Key Parameters

Substitute Part Grouping Explanation

Substitution for the RCP2512W100RJS3 is determined by strict equivalence in the following critical parameters:

• Resistance value: 100 Ohms (exact match required)
• Power rating: 4.6W (exact match required)
• Package / Case: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -65°C ~ 155°C (exact match required)
• Temperature coefficient: ±150ppm/°C (exact match required)
• Moisture resistance feature: Present (exact match required)

Tolerance may vary within acceptable substitution parameters. The RCP2512W100RGEB qualifies as a substitute due to matching all critical electrical and mechanical specifications while offering improved tolerance performance.

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W100RGEB serves as a direct substitute for the RCP2512W100RJS3 based on identical electrical specifications and mechanical compatibility. The substitute part maintains the same 100 Ohm resistance, 4.6W power rating, 2512 package dimensions, and operating temperature range.

The primary distinction is tolerance specification: RCP2512W100RGEB provides ±2% tolerance compared to the ±5% tolerance of the main part. This represents improved precision without altering circuit functionality or thermal characteristics.

RCP2512W100RGEB achieves ROHS3 compliance, whereas RCP2512W100RJS3 is RoHS non-compliant. Selection between these parts depends on regulatory and environmental requirements applicable to the end application.
