RMC1/10K2102FTP Equivalent & Substitute Parts Reference

Part Overview

The RMC1/10K2102FTP is a 21 kOhms ±1% 0.125W thick film chip resistor manufactured by Kamaya Inc. in 0805 (2012 Metric) surface mount package format. This component is currently active in production with 807 pieces available in new original stock condition. The part is supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain constraints require alternative sourcing, or when design requirements specify components with enhanced certifications such as automotive qualification (AEC-Q200) or moisture-resistant construction.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/10K2102FTP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 21 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package / Case: 0805 (2012 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 substitute parts listed below meet these mandatory parameters. Additional features such as automotive AEC-Q200 qualification or moisture-resistant construction represent enhancements that do not prevent substitution but may provide additional design margin or compliance benefits for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, High Inventory):

RMCF0805FT21K0 (Stackpole Electronics Inc) and RC0805FR-0721KL (YAGEO) are recommended as primary substitutes. Both parts are active in production with substantial inventory availability (71,810 and 121,599 pieces respectively). RMCF0805FT21K0 carries automotive AEC-Q200 qualification, suitable for applications requiring enhanced reliability standards. RC0805FR-0721KL features moisture-resistant construction, appropriate for environments with elevated humidity exposure.

Secondary Substitutes (Active Status, Specialized Features):

ERJ-6ENF2102V (Panasonic Electronic Components) and RMCF0805FG21K0 (Stackpole Electronics Inc) provide automotive AEC-Q200 qualification with active product status. KTR10EZPF2102 (Rohm Semiconductor) combines AEC-Q200 qualification with high-voltage capability, suitable for applications requiring both automotive reliability and elevated voltage performance.

Discontinued Part (Not Recommended for New Designs):

MCR10ERTF2102 (Rohm Semiconductor) is discontinued at DiGi Electronics and should not be selected for new designs despite meeting all electrical and mechanical parameters.

All substitute parts are RoHS3 compliant and REACH unaffected, matching the regulatory status of the primary part.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF2102V replace RMC1/10K2102FTP in all applications?

A: Yes. ERJ-6ENF2102V meets all mandatory electrical and mechanical parameters: 21 kOhms ±1%, 0.125W power rating, 0805 package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The automotive AEC-Q200 qualification is an additional feature that does not prevent substitution.

Q: What is the difference between RMCF0805FT21K0 and RMCF0805FG21K0?

A: Both parts are manufactured by Stackpole Electronics Inc with identical electrical specifications (21 kOhms ±1%, 0.125W, 0805 package, thick film, ±100ppm/°C, -55°C to 155°C). Both carry AEC-Q200 qualification. The difference lies in the product line designation (FT vs. FG series). Both are functionally equivalent substitutes.

Q: Why is RC0805FR-0721KL listed as a substitute if it has moisture-resistant features?

A: Moisture-resistant construction is an enhancement feature that does not alter the core electrical or mechanical parameters. RC0805FR-0721KL maintains the same 21 kOhms ±1% resistance, 0.125W power rating, 0805 package, and operating temperature range. The moisture-resistant property provides additional design margin in humid environments without compromising substitution compatibility.

Q: Is MCR10ERTF2102 suitable for new designs?

A: No. Although MCR10ERTF2102 meets all electrical and mechanical parameters, it is discontinued at DiGi Electronics. New designs should select from active parts: RMCF0805FT21K0, RC0805FR-0721KL, ERJ-6ENF2102V, RMCF0805FG21K0, or KTR10EZPF2102.

Q: What packaging formats are available for these substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) packaging except MCR10ERTF2102, which is available in Cut Tape (CT) & Digi-Reel® format. TR packaging is standard for automated assembly processes and is the primary format for active parts.

Q: Do all substitutes have the same physical dimensions?

A: All substitutes share the same 0805 (2012 Metric) package designation with dimensions 0.079" L x 0.049" W (2.00mm x 1.25mm). Height-seated maximum values range from 0.024" to 0.028" (0.60mm to 0.70mm), which falls within standard PCB assembly tolerances and does not affect interchangeability.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and REACH unaffected, matching the regulatory compliance of the primary part RMC1/10K2102FTP.
