Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP2512B680RJS3 is determined by strict equivalence in the following parameters:

• Resistance value: 680 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)
• Temperature Coefficient: ±150ppm/°C (exact match required)
• Operating Temperature Range: -65°C ~ 155°C (exact match required)
• Moisture Resistant feature (required)

Tolerance and RoHS compliance status are permitted to vary within the substitute group, as these parameters do not affect physical or thermal compatibility. The identified substitute part RCP2512W680RGEB maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±2% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

Both the RCP2512B680RJS3 and RCP2512W680RGEB are active products from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

The RCP2512B680RJS3 is suitable for applications where RoHS non-compliant components are acceptable and standard ±5% tolerance meets circuit requirements.

The RCP2512W680RGEB is the preferred selection for applications requiring ROHS3 compliance certification. Additionally, this part offers improved tolerance specification at ±2%, providing tighter resistance value control compared to the ±5% tolerance of the primary part. Both components are electrically and mechanically interchangeable in 2512 package footprints.

Frequently Asked Questions (FAQ)

Q: Are RCP2512B680RJS3 and RCP2512W680RGEB physically interchangeable?

A: Yes. Both parts share identical package dimensions (2512 / 6432 Metric), footprint requirements, and mounting specifications. They are direct mechanical substitutes suitable for the same PCB layout.

Q: What is the difference in tolerance between these parts?

A: The RCP2512B680RJS3 has ±5% tolerance, while the RCP2512W680RGEB has ±2% tolerance. The ±2% specification provides tighter resistance value control and may be required for precision circuit applications.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance status reflects manufacturing process and material composition but does not alter electrical characteristics, power rating, temperature coefficient, or operating temperature range. Selection should be based on regulatory or procurement requirements.

Q: Can I substitute RCP2512W680RGEB for RCP2512B680RJS3 in existing designs?

A: Yes. The RCP2512W680RGEB maintains all critical electrical and mechanical parameters. The improved tolerance specification (±2%) is a beneficial upgrade that does not require circuit redesign.

Q: Are there any thermal or frequency limitations for these 2512 resistors?

A: Both parts operate across the -65°C ~ 155°C temperature range with ±150ppm/°C temperature coefficient. No frequency limitations are specified in the provided parameters.
