Key Parameters

Substitute Part Grouping Explanation

Substitution for the RCP2512B100RJS3 is determined by strict equivalence in the following critical parameters:

• Resistance value: 100 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)
• Features: Moisture Resistant (exact match required)
• Number of Terminations: 2 (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Tolerance may vary within the acceptable range for the application. Substitute parts must maintain all other electrical and mechanical specifications identically.

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W100RGEB serves as a direct substitute for the RCP2512B100RJS3 with the following considerations based on provided specifications:

Electrical equivalence is maintained across all critical parameters: resistance, power rating, temperature coefficient, and operating temperature range. Both components are manufactured by Vishay Dale in the identical 2512 package with matching physical dimensions and termination configuration.

The primary distinction is tolerance specification: RCP2512W100RGEB provides ±2% tolerance compared to ±5% in the RCP2512B100RJS3. This represents improved precision without altering functional compatibility.

RoHS compliance status differs: RCP2512B100RJS3 is RoHS non-compliant while RCP2512W100RGEB is ROHS3 compliant. Selection between these parts should be based on regulatory requirements applicable to the end application.

Both components maintain Active product status and identical Moisture Sensitivity Level (MSL 1 - Unlimited), confirming long-term availability and consistent handling requirements.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W100RGEB replace RCP2512B100RJS3 in existing designs?

A: Yes. Both parts maintain identical resistance value (100 Ohms), power rating (4.6W), package dimensions (2512), and operating temperature range (-65°C ~ 155°C). The ±2% tolerance of RCP2512W100RGEB is tighter than the ±5% tolerance of RCP2512B100RJS3, making it functionally compatible for direct substitution.

Q: What is the significance of the tolerance difference?

A: RCP2512W100RGEB specifies ±2% tolerance while RCP2512B100RJS3 specifies ±5% tolerance. The tighter tolerance of the substitute part provides greater precision in resistance value. Applications requiring specific tolerance bands should confirm compatibility with circuit design specifications.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 2512 (6432 Metric) with 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: What is the difference in RoHS compliance?

A: RCP2512B100RJS3 is RoHS non-compliant while RCP2512W100RGEB is ROHS3 compliant. Selection depends on regulatory requirements for the target market and application. Both parts maintain identical electrical and mechanical specifications.

Q: Are moisture handling requirements the same?

A: Yes. Both components feature Moisture Resistant composition and carry Moisture Sensitivity Level 1 (Unlimited), indicating identical storage and handling requirements with no time-limited shelf life restrictions.
