Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K1802FTP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 18 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Number of Terminations: 2 (exact match required)

Acceptable Variation Parameters:

• Manufacturer identity (different manufacturers permitted)
• Packaging format (Tape & Reel or Cut Tape acceptable)
• Physical dimensions within 1206 package tolerance
• Height seated maximum (minor variations acceptable within package class)
• Product series designation (RMC, CRG, ERJ-8EN, KTR, RC_L, RMCF series all acceptable)
• Additional features (Automotive AEC-Q200, High Voltage, Moisture Resistant) permitted as enhancements
• RoHS and REACH compliance status (variations acceptable)

All identified substitute parts meet these criteria and are direct functional equivalents for the RMC1/8K1802FTP.

Engineering Selection Recommendations

Primary Selection (Active Status, Standard Application):

• CRG1206F18K (TE Connectivity): Active product status with 20,533 units in stock. ROHS3 compliant. Suitable for general-purpose applications without automotive requirements.
• KTR18EZPF1802 (Rohm Semiconductor): Active product status with 33,800 units in stock. Includes Automotive AEC-Q200 qualification and High Voltage features. ROHS3 compliant. Recommended for automotive or high-reliability applications.
• RMCF1206FT18K0 (Stackpole Electronics): Active product status with 10,579 units in stock. Automotive AEC-Q200 qualified. ROHS3 compliant. Suitable for automotive circuit designs.

Secondary Selection (Active Status, Specialized Features):

• RC1206FR-0718KL (YAGEO): Active product status with 5,400 units in stock. Includes Moisture Resistant feature. ROHS3 compliant. Suitable for applications requiring enhanced moisture protection.

Not Recommended for New Designs:

• ERJ-8ENF1802V (Panasonic): Product status listed as "Not For New Designs." Although electrically equivalent and Automotive AEC-Q200 qualified, this part should not be selected for new circuit designs. Existing designs currently using this part may continue operation.

All substitute parts listed are electrically and mechanically equivalent to the RMC1/8K1802FTP and provide direct replacement capability within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RMC1/8K1802FTP with any of the listed parts in my existing circuit?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They share identical resistance value (18 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). Direct substitution is functionally compatible.

Q: What is the difference between the standard parts and the automotive-qualified parts?

A: The automotive-qualified parts (KTR18EZPF1802, ERJ-8ENF1802V, RMCF1206FT18K0) carry Automotive AEC-Q200 certification, indicating they meet automotive industry reliability and quality standards. These parts are suitable for automotive applications. Non-automotive parts (CRG1206F18K, RC1206FR-0718KL) are suitable for general-purpose and industrial applications. Selection depends on application requirements, not electrical performance.

Q: Does the KTR18EZPF1802 "High Voltage" feature affect substitution compatibility?

A: No. The High Voltage feature is an additional capability that does not affect basic electrical equivalence. The KTR18EZPF1802 remains a direct substitute for the RMC1/8K1802FTP. The High Voltage feature provides enhanced performance in high-voltage applications but does not change the component's fundamental electrical characteristics or package compatibility.

Q: Why is the ERJ-8ENF1802V marked "Not For New Designs"?

A: The ERJ-8ENF1802V carries a "Not For New Designs" product status designation from Panasonic. This indicates the manufacturer is phasing out this part number. While it remains electrically equivalent and functionally compatible, it should not be selected for new circuit designs. Existing designs currently using this part may continue operation without modification.

Q: Are there packaging format differences between these substitute parts?

A: Yes. Most substitute parts are supplied in Tape & Reel (TR) format. The RC1206FR-0718KL is supplied in Cut Tape (CT) & Digi-Reel® format. Both packaging formats are compatible with standard pick-and-place assembly equipment. Selection between formats depends on manufacturing process requirements and inventory management practices.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. These parts do not require special moisture-controlled storage or handling procedures. Standard warehouse storage conditions are acceptable for all listed parts.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts are ROHS3 compliant. The RMC1/8K1802FTP RoHS status was not specified in the provided data. All identified substitutes meet current RoHS3 environmental compliance requirements.
