Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3216F1784CS are identified based on strict equivalence of the following parameters:

• Resistance Value: 1.78 MOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Package Designation: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Termination Count: 2 (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (minimum requirement)

The CRCW12061M78FKEA from Vishay Dale meets all electrical and mechanical equivalence criteria. Additional qualification (AEC-Q200 automotive rating) does not disqualify it as a substitute; it represents an enhanced specification variant suitable for broader application scope.

Parameter Comparison

Engineering Selection Recommendations

RC3216F1784CS (Samsung Electro-Mechanics): Select this part when Samsung sourcing is specified or preferred. Active production status and ROHS3 compliance support standard commercial and industrial applications. Moisture-resistant construction provides baseline environmental protection.

CRCW12061M78FKEA (Vishay Dale): Select this part when AEC-Q200 automotive qualification is required or when Vishay Dale is the preferred supplier. All electrical and mechanical parameters are equivalent to the Samsung part. The automotive qualification extends suitability to automotive and high-reliability applications without compromising compatibility with standard industrial designs. Tape & Reel packaging supports automated assembly processes.

Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for commercial distribution.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061M78FKEA replace RC3216F1784CS in any application?

A: Yes. Both parts share identical electrical specifications (1.78 MOhms ±1%, 0.25W), identical package dimensions (1206 / 3216 Metric), and identical operating temperature range (-55°C ~ 155°C). The CRCW12061M78FKEA includes AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications.

Q: What is the difference in physical height between these parts?

A: RC3216F1784CS has a maximum seated height of 0.026" (0.66mm). CRCW12061M78FKEA has a maximum seated height of 0.024" (0.60mm). Both heights are within standard 1206 package tolerances and compatible with typical PCB assembly processes.

Q: Are both parts suitable for moisture-sensitive environments?

A: Yes. Both parts have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. The RC3216F1784CS includes explicit moisture-resistant construction; the CRCW12061M78FKEA meets the same MSL classification.

Q: What packaging formats are available?

A: RC3216F1784CS is supplied in standard packaging (specific format not detailed in provided data). CRCW12061M78FKEA is supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RC3216F1784CS and CRCW12061M78FKEA are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component distribution.
