RMC1/8K7151FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8K7151FTP is a 7.15 kOhms ±1% 0.25W thick film chip resistor manufactured by Kamaya Inc. in 1206 (3216 Metric) surface mount package. This component is currently Active in product status with 832 pieces in stock. Substitute parts are necessary when the primary part becomes unavailable, when design requirements mandate specific certifications such as AEC-Q200 automotive qualification, or when alternative manufacturers offer equivalent electrical and mechanical specifications within the same package footprint.

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K7151FTP is determined by strict equivalence across the following parameters: resistance value (7.15 kOhms), tolerance (±1%), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and MSL rating (1). All substitute parts listed meet these core electrical and mechanical requirements. Dimensional variations within the 1206 package specification are acceptable. Product status and compliance certifications (RoHS3, AEC-Q200) are secondary factors that influence selection based on application requirements but do not disqualify substitution eligibility.

Engineering Selection Recommendations

Primary Substitutes (Active Status): RC1206FR-077K15L (YAGEO) and RMCF1206FG7K15 / RMCF1206FT7K15 (Stackpole Electronics Inc) are recommended as primary substitutes. All three maintain Active product status, ensuring long-term availability and supply chain stability. RC1206FR-077K15L includes moisture-resistant construction. RMCF1206FG7K15 and RMCF1206FT7K15 carry AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability.

Secondary Substitutes (Limited Availability): ERJ-8ENF7151V (Panasonic) is marked "Not For New Designs" and carries AEC-Q200 certification. This part is suitable only for legacy system maintenance or repair applications where automotive qualification is mandatory. MCR18ERTF7151 (Rohm Semiconductor) is discontinued at DiGi Electronics and should be avoided for new designs despite current inventory availability.

Compliance Considerations: All listed parts are RoHS3 compliant and REACH unaffected. MSL rating of 1 (Unlimited) applies uniformly across all parts, indicating no moisture sensitivity restrictions during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FG7K15 or RMCF1206FT7K15 be used as direct replacements for RMC1/8K7151FTP?

A: Yes. Both Stackpole parts meet all electrical specifications (7.15 kΩ, ±1%, 0.25W) and package requirements (1206). The primary difference is AEC-Q200 automotive certification, which adds qualification value without compromising general-purpose applications. Dimensional tolerances remain within 1206 package specification.

Q: What is the difference between RMCF1206FG7K15 and RMCF1206FT7K15?

A: Both parts are manufactured by Stackpole Electronics Inc with identical electrical specifications and AEC-Q200 certification. The difference lies in internal construction or manufacturing process designation (FG vs. FT suffix). Both are functionally equivalent for circuit applications.

Q: Is RC1206FR-077K15L suitable for high-humidity environments?

A: RC1206FR-077K15L includes moisture-resistant construction as a specified feature. Combined with MSL rating of 1 (Unlimited), this part is suitable for high-humidity environments without additional protective measures.

Q: Why is ERJ-8ENF7151V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active promotion of this part for new circuit designs. Existing inventory remains available for legacy system support and repair. New designs should prioritize Active-status alternatives such as RMCF1206FG7K15 or RC1206FR-077K15L.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification. The main part (RMC1/8K7151FTP) does not specify RoHS status in the provided data but is compatible with RoHS3-compliant substitute parts in circuit assembly.

Q: Can MCR18ERTF7151 be used despite discontinuation status?

A: MCR18ERTF7151 is discontinued at DiGi Electronics and should not be selected for new designs. Current inventory (12,206 pieces) may support short-term legacy applications, but long-term supply cannot be assured. Active alternatives are strongly preferred.
