RCS2012F1581CS Equivalent & Substitute Parts

Part Overview

The RCS2012F1581CS is a 1.58 kOhms ±1% 0.125W chip resistor in 0805 (2012 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 and carries MSL Level 1 (Unlimited) moisture sensitivity rating. Identifying equivalent substitute parts is necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements necessitate alternative qualified sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS2012F1581CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.58 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2
• RoHS3 compliance
• MSL Level 1

All substitute parts listed meet these exact specifications. Variations in physical dimensions (height-seated) and additional certifications (such as AEC-Q200 automotive qualification) do not prevent substitution but represent enhanced or alternative feature sets.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RCS2012F1581CS, CRCW08051K58FKEA, ERJ-6ENF1581V, and RC0805FR-071K58L—are functionally equivalent for applications requiring a 1.58 kOhms ±1% 0.125W 0805 thick film resistor. Selection among these parts should be based on:

Product Status: All parts carry Active product status, ensuring continued availability and manufacturing support.

Compliance Certifications: All parts are RoHS3 compliant and REACH unaffected. The Vishay Dale CRCW08051K58FKEA and Panasonic ERJ-6ENF1581V carry additional AEC-Q200 automotive qualification, suitable for automotive and high-reliability applications. The Samsung RCS2012F1581CS and YAGEO RC0805FR-071K58L provide standard industrial-grade reliability.

Physical Dimensions: Height-seated measurements vary between 0.020" (0.50mm) and 0.028" (0.70mm). For space-constrained PCB layouts, the Vishay Dale part offers the lowest profile at 0.020" maximum height.

Inventory Availability: Panasonic ERJ-6ENF1581V shows the highest stock level at 42,401 pieces, followed by YAGEO RC0805FR-071K58L at 24,501 pieces, Vishay Dale CRCW08051K58FKEA at 10,683 pieces, and Samsung RCS2012F1581CS at 725 pieces.

Frequently Asked Questions (FAQ)

Q: Can CRCW08051K58FKEA replace RCS2012F1581CS directly?

A: Yes. Both parts share identical electrical specifications (1.58 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), package type (0805), composition (thick film), and compliance ratings (RoHS3, MSL Level 1). The Vishay Dale part includes AEC-Q200 automotive certification and has a lower maximum seated height of 0.020" compared to 0.026" for the Samsung part.

Q: What is the difference between ERJ-6ENF1581V and RC0805FR-071K58L?

A: Both parts are electrically and mechanically equivalent to the RCS2012F1581CS. The Panasonic ERJ-6ENF1581V carries AEC-Q200 automotive qualification and has a maximum seated height of 0.028", while the YAGEO RC0805FR-071K58L is standard industrial-grade with a maximum seated height of 0.024". The Panasonic part has significantly higher inventory availability.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. All four parts use the 0805 (2012 Metric) package with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). PCB layout and reflow profiles remain unchanged. Minor variations in maximum seated height (0.020" to 0.028") are within standard PCB assembly tolerances and do not affect compatibility.

Q: Which substitute part should be selected for automotive applications?

A: Both CRCW08051K58FKEA (Vishay Dale) and ERJ-6ENF1581V (Panasonic) carry AEC-Q200 automotive qualification. The Panasonic part offers superior inventory availability at 42,401 pieces. The Vishay Dale part provides a lower profile at 0.020" maximum seated height for space-constrained designs.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All four parts—RCS2012F1581CS, CRCW08051K58FKEA, ERJ-6ENF1581V, and RC0805FR-071K58L—are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
