Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRF1206JT16L0 is determined by the following critical parameters:

• Resistance Value: Must be 16 mOhms (exact match required)
• Package / Case: Must be 1206 (3216 Metric) for PCB footprint compatibility
• Power Rating: Must be 1W or greater
• Composition: Metal foil construction for current sense applications
• Automotive Compliance: AEC-Q200 qualification required
• Operating Temperature Range: Must support -55°C to 170°C minimum
• Moisture Sensitivity: MSL 1 or better
• RoHS Compliance: ROHS3 Compliant

The CSRF1206FT16L0 qualifies as a direct substitute by meeting all mandatory parameters. The primary distinction is an improved tolerance specification (±1% versus ±5%), which represents an upgrade in precision without compromising any electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRF1206JT16L0 and CSRF1206FT16L0 are active production parts from Stackpole Electronics Inc with full AEC-Q200 automotive qualification. Both parts maintain identical electrical performance in terms of resistance value, power rating, temperature coefficient, and operating temperature range. Both achieve ROHS3 compliance and MSL 1 moisture sensitivity rating.

The CSRF1206FT16L0 provides improved tolerance specification at ±1% compared to the ±5% tolerance of the CSRF1206JT16L0. This enhanced precision may be beneficial in applications requiring tighter current measurement accuracy. The selection between these parts should be based on the specific tolerance requirements of the circuit design and application performance criteria.

Frequently Asked Questions (FAQ)

Q: Can CSRF1206FT16L0 be used as a direct replacement for CSRF1206JT16L0?

A: Yes. Both parts share identical resistance value (16 mOhms), package (1206), power rating (1W), composition (metal foil), and automotive qualification (AEC-Q200). The CSRF1206FT16L0 features improved tolerance (±1% versus ±5%), making it a compatible upgrade.

Q: Are there any PCB layout or footprint differences between these parts?

A: No. Both parts use the 1206 (3216 Metric) package with identical dimensions: 0.122" L × 0.061" W (3.10mm × 1.55mm) and maximum seated height of 0.033" (0.85mm). PCB footprints are interchangeable.

Q: What is the significance of the tolerance difference?

A: Tolerance defines the acceptable deviation from the nominal 16 mOhm resistance value. The CSRF1206JT16L0 allows ±5% deviation (15.2 to 16.8 mOhms), while CSRF1206FT16L0 allows ±1% deviation (15.84 to 16.16 mOhms). Tighter tolerance improves current measurement precision in sensing applications.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both parts carry AEC-Q200 qualification, confirming suitability for automotive applications across the -55°C to 170°C operating temperature range.

Q: Are there inventory or lead time considerations?

A: Both parts are actively produced. Current inventory shows 986 units of CSRF1206JT16L0 and 941 units of CSRF1206FT16L0 available as new original stock.
