Substitute Part Grouping Explanation

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

Electrical Equivalence Requirements:

Resistance value: 16 kOhms (exact match)
Tolerance: ±1% (exact match)
Power rating: 0.25W / 1/4W (exact match)
Temperature coefficient: ±100ppm/°C (exact match)
Operating temperature range: -55°C to 155°C (exact match)

Mechanical Equivalence Requirements:

Package type: 1206 (3216 Metric) (exact match)
Number of terminations: 2 (exact match)
Composition: Thick Film (exact match)

Compliance Requirements:

RoHS3 compliance (required)
MSL 1 rating (required)
REACH unaffected status (required)

All identified substitute parts meet these criteria. Parts are classified as Direct Manufacturer equivalents when packaging and physical dimensions are identical, or Similar when minor dimensional variations exist within acceptable mechanical tolerances for 1206 package footprints.

Engineering Selection Recommendations

Direct Manufacturer Equivalents (Preferred for New Designs):

CR1206-FX-1602ELF (Bourns Inc.) and RC1206FR-0716KL (YAGEO) are direct functional equivalents with active product status. Both maintain identical electrical specifications and 1206 package compliance. CR1206-FX-1602ELF offers higher inventory availability (24,870 pieces). RC1206FR-0716KL provides the lowest seated height (0.65mm) among active alternatives.

Similar Equivalents (Automotive-Qualified):

CRCW120616K0FKEA (Vishay Dale) is an AEC-Q200 automotive-qualified alternative with active status. This part is suitable for applications requiring automotive-grade reliability certification. Seated height is 0.60mm, the lowest among all listed options.

Legacy Status (Not Recommended for New Designs):

ERJ-8ENF1602V (Panasonic Electronic Components) carries "Not For New Designs" status despite meeting all electrical and mechanical specifications. This part is available in inventory (44,994 pieces) but should be used only for legacy system maintenance or repair applications where original part sourcing is unavailable.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-1602ELF directly replace RC3216F163CS in existing designs?

A: Yes. Both parts share identical electrical specifications (16 kΩ ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C), package type (1206), and compliance ratings (ROHS3, MSL 1). The 0.09mm height difference (0.75mm vs. 0.66mm) is within standard 1206 package tolerances and does not affect PCB assembly or circuit performance.

Q: What is the difference between Direct Manufacturer and Similar equivalents?

A: Direct Manufacturer equivalents (CR1206-FX-1602ELF, RC1206FR-0716KL) are functionally identical with active production status. Similar equivalents (CRCW120616K0FKEA, ERJ-8ENF1602V) meet all electrical and mechanical requirements but may include additional certifications (AEC-Q200) or legacy status designations. All are mechanically compatible with 1206 footprints.

Q: Why is ERJ-8ENF1602V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development for this part number. While the component remains functionally equivalent and available in inventory, it should not be specified for new product designs. Use active-status alternatives (CR1206-FX-1602ELF, RC1206FR-0716KL, CRCW120616K0FKEA) for new applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL 1 (unlimited moisture sensitivity level) rating, matching the original RC3216F163CS specifications.

Q: Does package height variation affect PCB assembly?

A: No. All parts use the 1206 (3216 Metric) package with height variations between 0.60mm and 0.75mm. These differences fall within standard 1206 package tolerances and do not impact reflow soldering, component placement, or circuit board clearances.

Q: Which substitute offers the best inventory availability?

A: CR1206-FX-1602ELF (Bourns Inc.) provides the highest inventory level at 24,870 pieces, followed by RC1206FR-0716KL (YAGEO) at 78,165 pieces. Both are suitable for high-volume production requirements.
