RC5025F9092CS Equivalent & Substitute Parts

Part Overview

The RC5025F9092CS is a 90.9 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status and is moisture resistant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the primary component becomes unavailable, when design requirements shift toward automotive-qualified alternatives, or when higher power ratings are required within the same package footprint and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC5025F9092CS is based on strict electrical and mechanical parameter matching:

Mandatory Matching Parameters:

• Resistance value: 90.9 kOhms (exact match required)
• Tolerance: ±1% (substitute tolerance must not exceed this value)
• Package: 2010 (5025 Metric) form factor (physical compatibility)
• Composition: Thick film construction (electrical performance characteristics)
• Temperature coefficient: ±100ppm/°C (stability and accuracy)
• Operating temperature range: -55°C ~ 155°C (environmental suitability)

Allowable Variation:

• Power rating: Substitute must equal or exceed 0.667W minimum
• RoHS compliance: Must maintain ROHS3 Compliant status
• Moisture sensitivity: MSL 1 is acceptable; higher MSL values are not substitutable

The ERJ-12SF9092U qualifies as a direct substitute because it matches all mandatory parameters while providing a higher power rating (0.75W vs. 0.667W), maintains identical tolerance and temperature coefficient specifications, and preserves all regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC5025F9092CS): Select the RC5025F9092CS for new designs requiring an active, production-supported 90.9 kOhms ±1% resistor in 2010 package format. This component offers standard thick film performance with moisture resistance and full RoHS3 compliance. Active product status ensures long-term availability and supply chain stability.

Substitute Selection (ERJ-12SF9092U): The ERJ-12SF9092U is substitutable when the RC5025F9092CS becomes unavailable. This Panasonic component maintains identical electrical specifications (90.9 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C) and package dimensions. The higher power rating (0.75W vs. 0.667W) provides additional thermal margin without affecting circuit performance. The AEC-Q200 automotive qualification adds value for applications requiring automotive-grade components.

Substitution Constraints: The ERJ-12SF9092U carries "Not For New Designs" status, restricting its use to replacement and legacy support applications only. The maximum seated height increases from 0.66mm to 0.70mm; verify clearance in space-constrained PCB layouts before substitution. Packaging differs (Tape & Reel for substitute vs. standard packaging for main part); confirm reel specifications match assembly equipment requirements.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-12SF9092U replace the RC5025F9092CS in existing designs?

A: Yes. The ERJ-12SF9092U is electrically and mechanically compatible. Both components share identical resistance value (90.9 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and 2010 package footprint. The substitute's higher power rating (0.75W vs. 0.667W) does not create incompatibility. Verify PCB layout clearance for the 0.04mm height difference (0.70mm vs. 0.66mm maximum seated height).

Q: Why is the ERJ-12SF9092U marked "Not For New Designs"?

A: Product status reflects manufacturer lifecycle decisions. The "Not For New Designs" designation indicates Panasonic has transitioned this part to legacy support mode. New designs should prioritize the RC5025F9092CS (Active status) or evaluate alternative suppliers. The ERJ-12SF9092U remains suitable for replacement, repair, and sustaining engineering applications.

Q: Are there differences in packaging between these two parts?

A: Yes. The RC5025F9092CS uses standard packaging, while the ERJ-12SF9092U is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated assembly equipment. Confirm your pick-and-place system supports the reel specifications before ordering the substitute.

Q: Does the AEC-Q200 qualification on the ERJ-12SF9092U affect substitution?

A: No. AEC-Q200 is an automotive qualification that the ERJ-12SF9092U possesses but the RC5025F9092CS does not. This qualification adds capability without creating incompatibility. If your application requires automotive-grade components, the ERJ-12SF9092U provides this additional assurance.

Q: What is the moisture sensitivity level (MSL) for both parts?

A: Both components are rated MSL 1 (Unlimited), meaning they have unlimited shelf life and require no special moisture control during storage or handling. This simplifies inventory management and reduces handling costs compared to higher MSL ratings.

Q: Can I use these resistors interchangeably in high-temperature applications?

A: Yes. Both components operate across the identical temperature range (-55°C ~ 155°C) with matching temperature coefficients (±100ppm/°C). Thermal performance is equivalent, and substitution does not affect temperature stability or accuracy in high-temperature environments.

Q: What compliance certifications apply to both parts?

A: Both the RC5025F9092CS and ERJ-12SF9092U are ROHS3 Compliant and REACH Unaffected. Both carry ECCN classification EAR99 and HTSUS code 8533.21.0030. Regulatory compliance is maintained across substitution.
