Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216J305CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3 MOhms
• Package / Case: 1206 (3216 Metric)
• Power rating: 0.25W (1/4W)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant
• Number of terminations: 2

Tolerance Consideration: Substitute parts are grouped into two categories based on tolerance specification. The main part RCS3216J305CS operates at ±5% tolerance. Substitute parts with ±1% tolerance are electrically compatible and represent improved precision alternatives. Parts with ±5% tolerance provide direct functional equivalence.

All identified substitute parts maintain identical electrical performance characteristics, thermal behavior, and environmental compliance ratings as the main part.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalence (±5% Tolerance Match): RC1206JR-073ML from YAGEO provides direct functional equivalence to RCS3216J305CS with identical ±5% tolerance specification. Both parts maintain the same electrical performance envelope and are suitable for applications where tolerance matching is a design requirement.

Enhanced Precision Alternatives (±1% Tolerance): AC1206FR-073ML, CRCW12063M00FKEA, KTR18EZPF3004, and RC1206FR-073ML all offer ±1% tolerance, representing improved precision over the main part. These substitutes are electrically compatible and provide tighter resistance value control. Selection among these options depends on additional design criteria not specified in the core electrical parameters.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and MSL Level 1 rating identical to the main part. AC1206FR-073ML and CRCW12063M00FKEA carry AEC-Q200 automotive qualification. KTR18EZPF3004 includes both AEC-Q200 automotive qualification and high-voltage capability designation. These certifications do not affect substitution eligibility for non-automotive applications but provide additional qualification pathways for regulated environments.

Product Availability: All identified substitute parts maintain Active product status with confirmed inventory availability, ensuring long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can RC1206JR-073ML directly replace RCS3216J305CS without circuit modification?

A: Yes. RC1206JR-073ML is a direct functional equivalent with matching ±5% tolerance, identical 3 MOhms resistance, 0.25W power rating, 1206 package, and all thermal and environmental specifications. No circuit modification is required.

Q: What is the difference between ±5% and ±1% tolerance substitutes?

A: The main part RCS3216J305CS operates at ±5% tolerance, meaning the actual resistance value can vary between 2.85 MOhms and 3.15 MOhms. Substitute parts with ±1% tolerance (AC1206FR-073ML, CRCW12063M00FKEA, KTR18EZPF3004, RC1206FR-073ML) provide tighter control, with actual values between 2.97 MOhms and 3.03 MOhms. Both tolerance classes are electrically compatible; selection depends on circuit precision requirements.

Q: Are the physical dimensions identical across all substitute parts?

A: All parts use the 1206 (3216 Metric) package with 2 terminations. Length dimensions vary slightly between 0.122" (3.10mm) and 0.126" (3.20mm), and height dimensions range from 0.024" (0.60mm) to 0.026" (0.66mm). These variations fall within standard 1206 package tolerances and do not affect PCB layout compatibility or reflow soldering processes.

Q: Which substitute part should be selected for automotive applications?

A: AC1206FR-073ML, CRCW12063M00FKEA, and KTR18EZPF3004 all carry AEC-Q200 automotive qualification. The main part RCS3216J305CS does not include this certification. For automotive applications requiring AEC-Q200 compliance, select from these three qualified alternatives.

Q: Is moisture sensitivity different between the main part and substitutes?

A: No. All parts, including RCS3216J305CS and all five substitute options, maintain MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q: Can substitute parts be mixed in the same production batch?

A: Yes. All substitute parts maintain identical electrical performance, thermal characteristics, and environmental compliance. Mixed sourcing is permissible from a functional standpoint. However, design documentation and supply chain procedures should reflect the specific part numbers used in each production lot for traceability and future service requirements.

Q: What is the significance of "High Voltage" designation on KTR18EZPF3004?

A: KTR18EZPF3004 includes high-voltage capability in its feature set. This designation indicates enhanced performance characteristics for high-voltage applications but does not restrict use in standard voltage applications. The part remains fully compatible with RCS3216J305CS for all specified operating conditions.
