RCP0505W100RGEC Equivalent & Substitute Parts

Part Overview

The RCP0505W100RGEC is a 100 Ohms ±2% 1.4W chip resistor in 0505 (1412 Metric) package manufactured by Vishay Dale. This moisture-resistant thick film resistor is designed for surface mount applications requiring stable performance across industrial temperature ranges. The part is currently active in production with full RoHS3 compliance and MSL Level 1 rating, making it suitable for high-reliability applications without moisture sensitivity constraints.

Substitute parts are identified when electrical specifications, mechanical dimensions, and environmental ratings remain identical across the product line, ensuring direct interchangeability without circuit redesign or performance degradation.

Substitute Part Grouping Explanation

The RCP0505W100RGEB qualifies as a direct substitute for RCP0505W100RGEC based on identical electrical and mechanical specifications. Substitution is valid when the following parameters match exactly:

• Resistance value: 100 Ohms
• Tolerance: ±2%
• Power rating: 1.4W
• Package designation: 0505 (1412 Metric)
• Physical dimensions: 0.055" L x 0.050" W (1.40mm x 1.27mm)
• Height - Seated (Max): 0.025" (0.64mm)
• Composition: Thick Film
• Temperature coefficient: ±150ppm/°C
• Operating temperature range: -65°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Both parts belong to the RCP series and maintain identical environmental ratings and termination specifications (2 terminations).

Parameter Comparison

Engineering Selection Recommendations

Both RCP0505W100RGEC and RCP0505W100RGEB are active production parts with full ROHS3 compliance and MSL Level 1 certification. Selection between these parts is based on inventory availability and supply chain considerations rather than technical performance differences. The RCP0505W100RGEB currently maintains higher inventory levels (1644 Pcs vs. 732 Pcs), making it a viable alternative when primary part availability is constrained. Both parts are suitable for applications requiring moisture-resistant thick film resistors in compact 0505 packages with industrial temperature operating ranges.

Frequently Asked Questions (FAQ)

Q: Can RCP0505W100RGEB be used as a direct replacement for RCP0505W100RGEC in existing designs?

A: Yes. Both parts share identical electrical specifications (100 Ohms ±2%, 1.4W), mechanical dimensions (0505 package, 1.40mm x 1.27mm), and environmental ratings (-65°C ~ 155°C operating range, MSL Level 1). No circuit modifications or re-qualification are required.

Q: Are there differences in moisture sensitivity between these parts?

A: No. Both parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.

Q: Do both parts meet RoHS requirements?

A: Yes. Both RCP0505W100RGEC and RCP0505W100RGEB are ROHS3 compliant.

Q: What determines substitutability for RCP series 0505 resistors?

A: Substitutability is determined by matching resistance value, tolerance, power rating, package type, physical dimensions, temperature coefficient, operating temperature range, and environmental certifications. All these parameters must be identical for direct substitution.

Q: Are there packaging differences between these parts?

A: No. Both parts are supplied in Tape & Reel (TR) packaging in the 0505 (1412 Metric) format with identical physical dimensions and termination specifications.
