Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F1583CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 158 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these core requirements. Variations in physical dimensions (length, width, height) within standard 1206 package tolerances and differences in specific features (such as automotive AEC-Q200 certification or anti-sulfur coating) do not affect functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW1206158KFKEA (Vishay Dale) and RC1206FR-07158KL (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status, ensuring long-term availability and continued manufacturer support. CRCW1206158KFKEA includes automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability. RC1206FR-07158KL provides moisture-resistant thick film construction comparable to the original Samsung part.

Secondary Substitute (Legacy Status):

ERJ-8ENF1583V (Panasonic Electronic Components) is electrically and mechanically equivalent but carries a "Not For New Designs" product status. This part is suitable for replacement in existing applications or repair scenarios where inventory availability is prioritized, but should not be selected for new circuit designs.

Compliance Considerations:

All substitute parts are ROHS3 Compliant and carry MSL Rating 1 (Unlimited), matching the original part's environmental and regulatory compliance profile. Selection between substitutes should be based on application requirements (automotive vs. general industrial), long-term availability needs, and existing supply chain relationships.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206158KFKEA replace RCS3216F1583CS in any application?

A: Yes. Both parts share identical electrical specifications (158 kOhms ±1%, 0.25W, ±100ppm/°C), operate across the same temperature range (-55°C to 155°C), and use the same 1206 package. The CRCW1206158KFKEA includes automotive AEC-Q200 certification, which provides additional qualification but does not prevent use in general industrial applications.

Q: What is the difference between the anti-sulfur coating on RCS3216F1583CS and the automotive AEC-Q200 rating on CRCW1206158KFKEA?

A: Anti-sulfur coating and AEC-Q200 certification address different environmental concerns. Anti-sulfur coating protects against sulfur-containing atmospheric corrosion. AEC-Q200 is an automotive qualification standard covering reliability, temperature cycling, and performance consistency. Both are protective features; selection depends on the specific environmental exposure of the application.

Q: Why is ERJ-8ENF1583V marked "Not For New Designs"?

A: "Not For New Designs" indicates that Panasonic has discontinued active development and marketing of this part number. While the part remains functionally equivalent and is available in inventory (46940 pieces), manufacturers typically apply this status when transitioning to newer product lines. For new circuit designs, CRCW1206158KFKEA or RC1206FR-07158KL are preferred to ensure long-term supply continuity.

Q: Are there physical dimension differences between these substitute parts?

A: Minor variations exist within standard 1206 package tolerances. RCS3216F1583CS measures 0.126" L × 0.063" W with 0.026" max height. RC1206FR-07158KL measures 0.122" L × 0.063" W with 0.026" max height. CRCW1206158KFKEA measures 0.126" L × 0.063" W with 0.024" max height. These differences fall within standard 1206 package specifications and do not affect PCB layout or assembly compatibility.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes. All substitute parts use identical 1206 (3216 Metric) package specifications with 2 terminations, compatible with standard SMD pick-and-place equipment and reflow soldering processes. Tape & Reel (TR) packaging is available for all substitutes, supporting high-volume automated assembly workflows.

Q: Which substitute offers the best long-term availability?

A: RC1206FR-07158KL (YAGEO) and CRCW1206158KFKEA (Vishay Dale) both maintain Active product status with substantial inventory levels (14386 and 15022 pieces respectively). Both manufacturers are established suppliers with global distribution networks, supporting consistent long-term availability for production and replacement applications.
