RCP1206B75R0JS3 Equivalent & Substitute Parts

Part Overview

The RCP1206B75R0JS3 is a 75 Ohm ±5% 2.4W chip resistor in 1206 (3216 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 improved tolerance specifications or enhanced compliance certifications are necessary for system requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP1206B75R0JS3 is determined by strict equivalence in the following parameters:

• Resistance value: 75 Ohms (exact match required)
• Power rating: 2.4W (exact match required)
• Package / Case: 1206 (3216 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 Sensitivity Level: 1 (Unlimited) (exact match required)

Tolerance may vary within acceptable design margins. RoHS compliance status and inventory availability are secondary considerations that do not affect electrical or mechanical substitutability.

Parameter Comparison

Engineering Selection Recommendations

The RCP1206W75R0GEB serves as a direct substitute for the RCP1206B75R0JS3 with the following considerations:

Electrical performance is equivalent across all critical parameters: resistance value, power rating, temperature coefficient, and operating temperature range remain unchanged. The RCP1206W75R0GEB provides improved tolerance specification (±2% versus ±5%), which enhances precision in applications requiring tighter resistance values.

The RCP1206W75R0GEB achieves ROHS3 compliance, whereas the RCP1206B75R0JS3 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements or customer specifications mandating compliant components.

Both parts share identical mechanical compatibility: 1206 package footprint, dimensions, and termination configuration ensure direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can RCP1206W75R0GEB replace RCP1206B75R0JS3 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. The RCP1206W75R0GEB features improved tolerance (±2% versus ±5%) and ROHS3 compliance. No PCB layout modifications are required.

Q: What is the tolerance difference between these parts?

A: The RCP1206B75R0JS3 has ±5% tolerance, while the RCP1206W75R0GEB has ±2% tolerance. The tighter tolerance of the substitute part provides greater resistance value accuracy without affecting circuit functionality.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1206 (3216 Metric) package with identical dimensions: 0.122" L x 0.060" W (3.10mm x 1.52mm) and maximum seated height of 0.025" (0.64mm). They are footprint-compatible.

Q: What is the significance of RoHS compliance?

A: The RCP1206W75R0GEB is ROHS3 compliant, while the RCP1206B75R0JS3 is not. RoHS compliance is required for applications subject to European Union regulations or customer specifications mandating lead-free, halogen-free components.

Q: Do both parts have the same operating temperature range?

A: Yes. Both parts operate across -65°C to 155°C with identical temperature coefficient of ±150ppm/°C.

Q: Are there any packaging differences?

A: Both parts are supplied in Tape & Reel (TR) packaging. No packaging differences affect component handling or assembly processes.
