Key Parameters

Substitute Part Grouping Explanation

Substitution of RCP2512W50R0JS3 is determined by the following critical parameters that must remain constant:

• Resistance value: 50 Ohms (exact match required)
• Power rating: 4.6W (exact match required)
• Package / Case: 2512 (6432 Metric) (exact match required)
• Physical dimensions: 0.250" L x 0.124" W (6.35mm x 3.15mm) (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)
• Number of Terminations: 2 (exact match required)

Parameters that may vary in substitute parts:

• Tolerance: May be tighter (lower value acceptable)
• RoHS Status: May be upgraded to compliant version
• Moisture Sensitivity Level: Remains MSL 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

RCP2512W50R0GEB is a direct substitute for RCP2512W50R0JS3 with the following considerations:

The substitute part maintains identical electrical performance, mechanical compatibility, and thermal characteristics. The primary difference is tolerance specification: RCP2512W50R0GEB provides ±2% tolerance compared to ±5% in the original part, representing improved precision without any performance degradation.

RCP2512W50R0GEB achieves ROHS3 compliance, whereas RCP2512W50R0JS3 is RoHS non-compliant. This upgrade is significant for applications subject to RoHS regulatory requirements or environmental compliance mandates.

Both parts share identical package dimensions, thermal coefficients, operating temperature ranges, and moisture resistance characteristics, ensuring direct PCB-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W50R0GEB replace RCP2512W50R0JS3 in existing designs?

A: Yes. Both parts are identical in resistance value (50 Ohms), power rating (4.6W), package type (2512), physical dimensions, thermal characteristics, and operating temperature range. The substitute part is mechanically and electrically compatible without PCB redesign.

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 non-compliant). The substitute provides tighter tolerance and regulatory compliance.

Q: Are the package dimensions identical?

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

Q: Does the tighter tolerance of RCP2512W50R0GEB affect circuit performance?

A: The ±2% tolerance of RCP2512W50R0GEB is more precise than the ±5% tolerance of RCP2512W50R0JS3. This represents an improvement in resistance accuracy and does not negatively affect circuit performance.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both RCP2512W50R0JS3 and RCP2512W50R0GEB are supplied in Tape & Reel (TR) packaging format.

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

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited moisture resistance and no special storage or handling requirements.
