8W50000010 XTAL OSC XO 50.0000MHZ CMOS SMD Equivalent & Substitute Parts

Part Overview

The TXC CORPORATION 8W50000010 is a 50 MHz crystal oscillator (XO) with CMOS output, designed for applications requiring a standard frequency reference with enable/disable functionality. This surface mount device operates at 3.3V supply voltage and is specified for industrial temperature ranges from -40°C to 85°C. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific packaging preferences while maintaining full electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 8W50000010 are qualified based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Frequency: 50 MHz (exact match required)
• Output: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 0.098" L x 0.079" W / 2.50mm x 2.00mm (exact match required)
• RoHS Status: RoHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All three substitute parts meet these critical parameters. Variations in maximum supply current, packaging format (Bulk vs. Tape & Reel), and seated height within tolerance do not affect functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified for direct replacement of the 8W50000010 based on matching electrical specifications, mechanical compatibility, and regulatory compliance status.

TXC 8W50000010 (Primary Part): Active production status with 746 units in stock. Bulk packaging format. Seated height 0.90mm. Recommended for continued use in existing designs.

Suntsu SXO22C3A481-50.000M: Active production status with 2999 units in stock. Bulk packaging format. Seated height 1.00mm (within tolerance). Supply current 15mA. Suitable for direct substitution with equivalent electrical performance.

Raltron CO2520-50.000-3.3-50-X-TR: Active production status with 4060 units in stock. Tape & Reel packaging format. Seated height 0.90mm. Supply current 4.5mA (lowest among alternatives). Recommended for high-volume production environments requiring automated assembly.

ECS Inc. ECS-2033-500-BN: Active production status with 181571 units in stock (highest availability). Tape & Reel packaging format. Seated height 0.90mm. Supply current 19mA. Recommended for applications with extended supply chain requirements or high-volume procurement.

All parts carry RoHS3 compliance, EAR99 export classification, and HTSUS code 8542.39.0001.

Frequently Asked Questions (FAQ)

Q: Can the Suntsu SXO22C3A481-50.000M be used as a direct replacement for the TXC 8W50000010?

A: Yes. Both parts share identical electrical specifications (50 MHz, CMOS output, 3.3V supply, ±50ppm stability, -40°C to 85°C operating range) and mechanical compatibility (4-SMD No Lead package, 2.50mm x 2.00mm footprint). The seated height difference of 0.10mm (1.00mm vs. 0.90mm) remains within standard PCB assembly tolerances.

Q: What is the difference between Bulk and Tape & Reel packaging formats?

A: Bulk packaging is suitable for manual assembly or small-volume production. Tape & Reel packaging is designed for automated pick-and-place assembly equipment and is standard for high-volume manufacturing. Both formats contain identical components; the difference is in delivery and handling method.

Q: Which substitute part has the lowest power consumption?

A: The Raltron CO2520-50.000-3.3-50-X-TR has the lowest maximum supply current at 4.5mA, compared to 15mA for Suntsu and 19mA for ECS Inc. This specification applies under normal operating conditions with enable function active.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts and the primary TXC 8W50000010 are RoHS3 compliant, meeting EU Directive 2011/65/EU requirements for restricted hazardous substances.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. These components do not require special dry-pack storage or baking procedures prior to assembly, simplifying inventory management and reducing handling costs.

Q: Can I mix different manufacturers' parts in the same production batch?

A: Yes. All substitute parts meet identical electrical and mechanical specifications. However, standard manufacturing practice recommends maintaining consistent sourcing within a single production lot to simplify traceability and quality documentation.

Q: What is the frequency stability specification ±50ppm?

A: Frequency stability ±50ppm means the actual oscillation frequency will not deviate more than 50 parts per million from the nominal 50 MHz specification across the operating temperature range (-40°C to 85°C). For a 50 MHz oscillator, this equals ±2.5 kHz maximum deviation.
