Substitute Part Grouping Explanation

Substitution of the 414305-1 is determined by strict equivalence across the following critical parameters:

Core Electrical Parameters:

Connector style (BNC)
Connector type (Jack, Female Socket)
Impedance (50 Ohms)
Frequency maximum (4 GHz)
Voltage rating (500 V)
Number of ports (1)

Core Mechanical Parameters:

Mounting type (Through Hole)
Contact termination (Solder)
Shield termination (Solder)
Fastening type (Bayonet Lock)

Environmental Parameters:

Operating temperature range compatibility
Mating cycles (500)

All substitute parts listed maintain these core parameters. Variations in materials (center contact material, body material, dielectric material) and finishes (body finish, center contact plating) are permitted provided they do not alter electrical performance or mechanical compatibility. Compliance certifications (RoHS, REACH) and product status (Active vs. Obsolete) are noted for procurement and regulatory considerations but do not disqualify functional equivalence.

Engineering Selection Recommendations

For New Designs and Procurement:

The 414305-1 is obsolete and should not be specified for new designs. Active substitute parts are available from TE Connectivity AMP Connectors across multiple product lines.

RoHS Compliance Consideration:

If RoHS3 compliance is required, select from the following active parts:

1-1337445-0 (TE Connectivity AMP, Greenpar series, extended temperature range -65°C to 165°C)
5221123-2 (TE Connectivity AMP, highest inventory availability at 3397 pcs)
5413969-2 (TE Connectivity AMP, highest inventory availability at 5912 pcs)
6274315-1 (TE Connectivity AMP)
031-5329-51RFX (Amphenol RF, extended temperature range -20°C to 165°C)

For Legacy System Support:

If RoHS non-compliance is acceptable or required for legacy compatibility:

221123-2 (TE Connectivity AMP, active status, 1077 pcs in stock)
227699-3 (TE Connectivity AMP, active status, 972 pcs in stock)
414460-1 (TE Connectivity AMP, active status, 934 pcs in stock)

Temperature Range Considerations:

The original 414305-1 operates from -55°C to 85°C. Most substitute parts maintain this range. For applications requiring extended temperature operation:

1-1337445-0 supports -65°C to 165°C
031-5329-51RFX supports -20°C to 165°C

Frequently Asked Questions (FAQ)

Q: Can I directly replace 414305-1 with any of the listed substitute parts?

A: Yes. All listed substitute parts maintain identical core electrical and mechanical parameters: BNC connector style, female socket jack type, 50 ohms impedance, through-hole solder termination, bayonet lock fastening, 4 GHz frequency rating, 500 V voltage rating, and 500 mating cycles. Physical PCB footprints are compatible.

Q: What is the difference between RoHS compliant and non-compliant versions?

A: RoHS compliance indicates the part meets Restriction of Hazardous Substances regulations. RoHS3 compliant parts (1-1337445-0, 5221123-2, 5413969-2, 6274315-1, 031-5329-51RFX) are suitable for applications subject to EU environmental regulations. RoHS non-compliant parts (221123-2, 227699-3, 414460-1) may be used in legacy systems or non-regulated applications.

Q: Does the material composition affect electrical performance?

A: Material variations (center contact material, body material, dielectric material, and finishes) do not alter the core electrical specifications. All parts maintain 50 ohms impedance, 4 GHz frequency rating, and 500 V voltage rating. Material selection may influence mechanical durability, corrosion resistance, and thermal performance in specific environments.

Q: Why does 1-1337445-0 have a different operating temperature range?

A: The 1-1337445-0 (Greenpar series) is designed for extended temperature operation (-65°C to 165°C) compared to the original 414305-1 (-55°C to 85°C). This part is suitable for applications requiring broader thermal performance while maintaining all other electrical and mechanical specifications.

Q: Is the Amphenol RF part 031-5329-51RFX a direct substitute?

A: Yes. The 031-5329-51RFX maintains all critical electrical and mechanical parameters. It is manufactured by Amphenol RF rather than TE Connectivity AMP. It features an extended operating temperature range (-20°C to 165°C) and includes specified insertion loss of 0.2 dB. It is RoHS3 compliant and REACH affected.

Q: What does "Greenpar series" mean for part 1-1337445-0?

A: Greenpar is a TE Connectivity product series designation. It indicates the part is designed with environmental and compliance considerations. The 1-1337445-0 is the only Greenpar series part in the substitute list and offers extended temperature range performance.

Q: How do I choose between multiple substitute parts with the same specifications?

A: Selection criteria include: (1) Product status (all listed substitutes are active), (2) RoHS compliance requirement, (3) Operating temperature range needed, (4) Inventory availability, (5) Manufacturer preference, and (6) Cost considerations. For standard applications within -55°C to 85°C, any listed part is functionally equivalent.

Q: Are there any insertion loss differences between substitute parts?

A: Only the Amphenol RF part 031-5329-51RFX specifies insertion loss at 0.2 dB. Other parts do not provide insertion loss specifications in the available data. For RF applications where insertion loss is critical, the 031-5329-51RFX provides documented performance.

Q: Can I use these parts interchangeably in existing PCB designs?

A: Yes. All substitute parts are through-hole solder mount BNC jacks with identical mechanical interfaces. PCB footprints and solder pad layouts are compatible. No PCB redesign is required.
