Key Parameters

Substitute Part Grouping Explanation

The PL500-16SC-R is identified as a manufacturer-recommended substitute for the PL500-16SI-R. Substitution eligibility is determined by the following critical parameters:

• Identical VCXO type and functional classification
• Matching maximum frequency specification (18MHz)
• Identical output signal types (LVCMOS, TTL)
• Identical supply voltage range (2.25V ~ 3.63V)
• Identical package and case specification (8-SOIC, 0.154", 3.90mm Width)
• Identical surface mount mounting type
• Matching RoHS3 compliance and MSL rating

The primary difference between the main part and substitute is the packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and operating temperature range specification.

Parameter Comparison

Engineering Selection Recommendations

The PL500-16SC-R is a valid substitute for the PL500-16SI-R based on electrical and mechanical parameter equivalence. Both components share identical VCXO functionality, frequency specification, output characteristics, supply voltage range, package configuration, and compliance certifications.

Selection between the main part and substitute should be based on:

• Packaging format requirements: The main part is supplied in Tape & Reel format, while the substitute is available in Cut Tape & Digi-Reel format. Choose based on assembly process and quantity requirements.
• Operating temperature range: The main part operates across -40°C ~ 85°C, while the substitute operates across 0°C ~ 70°C. Applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C must use the main part PL500-16SI-R.
• Inventory availability: The substitute part (2900 Pcs) has higher stock levels compared to the main part (852 Pcs).

Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring environmental and regulatory compatibility.

Frequently Asked Questions (FAQ)

Q: Can PL500-16SC-R replace PL500-16SI-R in all applications?

A: The PL500-16SC-R is electrically and mechanically equivalent to the PL500-16SI-R for applications operating within the 0°C ~ 70°C temperature range. Applications requiring operation below 0°C or above 70°C must use the PL500-16SI-R, which supports -40°C ~ 85°C.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, suitable for high-volume automated assembly. Cut Tape & Digi-Reel packaging provides components on cut tape segments or alternative reel formats, typically for lower-volume or mixed-component assembly processes.

Q: Are the pin configurations identical between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pin configurations, enabling direct PCB footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Both the PL500-16SI-R and PL500-16SC-R are ROHS3 compliant with identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours), ensuring equivalent environmental and regulatory compliance.

Q: What supply voltage range do these oscillators support?

A: Both parts operate with a supply voltage range of 2.25V ~ 3.63V, providing compatibility with standard 3.3V and 2.5V logic systems.
