RCS3216F1052CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F1052CS is a 10.5 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when they maintain identical electrical specifications (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical compatibility (package type, footprint dimensions, termination count) while meeting equivalent compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1052CS is determined by strict equivalence across the following parameters:

Electrical Parameters (Must Match Exactly):

• Resistance: 10.5 kOhms
• Tolerance: ±1%
• Power Rating: 0.25W (1/4W)
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package Type: 1206 (3216 Metric)
• Number of Terminations: 2
• Footprint Compatibility: 0.126" L x 0.063" W (3.20mm x 1.60mm nominal)

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All four substitute parts listed meet these criteria. Variations in seated height (0.024" to 0.030") remain within acceptable PCB assembly tolerances for 1206 packages and do not affect substitutability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-1052ELF (Bourns Inc.) and CRCW120610K5FKEA (Vishay Dale) are recommended as primary substitutes. Both maintain active product status with full manufacturing support. CRCW120610K5FKEA carries AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-0710K5L (YAGEO) is also active and provides equivalent performance with established supply availability.

Secondary Substitute (Legacy Status):

ERJ-8ENF1052V (Panasonic Electronic Components) is marked "Not For New Designs" and carries AEC-Q200 qualification. This part remains electrically and mechanically equivalent but should be used only in existing production lines or legacy system maintenance where design continuity is required.

Compliance Alignment:

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory equivalence with the primary RCS3216F1052CS part.

Frequently Asked Questions (FAQ)

Q: Can I substitute RCS3216F1052CS with any of these parts in new designs?

A: Yes, CR1206-FX-1052ELF, CRCW120610K5FKEA, and RC1206FR-0710K5L are all active products suitable for new designs. ERJ-8ENF1052V is marked "Not For New Designs" and should be avoided in new applications.

Q: What determines if a part is a valid substitute?

A: Valid substitutes must match the resistance value (10.5 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), package type (1206), and compliance standards (ROHS3, MSL 1).

Q: Are there differences in physical dimensions between these parts?

A: Seated height varies between 0.024" and 0.030" across the substitute parts. These variations fall within standard PCB assembly tolerances for 1206 packages and do not affect substitutability or board-level performance.

Q: Do any of these substitutes have automotive qualification?

A: Yes, CRCW120610K5FKEA (Vishay Dale) and ERJ-8ENF1052V (Panasonic) both carry AEC-Q200 automotive qualification. The Samsung RCS3216F1052CS, Bourns CR1206-FX-1052ELF, and YAGEO RC1206FR-0710K5L do not list automotive qualification.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: The RCS3216F1052CS specifies both anti-sulfur and moisture-resistant properties. Substitute parts specify moisture-resistant or automotive AEC-Q200 features. All parts maintain MSL 1 (Unlimited) rating, indicating equivalent moisture handling capability.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. All parts share identical electrical specifications, 1206 package footprint, and two-terminal configuration. Mechanical height variations are within PCB assembly process tolerances.

Q: Which substitute offers the best supply availability?

A: Based on inventory data, ERJ-8ENF1052V (Panasonic) shows 49,689 pieces in stock, followed by CRCW120610K5FKEA (Vishay Dale) with 22,985 pieces, and RC1206FR-0710K5L (YAGEO) with 31,499 pieces.
