Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the AD7875LPZ. Selection should prioritize parts with active product status to ensure long-term availability and supply chain stability.

AD7875KPZ is the direct variant of the main part number and carries active product status. This part is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements.

AD7870 series parts (AD7870JPZ, AD7870KPZ, AD7870LPZ) are functionally equivalent alternatives from the same manufacturer. All three variants are active products with ROHS3 compliance and REACH unaffected status. These parts provide additional inventory availability across multiple temperature grades and packaging options.

For new designs or long-term production, AD7875KPZ or any AD7870 series variant are recommended due to active product status and regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can AD7870 series parts directly replace AD7875LPZ?

A: Yes. AD7870JPZ, AD7870KPZ, and AD7870LPZ are parametrically equivalent to AD7875LPZ across all electrical specifications, sampling rate, resolution, input configuration, data interface, supply voltages, operating temperature range, and physical packaging. Direct substitution is supported without circuit modification.

Q: What is the difference between AD7875KPZ and AD7870 variants?

A: Both AD7875KPZ and AD7870 series parts meet identical electrical and mechanical specifications. The primary difference is the base product number designation (AD7875 versus AD7870). All parts are active products with equivalent performance characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: AD7875KPZ, AD7870JPZ, AD7870KPZ, and AD7870LPZ are all ROHS3 compliant. The original AD7875LPZ does not list RoHS status due to its obsolete classification.

Q: Does packaging differ between substitute parts?

A: All substitute parts use identical 28-PLCC (11.51x11.51) surface mount packaging. Moisture sensitivity level is MSL 3 (168 Hours) across all parts, ensuring consistent handling and storage requirements.

Q: Which substitute part offers the best inventory availability?

A: AD7870LPZ currently has the highest inventory level at 1027 pieces. AD7870JPZ has 2000 pieces available. Both are active products suitable for immediate procurement.
