Key Parameters

Substitute Part Grouping Explanation

Substitution for the RCP2512W50R0JS6 is determined by strict equivalence in the following 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: Yes (exact match required)

Tolerance may vary within the acceptable range for the application. The substitute part RCP2512W50R0GEB meets all core electrical and mechanical parameters while offering improved tolerance specification (±2% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W50R0GEB serves as a direct substitute for the RCP2512W50R0JS6 based on identical electrical specifications and mechanical compatibility. Both parts maintain the same 50 Ohm resistance, 4.6W power rating, 2512 package footprint, and operating temperature range.

The primary distinction is tolerance specification: RCP2512W50R0GEB provides ±2% tolerance compared to ±5% in the original part. This represents an upgrade in precision without altering circuit compatibility.

RCP2512W50R0GEB additionally achieves ROHS3 compliance, whereas RCP2512W50R0JS6 is RoHS non-compliant. Selection between these parts depends on regulatory and environmental requirements applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W50R0GEB replace RCP2512W50R0JS6 in existing designs?

A: Yes. Both parts share identical resistance value (50 Ohms), power rating (4.6W), package dimensions (2512), and operating temperature range (-65°C ~ 155°C). Mechanical and electrical compatibility is maintained.

Q: What is the difference between these two parts?

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

Q: Are the package dimensions identical?

A: Yes. Both parts use the 2512 (6432 Metric) package 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 footprints are interchangeable.

Q: Does tolerance difference affect circuit performance?

A: Tolerance affects the precision of the resistance value. RCP2512W50R0GEB's ±2% tolerance provides tighter resistance control compared to RCP2512W50R0JS6's ±5% tolerance. Selection depends on circuit accuracy requirements.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
