Substitute Part Grouping Explanation

Substitution for the ASGTX-C-12.800MHZ-2-T is determined by strict equivalence across the following critical parameters:

• Frequency: 12.8 MHz (exact match required)
• Type: VCTCXO (voltage controlled oscillator function)
• Output: LVCMOS (logic voltage compatible output)
• Supply Voltage: 3.135V ~ 3.465V (operating range match)
• Frequency Stability: ±2ppm (performance specification)
• Operating Temperature: -40°C ~ 85°C (environmental range)
• Maximum Supply Current: 45mA (power consumption)
• Package / Case: 6-SMD, No Lead (physical and electrical footprint)
• Dimensions: 9.00mm x 7.00mm x 2.24mm (board layout compatibility)

Two substitute parts meet all these criteria and are available from Abracon LLC within the ASGTX series. Both maintain identical electrical specifications and physical packaging, with the primary distinction being product status and manufacturing revision level.

Frequently Asked Questions (FAQ)

Q: Can ASGTX-C-12.800MHZ-2 be used as a direct replacement for ASGTX-C-12.800MHZ-2-T?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including frequency, output type, supply voltage, frequency stability, operating temperature range, current consumption, and package dimensions. The primary difference is product status: the substitute is Active while the original is Discontinued.

Q: What is the difference between ASGTX-C-12.800MHZ-2 and ASGTX-C-12.800MHZ-2-T2?

A: Both parts are parametric equivalents with identical electrical specifications and physical packaging. The difference is manufacturing revision level, indicated by the "-T2" suffix. Both are Active products with equivalent availability and compliance certifications.

Q: Are there any compatibility concerns with PCB layout or assembly?

A: No. All three parts share identical package specifications (6-SMD, No Lead) and dimensions (9.00mm x 7.00mm x 2.24mm maximum height). No PCB redesign or assembly process modification is required.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. Both ASGTX-C-12.800MHZ-2 and ASGTX-C-12.800MHZ-2-T2 are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level), matching the original part's compliance profile.

Q: What is the frequency stability specification, and is it maintained across all three parts?

A: Frequency stability is ±2ppm across all three parts. This specification is maintained for the operating temperature range of -40°C to 85°C.

Q: Can these parts be used interchangeably in production?

A: Yes. Since both substitute parts are Active products with identical electrical and mechanical specifications, they can be used interchangeably in production without design or process changes. Component selection may be based on inventory availability and supplier lead times.
