Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TA50000006 are categorized into two groups based on substitution compatibility:

Group 1: Direct Substitutes (Crystal-Based Resonators)

Direct substitutes maintain electrical and mechanical compatibility with the TA50000006 through matching core parameters:

• Frequency: 50 MHz
• Output: CMOS
• Voltage - Supply: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±50ppm
• Operating Temperature: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, No Lead
• Size / Dimension: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

These parts differ from the TA50000006 in base resonator technology (Crystal instead of MEMS) and have slightly increased maximum seated heights (1.80mm to 1.90mm versus 1.00mm). All Group 1 substitutes maintain Active product status.

Group 2: Similar Substitute (MEMS-Based Resonator)

The ASVMPC-50.000MHZ-Z-T shares the MEMS resonator technology with the TA50000006 but introduces variations in package configuration and electrical specifications:

• Frequency: 50 MHz
• Output: CMOS
• Function: Enable/Disable
• Mounting Type: Surface Mount
• Size / Dimension: 0.276" L x 0.197" W (7.00mm x 5.00mm)

Key differences include: 6-SMD package with exposed pad (versus 4-SMD, No Lead), wider voltage supply range (2.25V ~ 3.6V versus 3.3V), extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C), and reduced maximum seated height (0.90mm versus 1.00mm).

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical and Mechanical Compatibility:

The crystal-based oscillators in Group 1 (510CAA50M0000AAGR, CO4305-50.000-EXT-T-TR, CPPC7L-A7BP-50.0TS, CPPC7LT-A7BP-50.0TS, CPPLC7L-A7BP-50.0TS, and SXO75C3A481-50.000M) provide the most straightforward substitution path. All maintain the core electrical specifications: 50 MHz frequency, CMOS output, 3.3V supply, Enable/Disable function, ±50ppm frequency stability, and -40°C to 85°C operating temperature range.

All Group 1 substitutes carry Active product status, ensuring long-term availability and manufacturing support. The CO4305-50.000-EXT-T-TR, CPPC7L-A7BP-50.0TS, CPPC7LT-A7BP-50.0TS, CPPLC7L-A7BP-50.0TS, and SXO75C3A481-50.000M are ROHS3 Compliant, meeting environmental regulatory requirements.

Height Consideration for PCB Layout:

The TA50000006 has a maximum seated height of 1.00mm. Group 1 substitutes have increased heights: 510CAA50M0000AAGR and CO4305-50.000-EXT-T-TR at 1.80mm, CPPC7L-A7BP-50.0TS, CPPC7LT-A7BP-50.0TS, and CPPLC7L-A7BP-50.0TS at 1.90mm, and SXO75C3A481-50.000M at 1.60mm. PCB clearance must accommodate these height variations.

For Extended Temperature Range Applications:

The ASVMPC-50.000MHZ-Z-T (Group 2) extends the operating temperature range to -55°C to 125°C and provides a lower maximum seated height of 0.90mm. However, this part uses a 6-SMD package with exposed pad instead of the 4-SMD, No Lead configuration, requiring PCB layout modification. The voltage supply range is also wider (2.25V ~ 3.6V), providing flexibility for systems with variable supply voltages.

Inventory and Availability:

SXO75C3A481-50.000M offers the highest inventory level (4,079 pieces) among all substitutes, supporting high-volume procurement requirements. ASVMPC-50.000MHZ-Z-T provides 1,771 pieces, while crystal-based alternatives range from 754 to 950 pieces.

Frequently Asked Questions (FAQ)

Q1: Can I directly replace TA50000006 with any of the Group 1 crystal-based substitutes without PCB modification?

A: Yes, for electrical functionality. All Group 1 substitutes maintain identical electrical specifications and the same 4-SMD, No Lead package footprint. However, the increased maximum seated heights (1.60mm to 1.90mm versus 1.00mm) require verification of PCB clearance above the component. If vertical space is constrained, PCB layout review is necessary.

Q2: What is the primary difference between the TA50000006 and the ASVMPC-50.000MHZ-Z-T?

A: Both use MEMS resonator technology, but differ in package configuration and operating specifications. The ASVMPC-50.000MHZ-Z-T uses a 6-SMD package with exposed pad (versus 4-SMD, No Lead), operates across -55°C to 125°C (versus -40°C to 85°C), accepts 2.25V to 3.6V supply (versus 3.3V), and has a lower maximum seated height of 0.90mm. These differences require PCB layout changes and are suitable for applications requiring extended temperature range.

Q3: Are all substitute parts RoHS compliant?

A: The crystal-based Group 1 substitutes (CO4305-50.000-EXT-T-TR, CPPC7L-A7BP-50.0TS, CPPC7LT-A7BP-50.0TS, CPPLC7L-A7BP-50.0TS, and SXO75C3A481-50.000M) are ROHS3 Compliant. The Skyworks 510CAA50M0000AAGR does not specify RoHS status in the provided data. The ASVMPC-50.000MHZ-Z-T is ROHS3 Compliant. Verify RoHS compliance requirements for your specific application before final selection.

Q4: Which substitute offers the best height compatibility with the original TA50000006?

A: The SXO75C3A481-50.000M has the lowest maximum seated height among Group 1 substitutes at 1.60mm, closest to the original 1.00mm. The ASVMPC-50.000MHZ-Z-T (Group 2) offers the lowest height at 0.90mm but requires package reconfiguration from 4-SMD to 6-SMD with exposed pad.

Q5: What is the frequency stability specification for the ASVMPC-50.000MHZ-Z-T?

A: The frequency stability specification is not provided in the available data for the ASVMPC-50.000MHZ-Z-T. Contact the manufacturer (Abracon LLC) for detailed frequency stability information if this parameter is critical for your application.

Q6: Can I use these substitutes in high-volume production immediately?

A: All substitute parts carry Active product status, confirming ongoing manufacturing and availability. However, conduct design validation testing to confirm performance in your specific circuit topology, particularly regarding frequency stability, phase noise, and enable/disable timing characteristics, before committing to high-volume production.
