RC3216F2103CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F2103CS is a 210 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film, moisture-resistant resistor operates across -55°C to 155°C and is ROHS3 compliant. The part is currently in active production status with 738 pieces available in inventory.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits cross-manufacturer sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Criteria:

• Resistance value: 210 kOhms
• 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
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within standard tolerances and packaging format (Tape & Reel) do not affect functional substitutability. Product status and specific feature enhancements (such as automotive AEC-Q200 qualification) are noted for design consideration but do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

CR1206-FX-2103ELF (Bourns Inc.) and CRCW1206210KFKEA (Vishay Dale) are recommended as primary alternatives. Both parts maintain active production status and carry ROHS3 compliance. CRCW1206210KFKEA includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-07210KL (YAGEO) is an active substitute with lower inventory levels.

Secondary Substitute (Legacy Status):

ERJ-8ENF2103V (Panasonic Electronic Components) is classified as "Not For New Designs" and carries automotive AEC-Q200 qualification. This part is suitable for replacement or repair of existing assemblies but should not be selected for new product development.

Selection Basis:

All substitutes are electrically and mechanically equivalent to the RC3216F2103CS. Selection among active alternatives depends on supply availability, packaging requirements (all available in Tape & Reel format), and application-specific needs such as automotive qualification. The ERJ-8ENF2103V should be avoided in new designs due to its legacy status.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-2103ELF replace RC3216F2103CS directly on the PCB?

A: Yes. Both parts are 1206 (3216 Metric) package with identical electrical specifications (210 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C). Physical dimensions are within standard tolerances. No PCB layout modifications are required.

Q: What is the difference between the moisture-resistant and AEC-Q200 variants?

A: The RC3216F2103CS and CR1206-FX-2103ELF are specified as moisture-resistant thick film resistors. The CRCW1206210KFKEA and ERJ-8ENF2103V include automotive AEC-Q200 qualification, indicating compliance with automotive reliability standards. Both feature sets are compatible with the same 1206 package and electrical parameters. AEC-Q200 qualification is an enhancement, not a requirement for general-purpose applications.

Q: Is ERJ-8ENF2103V suitable for new product designs?

A: No. ERJ-8ENF2103V is marked "Not For New Designs." This designation indicates the manufacturer is phasing out this part number. Use this part only for repair or replacement of existing assemblies. For new designs, select from active alternatives: CR1206-FX-2103ELF, RC1206FR-07210KL, or CRCW1206210KFKEA.

Q: Do all substitutes have the same moisture sensitivity level?

A: Yes. All listed substitutes carry Moisture Sensitivity Level 1 (Unlimited), matching the RC3216F2103CS. This classification indicates no special moisture handling precautions are required during storage or assembly.

Q: Are there dimensional differences between substitutes?

A: Minor dimensional variations exist within standard tolerances. RC3216F2103CS and CRCW1206210KFKEA measure 0.126" L × 0.063" W. RC1206FR-07210KL measures 0.122" L × 0.063" W. Height variations range from 0.024" to 0.030" (0.60mm to 0.75mm). These differences do not affect PCB footprint compatibility or functional performance in standard 1206 land patterns.

Q: Which substitute has the highest inventory availability?

A: CR1206-FX-2103ELF (Bourns Inc.) has the highest inventory with 45,003 pieces available, followed by CRCW1206210KFKEA (Vishay Dale) with 34,563 pieces. RC1206FR-07210KL (YAGEO) has 1,953 pieces available.
