Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F5493CS is determined by the following critical parameters:

Electrical Specifications: Resistance value (549 kOhms), tolerance (±1%), and power rating (0.25W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package type (1206 / 3216 Metric) and number of terminations (2) are mandatory for PCB footprint compatibility. Physical dimensions must accommodate the 1206 form factor.

Environmental & Compliance Requirements: Moisture Sensitivity Level 1 (Unlimited) is standard across all candidates. RoHS3 compliance and REACH status are documented for regulatory alignment.

Product Status: Active production status is preferred for long-term availability, though parts marked "Not For New Designs" may serve as interim solutions.

All identified substitute parts meet the core electrical and mechanical criteria, with variations noted in specific features (automotive AEC-Q200 certification, anti-sulfur vs. moisture-resistant properties) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Production, Full Compliance):

CRCW1206549KFKEA (Vishay Dale) and RC1206FR-07549KL (YAGEO) are recommended as primary equivalents. Both parts maintain active product status, achieve ROHS3 compliance, and demonstrate full electrical and mechanical compatibility with the RCS3216F5493CS. CRCW1206549KFKEA includes automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability. RC1206FR-07549KL provides moisture-resistant thick film construction aligned with the original part's environmental specifications.

Secondary Substitute (Compliance Consideration):

CRCW1206549KFKTA (Vishay Dale) offers identical electrical and mechanical specifications with automotive AEC-Q200 certification. However, this variant is marked as RoHS non-compliant and REACH Affected, restricting its use in applications subject to RoHS3 or REACH regulatory requirements.

Legacy Alternative (Not For New Designs):

ERJ-8ENF5493V (Panasonic Electronic Components) maintains full electrical compatibility and ROHS3 compliance but carries a "Not For New Designs" product status. This part is suitable only for replacement or repair of existing assemblies where design continuity is required.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206549KFKEA directly replace RCS3216F5493CS in existing designs?

A: Yes. Both parts share identical resistance (549 kOhms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Physical dimensions and termination count are compatible. CRCW1206549KFKEA includes automotive AEC-Q200 certification, which does not restrict its use in non-automotive applications.

Q: What is the difference between CRCW1206549KFKEA and CRCW1206549KFKTA?

A: Both Vishay Dale parts are electrically and mechanically identical. The primary difference is regulatory compliance: CRCW1206549KFKEA is ROHS3 Compliant and REACH Unaffected, while CRCW1206549KFKTA is RoHS non-compliant and REACH Affected. Selection depends on regulatory requirements of the end application.

Q: Why is ERJ-8ENF5493V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development for this part number. While the part remains electrically and mechanically compatible, it is reserved for maintenance and repair of existing assemblies. New designs should utilize active production alternatives such as CRCW1206549KFKEA or RC1206FR-07549KL.

Q: Are there height differences between substitute parts?

A: Yes. Seated height varies: RCS3216F5493CS (0.66mm), CRCW1206549KFKEA (0.60mm), CRCW1206549KFKTA (0.60mm), ERJ-8ENF5493V (0.70mm), and RC1206FR-07549KL (0.65mm). All heights remain within typical 1206 package tolerances. Verify PCB clearance requirements for applications with height-sensitive constraints.

Q: What packaging formats are available?

A: RCS3216F5493CS is supplied in bulk packaging. All substitute parts (CRCW1206549KFKEA, CRCW1206549KFKTA, ERJ-8ENF5493V, RC1206FR-07549KL) are available in Tape & Reel (TR) format, standard for automated assembly processes.

Q: Which substitute offers the best inventory availability?

A: ERJ-8ENF5493V (Panasonic) has the highest inventory at 48,329 pieces. CRCW1206549KFKEA (Vishay Dale) provides 18,550 pieces. RC1206FR-07549KL (YAGEO) has 10,149 pieces. CRCW1206549KFKTA (Vishay Dale) has 6,025 pieces. Inventory levels should be confirmed with suppliers for current availability.
