Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP2512B75R0JS2 is determined by strict equivalence in the following parameters:

• Resistance value: 75 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)
• Temperature Coefficient: ±150ppm/°C (exact match required)
• Operating Temperature Range: -65°C ~ 155°C (exact match required)
• Moisture Resistance: Required feature (exact match required)

Tolerance and RoHS compliance status are permitted to vary within substitute relationships, as these parameters do not affect mechanical or thermal compatibility. The identified substitute part RCP2512W75R0GEB maintains all core electrical and mechanical specifications while offering improved tolerance (±2% versus ±5%) and enhanced RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W75R0GEB serves as a direct substitute for the RCP2512B75R0JS2 in applications where improved tolerance specification or RoHS3 compliance is required. Both components maintain identical electrical performance characteristics, thermal behavior, and mechanical footprint compatibility. The RCP2512W75R0GEB offers tighter tolerance (±2% versus ±5%), which may be beneficial in precision circuit applications. Additionally, the RCP2512W75R0GEB carries ROHS3 compliance certification, whereas the RCP2512B75R0JS2 is RoHS non-compliant. Component selection should be based on specific application requirements regarding tolerance specification and regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W75R0GEB replace RCP2512B75R0JS2 in existing designs?

A: Yes. Both components share identical resistance value (75 Ohms), power rating (4.6W), package dimensions (2512 / 6432 Metric), thermal characteristics (±150ppm/°C, -65°C ~ 155°C), and moisture resistance features. Mechanical and electrical compatibility is confirmed.

Q: What is the primary difference between these two parts?

A: The RCP2512W75R0GEB provides improved tolerance specification (±2% versus ±5%) and carries ROHS3 compliance certification, whereas the RCP2512B75R0JS2 is RoHS non-compliant.

Q: Are the physical dimensions identical?

A: Yes. Both components measure 0.250" L x 0.124" W (6.35mm x 3.15mm) with maximum seated height of 0.025" (0.64mm). PCB footprint compatibility is confirmed.

Q: Does tolerance difference affect circuit performance?

A: Tolerance specification determines the maximum resistance deviation from the nominal 75 Ohm value. The RCP2512W75R0GEB tolerance of ±2% provides tighter resistance accuracy compared to the ±5% tolerance of RCP2512B75R0JS2. Selection depends on circuit precision requirements.

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

A: Yes. Both RCP2512B75R0JS2 and RCP2512W75R0GEB are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
