PBA000008 Equivalent & Substitute Parts

Part Overview

The PBA000008 is a 100 MHz XO (Standard) PECL Oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ PB series. This surface mount crystal oscillator operates at 3.3V with enable/disable functionality, designed for applications requiring stable 100 MHz frequency output in PECL logic format. The device is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications allow direct replacement while maintaining system performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PBA000008 is determined by the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output Format: PECL (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Package: 6-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm footprint (exact match required)
• Supply Current: 88mA maximum (exact match required)
• Disable Current: 30µA maximum (exact match required)

The PBA000009 qualifies as a manufacturer-recommended substitute based on matching all critical electrical and mechanical parameters. Variations in frequency stability and operating temperature range do not preclude substitution when system design margins accommodate these differences.

Parameter Comparison

Engineering Selection Recommendations

Both PBA000008 and PBA000009 are Active status products from Diodes Incorporated with identical ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific requirements:

The PBA000008 provides tighter frequency stability at ±25ppm with a narrower operating temperature range of -20°C to 70°C. This configuration suits applications with controlled thermal environments and stringent frequency accuracy demands.

The PBA000009 offers extended operating temperature range from -40°C to 85°C with ±50ppm frequency stability. This configuration accommodates wider environmental conditions and applications where broader temperature operation is required.

Both parts maintain identical electrical performance in terms of supply current, disable current, and output characteristics. Physical footprint and package compatibility are identical, enabling direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can PBA000009 directly replace PBA000008 on existing PCBs?

A: Yes. Both parts use identical 6-SMD, No Lead packaging with 7.00mm x 5.00mm x 2.00mm maximum dimensions. No PCB layout or footprint modifications are required for substitution.

Q: What are the key differences between these parts?

A: The primary differences are frequency stability tolerance (±25ppm vs ±50ppm) and operating temperature range (-20°C to 70°C vs -40°C to 85°C). All other electrical and mechanical specifications are identical.

Q: Which part should I select for high-temperature applications?

A: The PBA000009 supports operating temperatures up to 85°C, making it suitable for applications requiring extended thermal operation. The PBA000008 is limited to 70°C maximum.

Q: Are both parts ROHS3 compliant?

A: Yes. Both PBA000008 and PBA000009 are ROHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Do these parts have identical supply current specifications?

A: Yes. Both parts draw a maximum of 88mA during normal operation and 30µA maximum during disable mode, providing identical power consumption characteristics.

Q: What is the significance of frequency stability differences?

A: Frequency stability tolerance affects long-term frequency accuracy. The PBA000008 at ±25ppm provides tighter tolerance suitable for precision timing applications. The PBA000009 at ±50ppm is acceptable for general-purpose oscillator applications where broader tolerance is acceptable.
