Engineering Selection Recommendations

The TC7109CLW713 is classified as obsolete. Both substitute parts—TC7109CLW and TC7109ACLW713—are active products from Microchip Technology and maintain full electrical and mechanical compatibility with the original design.

TC7109CLW is supplied in tube packaging and carries ROHS3 compliance certification. This option is suitable for applications where RoHS compliance is required and standard tube packaging is acceptable for procurement and assembly workflows.

TC7109ACLW713 is supplied in tape & reel (TR) format and also carries ROHS3 compliance certification. This packaging format is optimized for automated assembly processes and high-volume production environments.

Both substitutes are functionally equivalent to the TC7109CLW713 and require no circuit modifications or design changes. Selection between the two substitutes should be based on packaging requirements, supply chain preferences, and production assembly methodology.

Frequently Asked Questions (FAQ)

Q: Can TC7109CLW and TC7109ACLW713 be used interchangeably with TC7109CLW713?

A: Yes. Both substitute parts maintain identical electrical specifications and mechanical compatibility. The primary differences are product status (active vs. obsolete), RoHS compliance certification, and packaging format (tube vs. tape & reel). No circuit modifications are required.

Q: What is the difference between TC7109CLW and TC7109ACLW713?

A: Both parts are functionally identical 12-bit dual-slope ADCs with matching electrical parameters. The difference is packaging format: TC7109CLW is supplied in tube packaging, while TC7109ACLW713 is supplied in tape & reel format. Selection depends on assembly process requirements and procurement preferences.

Q: Why is the TC7109CLW713 marked as obsolete?

A: The TC7109CLW713 has reached end-of-life status from Microchip Technology. Active alternatives (TC7109CLW and TC7109ACLW713) are available to support continued design implementation and production requirements.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. All three parts share identical pin configurations, electrical characteristics, and mechanical dimensions. Direct substitution is possible without PCB redesign or circuit modification.

Q: What does ROHS3 compliance mean for these substitute parts?

A: ROHS3 compliance indicates that TC7109CLW and TC7109ACLW713 meet Restriction of Hazardous Substances (RoHS) directives, restricting the use of specific hazardous materials in electrical and electronic equipment. The original TC7109CLW713 is RoHS non-compliant. If RoHS compliance is a design requirement, either substitute part is acceptable.

Q: Which substitute should I select for high-volume production?

A: TC7109ACLW713 in tape & reel format is optimized for automated assembly processes typical in high-volume manufacturing. TC7109CLW in tube packaging is suitable for lower-volume or manual assembly workflows.
