Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 8W50000002 are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

Electrical Compatibility Criteria:

• Frequency: 50 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Base Resonator: Crystal (exact match required)

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Size / Dimension: 0.098" L x 0.079" W / 2.50mm x 2.00mm (exact match required)

Regulatory Compliance:

• RoHS Status: ROHS3 Compliant (exact match required)
• ECCN: EAR99 (exact match required)
• HTSUS: 8542.39.0001 (exact match required)

The substitute parts identified meet all critical electrical and mechanical parameters. Variations in operating temperature range, supply current specifications, and packaging format (Bulk vs. Tape & Reel) do not affect functional substitution capability within the specified operating conditions of the main part.

Parameter Comparison

Engineering Selection Recommendations

All three parts—8W50000002 (TXC CORPORATION), SXO22C3A171-50.000M (Suntsu Electronics, Inc.), and ECS-2033-500-BN (ECS Inc.)—are Active products with ROHS3 compliance and EAR99 export classification. They meet identical electrical specifications for 50 MHz CMOS oscillator operation at 3.3V with Enable/Disable functionality and ±50ppm frequency stability.

Selection Considerations Based on Provided Data:

The ECS-2033-500-BN offers an extended operating temperature range of -40°C to 85°C compared to the -10°C to 70°C range of the 8W50000002 and SXO22C3A171-50.000M. This extended range is applicable for applications requiring operation at lower ambient temperatures or in thermally demanding environments within the specified limits.

The SXO22C3A171-50.000M and 8W50000002 share identical operating temperature specifications and seated height dimensions (0.90mm), providing direct mechanical and thermal compatibility.

All parts are available in Active status with ROHS3 compliance, REACH unaffected status (where specified), and identical ECCN and HTSUS classifications, confirming regulatory equivalence for procurement and deployment.

Frequently Asked Questions (FAQ)

Q: Can the SXO22C3A171-50.000M be used as a direct replacement for the 8W50000002?

A: Yes. Both parts share identical electrical specifications (50 MHz, CMOS output, 3.3V supply, Enable/Disable function, ±50ppm stability) and mechanical compatibility (4-SMD No Lead package, 2.50mm x 2.00mm footprint, Surface Mount). The primary difference is packaging format (Bulk vs. standard packaging) and supply current specification (15mA vs. not specified for the main part).

Q: What is the difference between the ECS-2033-500-BN and the 8W50000002?

A: The ECS-2033-500-BN operates across -40°C to 85°C, providing a wider temperature range than the 8W50000002 (-10°C to 70°C). Both parts are electrically identical at 50 MHz CMOS output with 3.3V supply and Enable/Disable function. The ECS-2033-500-BN is packaged in Tape & Reel format with higher inventory availability. Seated height is identical at 0.90mm.

Q: Are there any height differences that affect PCB layout?

A: The 8W50000002 and ECS-2033-500-BN both have a maximum seated height of 0.035" (0.90mm). The SXO22C3A171-50.000M has a maximum seated height of 0.039" (1.00mm), a 0.10mm difference. This minor variation does not affect standard PCB layout for surface mount assembly but should be verified if height clearance is critical in the application.

Q: Do all three parts have the same moisture sensitivity rating?

A: The 8W50000002 and ECS-2033-500-BN are both rated MSL 1 (Unlimited). The SXO22C3A171-50.000M does not specify an MSL rating in the provided data. MSL 1 indicates unlimited shelf life without moisture bake-out requirements.

Q: What is the supply current difference between these parts?

A: The SXO22C3A171-50.000M specifies 15mA maximum supply current. The ECS-2033-500-BN specifies 19mA maximum supply current. The 8W50000002 does not specify supply current in the provided data. Both specified values are within typical operating ranges for 50 MHz CMOS oscillators at 3.3V.

Q: Are all parts ROHS3 compliant?

A: Yes. All three parts—8W50000002, SXO22C3A171-50.000M, and ECS-2033-500-BN—are ROHS3 compliant and carry EAR99 export classification with HTSUS code 8542.39.0001.
