Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 8Y50070001 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 50.0000 MHz (exact match required)
• Frequency Stability: ±10ppm (tolerance specification must be met or exceeded)
• Load Capacitance: 8pF (exact match required)
• Operating Mode: Fundamental (mode type must be identical)
• Operating Temperature Range: -20°C to 70°C (minimum coverage required)
• Package Type: 4-SMD, No Lead (physical and electrical interface must be compatible)
• Mounting Type: Surface Mount (assembly method must be compatible)

Compliance Parameters:

• RoHS Status: Compliant or higher standard required
• MSL Rating: 1 or equivalent (moisture sensitivity must be acceptable)

The substitute part Q 50,0-JXS11-8-10/10-FU-LF manufactured by Jauch Quartz meets all mandatory matching parameters and compliance requirements, establishing it as an electrical and mechanical equivalent within the specified design constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: 8Y50070001 (TXC CORPORATION)

The 8Y50070001 maintains active product status with RoHS compliance and REACH unaffected designation. This part is suitable for applications requiring the specified 50 MHz frequency with 8pF load capacitance and ±10ppm stability across the -20°C to 70°C operating window. The component carries MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling.

Substitute Part: Q 50,0-JXS11-8-10/10-FU-LF (Jauch Quartz)

The Jauch Quartz substitute maintains identical electrical specifications for frequency, stability, load capacitance, and operating mode. This part is also active product status with ROHS3 compliance and REACH unaffected designation. The substitute is available in Tape & Reel packaging format and carries the same MSL 1 rating.

Selection Basis:

Both parts satisfy all mandatory electrical and mechanical parameters required for 50 MHz crystal oscillator applications. Selection between these parts may be based on:

• Supply chain availability and lead time
• Packaging format requirements (bulk versus Tape & Reel)
• Inventory levels and procurement timing
• Established supplier relationships and qualification status
• ESR specification tolerance (80 Ohms versus 60 Ohms) where circuit design permits

Both parts maintain full compliance with RoHS and REACH regulatory requirements and are suitable for direct substitution within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can the Q 50,0-JXS11-8-10/10-FU-LF be used as a direct replacement for the 8Y50070001?

A: Yes. Both parts meet all mandatory electrical parameters: 50.0000 MHz frequency, ±10ppm stability, 8pF load capacitance, fundamental operating mode, and -20°C to 70°C temperature range. Both use identical 4-SMD no-lead package configuration and surface mount assembly method. Compliance ratings (RoHS and REACH) are equivalent or superior.

Q: What is the difference in ESR between these parts?

A: The 8Y50070001 specifies 80 Ohms ESR, while the Q 50,0-JXS11-8-10/10-FU-LF specifies 60 Ohms ESR. Both values fall within acceptable ranges for 50 MHz crystal oscillators. Circuit design must verify that the lower ESR of the substitute part does not introduce unintended effects in oscillator startup or frequency stability characteristics.

Q: Are the physical dimensions compatible?

A: Both parts use 4-SMD no-lead package configuration. The 8Y50070001 measures 0.079" L × 0.063" W (2.00mm × 1.60mm) with 0.022" maximum seated height. The substitute measures 0.063" L × 0.047" W (1.60mm × 1.20mm) with 0.016" maximum seated height. The substitute is physically smaller. PCB footprint design must accommodate the smaller dimensions of the substitute part.

Q: What packaging formats are available?

A: The 8Y50070001 is supplied in standard packaging format. The Q 50,0-JXS11-8-10/10-FU-LF is supplied in Tape & Reel (TR) format. Procurement and assembly processes must be compatible with the selected packaging format.

Q: Are both parts RoHS compliant?

A: Yes. The 8Y50070001 is RoHS compliant. The Q 50,0-JXS11-8-10/10-FU-LF is ROHS3 compliant, which represents a current or enhanced compliance standard. Both parts are REACH unaffected.

Q: What is the MSL rating and what does it mean?

A: Both parts carry MSL 1 (Unlimited) rating. This indicates no moisture sensitivity restrictions. The components do not require special moisture control during storage, handling, or assembly processes.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is established based on matching frequency, stability, load capacitance, and operating mode specifications. Physical interchangeability requires PCB footprint verification due to dimensional differences. Design validation should confirm that the lower ESR of the substitute part does not affect circuit performance.
