RC5025F1152CS Equivalent & Substitute Parts

Part Overview

The RC5025F1152CS is a 11.5 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 currently in active production status with 830 pieces available in inventory.

The RC5025F1152CS is designed for applications requiring precision resistive elements with moisture resistance and stable performance across industrial temperature ranges. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and package standardization. Substitutes become necessary when the primary part experiences supply constraints, when design requirements shift toward automotive-qualified alternatives, or when higher power ratings are required within the same package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F1152CS is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Resistance Value: 11.5 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power ratings within the same package
• Moisture Sensitivity Level: MSL 1 (Unlimited) is maintained across all substitutes
• RoHS Status: ROHS3 Compliant maintained
• Product Status: Active or Not For New Designs

The ERJ-12SF1152U from Panasonic Electronic Components qualifies as a direct substitute. This part maintains identical resistance, tolerance, package dimensions, composition, and temperature specifications. The primary difference is an increased power rating of 0.75W (3/4W) compared to the 0.667W rating of the RC5025F1152CS. This higher power rating does not create incompatibility; it provides additional thermal margin in the same physical footprint. The ERJ-12SF1152U carries automotive AEC-Q200 qualification, which represents an enhanced reliability standard applicable to automotive environments.

Parameter Comparison

Engineering Selection Recommendations

RC5025F1152CS Selection Criteria: The RC5025F1152CS is the primary choice for new designs requiring an 11.5 kOhms ±1% thick film resistor in 2010 package format. This part maintains active production status, ensuring long-term supply availability and consistent manufacturing quality. The component is ROHS3 compliant and carries unlimited moisture sensitivity rating, suitable for standard industrial and consumer applications operating within -55°C to 155°C temperature range.

ERJ-12SF1152U Selection Criteria: The ERJ-12SF1152U serves as a functional equivalent when supply of the RC5025F1152CS is constrained or when design requirements include automotive environmental qualification. The higher 0.75W power rating provides additional thermal headroom within the identical 2010 package footprint. The AEC-Q200 automotive qualification indicates enhanced reliability testing and process controls suitable for automotive-grade applications. However, the ERJ-12SF1152U carries "Not For New Designs" status, indicating Panasonic has transitioned this part to mature/legacy phase. Selection of this substitute should be limited to replacement scenarios or designs where automotive qualification is a specific requirement.

Height Consideration: The seated height difference of 0.002" (0.04mm) between parts is negligible for standard PCB assembly processes and does not create mechanical incompatibility in typical applications.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-12SF1152U directly replace the RC5025F1152CS in existing designs?

A: Yes. Both parts share identical resistance value (11.5 kOhms), tolerance (±1%), package (2010/5025 Metric), composition (thick film), and operating temperature range (-55°C to 155°C). The ERJ-12SF1152U has a higher power rating (0.75W vs. 0.667W), which does not create incompatibility. The 0.002" height difference is within standard PCB assembly tolerances.

Q: What is the significance of the "Not For New Designs" status on the ERJ-12SF1152U?

A: This designation indicates that Panasonic has classified the ERJ-12SF1152U as a mature product no longer recommended for incorporation into new circuit designs. The part remains available for replacement and repair of existing equipment. For new designs, the RC5025F1152CS (active status) is the preferred selection.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. The ERJ-12SF1152U includes AEC-Q200 automotive qualification, which the RC5025F1152CS does not specify. AEC-Q200 qualification indicates enhanced reliability testing suitable for automotive environments.

Q: Does the higher power rating of the ERJ-12SF1152U affect circuit performance?

A: No. A higher power rating indicates greater thermal capacity within the same package. This does not alter electrical performance (resistance, tolerance, temperature coefficient) and provides additional safety margin for thermal dissipation in the application.

Q: What packaging formats are available for these parts?

A: The RC5025F1152CS is available in standard packaging. The ERJ-12SF1152U is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.

Q: Can these parts be used interchangeably in automotive applications?

A: The ERJ-12SF1152U carries explicit AEC-Q200 automotive qualification. The RC5025F1152CS does not specify automotive qualification. For automotive applications requiring AEC-Q200 compliance, the ERJ-12SF1152U is the appropriate selection. For non-automotive applications, both parts are functionally equivalent.
