Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN60C2490FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 249 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -65°C to 175°C
• Package configuration: Axial
• Physical dimensions: 0.145" Dia × 0.344" L
• Series compliance: RN60, MIL-R-10509/1
• Feature set: Flame retardant coating, moisture resistance, safety rating

The identified substitute part RN60C2490FB14 maintains identical electrical and mechanical specifications. The primary distinction is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Bulk packaging. Both parts share the same base product number (RN60) and comply with identical military and safety standards.

Parameter Comparison

Engineering Selection Recommendations

Both RN60C2490FRE6 and RN60C2490FB14 are active products from Vishay Dale with identical electrical performance and military-grade specifications. Selection between these parts should be based on procurement and assembly requirements:

RN60C2490FRE6 (Tape & Reel packaging) is suitable for automated assembly processes requiring continuous component feed from tape reels.

RN60C2490FB14 (Bulk packaging) is suitable for manual assembly, kit builds, or applications where tape-and-reel format is not required.

Both parts maintain equivalent compliance status: RoHS non-compliant and REACH Affected. Inventory availability differs, with RN60C2490FB14 currently stocked at higher quantities (1329 units versus 670 units).

Frequently Asked Questions (FAQ)

Q: Can RN60C2490FB14 be used as a direct replacement for RN60C2490FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk versus Tape & Reel). Substitution is valid for any application where the RN60C2490FRE6 is specified, provided the assembly process can accommodate bulk packaging.

Q: What is the significance of the packaging difference between these parts?

A: Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment. Bulk packaging is supplied loose or in standard containers and is typically used for manual assembly or non-automated processes. The electrical and mechanical performance of the resistor itself is identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts share identical RoHS and REACH status. Both comply with MIL-R-10509/1 military specifications and carry the same feature set (flame retardant coating, moisture resistance, safety rating).

Q: Which part should be selected for new designs?

A: Selection depends on manufacturing process requirements. For automated assembly lines, RN60C2490FRE6 (Tape & Reel) is standard. For manual assembly or prototype builds, RN60C2490FB14 (Bulk) may be more practical. Both are active products with equivalent long-term availability.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.145" diameter × 0.344" length (3.68mm × 8.74mm) in axial configuration. PCB footprint and mounting requirements are identical.
