Key Parameters

Substitute Part Grouping Explanation

Substitution of the K50-3C1E20.0000M is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 20 MHz
• Output Type: CMOS
• Package Type: 4-SMD, No Lead
• Package Dimensions: 7.00mm x 5.00mm
• Base Resonator: Crystal
• Type: XO (Standard)
• Function: Standby (Power Down)

Compatible Supply Voltage Range: The main part operates at 3.3V. Substitute parts must support 3.3V operation. Parts supporting multiple voltage levels (1.8V, 2.5V, 3.3V) are compatible, as they include 3.3V within their operating range.

Mechanical Compatibility: The 4-SMD, No Lead package with 7.00mm x 5.00mm footprint is the determining factor for PCB layout compatibility. Height variations within the seated maximum specification do not affect substitutability.

The KC7050Z20.0000C1KX00 meets all mandatory matching parameters and is classified as an Active product, making it a direct substitute for the Obsolete K50-3C1E20.0000M.

Parameter Comparison

Engineering Selection Recommendations

The KC7050Z20.0000C1KX00 is the recommended substitute for the Obsolete K50-3C1E20.0000M based on the following engineering criteria:

Product Status and Availability: The KC7050Z20.0000C1KX00 is classified as Active, ensuring ongoing availability and supply chain support. The main part K50-3C1E20.0000M is Obsolete, making substitution necessary for continued production.

Electrical Compatibility: Both parts are manufactured by KYOCERA AVX and share identical frequency (20 MHz), output type (CMOS), and standby power-down functionality. The substitute part supports 3.3V operation as required by the original design, with additional support for 1.8V and 2.5V operation.

Mechanical Compatibility: Both parts utilize the identical 4-SMD, No Lead package with 7.00mm x 5.00mm footprint, ensuring direct PCB layout compatibility without redesign.

Regulatory Compliance: Both parts are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited), meeting identical environmental and regulatory requirements.

Performance Characteristics: The substitute part demonstrates improved performance specifications: lower maximum supply current (7.3mA versus 10mA), lower disable current (5µA versus 10µA), and specified frequency stability (±20ppm). The extended operating temperature range (-40°C to 85°C versus -10°C to 70°C) provides additional design margin.

Frequently Asked Questions (FAQ)

Q: Can the KC7050Z20.0000C1KX00 be used as a direct replacement for the K50-3C1E20.0000M without PCB modifications?

A: Yes. Both parts share identical package type (4-SMD, No Lead), footprint dimensions (7.00mm x 5.00mm), and mounting type (Surface Mount). No PCB layout changes are required for substitution.

Q: What is the key difference between the main part and the substitute?

A: The primary difference is product status: the K50-3C1E20.0000M is Obsolete, while the KC7050Z20.0000C1KX00 is Active. The substitute also offers improved electrical performance (lower current consumption) and an extended operating temperature range.

Q: Does the substitute part support the 3.3V supply voltage required by the original design?

A: Yes. The KC7050Z20.0000C1KX00 supports 3.3V operation as part of its multi-voltage capability (1.8V, 2.5V, 3.3V). The original 3.3V supply voltage specification is fully compatible.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited). Regulatory and environmental compliance requirements are identical.

Q: What is the impact of the different operating temperature ranges?

A: The substitute part operates across -40°C to 85°C, compared to the main part's -10°C to 70°C range. This extended range provides additional design margin and is fully backward compatible with applications designed for the narrower temperature range.

Q: Is the frequency specification identical between both parts?

A: Yes. Both parts operate at 20 MHz with CMOS output and standby power-down functionality. The substitute part additionally specifies frequency stability at ±20ppm.

Q: What is the significance of the lower current consumption in the substitute part?

A: The KC7050Z20.0000C1KX00 draws 7.3mA maximum supply current and 5µA disable current, compared to 10mA and 10µA respectively for the main part. This represents improved power efficiency and reduced thermal dissipation in the substitute design.
