XTC7006 TCXO Oscillator - Equivalent & Substitute Parts

Part Overview

The XTC7006 is a 26 MHz temperature-compensated crystal oscillator (TCXO) manufactured by Murata Electronics, designed for applications requiring stable frequency output with clipped sine wave characteristics. This component operates at 3V supply voltage with ±500ppb frequency stability across an operating temperature range of -30°C to 85°C.

The XTC7006 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance of systems utilizing this oscillator.

Engineering Selection Recommendations

The ATXAIG-11-A-26.000MHZ-E05-T3 is a direct equivalent substitute for the XTC7006. Both parts meet identical electrical and mechanical specifications across all critical parameters. The Abracon part carries AEC-Q200 automotive qualification and REACH compliance status, providing additional assurance for regulated applications.

The primary advantage of selecting the ATXAIG-11-A-26.000MHZ-E05-T3 is its active product status and confirmed availability. The XTC7006's obsolete classification makes the Abracon equivalent the appropriate choice for new designs, production continuity, and component replenishment.

The maximum supply current of the Abracon part (2mA) is higher than the Murata specification (1.5mA). This difference is acceptable in applications where the original design accommodates this tolerance, as the increase remains within typical power budget margins for oscillator circuits.

Frequently Asked Questions (FAQ)

Q: Can the ATXAIG-11-A-26.000MHZ-E05-T3 be used as a direct replacement for the XTC7006 without circuit modification?

A: Yes. Both parts share identical electrical characteristics (frequency, stability, output type, supply voltage, operating temperature range) and mechanical specifications (package, dimensions, height). No circuit modifications are required for substitution.

Q: What is the significance of the higher maximum supply current in the Abracon part?

A: The ATXAIG-11-A-26.000MHZ-E05-T3 specifies 2mA maximum supply current compared to the XTC7006's 1.5mA. This difference reflects typical manufacturing variations between vendors. Provided the original circuit design accommodates oscillator current draw within normal operating margins, this specification difference does not prevent substitution.

Q: Are there any compliance or certification differences between these parts?

A: The Abracon ATXAIG-11-A-26.000MHZ-E05-T3 carries AEC-Q200 automotive qualification and REACH compliance status. Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The additional certifications on the Abracon part provide enhanced qualification for regulated or automotive applications.

Q: What packaging options are available for the substitute part?

A: The ATXAIG-11-A-26.000MHZ-E05-T3 is supplied in Tape & Reel (TR) packaging. The XTC7006 packaging format was not specified in the original documentation. Confirm packaging requirements with your procurement process.

Q: Why is the XTC7006 classified as obsolete?

A: Murata Electronics has discontinued the XTC7006 product line. The ATXAIG-11-A-26.000MHZ-E05-T3 from Abracon remains in active production and is the recommended equivalent for ongoing supply and new designs.
