Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSRN2010JT50L0 is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 50 mOhms
• Power rating: 1W
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Features: Current Sense
• Temperature Coefficient: ±250ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Tolerance: The main part specifies ±5%. Substitute parts with equal or tighter tolerance (±1%) are functionally compatible and provide enhanced precision for current sense applications.

The CSRN2010FK50L0 meets all mandatory parameters and offers improved tolerance specification, making it a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2010JT50L0 and CSRN2010FK50L0 are Active status products from Stackpole Electronics Inc and maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. The primary distinction is tolerance specification. The CSRN2010FK50L0 provides ±1% tolerance compared to the ±5% tolerance of the main part, while maintaining all other electrical and mechanical parameters. Selection between these parts depends on circuit precision requirements and tolerance budget for current sense applications.

Frequently Asked Questions (FAQ)

Q: Can CSRN2010FK50L0 be used as a direct replacement for CSRN2010JT50L0?

A: Yes. Both parts share identical resistance value (50 mOhms), power rating (1W), package (2010 / 5025 Metric), composition (Thick Film), temperature coefficient (±250ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance status (ROHS3, REACH Unaffected). The CSRN2010FK50L0 features tighter tolerance (±1% vs ±5%), which is compatible with applications designed for the main part.

Q: What is the significance of tolerance difference between these parts?

A: Tolerance defines the acceptable resistance deviation from the nominal 50 mOhm value. The CSRN2010JT50L0 allows ±5% deviation (47.5 to 52.5 mOhms), while CSRN2010FK50L0 allows ±1% deviation (49.5 to 50.5 mOhms). Tighter tolerance provides improved accuracy for current measurement circuits.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 2010 (5025 Metric) with dimensions of 0.197" L x 0.097" W (5.00mm x 2.45mm) and maximum seated height of 0.030" (0.75mm). They are mechanically interchangeable on PCBs designed for either part.

Q: Do these parts have the same moisture sensitivity?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both CSRN2010JT50L0 and CSRN2010FK50L0 are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
