RC5025F46R4CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F46R4CS is a 46.4 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format. This component is rated for 0.667W (2/3W) continuous power dissipation with moisture-resistant construction and operates across the -55°C to 155°C temperature range. The part maintains Active product status and carries ROHS3 compliance with MSL Level 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package dimensions, termination count) while accounting for variations in power rating, automotive qualification, and product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F46R4CS is determined by the following mandatory parameters:

Electrical Compatibility Requirements:

• Resistance value: 46.4 Ohms (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 Compatibility Requirements:

• Package / Case: 2010 (5025 Metric) (exact match required)
• Size / Dimension: 0.197" L x 0.098" W (5.00mm x 2.50mm) (exact match required)
• Number of Terminations: 2 (exact match required)

Acceptable Variation Parameters:

• Power Rating: Substitute parts rated at 0.75W (3/4W) or higher are acceptable for applications requiring the RC5025F46R4CS at 0.667W (2/3W), provided circuit design accommodates the physical height difference
• Features: Automotive AEC-Q200 qualification is an enhancement and does not restrict substitution
• Composition: Thick Film (exact match required)

All identified substitute parts meet these criteria and maintain ROHS3 compliance, MSL Level 1 rating, and identical electrical performance within the specified tolerance band.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW201046R4FKEF (Vishay Dale) and RMCF2010FT46R4 (Stackpole Electronics Inc) are the preferred substitute options. Both parts maintain Active product status, carry AEC-Q200 automotive qualification, and provide 0.75W power rating with identical electrical specifications. These components are suitable for direct replacement in new designs and production applications.

Secondary Substitute (Not For New Designs):

ERJ-12SF46R4U (Panasonic Electronic Components) meets all electrical and mechanical compatibility requirements and carries AEC-Q200 qualification. However, this part is designated "Not For New Designs" and should be used only for legacy system maintenance, repair, or where existing design documentation specifies this component.

Height Consideration:

All substitute parts exhibit a maximum seated height of 0.028" (0.70mm) compared to the RC5025F46R4CS at 0.026" (0.66mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not restrict substitution for standard applications. Applications with critical height constraints should confirm compatibility with design specifications.

Power Rating Upgrade:

The substitute parts rated at 0.75W (3/4W) provide enhanced thermal margin compared to the 0.667W (2/3W) RC5025F46R4CS. This upgrade is unconditionally acceptable for applications operating at or below the original power specification.

Frequently Asked Questions (FAQ)

Q: Can CRCW201046R4FKEF replace RC5025F46R4CS in existing designs?

A: Yes. CRCW201046R4FKEF provides identical electrical performance (46.4 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C) and mechanical compatibility (2010 package, 5.00mm x 2.50mm). The 0.75W power rating exceeds the original 0.667W specification, providing additional thermal margin. The 0.002" height difference is within standard PCB assembly tolerances.

Q: What is the difference between the RC5025F46R4CS and ERJ-12SF46R4U?

A: Both parts are electrically and mechanically identical with 46.4 Ohms ±1% resistance, ±100ppm/°C temperature coefficient, and 2010 package format. The primary difference is product lifecycle status: RC5025F46R4CS is Active, while ERJ-12SF46R4U is designated Not For New Designs. ERJ-12SF46R4U is suitable for legacy system support only.

Q: Are all substitute parts AEC-Q200 qualified?

A: CRCW201046R4FKEF and RMCF2010FT46R4 carry AEC-Q200 automotive qualification. ERJ-12SF46R4U also carries AEC-Q200 qualification. The original RC5025F46R4CS is specified as moisture-resistant but does not carry explicit AEC-Q200 designation. For automotive applications requiring AEC-Q200 compliance, substitute parts provide enhanced qualification.

Q: Does the 0.75W rating of substitute parts affect circuit performance?

A: No. The 0.75W rating of substitute parts is a higher power capability than the original 0.667W specification. If the original design operates at or below 0.667W, the substitute part will operate within its rated limits with improved thermal performance. No circuit redesign is required.

Q: Can I use RMCF2010FT46R4 in place of RC5025F46R4CS for new production?

A: Yes. RMCF2010FT46R4 maintains Active product status, meets all electrical specifications (46.4 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C), and provides identical mechanical compatibility (2010 package). This part is suitable for new design implementation and production applications.

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

A: MSL Level 1 (Unlimited) indicates unlimited shelf life without moisture bake-out requirements. All listed parts, including the RC5025F46R4CS and all substitutes, carry MSL Level 1 rating, ensuring consistent handling and storage procedures across all options.

Q: Are all parts ROHS3 compliant?

A: Yes. The RC5025F46R4CS and all identified substitute parts (CRCW201046R4FKEF, ERJ-12SF46R4U, RMCF2010FT46R4) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
