RCP0505B100RJS3 Equivalent & Substitute Parts Reference

Part Overview

The Vishay Dale RCP0505B100RJS3 is a 100 Ohm ±5% tolerance, 1.4W chip resistor in a 0505 (1412 Metric) SMD package, featuring moisture-resistant thick film construction. With an active status and offered in tape & reel packaging, this part is used in surface-mount applications requiring 100 Ohms resistance and robust power handling. Finding alternative models is necessary due to factors such as compliance requirements (RoHS non-compliance of the main part), supply chain redundancy, or seeking improved performance parameters.

Substitute Part Grouping Explanation

Substitute parts for RCP0505B100RJS3 are determined strictly by matching or exceeding the following key parameters: resistance value (100 Ohms), power rating (1.4W), tolerance, temperature coefficient, operating temperature range, thick film composition, moisture resistance feature, package size (0505 / 1412 Metric), number of terminations, and moisture sensitivity level. Only parts meeting these criteria are considered suitable substitutes.

Engineering Selection Recommendations

The main part, RCP0505B100RJS3, is RoHS non-compliant. The substitute part, RCP0505W100RGEB, is ROHS3 compliant. When RoHS compliance is mandated, RCP0505W100RGEB is preferable. Both parts have an active status and align on critical electrical, mechanical, and dimensional parameters.

Frequently Asked Questions (FAQ)

Q: What are the essential criteria for substituting RCP0505B100RJS3?
A: Equivalent resistance, power rating, tolerance (or better), temperature coefficient, composition, moisture resistance, identical package/case and dimensions, and number of terminations are the strict substitution criteria.

Q: Is the RCP0505W100RGEB a direct mechanical fit?
A: Both parts share the same 0505 (1412 Metric) SMD package, identical dimensions, and termination scheme, ensuring direct compatibility in the same footprint.

Q: Do substitute parts differ in compliance status?
A: Yes. RCP0505B100RJS3 is RoHS non-compliant, while RCP0505W100RGEB is ROHS3 compliant. This difference determines suitability for applications requiring RoHS-compliant components.

Q: Are there differences in electrical performance?
A: Both parts have the same resistance, power rating, temperature coefficient, and features; RCP0505W100RGEB provides a tighter tolerance (±2%).

Q: Can the substitute part be used in moisture-prone environments?
A: Both the main and substitute part feature moisture-resistant construction as specified.
