Substitute Part Grouping Explanation

Substitute parts for the PLL1700E are determined by strict equivalence across the following critical parameters:

• Package / Case: 20-SSOP (0.209", 5.30mm Width)
• Input Type: TTL
• Output Type: CMOS
• Frequency - Max: 36.87MHz
• Ratio - Input:Output: 1:6
• Number of Circuits: 1
• Voltage - Supply: 3.3V, 5V
• Operating Temperature: -25°C ~ 85°C
• Mounting Type: Surface Mount

The PLL1700EG is classified as a parametric equivalent based on identical electrical specifications, functional characteristics, and physical packaging. Both parts share the same base product number (PLL1700) and maintain full compatibility across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the PLL1700E and PLL1700EG are obsolete products. Selection between these parts should be based on inventory availability and compliance requirements. Both components maintain ROHS3 compliance and identical electrical and mechanical specifications, ensuring functional interchangeability in applications requiring PLL multi-clock generation at 36.87MHz with TTL input and CMOS output.

The PLL1700EG variant offers 837 units in current inventory, while the PLL1700E has 1760 units available. Component selection should prioritize availability based on project procurement timelines and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Are PLL1700E and PLL1700EG electrically interchangeable?

A: Yes. Both parts are identical in electrical specifications, including frequency range (36.87MHz), input/output types (TTL/CMOS), supply voltage (3.3V, 5V), and operating temperature range (-25°C ~ 85°C).

Q: Do these parts share the same physical package?

A: Yes. Both components use the 20-SSOP package with 0.209" width and 5.30mm body dimension, enabling direct board-level substitution without layout modifications.

Q: What is the significance of the part number suffix difference (E vs. EG)?

A: The suffix indicates a packaging or manufacturing variant within the same base product line (PLL1700). Both variants maintain identical functional and electrical characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both PLL1700E and PLL1700EG are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: Can these parts be used in new designs?

A: Both parts are classified as obsolete. While they remain available in inventory, new design implementations should evaluate current-generation alternatives from the manufacturer for long-term supply chain sustainability.
