Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCP1206B1K00JS3 is determined by the following critical parameters:

• Resistance Value: Must be 1 kOhms
• Package / Case: Must be 1206 (3216 Metric)
• Power Rating: Must be 2.4W or greater
• Composition: Must be Thick Film
• Temperature Coefficient: Must be ±150ppm/°C or better
• Operating Temperature Range: Must cover -65°C ~ 155°C
• Features: Must include Moisture Resistant
• Number of Terminations: Must be 2
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The RCP1206W1K00GEB qualifies as a direct substitute based on these parameters. While tolerance is improved (±2% versus ±5%), all other electrical and mechanical specifications remain equivalent or superior, ensuring functional interchangeability in applications where the main part is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the RCP1206B1K00JS3 and RCP1206W1K00GEB are active production components from Vishay Dale with identical electrical and mechanical specifications. The primary distinction is compliance certification: the RCP1206W1K00GEB achieves ROHS3 compliance, while the main part is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. The RCP1206W1K00GEB additionally offers improved tolerance (±2% versus ±5%), which may benefit applications requiring tighter resistance accuracy. Both components are suitable for direct substitution in 1206 package footprints with equivalent thermal and environmental performance.

Frequently Asked Questions (FAQ)

Q: Can RCP1206W1K00GEB replace RCP1206B1K00JS3 in existing designs?

A: Yes. Both components share identical package dimensions (1206 / 3216 Metric), resistance value (1 kOhms), power rating (2.4W), temperature range (-65°C ~ 155°C), and moisture resistance characteristics. PCB footprints and thermal performance are equivalent.

Q: What is the difference in tolerance between these parts?

A: The main part RCP1206B1K00JS3 has ±5% tolerance, while the substitute RCP1206W1K00GEB has ±2% tolerance. The tighter tolerance of the substitute part does not affect interchangeability but may provide improved accuracy in precision applications.

Q: Are there packaging differences between these parts?

A: Yes. The RCP1206B1K00JS3 is supplied in Tape & Reel (TR) packaging, while RCP1206W1K00GEB is supplied in Cut Tape (CT) packaging. Both are suitable for automated assembly; packaging selection depends on production volume and handling requirements.

Q: Does RoHS compliance affect substitution eligibility?

A: RoHS compliance is a regulatory and supply chain consideration, not an electrical or mechanical one. The RCP1206W1K00GEB's ROHS3 compliance makes it preferable for applications subject to RoHS regulations. The main part remains functionally equivalent for applications without such requirements.

Q: Are the thermal characteristics identical?

A: Yes. Both parts have identical temperature coefficients (±150ppm/°C) and operating temperature ranges (-65°C ~ 155°C), ensuring equivalent performance across thermal extremes.
