Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F2433CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 243 kOhms
• 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 compatible with 1206 footprint

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these core requirements. Variations in packaging format (Tape & Reel vs. bulk), specific feature sets (Automotive AEC-Q200 certification), and minor dimensional tolerances do not affect functional interchangeability in standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The CRCW1206243KFKEA (Vishay Dale) and RC1206FR-07243KL (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status, ensuring long-term availability and supply chain stability. The CRCW1206243KFKEA includes Automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability. The RC1206FR-07243KL provides standard industrial-grade performance with moisture-resistant properties matching the original part.

Secondary Selection (Legacy Applications): The ERJ-8ENF2433V (Panasonic) is classified as "Not For New Designs" and should be used only in legacy system maintenance or replacement scenarios where existing inventory must be maintained. This part meets all electrical and mechanical specifications but is not recommended for new circuit designs.

Compliance Considerations: All substitute parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. MSL rating of 1 (Unlimited) across all parts ensures compatibility with standard PCB assembly processes without moisture bake-out requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206243KFKEA be used as a direct replacement for RCS3216F2433CS?

A: Yes. Both parts share identical electrical specifications (243 kOhms ±1%, 0.25W), operate across -55°C to 155°C, and use the 1206 package. The CRCW1206243KFKEA includes Automotive AEC-Q200 certification, providing enhanced reliability for demanding applications. Seated height differs by 0.002" (0.06mm), which is within standard PCB assembly tolerances.

Q: What is the difference between the Samsung RCS3216F2433CS and YAGEO RC1206FR-07243KL?

A: Both parts are functionally equivalent with matching resistance, tolerance, power rating, and operating temperature range. The primary differences are manufacturer and packaging format. The Samsung part features anti-sulfur properties, while the YAGEO part emphasizes moisture resistance. Both are Active products suitable for new designs.

Q: Why is the Panasonic ERJ-8ENF2433V marked "Not For New Designs"?

A: The ERJ-8ENF2433V meets all electrical and mechanical requirements for direct substitution but carries a "Not For New Designs" status, indicating the manufacturer is phasing out this product line. This part should be reserved for legacy system maintenance only. For new circuit designs, select CRCW1206243KFKEA or RC1206FR-07243KL.

Q: Are there packaging format differences between these substitute parts?

A: The RCS3216F2433CS is available in bulk packaging, while CRCW1206243KFKEA, ERJ-8ENF2433V, and RC1206FR-07243KL are supplied in Tape & Reel (TR) format. Both packaging formats contain identical components; the difference affects handling, storage, and automated assembly compatibility. Tape & Reel format is standard for high-volume SMD assembly operations.

Q: Do all substitute parts meet the same environmental compliance standards?

A: Yes. All substitute parts are ROHS3 Compliant, REACH Unaffected, and carry MSL rating 1 (Unlimited). These certifications ensure compatibility with current environmental regulations and standard PCB assembly processes without special moisture handling requirements.

Q: What is the significance of the ±100ppm/°C temperature coefficient across all parts?

A: The temperature coefficient specifies resistance drift over the operating temperature range. A ±100ppm/°C coefficient means the resistance value changes by approximately 0.01% per degree Celsius. This specification is identical across all parts, ensuring predictable performance in temperature-sensitive circuit applications.

Q: Can these parts be used interchangeably in automotive applications?

A: The CRCW1206243KFKEA carries Automotive AEC-Q200 certification and is explicitly qualified for automotive use. The RCS3216F2433CS, ERJ-8ENF2433V, and RC1206FR-07243KL do not carry automotive certifications. For automotive applications, CRCW1206243KFKEA is the appropriate selection.
