Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 225609-4 is determined by strict alignment with core electrical and mechanical parameters. The following criteria establish substitution validity:

Primary Substitution Criteria:

• Connector style must be SMA
• Connector type must be Plug, Male Pin
• Impedance must be 50 Ohms
• Mounting type must be Free Hanging (In-Line), Right Angle
• Maximum frequency must be 12.4 GHz or greater
• Operating temperature range must encompass -65°C to 165°C
• Fastening type must be Threaded
• Number of ports must be 1
• Dielectric material must be Polytetrafluoroethylene (PTFE)

The identified substitute part 142-0403-101 (Cinch Connectivity Solutions) meets all primary substitution criteria. The key distinction between the main part and substitute involves the contact termination method: the 225609-4 uses crimp termination, while the 142-0403-101 uses solder termination. Both termination methods are valid for SMA connector applications and do not affect electrical performance when properly executed.

Parameter Comparison

Engineering Selection Recommendations

225609-4 (TE Connectivity Aerospace, Defense and Marine):

• Primary selection for applications requiring crimp termination methodology
• Suitable for aerospace and defense applications where TE Connectivity qualification is specified
• RoHS non-compliant status requires consideration in regulated environments
• Beryllium copper center contact and stainless steel body provide specific material performance characteristics

142-0403-101 (Cinch Connectivity Solutions):

• Primary selection for applications requiring solder termination methodology
• ROHS3 compliant, suitable for applications with RoHS compliance requirements
• Specified mating cycle rating of 500 cycles provides documented mechanical durability
• Voltage rating of 250 V explicitly specified
• Brass body and center contact material provide alternative material composition
• Includes connector, end cap, and sleeve in package

Both parts maintain identical electrical performance at 50 ohms impedance and 12.4 GHz maximum frequency. Selection between these parts depends on termination method requirements, compliance certifications, and material specifications for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the 142-0403-101 directly replace the 225609-4 in existing designs?

A: Direct replacement is possible when the application design accommodates solder termination instead of crimp termination. Both connectors maintain identical SMA plug configuration, 50-ohm impedance, right-angle mounting, and frequency specifications. The termination method difference does not affect electrical performance when properly executed.

Q: What is the primary difference between these two connector models?

A: The primary difference is the contact termination method. The 225609-4 uses crimp termination, while the 142-0403-101 uses solder termination. Secondary differences include body material (stainless steel versus brass), center contact material (beryllium copper versus brass), and compliance certifications (RoHS non-compliant versus ROHS3 compliant).

Q: Are both connectors compatible with the same cable types?

A: Both connectors support RG-174, RG-188, and RG-316 cable groups. The 142-0403-101 additionally supports RG-161. Cable compatibility is maintained across both parts for standard applications.

Q: Which connector should be selected for RoHS-compliant applications?

A: The 142-0403-101 is ROHS3 compliant and is the appropriate selection for applications requiring RoHS compliance. The 225609-4 is RoHS non-compliant and is not suitable for regulated environments with RoHS requirements.

Q: What does the mating cycle specification mean?

A: The 142-0403-101 specifies 500 mating cycles, indicating the connector is rated for 500 connect-disconnect cycles. The 225609-4 does not provide a mating cycle specification. This parameter is relevant for applications involving frequent connector engagement and disengagement.

Q: Are the operating temperature ranges identical?

A: Yes, both connectors operate across the identical temperature range of -65°C to 165°C, ensuring thermal performance equivalence across standard industrial and aerospace applications.

Q: What is included in the 142-0403-101 package?

A: The 142-0403-101 package includes three components: one connector, one end cap, and one sleeve. The 225609-4 package contents are not specified.

Q: Can these connectors be used interchangeably in RF applications up to 12.4 GHz?

A: Yes, both connectors are rated for maximum frequency of 12.4 GHz and maintain 50-ohm impedance, supporting electrical interchangeability in RF applications within this frequency range when termination method compatibility is confirmed.
