RCS3216F1581CS Equivalent & Substitute Parts

Part Overview

The RCS3216F1581CS is a 1.58 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 a temperature coefficient of ±100ppm/°C. The component is RoHS3 compliant with MSL 1 (Unlimited) rating and is currently in active production status with 1096 pieces available in stock.

Substitute parts are identified when they maintain identical electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package type, dimensions, termination count) while meeting the same environmental and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1581CS is determined by strict adherence to the following criteria:

Electrical Parameters (Must Match Exactly):

• Resistance value: 1.58 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

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

Compliance Parameters (Must Match or Exceed):

• RoHS3 compliance
• MSL 1 (Unlimited) rating
• REACH Unaffected status

All four substitute parts listed meet these criteria across all electrical, mechanical, and compliance dimensions. Variations in physical dimensions (length, width, height) and packaging format (Tape & Reel) do not affect functional substitutability when all core parameters align.

Engineering Selection Recommendations

Primary Selection (Active Status):

CR1206-FX-1581ELF (Bourns Inc.) and RC1206FR-071K58L (YAGEO) are recommended as primary substitutes. Both maintain active production status and full compliance with RoHS3 and REACH requirements. Bourns CR1206-FX-1581ELF offers 24,614 pieces in stock inventory. YAGEO RC1206FR-071K58L provides 6,370 pieces in stock. Both are supplied in Tape & Reel packaging format.

Secondary Selection (Automotive-Qualified):

CRCW12061K58FKEA (Vishay Dale) is qualified to AEC-Q200 automotive standards with 17,620 pieces in stock. This part is suitable for applications requiring automotive-grade reliability certification while maintaining identical electrical and mechanical specifications.

Legacy Status Consideration:

ERJ-8ENF1581V (Panasonic Electronic Components) carries "Not For New Designs" product status despite meeting all electrical and mechanical criteria. This part is available with 41,492 pieces in stock and maintains AEC-Q200 qualification. Selection of this part should be limited to replacement or maintenance applications for existing designs only.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-1581ELF replace RCS3216F1581CS in existing designs?

A: Yes. CR1206-FX-1581ELF meets all electrical specifications (1.58 kOhms ±1%, 0.25W), operates across the identical temperature range (-55°C ~ 155°C), maintains the same package footprint (1206/3216 Metric), and holds equivalent RoHS3 and MSL 1 compliance. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between the anti-sulfur feature in RCS3216F1581CS and moisture-resistant features in substitute parts?

A: The provided specifications indicate RCS3216F1581CS includes anti-sulfur and moisture-resistant properties, while CR1206-FX-1581ELF and RC1206FR-071K58L specify moisture-resistant properties. All substitute parts maintain MSL 1 (Unlimited) rating. Functional performance across the specified operating temperature range and environmental conditions remains equivalent based on provided parameters.

Q: Are there packaging differences between the main part and substitutes?

A: RCS3216F1581CS packaging format is not specified in the provided data. Substitute parts CR1206-FX-1581ELF, CRCW12061K58FKEA, ERJ-8ENF1581V, and RC1206FR-071K58L are supplied in Tape & Reel (TR) format. Physical dimensions show minor variations: length ranges from 0.122" to 0.126" (3.10mm to 3.20mm) and height from 0.024" to 0.030" (0.60mm to 0.75mm). These variations remain within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: Why is ERJ-8ENF1581V marked "Not For New Designs"?

A: ERJ-8ENF1581V carries "Not For New Designs" status from Panasonic Electronic Components. This designation indicates the manufacturer is transitioning this product line. For new design implementations, CR1206-FX-1581ELF, CRCW12061K58FKEA, or RC1206FR-071K58L are preferred selections. ERJ-8ENF1581V remains suitable for replacement applications in existing designs.

Q: Do all substitute parts meet automotive qualification requirements?

A: CRCW12061K58FKEA and ERJ-8ENF1581V hold AEC-Q200 automotive qualification. CR1206-FX-1581ELF and RC1206FR-071K58L do not specify AEC-Q200 rating in the provided data. Selection should be based on application requirements: automotive-qualified parts are necessary for automotive applications; general industrial applications can use any of the four substitutes.

Q: What inventory considerations apply to part selection?

A: Current stock levels are: RCS3216F1581CS (1,096 pcs), CR1206-FX-1581ELF (24,614 pcs), CRCW12061K58FKEA (17,620 pcs), ERJ-8ENF1581V (41,492 pcs), RC1206FR-071K58L (6,370 pcs). Availability should be evaluated against project lead time and volume requirements.
