Substitute Part Grouping Explanation

Substitution eligibility for the RC1608J915CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 9.1 MOhms
• Package / Case: 0603 (1608 Metric)
• Power rating: 0.1W (1/10W)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C
• Temperature coefficient: ±100ppm/°C
• Physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm)
• Number of terminations: 2
• Moisture resistance: Required

Tolerance Consideration: The RC1608J915CS specifies ±5% tolerance. Direct equivalents maintain this tolerance specification. Upgrade substitutes may offer improved tolerance (±1%) while maintaining all other electrical and mechanical parameters.

Compliance Requirements: All substitute parts must maintain RoHS3 compliance, MSL 1 rating, and REACH Unaffected status to ensure regulatory and environmental compatibility.
