Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F5493CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (549 kOhms), tolerance (±1%), and power rating (0.25W) must be identical. 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 and height specifications must accommodate existing circuit board layouts.

Environmental & Compliance Requirements: Moisture Sensitivity Level 1 (Unlimited) is required. RoHS3 compliance and REACH status are evaluated based on application requirements and regulatory jurisdiction.

Product Status Consideration: Active status parts are preferred for new designs. Parts with "Not For New Designs" status are identified for legacy system support only.

Substitute parts are grouped into two categories: Direct equivalents (matching all parameters including packaging format) and similar parts (matching electrical and mechanical specifications with variations in features or compliance ratings).

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliant Applications: RC1206FR-07549KL (YAGEO), CRCW1206549KFKEA (Vishay Dale), and ERJ-8ENF5493V (Panasonic) are suitable substitutes. All three maintain ROHS3 compliance status matching the original RC3216F5493CS specification.

For Automotive Applications: CRCW1206549KFKEA and CRCW1206549KFKTA (both Vishay Dale) and ERJ-8ENF5493V (Panasonic) include AEC-Q200 automotive qualification. These parts are appropriate for automotive circuit designs requiring enhanced reliability standards.

For New Design Implementations: RC1206FR-07549KL (YAGEO), CRCW1206549KFKEA (Vishay Dale), and RC3216F5493CS (Samsung) all carry Active product status. ERJ-8ENF5493V is classified as "Not For New Designs" and should be reserved for legacy system maintenance or replacement applications only.

For REACH Compliance: RC3216F5493CS, RC1206FR-07549KL, and ERJ-8ENF5493V maintain REACH Unaffected status. CRCW1206549KFKTA is REACH Affected and requires regulatory evaluation for specific jurisdictions.

For High-Volume Production: RC1206FR-07549KL (YAGEO) with 10,149 pieces in stock and ERJ-8ENF5493V (Panasonic) with 48,329 pieces in stock offer substantial inventory availability. CRCW1206549KFKEA (Vishay Dale) with 18,550 pieces provides mid-range availability.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07549KL replace RC3216F5493CS directly?

A: Yes. RC1206FR-07549KL meets all electrical specifications (549 kOhms ±1%, 0.25W), operates across the same temperature range (-55°C ~ 155°C), maintains identical tolerance and temperature coefficient (±100ppm/°C), and uses the same 1206 package. Both are ROHS3 compliant with MSL 1 rating. The primary difference is packaging format (Tape & Reel versus bulk) and manufacturer (YAGEO versus Samsung Electro-Mechanics).

Q: What is the difference between CRCW1206549KFKEA and CRCW1206549KFKTA?

A: Both parts are manufactured by Vishay Dale with identical electrical specifications and AEC-Q200 automotive qualification. The key difference is RoHS compliance: CRCW1206549KFKEA is ROHS3 compliant, while CRCW1206549KFKTA is RoHS non-compliant. CRCW1206549KFKEA is REACH Unaffected; CRCW1206549KFKTA is REACH Affected. For applications requiring RoHS3 compliance, CRCW1206549KFKEA is the appropriate selection.

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

A: ERJ-8ENF5493V carries a "Not For New Designs" product status designation from Panasonic Electronic Components. This classification indicates the part is available for existing system support and legacy applications but should not be selected for new circuit designs. For new implementations, select RC1206FR-07549KL, CRCW1206549KFKEA, or maintain RC3216F5493CS.

Q: Are all substitute parts compatible with existing PCB layouts?

A: All substitute parts use the 1206 (3216 Metric) package with 2 terminations, ensuring PCB footprint compatibility. Physical dimensions vary slightly: RC3216F5493CS and CRCW parts measure 0.126" L × 0.063" W (3.20mm × 1.60mm), while RC1206FR-07549KL measures 0.122" L × 0.063" W (3.10mm × 1.60mm). Height specifications range from 0.024" to 0.028" (0.60mm to 0.70mm). These dimensional variations remain within standard 1206 package tolerances and do not affect PCB assembly compatibility.

Q: Which substitute part offers the best inventory availability?

A: ERJ-8ENF5493V (Panasonic) provides the highest inventory with 48,329 pieces in stock. CRCW1206549KFKEA (Vishay Dale) offers 18,550 pieces, and RC1206FR-07549KL (YAGEO) provides 10,149 pieces. However, product status and compliance requirements should take precedence over inventory considerations in part selection.

Q: Can I use CRCW1206549KFKTA in a RoHS-regulated application?

A: No. CRCW1206549KFKTA is RoHS non-compliant and REACH Affected. For applications subject to RoHS3 requirements or REACH regulations, select CRCW1206549KFKEA (ROHS3 compliant, REACH Unaffected) or RC1206FR-07549KL (ROHS3 compliant, REACH Unaffected) instead.
