Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206JT12L0 is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Resistance value: 12 mOhms
• Power rating: 0.5W
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance status
• Moisture sensitivity level: 1

Allowable Variation:

• Tolerance: May be equal or tighter (±5% or better)

The CSR1206FK12L0 qualifies as a direct substitute because it maintains all critical parameters while offering improved tolerance specification (±1% versus ±5%), making it suitable for applications requiring higher precision without any electrical or mechanical compromise.

Parameter Comparison

Engineering Selection Recommendations

Both CSR1206JT12L0 and CSR1206FK12L0 maintain Active product status with identical compliance certifications (RoHS3, REACH Unaffected, EAR99 classification). Selection between these parts depends on application tolerance requirements:

The CSR1206JT12L0 is appropriate for applications where ±5% tolerance meets circuit specifications and cost optimization is prioritized.

The CSR1206FK12L0 is appropriate for precision current sensing applications requiring tighter tolerance control (±1%), offering improved measurement accuracy without any electrical or mechanical trade-offs. Both parts are suitable for direct PCB assembly using standard surface mount equipment and processes.

Frequently Asked Questions (FAQ)

Q: Can CSR1206FK12L0 replace CSR1206JT12L0 in existing designs?

A: Yes. The CSR1206FK12L0 is a direct mechanical and electrical substitute. It occupies the same 1206 package footprint and maintains identical power rating, temperature range, and thermal characteristics. The tighter ±1% tolerance provides equal or superior performance in all applications.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. CSR1206JT12L0 carries ±5% tolerance, while CSR1206FK12L0 carries ±1% tolerance. All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -55°C to 155°C with matching ±100ppm/°C temperature coefficient, making them suitable for the same thermal environments.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts share identical moisture sensitivity level (MSL 1 - Unlimited), eliminating any difference in storage, handling, or shelf-life management requirements.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes. Both parts are supplied in Tape & Reel packaging and use the identical 1206 package format, allowing seamless integration into existing pick-and-place assembly processes without equipment reconfiguration.
