Substitute Part Grouping Explanation

Substitution eligibility for RC3216F515CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 5.1 MOhms (exact match required)
• Tolerance: ±1% (precision grade must match)
• Power rating: 0.25W / 1/4W (thermal capacity must match)
• Package: 1206 (3216 Metric) (physical footprint must match)
• Composition: Thick Film (construction method must match)
• Temperature coefficient: ±100ppm/°C (stability must match)
• Operating temperature range: -55°C to 155°C (functional range must match)
• RoHS compliance: ROHS3 Compliant (regulatory requirement must match)
• MSL rating: 1 (Unlimited) (moisture handling must match)

Substitute Classification:

Direct Equivalent: RC1206FR-075M1L (YAGEO) — Identical electrical specifications and moisture resistance features. Differs only in packaging format (Cut Tape & Digi-Reel vs. standard packaging) and minor dimensional tolerance (3.10mm vs. 3.20mm length).

Upgrade Equivalent: AC1206FR-075M1L (YAGEO) — Meets all electrical parameters with addition of Automotive AEC-Q200 qualification. Suitable for applications requiring automotive-grade reliability without compromising standard industrial performance.

Similar Equivalents: CRCW12065M10FKEA (Vishay Dale) and KTR18EZPF5104 (Rohm Semiconductor) — Both meet all core electrical and mechanical parameters with Automotive AEC-Q200 qualification. KTR18EZPF5104 includes High Voltage feature designation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): RC1206FR-075M1L from YAGEO is the primary direct equivalent. This part maintains all electrical parameters, moisture resistance, and regulatory compliance identical to the original RC3216F515CS. Selection is appropriate for applications where original Samsung sourcing is unavailable and no additional automotive qualification is required.

For Automotive or Enhanced Reliability Applications: AC1206FR-075M1L (YAGEO), CRCW12065M10FKEA (Vishay Dale), or KTR18EZPF5104 (Rohm Semiconductor) are suitable when designs require Automotive AEC-Q200 qualification. All three parts maintain core electrical specifications while adding automotive-grade reliability certification. KTR18EZPF5104 includes High Voltage feature designation for applications with elevated voltage stress requirements.

Inventory Availability Consideration: KTR18EZPF5104 maintains highest inventory level (24263 units), followed by AC1206FR-075M1L (10867 units) and RC1206FR-075M1L (10378 units). Selection based on supply chain requirements should reference current inventory status.

Compliance Status: All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) rating, ensuring regulatory equivalence and moisture handling compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-075M1L be used as a direct replacement for RC3216F515CS?

A: Yes. RC1206FR-075M1L meets all mandatory electrical and mechanical parameters: 5.1 MOhms ±1%, 0.25W power rating, 1206 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL Level 1 rating. The only differences are minor dimensional tolerances (3.10mm vs. 3.20mm length) and packaging format, which do not affect electrical performance or PCB assembly compatibility.

Q: What is the difference between RC1206FR-075M1L and AC1206FR-075M1L?

A: Both parts are manufactured by YAGEO and share identical electrical specifications (5.1 MOhms ±1%, 0.25W, 1206 package). The primary difference is that AC1206FR-075M1L includes Automotive AEC-Q200 qualification, making it suitable for automotive applications requiring enhanced reliability standards. RC1206FR-075M1L is specified for general industrial applications without automotive certification.

Q: Are CRCW12065M10FKEA and KTR18EZPF5104 interchangeable with RC3216F515CS?

A: Both parts are electrically and mechanically compatible with RC3216F515CS across all core parameters. Both include Automotive AEC-Q200 qualification. KTR18EZPF5104 includes additional High Voltage feature designation. Selection between these parts and the original should be based on application requirements for automotive qualification and voltage stress conditions.

Q: Does the absence of "Moisture Resistant" designation on CRCW12065M10FKEA and KTR18EZPF5104 affect compatibility?

A: Both CRCW12065M10FKEA and KTR18EZPF5104 maintain MSL Level 1 (Unlimited) rating, which indicates equivalent moisture handling capability to the original RC3216F515CS. The absence of explicit "Moisture Resistant" feature designation does not indicate reduced moisture protection; it reflects different manufacturer specification documentation practices.

Q: Can these substitute parts be used in high-temperature applications?

A: Yes. All substitute parts maintain the identical operating temperature range of -55°C to 155°C and temperature coefficient of ±100ppm/°C as the original RC3216F515CS. Selection among substitutes should be based on application-specific requirements for automotive qualification or high-voltage performance rather than temperature capability.

Q: What packaging formats are available for these substitute parts?

A: RC1206FR-075M1L is available in Cut Tape (CT) & Digi-Reel format. AC1206FR-075M1L, CRCW12065M10FKEA, and KTR18EZPF5104 are available in Tape & Reel (TR) format. Packaging selection should align with assembly process requirements and inventory management practices.
