Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN60D6490FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 649 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package configuration: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 175°C
• Physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)
• Military series compliance: MIL-R-10509/1, RN60

The identified substitute part RN60D6490FB14 meets all electrical and mechanical requirements. The only difference between the main part and substitute 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 identical component specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RN60D6490FRE6 and RN60D6490FB14 are active products manufactured by Vishay Dale with identical electrical performance and military-grade specifications. Selection between these parts should be based on packaging requirements and supply chain logistics:

The RN60D6490FRE6 in Tape & Reel format is suitable for automated assembly processes and high-volume production environments where component feeding systems require reel-based packaging.

The RN60D6490FB14 in Bulk packaging is appropriate for manual assembly, repair operations, or applications where individual component handling is required.

Both parts maintain equivalent compliance status with RoHS non-compliance and REACH Affected designations. No electrical or thermal performance differences exist between the two options.

Frequently Asked Questions (FAQ)

Q: Can RN60D6490FB14 be used as a direct replacement for RN60D6490FRE6?

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

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 systems. Bulk packaging is used for manual assembly or component kitting. The resistor component itself is identical in both formats.

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

A: No. Both parts share identical RoHS status (non-compliant), REACH status (Affected), and military series designation (MIL-R-10509/1, RN60).

Q: What are the key parameters that determine substitution eligibility?

A: Resistance value (649 Ohms), tolerance (±1%), power rating (0.25W), composition (Metal Film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 175°C), and physical dimensions (0.145" Dia x 0.344" L) must remain constant for substitution.

Q: Can these parts be used interchangeably in military applications?

A: Yes, both parts conform to MIL-R-10509/1 specification and are rated for military applications. Packaging format does not affect military qualification status.
