Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/10K2491FTP is determined by the following critical parameters:

Electrical Specifications: Resistance value of 2.49 kOhms, tolerance of ±1%, and power rating of 0.125W (1/8W) must match exactly. Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C establish thermal performance boundaries.

Mechanical & Package Specifications: Package type must be 0805 (2012 Metric) with identical physical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Height seated maximum of 0.026" (0.65mm) or less ensures PCB assembly compatibility. Two terminations are required.

Material & Composition: Thick film construction is the specified composition type.

Environmental & Compliance: Moisture Sensitivity Level 1 (Unlimited), REACH Unaffected status, and EAR99 ECCN classification apply to all qualified substitutes.

All four substitute parts listed meet these criteria and are therefore direct functional equivalents for the RMC1/10K2491FTP.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are Active status components with full electrical and mechanical compatibility to the RMC1/10K2491FTP. Selection among these equivalents may be based on the following factors:

Automotive Applications: ERJ-6ENF2491V (Panasonic ERJ-6EN series), KTR10EZPF2491 (Rohm KTR series), and RMCF0805FT2K49 (Stackpole RMCF series) carry AEC-Q200 automotive qualification ratings. These parts are suitable for automotive-grade circuit designs.

High Voltage Applications: KTR10EZPF2491 includes high voltage capability in addition to AEC-Q200 compliance.

Moisture Resistance: RC0805FR-072K49L (YAGEO RC_L series) features moisture-resistant construction.

Packaging Format: RMC1/10K2491FTP, KTR10EZPF2491, RC0805FR-072K49L, and RMCF0805FT2K49 are supplied in Tape & Reel (TR) format. ERJ-6ENF2491V is supplied in Cut Tape (CT) & Digi-Reel® format.

Physical Height: RC0805FR-072K49L has the lowest seated height at 0.024" (0.60mm), while ERJ-6ENF2491V has the highest at 0.028" (0.70mm). All remain within standard 0805 package specifications.

Inventory Availability: RMCF0805FT2K49 (135,998 pcs), ERJ-6ENF2491V (135,274 pcs), and RC0805FR-072K49L (25,400 pcs) offer substantial stock levels. KTR10EZPF2491 (1,861 pcs) and RMC1/10K2491FTP (1,103 pcs) have more limited availability.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF2491V replace RMC1/10K2491FTP directly?

A: Yes. ERJ-6ENF2491V meets all electrical specifications (2.49 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C) and mechanical requirements (0805 package, 2-termination). The seated height of 0.028" (0.70mm) is within acceptable 0805 package tolerance. Panasonic ERJ-6EN series is AEC-Q200 qualified, providing additional automotive-grade assurance.

Q: What is the difference between KTR10EZPF2491 and other substitutes?

A: KTR10EZPF2491 includes both AEC-Q200 automotive qualification and high voltage capability. This makes it suitable for applications requiring enhanced voltage performance beyond standard general-purpose resistor specifications. All other electrical and mechanical parameters remain identical to other substitutes.

Q: Why does RC0805FR-072K49L have a lower seated height?

A: RC0805FR-072K49L has a maximum seated height of 0.024" (0.60mm) compared to 0.026" (0.65mm) for most other substitutes. This is within normal manufacturing variation for 0805 package components and does not affect functional compatibility. The moisture-resistant feature of the YAGEO RC_L series may provide additional environmental protection in specific applications.

Q: Are all substitutes RoHS3 compliant?

A: ERJ-6ENF2491V, KTR10EZPF2491, RC0805FR-072K49L, and RMCF0805FT2K49 are all ROHS3 compliant. RoHS compliance status was not specified for the original RMC1/10K2491FTP.

Q: What packaging formats are available?

A: RMC1/10K2491FTP, KTR10EZPF2491, RC0805FR-072K49L, and RMCF0805FT2K49 are supplied in Tape & Reel (TR) format. ERJ-6ENF2491V is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly equipment compatibility and procurement requirements.

Q: Do all substitutes have MSL 1 rating?

A: Yes. All substitute parts and the original RMC1/10K2491FTP carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity restrictions for storage and handling.

Q: Can I use these substitutes interchangeably in production?

A: All four substitutes are electrically and mechanically equivalent to RMC1/10K2491FTP and meet identical core specifications. Interchangeability depends on specific application requirements such as automotive qualification needs, packaging format compatibility with assembly equipment, and inventory availability. Consult design documentation and procurement specifications for your application.
