Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP0505B100RJTP is permissible when the following criteria are met:

• Resistance value matches exactly: 100 Ohms
• Power rating is equal to or greater than: 1.4W
• Package / Case designation is identical: 0505 (1412 Metric)
• Physical dimensions remain within specified limits: 0.055" L x 0.050" W (1.40mm x 1.27mm), Height 0.025" max (0.64mm)
• Composition type is Thick Film
• Temperature Coefficient does not exceed: ±150ppm/°C
• Operating temperature range encompasses or matches: -65°C ~ 155°C
• Moisture Sensitivity Level is 1 (Unlimited)
• Number of terminations: 2

The RCP0505W100RGEB qualifies as a direct substitute based on these parameters. The primary difference is tolerance specification (±2% versus ±5%), which represents an upgrade in precision while maintaining all other electrical and mechanical compatibility requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RCP0505B100RJTP and RCP0505W100RGEB are active production components from Vishay Dale with identical mechanical and thermal specifications. Selection between these parts depends on compliance and tolerance requirements:

The RCP0505B100RJTP is RoHS non-compliant and carries ±5% tolerance specification.

The RCP0505W100RGEB is ROHS3 compliant and carries ±2% tolerance specification, providing improved precision while maintaining full electrical and mechanical compatibility.

For applications requiring RoHS3 compliance or tighter tolerance control, the RCP0505W100RGEB is the appropriate selection. Both parts are suitable for identical PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RCP0505W100RGEB replace RCP0505B100RJTP in existing designs?

A: Yes. Both parts share identical resistance value (100 Ohms), power rating (1.4W), package dimensions (0505 / 1412 Metric), and thermal characteristics. The substitute features improved tolerance (±2% versus ±5%) and RoHS3 compliance.

Q: Are the physical dimensions identical between these parts?

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). PCB footprints and assembly processes remain unchanged.

Q: What is the significance of the tolerance difference?

A: The RCP0505W100RGEB tolerance of ±2% provides tighter resistance value control compared to the ±5% tolerance of the RCP0505B100RJTP. Both tolerances are within the thick film resistor category standard. Selection depends on circuit accuracy requirements.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS3 compliance of the RCP0505W100RGEB does not alter electrical characteristics, thermal performance, or operating temperature range. Compliance status reflects manufacturing process and material composition only.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the RCP0505B100RJTP and RCP0505W100RGEB are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life without moisture bake-out requirements. Both parts carry this classification.
