Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F39R2CS is determined by strict matching of the following critical parameters:

Electrical Specifications: Resistance value (39.2 Ohms), tolerance (±1%), and power rating (0.25W) must be identical across all substitute parts.

Package Compatibility: All substitute parts must use the 1206 (3216 Metric) surface mount package with two terminations to ensure PCB footprint compatibility.

Environmental Specifications: Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C to 155°C) must match to maintain circuit performance across specified conditions.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and MSL 1 rating to satisfy regulatory and manufacturing process requirements.

Composition: Thick film construction is maintained across all substitutes to preserve electrical and thermal characteristics.

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the RCS3216F39R2CS in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Production): RMCF1206FT39R2 (Stackpole Electronics Inc) is recommended as the primary substitute. This part maintains active product status, carries AEC-Q200 automotive qualification, and has the highest inventory availability (129,842 pcs). It is suitable for both standard and automotive-grade applications.

Secondary Selection (Active Production): CRCW120639R2FKEA (Vishay Dale) is an active alternative with AEC-Q200 automotive qualification and substantial inventory (20,746 pcs). This part is appropriate for applications requiring automotive-grade reliability.

Tertiary Selection (Active Production): RC1206FR-0739R2L (YAGEO) is an active product with the highest inventory level (68,978 pcs) and moisture-resistant features matching the original part. This option is suitable for general-purpose applications without automotive requirements.

Legacy Consideration: ERJ-8ENF39R2V (Panasonic Electronic Components) carries "Not For New Designs" status and should be used only for replacement or repair of existing assemblies. While inventory is available (54,200 pcs), this part is not recommended for new circuit designs.

All substitute parts maintain identical electrical performance, package compatibility, and compliance certifications with the RCS3216F39R2CS.

Frequently Asked Questions (FAQ)

Q: Can CRCW120639R2FKEA replace RCS3216F39R2CS directly on the PCB?

A: Yes. Both parts use the 1206 (3216 Metric) package with identical footprint dimensions (0.126" L x 0.063" W). Electrical specifications (39.2 Ohms ±1%, 0.25W) and environmental ratings (-55°C to 155°C) are identical. Direct PCB substitution is supported.

Q: What is the difference between the Samsung RCS3216F39R2CS and Stackpole RMCF1206FT39R2?

A: Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, and package specifications. The primary difference is manufacturer and AEC-Q200 automotive qualification on the Stackpole part. The Samsung part features anti-sulfur construction, while the Stackpole part carries automotive-grade certification.

Q: Why is ERJ-8ENF39R2V marked "Not For New Designs"?

A: This designation indicates the Panasonic part is in mature/legacy status. While the part remains available and functionally equivalent, Panasonic recommends using alternative sources for new circuit designs. This part is appropriate only for replacement or repair of existing assemblies.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (CRCW120639R2FKEA, ERJ-8ENF39R2V, RC1206FR-0739R2L, RMCF1206FT39R2) maintain ROHS3 compliance matching the original RCS3216F39R2CS specification.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All substitute parts carry this rating, meaning they can be stored and handled without special moisture control procedures, matching the original part's handling requirements.

Q: Can I use CRCW120639R2FKEA in automotive applications?

A: Yes. CRCW120639R2FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive-grade circuit applications. The original RCS3216F39R2CS does not carry this certification.

Q: What are the physical dimension differences between substitutes?

A: Length varies slightly: RCS3216F39R2CS and CRCW120639R2FKEA are 0.126" (3.20mm), while RC1206FR-0739R2L is 0.122" (3.10mm). Height ranges from 0.024" to 0.028" across all parts. These minor variations remain within 1206 package tolerance and do not affect PCB compatibility.
