Substitute Part Grouping Explanation

All substitute parts listed maintain identical electrical specifications: 2.4 kOhms resistance, ±1% tolerance, 0.25W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. All parts use thick film composition in 1206 (3216 Metric) surface mount packages with two terminations.

Substitution logic is based strictly on these matching parameters:

Resistance & Tolerance: All substitutes are 2.4 kOhms ±1%
Power Rating: All substitutes are rated 0.25W (1/4W)
Package: All substitutes use 1206 (3216 Metric) package
Composition: All substitutes use thick film technology
Temperature Performance: All substitutes operate -55°C to 155°C with ±100ppm/°C coefficient
Terminations: All substitutes have 2 terminations
Moisture Sensitivity: All substitutes are MSL 1 (Unlimited)

Differences among substitutes relate to manufacturer, packaging format (Tape & Reel vs. Cut Tape), product status, and optional features such as automotive AEC-Q200 qualification or moisture resistance.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Tape & Reel Packaging)

CRG1206F2K4 (TE Connectivity) and RMCF1206FT2K40 (Stackpole Electronics Inc) are recommended as primary substitutes. Both parts maintain Active product status, are supplied in Tape & Reel format matching the original packaging, and carry ROHS3 compliance. RMCF1206FT2K40 includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability.

Secondary Substitutes (Active Status, Alternative Packaging)

RC1206FR-072K4L (YAGEO) is Active with the largest inventory (174,062 pieces) and includes moisture resistance features. This part is supplied in Cut Tape & Digi-Reel format rather than standard Tape & Reel, requiring verification of assembly line compatibility.

KTR18EZPF2401 (Rohm Semiconductor) is Active and includes both automotive AEC-Q200 qualification and high voltage features. This part is supplied in Tape & Reel format.

Not Recommended for New Designs

ERJ-8ENF2401V (Panasonic Electronic Components) carries "Not For New Designs" status and should not be selected for new applications, despite meeting all electrical and mechanical parameters.

Discontinued Parts

MCR18ERTF2401 (Rohm Semiconductor) is discontinued at DiGi Electronics and should be avoided for new procurement.

Frequently Asked Questions (FAQ)

Q: Can I substitute RMC1/8K2401FTP with any of the listed parts?

A: Substitution is permissible only when all critical parameters match: 2.4 kOhms resistance, ±1% tolerance, 0.25W power rating, 1206 package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. All listed parts meet these requirements. However, product status and packaging format differences must be evaluated for your specific application and assembly process.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel packaging supplies components on cut tape segments or alternative reel formats. Verify your assembly equipment compatibility before selecting parts with different packaging formats.

Q: Why is ERJ-8ENF2401V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and support for this part number. While the part may still be available in inventory, it should not be selected for new product designs. Use Active status parts instead.

Q: Does automotive AEC-Q200 qualification matter for my application?

A: Automotive AEC-Q200 qualification is required only for automotive applications or systems requiring automotive-grade reliability standards. For non-automotive applications, this feature is optional. Parts with AEC-Q200 qualification include RMCF1206FT2K40 and KTR18EZPF2401.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts carry this rating, eliminating moisture-related procurement constraints.

Q: Can I use RC1206FR-072K4L as a direct replacement despite its moisture resistance feature?

A: Yes. The moisture resistance feature of RC1206FR-072K4L is an additional capability that does not conflict with the original part's specifications. However, verify that your assembly line equipment supports Cut Tape & Digi-Reel packaging format before selection.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance status. The original RMC1/8K2401FTP does not specify RoHS status in the provided data. Verify RoHS compliance requirements for your application before final part selection.
