Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65C2490FRSL 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 configuration: 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

The identified substitute part RN65C2490FB14 maintains identical electrical and mechanical specifications. The only difference is 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 RN65C2490FRSL and RN65C2490FB14 are active production components from Vishay Dale with identical electrical performance and mechanical compatibility. Selection between these parts is determined by packaging requirements:

• RN65C2490FRSL (Tape & Reel): Suitable for automated assembly processes requiring continuous reel feeding
• RN65C2490FB14 (Bulk): Suitable for manual assembly, kit builds, or applications where reel packaging is not required

Both parts maintain MIL-R-10509/2 military specification compliance and identical RoHS/REACH compliance status. Electrical performance, thermal characteristics, and reliability are equivalent across both packaging formats.

Frequently Asked Questions (FAQ)

Q: Can RN65C2490FB14 be used as a direct replacement for RN65C2490FRSL?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk vs. Tape & Reel). Substitution is valid for any application where the component specifications are met.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel packaging supplies components on continuous reels suitable for automated pick-and-place assembly equipment. Bulk packaging supplies loose components suitable for manual assembly or small-quantity applications. Both formats contain the same component with identical specifications.

Q: Are there any compliance differences between these parts?

A: No. Both parts share identical RoHS non-compliant and REACH Affected status. Military specification compliance (MIL-R-10509/2) is maintained across both packaging formats.

Q: What determines substitution eligibility for RN65 series resistors?

A: Substitution is valid when resistance value, tolerance, power rating, composition, package type, temperature coefficient, operating temperature range, and physical dimensions are identical. Packaging format variation alone does not prevent substitution.

Q: Can packaging format be changed during assembly?

A: Tape & Reel components can be manually removed and used in applications designed for Bulk components. However, Bulk components cannot be converted to Tape & Reel format. Verify assembly equipment compatibility before selecting packaging format.
