Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD650JN is determined by strict equivalence across the following critical parameters:

• Functional Type: Volt to Frequency and Frequency to Volt Converter
• Frequency Rating: 1 MHz maximum operating frequency
• Linearity Specification: ±0.1%
• Temperature Coefficient: ±150ppm/°C
• Package Format: 14-DIP (0.300", 7.62mm)
• Mounting Configuration: Through Hole
• Base Product Series: AD650

The AD650JNZ qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format, with AD650JNZ currently in active production status.

Parameter Comparison

Engineering Selection Recommendations

The AD650JNZ serves as the direct functional equivalent to the obsolete AD650JN. Both components share identical electrical performance specifications and physical package dimensions, ensuring pin-for-pin compatibility in Through Hole PCB applications.

The AD650JNZ is the recommended selection for new designs and ongoing procurement due to its active product status and documented compliance certifications. The part maintains ROHS3 compliance and REACH unaffected status, supporting modern regulatory requirements for electronic component manufacturing and distribution.

For legacy system maintenance where AD650JN inventory is unavailable, the AD650JNZ provides equivalent performance without circuit redesign or PCB modification requirements.

Frequently Asked Questions (FAQ)

Q: Is the AD650JNZ a direct pin-for-pin replacement for the AD650JN?

A: Yes. Both components utilize the 14-DIP (0.300", 7.62mm) Through Hole package with identical pinout configuration. No PCB layout modifications are required for substitution.

Q: What is the primary difference between AD650JN and AD650JNZ?

A: The AD650JN is classified as obsolete, while the AD650JNZ maintains active production status. Electrical specifications and package format are identical. The AD650JNZ includes documented ROHS3 compliance and REACH unaffected status.

Q: Can the AD650JNZ be used in applications originally designed for the AD650JN?

A: Yes. Identical frequency rating (1 MHz), linearity (±0.1%), temperature coefficient (±150ppm/°C), and package configuration ensure functional equivalence across all specified operating parameters.

Q: What packaging formats are available for the AD650 series?

A: The AD650JN is supplied in bulk format, while the AD650JNZ is available in Tube packaging. Both utilize the same 14-DIP Through Hole package case.

Q: Are there any compliance differences between these parts?

A: The AD650JNZ includes ROHS3 compliance and REACH unaffected certification. The AD650JN specifications do not document these compliance statuses.
