Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F1R5CS is determined by strict equivalence across the following criteria:

Electrical Parameters: Resistance value must be 1.5 Ohms with tolerance of ±1%. Power rating must be 0.063W (1/16W) minimum. Operating temperature range must encompass or equal -55°C to 155°C.

Mechanical Parameters: Package format must be 0402 (1005 Metric). Physical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and maximum seated height (0.016" / 0.40mm) must be identical. Number of terminations must be 2.

Material & Composition: Thick film construction is required. Moisture resistance feature must be present.

Compliance & Certification: RoHS3 compliance is mandatory. MSL rating must be Level 1 or equivalent. REACH Unaffected status must be maintained.

The identified substitute RC0402FR-071R5L from YAGEO meets all these criteria and is classified as an equivalent part.
