Substitute Part Grouping Explanation

Substitution eligibility for the RN60D4993FRE6 is determined by the following critical parameters that must remain constant:

• Resistance value: 499 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package type: Axial
• Operating temperature range: -65°C to 175°C
• Series: RN60 military-grade classification
• Physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)

The RN60C4993FB14 qualifies as a direct substitute based on matching all electrical specifications and mechanical form factor. Variations in packaging format (Tape & Reel versus Bulk) and temperature coefficient do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RN60D4993FRE6 and RN60C4993FB14 are active production components manufactured by Vishay Dale within the military-grade RN60 series. Selection between these parts should be based on the following criteria:

The RN60D4993FRE6 is supplied in Tape & Reel packaging, suitable for automated assembly processes and high-volume production environments. The RN60C4993FB14 is supplied in Bulk packaging, appropriate for manual assembly, prototyping, or applications where individual component handling is required.

The RN60C4993FB14 offers improved temperature coefficient performance (±50ppm/°C versus ±100ppm/°C), providing superior stability across the full operating temperature range. This characteristic may be advantageous in precision analog circuits or temperature-sensitive applications.

Both parts maintain identical electrical specifications, mechanical dimensions, and compliance status. Neither part is RoHS compliant; both are REACH Affected and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can RN60C4993FB14 be used as a direct replacement for RN60D4993FRE6 in circuit applications?

A: Yes. Both components share identical resistance value, tolerance, power rating, composition, package type, and operating temperature range. The parts are electrically and mechanically interchangeable.

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

A: Tape & Reel packaging is designed for automated pick-and-place assembly equipment used in high-volume manufacturing. Bulk packaging supplies individual components suitable for manual assembly, prototyping, or low-volume applications. The electrical and mechanical properties of the resistor remain unchanged regardless of packaging format.

Q: Does the temperature coefficient difference affect substitution compatibility?

A: The RN60C4993FB14 features a lower temperature coefficient (±50ppm/°C) compared to the RN60D4993FRE6 (±100ppm/°C). This represents improved thermal stability and may provide performance benefits in temperature-sensitive circuits. The lower coefficient does not prevent substitution; it represents an enhancement in this parameter.

Q: Are both parts suitable for military applications?

A: Yes. Both the RN60D4993FRE6 and RN60C4993FB14 are classified within the military-grade RN60 series and comply with MIL-R-10509/1 specifications. Both feature flame retardant coating and moisture-resistant construction appropriate for military and high-reliability applications.

Q: What inventory considerations should guide part selection?

A: The RN60C4993FB14 maintains higher inventory availability (1809 units) compared to the RN60D4993FRE6 (834 units). For applications where supply continuity is critical, the substitute part offers greater stock availability.
