Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCP2512B100RGS2 are qualified based on the following criteria:

• Identical resistance value: 100 Ohms
• Matching tolerance: ±2%
• Equal or greater power rating: 4.6W
• Same package / case: 2512 (6432 Metric)
• Identical composition: Thick Film
• Matching temperature coefficient: ±150ppm/°C
• Equivalent operating temperature range: -65°C ~ 155°C
• Identical features: Moisture Resistant
• Compatible packaging: Tape & Reel (TR)

Parts meeting all these parameters are electrically and mechanically interchangeable and can be used as direct substitutes in the same circuit application without design modification.

Parameter Comparison

Engineering Selection Recommendations

Both the RCP2512B100RGS2 and RCP2512W100RGEB are active production components from Vishay Dale with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status: the RCP2512B100RGS2 is RoHS non-compliant, while the RCP2512W100RGEB is ROHS3 compliant. Selection between these parts should be based on regulatory and procurement requirements specific to the application and end-use market. Both parts are functionally equivalent for circuit performance.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W100RGEB be used as a direct replacement for RCP2512B100RGS2?

A: Yes. Both parts have identical electrical specifications (100 Ohms ±2%, 4.6W), matching temperature coefficients (±150ppm/°C), equivalent operating ranges (-65°C ~ 155°C), and identical mechanical dimensions (2512 package, 0.250" L x 0.124" W). They are functionally interchangeable.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance. RCP2512B100RGS2 is RoHS non-compliant, while RCP2512W100RGEB is ROHS3 compliant. All other electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2512 (6432 Metric) package with dimensions of 0.250" L x 0.124" W (6.35mm x 3.15mm) and maximum seated height of 0.025" (0.64mm). They are mechanically interchangeable on PCB layouts.

Q: Do these parts have the same moisture sensitivity?

A: Yes. Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Can I mix these parts in the same production batch?

A: Both parts are supplied in Tape & Reel (TR) packaging and have identical specifications. Mixing is possible from a functional standpoint, but procurement and compliance documentation should be reviewed based on your specific regulatory requirements.
