RCP0505B100RJEC Equivalent & Substitute Parts

Part Overview

The RCP0505B100RJEC 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 ROHS3 compliant with MSL 1 rating. The part is currently active in production with 1151 pieces available in stock.

Substitute parts are identified when electrical specifications (resistance value, power rating, package) and environmental ratings remain equivalent or superior, enabling direct replacement in circuit applications without design modification.

Substitute Part Grouping Explanation

Substitution eligibility for the RCP0505B100RJEC is determined by the following criteria:

• Identical resistance value: 100 Ohms
• Equal or superior tolerance: ±5% or better (±2% qualifies as superior)
• Equal or greater power rating: 1.4W minimum
• Identical package: 0505 (1412 Metric)
• Identical composition: Thick Film
• Equal or wider operating temperature range: -65°C ~ 155°C minimum
• Equal or superior temperature coefficient: ±150ppm/°C or better
• Equal or superior environmental compliance: ROHS3 Compliant minimum
• Equal or superior moisture sensitivity: MSL 1 minimum

The RCP0505W100RGEB meets all substitution criteria with an upgrade in tolerance specification (±2% versus ±5%), maintaining all other electrical and environmental parameters.

Parameter Comparison

Engineering Selection Recommendations

Both RCP0505B100RJEC 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 performance, power rating, and thermal characteristics. Selection between these parts depends on circuit tolerance requirements: the RCP0505B100RJEC is suitable for applications tolerating ±5% resistance variation, while RCP0505W100RGEB is appropriate for designs requiring tighter tolerance control at ±2%.

Frequently Asked Questions (FAQ)

Q: Can RCP0505W100RGEB replace RCP0505B100RJEC in existing designs?

A: Yes. The RCP0505W100RGEB is a direct substitute with superior tolerance specification. All electrical parameters, package dimensions, thermal ratings, and environmental compliance are identical or equivalent.

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

A: The tolerance specification differs: RCP0505B100RJEC is ±5% while RCP0505W100RGEB is ±2%. All other parameters including resistance value, power rating, package, operating temperature range, and compliance certifications are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts 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 of 0.025" (0.64mm).

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and operate across -65°C to 155°C with ±150ppm/°C temperature coefficient.

Q: Which part should be selected for new designs?

A: Selection is based on circuit tolerance requirements. For applications requiring ±5% tolerance, either part is suitable. For designs requiring ±2% tolerance, RCP0505W100RGEB is the appropriate selection.
