Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCP2512B680RJS2 is determined by the following critical parameters:

• Resistance Value: Must be 680 Ohms
• Package / Case: Must be 2512 (6432 Metric)
• Power Rating: Must be 4.6W minimum
• Composition: Must be Thick Film
• Temperature Coefficient: Must be ±150ppm/°C or better
• Operating Temperature Range: Must cover -65°C ~ 155°C
• Features: Must include Moisture Resistant capability
• Moisture Sensitivity Level: Must be MSL 1 (Unlimited)

The RCP2512W680RGEB qualifies as a direct substitute based on these parameters. The primary distinction is an improved tolerance specification (±2% versus ±5%), which represents an upgrade in precision without altering electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W680RGEB serves as a direct functional equivalent to the RCP2512B680RJS2 with two key distinctions:

Tolerance Upgrade: The substitute provides ±2% tolerance compared to the original ±5%, offering improved precision for applications requiring tighter resistance specifications.

Compliance Enhancement: The RCP2512W680RGEB achieves ROHS3 compliance, whereas the RCP2512B680RJS2 is RoHS non-compliant. Selection should be based on regulatory requirements and end-application compliance mandates.

Both components maintain identical electrical performance characteristics, mechanical dimensions, and thermal operating parameters. Footprint compatibility is assured for direct PCB substitution.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W680RGEB replace RCP2512B680RJS2 in existing designs?

A: Yes. Both components share identical package dimensions (2512), resistance value (680 Ohms), power rating (4.6W), and operating temperature range (-65°C ~ 155°C). PCB footprints are directly compatible.

Q: What is the primary difference between these two parts?

A: The RCP2512W680RGEB provides improved tolerance (±2% versus ±5%) and achieves ROHS3 compliance. Electrical and mechanical specifications remain equivalent.

Q: Are the physical dimensions identical?

A: Yes. Both components measure 0.250" L x 0.124" W (6.35mm x 3.15mm) with a maximum seated height of 0.025" (0.64mm).

Q: Does tolerance difference affect circuit performance?

A: Tolerance affects resistance value accuracy. The ±2% specification of RCP2512W680RGEB provides tighter value distribution. Selection depends on circuit requirements for resistance precision.

Q: Is RoHS compliance a factor in substitution?

A: RoHS compliance is a regulatory and supply chain consideration. The RCP2512W680RGEB's ROHS3 compliance may be required for specific markets or applications. The RCP2512B680RJS2 is non-compliant.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both components operate across the identical temperature range of -65°C ~ 155°C with matching temperature coefficients of ±150ppm/°C.
