Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FA1112C-TR is determined by the following criteria:

Primary Compatibility Parameters:

• Color: Orange (605nm dominant wavelength range)
• Package / Case: 0603 (1608 Metric)
• Mounting Type: Surface Mount
• Lens Transparency: Diffused
• Size / Dimension: 1.60mm L x 0.80mm W

Allowable Variation Parameters:

• Voltage - Forward (Vf): Within circuit design tolerance (1.9V nominal acceptable range)
• Millicandela Rating: Higher output acceptable for indication applications
• Height (Max): Variation acceptable within PCB assembly constraints
• Moisture Sensitivity Level (MSL): Variation acceptable based on storage and assembly conditions

The identified substitute parts maintain the core optical and mechanical specifications while offering active product status and improved availability.

Engineering Selection Recommendations

SML-E12D8WT86 (Rohm Semiconductor) - Direct Substitute:

This component is classified as a direct substitute based on matching package, color, dominant wavelength, and mounting specifications. The forward voltage increases from 1.9V to 2.2V, requiring circuit design verification to confirm compatibility with existing current-limiting resistor values. The millicandela rating of 100mcd exceeds the original 50mcd specification, providing enhanced brightness for indication applications. The component is ROHS3 compliant and maintains active product status with substantial inventory availability (47,581 pcs). Height reduction to 0.46mm improves PCB assembly clearance margins.

HSML-C197 (Broadcom Limited) - Similar Substitute:

This component maintains the original forward voltage specification of 1.9V, eliminating circuit redesign requirements. The millicandela rating of 90mcd provides increased brightness over the original 50mcd. The component is ROHS3 compliant and maintains active product status with strong inventory availability (26,741 pcs). Height reduction to 0.40mm provides maximum PCB assembly clearance. Moisture sensitivity level of 2A (4 Weeks) represents improved handling characteristics compared to the original MSL 4 (72 Hours).

Both substitute parts satisfy the core functional requirements of the FA1112C-TR within the allowable parameter variation range for orange LED indication applications in the 0603 (1608 Metric) surface mount package.

Frequently Asked Questions (FAQ)

Q: Can SML-E12D8WT86 be used as a direct replacement without circuit modification?

A: The SML-E12D8WT86 operates at 2.2V forward voltage compared to the FA1112C-TR specification of 1.9V. Circuit verification is required to confirm that existing current-limiting resistor values accommodate this voltage increase while maintaining the 20mA test current specification.

Q: What is the primary difference between the two substitute options?

A: The HSML-C197 maintains the original 1.9V forward voltage specification, requiring no circuit modification. The SML-E12D8WT86 operates at 2.2V and requires circuit design verification. Both components provide increased millicandela output and active product status.

Q: Are the substitute parts compatible with existing PCB layouts designed for FA1112C-TR?

A: Yes. Both substitute parts conform to the 0603 (1608 Metric) package specification with identical footprint dimensions of 1.60mm L x 0.80mm W. The reduced maximum heights (0.46mm for SML-E12D8WT86 and 0.40mm for HSML-C197 versus 0.55mm for FA1112C-TR) provide improved assembly clearance.

Q: Do the substitute parts meet regulatory compliance requirements?

A: Both SML-E12D8WT86 and HSML-C197 are ROHS3 compliant and REACH unaffected. Both carry EAR99 export classification and 8541.41.0000 HTSUS code, matching the regulatory profile of the original FA1112C-TR.

Q: What is the impact of increased millicandela rating on circuit operation?

A: The substitute parts provide 90mcd to 100mcd output compared to the original 50mcd. For indication applications, this increased brightness is functionally acceptable. Circuit current limiting remains at the 20mA test specification, ensuring component reliability.

Q: How do moisture sensitivity levels affect component handling?

A: The HSML-C197 specifies MSL 2A (4 Weeks), providing extended dry storage capability compared to the original MSL 4 (72 Hours). The SML-E12D8WT86 specifies MSL 3 (168 Hours), offering intermediate storage duration. Both represent improved handling characteristics for manufacturing environments.
