Substitute Part Grouping Explanation

Substitute parts for the RC6432F100CS are grouped into two categories based on electrical and mechanical compatibility:

Category 1: Direct Electrical Equivalents (1W Power Rating) Parts matching all primary electrical specifications: 10 Ohms resistance, ±1% tolerance, 1W power rating, ±100 ppm/°C temperature coefficient, -55°C to 155°C operating range, and 2512 package format. These parts are interchangeable in applications where the original 1W specification is required.

Category 2: Upgraded Power Rating Substitutes (1.5W–2W Power Rating) Parts with identical electrical specifications except for increased power dissipation capability (1.5W or 2W). These substitutes maintain all other parameters including resistance, tolerance, temperature coefficient, and operating temperature range. Upgraded power ratings provide design margin and are suitable for applications with higher thermal stress or pulse conditions.

Key Parameters Determining Substitution:

Resistance value: 10 Ohms (exact match required)
Tolerance: ±1% (exact match required)
Temperature Coefficient: ±100 ppm/°C (exact match required)
Operating Temperature: -55°C to 155°C (exact match required)
Package: 2512 (6432 Metric) (exact match required)
Composition: Thick Film (exact match required)
Terminations: 2 (exact match required)
Power Rating: 1W minimum (equal or higher acceptable)
