Substitute Part Grouping Explanation

Substitute parts for the PLL1700EG are identified based on strict parametric equivalence. The following criteria determine substitution eligibility:

• Identical PLL functionality and multi-clock generator architecture
• Matching maximum frequency specification (36.87MHz)
• Identical input type (TTL) and output type (CMOS)
• Matching input-to-output ratio (1:6)
• Identical number of circuits (1)
• Compatible supply voltage range (3.3V, 5V)
• Matching operating temperature range (-25°C ~ 85°C)
• Identical package type (20-SSOP with 0.209", 5.30mm Width)
• Surface mount mounting type

The PLL1700E meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The PLL1700E serves as a direct parametric equivalent to the PLL1700EG. Both components are obsolete products from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on component availability and inventory status. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the PLL1700E directly replace the PLL1700EG in existing designs?

A: Yes. The PLL1700E is a parametric equivalent with identical electrical specifications, frequency range, input/output characteristics, supply voltage requirements, operating temperature range, and 20-SSOP package dimensions. Direct substitution is supported without design modification.

Q: Are there any differences in the package footprint between these parts?

A: No. Both the PLL1700EG and PLL1700E use the identical 20-SSOP package with 0.209" width and 5.30mm body width, ensuring PCB layout compatibility.

Q: What is the significance of the obsolete product status?

A: Both parts are classified as obsolete by Texas Instruments. This status indicates that these components are no longer in active production. Procurement should prioritize available inventory from authorized distributors.

Q: Do both parts meet current environmental compliance requirements?

A: Yes. Both the PLL1700EG and PLL1700E are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and use.

Q: Is there a difference in moisture sensitivity between these parts?

A: No. Both components have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
