Substitute Part Grouping Explanation

Substitution of the SPH1611LR5F is based on the following criteria derived from provided specifications:

• Manufacturer alignment: Knowles SiSonic™ series components maintain consistent design philosophy and manufacturing standards
• Regulatory compliance: Matching ECCN (EAR99) and HTSUS (8518.10.8030) classifications ensure equivalent export and tariff treatment
• Moisture sensitivity: MSL 1 (Unlimited) rating indicates no moisture-related handling restrictions; substitute parts must maintain this classification
• Product status: Active status of substitute components ensures ongoing availability and supply chain continuity
• Microphone type: MEMS (Silicon) technology within the SiSonic™ series provides functional equivalence for analog microphone applications

Engineering Selection Recommendations

The SPH6611LR5H-1 is the manufacturer-recommended substitute for the obsolete SPH1611LR5F. Selection is based on:

• Regulatory equivalence: Both components share identical ECCN and HTSUS classifications, ensuring compliance with export and tariff requirements
• Moisture handling: Matching MSL 1 rating eliminates moisture-related processing constraints for both components
• Supply continuity: The SPH6611LR5H-1 maintains active product status with 22,100 units in new original stock, providing reliable long-term availability compared to the obsolete SPH1611LR5F
• Compliance certification: ROHS3 compliance of the substitute component satisfies environmental and regulatory requirements for current manufacturing standards

Frequently Asked Questions (FAQ)

Q: What makes SPH6611LR5H-1 a suitable substitute for SPH1611LR5F?

A: Both components are manufactured by Knowles and share identical regulatory classifications (ECCN EAR99, HTSUS 8518.10.8030) and moisture sensitivity ratings (MSL 1). The SPH6611LR5H-1 is the manufacturer-recommended replacement and maintains active product status, ensuring supply chain continuity.

Q: Are there any compliance differences between the two parts?

A: No. Both components carry identical ECCN and HTSUS codes. The SPH6611LR5H-1 additionally carries ROHS3 compliance certification, which represents an enhancement for current environmental standards.

Q: What is the moisture sensitivity implication for handling?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture-related handling or baking requirements prior to soldering. Standard storage conditions are applicable to both components.

Q: How does the active status of SPH6611LR5H-1 affect procurement?

A: Active product status ensures the substitute component remains in production and available through authorized distributors. The obsolete status of SPH1611LR5F limits future procurement options, making transition to the active substitute necessary for sustained production requirements.

Q: Are there dimensional or termination considerations for PCB integration?

A: The SPH6611LR5H-1 specifies solder pad termination with dimensions of 0.138" L x 0.104" W (4.60mm x 2.65mm) and maximum height of 0.043" (1.08mm). PCB layout and assembly processes must accommodate these specifications. Detailed dimensional data for the SPH1611LR5F is not provided in available documentation.
