Key Parameters

Substitute Part Grouping Explanation

Substitution for the RCP0505B100RJEB is determined by the following criteria:

Resistance value must remain 100 Ohms. Tolerance may be tighter (lower percentage) without affecting circuit functionality. Power rating must equal or exceed 1.4W. Package and case dimensions must be identical (0505 / 1412 Metric) to ensure mechanical and electrical compatibility on the PCB. Composition, temperature coefficient, and operating temperature range must match or exceed the original specifications. RoHS compliance and MSL rating must be maintained or improved.

The RCP0505W100RGEB qualifies as a direct substitute because it maintains all critical parameters while offering improved tolerance (±2% versus ±5%), providing enhanced precision for the same 100 Ohm, 1.4W application in the 0505 package.

Parameter Comparison

Engineering Selection Recommendations

Both the RCP0505B100RJEB and RCP0505W100RGEB are active production components from Vishay Dale with ROHS3 compliance and MSL 1 rating. The RCP0505W100RGEB provides improved tolerance specification (±2%) while maintaining identical electrical power rating, thermal characteristics, and mechanical package dimensions. Selection between these parts depends on circuit tolerance requirements. The RCP0505W100RGEB is suitable for applications requiring tighter resistance tolerance. Both components are qualified for the same operating temperature range and environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can RCP0505W100RGEB replace RCP0505B100RJEB in existing designs?

A: Yes. Both parts share identical resistance value (100 Ohms), power rating (1.4W), package (0505), thermal coefficient (±150ppm/°C), and operating temperature range (-65°C ~ 155°C). The substitute offers tighter tolerance (±2% versus ±5%), which is compatible with circuits designed for the original part.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. RCP0505B100RJEB has ±5% tolerance, while RCP0505W100RGEB has ±2% tolerance. All other electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 0505 (1412 Metric) package with dimensions of 0.055" L x 0.050" W (1.40mm x 1.27mm) and maximum seated height of 0.025" (0.64mm). PCB footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RCP0505B100RJEB and RCP0505W100RGEB are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Which part should be selected for precision-critical applications?

A: The RCP0505W100RGEB with ±2% tolerance is appropriate for applications requiring tighter resistance tolerance control.
