Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP1206B1K00JS2 is determined by the following critical parameters that must remain constant or improve:

• 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 capability
• Moisture Sensitivity Level: Must be MSL 1 or better

The RCP1206W1K00GEB qualifies as a direct substitute because it maintains all critical parameters while offering improved tolerance specification (±2% versus ±5%) and enhanced RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The RCP1206W1K00GEB serves as a direct functional substitute for the RCP1206B1K00JS2 in applications where component specifications are interchangeable. Both parts maintain identical electrical performance characteristics, physical dimensions, and thermal operating ranges. The primary distinction is the tolerance specification improvement (±2% versus ±5%) and RoHS3 compliance status of the substitute part. Selection between these parts should be based on application tolerance requirements and regulatory compliance mandates. Both parts are active in production with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RCP1206W1K00GEB replace RCP1206B1K00JS2 in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package dimensions, and operating temperature range. The substitute offers improved tolerance specification and enhanced compliance certification.

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

A: The main part RCP1206B1K00JS2 has ±5% tolerance, while the substitute RCP1206W1K00GEB has ±2% tolerance. The tighter tolerance of the substitute part provides improved accuracy for precision circuit applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 1206 (3216 Metric) with identical dimensions of 0.122" L x 0.060" W (3.10mm x 1.52mm) and maximum seated height of 0.025" (0.64mm). They are mechanically interchangeable on PCBs.

Q: What is the difference in RoHS compliance?

A: The main part RCP1206B1K00JS2 is RoHS non-compliant, while the substitute RCP1206W1K00GEB is ROHS3 compliant. Applications subject to RoHS regulations should use the compliant substitute part.

Q: Do both parts have the same moisture resistance rating?

A: Yes. Both parts feature moisture-resistant thick film composition with MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations for storage or handling.

Q: Are the packaging formats different?

A: Yes. The main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format. Both formats are standard for SMD component distribution and do not affect electrical or mechanical compatibility.
