Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCP1206W1K00JS3 is determined by the following critical parameters:

• Resistance Value: Must be 1 kOhms
• Package / Case: Must be 1206 (3216 Metric)
• Power Rating: Must be 2.4W minimum
• Composition: Must be Thick Film
• Temperature Coefficient: Must be ±150ppm/°C
• Operating Temperature Range: Must be -65°C ~ 155°C or wider
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The RCP1206W1K00GEB qualifies as a substitute because it maintains all critical electrical and mechanical parameters while offering improved tolerance (±2% versus ±5%) and alternative packaging (Cut Tape versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

Both the RCP1206W1K00JS3 and RCP1206W1K00GEB are active production components from Vishay Dale's RCP series. Selection between these parts should be based on the following criteria:

RCP1206W1K00JS3 is appropriate for applications where ±5% tolerance is acceptable and Tape & Reel packaging is required for automated assembly processes. This part is suitable for cost-sensitive applications where tighter tolerance is not a design requirement.

RCP1206W1K00GEB is appropriate for applications requiring improved tolerance performance (±2%) and is compliant with ROHS3 regulations. This part is suitable for designs where environmental compliance is mandatory or where tighter resistance tolerance improves circuit performance. Cut Tape packaging is suitable for lower-volume production or manual assembly workflows.

Both parts share identical electrical performance characteristics, physical dimensions, and thermal specifications, ensuring direct functional interchangeability within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can RCP1206W1K00GEB replace RCP1206W1K00JS3 in existing designs?

A: Yes. Both parts maintain identical resistance value (1 kOhms), power rating (2.4W), package dimensions (1206), and operating temperature range (-65°C ~ 155°C). The RCP1206W1K00GEB offers improved tolerance (±2% versus ±5%), making it a direct functional substitute.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is used for high-volume automated assembly with pick-and-place equipment. Cut Tape (CT) packaging is supplied as individual components on carrier tape, suitable for lower-volume production or manual assembly. Both formats contain the same component.

Q: Does tolerance difference affect circuit performance?

A: Tolerance determines the maximum deviation from the nominal resistance value. RCP1206W1K00JS3 (±5%) allows resistance between 950 Ohms and 1050 Ohms. RCP1206W1K00GEB (±2%) allows resistance between 980 Ohms and 1020 Ohms. Selection depends on circuit sensitivity to resistance variation.

Q: What does RoHS3 compliance mean?

A: ROHS3 compliance indicates the component meets Restriction of Hazardous Substances Directive requirements, restricting use of specific hazardous materials. RCP1206W1K00GEB is ROHS3 compliant; RCP1206W1K00JS3 is not. This distinction is relevant for applications subject to environmental regulations.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 1206 (3216 Metric) package with dimensions of 0.122" L x 0.060" W (3.10mm x 1.52mm) and maximum seated height of 0.025" (0.64mm), ensuring identical PCB footprint compatibility.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture exposure precautions. Both parts have MSL 1 rating, meaning they do not require special moisture control during storage or handling.
