Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP2512B50R0JS2 is based on strict equivalence of the following critical parameters:

• Resistance value: 50 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 Resistance: Required feature (exact match required)

Tolerance specifications may vary within acceptable engineering margins. The substitute part RCP2512W50R0GEB meets all critical electrical and mechanical parameters while offering improved tolerance performance (±2% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W50R0GEB serves as a direct electrical and mechanical substitute for the RCP2512B50R0JS2. Both components share identical resistance, power rating, package dimensions, and thermal characteristics. The primary distinction is tolerance specification (±2% versus ±5%) and regulatory compliance status.

Selection of RCP2512W50R0GEB is appropriate when ROHS3 compliance is required or when tighter tolerance specifications (±2%) provide design margin benefits. The RCP2512B50R0JS2 remains suitable for applications where RoHS non-compliance is acceptable and ±5% tolerance meets circuit requirements.

Both components are Active products with equivalent availability and identical thermal performance across the -65°C to 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W50R0GEB replace RCP2512B50R0JS2 in existing designs?

A: Yes. Both components are electrically and mechanically equivalent. The RCP2512W50R0GEB offers improved tolerance (±2% versus ±5%) and ROHS3 compliance. No PCB layout or footprint modifications are required.

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

A: The RCP2512W50R0GEB provides tighter tolerance (±2%) compared to the RCP2512B50R0JS2 (±5%), and meets ROHS3 compliance requirements. All other electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical?

A: Yes. Both components use the 2512 (6432 Metric) package with identical dimensions: 0.250" L x 0.124" W (6.35mm x 3.15mm) and maximum seated height of 0.025" (0.64mm).

Q: Do both parts have the same operating temperature range?

A: Yes. Both the RCP2512B50R0JS2 and RCP2512W50R0GEB operate across -65°C to 155°C with identical temperature coefficient of ±150ppm/°C.

Q: What is the moisture sensitivity level for both parts?

A: Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements and tolerance specifications. For ROHS3-compliant applications or designs requiring ±2% tolerance, use RCP2512W50R0GEB. For applications where RoHS non-compliance is acceptable and ±5% tolerance is sufficient, either part is suitable.
