Substitute Part Grouping Explanation

Substitute parts for the CSL0902BT1C are identified based on strict electrical and mechanical parameter matching within the automotive-grade blue LED indicator category. The substitution logic is based on the following critical parameters that must remain constant:

Electrical Parameters:

• Dominant wavelength: 470nm (blue spectrum)
• Forward voltage (Vf): 3.3V
• Test current: 20mA
• Millicandela rating: 360mcd

Mechanical Parameters:

• Package format: 0603 (1608 Metric)
• Mounting type: Surface Mount
• Lens configuration: Colorless, clear, rectangle with domed top
• Physical dimensions: 1.60mm L x 0.80mm W, 1.34mm max height
• Lens size: 1.14mm x 0.80mm

Compliance & Grade:

• Automotive grade
• AEC-Q102 qualification
• ROHS3 compliance
• REACH unaffected status
• MSL 3 (168 Hours)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

CSL0902BT1C carries automotive-grade classification with AEC-Q102 qualification, ROHS3 compliance, and REACH unaffected status, confirming suitability for automotive applications requiring regulatory compliance.

CSL0902BT1 maintains identical compliance certifications and electrical characteristics, providing equivalent functionality for direct substitution in automotive and industrial applications.

Both components support surface mount assembly in 0603 package format with identical mechanical footprints, enabling seamless integration into existing PCB designs without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can CSL0902BT1 be used as a direct replacement for CSL0902BT1C?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (3.3V forward voltage, 20mA test current, 360mcd brightness, 470nm wavelength), mechanical dimensions (0603 package, 1.60mm x 0.80mm x 1.34mm max height), and compliance certifications (AEC-Q102, ROHS3, REACH unaffected). Direct substitution is supported without circuit or layout modifications.

Q: Are there differences in automotive qualification between these parts?

A: Both CSL0902BT1C and CSL0902BT1 carry automotive-grade classification with AEC-Q102 qualification. No qualification differences exist between the two parts.

Q: What is the significance of the part number suffix difference (BT1C vs BT1)?

A: The suffix variation reflects internal Rohm Semiconductor product line management. Both suffixes designate the same electrical and mechanical specifications for the 470nm blue LED in 0603 package format. The difference does not indicate performance, reliability, or compliance variations.

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

A: Yes. Identical package format (0603), mounting type (surface mount), and physical dimensions (1.60mm L x 0.80mm W, 1.34mm max height) enable direct PCB footprint compatibility. No assembly process modifications are required.

Q: Are moisture sensitivity levels identical?

A: Yes. Both parts carry MSL 3 (168 Hours) rating, indicating identical moisture handling and storage requirements.

Q: What compliance standards apply to both parts?

A: Both CSL0902BT1C and CSL0902BT1 comply with ROHS3 requirements, carry REACH unaffected status, and meet AEC-Q102 automotive qualification standards.
