Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP0505W50R0JS6 is valid when the following core parameters remain constant or improve:

• Resistance value: 50 Ohms (exact match required)
• Package / Case: 0505 (1412 Metric) (exact match required)
• Power rating: 1.4W (minimum requirement)
• Composition: Thick Film
• Temperature coefficient: ±150ppm/°C (maximum allowed)
• Operating temperature range: -65°C ~ 155°C (minimum coverage required)
• Moisture resistance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

Tolerance may be tightened (improved) from ±5% to ±2% without affecting functional compatibility. RoHS compliance status may be upgraded from non-compliant to compliant.

Parameter Comparison

Engineering Selection Recommendations

The RCP0505W50R0GEB serves as a direct substitute for the RCP0505W50R0JS6 with the following considerations:

Tolerance Improvement: The substitute part offers ±2% tolerance compared to ±5%, providing tighter resistance value control. This improvement is compatible with applications requiring the original ±5% specification.

Compliance Enhancement: The RCP0505W50R0GEB is ROHS3 compliant, whereas the original part is RoHS non-compliant. Selection of the compliant variant is appropriate for applications subject to RoHS regulations.

Electrical and Mechanical Equivalence: All critical parameters—resistance, power rating, package dimensions, temperature range, and moisture resistance—remain identical between the two parts, ensuring direct functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can RCP0505W50R0GEB replace RCP0505W50R0JS6 in existing designs?

A: Yes. Both parts share identical resistance (50 Ohms), power rating (1.4W), package (0505), temperature range (-65°C ~ 155°C), and moisture resistance specifications. The substitute offers improved tolerance (±2% vs ±5%) and RoHS3 compliance.

Q: What is the significance of the tolerance difference between ±5% and ±2%?

A: Tolerance defines the allowable deviation from the nominal resistance value. The ±2% tolerance of RCP0505W50R0GEB is tighter, meaning resistance values remain closer to 50 Ohms. This is a specification improvement that does not compromise compatibility with designs accepting ±5% tolerance.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0505 (1412 Metric) with identical dimensions of 0.055" L x 0.050" W (1.40mm x 1.27mm) and maximum seated height of 0.025" (0.64mm). PCB footprints and assembly processes remain unchanged.

Q: What does RoHS3 compliance mean for part selection?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations. Selection of RCP0505W50R0GEB is required for applications or markets with RoHS compliance mandates.

Q: Are the temperature coefficients the same?

A: Yes. Both parts have a temperature coefficient of ±150ppm/°C and operate across the identical range of -65°C ~ 155°C.
