RMC1/8-1102FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8-1102FTP is an 11 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 809 pieces currently in stock. The RMC series represents a standard general-purpose resistor suitable for industrial and commercial applications. Substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative certifications are required for specific applications, or when design requirements necessitate enhanced features such as automotive qualification or moisture resistance.

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8-1102FTP is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

Resistance Value: 11 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)
Moisture Sensitivity Level: MSL 1 (Unlimited) (exact match required)

Acceptable Variations:

Manufacturer identity (different suppliers permitted)
Packaging format (Tape & Reel or Cut Tape acceptable)
Product status (Active or Not For New Designs both acceptable for substitution purposes)
Dimensional tolerances within supplier specifications (minor variations in length, width, height acceptable within standard manufacturing tolerances)
Additional certifications or features (AEC-Q200 automotive qualification, moisture resistance, high voltage capability) are additive and do not disqualify substitution

All six substitute parts listed meet these mandatory matching criteria and are therefore direct electrical and mechanical equivalents to the RMC1/8-1102FTP.

Engineering Selection Recommendations

For General Industrial Applications (Non-Automotive): Select from CRG1206F11K (TE Connectivity), RC1206FR-0711KL (YAGEO), or the original RMC1/8-1102FTP (Kamaya). All three maintain Active product status and provide equivalent electrical performance. RC1206FR-0711KL offers the advantage of moisture-resistant construction and highest inventory availability (131,629 pieces). CRG1206F11K provides ROHS3 compliance with comparable inventory levels (801 pieces).

For Automotive Applications: Select RMCF1206FT11K0 (Stackpole Electronics Inc) or KTR18EZPF1102 (Rohm Semiconductor). Both carry AEC-Q200 automotive qualification and Active product status. RMCF1206FT11K0 offers higher inventory (22,848 pieces) compared to KTR18EZPF1102 (10,257 pieces). KTR18EZPF1102 provides additional high-voltage capability if required by circuit design.

For High-Reliability or Legacy System Maintenance: ERJ-8ENF1102V (Panasonic Electronic Components) is acceptable despite "Not For New Designs" status, as it carries AEC-Q200 qualification and maintains the highest inventory availability (167,441 pieces). This part is suitable for replacement in existing systems or production runs already qualified to this component.

Avoid: MCR18ERTF1102 (Rohm Semiconductor) is listed as "Discontinued at DiGi Electronics" and should not be selected for new designs or long-term production requirements, despite current inventory availability (953 pieces).

Compliance Considerations: All substitute parts except the original RMC1/8-1102FTP carry explicit ROHS3 compliance certification. If ROHS3 compliance is a design requirement, select from the six substitute parts. The original RMC1/8-1102FTP does not specify RoHS status and should be verified with Kamaya Inc. if compliance is mandatory.

Frequently Asked Questions (FAQ)

Q: Can I substitute RMC1/8-1102FTP with any of the listed parts without circuit redesign?

A: Yes. All six substitute parts are direct electrical and mechanical equivalents. They share identical resistance value (11 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). No circuit redesign is required for substitution.

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

A: Automotive-qualified parts (ERJ-8ENF1102V, KTR18EZPF1102, RMCF1206FT11K0) carry AEC-Q200 certification, indicating compliance with automotive industry reliability and quality standards. General-purpose parts (RMC1/8-1102FTP, CRG1206F11K, RC1206FR-0711KL, MCR18ERTF1102) do not carry this certification. Automotive qualification is required only if the component will be used in automotive applications or systems subject to automotive supply chain requirements.

Q: Why does RC1206FR-0711KL have "moisture resistant" as a feature while others do not?

A: RC1206FR-0711KL from YAGEO incorporates moisture-resistant construction as an additional manufacturing feature. This does not affect substitution eligibility, as all parts meet the same MSL 1 (Unlimited) moisture sensitivity rating. The moisture-resistant feature is additive and provides enhanced protection in high-humidity environments, but is not required for standard substitution.

Q: What does "Not For New Designs" mean for ERJ-8ENF1102V?

A: "Not For New Designs" indicates that Panasonic has designated this part as legacy or end-of-life for new product development. However, it remains a valid substitute for existing designs, maintenance, or production runs already qualified to this component. For new designs, select from parts with Active status: CRG1206F11K, KTR18EZPF1102, RC1206FR-0711KL, or RMCF1206FT11K0.

Q: Are there dimensional differences between the substitute parts?

A: Minor dimensional variations exist within standard manufacturing tolerances. 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 acceptable PCB assembly tolerances and do not affect substitution. Verify specific dimensions with your PCB design if tight mechanical constraints exist.

Q: Which substitute part has the best inventory availability?

A: RC1206FR-0711KL (YAGEO) offers the highest inventory availability with 131,629 pieces in stock, followed by ERJ-8ENF1102V (Panasonic) with 167,441 pieces. For immediate availability in high-volume production, these two parts are preferred. RMCF1206FT11K0 (Stackpole) provides 22,848 pieces with automotive qualification.

Q: Do all substitute parts have ROHS3 compliance?

A: All six substitute parts explicitly state ROHS3 compliance. The original RMC1/8-1102FTP does not specify RoHS status in the provided data. If ROHS3 compliance is a mandatory design requirement, any of the six substitute parts satisfy this requirement.

Q: Can KTR18EZPF1102 be used in high-voltage applications?

A: KTR18EZPF1102 is specified with "High Voltage" as an additional feature. However, no specific voltage rating is provided in the technical data. The high-voltage designation indicates enhanced capability compared to standard thick-film resistors, but the exact voltage limit must be obtained from Rohm Semiconductor's detailed datasheet. For applications requiring high-voltage operation, contact the manufacturer for voltage specifications.

Q: What is the REACH status, and does it affect substitution?

A: REACH status indicates compliance with European chemical regulations. The original RMC1/8-1102FTP is "REACH Unaffected," meaning it does not contain substances of concern. Most substitutes are also "REACH Unaffected" (ERJ-8ENF1102V, KTR18EZPF1102, MCR18ERTF1102, RC1206FR-0711KL, RMCF1206FT11K0). CRG1206F11K shows "Vendor Undefined" status. For applications subject to REACH compliance requirements, verify with the specific manufacturer. This does not prevent substitution but may require documentation for compliance purposes.
