Substitute Part Grouping Explanation

Substitution of RCP0505B100RJS2 is valid when the following criteria are met:

• Resistance value remains 100 Ohms
• Package / Case remains 0505 (1412 Metric)
• Power rating remains 1.4W or higher
• Composition remains Thick Film
• Temperature Coefficient remains ±150ppm/°C
• Operating temperature range remains -65°C ~ 155°C or wider
• Moisture resistance feature is maintained
• Tolerance may be equal or tighter (lower tolerance value acceptable)

The RCP0505W100RGEB qualifies as a direct substitute based on these parameters, with the distinction of improved tolerance specification (±2% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

RCP0505W100RGEB serves as a direct substitute for RCP0505B100RJS2 with the following considerations:

The substitute part maintains identical electrical performance across all critical parameters: 100 Ohms resistance, 1.4W power rating, ±150ppm/°C temperature coefficient, and -65°C to 155°C operating range. Physical dimensions and package specifications are identical, ensuring PCB layout compatibility without modification.

The primary distinction is tolerance specification: RCP0505W100RGEB provides ±2% tolerance compared to the ±5% tolerance of the main part. This represents improved accuracy and is suitable for applications requiring tighter resistance values.

RCP0505W100RGEB achieves ROHS3 compliance, whereas RCP0505B100RJS2 is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance.

Both parts maintain identical moisture sensitivity level (MSL 1 - Unlimited) and export classification (EAR99), indicating equivalent handling and logistics requirements.

Frequently Asked Questions (FAQ)

Q: Can RCP0505W100RGEB replace RCP0505B100RJS2 in existing designs?

A: Yes. Both parts share identical resistance value (100 Ohms), power rating (1.4W), package dimensions (0505 / 1412 Metric), and operating temperature range (-65°C to 155°C). The substitute part's tighter tolerance (±2%) is compatible with applications designed for the main part's ±5% tolerance.

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

A: RCP0505B100RJS2 specifies ±5% tolerance, while RCP0505W100RGEB specifies ±2% tolerance. The substitute provides improved resistance accuracy. Both tolerances are within the same performance class for standard applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.055" L x 0.050" W (1.40mm x 1.27mm) with maximum seated height of 0.025" (0.64mm). No PCB layout modifications are required for substitution.

Q: What is the significance of RoHS compliance difference?

A: RCP0505W100RGEB is ROHS3 compliant, while RCP0505B100RJS2 is RoHS non-compliant. If your application or customer requirements mandate RoHS compliance, RCP0505W100RGEB is the appropriate selection.

Q: Are moisture handling requirements the same?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels and storage/handling requirements.

Q: Can these parts be used interchangeably in tape and reel packaging?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging format, maintaining identical handling and assembly compatibility.
