Substitute Part Grouping Explanation

Substitution eligibility for the RN65C2490FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 249 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Package type: Axial
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -65°C to 175°C
• Physical dimensions: 0.180" Dia x 0.562" L
• Series compliance: MIL-R-10509/2, RN65
• Feature set: Flame Retardant Coating, Military, Moisture Resistant, Safety

The identified substitute part RN65C2490FB14 maintains identical electrical and mechanical specifications. The only difference is the packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Bulk packaging. Both parts are manufactured by Vishay Dale and share the same base product number (RN65).

Parameter Comparison

Engineering Selection Recommendations

Both RN65C2490FRE6 and RN65C2490FB14 are active production parts from Vishay Dale with identical electrical performance and military-grade specifications. Selection between these parts should be based on packaging requirements and assembly process compatibility:

• RN65C2490FRE6 (Tape & Reel): Suitable for automated pick-and-place assembly operations and high-volume production environments requiring reel-based component feeding.
• RN65C2490FB14 (Bulk): Suitable for manual assembly, low-volume production, or applications where bulk packaging is preferred.

Both parts maintain RoHS non-compliant and REACH Affected status. Compliance requirements for your specific application must be verified independently. No functional or performance differences exist between these parts; substitution is purely a packaging format consideration.

Frequently Asked Questions (FAQ)

Q: Can RN65C2490FB14 be used as a direct replacement for RN65C2490FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk vs. Tape & Reel). Substitution is valid provided your assembly process can accommodate the bulk packaging format.

Q: Are there any performance differences between the two parts?

A: No. Both parts share identical resistance (249 Ohms), tolerance (±1%), power rating (0.5W), temperature coefficient (±50ppm/°C), operating temperature range (-65°C to 175°C), and physical dimensions (0.180" Dia x 0.562" L).

Q: What is the significance of the packaging format difference?

A: Tape & Reel (TR) packaging is optimized for automated assembly lines with reel-feeding equipment. Bulk packaging is used for manual assembly or applications where component feeding equipment is not available. The electrical and mechanical performance is identical.

Q: Are both parts still in active production?

A: Yes. Both RN65C2490FRE6 and RN65C2490FB14 maintain active product status with Vishay Dale.

Q: Do these parts meet RoHS or REACH compliance?

A: Both parts are RoHS non-compliant and REACH Affected. If your application requires RoHS or REACH compliance, alternative components must be sourced.

Q: What is the MIL-R-10509/2 specification?

A: MIL-R-10509/2 is a military standard specification for fixed resistors. Both parts comply with this specification, confirming their suitability for military and aerospace applications.
