Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F2612CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 26.1 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

All substitute parts listed meet these mandatory parameters. Variations in physical dimensions (length, width, height) and packaging format (Tape & Reel vs. standard packaging) do not affect electrical substitutability. Product status and specific feature sets (anti-sulfur, moisture resistant, automotive AEC-Q200) are noted for application-specific selection but do not preclude substitution at the electrical level.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-2612ELF (Bourns Inc.) and RC1206FR-0726K1L (YAGEO) are recommended as primary substitutes. Both parts maintain active product status, ensuring long-term availability and continued manufacturer support. CR1206-FX-2612ELF offers high inventory availability (60,891 pcs) with moisture-resistant thick film construction. RC1206FR-0726K1L provides comparable specifications with slightly reduced physical height (0.65mm vs. 0.66mm), suitable for space-constrained applications.

Automotive-Qualified Alternative:

CRCW120626K1FKEA (Vishay Dale) is qualified to AEC-Q200 automotive standards and carries active product status. This part is appropriate for automotive and high-reliability applications requiring formal automotive qualification. Physical height is 0.024" (0.60mm), the lowest among all substitutes, beneficial for compact PCB designs.

Legacy Consideration:

ERJ-8ENF2612V (Panasonic Electronic Components) carries "Not For New Designs" status. While electrically equivalent and currently in stock (46,543 pcs), this part should be used only for legacy system maintenance or repair applications where design continuity is required. New designs should not incorporate this part number.

Frequently Asked Questions (FAQ)

Q: Can I directly replace RCS3216F2612CS with CR1206-FX-2612ELF on my PCB?

A: Yes. Both parts are 1206 (3216 Metric) package with identical electrical specifications (26.1 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C). Physical dimensions are compatible. The primary difference is packaging format (standard vs. Tape & Reel) and slight height variation (0.66mm vs. 0.75mm), which does not affect PCB placement or soldering.

Q: What is the difference between the Samsung RCS3216F2612CS and the Vishay CRCW120626K1FKEA?

A: Electrically, both parts are identical in resistance, tolerance, power rating, and temperature characteristics. The key difference is that CRCW120626K1FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive applications. The Samsung part features anti-sulfur properties in addition to moisture resistance. CRCW120626K1FKEA has a lower seated height (0.60mm vs. 0.66mm).

Q: Why is ERJ-8ENF2612V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and support for this product line. While the part remains electrically equivalent and is currently available, manufacturers recommend using alternative parts for new designs to ensure long-term supply chain stability and continued technical support. Use ERJ-8ENF2612V only for maintenance of existing systems.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (CR1206-FX-2612ELF, CRCW120626K1FKEA, ERJ-8ENF2612V, RC1206FR-0726K1L) are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original RCS3216F2612CS specification.

Q: Does package format (Tape & Reel vs. standard) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Tape & Reel packaging is standard for high-volume automated assembly. Electrical performance, reliability, and component specifications remain identical regardless of packaging format.

Q: Which substitute offers the best availability?

A: CR1206-FX-2612ELF (Bourns Inc.) offers the highest inventory level at 60,891 pieces in stock, followed by ERJ-8ENF2612V (Panasonic) at 46,543 pieces and RC1206FR-0726K1L (YAGEO) at 26,925 pieces. CRCW120626K1FKEA (Vishay Dale) has 12,367 pieces available.
