Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CSRF1206JT5L00 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 5 mOhms
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 170°C
• Automotive qualification: AEC-Q200

Mechanical Parameters (Must Match):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Moisture sensitivity level: MSL 1

Allowable Variations:

• Tolerance: May be improved from ±5% to ±1%
• Composition: Metal foil or metal film acceptable
• Manufacturer: Different qualified suppliers permitted

Two substitute parts meet these criteria: CSRF1206FT5L00 (Stackpole Electronics Inc, upgraded tolerance) and PE1206FRF470R005L (YAGEO, upgraded tolerance with metal film composition).

Parameter Comparison

Engineering Selection Recommendations

CSRF1206FT5L00 is the primary substitute when tolerance improvement is acceptable. This part maintains identical composition (metal foil), manufacturer continuity with Stackpole Electronics Inc, and all electrical and mechanical specifications. The ±1% tolerance provides superior accuracy compared to the ±5% specification of the main part. Significantly higher inventory availability (438,268 pieces) supports production continuity.

PE1206FRF470R005L is an alternative substitute when sourcing from multiple manufacturers is required. This YAGEO part meets all electrical and mechanical requirements with ±1% tolerance. The metal film composition differs from the metal foil construction of the primary part but maintains equivalent performance within the specified operating parameters. Inventory availability is adequate at 7,700 pieces.

Both substitutes carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating, ensuring compatibility with automotive and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can CSRF1206FT5L00 be used as a direct replacement for CSRF1206JT5L00?

A: Yes. Both parts share identical resistance (5 mOhms), power rating (1W), package (1206), temperature coefficient (±100ppm/°C), operating range (-55°C to 170°C), and AEC-Q200 qualification. The CSRF1206FT5L00 provides improved tolerance (±1% versus ±5%), making it a direct upgrade.

Q: What is the difference between metal foil and metal film composition in these resistors?

A: Both compositions meet the specified electrical parameters for this application. Metal foil construction (CSRF1206JT5L00 and CSRF1206FT5L00) and metal film construction (PE1206FRF470R005L) deliver equivalent temperature coefficient (±100ppm/°C) and operating range performance. Selection depends on application-specific requirements not specified in the base parameters.

Q: Are the physical dimensions identical across all three parts?

A: The package designation is 1206 (3216 Metric) for all parts. CSRF1206JT5L00 and CSRF1206FT5L00 have identical dimensions (0.122" L x 0.061" W, height 0.033" max). PE1206FRF470R005L dimensions are 0.126" L x 0.063" W with height 0.035" max. These minor dimensional variations remain within 1206 package tolerance and do not affect PCB footprint compatibility.

Q: Can PE1206FRF470R005L be substituted in automotive applications?

A: Yes. PE1206FRF470R005L carries AEC-Q200 qualification, ROHS3 compliance, and MSL 1 rating, meeting automotive reliability requirements equivalent to the main part.

Q: What inventory considerations apply to these substitutes?

A: CSRF1206FT5L00 offers the highest inventory availability (438,268 pieces), supporting large-volume production. PE1206FRF470R005L provides adequate stock (7,700 pieces) for standard production runs. The main part CSRF1206JT5L00 has lower availability (927 pieces), making substitutes preferable for sustained sourcing.
