Amphenol RF 000-35725-75 Coaxial Connector Equivalent & Substitute Parts

Part Overview

The Amphenol RF 000-35725-75 is an active, ROHS3-compliant coaxial connector plug designed for 75-ohm RF applications. This male pin connector features crimp termination for both center contact and shield, with a bayonet lock fastening mechanism suitable for free-hanging, in-line installations. The connector operates across a temperature range of -65°C to 165°C with a maximum frequency rating of 2 GHz and supports 500 mating cycles.

Identifying equivalent and substitute parts is necessary when the primary part is unavailable, when supply chain optimization is required, or when design flexibility permits the use of alternative connectors meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 000-35725-75 is permissible when an alternative connector maintains the following critical parameters:

• Impedance: 75 Ohms (mandatory for RF signal integrity)
• Connector Type: Plug, Male Pin (mechanical compatibility with mating receptacles)
• Mounting Configuration: Free Hanging or In-Line installation capability
• Termination Method: Crimp contact and shield termination
• Regulatory Compliance: ROHS3 compliance and EAR99 export classification
• Environmental Rating: Operating temperature range of -65°C to 165°C or broader
• Moisture Sensitivity: MSL 1 (Unlimited) classification

The substitute part TE Connectivity AMP Connectors 221629-5 shares the core electrical specification (75-ohm impedance) and connector type (male pin plug) with identical regulatory compliance status. However, differences exist in connector style (BNC versus standard), dielectric material composition, and contact finish specifications, which must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 000-35725-75 and TE Connectivity 221629-5 maintain active product status and full ROHS3 compliance with identical export classification (EAR99). Both connectors are rated for unlimited moisture sensitivity (MSL 1) and share the same HTSUS commodity code, indicating equivalent regulatory and trade classification.

Selection between these parts should be based on the following provided specifications:

• Connector Style Compatibility: The TE Connectivity part features BNC-style fastening, whereas the Amphenol part uses bayonet lock fastening. Verify mating receptacle compatibility before substitution.
• Dielectric Material: The Amphenol part uses PTFE dielectric, while the TE Connectivity part uses polyethylene. PTFE offers superior high-frequency performance and temperature stability; polyethylene is suitable for general RF applications.
• Contact Plating: The Amphenol part features silver plating on the center contact; the TE Connectivity part features gold plating. Both finishes provide adequate corrosion resistance and electrical conductivity for 75-ohm applications.
• Termination Specification: Verify that the TE Connectivity part supports crimp termination for both center contact and shield, as this specification is not explicitly provided in the substitute part data.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 221629-5 directly replace the Amphenol RF 000-35725-75 in all applications?

A: Direct replacement is permissible only when the mating receptacle is compatible with BNC-style fastening and when the polyethylene dielectric material meets application frequency and temperature requirements. The bayonet lock fastening mechanism of the Amphenol part differs from the BNC connector style of the TE Connectivity part, requiring verification of mechanical compatibility.

Q: What is the significance of the dielectric material difference between these connectors?

A: The Amphenol part uses PTFE (polytetrafluoroethylene), which provides superior electrical performance at higher frequencies and maintains stable dielectric properties across the full operating temperature range of -65°C to 165°C. The TE Connectivity part uses polyethylene, which is suitable for RF applications but exhibits different frequency and temperature characteristics. Selection depends on specific application frequency and thermal requirements.

Q: Are both connectors suitable for crimp termination?

A: The Amphenol RF 000-35725-75 explicitly specifies crimp termination for both center contact and shield. The TE Connectivity 221629-5 is described as a terminator plug connector; termination method details are not provided in the available specification data. Confirm termination compatibility with the TE Connectivity part before substitution.

Q: Do both connectors meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, classified under EAR99 export control, and assigned the identical HTSUS commodity code (8536.69.4010). Both maintain MSL 1 (Unlimited) moisture sensitivity rating. Regulatory substitution is permissible between these parts.

Q: What is the inventory availability for each part?

A: The Amphenol RF 000-35725-75 has 945 pieces in stock. The TE Connectivity 221629-5 has 1166 pieces in stock. Both parts are available as new original components.
