RN60D49R9FRE6 Equivalent & Substitute Parts

Part Overview

The RN60D49R9FRE6 is a 49.9 Ohm ±1% metal film through-hole resistor rated at 0.25W (1/4W) in axial package configuration. Manufactured by Vishay Dale under the military-grade RN60 series (MIL-R-10509/1), this component features flame retardant coating, moisture resistance, and safety-rated construction suitable for military and high-reliability applications. The part is currently active in production with 654 units in stock. Substitute parts are identified when packaging format differs while maintaining identical electrical and mechanical specifications, enabling procurement flexibility across different supply channels and inventory conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN60D49R9FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 49.9 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 × 0.344" L (3.68mm × 8.74mm)
• Series compliance: MIL-R-10509/1, RN60

The identified substitute part differs only in packaging format (Bulk versus Tape & Reel), which does not affect electrical performance or mechanical compatibility in circuit applications. Both parts maintain identical component specifications and military-grade construction.

Parameter Comparison

Engineering Selection Recommendations

Both RN60D49R9FRE6 and RN60D49R9FB14 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements and supply chain considerations:

• RN60D49R9FRE6 (Tape & Reel): Suitable for automated assembly processes requiring reel-based component feeding
• RN60D49R9FB14 (Bulk): Suitable for manual assembly, kit builds, or applications where reel packaging is not required

Both parts maintain equivalent compliance status (RoHS non-compliant, REACH Affected) and are suitable for military-grade applications requiring MIL-R-10509/1 specification compliance. Component selection should be based on assembly methodology and procurement logistics rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can RN60D49R9FB14 be used as a direct replacement for RN60D49R9FRE6?

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 RN60D49R9FRE6 is specified, provided assembly equipment compatibility with bulk packaging is confirmed.

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

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly systems. Bulk packaging is used for manual assembly, component kits, or applications where automated feeding is not required. Electrical performance is identical regardless of packaging format.

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). Compliance profiles are equivalent.

Q: What parameters must remain constant for substitution validity?

A: Resistance value (49.9 Ohms), tolerance (±1%), power rating (0.25W), composition (Metal Film), package type (Axial), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 175°C), and physical dimensions (0.145" Dia × 0.344" L) must all remain unchanged for substitution to be valid.

Q: Is inventory availability a factor in component selection?

A: Inventory levels may influence procurement decisions but do not affect technical substitution validity. RN60D49R9FRE6 has 654 units in stock, while RN60D49R9FB14 has 3959 units available. Both parts are active production items.
