RCS3216F751CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F751CS is a 750 Ohm ±1% 0.25W (1/4W) thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This component features anti-sulfur and moisture-resistant construction, operating across the temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are necessary to address supply chain flexibility, alternative sourcing options, and application-specific requirements such as automotive qualification or enhanced power ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F751CS is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 750 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

All substitute parts listed meet these core electrical and mechanical specifications. Secondary considerations include manufacturer certifications (such as AEC-Q200 for automotive applications), RoHS compliance status, and packaging format (Tape & Reel versus Cut Tape). Parts with higher power ratings (0.75W) or non-compliant RoHS status are identified separately and require explicit design review before substitution.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (ROHS3 Compliant, 0.25W, Active Status):

The following parts are direct functional equivalents with identical electrical specifications and current active production status:

• AC1206FR-07750RL (YAGEO): AEC-Q200 qualified, ROHS3 compliant, Tape & Reel packaging
• CR1206-FX-7500ELF (Bourns Inc.): ROHS3 compliant, Tape & Reel packaging
• CRCW1206750RFKEA (Vishay Dale): AEC-Q200 qualified, ROHS3 compliant, Tape & Reel packaging
• RC1206FR-07750RL (YAGEO): ROHS3 compliant, Cut Tape & Digi-Reel packaging, highest inventory availability
• RMCF1206FT750R (Stackpole Electronics Inc): AEC-Q200 qualified, ROHS3 compliant, Tape & Reel packaging

Conditional Substitutes:

• CRCW1206750RFKEAHP (Vishay Dale): Higher power rating (0.75W vs. 0.25W). Suitable only for applications where increased power dissipation capacity is required or beneficial. Identical package and temperature specifications.

• ERJ-8ENF7500V (Panasonic Electronic Components): AEC-Q200 qualified, ROHS3 compliant. Product status is "Not For New Designs." Acceptable for legacy system maintenance or existing design continuity only.

• CRCW1206750RFKTA (Vishay Dale): RoHS non-compliant and REACH affected. Substitution requires explicit compliance review and is not recommended for new designs or regulated applications.

Packaging Considerations:

Tape & Reel (TR) packaging is standard for high-volume automated assembly. Cut Tape (CT) & Digi-Reel packaging (RC1206FR-07750RL) is suitable for lower-volume or mixed-component orders.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206750RFKEAHP (0.75W) be used as a direct replacement for RCS3216F751CS (0.25W)?

A: CRCW1206750RFKEAHP meets all electrical and mechanical specifications and operates within the same temperature range. The higher power rating (0.75W) does not prevent substitution; however, circuit design must accommodate the different thermal characteristics. Substitution is permissible from an electrical standpoint.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly in high-volume production. Cut Tape (CT) & Digi-Reel packaging is suitable for lower-volume orders or mixed-component procurement. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Is ERJ-8ENF7500V suitable for new product designs?

A: ERJ-8ENF7500V carries a "Not For New Designs" product status. This part is acceptable for maintenance, repair, or continuation of existing designs but should not be selected for new development. For new designs, select from parts with "Active" status.

Q: Why is CRCW1206750RFKTA listed if it is RoHS non-compliant?

A: CRCW1206750RFKTA is included for reference and legacy system support. RoHS non-compliance and REACH-affected status restrict its use to applications where regulatory compliance is not required. New designs and regulated applications must use ROHS3-compliant alternatives.

Q: Are all substitute parts AEC-Q200 qualified?

A: No. AEC-Q200 qualification is present in AC1206FR-07750RL, CRCW1206750RFKEA, CRCW1206750RFKEAHP, CRCW1206750RFKTA, ERJ-8ENF7500V, and RMCF1206FT750R. The main part (RCS3216F751CS), CR1206-FX-7500ELF, and RC1206FR-07750RL do not carry AEC-Q200 certification. Automotive applications requiring AEC-Q200 qualification must select from the qualified subset.

Q: What is the significance of ±100ppm/°C temperature coefficient?

A: Temperature coefficient of ±100ppm/°C defines the maximum resistance change per degree Celsius across the operating temperature range. All listed parts share this specification, ensuring equivalent thermal stability and predictable performance across -55°C to 155°C.

Q: Can I substitute based on package dimensions alone?

A: No. While all parts use the 1206 (3216 Metric) package, dimensional variations exist (height ranges from 0.60mm to 0.75mm). Substitution must be based on complete electrical specifications (resistance, tolerance, power rating, temperature coefficient) and compliance status, not package dimensions alone.
