RMCS1206FT18K7 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT18K7 is an 18.7 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This anti-sulfur resistor is actively produced and RoHS3 compliant. Equivalent and substitute parts are necessary when the primary part experiences supply constraints, when specific certifications or compliance requirements must be met, or when design requirements mandate particular performance characteristics such as automotive qualification or moisture resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT18K7 is determined by strict equivalence across the following parameters: resistance value (18.7 kOhms), tolerance (±1%), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All identified substitute parts meet these core electrical and mechanical requirements. Substitutes are grouped by manufacturer and may differ in secondary characteristics such as automotive certification (AEC-Q200), moisture resistance features, RoHS compliance status, and packaging format (Tape & Reel vs. Cut Tape & Digi-Reel).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring RoHS3 compliance and active product status, CRCW120618K7FKEA (Vishay Dale), RC1206FR-0718K7L (YAGEO), or the original RMCS1206FT18K7 (Stackpole Electronics Inc) are suitable selections. CRCW120618K7FKEA and CRCW120618K7FKTA provide automotive AEC-Q200 qualification for applications requiring automotive-grade reliability; however, CRCW120618K7FKTA is RoHS non-compliant. RC1206FR-0718K7L offers moisture-resistant characteristics and maintains RoHS3 compliance. ERJ-8ENF1872V (Panasonic Electronic Components) carries AEC-Q200 automotive qualification and RoHS3 compliance but is designated "Not For New Designs," making it unsuitable for new product development.

Frequently Asked Questions (FAQ)

Q: Can CRCW120618K7FKEA be used as a direct replacement for RMCS1206FT18K7?

A: Yes. Both parts share identical electrical specifications (18.7 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C operating range) and the same 1206 package. CRCW120618K7FKEA adds automotive AEC-Q200 qualification and maintains RoHS3 compliance. Physical dimensions are within acceptable tolerances for PCB assembly.

Q: What is the difference between CRCW120618K7FKEA and CRCW120618K7FKTA?

A: Both are Vishay Dale 18.7 kOhms ±1% 1206 resistors with AEC-Q200 automotive qualification. The primary difference is RoHS compliance: CRCW120618K7FKEA is RoHS3 compliant, while CRCW120618K7FKTA is RoHS non-compliant. Selection depends on regulatory and compliance requirements of the end application.

Q: Why is ERJ-8ENF1872V marked "Not For New Designs"?

A: ERJ-8ENF1872V is a legacy product from Panasonic Electronic Components. While electrically equivalent and AEC-Q200 qualified, its "Not For New Designs" status indicates the manufacturer is phasing out this part number. New designs should use actively produced alternatives such as CRCW120618K7FKEA or RC1206FR-0718K7L.

Q: Does RC1206FR-0718K7L moisture resistance provide additional protection compared to RMCS1206FT18K7?

A: RC1206FR-0718K7L is specified with moisture-resistant characteristics, while RMCS1206FT18K7 features anti-sulfur protection. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating. The moisture-resistant feature of RC1206FR-0718K7L may provide enhanced performance in high-humidity environments, though both are suitable for standard industrial applications.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are available in Tape & Reel (TR) packaging. CRCW120618K7FKEA is also available in Cut Tape (CT) & Digi-Reel format. Packaging selection should align with assembly process requirements and inventory management practices.

Q: What compliance certifications are common across all parts?

A: All parts operate within -55°C ~ 155°C temperature range, maintain MSL 1 (Unlimited) moisture sensitivity, and are classified under ECCN EAR99 and HTSUS 8533.21.0030. RoHS and REACH compliance varies by manufacturer and specific part number.
