RCP1206W1K00JS2 Equivalent & Substitute Parts

Part Overview

The RCP1206W1K00JS2 is a 1 kOhms ±5% 2.4W chip resistor in 1206 (3216 Metric) package manufactured by Vishay Dale. This thick film, moisture-resistant component operates across -65°C to 155°C and is currently in active production status. Substitute parts are identified to address packaging format preferences, tolerance requirements, or RoHS compliance needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCP1206W1K00JS2 is determined by the following critical parameters:

• Resistance value: 1 kOhms (exact match required)
• Power rating: 2.4W (exact match required)
• Package / Case: 1206 (3216 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)
• Features: Moisture Resistant (exact match required)
• Moisture Sensitivity Level: 1 (exact match required)

The RCP1206W1K00GEB qualifies as a substitute because it maintains all critical electrical and mechanical parameters. Variations in tolerance (±2% vs. ±5%) and packaging format (Cut Tape vs. Tape & Reel) do not affect functional compatibility in applications where the main part is specified.

Engineering Selection Recommendations

The RCP1206W1K00GEB serves as a direct functional substitute for the RCP1206W1K00JS2 in applications requiring the specified electrical and thermal characteristics. Selection between these parts should be based on:

• Packaging format requirements: The main part is supplied in Tape & Reel format, while the substitute is available in Cut Tape format. Choose based on assembly process and quantity requirements.
• RoHS compliance: The substitute part is ROHS3 compliant, whereas the main part is RoHS non-compliant. Applications subject to RoHS regulations should specify the substitute.
• Tolerance specification: The substitute offers improved tolerance (±2%) compared to the main part (±5%). Applications with tighter tolerance requirements benefit from the substitute.

Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility within the 1206 package footprint.

Frequently Asked Questions (FAQ)

Q: Can RCP1206W1K00GEB replace RCP1206W1K00JS2 in existing designs?

A: Yes. Both parts share identical resistance, power rating, package dimensions, operating temperature range, and thermal characteristics. The substitute is mechanically and electrically compatible.

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

A: Tape & Reel packaging is used for high-volume automated assembly, while Cut Tape is suitable for lower volumes or manual assembly. Both formats contain the same component; packaging choice depends on production methodology and order quantity.

Q: Does the tolerance difference affect circuit performance?

A: The RCP1206W1K00GEB offers ±2% tolerance versus ±5% for the main part. In applications where resistance value precision is critical, the substitute provides tighter tolerance. For applications where ±5% tolerance is acceptable, both parts perform identically.

Q: Is RoHS compliance required for my application?

A: RoHS compliance is mandated by regulations in specific markets and industries. The RCP1206W1K00GEB is ROHS3 compliant, while the main part is not. Verify regulatory requirements for your target market before component selection.

Q: Are the physical dimensions identical?

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

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. Both parts can be stored and handled without special desiccant packaging or environmental controls.
