Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of electrical and mechanical parameters. The following criteria establish valid equivalency:

Primary Matching Criteria:

• Resistance value: 130 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• Temperature coefficient: ±150ppm/°C or better (maximum drift tolerance)

Secondary Compatibility Factors:

• Power rating: Equal to or greater than 0.25W
• RoHS compliance: ROHS3 or equivalent
• Moisture sensitivity: MSL 1 (Unlimited)
• Termination count: 2 (standard for chip resistors)

Substitute parts are grouped based on power rating variations and application-specific feature enhancements. Parts exceeding the minimum power specification remain functionally compatible within the same thermal and electrical operating envelope.

Parameter Comparison

Engineering Selection Recommendations

RUT2012FR130CS (Samsung Electro-Mechanics)

This part is the primary specification component with Active product status. Selection is appropriate for standard current sensing applications where moisture resistance is required and automotive qualification is not mandated. The 0.25W power rating provides adequate thermal capacity for typical low-current measurement circuits.

ERJ-6DSFR13V (Panasonic Electronic Components)

This substitute offers increased power dissipation capability at 0.5W (1/2W), providing thermal margin for applications with higher ambient temperatures or sustained current levels. AEC-Q200 automotive qualification extends application scope to automotive and industrial environments. The temperature coefficient specification of 0/+150ppm/°C indicates asymmetrical drift characteristics. Height dimension of 0.028" (0.70mm) is marginally higher than the main part; verify PCB clearance in space-constrained layouts.

ERJ-U6SFR13V (Panasonic Electronic Components)

This substitute maintains identical power rating (0.25W) and temperature coefficient (±150ppm/°C) to the main part, providing direct functional equivalency. Anti-sulfur feature provides enhanced environmental protection in corrosive atmospheres. AEC-Q200 automotive qualification enables use in automotive and harsh industrial applications. Height dimension of 0.026" (0.65mm) is within 0.002" of the main part, ensuring compatibility with standard PCB assembly processes.

All three parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical core specifications (130 mOhms ±1%, 0805 package, thick film composition, -55°C to 155°C operating range).

Frequently Asked Questions (FAQ)

Q: Can ERJ-6DSFR13V (0.5W) be used in place of RUT2012FR130CS (0.25W)?

A: Yes. The higher power rating of ERJ-6DSFR13V provides equal or greater thermal capability. The component will operate within specification in any circuit designed for the 0.25W part. Verify PCB clearance for the 0.028" (0.70mm) maximum seated height, which is 0.004" taller than the main part.

Q: What is the difference between ERJ-U6SFR13V and RUT2012FR130CS?

A: Both parts share identical electrical specifications: 130 mOhms ±1%, 0.25W power rating, ±150ppm/°C temperature coefficient, and 0805 package. ERJ-U6SFR13V includes anti-sulfur feature and AEC-Q200 automotive qualification. Physical height differs by 0.002" (0.65mm vs 0.61mm), which is negligible for standard assembly.

Q: Are all three parts suitable for automotive applications?

A: RUT2012FR130CS does not specify automotive qualification. ERJ-6DSFR13V and ERJ-U6SFR13V both carry AEC-Q200 automotive qualification, making them suitable for automotive and harsh industrial environments.

Q: Does package footprint differ between these parts?

A: All three parts use 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Seated height varies slightly: RUT2012FR130CS at 0.024" (0.61mm), ERJ-U6SFR13V at 0.026" (0.65mm), and ERJ-6DSFR13V at 0.028" (0.70mm). These variations are within standard PCB assembly tolerances.

Q: What is the significance of temperature coefficient differences?

A: RUT2012FR130CS and ERJ-U6SFR13V specify ±150ppm/°C (symmetrical drift). ERJ-6DSFR13V specifies 0/+150ppm/°C (asymmetrical, positive drift only). For precision current sensing circuits, symmetrical temperature coefficient provides more predictable resistance behavior across the full operating temperature range.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design accommodates the maximum seated height of 0.028" (0.70mm) and the application does not require specific automotive qualification. Electrical performance is equivalent across all three parts for the specified 130 mOhms ±1% resistance value and 0.25W minimum power rating.
