Substitute Part Grouping Explanation

The RN65C4990FB14 qualifies as a direct substitute for the RN65C4990FRE6 based on identical electrical and mechanical parameters. Both parts share the same base product number (RN65), resistance value (499 Ohms), tolerance (±1%), power rating (0.5W), composition (metal film), temperature coefficient (±50ppm/°C), operating temperature range (-65°C to 175°C), package type (axial), and physical dimensions (0.180" Dia × 0.562" L). The substitution is valid across all electrical performance criteria and mechanical compatibility requirements. The primary difference is packaging format: RN65C4990FRE6 is supplied in tape and reel (TR) configuration, while RN65C4990FB14 is supplied in bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

Both RN65C4990FRE6 and RN65C4990FB14 are active production components from Vishay Dale with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on procurement and assembly requirements. The RN65C4990FRE6 in tape and reel packaging is optimized for automated assembly processes and high-volume production environments. The RN65C4990FB14 in bulk packaging is suitable for manual assembly, repair operations, or applications where tape and reel format is not required. Both parts maintain RoHS non-compliant status and REACH affected classification. Compliance requirements and regulatory obligations should be evaluated independently of substitution eligibility.

Frequently Asked Questions (FAQ)

Q: Can RN65C4990FB14 replace RN65C4990FRE6 in production assembly? A: Yes. Both parts are electrically and mechanically identical. The RN65C4990FB14 bulk packaging requires manual handling or alternative feeder systems compared to the tape and reel format of RN65C4990FRE6. Assembly process compatibility should be confirmed with your production equipment specifications.

Q: Are there any electrical performance differences between these parts? A: No. Both parts share identical resistance value (499 Ohms), tolerance (±1%), power rating (0.5W), temperature coefficient (±50ppm/°C), and operating temperature range (-65°C to 175°C).

Q: What is the primary difference between these substitute parts? A: The packaging format differs. RN65C4990FRE6 is supplied in tape and reel configuration for automated assembly. RN65C4990FB14 is supplied in bulk packaging for manual assembly or alternative handling methods.

Q: Are both parts suitable for military applications? A: Yes. Both parts are classified as military-grade components per MIL-R-10509/2 specifications and feature flame retardant coating, moisture resistance, and safety-rated construction.

Q: Do these parts have different inventory availability? A: Current inventory levels differ. RN65C4990FRE6 has 789 units available, while RN65C4990FB14 has 1014 units available. Inventory status is subject to change and should be confirmed at time of procurement.

Q: Can I use RN65C4990FB14 as a direct drop-in replacement? A: Yes, for electrical and mechanical compatibility. Physical installation is identical due to matching axial package dimensions (0.180" Dia × 0.562" L). Packaging format handling procedures may differ based on your assembly method.
