RCS3216J515CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216J515CS is a 5.1 MOhm ±5% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with anti-sulfur and moisture-resistant properties. The part is ROHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the 1206 package form factor, resistance value, power rating, and operating temperature range. Substitution becomes necessary due to inventory availability, supply chain optimization, or specific application requirements such as automotive qualification or enhanced tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RCS3216J515CS is based on the following mandatory parameters:

Core Electrical Parameters:

• Resistance value: 5.1 MOhms (exact match required)
• Power rating: 0.25W minimum (equal or higher acceptable)
• Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)
• Temperature coefficient: ±100ppm/°C or better

Mechanical Parameters:

• Package: 1206 (3216 Metric) form factor (exact match required)
• Composition: Thick Film (exact match required)
• Terminations: 2-terminal configuration (exact match required)

Compliance Parameters:

• RoHS3 compliance (mandatory)
• MSL Level 1 or better (mandatory)

Substitute parts are grouped into two categories based on tolerance specification:

Category A - Tolerance Match (±5%): RC1206JR-075M1L maintains identical ±5% tolerance specification as the main part.

Category B - Enhanced Tolerance (±1%): AC1206FR-075M1L, CRCW12065M10FKEA, KTR18EZPF5104, and RC1206FR-075M1L offer tighter ±1% tolerance, providing superior accuracy while maintaining all other electrical and mechanical compatibility parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Tolerance Match): RC1206JR-075M1L from YAGEO maintains the ±5% tolerance specification identical to RCS3216J515CS. This part is suitable for applications where the original tolerance specification is a design requirement. All electrical, mechanical, and compliance parameters are equivalent.

Enhanced Tolerance Substitutes (±1%): AC1206FR-075M1L, CRCW12065M10FKEA, KTR18EZPF5104, and RC1206FR-075M1L provide ±1% tolerance specification, representing a tighter accuracy class than the original part. These substitutes are electrically and mechanically compatible and maintain full ROHS3 compliance and MSL Level 1 rating.

Automotive-Qualified Alternatives: AC1206FR-075M1L (YAGEO), CRCW12065M10FKEA (Vishay Dale), and KTR18EZPF5104 (Rohm Semiconductor) carry AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade component certification in addition to standard industrial compliance.

Packaging Considerations:

• AC1206FR-075M1L: Tape & Reel (TR) packaging
• CRCW12065M10FKEA: Tape & Reel (TR) packaging
• KTR18EZPF5104: Tape & Reel (TR) packaging
• RC1206FR-075M1L: Cut Tape (CT) & Digi-Reel® packaging
• RC1206JR-075M1L: Tape & Reel (TR) packaging

Selection between substitute parts should be based on application tolerance requirements, automotive qualification necessity, and packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-075M1L replace RCS3216J515CS in all applications? A: AC1206FR-075M1L is electrically and mechanically compatible with RCS3216J515CS. The ±1% tolerance of AC1206FR-075M1L is tighter than the ±5% specification of RCS3216J515CS, making it suitable for applications where the original tolerance is acceptable or where improved accuracy is beneficial. Both parts share identical power rating, package, operating temperature range, and compliance certifications.

Q: What is the difference between the substitute parts? A: All substitute parts maintain the 5.1 MOhm resistance, 0.25W power rating, 1206 package, and -55 to 155°C operating temperature range. Primary differences are: (1) Tolerance specification (±1% for most substitutes versus ±5% for RC1206JR-075M1L), (2) Automotive AEC-Q200 qualification (present in AC1206FR-075M1L, CRCW12065M10FKEA, and KTR18EZPF5104), and (3) Packaging format (Tape & Reel versus Cut Tape).

Q: Is RC1206JR-075M1L a direct equivalent to RCS3216J515CS? A: RC1206JR-075M1L is a direct equivalent in terms of tolerance specification (both ±5%), resistance value, power rating, package, and operating temperature range. All electrical and mechanical parameters are compatible. The primary difference is manufacturer (YAGEO versus Samsung Electro-Mechanics).

Q: Can I use automotive-qualified parts in non-automotive applications? A: Yes. Automotive-qualified parts such as AC1206FR-075M1L, CRCW12065M10FKEA, and KTR18EZPF5104 meet or exceed industrial-grade specifications and are suitable for non-automotive applications. AEC-Q200 qualification represents additional quality and reliability testing beyond standard industrial requirements.

Q: What packaging format should I select? A: Packaging selection depends on assembly process requirements. Tape & Reel (TR) format is standard for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® format (RC1206FR-075M1L) is suitable for lower-volume or manual assembly processes. All formats are compatible with the 1206 package footprint.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of RCS3216J515CS.
