Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCP2512B100RJS2 is determined by the following critical parameters:

• Resistance Value: Must be 100 Ohms
• Package / Case: Must be 2512 (6432 Metric) for mechanical and electrical compatibility
• Power Rating: Must be 4.6W or greater
• 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 construction
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The RCP2512W100RGEB qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±2% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W100RGEB provides functional equivalence to the RCP2512B100RJS2 with the following considerations:

Tolerance Improvement: The substitute part offers ±2% tolerance compared to ±5% in the main part. This tighter tolerance may provide improved circuit performance in applications where resistance accuracy is critical.

Compliance Status: The RCP2512W100RGEB is ROHS3 compliant, whereas the RCP2512B100RJS2 is RoHS non-compliant. Selection should align with regulatory requirements applicable to the end application and target market.

Electrical and Mechanical Compatibility: Both parts maintain identical resistance value, power rating, package dimensions, temperature coefficient, and operating temperature range, ensuring direct functional substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W100RGEB be used as a direct replacement for RCP2512B100RJS2?

A: Yes. Both parts share identical resistance value (100 Ohms), power rating (4.6W), package type (2512), temperature coefficient (±150ppm/°C), and operating temperature range (-65°C ~ 155°C). The substitute offers improved tolerance specification and enhanced RoHS compliance.

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

A: The main differences are tolerance specification (±2% versus ±5%) and RoHS compliance status (ROHS3 Compliant versus RoHS non-compliant). Electrical performance and mechanical compatibility remain equivalent.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 2512 (6432 Metric) case with identical dimensions of 0.250" L x 0.124" W (6.35mm x 3.15mm) and maximum seated height of 0.025" (0.64mm). PCB layout and assembly processes require no modification.

Q: Does the ±2% tolerance of the substitute part affect circuit design?

A: The tighter tolerance of RCP2512W100RGEB may improve circuit accuracy in applications sensitive to resistance variation. Existing designs using RCP2512B100RJS2 will function with the substitute without circuit modification.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, provided standard ESD precautions are observed.
