Key Parameters

Substitute Part Grouping Explanation

Substitution for the RCP2512W680RJS3 is determined by maintaining the following critical parameters:

• Resistance value: 680 Ohms (exact match required)
• Power rating: 4.6W (equal or greater acceptable)
• Package / Case: 2512 (6432 Metric) (exact match required for PCB compatibility)
• Composition: Thick Film (maintains electrical characteristics)
• Temperature Coefficient: ±150ppm/°C (matching thermal stability)
• Operating Temperature Range: -65°C ~ 155°C (minimum requirement)
• Features: Moisture Resistant (environmental protection maintained)
• Number of Terminations: 2 (circuit interface requirement)

The RCP2512W680RGEB qualifies as a direct substitute based on these parameters. The tolerance specification may vary (±2% versus ±5%) without affecting substitution eligibility, as tighter tolerance represents improved precision while maintaining backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RCP2512W680RJS3 and RCP2512W680RGEB maintain Active product status and are manufactured by Vishay Dale under the RCP series. Selection between these parts should consider regulatory compliance requirements. The RCP2512W680RGEB provides ROHS3 compliance, whereas the RCP2512W680RJS3 is RoHS non-compliant. For applications subject to RoHS3 regulations, the RCP2512W680RGEB is the appropriate selection. The improved tolerance specification (±2%) of the RCP2512W680RGEB provides enhanced precision without compromising any electrical or mechanical parameters required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W680RGEB replace RCP2512W680RJS3 in existing designs?

A: Yes. Both parts share identical resistance value (680 Ohms), power rating (4.6W), package dimensions (2512 / 6432 Metric), and operating temperature range (-65°C ~ 155°C). The mechanical footprint and electrical interface are fully compatible.

Q: What is the difference between ±5% and ±2% tolerance?

A: Tolerance defines the acceptable deviation from the nominal 680 Ohm resistance value. The RCP2512W680RJS3 allows ±5% deviation (646-714 Ohms), while RCP2512W680RGEB allows ±2% deviation (666.4-693.6 Ohms). The ±2% specification represents tighter precision and is suitable for applications requiring higher accuracy.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.250" L x 0.124" W (6.35mm x 3.15mm) with a maximum seated height of 0.025" (0.64mm). PCB layout and assembly processes require no modification.

Q: What is the significance of RoHS compliance difference?

A: RCP2512W680RGEB is ROHS3 compliant, while RCP2512W680RJS3 is RoHS non-compliant. For applications or markets requiring RoHS3 certification, the RCP2512W680RGEB is the mandated selection.

Q: Do both parts have the same moisture sensitivity?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are the temperature coefficients identical?

A: Yes. Both parts maintain ±150ppm/°C temperature coefficient, ensuring equivalent thermal stability across the -65°C ~ 155°C operating range.
