Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCP2512W50R0JS2 is determined by the following critical parameters:

• Resistance Value: Must be 50 Ohms
• Package / Case: Must be 2512 (6432 Metric)
• Power Rating: Must be 4.6W
• Composition: Must be Thick Film
• Temperature Coefficient: Must be ±150ppm/°C
• Operating Temperature Range: Must be -65°C ~ 155°C
• Features: Must include Moisture Resistant
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The RCP2512W50R0GEB qualifies as a direct substitute. While it features improved tolerance (±2% versus ±5%), all other electrical and mechanical parameters remain identical, and it maintains the same package footprint and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

RCP2512W50R0JS2 is suitable for applications where ±5% tolerance meets circuit requirements and RoHS non-compliance is acceptable for the intended market or application.

RCP2512W50R0GEB is the preferred substitute when ROHS3 compliance is mandated or when tighter tolerance (±2%) improves circuit performance. Both parts maintain identical thermal performance, package footprint, and moisture resistance characteristics, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W50R0GEB replace RCP2512W50R0JS2 in existing designs?

A: Yes. Both parts share identical package dimensions (2512), power rating (4.6W), temperature range (-65°C ~ 155°C), and thermal coefficient (±150ppm/°C). The RCP2512W50R0GEB features improved tolerance (±2% vs ±5%) and ROHS3 compliance, making it a direct substitute with no PCB layout changes required.

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

A: The RCP2512W50R0GEB offers tighter tolerance (±2%) compared to the RCP2512W50R0JS2 (±5%), and includes ROHS3 compliance certification. All other electrical and mechanical specifications are identical.

Q: Are there any package or footprint differences?

A: No. Both parts 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). They are footprint-compatible.

Q: Which part should I select for new designs?

A: Selection depends on compliance requirements and tolerance specifications. If ROHS3 compliance is required, use RCP2512W50R0GEB. If tighter tolerance improves circuit performance, RCP2512W50R0GEB is preferred. Otherwise, either part is functionally equivalent.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling precautions are required during storage or assembly.
