Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERJ-S1TF10R2U is determined by strict equivalence in the following parameters:

• Resistance value: 10.2 Ohms
• Tolerance: ±1%
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Automotive Rating: AEC-Q200

The substitute part CRCW251210R2FKEGHP meets all these criteria. While the substitute offers a higher power rating (1.5W versus 1W), this represents an upgrade in thermal capability and does not compromise compatibility. Both parts maintain identical resistance, tolerance, package dimensions, and automotive qualification standards.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF10R2U and CRCW251210R2FKEGHP are active production parts with AEC-Q200 automotive qualification. The substitute part CRCW251210R2FKEGHP provides equivalent electrical performance with a 50% increase in power dissipation capability (1.5W versus 1W). Physical dimensions are within acceptable tolerance for 2512 package specifications, with both parts maintaining identical height and compatible footprints. Selection between these parts should be based on availability, supply chain requirements, and thermal design margins in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can CRCW251210R2FKEGHP be used as a direct replacement for ERJ-S1TF10R2U?

A: Yes. Both parts share identical resistance (10.2 Ohms), tolerance (±1%), package (2512), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The substitute offers higher power rating (1.5W), which does not create compatibility issues.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within 2512 package tolerance. ERJ-S1TF10R2U measures 0.252" L x 0.126" W (6.40mm x 3.20mm), while CRCW251210R2FKEGHP measures 0.248" L x 0.124" W (6.30mm x 3.15mm). Both maintain 0.028" (0.70mm) maximum seated height. These differences are within standard PCB footprint design tolerances for the 2512 package.

Q: What is the significance of the higher power rating on the substitute part?

A: The CRCW251210R2FKEGHP 1.5W rating provides additional thermal margin compared to the 1W ERJ-S1TF10R2U. This allows the substitute to dissipate more power without exceeding temperature limits, making it suitable for applications with higher current demands or elevated ambient temperatures.

Q: Are both parts automotive qualified?

A: Yes. Both the ERJ-S1TF10R2U and CRCW251210R2FKEGHP carry AEC-Q200 automotive qualification, confirming compliance with automotive reliability and quality standards.

Q: What packaging formats are available for these parts?

A: The ERJ-S1TF10R2U is supplied in Tape & Reel (TR) format. The CRCW251210R2FKEGHP is available in Cut Tape (CT) & Digi-Reel® format. Both packaging options are suitable for automated assembly processes.
