RCP0505W100RJS3 Equivalent & Substitute Parts

Part Overview

The RCP0505W100RJS3 is a 100 Ohms ±5% 1.4W chip resistor in 0505 (1412 Metric) package manufactured by Vishay Dale. This thick film, moisture-resistant component operates across -65°C to 155°C and is classified as Active product status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained while potentially improving tolerance specifications or compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP0505W100RJS3 is determined by maintaining the following critical parameters:

• Resistance value: 100 Ohms (exact match required)
• Power rating: 1.4W (minimum requirement)
• Package / Case: 0505 (1412 Metric) (mechanical and thermal compatibility)
• Composition: Thick Film (electrical performance characteristics)
• Temperature Coefficient: ±150ppm/°C (thermal stability)
• Operating Temperature Range: -65°C ~ 155°C (environmental compatibility)
• Number of Terminations: 2 (circuit interface requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

Tolerance may vary within acceptable design margins. RoHS compliance status and inventory availability do not affect electrical or mechanical substitutability but are noted for procurement considerations.

Parameter Comparison

Engineering Selection Recommendations

The RCP0505W100RGEB serves as a direct electrical and mechanical substitute for the RCP0505W100RJS3. Both components are manufactured by Vishay Dale and maintain identical resistance, power rating, package dimensions, and thermal characteristics. The substitute part offers improved tolerance specification (±2% versus ±5%), which provides tighter resistance accuracy without compromising any electrical or mechanical parameter.

The RCP0505W100RGEB achieves ROHS3 compliance, whereas the main part is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements. Both parts maintain Active product status and identical moisture sensitivity classification, ensuring equivalent handling and storage requirements.

Selection between these parts depends on regulatory compliance requirements and tolerance precision needs for the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can RCP0505W100RGEB replace RCP0505W100RJS3 in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package dimensions, thermal coefficient, and operating temperature range. The substitute part is mechanically and electrically compatible for direct board-level replacement.

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

A: The main part RCP0505W100RJS3 has ±5% tolerance, while the substitute RCP0505W100RGEB has ±2% tolerance. The tighter tolerance of the substitute part does not create incompatibility; it provides improved resistance accuracy.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 0505 (1412 Metric) package with identical length (0.055" / 1.40mm), width (0.050" / 1.27mm), and maximum seated height (0.025" / 0.64mm). They are mechanically interchangeable on PCBs designed for either part.

Q: Does RoHS compliance affect substitutability?

A: RoHS compliance status does not affect electrical or mechanical substitutability. The RCP0505W100RGEB's ROHS3 compliance is an additional benefit for applications requiring regulatory adherence but does not impact circuit performance or physical compatibility.

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

A: Yes. Both the RCP0505W100RJS3 and RCP0505W100RGEB are supplied in Tape & Reel (TR) packaging for automated assembly processes.

Q: What is the moisture sensitivity classification for both parts?

A: Both parts are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for handling, storage, or assembly.
