Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F4872CS are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters (Must Match Exactly):

• Resistance value: 48.7 kOhms
• Tolerance: ±1%
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100 ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Terminations: 2
• RoHS3 Compliance
• MSL 1 (Unlimited)

Allowable Variations:

• Power rating: 0.063W (1/16W) or higher (1/10W upgrade acceptable)
• Features: Moisture resistant or automotive AEC-Q200 qualification (additional features do not disqualify substitution)
• Seated height: Minor variations within manufacturing tolerance

All identified substitutes maintain identical electrical performance and mechanical compatibility with the original RC1005F4872CS specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications): CR0402-FX-4872GLF (Bourns Inc.) and RC0402FR-0748K7L (YAGEO) are direct equivalents with matching electrical and mechanical parameters. Both maintain active product status and ROHS3 compliance. Selection between these and the original RC1005F4872CS depends on procurement availability and supply chain requirements.

Upgrade Option (Enhanced Power Rating): ERJ-2RKF4872X (Panasonic Electronic Components) provides a 1/10W (0.1W) power rating compared to the standard 1/16W (0.063W), offering improved thermal margin in power-dissipation-sensitive applications. This part includes automotive AEC-Q200 qualification and maintains all other electrical parameters. Upgrade substitution is applicable when higher power dissipation capability is beneficial.

Automotive-Qualified Alternatives: AC0402FR-0748K7L (YAGEO), CRCW040248K7FKED (Vishay Dale), and RMCF0402FT48K7 (Stackpole Electronics Inc) incorporate automotive AEC-Q200 qualification in addition to standard specifications. These parts are suitable for applications requiring automotive-grade component certification while maintaining identical electrical performance and 0402 package compatibility.

All substitute parts are active products with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and environmental regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-4872GLF replace RC1005F4872CS in all applications? A: Yes. CR0402-FX-4872GLF is a direct equivalent with identical resistance, tolerance, power rating, package, temperature coefficient, and operating temperature range. Both parts are ROHS3 compliant with MSL 1 rating. No design changes are required.

Q: What is the difference between the standard RC1005F4872CS and the ERJ-2RKF4872X? A: The primary difference is power rating: RC1005F4872CS is rated at 0.063W (1/16W), while ERJ-2RKF4872X is rated at 0.1W (1/10W). All other electrical parameters are identical. ERJ-2RKF4872X includes automotive AEC-Q200 qualification. The upgrade is suitable for applications requiring higher power dissipation capability.

Q: Are automotive AEC-Q200 qualified parts (AC0402FR-0748K7L, CRCW040248K7FKED, RMCF0402FT48K7) compatible with non-automotive applications? A: Yes. Automotive AEC-Q200 qualification represents an additional quality and reliability standard. These parts meet or exceed all specifications of the standard RC1005F4872CS and are fully compatible with non-automotive applications. Automotive qualification does not restrict use in other applications.

Q: Does the moisture resistant feature of RC1005F4872CS affect substitution compatibility? A: No. Moisture resistance is a feature that enhances reliability in humid environments. Substitute parts without explicit moisture resistant designation (CR0402-FX-4872GLF) are still electrically and mechanically compatible. Parts with moisture resistant features (RC0402FR-0748L, AC0402FR-0748K7L) provide equivalent or enhanced performance. Feature presence does not disqualify substitution.

Q: Can I use AC0402FR-0748K7L as a direct replacement for RC1005F4872CS? A: Yes. AC0402FR-0748K7L maintains identical electrical specifications (48.7 kOhms ±1%, 0.063W, ±100 ppm/°C, -55°C to 155°C) and 0402 package format. It includes both moisture resistant and automotive AEC-Q200 features, providing equivalent or enhanced reliability. Direct substitution is valid.

Q: What is the significance of MSL 1 (Unlimited) rating for all parts? A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts share this rating, ensuring consistent handling and storage procedures across substitutes. No special moisture control measures are required for any of these parts.

Q: Are there any height differences between substitute parts that affect PCB assembly? A: Seated heights are nominally 0.016" (0.40mm) for most parts, with AC0402FR-0748K7L at 0.015" (0.37mm). These variations fall within standard 0402 package tolerance and do not affect PCB assembly compatibility or solder reflow processes.

Q: Which substitute part offers the best availability? A: RC0402FR-0748K7L (YAGEO) shows the highest inventory level at 159,087 pieces. ERJ-2RKF4872X (Panasonic) follows with 145,717 pieces. Both parts maintain active production status and are suitable for high-volume procurement requirements.
