Substitute Part Grouping Explanation

Substitution eligibility for the RN60D1781FRE6 is determined by strict equivalence across the following critical parameters:

  • Resistance value: 1.78 kOhms
  • 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. All other specifications remain identical.

Engineering Selection Recommendations

Both the RN60D1781FRE6 and RN60D1781FB14 are active production components manufactured by Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on procurement requirements and supply chain considerations:

The RN60D1781FRE6 (Tape & Reel packaging) is suitable for automated assembly processes and high-volume production environments where component feeding systems require reel-based delivery.

The RN60D1781FB14 (Bulk packaging) is suitable for manual assembly, low-volume production, or applications where individual component handling is preferred.

Both parts maintain compliance with MIL-R-10509/1 military specifications and carry identical RoHS non-compliant and REACH Affected designations. No electrical performance difference exists between the two packaging formats.

Frequently Asked Questions (FAQ)

Q: Can RN60D1781FB14 be used as a direct replacement for RN60D1781FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk versus Tape & Reel). Circuit performance, reliability, and compliance characteristics are equivalent.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel or Bulk) does not affect electrical performance, tolerance, temperature coefficient, or operating characteristics. The resistor element and physical dimensions are identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts share identical RoHS non-compliant and REACH Affected designations. Military series classification (MIL-R-10509/1, RN60) applies to both.

Q: Which part should be selected for automated assembly?

A: The RN60D1781FRE6 (Tape & Reel) is designed for automated component placement systems. The RN60D1781FB14 (Bulk) is suitable for manual assembly or applications without automated feeding requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.145" Dia × 0.344" L (3.68mm × 8.74mm) and fit identical PCB footprints and through-hole spacing.
