7XA2572002 XTAL OSC XO 125.0000MHZ CMOS SMD Equivalent & Substitute Parts

Part Overview

The 7XA2572002 is a 125 MHz crystal oscillator manufactured by TXC CORPORATION, designed for applications requiring a standard XO (Standard) CMOS output oscillator with Enable/Disable functionality. This surface mount device operates at 3.3V supply voltage with ±50ppm frequency stability across the -40°C to 85°C temperature range. The component is housed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a maximum seated height of 1.10mm.

The 7XA2572002 is currently in Active product status with 1122 pieces available in new original inventory. Identifying equivalent substitute parts is essential for supply chain continuity, design flexibility, and procurement optimization when the primary part becomes unavailable or when alternative sourcing is required.

• Identical planar dimensions (3.20mm x 2.50mm)
• Seated height difference of 0.10mm (1.10mm vs 1.20mm) is within standard PCB assembly tolerances and does not affect electrical performance or mechanical fit

Electrical Equivalence:

• All critical electrical parameters match exactly
• Frequency stability, operating temperature range, and output characteristics are identical
• Supply voltage and enable/disable functionality are identical

The SXO32C3A481-125.000M can be selected as a direct substitute when the 7XA2572002 is unavailable. Current inventory availability is significantly higher for the Suntsu part (5373 pieces vs 1122 pieces).

Frequently Asked Questions (FAQ)

Q: Can the SXO32C3A481-125.000M be used as a direct replacement for the 7XA2572002 in existing designs?

A: Yes. The SXO32C3A481-125.000M is a direct electrical and mechanical equivalent. All critical parameters including frequency, output type, supply voltage, enable/disable function, frequency stability, operating temperature range, package type, and physical dimensions are identical. No design modifications are required.

Q: What is the significance of the 0.10mm difference in seated height between the two parts?

A: The seated height difference (1.10mm for TXC vs 1.20mm for Suntsu) is within standard PCB assembly tolerances and does not affect electrical performance, mechanical fit, or board clearance in typical applications. Both parts use identical 4-SMD, No Lead packages with the same planar footprint.

Q: Are both parts RoHS compliant?

A: Yes. The 7XA2572002 is RoHS Compliant, and the SXO32C3A481-125.000M is ROHS3 Compliant. Both meet environmental compliance requirements.

Q: What are the key parameters that determine substitution eligibility for this oscillator?

A: Substitution eligibility is determined by exact matching of: frequency (125 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, frequency stability (±50ppm), operating temperature range (-40°C ~ 85°C), package type (4-SMD, No Lead), and physical dimensions (3.20mm x 2.50mm).

Q: Is the Suntsu part available in higher quantities?

A: Yes. The SXO32C3A481-125.000M has 5373 pieces in new original inventory compared to 1122 pieces for the 7XA2572002, providing better supply chain availability.

Q: Do both parts have the same moisture sensitivity level?

A: The 7XA2572002 specifies MSL 1 (Unlimited). The SXO32C3A481-125.000M does not provide MSL specification in the available data. Both parts are suitable for standard storage and handling conditions.

Q: What is the maximum supply current for these oscillators?

A: The 7XA2572002 does not specify maximum supply current in the available data. The SXO32C3A481-125.000M specifies 25mA maximum supply current. For applications requiring precise current specifications, consult the respective manufacturer datasheets.
