Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F3161CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (3.16 kOhms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Compatibility: Package type (1206/3216 Metric), footprint dimensions, and termination count (2) must match or be compatible with PCB design requirements.

Environmental & Compliance: Operating temperature range (-55°C ~ 155°C), moisture sensitivity level (MSL 1), RoHS3 compliance, and REACH status must be maintained.

Composition & Features: Thick film construction and moisture-resistant characteristics must be preserved.

Substitute parts are classified as either Direct Equivalents (identical specifications across all parameters) or Similar Alternatives (meeting all critical electrical and mechanical requirements with additional certifications such as AEC-Q200 automotive qualification).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Preferred for Drop-In Replacement):

CR1206-FX-3161ELF (Bourns Inc.) and RC1206FR-073K16L (YAGEO) are direct functional equivalents meeting all electrical and mechanical specifications. Both maintain active product status with high inventory availability. CR1206-FX-3161ELF offers Tape & Reel packaging suitable for automated assembly, while RC1206FR-073K16L provides Cut Tape and Digi-Reel® options for flexible procurement.

Similar Alternatives (Additional Certifications):

CRCW12063K16FKEA (Vishay Dale) and ERJ-8ENF3161V (Panasonic Electronic Components) meet all core specifications with additional AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability. CRCW12063K16FKEA maintains active production status. ERJ-8ENF3161V carries "Not For New Designs" status, limiting its use to legacy system support or existing inventory management.

Selection Criteria:

For new designs, select from CR1206-FX-3161ELF, RC1206FR-073K16L, or CRCW12063K16FKEA based on packaging requirements and supply chain preferences. For automotive applications, CRCW12063K16FKEA is the recommended choice. Avoid ERJ-8ENF3161V for new product development.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-3161ELF replace RC3216F3161CS directly on the PCB?

A: Yes. Both parts share identical electrical specifications (3.16 kOhms ±1%, 0.25W, ±100ppm/°C) and mechanical compatibility (1206 package, 2 terminations). Physical dimensions are equivalent within manufacturing tolerances. Substitution is electrically and mechanically valid.

Q: What is the difference between "Direct Equivalent" and "Similar Alternative" classifications?

A: Direct equivalents (CR1206-FX-3161ELF, RC1206FR-073K16L) match all specified parameters without additional features. Similar alternatives (CRCW12063K16FKEA, ERJ-8ENF3161V) include AEC-Q200 automotive certification, making them suitable for automotive applications but not required for general industrial use.

Q: Why is ERJ-8ENF3161V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development for this part number. While existing inventory remains available and functionally equivalent, Panasonic recommends alternative parts for new product designs. Use ERJ-8ENF3161V only for legacy system maintenance or existing production runs.

Q: Are there packaging format differences that affect compatibility?

A: Yes. RC3216F3161CS is supplied in bulk format. CR1206-FX-3161ELF and ERJ-8ENF3161V use Tape & Reel (TR) packaging for automated assembly. RC1206FR-073K16L offers Cut Tape (CT) and Digi-Reel® options. Packaging format affects procurement and assembly processes but does not impact electrical or mechanical performance on the PCB.

Q: Do all substitute parts maintain RoHS3 and REACH compliance?

A: Yes. All listed substitute parts (CR1206-FX-3161ELF, RC1206FR-073K16L, CRCW12063K16FKEA, ERJ-8ENF3161V) are ROHS3 compliant and REACH unaffected, matching the compliance profile of RC3216F3161CS.

Q: Which substitute offers the highest inventory availability?

A: ERJ-8ENF3161V (Panasonic) has the largest inventory at 94,121 units. However, due to its "Not For New Designs" status, CR1206-FX-3161ELF (20,055 units) or RC1206FR-073K16L (17,926 units) are preferred for active projects.

Q: Can CRCW12063K16FKEA be used in non-automotive applications?

A: Yes. CRCW12063K16FKEA meets all general specifications and exceeds requirements through AEC-Q200 certification. It is suitable for any application requiring 3.16 kOhms ±1% 0.25W 1206 resistors, whether automotive or industrial.
