Substitute Part Grouping Explanation
Substitution eligibility for the TE Connectivity 5228435-1 is determined by strict equivalence across the following critical parameters:
Mandatory Matching Parameters:
- Connector Style: SMB
- Connector Type: Jack, Male Pin
- Impedance: 50 Ohms
- Mounting Type: Through Hole, Right Angle
- Contact Termination: Solder
- Shield Termination: Solder
- Fastening Type: Snap-On
- Frequency Maximum: 4 GHz
- Operating Temperature Range: -65°C to 165°C
- Mating Cycles: 500
- Number of Ports: 1
- Center Contact Material: Brass
- Center Contact Plating: Gold
All identified substitute parts meet these mandatory parameters. Variations in body material composition (brass versus zinc alloy), body finish (nickel versus tin), and dielectric material (polypropylene versus PTFE) do not preclude substitution when all electrical and mechanical interface specifications remain equivalent. Voltage rating variations and insertion loss specifications are noted where available but do not restrict substitution eligibility when the primary electrical characteristics align.

Engineering Selection Recommendations
Primary Recommendation: TE Connectivity 5415379-1
The 5415379-1 is the direct active equivalent from the original manufacturer. It maintains identical electrical specifications (50-ohm impedance, 4 GHz frequency rating, 335 V voltage rating, 0.6 dB insertion loss) and mechanical interface characteristics. The part carries RoHS Compliant certification and is currently in active production status with 965 units in stock. The substitution of zinc alloy body material and PTFE dielectric for the original brass body and polypropylene dielectric does not affect RF performance or mechanical compatibility.
Secondary Recommendations: Amphenol RF 903-373J-51A
The 903-373J-51A from Amphenol RF provides equivalent electrical and mechanical performance with ROHS3 Compliant certification. This part maintains the 0.6 dB insertion loss specification and brass body construction. Highest inventory availability (1536 units) supports supply chain continuity. Tin body finish differs from the original nickel finish but does not compromise electrical performance.
Tertiary Recommendations: Cinch Connectivity Solutions 131-1701-376 and 131-3701-306
Both Cinch parts maintain full electrical and mechanical equivalence with ROHS3 Compliant certification and active product status. The 131-1701-376 offers the highest inventory level (1288 units) among Cinch offerings. The 131-3701-306 provides brass body construction matching the original design. Both utilize PTFE dielectric material.
Alternative Options: Radiall USA R114665020, R114665020W, and R114665104
Radiall parts provide equivalent SMB jack configurations with ROHS3 Compliant certification and active status. These parts feature elevated voltage ratings (500 V versus 335 V original specification) and PTFE dielectric material. Insertion loss specifications are not provided for these alternatives.
All substitute parts maintain the mandatory electrical interface parameters and mechanical mounting characteristics required for direct PCB substitution.
Frequently Asked Questions (FAQ)
Q: Can the 5228435-1 be directly replaced with any of the listed substitute parts?
A: Yes. All listed substitute parts maintain identical SMB connector style, jack male pin configuration, 50-ohm impedance, through-hole right-angle solder mounting, and 4 GHz frequency rating. The electrical and mechanical interfaces are fully compatible for direct PCB substitution.
Q: What is the significance of the body material difference between brass and zinc alloy?
A: Body material composition does not affect RF electrical performance or mechanical interface compatibility. Both brass and zinc alloy bodies provide equivalent shielding and structural integrity for SMB connector applications. The choice between materials is driven by manufacturing process and cost considerations rather than functional requirements.
Q: Does the dielectric material change from polypropylene to PTFE affect performance?
A: No. Both polypropylene and PTFE dielectric materials are suitable for 50-ohm SMB connectors operating at 4 GHz. PTFE offers superior frequency stability and lower loss characteristics across extended frequency ranges, making it a preferred material in modern connector designs. The substitution represents a performance enhancement rather than a compromise.
Q: Why do some substitute parts have higher voltage ratings than the original?
A: Radiall parts (R114665020, R114665020W, R114665104) are rated for 500 V compared to the original 335 V specification. Higher voltage ratings indicate enhanced dielectric strength and do not restrict use in applications requiring only 335 V. These parts are fully compatible with the original design requirements.
Q: What is the difference between R114665020, R114665020W, and R114665104?
A: All three Radiall parts maintain identical electrical specifications and mechanical interfaces. The designations reflect internal manufacturing variations or packaging configurations. All three are functionally equivalent for SMB jack right-angle through-hole solder applications.
Q: Are all substitute parts RoHS compliant?
A: The original 5228435-1 carries RoHS Compliant certification. All active substitute parts carry either RoHS Compliant or ROHS3 Compliant certification, meeting current regulatory requirements for lead-free and restricted substance compliance.
Q: Which substitute part offers the best inventory availability?
A: The Amphenol RF 903-373J-51A provides the highest inventory level with 1536 units in stock, followed by the Cinch 131-1701-376 with 1288 units. The TE Connectivity 5415379-1 offers 965 units as the direct manufacturer equivalent.
Q: Can insertion loss specifications be used as a selection criterion?
A: Insertion loss is specified for the original 5228435-1 (0.6 dB) and the 5415379-1 and 903-373J-51A substitutes (both 0.6 dB). Other substitute parts do not provide insertion loss data. For applications where insertion loss is a critical parameter, selection should prioritize parts with specified values. Unspecified insertion loss does not indicate inadequate performance but rather reflects incomplete technical documentation.
Q: What is the significance of the MSL (Moisture Sensitivity Level) designation?
A: The original 5228435-1 and most substitute parts carry MSL 1 (Unlimited) designation, indicating no moisture sensitivity restrictions for storage or handling. Radiall parts carry "Not Applicable" MSL designation, reflecting their robust construction. Both designations are acceptable for standard PCB assembly processes.
