Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC787R are identified based on the following critical parameters that determine functional equivalence:

• Resistance value: 787 Ohms (exact match required)
• Tolerance: ±1% (precision specification)
• Power rating: 0.25W / 1/4W (thermal capability)
• Composition: Metal Film (performance characteristics)
• Package: Axial (mechanical form factor)
• Temperature coefficient: ±50ppm/°C (stability specification)
• Compliance: ROHS3 Compliant (regulatory requirement)

The CMF50787R00FHEB from Vishay Dale meets all critical electrical and mechanical parameters. While physical dimensions differ slightly and operating temperature range extends to 175°C, these variations do not affect functional substitution in applications designed for the RNF14FTC787R.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC787R and CMF50787R00FHEB are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts should be based on:

• Packaging format: RNF14FTC787R is supplied in Tape & Reel (TR); CMF50787R00FHEB is supplied in Cut Tape (CT)
• Physical dimensions: RNF14FTC787R measures 0.093" Dia x 0.250" L; CMF50787R00FHEB measures 0.065" Dia x 0.150" L
• Extended temperature capability: CMF50787R00FHEB supports operation to 175°C versus 155°C for RNF14FTC787R
• Moisture resistance: CMF50787R00FHEB includes moisture resistant feature

Both parts satisfy the core electrical specifications (787 Ohms ±1%, 0.25W, metal film, ±50ppm/°C) required for direct substitution in circuit applications.
