RMC1/8K1503FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8K1503FTP is a 150 kOhms ±1% 0.25W thick film chip resistor manufactured by Kamaya Inc. in 1206 (3216 Metric) surface mount package format. This component is currently active in production and available in tape and reel packaging. Substitute parts are necessary when the primary part experiences supply constraints, inventory depletion, or when design requirements mandate alternative manufacturer specifications or certifications such as automotive AEC-Q200 compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RMC1/8K1503FTP is determined by strict equivalence across the following parameters: resistance value (150 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 substitute parts listed maintain these core electrical and mechanical specifications. Dimensional variations within the 1206 package envelope are acceptable per IEC 60603-7 standards. Substitute parts may include additional features such as automotive AEC-Q200 certification or moisture-resistant construction, which do not prevent functional equivalence but may provide enhanced performance for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Highest Availability)

CRG1206F150K (TE Connectivity) and RMCF1206FT150K (Stackpole Electronics Inc) are recommended as primary substitutes. Both parts maintain active product status, are available in tape and reel packaging suitable for automated assembly, and demonstrate high inventory levels (19,830 and 98,599 units respectively). Both are RoHS3 compliant and REACH unaffected.

Automotive-Qualified Alternatives

KTR18EZPF1503 (Rohm Semiconductor) and RMCF1206FG150K (Stackpole Electronics Inc) include AEC-Q200 automotive qualification and are suitable for applications requiring automotive-grade reliability. KTR18EZPF1503 additionally features high voltage capability. Both maintain active product status with substantial inventory availability.

Moisture-Resistant Option

RC1206FR-07150KL (YAGEO) provides moisture-resistant thick film construction and is available in high volume (212,273 units). This part is suitable for applications in humid or corrosive environments while maintaining active product status.

Parts to Avoid for New Designs

ERJ-8ENF1503V (Panasonic) carries "Not For New Designs" status and should not be selected for new product development. MCR18ERTF1503 (Rohm Semiconductor) is discontinued at DiGi Electronics and should be avoided due to limited future availability.

Frequently Asked Questions (FAQ)

Q: Can I substitute RMC1/8K1503FTP with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts maintain identical resistance (150 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The 1206 package is standardized across all parts. Direct substitution is electrically and mechanically valid.

Q: What is the difference between tape and reel packaging and cut tape packaging?

A: Tape and reel packaging is supplied on continuous carrier tape wound on reels, optimized for high-volume automated assembly. Cut tape and Digi-Reel packaging is supplied in shorter tape segments on plastic reels, suitable for lower-volume or manual assembly. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Why do some substitute parts have AEC-Q200 certification?

A: AEC-Q200 is an automotive industry qualification standard. Parts with this certification have undergone additional reliability testing and are suitable for automotive applications. Non-certified parts are equally suitable for general industrial and consumer applications. AEC-Q200 certification does not affect electrical performance for non-automotive use.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within the 1206 package specification. Length ranges from 0.120" to 0.126" (3.05mm to 3.20mm), width from 0.061" to 0.063" (1.55mm to 1.60mm), and height from 0.025" to 0.028" (0.65mm to 0.70mm). These variations are within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Which substitute part has the highest inventory availability?

A: RMCF1206FT150K (Stackpole Electronics Inc) has the highest inventory level at 98,599 units, followed by RC1206FR-07150KL (YAGEO) at 212,273 units. For immediate availability, RC1206FR-07150KL is the optimal choice.

Q: Can I use ERJ-8ENF1503V or MCR18ERTF1503 in existing designs?

A: ERJ-8ENF1503V carries "Not For New Designs" status but may be used in existing production if already qualified. MCR18ERTF1503 is discontinued at DiGi Electronics and should not be used due to supply uncertainty. For ongoing production, select from active-status alternatives.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. The component does not require special dry-pack storage or baking procedures prior to assembly, simplifying inventory management and reducing handling costs.
