RCP2512W100RJS2 Equivalent & Substitute Parts

Part Overview

The RCP2512W100RJS2 is a 100 Ohms ±5% 4.6W chip resistor in 2512 (6432 Metric) package manufactured by Vishay Dale. This thick film, moisture-resistant component operates across -65°C to 155°C and is classified as Active product status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required, particularly when enhanced tolerance specifications or improved compliance certifications are necessary for system requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP2512W100RJS2 is based on strict equivalence of the following parameters:

• Resistance value: 100 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 Resistant feature (required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Tolerance may vary within acceptable design margins. Compliance certifications and product status are secondary selection criteria that do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W100RGEB serves as a direct substitute for the RCP2512W100RJS2 with the following considerations:

Electrical and mechanical compatibility is confirmed across all critical parameters. The RCP2512W100RGEB provides improved tolerance specification (±2% versus ±5%), which may benefit applications requiring tighter resistance accuracy without affecting interchangeability.

The RCP2512W100RGEB achieves ROHS3 compliance, whereas the RCP2512W100RJS2 is RoHS non-compliant. Selection between these parts should be based on regulatory and procurement requirements specific to the end application and target market.

Both parts maintain identical power rating, package dimensions, temperature performance, and moisture resistance characteristics, confirming direct substitution capability at the component level.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W100RGEB replace RCP2512W100RJS2 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 100 Ohms resistance, 4.6W power rating, 2512 package, ±150ppm/°C temperature coefficient, and -65°C to 155°C operating range. The tolerance difference (±2% versus ±5%) represents an improvement in accuracy and does not prevent substitution.

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

A: The RCP2512W100RGEB features ±2% tolerance and ROHS3 compliance, while the RCP2512W100RJS2 features ±5% tolerance and is RoHS non-compliant. All other electrical and mechanical specifications are identical.

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 assembly compatibility are maintained.

Q: Does tolerance difference affect circuit performance?

A: Tolerance affects resistance accuracy. The RCP2512W100RGEB's ±2% tolerance provides tighter accuracy compared to the RCP2512W100RJS2's ±5% tolerance. Selection depends on circuit requirements for resistance precision.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
