Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F18R7CS are qualified based on the following criteria:

Electrical Parameters: Resistance value of 18.7 Ohms, tolerance of ±1%, and power rating of 0.25W (1/4W) must match exactly.

Mechanical Parameters: Package designation of 1206 (3216 Metric) with two terminations ensures physical and electrical compatibility on printed circuit boards.

Environmental Parameters: Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C must be maintained.

Compliance Parameters: ROHS3 compliance and MSL 1 rating are required for equivalent substitution.

Composition: Thick film construction is the specified technology for all qualified substitutes.

The three identified substitute parts meet all these criteria and are therefore direct functional equivalents suitable for replacement in applications where the RCS3216F18R7CS is specified.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: CRCW120618R7FKEA (Vishay Dale) or RC1206FR-0718R7L (YAGEO) are recommended for new designs. Both parts maintain Active product status, ensuring long-term availability and supply chain stability. CRCW120618R7FKEA includes automotive AEC-Q200 qualification, providing additional reliability assurance for demanding applications. RC1206FR-0718R7L offers equivalent performance with moisture-resistant construction matching the original specification.

Alternative Selection: ERJ-8ENF18R7V (Panasonic) is functionally equivalent with AEC-Q200 automotive qualification. However, this part carries a "Not For New Designs" status, limiting its suitability for new product development. Existing designs currently using this component may continue with this part for continuity.

Compliance Consideration: All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with modern manufacturing and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW120618R7FKEA directly replace RCS3216F18R7CS?

A: Yes. Both parts share identical electrical specifications (18.7 Ohms ±1%, 0.25W), package designation (1206), temperature characteristics (±100ppm/°C, -55°C to 155°C), and compliance ratings (ROHS3, MSL 1). Physical dimensions are equivalent, enabling direct board-level substitution.

Q: What is the difference between the substitute parts?

A: CRCW120618R7FKEA and RC1206FR-0718R7L are both Active products suitable for new designs. CRCW120618R7FKEA includes AEC-Q200 automotive qualification. ERJ-8ENF18R7V carries identical electrical and thermal specifications but is marked "Not For New Designs," making it suitable only for legacy design support.

Q: Are there dimensional differences between these parts?

A: Dimensional variations exist within acceptable tolerances. RCS3216F18R7CS and CRCW120618R7FKEA have maximum seated heights of 0.66mm and 0.60mm respectively. ERJ-8ENF18R7V measures 0.70mm maximum, and RC1206FR-0718R7L measures 0.65mm maximum. All dimensions remain within 1206 package specifications and do not affect circuit board assembly compatibility.

Q: Which part should be selected for automotive applications?

A: CRCW120618R7FKEA is qualified to AEC-Q200 automotive standards, making it the preferred choice for automotive circuit designs. ERJ-8ENF18R7V also carries AEC-Q200 qualification but is restricted from new designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RCS3216F18R7CS, CRCW120618R7FKEA, ERJ-8ENF18R7V, and RC1206FR-0718R7L all maintain ROHS3 compliance and MSL 1 rating, meeting current environmental and manufacturing standards.
