Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS3216F1274CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 1.27 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

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

Compliance Parameters:

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

The CRCW12061M27FKEA from Vishay Dale meets all electrical and mechanical equivalence criteria. This substitute maintains identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. Both parts utilize thick film composition and are housed in the 1206 package with equivalent termination configuration. Compliance certifications align across RoHS3 and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS3216F1274CS and CRCW12061M27FKEA are active products with full regulatory compliance. The RCS3216F1274CS features anti-sulfur and moisture-resistant construction specific to general industrial applications. The CRCW12061M27FKEA carries AEC-Q200 automotive qualification, indicating suitability for automotive-grade applications with enhanced reliability requirements.

Selection between these parts depends on application requirements. For general industrial use, the RCS3216F1274CS provides the specified performance. For automotive or mission-critical applications requiring automotive-grade qualification, the CRCW12061M27FKEA is the appropriate selection. Both parts satisfy identical electrical specifications and physical package requirements, ensuring direct functional interchangeability within their respective application domains.

The maximum seated height difference of 0.002" (0.06mm) between parts is negligible for standard PCB assembly and does not impact circuit performance or board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CRCW12061M27FKEA directly replace the RCS3216F1274CS in any application?

A: Both parts are electrically and mechanically equivalent across all critical parameters including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. Both are housed in the 1206 package with identical footprints. Direct substitution is supported from an electrical and mechanical standpoint. Application-specific requirements such as automotive qualification should be evaluated independently.

Q: What is the significance of the AEC-Q200 rating on the CRCW12061M27FKEA?

A: AEC-Q200 is an automotive industry qualification standard indicating the part meets enhanced reliability and quality requirements for automotive applications. This certification is not present on the RCS3216F1274CS. Selection of the AEC-Q200 qualified part is necessary only when automotive-grade specifications are mandated by application requirements.

Q: Are there any physical compatibility concerns between these two parts?

A: Both parts conform to the 1206 (3216 Metric) package standard with identical length and width dimensions of 0.126" x 0.063" (3.20mm x 1.60mm). The maximum seated height differs by 0.002" (0.06mm), which does not impact PCB assembly, soldering, or circuit performance. Physical compatibility is confirmed.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Both parts are ROHS3 compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Regulatory and environmental compliance requirements are equivalent across both parts.

Q: What is the difference in packaging between these parts?

A: The RCS3216F1274CS is supplied in standard packaging format. The CRCW12061M27FKEA is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume automated assembly operations. Packaging format selection depends on assembly process requirements and order quantities.

Q: Are the temperature coefficients identical?

A: Both parts specify a temperature coefficient of ±100ppm/°C and operate across the identical temperature range of -55°C to 155°C. Temperature stability characteristics are equivalent.
