RC5025F3163CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F3163CS is a 316 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) in a 2010 (5025 Metric) package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers meeting equivalent electrical and mechanical specifications. The ERJ-12SF3163U from Panasonic Electronic Components serves as a documented equivalent, though with modified power rating and compliance status requiring engineering evaluation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F3163CS is determined by strict adherence to the following parameters:

Mandatory Match Parameters:

• Resistance value: 316 kOhms
• Tolerance: ±1%
• Package designation: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Number of terminations: 2

Allowable Variance Parameters:

• Power rating: Substitute must be equal to or greater than 0.667W
• Operating temperature range: Substitute must support -55°C ~ 155°C minimum
• Moisture sensitivity level: Substitute must be MSL 1 or equivalent

The ERJ-12SF3163U qualifies as a substitute based on matching all mandatory parameters and exceeding the power rating (0.75W vs. 0.667W). However, compliance status differences require explicit engineering consideration during selection.

Parameter Comparison

Engineering Selection Recommendations

RC5025F3163CS Selection Criteria:

• Primary choice for new designs requiring RoHS3 compliance
• Active product status ensures long-term availability and supply chain stability
• Suitable for applications without automotive qualification requirements
• Recommended for designs with strict environmental compliance mandates

ERJ-12SF3163U Selection Criteria:

• Applicable only to legacy designs or existing production lines already qualified to this component
• Product status "Not For New Designs" restricts use to maintenance, repair, or replacement scenarios
• RoHS non-compliance requires explicit design review and customer approval
• AEC-Q200 automotive qualification provides additional reliability data for automotive applications, though primary part lacks this designation
• Higher power rating (0.75W vs. 0.667W) provides thermal margin in power-dissipation-critical circuits
• Marginal height increase (0.028" vs. 0.026") requires PCB layout verification for space-constrained applications

Compliance Considerations: The RC5025F3163CS maintains RoHS3 compliance and Active status, making it the preferred selection for new product development. The ERJ-12SF3163U's RoHS non-compliance and "Not For New Designs" status limit its application to retrofit or legacy support scenarios where the original specification has been established.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF3163U be used as a direct replacement for RC5025F3163CS in new designs?

A: No. The ERJ-12SF3163U carries "Not For New Designs" product status and RoHS non-compliance. New designs must use RC5025F3163CS or identify alternative parts meeting current compliance requirements.

Q: What is the significance of the power rating difference (0.667W vs. 0.75W)?

A: The ERJ-12SF3163U's higher power rating (0.75W) exceeds the RC5025F3163CS requirement (0.667W), providing additional thermal headroom. This does not create incompatibility; the substitute can safely handle the same power dissipation as the main part with lower operating temperature rise.

Q: Does the 0.002" height difference (0.026" vs. 0.028") affect PCB assembly?

A: The height difference is minimal (0.66mm vs. 0.70mm). Verify PCB layout clearances for space-constrained applications, particularly in stacked component configurations or under shielding. Standard PCB design tolerances typically accommodate this variance.

Q: Why does ERJ-12SF3163U have AEC-Q200 rating while RC5025F3163CS does not?

A: AEC-Q200 is an automotive qualification standard. The ERJ-12SF3163U includes this certification; the RC5025F3163CS does not. For automotive applications, verify whether AEC-Q200 qualification is a design requirement before selecting either component.

Q: Are there other substitutes beyond ERJ-12SF3163U?

A: The ERJ-12SF3163U documentation references additional substitutes (ERJ-S1DF3163U, RMCF2010FT316K, AC2010FK-07316KL, CRCW2010316KFKTF, CRCW2010316KFKEF). Each requires individual parameter verification against the RC5025F3163CS specification before qualification.

Q: What packaging format is RC5025F3163CS supplied in?

A: RC5025F3163CS is supplied in standard packaging (format not specified in provided data). ERJ-12SF3163U is supplied in Tape & Reel (TR) format. Verify packaging compatibility with assembly equipment and procurement requirements.

Q: Can RC5025F3163CS be used in place of ERJ-12SF3163U in existing production?

A: Yes, provided the original design specification permits RoHS3 compliance and does not require AEC-Q200 automotive qualification. The RC5025F3163CS meets all electrical and mechanical parameters of the ERJ-12SF3163U with enhanced compliance status.
