Substitute Part Grouping Explanation

The RCP2512W75R0GEB qualifies as a direct substitute based on the following criteria:

• Identical resistance value: 75 Ohms
• Identical package / case: 2512 (6432 Metric)
• Identical physical dimensions: 0.250" L x 0.124" W (6.35mm x 3.15mm)
• Identical power rating: 4.6W
• Identical composition: Thick Film
• Identical temperature coefficient: ±150ppm/°C
• Identical operating temperature range: -65°C ~ 155°C
• Identical moisture resistance features
• Identical MSL rating: 1 (Unlimited)
• Identical RoHS compliance: ROHS3 Compliant

The primary difference is tolerance specification: RCP2512W75R0GEB provides ±2% tolerance versus the ±5% tolerance of the main part. This represents an upgrade in precision without any compromise to mechanical or thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both RCP2512B75R0JEC and RCP2512W75R0GEB are active production components from Vishay Dale with full ROHS3 compliance. Selection between these parts depends on tolerance requirements:

• Use RCP2512B75R0JEC when ±5% tolerance meets circuit specifications and cost optimization is prioritized.
• Use RCP2512W75R0GEB when ±2% tolerance is required for improved precision in critical applications.

Both parts are mechanically and thermally interchangeable with identical package dimensions, power handling, and operating ranges. No design modifications are required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W75R0GEB replace RCP2512B75R0JEC in existing designs?

A: Yes. Both parts share identical mechanical dimensions (2512 package), electrical ratings (4.6W, 75 Ohms), and thermal characteristics (-65°C ~ 155°C). The substitute offers improved tolerance (±2% vs ±5%) with no design changes required.

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

A: The tolerance specification differs. RCP2512B75R0JEC provides ±5% tolerance, while RCP2512W75R0GEB provides ±2% tolerance. All other electrical and mechanical parameters are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RCP2512B75R0JEC and RCP2512W75R0GEB are ROHS3 compliant with MSL rating 1 (Unlimited moisture sensitivity level).

Q: Do these parts require different PCB footprints?

A: No. Both parts use the 2512 (6432 Metric) package with identical dimensions: 0.250" L x 0.124" W (6.35mm x 3.15mm). The same PCB footprint accommodates both parts.

Q: What is the temperature coefficient for both parts?

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