Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 901-155-16 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: SMA
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded
• Frequency - Max: 12.4 GHz
• Number of Ports: 1

Conditional Substitution Parameters:

• Contact Termination: Crimp (primary specification; solder termination represents functional alternative)
• Shield Termination: Crimp
• Operating Temperature Range: -65°C ~ 165°C (substitute must meet or exceed minimum and maximum limits)
• Voltage Rating: 375 V (substitute must meet or exceed)
• Mating Cycles: 500 (substitute must meet or exceed)
• Cable Group Compatibility: RG-174, 188, 188A, 316, LMR-100, M17/119-RG174

Compliance Parameters:

• RoHS Status: RoHS3 Compliant (preferred for new designs)
• REACH Status: REACH Affected (applicable to all identified substitutes)

Two substitute parts are identified based on these parameters. The first substitute (TE Connectivity AMP Connectors 1056443-1) offers solder termination as an alternative to crimp termination but operates within a reduced temperature range. The second substitute (TE Connectivity Aerospace, Defense and Marine 225532-4) maintains crimp termination and full temperature range compatibility while meeting military specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity Aerospace, Defense and Marine 225532-4

The 225532-4 is the preferred equivalent for direct replacement of the Amphenol RF 901-155-16. Both connectors maintain identical crimp termination specifications, matching impedance, frequency rating, and operating temperature range. The 225532-4 is actively manufactured and maintains full compatibility with cable groups RG-174, 188, and 316. This connector meets military specification MIL-PRF-39012 and is constructed from stainless steel with gold-plated brass contacts. The 225532-4 exhibits 0.3 dB insertion loss specification, providing measurable RF performance data. However, the 225532-4 carries RoHS non-compliant status, which may restrict use in applications requiring RoHS3 certification.

Secondary Substitute: TE Connectivity AMP Connectors 1056443-1

The 1056443-1 offers functional equivalence with a critical termination difference: solder termination replaces crimp termination. This connector maintains 50-ohm impedance, 12.4 GHz frequency rating, and threaded fastening. The 1056443-1 is currently obsolete and operates within a reduced temperature range of -40°C to 95°C, which does not meet the -65°C to 165°C specification of the primary part. The voltage rating of 250 V is also reduced compared to the 375 V specification of the 901-155-16. The 1056443-1 is RoHS compliant and suitable for applications where solder termination is preferred and temperature/voltage constraints are acceptable.

Compliance Considerations:

Applications requiring RoHS3 compliance should utilize the Amphenol RF 901-155-16 or identify alternative sources, as the identified substitutes present compliance limitations. The 225532-4 is RoHS non-compliant; the 1056443-1 is RoHS compliant but obsolete. For aerospace, defense, and marine applications, the 225532-4 provides military specification alignment.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 225532-4 directly replace the Amphenol RF 901-155-16 in all applications?

A: The 225532-4 provides direct functional replacement for applications where RoHS non-compliance is acceptable. Both connectors share identical crimp termination, 50-ohm impedance, 12.4 GHz frequency rating, and -65°C to 165°C operating temperature range. The primary distinction is RoHS compliance status and military specification alignment of the 225532-4.

Q: What is the primary difference between the 901-155-16 and the 1056443-1?

A: The primary difference is contact termination method. The 901-155-16 uses crimp termination; the 1056443-1 uses solder termination. Additionally, the 1056443-1 operates within a reduced temperature range (-40°C to 95°C) and lower voltage rating (250 V), and is currently obsolete.

Q: Are all three connectors compatible with RG-174 cable?

A: The Amphenol RF 901-155-16 and TE Connectivity ADM 225532-4 are both compatible with RG-174 cable. The TE Connectivity AMP 1056443-1 is compatible with RG-174 as well, though its cable group includes RG-179 and RG-187 as alternatives.

Q: What does "Free Hanging (In-Line)" mounting type mean?

A: Free Hanging (In-Line) indicates the connector is designed for direct cable termination without panel mounting or backshell attachment. The connector terminates the cable end directly and is secured through threaded mating with a corresponding receptacle.

Q: Why is the 225532-4 marked as RoHS non-compliant if it is actively manufactured?

A: Military and aerospace specifications, including MIL-PRF-39012 which the 225532-4 meets, may permit RoHS non-compliant materials for performance or reliability reasons. Applications requiring both military specification compliance and RoHS compliance require specific design review.

Q: What is the significance of the 0.3 dB insertion loss specification on the 225532-4?

A: Insertion loss of 0.3 dB quantifies the RF signal attenuation introduced by the connector at operating frequencies. This specification is provided for the 225532-4 but not specified for the 901-155-16 or 1056443-1, indicating measurable RF performance data availability for the military-grade connector.

Q: Can solder termination (1056443-1) be used instead of crimp termination (901-155-16)?

A: Solder termination represents a functional alternative to crimp termination. Selection depends on assembly process capability, reliability requirements, and application constraints. The 1056443-1 solder termination connector is obsolete and operates within reduced temperature and voltage specifications.

Q: What does "Mating Cycles: 500" indicate?

A: Mating cycles specify the number of times the connector can be mated and unmated while maintaining electrical and mechanical specifications. All three connectors are rated for 500 mating cycles, indicating equivalent durability in this parameter.

Q: Are there cable group differences that affect substitution?

A: The 901-155-16 supports RG-174, 188, 188A, 316, LMR-100, and M17/119-RG174. The 225532-4 supports RG-174, 188, and 316. The 1056443-1 supports RG-174, 179, 187, 188, and 316. Cable compatibility must be verified for specific applications; the 225532-4 does not support LMR-100 or M17/119-RG174.
