Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPD5713TK-A is determined by the following critical parameters:

Circuit Configuration: Both the main part and substitute must maintain SPDT topology to ensure functional equivalence in switching applications.

Impedance Matching: 50Ohm impedance is mandatory for RF circuit compatibility and signal integrity.

Frequency Coverage: The substitute must support the operational frequency range required by the application. The UPD5713TK-A operates from 50MHz to 2.5GHz; substitutes with extended frequency ranges (such as 50MHz to 3GHz) remain compatible for this application.

Package Compatibility: The 6-Minimold package format must be maintained to ensure mechanical and electrical compatibility with existing PCB layouts.

Supply Voltage Range: The substitute voltage range must encompass or overlap with the original 1.8V to 3.6V specification.

Environmental Specifications: Operating temperature range of -45°C to 85°C and MSL rating of 1 (Unlimited) establish baseline reliability requirements.

Regulatory Compliance: REACH Unaffected status ensures regulatory alignment.

The CG2214M6 meets all substitution criteria through equivalent circuit topology, impedance, package format, and environmental specifications, while offering improved electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the CG2214M6 directly replace the UPD5713TK-A in existing designs?

A: Yes. Both components share identical SPDT circuit topology, 50Ohm impedance, 6-Minimold package format, and overlapping supply voltage ranges. The CG2214M6 operates within the frequency range required by UPD5713TK-A applications and maintains equivalent environmental specifications.

Q: What are the key differences between these two parts?

A: The primary differences are product status (Obsolete vs. Active), frequency range (2.5GHz vs. 3GHz), insertion loss (0.95dB vs. 0.35dB), isolation (22.5dB vs. 23dB), and maximum supply voltage (3.6V vs. 5V). All differences favor the CG2214M6 or maintain compatibility.

Q: Are there packaging differences between UPD5713TK-A and CG2214M6?

A: Both components use the 6-Minimold package format. The UPD5713TK-A specifies flat leads, while the CG2214M6 is supplied in strip packaging. The physical package dimensions and pin configuration remain compatible for PCB assembly.

Q: Does the extended frequency range of CG2214M6 affect compatibility?

A: No. Extended frequency range represents additional capability. Applications operating at 2.5GHz or below remain fully compatible. The 50MHz lower frequency limit is identical in both components.

Q: What is the impact of improved insertion loss in the CG2214M6?

A: Reduced insertion loss (0.35dB vs. 0.95dB) decreases signal attenuation through the switch, improving overall system efficiency and signal integrity. This represents a performance improvement with no compatibility concerns.

Q: Are regulatory certifications equivalent between these parts?

A: Yes. Both components maintain REACH Unaffected status and identical Moisture Sensitivity Level ratings (1 - Unlimited), ensuring equivalent regulatory compliance and reliability classification.

Q: Can the CG2214M6 operate at the full 5V supply voltage in applications designed for 3.6V maximum?

A: Yes. The CG2214M6 is rated for 1.8V to 5V operation. Applications designed for 3.6V maximum supply voltage operate within the CG2214M6 specification envelope and require no modification.
