125 MHz CMOS Crystal Oscillator 7WA2572007 Equivalent & Substitute Parts

Part Overview

The TXC CORPORATION 7WA2572007 is a 125 MHz XO (Standard) CMOS oscillator with 3.3V supply, Enable/Disable function, and 4-SMD surface mount packaging. This part operates across the industrial temperature range of -40°C to 85°C with ±50ppm frequency stability and is classified as Obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are required for new designs and ongoing production requirements. All substitute parts maintain identical electrical specifications and mechanical compatibility with the original design.

Substitute Part Grouping Explanation

Substitution eligibility for the 7WA2572007 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Frequency: 125.0000 MHz
Output: CMOS
Supply Voltage: 3.3V
Function: Enable/Disable
Frequency Stability: ±50ppm
Operating Temperature: -40°C to 85°C
Package/Case: 4-SMD, No Lead

Frequently Asked Questions (FAQ)

Q: Can the 7WA2572007 be directly replaced with any of these substitute parts?

A: Yes. All five substitute parts are direct functional equivalents. They share identical frequency (125 MHz), output type (CMOS), supply voltage (3.3V), Enable/Disable function, frequency stability (±50ppm), operating temperature range (-40°C to 85°C), and 4-SMD surface mount package dimensions (7.00mm × 5.00mm). No circuit modifications are required.

Q: What is the difference between the Cardinal CPPC7L-A7BP-125.0TS and CPPC7LZ-A7BP-125.0TS?

A: Both parts are electrically identical with the same maximum supply current (25mA), disable current (50µA), and frequency specifications. The difference lies in the part number designation (L versus LZ variant). Both are ROHS3 compliant and available in Tape & Reel packaging with similar inventory levels. Selection between them should be based on supplier availability and internal part numbering requirements.

Q: Which substitute offers the best power efficiency?

A: The Cardinal Components parts (CPPC7L-A7BP-125.0TS and CPPC7LZ-A7BP-125.0TS) offer the lowest disable current at 50µA, making them optimal for applications requiring extended periods in disabled mode. The Taitien OCETGLJTNF-125.000000 provides a balance with 10µA disable current and moderate 35mA supply current.

Q: Are there packaging format differences among the substitutes?

A: Yes. The Skyworks, Cardinal, and Taitien parts are supplied in Tape & Reel (TR) format, suitable for automated assembly. The Suntsu SXO75C3A481-125.000M is supplied in Bulk format. Tape & Reel packaging is standard for high-volume production; Bulk format may require manual handling or reeling for automated placement equipment.

Q: Do all substitutes meet current RoHS and REACH requirements?

A: All substitute parts are ROHS3 compliant. The original 7WA2572007 is RoHS compliant. All parts are REACH Unaffected or REACH Compliant, meeting current environmental and regulatory standards. All carry ECCN EAR99 classification and HTSUS code 8542.39.0001.

Q: What is the maximum seated height variation among substitutes?

A: Seated heights range from 1.42mm (original) to 1.90mm (Cardinal parts). The Taitien OCETGLJTNF-125.000000 at 1.50mm and Suntsu SXO75C3A481-125.000M at 1.60mm provide closer dimensional match to the original. Height variations of this magnitude typically do not affect PCB layout or component clearance in standard applications, but should be verified against specific board design constraints.

Q: Which substitute has the highest inventory availability?

A: The Suntsu Electronics SXO75C3A481-125.000M has the highest inventory at 3490 units. Among Tape & Reel packaged options, Cardinal Components CPPC7LZ-A7BP-125.0TS has 1133 units in stock.
