RCP1206B10R0JS2 Equivalent & Substitute Parts

Part Overview

The RCP1206B10R0JS2 is a 10 Ohms ±5% 2.4W thick film chip resistor in 1206 (3216 Metric) package manufactured by Vishay Dale. This component is actively produced and widely used in applications requiring moisture-resistant surface mount resistors with moderate tolerance specifications. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained while offering improved specifications or availability advantages.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP1206B10R0JS2 is valid when the following core parameters remain constant or improve:

• Resistance value: 10 Ohms (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Power Rating: 2.4W (equal or higher acceptable)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±150ppm/°C (equal or better acceptable)
• Operating Temperature Range: -65°C ~ 155°C (equal or wider acceptable)
• Moisture Resistant feature: Required
• Moisture Sensitivity Level: 1 (Unlimited) (equal or better acceptable)

Tolerance may be tightened (improved) from ±5% to ±2% without affecting functional compatibility. Packaging format (Tape & Reel vs. Cut Tape) does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RCP1206W10R0GEB serves as a direct substitute for the RCP1206B10R0JS2 with the following considerations:

Tolerance improvement: The substitute part offers ±2% tolerance compared to ±5%, providing tighter resistance accuracy without affecting circuit compatibility.

Compliance advantage: The RCP1206W10R0GEB is ROHS3 compliant, whereas the main part is RoHS non-compliant. Selection of the substitute is appropriate for applications subject to RoHS regulatory requirements.

Electrical equivalence: All critical electrical parameters—resistance, power rating, temperature coefficient, and operating temperature range—are identical between both parts.

Mechanical compatibility: Both parts share identical package dimensions, footprint, and termination configuration, ensuring direct PCB layout compatibility.

Packaging format: The main part is supplied in Tape & Reel format; the substitute is supplied in Cut Tape format. This difference affects procurement and assembly logistics but not component performance.

Frequently Asked Questions (FAQ)

Q: Can RCP1206W10R0GEB replace RCP1206B10R0JS2 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. The substitute offers improved tolerance (±2% vs. ±5%) and RoHS3 compliance. PCB layout and circuit design require no modification.

Q: What is the significance of the tolerance difference between ±5% and ±2%?

A: Tolerance defines the acceptable resistance variation from the nominal 10 Ohm value. The ±2% tolerance of the substitute part provides a tighter resistance band (9.8–10.2 Ohms vs. 9.5–10.5 Ohms), resulting in higher accuracy. This is a specification improvement and does not create compatibility issues.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 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 does RoHS3 compliance mean for the substitute part?

A: RoHS3 compliance indicates the substitute part meets Restriction of Hazardous Substances regulations. The main part is RoHS non-compliant. Selection of the substitute is required for applications or markets with RoHS regulatory mandates.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect component performance?

A: No. Packaging format affects only procurement, storage, and assembly handling. Electrical and mechanical performance are identical regardless of packaging format.

Q: Are both parts actively manufactured?

A: Yes. Both the RCP1206B10R0JS2 and RCP1206W10R0GEB are listed as Active product status by Vishay Dale, ensuring continued availability and supply chain reliability.
