RCS3216F8063CS Equivalent & Substitute Parts

Part Overview

The RCS3216F8063CS is a 806 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is currently in active production status with 954 pieces available in inventory.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements mandate specific certifications such as automotive AEC-Q200 qualification or high-voltage performance characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F8063CS is determined by strict equivalence across the following parameters:

Core Electrical Parameters:

Resistance value: 806 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C

Physical & Package Parameters:

Package type: 1206 (3216 Metric)
Number of terminations: 2

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW1206806KFKEA (Vishay Dale), KTR18EZPF8063 (Rohm), and RC1206FR-07806KL (YAGEO) are all active products with full ROHS3 compliance and unlimited MSL rating. These three parts are electrically and mechanically equivalent to the RCS3216F8063CS and are suitable for direct substitution in standard applications.

CRCW1206806KFKEA and KTR18EZPF8063 carry automotive AEC-Q200 certification, which provides additional qualification for automotive-grade applications. KTR18EZPF8063 additionally features high-voltage capability. These enhanced certifications do not prevent use in non-automotive applications.

Secondary Substitute (Not For New Designs):

ERJ-8ENF8063V (Panasonic) meets all electrical and mechanical equivalence criteria and carries AEC-Q200 certification. However, this part is designated "Not For New Designs," indicating Panasonic has discontinued active development. This part remains suitable for legacy system maintenance or replacement scenarios but should not be selected for new product designs.

Selection Basis:

All substitutes maintain identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Physical package dimensions are within acceptable variation for 1206 form factor. All parts comply with ROHS3 and maintain MSL 1 rating. Selection should prioritize active-status parts (CRCW1206806KFKEA, KTR18EZPF8063, RC1206FR-07806KL) for new designs.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206806KFKEA replace RCS3216F8063CS in any application?

A: Yes. CRCW1206806KFKEA is electrically and mechanically equivalent across all specified parameters: 806 kOhms ±1%, 0.25W power rating, 1206 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL 1 rating. The automotive AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive circuits.

Q: Why is ERJ-8ENF8063V marked "Not For New Designs"?

A: "Not For New Designs" indicates that Panasonic has transitioned this product to end-of-life status and is not actively developing or promoting it for new applications. While the part remains functionally equivalent and available in inventory (68,671 pieces), it should be reserved for legacy system support or replacement applications. New product designs should select from active-status alternatives.

Q: Are there physical dimension differences between these substitutes?

A: All parts conform to the 1206 (3216 Metric) package standard. Seated height varies slightly: RCS3216F8063CS at 0.66mm, CRCW1206806KFKEA at 0.60mm, ERJ-8ENF8063V at 0.70mm, KTR18EZPF8063 at 0.65mm, and RC1206FR-07806KL at 0.65mm. These variations fall within standard 1206 package tolerance and do not affect PCB layout or assembly compatibility.

Q: What is the difference between the anti-sulfur feature on RCS3216F8063CS and the automotive AEC-Q200 certification on CRCW1206806KFKEA?

A: Anti-sulfur protection on the RCS3216F8063CS addresses environmental corrosion from sulfur-containing compounds. Automotive AEC-Q200 certification on CRCW1206806KFKEA and other substitutes represents comprehensive qualification testing for automotive reliability, including thermal cycling, humidity, and mechanical stress. These are distinct protective mechanisms; AEC-Q200 certification does not replace anti-sulfur protection, nor does anti-sulfur protection provide automotive qualification.

Q: Can KTR18EZPF8063 be used in high-voltage applications where RCS3216F8063CS cannot?

A: KTR18EZPF8063 is specified with high-voltage capability as an additional feature. However, the input parameters do not provide voltage ratings for any part. Substitution eligibility is determined strictly by the provided parameters: resistance, tolerance, power rating, package, temperature coefficient, operating temperature, and compliance certifications. High-voltage capability represents an enhanced specification beyond the base equivalence criteria.

Q: Which substitute offers the best inventory availability?

A: ERJ-8ENF8063V has the highest inventory level at 68,671 pieces. RC1206FR-07806KL follows with 11,810 pieces. CRCW1206806KFKEA has 4,400 pieces, and KTR18EZPF8063 has 7,333 pieces. However, inventory levels are subject to change and should be verified at time of procurement.
