RC3216F2152CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F2152CS is a 21.5 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 with MSL 1 rating. The part is currently in active production status with 986 pieces available in inventory.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility across qualified component sources is needed. All substitute parts listed maintain electrical and mechanical compatibility within the specified parameters.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Parameters (Must Match Exactly):

• Resistance value: 21.5 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
• Composition: Thick Film

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. Two parts (CR1206-FX-2152ELF and RC1206FR-0721K5L) are classified as direct manufacturer equivalents. Two parts (CRCW120621K5FKEA and ERJ-8ENF2152V) are classified as similar parts with additional automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended for New Designs):

CR1206-FX-2152ELF (Bourns Inc.) and RC1206FR-0721K5L (YAGEO) are direct manufacturer equivalents with active product status. Both maintain identical electrical specifications and ROHS3 compliance. Selection between these two should be based on supply availability, packaging format preference (both available in Tape & Reel), and established supplier relationships. CR1206-FX-2152ELF has higher inventory availability (30,867 pieces) compared to RC1206FR-0721K5L (18,968 pieces).

Similar Parts with Enhanced Qualification (Conditional Use):

CRCW120621K5FKEA (Vishay Dale) carries AEC-Q200 automotive qualification in addition to standard specifications. This part is suitable for applications requiring automotive-grade reliability. Product status is active with the highest inventory level (55,499 pieces).

ERJ-8ENF2152V (Panasonic Electronic Components) also carries AEC-Q200 automotive qualification but is marked "Not For New Designs." This designation indicates the manufacturer is transitioning away from this part. While currently available in inventory (59,486 pieces), this part should be avoided for new design implementations.

Selection Criteria Summary:

• For standard applications: CR1206-FX-2152ELF or RC1206FR-0721K5L
• For automotive applications: CRCW120621K5FKEA
• Avoid for new designs: ERJ-8ENF2152V

Frequently Asked Questions (FAQ)

Q: Can I substitute RC3216F2152CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts maintain identical electrical parameters (21.5 kOhms ±1%, 0.25W, ±100ppm/°C) and mechanical compatibility (1206 package, 2 terminations). Direct PCB replacement is possible without circuit modification.

Q: What is the difference between "Direct Manufacturer Part Number" and "Similar Manufacturer Part Number" classifications?

A: Direct equivalents (CR1206-FX-2152ELF, RC1206FR-0721K5L) are functionally identical parts from different manufacturers with identical specifications. Similar parts (CRCW120621K5FKEA, ERJ-8ENF2152V) meet all core electrical and mechanical requirements but include additional qualifications (AEC-Q200 automotive rating) that may not be necessary for all applications.

Q: Does packaging format affect substitution compatibility?

A: Packaging format (Tape & Reel, Cut Tape, Digi-Reel) affects supply chain handling and assembly processes but does not affect electrical or mechanical compatibility. The component itself remains identical regardless of packaging format. Selection should align with your assembly equipment and procurement workflow.

Q: Why is ERJ-8ENF2152V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) is discontinuing this product line. While currently available, using this part in new designs creates future supply risk. For new applications, select from parts with active product status: CR1206-FX-2152ELF, RC1206FR-0721K5L, or CRCW120621K5FKEA.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts, including the main part RC3216F2152CS, are ROHS3 compliant with REACH Unaffected status. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.

Q: What is the practical difference in physical dimensions between these parts?

A: All parts conform to 1206 (3216 Metric) package specification. Minor variations exist in maximum seated height: RC3216F2152CS (0.66mm), CR1206-FX-2152ELF (0.75mm), RC1206FR-0721K5L (0.65mm), CRCW120621K5FKEA (0.60mm), ERJ-8ENF2152V (0.70mm). These variations are within standard PCB design tolerances and do not affect assembly compatibility.

Q: Which substitute part has the best inventory availability?

A: ERJ-8ENF2152V has the highest inventory (59,486 pieces), followed by CRCW120621K5FKEA (55,499 pieces). However, ERJ-8ENF2152V is marked "Not For New Designs." For active products, CRCW120621K5FKEA offers the best availability (55,499 pieces), followed by CR1206-FX-2152ELF (30,867 pieces).
