RMC1/8K1872FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8K1872FTP is an 18.7 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Kamaya Inc. This component is classified as Active product status with unlimited moisture sensitivity level (MSL 1). Substitute parts are necessary when the primary part becomes unavailable, when design requirements mandate specific manufacturer certifications such as AEC-Q200 automotive qualification, or when alternative sourcing improves supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K1872FTP is determined by strict electrical and mechanical parameter matching:

Mandatory Matching Parameters:

• Resistance value: 18.7 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• Number of terminations: 2

All four substitute parts meet these mandatory criteria. Dimensional variations within supplier device package specifications (1206) are acceptable. Additional certifications such as AEC-Q200 automotive qualification represent enhanced capabilities and do not disqualify substitution. Product status variations (Active, Not For New Designs, Discontinued) reflect supply and design lifecycle considerations but do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Applications: RC1206FR-0718K7L (YAGEO) and RMCF1206FT18K7 (Stackpole) are both classified as Active products. RC1206FR-0718K7L features moisture-resistant construction. RMCF1206FT18K7 carries AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability.

For Automotive Applications: RMCF1206FT18K7 (Stackpole) and ERJ-8ENF1872V (Panasonic) both meet AEC-Q200 automotive standards. RMCF1206FT18K7 maintains Active product status, while ERJ-8ENF1872V is classified as Not For New Designs.

For RoHS3 Compliance: All substitute parts except the main part RMC1/8K1872FTP are explicitly ROHS3 compliant. This certification is relevant for applications subject to environmental regulations.

For Supply Chain Continuity: MCR18ERTF1872 (Rohm) is discontinued at DiGi Electronics and should not be selected for new designs requiring long-term availability. ERJ-8ENF1872V (Panasonic) is marked Not For New Designs and similarly should be avoided for new product development.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF1872V substitute for RMC1/8K1872FTP in new designs?

A: ERJ-8ENF1872V meets all electrical and mechanical parameters for direct substitution. However, it is classified as Not For New Designs. Selection depends on design lifecycle requirements. For new product development, RC1206FR-0718K7L or RMCF1206FT18K7 are preferred alternatives with Active product status.

Q: What is the significance of AEC-Q200 certification on RMCF1206FT18K7 and ERJ-8ENF1872V?

A: AEC-Q200 is an automotive industry qualification standard. These parts are suitable for automotive applications requiring enhanced reliability testing and qualification. Non-automotive applications do not require this certification, and its presence does not affect substitution eligibility for general-purpose circuits.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within the 1206 package specification. RMC1/8K1872FTP, RC1206FR-0718K7L measure 0.122" L x 0.063" W (3.10mm x 1.60mm). ERJ-8ENF1872V and RMCF1206FT18K7 measure 0.126" L x 0.063" W (3.20mm x 1.60mm). MCR18ERTF1872 measures 0.120" L x 0.061" W (3.05mm x 1.55mm). All variations fall within standard 1206 package tolerances and are compatible with standard PCB footprints.

Q: Why is MCR18ERTF1872 listed as a substitute if it is discontinued?

A: MCR18ERTF1872 is included in the substitute list because it meets all electrical and mechanical parameters. However, its discontinued status makes it unsuitable for new designs or applications requiring long-term component availability. Existing inventory may be available through secondary distributors for legacy system repairs.

Q: What packaging options are available among the substitutes?

A: RMC1/8K1872FTP, ERJ-8ENF1872V, RC1206FR-0718K7L, and RMCF1206FT18K7 are supplied in Tape & Reel (TR) packaging. MCR18ERTF1872 is available in Cut Tape (CT) & Digi-Reel® packaging. Tape & Reel packaging is standard for high-volume automated assembly. Cut Tape is suitable for lower-volume or manual assembly applications.

Q: Is moisture resistance a critical factor for substitution?

A: RC1206FR-0718K7L features moisture-resistant construction. All parts, including the main part RMC1/8K1872FTP, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. Moisture resistance is an additional feature on RC1206FR-0718K7L but is not a mandatory substitution criterion.
