RC3216F1052CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F1052CS is a 10.5 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant. The part is currently Active in product status with 930 pieces in stock inventory.

Substitute parts are identified when electrical specifications (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical parameters (package type, dimensions, termination count) are identical or functionally equivalent. Alternative sources provide equivalent performance for applications requiring component availability, supply chain diversification, or specific packaging formats.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence Requirements:

• Resistance value: 10.5 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)
• Number of terminations: 2 (exact match)
• Composition: Thick Film (exact match)
• Moisture resistance: Required feature (exact match)

Compliance Requirements:

• RoHS3 compliance (all substitutes meet this requirement)
• MSL 1 rating (all substitutes meet this requirement)

All four substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the RC3216F1052CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-1052ELF (Bourns Inc.) and RC1206FR-0710K5L (YAGEO) are recommended as primary alternatives. Both maintain Active product status, ensuring long-term availability and continued manufacturer support. These parts are supplied in Tape & Reel format, suitable for automated assembly processes.

CRCW120610K5FKEA (Vishay Dale) is qualified for automotive applications under AEC-Q200 standard. This part is appropriate for designs requiring automotive-grade reliability and traceability, despite identical electrical and mechanical specifications to non-automotive variants.

Secondary Substitute (Legacy Status):

ERJ-8ENF1052V (Panasonic Electronic Components) carries "Not For New Designs" product status. While electrically and mechanically equivalent, this part should be reserved for replacement or maintenance applications in existing designs. New designs should prioritize Active-status alternatives.

Compliance Verification:

All substitute parts maintain ROHS3 compliance and MSL 1 rating, confirming suitability for standard manufacturing and storage conditions without special moisture control requirements.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-1052ELF replace RC3216F1052CS in existing designs?

A: Yes. Both parts are electrically identical (10.5 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and mechanically compatible (1206 package, 2 terminations, thick film composition). The primary difference is packaging format: CR1206-FX-1052ELF is supplied in Tape & Reel while RC3216F1052CS is supplied in bulk. PCB footprint and soldering requirements are identical.

Q: What is the difference between CRCW120610K5FKEA and the other substitutes?

A: CRCW120610K5FKEA is qualified to AEC-Q200 automotive standard, providing enhanced reliability documentation and traceability for automotive applications. Electrically and mechanically, it is identical to all other substitutes. Use this part when automotive qualification is required; otherwise, any Active-status substitute is functionally equivalent.

Q: Why is ERJ-8ENF1052V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) is transitioning this product line and recommends alternative sources for new development. The part remains electrically and mechanically equivalent and is suitable for replacement in existing designs or legacy applications. For new designs, select CR1206-FX-1052ELF, RC1206FR-0710K5L, or CRCW120610K5FKEA.

Q: Are there dimensional differences between substitutes?

A: Minor dimensional variations exist within tolerance. RC3216F1052CS height is 0.026" (0.66mm); CR1206-FX-1052ELF is 0.030" (0.75mm); RC1206FR-0710K5L is 0.026" (0.65mm); CRCW120610K5FKEA is 0.024" (0.60mm); ERJ-8ENF1052V is 0.028" (0.70mm). Length varies slightly: RC3216F1052CS and CRCW120610K5FKEA are 0.126" (3.20mm); RC1206FR-0710K5L is 0.122" (3.10mm). These variations are within 1206 package specification and do not affect PCB layout or assembly compatibility.

Q: Which substitute offers the best inventory availability?

A: ERJ-8ENF1052V has the highest inventory (49,689 pieces), followed by RC1206FR-0710K5L (31,499 pieces) and CRCW120610K5FKEA (22,985 pieces). For new designs, prioritize CR1206-FX-1052ELF (25,956 pieces) or RC1206FR-0710K5L, both with Active status and substantial stock levels.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes, all substitutes are supplied in Tape & Reel format (except RC3216F1052CS in bulk) and are compatible with standard pick-and-place equipment. Verify tape specifications with your assembly partner if switching suppliers mid-production.
