RCS2012F1583CS Equivalent & Substitute Parts

Part Overview

The RCS2012F1583CS is a 158 kOhms ±1% 0.125W chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package. 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 part is Active in product status and ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when components share identical electrical specifications (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical compatibility (package type, footprint, termination count) while maintaining compliance with applicable standards and certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F1583CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 158 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.125W / 1/8W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to 155°C (exact match)

Mechanical Equivalence Requirements:

• Package type: 0805 (2012 Metric) (exact match)
• Number of terminations: 2 (exact match)
• Footprint compatibility: 0.079" L x 0.049" W (2.00mm x 1.25mm) (exact match)

Compliance Requirements:

• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)
• REACH Unaffected status (required)

All three substitute parts listed meet these criteria. Variations in height (seated maximum) and specific feature sets (automotive AEC-Q200 certification, anti-sulfur properties) do not disqualify substitution when all primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the RCS2012F1583CS based on electrical and mechanical parameter alignment. Selection among these options is determined by application-specific requirements and availability:

CRCW0805158KFKEA (Vishay Dale): This substitute includes automotive AEC-Q200 certification and features a lower seated height of 0.020" (0.50mm). Selection is appropriate for applications requiring automotive-grade qualification or space-constrained PCB layouts.

ERJ-6ENF1583V (Panasonic Electronic Components): This substitute includes automotive AEC-Q200 certification with a seated height of 0.028" (0.70mm). Selection is appropriate for automotive applications requiring AEC-Q200 compliance with standard height tolerance.

RC0805FR-07158KL (YAGEO): This substitute features moisture-resistant properties matching the RCS2012F1583CS anti-sulfur and moisture-resistant characteristics, with a seated height of 0.024" (0.60mm). Selection is appropriate for general industrial applications without automotive requirements.

All parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and REACH Unaffected status. Product status is Active for all options, ensuring continued availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805158KFKEA replace RCS2012F1583CS in non-automotive applications?

A: Yes. The CRCW0805158KFKEA meets all electrical and mechanical equivalence criteria for the RCS2012F1583CS. The automotive AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive circuits. The lower seated height (0.020" vs 0.026") may provide advantages in space-constrained designs.

Q: What is the significance of the height difference between substitute parts?

A: Seated height variations (0.020" to 0.028") reflect manufacturing tolerances within the 0805 package specification. These differences are within standard PCB assembly clearance margins and do not affect electrical performance or footprint compatibility. Height selection is relevant only for applications with specific vertical space constraints.

Q: Are the automotive AEC-Q200 rated substitutes suitable for industrial applications?

A: Yes. AEC-Q200 certification represents additional qualification testing beyond standard industrial requirements. Parts meeting AEC-Q200 standards are fully compatible with industrial applications and provide enhanced reliability margins.

Q: Does the anti-sulfur feature of RCS2012F1583CS require matching in substitute parts?

A: No. Anti-sulfur and moisture-resistant properties are manufacturing enhancements that improve long-term reliability in corrosive environments. The RC0805FR-07158KL includes moisture-resistant properties; CRCW0805158KFKEA and ERJ-6ENF1583V do not specify anti-sulfur treatment. All three substitutes meet the core electrical and mechanical requirements for direct replacement.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts share identical footprint dimensions (0.079" L x 0.049" W), two terminations, and 0805 package specification. PCB layout and assembly processes require no modification for substitution.

Q: What compliance certifications are common across all parts?

A: All parts (main and substitutes) are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity level, and maintain REACH Unaffected status. These certifications ensure regulatory compliance across industrial and commercial applications.
