Key Parameters

Substitute Part Grouping Explanation

Substitution for the RCP2512W100RJS6 is determined by strict equivalence in the following parameters:

• Resistance value: 100 Ohms (exact match required)
• Power rating: 4.6W (exact match required)
• Package / Case: 2512 (6432 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 feature: Present (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

Tolerance may vary within the acceptable range for the application. The substitute part RCP2512W100RGEB meets all these criteria with an improved tolerance specification of ±2%.

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W100RGEB serves as a direct substitute for the RCP2512W100RJS6 with the following considerations:

Electrical equivalence is maintained across all critical parameters: resistance value, power rating, temperature coefficient, and operating temperature range. The substitute part offers improved tolerance specification (±2% versus ±5%), which provides tighter resistance accuracy without compromising circuit compatibility.

The primary distinction is RoHS compliance status. The RCP2512W100RGEB is ROHS3 compliant, while the RCP2512W100RJS6 is RoHS non-compliant. This difference is significant for applications subject to RoHS regulatory requirements.

Both parts share identical mechanical specifications, package dimensions, and moisture sensitivity characteristics, ensuring direct PCB layout compatibility and assembly process equivalence.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W100RGEB replace RCP2512W100RJS6 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. The substitute maintains the same 100 Ohms resistance, 4.6W power rating, 2512 package, and operating temperature range. The improved ±2% tolerance of the substitute part is compatible with applications designed for the ±5% tolerance specification.

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

A: The main part RCP2512W100RJS6 has ±5% tolerance, while the substitute RCP2512W100RGEB has ±2% tolerance. The tighter tolerance of the substitute part provides improved resistance accuracy and is backward-compatible with designs specified for ±5% tolerance.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 2512 (6432 Metric) package with identical dimensions of 0.250" L x 0.124" W (6.35mm x 3.15mm) and maximum seated height of 0.025" (0.64mm). PCB footprints and assembly processes are directly interchangeable.

Q: What is the significance of RoHS compliance difference?

A: The RCP2512W100RGEB is ROHS3 compliant while the RCP2512W100RJS6 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the substitute part is the appropriate selection.

Q: Are the moisture sensitivity levels the same?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating equivalent moisture handling and storage requirements.

Q: Do both parts have the same temperature coefficient?

A: Yes. Both parts have a temperature coefficient of ±150ppm/°C and operate across the identical temperature range of -65°C to 155°C.
