Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCP0505W100RJEC is determined by the following critical parameters:

• Resistance value: 100 Ohms (exact match required)
• Power rating: 1.4W (exact match required)
• Package type: 0505 (1412 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -65°C ~ 155°C (exact match required)
• Temperature coefficient: ±150ppm/°C (exact match required)
• Moisture resistance: Required
• RoHS compliance: ROHS3 Compliant (exact match required)
• MSL rating: 1 (Unlimited) (exact match required)

The RCP0505W100RGEB qualifies as a substitute part because it maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±2% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

Both RCP0505W100RJEC and RCP0505W100RGEB are active production components with ROHS3 compliance and MSL 1 rating, suitable for applications requiring moisture-resistant thick film resistors in the 0505 package. The RCP0505W100RGEB provides tighter tolerance specification (±2%) compared to the RCP0505W100RJEC (±5%), making it applicable for circuits where improved resistance accuracy is beneficial. Both parts maintain identical electrical performance across the -65°C to 155°C operating range and are mechanically interchangeable in PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can RCP0505W100RGEB replace RCP0505W100RJEC in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package dimensions, operating temperature range, and thermal characteristics. The RCP0505W100RGEB offers improved tolerance (±2% versus ±5%), making it a direct substitute with enhanced accuracy.

Q: Are there any mechanical compatibility concerns?

A: No. 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 (0.025" / 0.64mm). PCB footprints and assembly processes remain unchanged.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both RCP0505W100RJEC and RCP0505W100RGEB are ROHS3 compliant with MSL 1 (Unlimited) rating, suitable for applications requiring moisture-resistant components without special handling.

Q: What is the primary difference between these parts?

A: The tolerance specification differs. RCP0505W100RJEC provides ±5% tolerance, while RCP0505W100RGEB provides ±2% tolerance. All other electrical and mechanical parameters are identical.

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

A: Yes. Both parts are supplied in Tape & Reel (TR) format for automated assembly processes.
