Substitute Part Grouping Explanation

Substitution eligibility for the RCP2512B100RGEA is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 Ohms
• Tolerance: ±2%
• Power rating: 4.6W
• Package designation: 2512 (6432 Metric)
• Composition type: Thick Film
• Temperature coefficient: ±150ppm/°C
• Operating temperature range: -65°C ~ 155°C
• Moisture resistance feature
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The identified substitute RCP2512W100RGEB meets all these criteria. Variations in packaging format (Tape & Reel) and inventory levels do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both RCP2512B100RGEA and RCP2512W100RGEB are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts may be based on:

• Packaging format availability (both supplied in Tape & Reel)
• Current inventory levels (RCP2512B100RGEA: 1109 units; RCP2512W100RGEB: 1011 units)
• Supply chain lead times
• Procurement preferences

Both parts satisfy ROHS3 compliance requirements and MSL 1 rating, making them suitable for applications without moisture sensitivity constraints. No performance differentiation exists between these variants.

Frequently Asked Questions (FAQ)

Q: Are RCP2512B100RGEA and RCP2512W100RGEB electrically identical?

A: Yes. Both parts have identical resistance (100 Ohms), tolerance (±2%), power rating (4.6W), temperature coefficient (±150ppm/°C), and operating temperature range (-65°C ~ 155°C).

Q: Can these parts be used interchangeably on PCBs?

A: Yes. Both parts share identical package designation (2512 / 6432 Metric), physical dimensions (0.250" L x 0.124" W), and termination count (2), ensuring mechanical and electrical interchangeability in circuit designs.

Q: What is the significance of the part number suffix (B vs. W)?

A: The suffix indicates manufacturing or packaging variants within the Vishay Dale RCP series. Both variants maintain identical performance specifications and compliance certifications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RCP2512B100RGEA and RCP2512W100RGEB are ROHS3 compliant with MSL rating 1 (Unlimited moisture sensitivity level).

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current availability, supply chain considerations, and procurement lead times, as no technical differentiation exists between them.
