Substitute Part Grouping Explanation

Substitute parts for the RCS3216F1584CS are identified based on strict electrical and mechanical parameter alignment. The substitution logic requires exact matching of the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 1.58 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 1206 footprint

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant status
• Moisture Sensitivity Level: MSL 1 or better
• REACH Unaffected status

The RC1206FR-071M58L from YAGEO satisfies all critical substitution criteria and qualifies as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RC1206FR-071M58L from YAGEO qualifies as a direct substitute for the RCS3216F1584CS based on complete alignment of electrical specifications, mechanical compatibility, and regulatory compliance.

Selection Basis:

All critical electrical parameters match exactly: 1.58 MOhms resistance, ±1% tolerance, 0.25W power rating, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. Both components utilize thick film composition and maintain identical performance characteristics across the specified operating envelope.

Mechanical compatibility is confirmed through identical 1206 (3216 Metric) package designation and two-termination configuration. Minor dimensional variations (0.126" vs 0.122" length; 0.66mm vs 0.65mm height) fall within standard 1206 footprint tolerances and present no PCB layout or assembly concerns.

Regulatory compliance is equivalent: both parts carry ROHS3 Compliant certification, MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status. No additional qualification or testing is required for substitution in applications originally designed for the RCS3216F1584CS.
