Key Parameters

Substitute Part Grouping Explanation

Substitution within the RN70 series is determined by the following critical parameters: resistance value (250 Ohms), power rating (0.75W), package type (Axial), physical dimensions (0.180" Dia x 0.562" L), operating temperature range (-65°C to 175°C), and composition (Metal Film). The RN70E2500BB14 qualifies as a direct substitute because it maintains identical resistance, power rating, package configuration, dimensions, and temperature range. Differences in tolerance (±0.1% versus ±1%), temperature coefficient (±25ppm/°C versus ±50ppm/°C), and packaging format (Bulk versus Tape & Reel) represent upgrades in precision and availability rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

Both RN70C2500FRE6 and RN70E2500BB14 maintain active product status and identical compliance classifications (RoHS non-compliant, REACH Affected, ECCN EAR99). Selection between these parts depends on application-specific requirements: the RN70C2500FRE6 is appropriate for standard military applications requiring ±1% tolerance and Tape & Reel packaging format; the RN70E2500BB14 is suitable for applications demanding tighter tolerance control (±0.1%) and lower temperature coefficient drift (±25ppm/°C versus ±50ppm/°C), with Bulk packaging availability. Both parts satisfy MIL-R-10509/3 military specifications and maintain identical electrical performance within their respective tolerance bands across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RN70E2500BB14 replace RN70C2500FRE6 in existing designs? A: Yes. Both parts share identical resistance (250 Ohms), power rating (0.75W), physical dimensions (0.180" Dia x 0.562" L), package type (Axial), and operating temperature range (-65°C to 175°C). The RN70E2500BB14 offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient, making it functionally compatible and electrically superior for precision applications.

Q: What is the difference in packaging between these parts? A: RN70C2500FRE6 is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. RN70E2500BB14 is supplied in Bulk format, appropriate for manual assembly or alternative handling requirements. Both maintain identical component specifications.

Q: Are there compliance or certification differences? A: No. Both parts share identical RoHS status (non-compliant), REACH status (Affected), and ECCN classification (EAR99). Both conform to MIL-R-10509/3 military specifications and maintain active product status.

Q: Which part should be selected for temperature-sensitive applications? A: RN70E2500BB14 is preferred for temperature-sensitive applications due to its lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), resulting in reduced resistance drift across the -65°C to 175°C operating range.

Q: Are the physical dimensions identical? A: Yes. Both parts maintain identical axial package dimensions of 0.180" diameter by 0.562" length (4.57mm x 14.27mm), ensuring mechanical compatibility in PCB layouts and through-hole assemblies.
