tolerance and temperature coefficient specifications, making it electrically compatible and functionally superior in precision applications.

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

A: The RN55E1500BB14 provides tighter tolerance (±0.1% versus ±1%) and improved temperature stability (±25ppm/°C versus ±50ppm/°C). Packaging format differs: RN55C1500FRE6 is supplied in Cut Tape, while RN55E1500BB14 is supplied in Bulk.

Q: Are both parts MIL-R-10509/7 compliant?

A: Yes. Both the RN55C1500FRE6 and RN55E1500BB14 are manufactured to the Military, MIL-R-10509/7, RN55 series specification and maintain identical military-grade construction features including flame retardant coating and moisture resistance.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape and Bulk packaging formats do not affect the electrical characteristics of the resistor. The difference is in supply and handling format only. Cut Tape is optimized for automated pick-and-place assembly, while Bulk format is used for manual assembly or alternative handling processes.

Q: Which part should be selected for high-precision circuit applications?

A: The RN55E1500BB14 is the appropriate selection for high-precision applications due to its ±0.1% tolerance and ±25ppm/°C temperature coefficient, both of which provide superior stability and accuracy compared to the RN55C1500FRE6.

Q: Are both parts currently in stock?

A: Yes. The RN55C1500FRE6 has 1948 units in stock, and the RN55E1500BB14 has 1769 units in stock, both listed as new original inventory.
