Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F754CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 750 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.25W / 1/4W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Equivalence Requirements:

• Package type: 1206 (3216 Metric) (exact match)
• Composition: Thick Film (exact match)
• Number of terminations: 2 (exact match)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

All identified substitute parts meet these core criteria. Additional features such as automotive AEC-Q200 certification or anti-sulfur construction represent enhanced capabilities that do not preclude substitution but indicate suitability for specialized applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Recommended for New Designs):

RC3216F754CS (Samsung Electro-Mechanics) and RC1206FR-07750KL (YAGEO) are direct functional equivalents with Active product status. Both maintain identical electrical and mechanical specifications to the RCS3216F754CS. RC3216F754CS represents the closest match within the same manufacturer family, while RC1206FR-07750KL provides an alternative from an established supplier with high inventory availability.

Automotive-Qualified Alternatives:

AC1206FR-07750KL (YAGEO) and KTR18EZPF7503 (Rohm Semiconductor) incorporate Automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability. Both maintain Active product status. KTR18EZPF7503 additionally features high-voltage capability. These parts are interchangeable with the RCS3216F754CS in standard applications and provide enhanced qualification for automotive environments.

Bourns Alternative:

CR1206-FX-7503ELF (Bourns Inc.) offers functional equivalence with Active status and substantial inventory availability. This part is suitable for direct substitution in applications where Bourns component qualification is preferred or required.

Legacy Component (Not Recommended for New Designs):

ERJ-8ENF7503V (Panasonic Electronic Components) carries "Not For New Designs" status despite meeting all electrical and mechanical specifications. This designation indicates the manufacturer is phasing out this product line. Substitution is functionally valid for maintenance or repair of existing assemblies but should not be selected for new product development.

Frequently Asked Questions (FAQ)

Q: Can RC3216F754CS replace RCS3216F754CS directly?

A: Yes. RC3216F754CS is a direct functional equivalent manufactured by Samsung Electro-Mechanics. Both parts share identical resistance (750 kΩ), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The primary difference is packaging format (Cut Tape & Digi-Reel® versus standard packaging). Electrical and mechanical interchangeability is complete.

Q: What is the difference between parts with and without AEC-Q200 certification?

A: AEC-Q200 certification indicates the part meets automotive industry reliability and quality standards established by the Automotive Electronics Council. Parts such as AC1206FR-07750KL and KTR18EZPF7503 carry this certification. For non-automotive applications, AEC-Q200 certification is not required but represents additional qualification. All AEC-Q200 certified parts listed are functionally equivalent to the RCS3216F754CS in standard applications.

Q: Why is ERJ-8ENF7503V marked "Not For New Designs"?

A: This designation indicates Panasonic Electronic Components is discontinuing this product line. While ERJ-8ENF7503V meets all electrical and mechanical specifications for the RCS3216F754CS, it should not be selected for new product development. Use this part only for maintenance, repair, or replacement of existing assemblies containing this component.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within the 1206 package specification. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), and maximum seated height ranges from 0.026" to 0.030" (0.65mm to 0.75mm). These variations remain within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility. All parts are mechanically interchangeable in standard 1206 footprints.

Q: What does "Anti-Sulfur" construction mean in the RCS3216F754CS?

A: Anti-sulfur construction provides enhanced resistance to sulfur-containing environmental contaminants that can degrade resistor performance. The RCS3216F754CS includes this feature; most substitute parts feature standard moisture resistance. For applications in high-sulfur environments, the RCS3216F754CS or equivalent anti-sulfur variants are preferred, though standard moisture-resistant parts remain functionally compatible.

Q: Can I use KTR18EZPF7503 in place of RCS3216F754CS?

A: Yes. KTR18EZPF7503 is a functional equivalent with Active product status. It matches all critical electrical parameters (750 kΩ, ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and mechanical specifications (1206 package). The additional high-voltage feature does not preclude substitution in standard applications. This part is suitable for direct replacement.

Q: What inventory considerations should guide part selection?

A: Inventory availability varies significantly among substitutes. KTR18EZPF7503 (Rohm Semiconductor) shows the highest inventory at 289,785 pieces, followed by CR1206-FX-7503ELF (Bourns Inc.) at 17,231 pieces and AC1206FR-07750KL (YAGEO) at 10,700 pieces. For applications requiring immediate availability or long-term supply assurance, parts with higher inventory levels provide supply chain advantages while maintaining full functional equivalence.
