Substitute Part Grouping Explanation

Substitution of the RCP2512B75R0JS3 is determined by strict equivalence in the following critical 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)
• Features: Moisture Resistant (exact match required)
• Number of Terminations: 2 (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Tolerance may vary within acceptable design margins. RoHS compliance status and packaging format (Tape & Reel) do not restrict substitution eligibility but may influence procurement decisions based on regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W75R0GEB serves as a direct substitute for the RCP2512B75R0JS3 with the following considerations:

Tolerance improvement: The substitute part offers ±2% tolerance compared to ±5% tolerance of the original part. This tighter tolerance specification provides enhanced precision for applications requiring stricter resistance value control.

Compliance upgrade: The RCP2512W75R0GEB is ROHS3 compliant, whereas the RCP2512B75R0JS3 is RoHS non-compliant. Selection of the substitute part satisfies regulatory requirements for RoHS-restricted applications.

All other electrical and mechanical parameters remain identical, ensuring direct functional equivalence in circuit applications. Both parts maintain Active product status and are available in Tape & Reel packaging format.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W75R0GEB replace RCP2512B75R0JS3 in existing designs?

A: Yes. Both parts share identical resistance value (75 Ohms), power rating (4.6W), package type (2512), composition (thick film), temperature coefficient (±150ppm/°C), operating temperature range (-65°C ~ 155°C), and moisture resistance features. The substitute part features improved tolerance (±2% vs ±5%) and ROHS3 compliance.

Q: What is the significance of tolerance difference between these parts?

A: The RCP2512B75R0JS3 has ±5% tolerance, while RCP2512W75R0GEB has ±2% tolerance. Tighter tolerance in the substitute part means the actual resistance value will be closer to the nominal 75 Ohm specification. Applications requiring precise resistance values benefit from the substitute part's improved tolerance.

Q: Are the physical 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 layout and footprint compatibility are maintained.

Q: What does ROHS3 compliance mean for the substitute part?

A: ROHS3 compliance indicates the RCP2512W75R0GEB meets Restriction of Hazardous Substances Directive requirements. The original RCP2512B75R0JS3 is RoHS non-compliant. Selection of the substitute part is necessary for applications subject to RoHS regulatory requirements.

Q: Are both parts available in the same packaging format?

A: Yes. Both the RCP2512B75R0JS3 and RCP2512W75R0GEB are supplied in Tape & Reel (TR) packaging format, ensuring compatibility with automated assembly processes.
