RN60C4993FRE6 Equivalent & Substitute Parts

Part Overview

The RN60C4993FRE6 is a 499 kOhms ±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 869 units in stock. Substitute parts may be required due to packaging availability, inventory constraints, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN60C4993FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 499 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Physical dimensions: 0.145" Dia × 0.344" L (exact match required)
• Series: RN60 military-grade (exact match required)

The primary variable among qualified substitutes is packaging format (Tape & Reel versus Bulk), which does not affect electrical or mechanical performance. All substitute parts must maintain identical electrical specifications and physical form factor to ensure direct interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RN60C4993FRE6 and RN60C4993FB14 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on procurement requirements and packaging format compatibility:

The RN60C4993FRE6 (Tape & Reel packaging) is suitable for automated assembly processes and high-volume production environments where component feeding systems require reel-based delivery.

The RN60C4993FB14 (Bulk packaging) is suitable for manual assembly, low-volume production, or applications where reel packaging is not required.

Both parts maintain equivalent compliance status: RoHS non-compliant and REACH Affected. No electrical or thermal performance differences exist between these alternatives. Physical form factor and mounting characteristics are identical, ensuring direct substitution in circuit board layouts without design modification.

Frequently Asked Questions (FAQ)

Q: Can RN60C4993FB14 be used as a direct replacement for RN60C4993FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk versus Tape & Reel). Direct substitution is possible provided the receiving assembly process is compatible with bulk packaging.

Q: What is the primary difference between these substitute parts?

A: The packaging format differs. RN60C4993FRE6 arrives in Tape & Reel format for automated pick-and-place assembly. RN60C4993FB14 arrives in Bulk format for manual handling or alternative assembly methods. Electrical performance and physical dimensions are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts share identical RoHS and REACH status. Both are military-grade components compliant with MIL-R-10509/1 specifications.

Q: Will substitution require circuit board redesign?

A: No. Physical dimensions, pin configuration, and electrical characteristics are identical. No PCB layout or schematic modifications are necessary.

Q: What inventory levels are available for each part?

A: RN60C4993FRE6 (Tape & Reel) has 869 units in stock. RN60C4993FB14 (Bulk) has 1809 units in stock.
