Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TA-80.000MCD-T is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 80 MHz
• Output Type: CMOS
• Function: Enable/Disable
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Compatible Variation Parameters:

• Supply Voltage: 2.5V (exact match) or 2.5V within a wider range (2.25V ~ 3.6V)
• Base Resonator Type: MEMS or Crystal (both acceptable for XO standard oscillators)
• Package / Case: 4-SMD, No Lead or 6-SMD, No Lead Exposed Pad (same footprint family, different pin count)
• Physical Dimensions: 7.00mm x 5.00mm (standard, may vary in height)
• Frequency Stability: ±25ppm or tighter tolerance

Substitute parts are classified into two categories: Direct Manufacturer Substitutes (functionally identical crystal-based alternatives) and Similar Manufacturer Substitutes (MEMS-based alternatives with expanded voltage range).

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Substitutes (Skyworks Si510 Series):

The 510GBA80M0000AAGR and 510GBB80M0000AAGR are crystal-based oscillators that provide direct functional equivalence to the TA-80.000MCD-T. Both parts maintain identical frequency (80 MHz), output type (CMOS), supply voltage (2.5V), function (Enable/Disable), frequency stability (±25ppm), and operating temperature range (-40°C ~ 85°C). Both are housed in 4-SMD, No Lead packages with matching 7.00mm x 5.00mm footprints.

Key differences are limited to increased seated height (1.80mm versus 1.00mm) and specified maximum supply current (26mA). Both parts carry Active product status and ROHS3 compliance certification. The 510GBB80M0000AAGR variant offers higher inventory availability (1111 Pcs) compared to 510GBA80M0000AAGR (892 Pcs).

Similar Manufacturer Substitute (Abracon ASVMPC Series):

The ASVMPC-80.000MHZ-LR-T is a MEMS-based oscillator maintaining the same resonator technology as the original TA-80.000MCD-T. This part matches frequency (80 MHz), output type (CMOS), function (Enable/Disable), and operating temperature range (-40°C ~ 85°C). The supply voltage range (2.25V ~ 3.6V) encompasses the 2.5V requirement, providing broader voltage compatibility.

The ASVMPC variant differs in package configuration (6-SMD, No Lead Exposed Pad versus 4-SMD, No Lead), resulting in different pin assignments. Seated height is lower (0.90mm), and maximum supply current is higher (35mA). Frequency stability is not specified in available documentation. The part carries Active product status and ROHS3 compliance certification.

Selection Criteria:

For direct pin-compatible replacement with identical electrical characteristics, select either 510GBA80M0000AAGR or 510GBB80M0000AAGR. For applications requiring MEMS resonator technology with expanded voltage tolerance and lower profile, select ASVMPC-80.000MHZ-LR-T, contingent upon PCB layout accommodation of the 6-SMD package variant.

Frequently Asked Questions (FAQ)

Q: Can the Skyworks Si510 crystal-based oscillators directly replace the TXC MEMS oscillator?

A: Yes. The 510GBA80M0000AAGR and 510GBB80M0000AAGR provide direct functional substitution. Both maintain identical frequency (80 MHz), CMOS output, 2.5V supply voltage, Enable/Disable function, ±25ppm frequency stability, and -40°C ~ 85°C operating range. The primary physical difference is increased seated height (1.80mm versus 1.00mm). PCB clearance verification is required.

Q: What is the difference between 510GBA80M0000AAGR and 510GBB80M0000AAGR?

A: Both parts are functionally identical 80 MHz CMOS oscillators with matching electrical specifications. The designations reflect different internal configurations (base product numbers 510GBA versus 510GBB). Selection between these variants should be based on procurement availability and supply chain considerations. The 510GBB variant currently has higher inventory (1111 Pcs versus 892 Pcs).

Q: Why does the Abracon ASVMPC-80.000MHZ-LR-T have a different package (6-SMD versus 4-SMD)?

A: The ASVMPC uses a 6-SMD, No Lead Exposed Pad configuration compared to the 4-SMD, No Lead package of the original part. This difference reflects different internal circuit architecture and thermal management design. The exposed pad in the 6-SMD package provides enhanced thermal dissipation. PCB layout redesign is required for this substitution.

Q: Is the Abracon ASVMPC-80.000MHZ-LR-T compatible with 2.5V supply voltage?

A: Yes. The ASVMPC operates across a 2.25V ~ 3.6V supply voltage range, which encompasses the 2.5V requirement. This wider voltage tolerance provides additional design flexibility for applications with variable supply conditions.

Q: What are the compliance certifications for substitute parts?

A: The Skyworks 510GBA80M0000AAGR and Abracon ASVMPC-80.000MHZ-LR-T both carry ROHS3 compliance certification. All parts (original and substitutes) are classified as EAR99 for export control purposes and carry HTSUS code 8542.39.0001. Moisture Sensitivity Level is 1 (Unlimited) for all parts.

Q: Are there any frequency stability differences between the substitutes?

A: The Skyworks Si510 series (both 510GBA and 510GBB variants) maintain ±25ppm frequency stability, matching the original TA-80.000MCD-T specification. Frequency stability for the Abracon ASVMPC-80.000MHZ-LR-T is not specified in available technical documentation and should be verified with the manufacturer for applications requiring defined stability parameters.

Q: What is the maximum supply current for each substitute?

A: The Skyworks Si510 series specifies 26mA maximum supply current (Enable mode) and 18mA maximum in Disable mode. The Abracon ASVMPC specifies 35mA maximum supply current (Enable mode) and 22mA maximum in Disable mode. The original TA-80.000MCD-T does not specify supply current in available documentation.
