Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP1206B100RJS3 is determined by strict equivalence in the following parameters:

• Resistance value: 100 Ohms (exact match required)
• Power rating: 2.4W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±150ppm/°C (exact match required)
• Operating temperature range: -65°C to 155°C (exact match required)
• Moisture resistance: Required feature
• Termination count: 2 (exact match required)

Tolerance may vary within acceptable circuit design margins. RoHS compliance status and packaging format (Tape & Reel vs. Cut Tape) do not affect electrical substitution but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

The RCP1206W100RGEB serves as a direct electrical substitute for the RCP1206B100RJS3. Both components share identical resistance, power rating, package dimensions, thermal characteristics, and moisture resistance properties. The primary differences are tolerance specification and regulatory compliance status.

The RCP1206W100RGEB offers improved tolerance (±2% versus ±5%), which provides tighter resistance accuracy for precision circuit applications. This component is ROHS3 compliant, addressing regulatory requirements in markets where RoHS compliance is mandatory.

Selection between these parts should be based on circuit tolerance requirements and applicable compliance standards. The tighter tolerance of the RCP1206W100RGEB is suitable for applications requiring enhanced accuracy. The RCP1206B100RJS3 remains appropriate for applications where ±5% tolerance is acceptable and RoHS compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can RCP1206W100RGEB replace RCP1206B100RJS3 in existing designs?

A: Yes. Both components are electrically equivalent in all critical parameters: 100 Ohms resistance, 2.4W power rating, 1206 package, thick film composition, and identical thermal characteristics. The ±2% tolerance of the substitute is superior to the ±5% tolerance of the original part.

Q: What is the difference in tolerance between these parts?

A: RCP1206B100RJS3 has ±5% tolerance, while RCP1206W100RGEB has ±2% tolerance. The tighter tolerance of the substitute provides greater resistance accuracy. For circuits designed to accommodate ±5% tolerance, both parts are functionally equivalent.

Q: Are the physical dimensions identical?

A: Yes. Both components are 1206 (3216 Metric) package with identical dimensions: 0.122" L × 0.060" W (3.10mm × 1.52mm) and maximum seated height of 0.025" (0.64mm). They are mechanically interchangeable on PCBs designed for 1206 resistors.

Q: What is the difference in packaging format?

A: RCP1206B100RJS3 is supplied in Tape & Reel (TR) format, while RCP1206W100RGEB is available in Cut Tape (CT) and Digi-Reel® formats. Packaging format affects procurement and assembly processes but does not impact electrical performance or circuit compatibility.

Q: Does RoHS compliance affect circuit performance?

A: No. RoHS compliance is a regulatory and material composition requirement, not an electrical performance specification. Both components meet identical electrical and thermal specifications. RoHS3 compliance of the substitute is relevant only for applications subject to RoHS regulations.

Q: Are both components suitable for the full operating temperature range?

A: Yes. Both RCP1206B100RJS3 and RCP1206W100RGEB operate across -65°C to 155°C with identical ±150ppm/°C temperature coefficient. They are suitable for identical thermal environments.
