Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP2512W680RJS2 is determined by the following critical parameters that must remain constant:

• Resistance value: 680 Ohms
• Power rating: 4.6W
• Package type: 2512 (6432 Metric)
• Physical dimensions: 0.250" L x 0.124" W (6.35mm x 3.15mm)
• Composition: Thick Film
• Temperature coefficient: ±150ppm/°C
• Operating temperature range: -65°C ~ 155°C
• Moisture resistant construction
• Number of terminations: 2

The RCP2512W680RGEB qualifies as a direct substitute based on these parameters. The primary difference is an improved tolerance specification (±2% versus ±5%) and enhanced RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W680RGEB serves as a direct functional substitute for the RCP2512W680RJS2 in applications where component specifications and package compatibility are primary selection criteria. Both parts maintain identical electrical performance across the specified operating temperature range and share identical physical dimensions for PCB layout compatibility.

Selection between these parts should be based on regulatory and compliance requirements. The RCP2512W680RGEB provides ROHS3 compliance, making it suitable for applications subject to RoHS3 regulations. The RCP2512W680RJS2 remains appropriate for applications without RoHS compliance mandates.

The improved tolerance specification of the RCP2512W680RGEB (±2% versus ±5%) provides tighter resistance accuracy, which may be beneficial in precision circuit applications where resistance value stability is critical.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W680RGEB replace RCP2512W680RJS2 in existing designs?
