Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F34R8CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 34.8 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these core requirements. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in packaging format (Tape & Reel) do not affect functional substitution. Product status and specific feature sets (such as automotive AEC-Q200 certification) are noted for application-specific selection but do not prevent substitution in non-restricted applications.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Applications: The CRCW120634R8FKEA (Vishay Dale) and RC1206FR-0734R8L (YAGEO) are both in active production status and represent primary substitution options. Both parts maintain full compliance with ROHS3 standards and MSL Level 1 ratings.

For Automotive Applications: The CRCW120634R8FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive circuit designs. The ERJ-8ENF34R8V (Panasonic) also carries AEC-Q200 certification but is marked as "Not For New Designs," limiting its use to legacy system support or existing inventory management.

For General Industrial Applications: All four parts are functionally equivalent for non-automotive applications. Selection may be based on availability, packaging preference (Tape & Reel format), or existing supply chain relationships.

Compliance Considerations: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. No additional compliance verification is required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can CRCW120634R8FKEA directly replace RCS3216F34R8CS in circuit design? A: Yes. Both parts share identical electrical specifications (34.8 Ohms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C to 155°C), and 1206 package dimensions. Physical height variation (0.024" vs 0.026") is within 1206 package tolerance and does not affect PCB layout or soldering.

Q: Why is ERJ-8ENF34R8V marked "Not For New Designs"? A: This designation indicates the part is in mature/legacy status. While electrically and mechanically equivalent, Panasonic recommends using alternative sources for new product development. Existing inventory may be used for legacy system support or maintenance applications.

Q: Are there packaging format differences between substitutes? A: The RCS3216F34R8CS is supplied in standard packaging, while CRCW120634R8FKEA, ERJ-8ENF34R8V, and RC1206FR-0734R8L are supplied in Tape & Reel (TR) format. Both formats contain identical components; packaging format affects handling and automated assembly processes but not electrical performance.

Q: What is the significance of the slight dimension variation in RC1206FR-0734R8L? A: The RC1206FR-0734R8L has a length of 0.122" (3.10mm) compared to 0.126" (3.20mm) for other parts. This 0.004" difference is within 1206 package specification tolerances and does not affect PCB footprint compatibility or soldering performance.

Q: Are all substitutes MSL Level 1 rated? A: Yes. All four parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Can these parts be used interchangeably in automotive applications? A: CRCW120634R8FKEA and ERJ-8ENF34R8V carry AEC-Q200 certification for automotive use. RCS3216F34R8CS and RC1206FR-0734R8L do not carry this certification. For automotive applications, use AEC-Q200 qualified parts unless the application does not require automotive qualification.
