RCS3216F3402CS Equivalent & Substitute Parts

Part Overview

The RCS3216F3402CS is a 34 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 currently Active in product status with 1128 pieces in stock inventory.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package size and form factor), and environmental performance characteristics. Substitutes maintain identical or functionally equivalent performance within the defined operating parameters.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence:

• Resistance value: 34 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Equivalence:

• Package type: 1206 (3216 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions compatible within package specification

Environmental & Compliance Equivalence:

• Composition: Thick Film (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

All four substitute parts listed meet these criteria and are therefore direct functional equivalents to the RCS3216F3402CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status):

CR1206-FX-3402ELF (Bourns Inc.) and RC1206FR-0734KL (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status, ensuring long-term availability and continued manufacturing support. CRCW120634K0FKEA (Vishay Dale) is also Active and includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability.

Secondary Selection (Legacy Status):

ERJ-8ENF3402V (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. This part remains functionally equivalent and is suitable for replacement or repair of existing assemblies but should not be selected for new product development.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) rating, matching the environmental and regulatory profile of the RCS3216F3402CS. Height variations among substitutes (0.024" to 0.030" seated height) fall within typical PCB assembly tolerances and do not affect electrical performance.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the RCS3216F3402CS?

A: Yes. All four substitute parts meet identical electrical specifications (34 kOhms ±1%, 0.25W), operate across the same temperature range (-55°C ~ 155°C), and are packaged in the 1206 (3216 Metric) form factor. They are direct functional equivalents for circuit applications.

Q: What is the difference between the substitute parts?

A: The primary differences are manufacturer identity and product status. CR1206-FX-3402ELF, CRCW120634K0FKEA, and RC1206FR-0734KL are all Active products with ongoing manufacturing support. ERJ-8ENF3402V is marked "Not For New Designs," indicating it is in legacy status. CRCW120634K0FKEA includes automotive AEC-Q200 qualification for applications requiring automotive-grade reliability.

Q: Does the height difference between parts affect PCB assembly?

A: Height variations range from 0.024" (0.60mm) to 0.030" (0.75mm) seated height. These differences fall within standard PCB assembly process tolerances and do not affect electrical performance or mechanical fit in standard 1206 footprints.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts, including the main part RCS3216F3402CS, are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute should I select for new product designs?

A: For new designs, select from CR1206-FX-3402ELF (Bourns), CRCW120634K0FKEA (Vishay Dale), or RC1206FR-0734KL (YAGEO), as these maintain Active product status. If automotive qualification is required, CRCW120634K0FKEA is the appropriate choice due to AEC-Q200 certification.

Q: Can I use ERJ-8ENF3402V in new designs?

A: ERJ-8ENF3402V is marked "Not For New Designs." It is suitable for replacement or repair of existing assemblies but should not be selected for new product development due to its legacy status.

Q: What packaging formats are available for these substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The main part RCS3216F3402CS is supplied in standard packaging format.
