Substitute Part Grouping Explanation

Substitution logic for the TE Connectivity 221014-1 is based on the following critical parameters:

Primary Substitution Criteria (Exact Match Required):

Connector Style: SMB
Connector Type: Jack, Male Pin
Mounting Type: Through Hole, Right Angle
Contact Termination: Solder
Shield Termination: Solder
Fastening Type: Snap-On
Frequency - Max: 4 GHz
Operating Temperature: -65°C ~ 165°C
Number of Ports: 1

Secondary Substitution Criteria (Impedance-Dependent):

Impedance: 75 Ohms (primary specification) or 50 Ohms (application-dependent alternative)

Parts are grouped into two categories:

Group 1: Direct 75 Ohm Equivalents — Parts maintaining 75 ohms impedance with identical mechanical and electrical specifications. These provide direct functional replacement without circuit redesign.

Group 2: 50 Ohm Parametric Equivalents — Parts with 50 ohms impedance instead of 75 ohms. These are functionally compatible at the connector interface level but require circuit impedance matching verification for RF applications.

Engineering Selection Recommendations

For Direct Replacement (75 Ohm Impedance):

The TE Connectivity 5221014-1 and 5415895-1 are direct functional equivalents to the 221014-1. Both maintain 75 ohms impedance and through-hole right-angle solder mounting. The 5221014-1 is RoHS Compliant with identical dielectric material (Polypropylene). The 5415895-1 uses Polymethylpentene dielectric and offers higher inventory availability (1106 units). Both are active products with REACH Affected status.

The Samtec SMB7H-J-P-HN-RA-TH1 is a 75 ohm equivalent with PTFE dielectric material and ROHS3 Compliant status. This part offers the highest inventory availability (92700 units) and is suitable for applications requiring enhanced compliance certifications.

For 50 Ohm Applications:

The Cinch Connectivity 131-3701-306, Radiall 2010-7511-000, and Amphenol RF 903-373J-51A are 50 ohm parametric equivalents. All three are active products with ROHS3 Compliant and REACH Affected status. The Amphenol RF 903-373J-51A offers the highest inventory (1536 units) and uses PTFE dielectric with tin body finish.

The TE Connectivity 5228435-1 is a 50 ohm alternative but carries Obsolete product status and should not be selected for new designs.

Compliance Considerations:

The original 221014-1 is RoHS non-compliant. For applications requiring RoHS compliance, select from 5221014-1, 5415895-1, SMB7H-J-P-HN-RA-TH1, 131-3701-306, 2010-7511-000, or 903-373J-51A. All substitute options except 5228435-1 are REACH Affected.

Frequently Asked Questions (FAQ)

Q: Can the 50 ohm parts substitute for the 75 ohm 221014-1?

A: The 50 ohm parts (131-3701-306, 2010-7511-000, 903-373J-51A, 5228435-1) are mechanically and electrically compatible at the connector interface level. However, impedance mismatch affects RF circuit performance. Use 50 ohm parts only when the application circuit is designed for 50 ohm impedance. The 75 ohm parts (5221014-1, 5415895-1, SMB7H-J-P-HN-RA-TH1) are direct replacements without impedance considerations.

Q: What is the difference between the dielectric materials used?

A: The 221014-1 uses Polypropylene (PP) dielectric. Equivalent parts use PP, Polymethylpentene (PMP), or Polytetrafluoroethylene (PTFE). PTFE offers superior high-frequency performance and lower dielectric loss. PMP provides a middle ground between PP and PTFE. All materials are compatible with the specified operating temperature range of -65°C to 165°C.

Q: Why does the 5221014-1 show higher insertion loss (0.6 dB) than the 221014-1 (0.3 dB)?

A: Insertion loss variation reflects differences in manufacturing processes, material composition, or measurement conditions. Both values fall within acceptable ranges for SMB connectors at 4 GHz. The difference does not indicate functional incompatibility.

Q: Is the Samtec SMB7H-J-P-HN-RA-TH1 suitable for high-volume production?

A: Yes. The Samtec part offers the highest inventory availability (92700 units) among all listed equivalents and carries ROHS3 Compliant certification. It is an active product suitable for production applications.

Q: Should I use the obsolete 5228435-1?

A: No. The 5228435-1 carries Obsolete product status and should not be selected for new designs or production. Use active alternatives such as 903-373J-51A or 131-3701-306 for 50 ohm applications.

Q: Are all substitute parts rated for the same voltage and temperature range?

A: All listed parts operate across -65°C to 165°C. Voltage rating is 335 V for all parts except those where voltage rating is not specified in the data. Mating cycles are 500 for all parts with this specification provided.

Q: What is the difference between RoHS and ROHS3 compliance?

A: RoHS non-compliant parts (221014-1) do not meet Restriction of Hazardous Substances directives. RoHS Compliant parts (5221014-1, 5415895-1, 5228435-1) meet the original RoHS directive. ROHS3 Compliant parts (SMB7H-J-P-HN-RA-TH1, 131-3701-306, 2010-7511-000, 903-373J-51A) meet the updated RoHS 3 directive with additional substance restrictions.
