Substitute Part Grouping Explanation

Substitute parts for the CDC7005RGZRG4 are identified based on strict electrical and mechanical parameter equivalence within the CDC7005 product family. The substitution criteria are:

Electrical Parameters (Must Match):

• Maximum frequency: 800MHz
• Input signal types: LVCMOS, LVPECL
• Output signal type: LVPECL
• Input:Output ratio: 2:5
• Differential input and output capability
• Divider/Multiplier functionality
• Supply voltage range: 3V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C

Mechanical Parameters (Package Compatibility):

• Surface mount mounting type
• RoHS3 compliance
• MSL rating: 3 (168 Hours)

Substitutes are grouped into two categories: MFR Recommended (different package, active status) and Parametric Equivalent (same package family, active status).

Parameter Comparison

Engineering Selection Recommendations

CDC7005RGZT is the primary parametric equivalent for CDC7005RGZRG4. Both devices share identical package geometry (48-VQFN 7x7), electrical specifications, and compliance certifications. The CDC7005RGZT holds Active product status, ensuring long-term availability and manufacturing support. This substitute requires no PCB layout modifications and maintains full functional compatibility.

CDC7005ZVAR is the manufacturer-recommended alternative when package migration is acceptable. This device transitions to a 64-LFBGA (8x8) package while maintaining all electrical parameters and compliance requirements. The CDC7005ZVAR also holds Active product status with significantly higher inventory availability (5022 units). PCB layout redesign is required for this substitution due to the different package footprint and pin configuration.

Both substitutes are ROHS3 compliant with identical MSL ratings, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can CDC7005RGZT be used as a direct replacement for CDC7005RGZRG4?

A: Yes. The CDC7005RGZT is a parametric equivalent with identical electrical specifications, operating parameters, and package dimensions (48-VQFN 7x7). No circuit modifications or PCB redesign are required. The primary difference is product status: CDC7005RGZT is Active while CDC7005RGZRG4 is Obsolete.

Q: What is the difference between CDC7005ZVAR and CDC7005RGZT?

A: Both devices are electrically equivalent with identical functional specifications. The key difference is packaging: CDC7005ZVAR uses a 64-LFBGA (8x8) package, while CDC7005RGZT uses a 48-VQFN (7x7) package. CDC7005ZVAR requires PCB layout redesign due to different pin count and footprint. CDC7005RGZT maintains the same package as the original CDC7005RGZRG4.

Q: Are all three devices compatible with the same circuit design?

A: CDC7005RGZRG4 and CDC7005RGZT are fully compatible without design changes. CDC7005ZVAR requires PCB layout modification due to its different package configuration, though the electrical interface and functional behavior remain identical.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: maximum frequency (800MHz), input signal types (LVCMOS, LVPECL), output signal type (LVPECL), input:output ratio (2:5), differential capability (Yes/Yes), supply voltage range (3V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and compliance certifications (ROHS3, MSL 3).

Q: Why is CDC7005RGZRG4 marked as Obsolete?

A: The CDC7005RGZRG4 is classified as Obsolete by Texas Instruments. Active alternatives within the CDC7005 family (CDC7005RGZT and CDC7005ZVAR) are available for new designs and ongoing production support.
