Key Parameters

Substitute Part Grouping Explanation

The RCP0505W100RGEB qualifies as a direct substitute based on the following criteria:

Matching parameters: Identical resistance value (100 Ohms), identical power rating (1.4W), identical package (0505/1412 Metric), identical composition (thick film), identical temperature coefficient (±150ppm/°C), identical operating temperature range (-65°C ~ 155°C), identical MSL rating (1), and identical RoHS compliance (ROHS3).

Differing parameter: Tolerance specification changes from ±5% to ±2%, representing an upgrade in accuracy. This tighter tolerance is electrically compatible with applications designed for the original ±5% specification.

The substitute maintains all mechanical and thermal characteristics, ensuring PCB layout compatibility and thermal performance equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both RCP0505B100RJED and RCP0505W100RGEB are active production components with ROHS3 compliance and MSL 1 ratings. The RCP0505W100RGEB provides improved tolerance performance (±2% versus ±5%) while maintaining identical electrical and mechanical specifications. Selection between these parts depends on application tolerance requirements and inventory availability. Both components are suitable for direct substitution in existing designs without PCB modifications.

Frequently Asked Questions (FAQ)

Q: Can RCP0505W100RGEB replace RCP0505B100RJED in existing designs?

A: Yes. Both parts share identical resistance, power rating, package dimensions, temperature range, and thermal characteristics. The substitute features tighter tolerance (±2% versus ±5%), which is compatible with applications designed for the original specification.

Q: Are there mechanical compatibility concerns?

A: No. Both components use the 0505 (1412 Metric) package with identical dimensions (0.055" L x 0.050" W, 1.40mm x 1.27mm) and maximum seated height (0.025" / 0.64mm). PCB footprints and assembly processes remain unchanged.

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

A: RCP0505B100RJED specifies ±5% tolerance, while RCP0505W100RGEB specifies ±2% tolerance. The tighter tolerance of the substitute provides improved accuracy for precision circuit applications.

Q: Are both parts RoHS compliant?

A: Yes. Both RCP0505B100RJED and RCP0505W100RGEB are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably in production?

A: Yes, provided application tolerance requirements are met. The substitute's ±2% tolerance satisfies any design specification calling for ±5% or tighter tolerance.
