RCS3216F3400CS Equivalent & Substitute Parts

Part Overview

The RCS3216F3400CS is a 340 Ohm ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with anti-sulfur and moisture-resistant construction. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and package compatibility. Substitute components maintain identical resistance value, tolerance, power rating, and package form factor while potentially offering alternative feature sets or manufacturer certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F3400CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 340 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)

Compliance Parameters (Must Match):

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

Substitute parts may differ in manufacturer, packaging format (Tape & Reel vs. bulk), seated height tolerance, and additional certifications (such as AEC-Q200 automotive qualification). These differences do not affect functional interchangeability in standard applications.

Engineering Selection Recommendations

Primary Substitute: CRCW1206340RFKEA (Vishay Dale)

The CRCW1206340RFKEA is the recommended substitute for new designs and production applications. This part maintains Active product status and carries AEC-Q200 automotive qualification. All electrical and mechanical parameters align with the RCS3216F3400CS. The seated height of 0.024" (0.60mm) is within acceptable tolerance for standard PCB assembly processes. Packaging is supplied in Tape & Reel format suitable for automated assembly.

Secondary Substitute: ERJ-8ENF3400V (Panasonic)

The ERJ-8ENF3400V is functionally equivalent but carries a "Not For New Designs" product status designation. This part is suitable for replacement and repair applications where existing inventory exists. The seated height of 0.028" (0.70mm) remains within acceptable mechanical tolerances. AEC-Q200 automotive certification is provided. This part should not be selected for new product development.

Primary Application: RCS3216F3400CS

For new designs requiring the original Samsung specification without automotive certification requirements, the RCS3216F3400CS remains the appropriate selection with Active product status.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206340RFKEA be used as a direct replacement for RCS3216F3400CS?

A: Yes. Both parts share identical electrical specifications (340 Ohms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C ~ 155°C operating range), and mechanical package (1206 / 3216 Metric). Compliance ratings (ROHS3, MSL 1) are equivalent. The CRCW1206340RFKEA includes AEC-Q200 automotive certification, which does not restrict use in non-automotive applications.

Q: What is the difference in seated height between these parts?

A: The RCS3216F3400CS has a maximum seated height of 0.026" (0.66mm), the CRCW1206340RFKEA is 0.024" (0.60mm), and the ERJ-8ENF3400V is 0.028" (0.70mm). These variations fall within standard PCB assembly tolerances and do not affect interchangeability for typical applications. Height differences may be relevant only in space-constrained designs with strict clearance requirements.

Q: Why is ERJ-8ENF3400V marked "Not For New Designs"?

A: The "Not For New Designs" designation indicates that Panasonic has discontinued active development and promotion of this part number. While the part remains functionally equivalent and available in inventory, it should not be selected for new product development. Use CRCW1206340RFKEA or RCS3216F3400CS for new designs.

Q: Are all three parts ROHS3 compliant?

A: Yes. RCS3216F3400CS, CRCW1206340RFKEA, and ERJ-8ENF3400V are all ROHS3 compliant with REACH Unaffected status. All parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: What packaging formats are available?

A: RCS3216F3400CS is supplied in standard packaging format. CRCW1206340RFKEA and ERJ-8ENF3400V are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. Tape & Reel packaging is compatible with pick-and-place equipment used in modern PCB manufacturing.

Q: Can these parts be used in automotive applications?

A: CRCW1206340RFKEA and ERJ-8ENF3400V carry AEC-Q200 automotive qualification and are suitable for automotive applications. RCS3216F3400CS does not specify automotive certification but meets all electrical and environmental specifications required for automotive use. Application suitability depends on specific automotive qualification requirements of the end product.
