Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F1872CS are classified based on strict electrical and mechanical parameter alignment. The substitution logic is determined by the following critical parameters:

Electrical Parameters:

• Resistance value: 18.7 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 0402 (1005 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of Terminations: 2 (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Power Rating Consideration: Parts are grouped into Direct Equivalent (0.063W / 1/16W) and Upgrade categories (0.1W / 1/10W or higher). Upgrade substitutes provide enhanced power dissipation capability while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitutes:

RC0402FR-0718K7L (YAGEO) is a direct equivalent substitute with identical electrical specifications, power rating, and moisture resistant construction. Both parts maintain ROHS3 compliance and MSL Level 1 rating. This substitute is suitable for direct replacement in applications where the original Samsung part is unavailable.

Upgrade Substitute:

ERJ-2RKF1872X (Panasonic Electronic Components) provides enhanced power dissipation at 0.1W (1/10W) compared to the original 0.063W rating, while maintaining all other electrical parameters. This part carries Automotive AEC-Q200 qualification. The upgrade substitute is applicable in designs where increased thermal margin is beneficial or where automotive-grade reliability is required.

Automotive-Qualified Alternatives:

AC0402FR-0718K7L (YAGEO), CRCW040218K7FKED (Vishay Dale), and RMCF0402FT18K7 (Stackpole Electronics Inc) are all Automotive AEC-Q200 qualified alternatives with identical power ratings and electrical specifications to the original part. These substitutes are suitable for applications requiring automotive-grade component qualification while maintaining the original 0.063W power rating and moisture resistant construction.

All substitute parts maintain Active product status, ROHS3 compliance, and MSL Level 1 rating consistent with the original RC1005F1872CS specification.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-0718K7L be used as a direct replacement for RC1005F1872CS?

A: Yes. RC0402FR-0718K7L meets all electrical and mechanical specifications of the original part, including 18.7 kOhms resistance, ±1% tolerance, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, moisture resistant construction, ROHS3 compliance, and MSL Level 1 rating.

Q: What is the difference between the original part and ERJ-2RKF1872X?

A: ERJ-2RKF1872X provides higher power dissipation at 0.1W (1/10W) versus the original 0.063W (1/16W). All other electrical parameters remain identical. ERJ-2RKF1872X carries Automotive AEC-Q200 qualification, which the original part does not specify. This upgrade substitute is suitable when additional thermal headroom is required or automotive qualification is mandated.

Q: Are the automotive-qualified alternatives (AC0402FR-0718K7L, CRCW040218K7FKED, RMCF0402FT18K7) compatible with the original design?

A: Yes. All three automotive-qualified alternatives maintain the original 0.063W power rating and identical electrical specifications. They are suitable for direct substitution in designs where Automotive AEC-Q200 qualification is required or preferred. The original RC1005F1872CS does not specify automotive qualification, so these alternatives represent qualified options for automotive applications.

Q: Does package footprint differ among these substitutes?

A: No. All substitute parts use the 0402 (1005 Metric) package with identical dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm). Maximum seated height is 0.016" (0.40mm) for all parts except AC0402FR-0718K7L, which specifies 0.015" (0.37mm). This minor height variation does not affect PCB layout compatibility.

Q: What is the significance of MSL Level 1 rating?

A: MSL Level 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts, including the original and all substitutes, carry this rating, ensuring consistent moisture sensitivity management across all options.

Q: Can these parts be used interchangeably in high-reliability applications?

A: All substitute parts maintain ROHS3 compliance and MSL Level 1 rating consistent with the original. For applications requiring Automotive AEC-Q200 qualification, the automotive-qualified alternatives (AC0402FR-0718K7L, CRCW040218K7FKED, RMCF0402FT18K7) and the upgrade substitute ERJ-2RKF1872X are appropriate selections. The direct equivalent RC0402FR-0718L is suitable for non-automotive applications with identical specifications to the original.
