Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F8254CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 8.25 MOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package type: 0603 (1608 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

Substitute parts are classified into two categories: Direct equivalents share identical specifications across all parameters; similar parts meet all electrical and mechanical requirements with additional certifications or minor dimensional variations within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

RC0603FR-078M25L (YAGEO) qualifies as a direct equivalent substitute for RC1608F8254CS. All electrical parameters, mechanical dimensions, and compliance certifications are identical.
