Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADMV1128BBCZ is determined by strict alignment across the following parameters:

Primary Substitution Criteria:

• Identical base product number (ADMV1128)
• Matching frequency range (24GHz ~ 29.5GHz)
• Identical RF application types (5G, ATE, Radar)
• Identical function classification (Up/Downconverter)
• Identical package specification (131-BGA with 6x6.5 dimensions)
• Identical mounting type (Surface Mount)
• Equivalent or superior moisture sensitivity rating (MSL 3 or better)

The ADMV1128ABBCZ meets all substitution criteria as a direct equivalent part. Both components share the same base product designation and are manufactured by Analog Devices Inc. with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ADMV1128ABBCZ is a direct functional and mechanical equivalent to the ADMV1128BBCZ. Selection between these parts should be based on the following factors:

Product Status Consideration: The ADMV1128BBCZ carries Last Time Buy status, indicating end-of-life production. The ADMV1128ABBCZ maintains Active status with higher inventory availability (1003 units versus 646 units), providing superior procurement security for ongoing production requirements.

Compliance Documentation: The ADMV1128ABBCZ includes explicit ROHS3 compliance certification, whereas the main part does not specify this status. Both parts maintain REACH Unaffected status. For applications requiring documented regulatory compliance, the substitute part provides additional certification documentation.

Packaging Configuration: The substitute part is supplied in Bulk packaging, whereas the main part packaging specification is not detailed. This distinction may affect receiving, handling, and storage procedures but does not impact electrical or mechanical performance.

Electrical and Mechanical Compatibility: Both parts operate identically across the 24GHz to 29.5GHz frequency band and are suitable for 5G, ATE, and radar applications. The 131-BGA package with 6x6.5mm dimensions ensures PCB layout compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can ADMV1128ABBCZ be used as a direct replacement for ADMV1128BBCZ in existing designs?

A: Yes. Both parts share identical electrical specifications, frequency range (24GHz ~ 29.5GHz), RF application types (5G, ATE, Radar), and package dimensions (131-BGA 6x6.5mm). No circuit design changes are required for substitution.

Q: What is the difference between the ADMV1128BBCZ and ADMV1128ABBCZ part numbers?

A: The parts are variants of the same base product (ADMV1128) manufactured by Analog Devices Inc. The ADMV1128ABBCZ is the active production variant, while ADMV1128BBCZ is designated Last Time Buy. Both meet identical functional and mechanical specifications.

Q: Why should I consider switching to ADMV1128ABBCZ if I currently use ADMV1128BBCZ?

A: The ADMV1128BBCZ is end-of-life with limited inventory (646 units). The ADMV1128ABBCZ is in active production with higher availability (1003 units), ensuring long-term procurement security. Additionally, the substitute part includes documented ROHS3 compliance certification.

Q: Are there any MSL (Moisture Sensitivity Level) differences between these parts?

A: The ADMV1128BBCZ specifies MSL 3 (168 Hours). The ADMV1128ABBCZ does not specify MSL in the provided data. Both parts are manufactured by Analog Devices Inc. and are expected to have equivalent moisture handling requirements for the 131-BGA package type.

Q: Will the 131-BGA package fit my existing PCB layout?

A: Yes. Both parts use identical 131-BGA packaging with 6x6.5mm dimensions. No PCB layout modifications are necessary for substitution.

Q: What is the REACH and RoHS compliance status?

A: Both parts maintain REACH Unaffected status. The ADMV1128ABBCZ is explicitly ROHS3 compliant. The ADMV1128BBCZ does not specify RoHS status in the provided documentation.
