RCP1206B100RJEB Equivalent & Substitute Parts

Part Overview

The RCP1206B100RJEB is a 100 Ohms ±5% 2.4W chip resistor in 1206 (3216 Metric) package manufactured by Vishay Dale. This thick film, moisture-resistant component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Alternative parts may be required due to inventory constraints, packaging format preferences, or tolerance specifications for specific circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP1206B100RJEB is determined by the following critical parameters:

Resistance Value: Must be 100 Ohms
Package / Case: Must be 1206 (3216 Metric)
Power Rating: Must be 2.4W minimum
Composition: Thick Film
Temperature Coefficient: ±150ppm/°C
Operating Temperature Range: -65°C ~ 155°C
RoHS Compliance: ROHS3 Compliant
Moisture Sensitivity Level: MSL 1

The substitute part RCP1206W100RGEB meets all critical parameters with the exception of tolerance specification, which is tightened to ±2% compared to the original ±5%. This represents an upgrade in tolerance performance while maintaining identical electrical and mechanical characteristics across all other parameters.

Engineering Selection Recommendations

Both RCP1206B100RJEB and RCP1206W100RGEB are Active product status components manufactured by Vishay Dale with ROHS3 compliance certification. The RCP1206W100RGEB provides improved tolerance performance at ±2% versus ±5%, making it suitable for applications requiring tighter resistance value control. Both components maintain identical thermal characteristics, package dimensions, and moisture resistance properties. Selection between these parts depends on circuit tolerance requirements and packaging format availability (Tape & Reel versus Cut Tape & Digi-Reel).

Frequently Asked Questions (FAQ)

Q: Can RCP1206W100RGEB replace RCP1206B100RJEB in all applications?

A: Yes, provided the circuit design accommodates the tighter ±2% tolerance specification. The substitute part meets or exceeds all electrical and mechanical parameters of the original component.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components are packaged in 1206 (3216 Metric) case with identical length (0.122" / 3.10mm), width (0.060" / 1.52mm), and maximum seated height (0.025" / 0.64mm).

Q: What is the difference in packaging format?

A: RCP1206B100RJEB is supplied in Tape & Reel (TR) format, while RCP1206W100RGEB is available in Cut Tape (CT) & Digi-Reel format. Both formats are standard for 1206 SMD components and compatible with automated assembly equipment.

Q: Do both parts have the same temperature operating range?

A: Yes. Both components operate across -65°C to 155°C with identical temperature coefficient of ±150ppm/°C.

Q: Are both parts RoHS compliant?

A: Yes. Both RCP1206B100RJEB and RCP1206W100RGEB are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.
