Substitute Part Grouping Explanation

Substitute parts for the WR06X6190FTL are qualified based on electrical and mechanical parameter equivalence. The following criteria determine substitution eligibility:

Electrical Parameters:

• Resistance value: 619 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 0603 (1608 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Composition: Thick Film (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the WR06X6190FTL in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—WR06X6190FTL (Walsin Technology Corporation), CR0603-10W-6190FT (Venkel), and CR166190F (Meritek)—are classified as Active product status and are fully RoHS3 compliant. Each part carries MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.

The substitute parts CR0603-10W-6190FT and CR166190F are electrically and mechanically equivalent to the primary part WR06X6190FTL. The seated height difference between the primary part (0.024" / 0.60mm) and the substitute parts (0.022" / 0.55mm) is within acceptable tolerance for standard PCB assembly processes and does not affect circuit functionality or board-level compatibility.

Selection between these parts is determined by availability, supply chain requirements, and procurement preferences. All parts are suitable for direct substitution in applications requiring a 619 Ohm ±1% 0.1W thick film chip resistor in 0603 package format.
