Amphenol RF 901-103-11 SMA Connector Plug Equivalent & Substitute Parts

Part Overview

The Amphenol RF 901-103-11 is an SMA connector plug with male pin configuration, rated for 50 ohms impedance, and designed for free hanging (in-line) solder termination. This coaxial RF connector operates across a frequency range up to 12.4 GHz and is compatible with RG-55, RG-142, RG-223, and RG-400 cable groups.

The 901-103-11 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or field replacement requirements. Substitute parts must maintain electrical compatibility while accommodating differences in termination methods, body materials, and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 901-103-11 are grouped based on the following core electrical and mechanical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Connector style (SMA)
• Connector type (Plug, Male Pin)
• Impedance (50 Ohms)
• Mounting type (Free Hanging/In-Line)
• Fastening type (Threaded)
• Frequency rating (12.4 GHz maximum)
• Operating temperature range (-65°C to 165°C)
• Dielectric material (PTFE)

Secondary Variation Parameters:

• Contact termination method (Solder vs. Crimp)
• Shield termination method (Clamp vs. Crimp)
• Cable group compatibility
• Body material composition
• Product status and compliance certifications

The 901-103-11 has direct equivalents within the Amphenol RF product line and cross-manufacturer alternatives from TE Connectivity Aerospace, Defense and Marine. Substitution is permissible when the primary compatibility criteria are maintained, with engineering evaluation required for applications sensitive to termination method differences.

Parameter Comparison

Engineering Selection Recommendations

Direct Amphenol RF Equivalent:

The Amphenol RF 901-103 is the primary substitute for the obsolete 901-103-11. Both parts share identical electrical specifications, impedance, frequency rating, and operating temperature range. The 901-103 maintains solder termination and clamp shield termination consistent with the original design. The 901-103 is classified as active product status with ROHS3 compliance, providing improved supply chain availability and regulatory alignment compared to the obsolete 901-103-11.

TE Connectivity Cross-Manufacturer Alternatives:

The TE Connectivity Aerospace, Defense and Marine 225532 series (1-225532-0, 225532-1, 225532-3) provides functional equivalence with the following considerations:

• All three variants maintain 50 ohm impedance, 12.4 GHz frequency rating, and PTFE dielectric material
• Contact and shield termination employ crimp methodology rather than solder/clamp, requiring assembly process modification
• All variants are classified as active product status
• 225532-1 holds ROHS3 compliance certification
• 1-225532-0 and 225532-3 are RoHS non-compliant
• Cable group compatibility varies by variant: 1-225532-0 supports RG-55A and RG-223; 225532-1 supports RG-58A and RG-58C; 225532-3 supports RG-142, RG-142A, and RG-142B

Selection between TE Connectivity variants depends on cable group requirements for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 901-103 directly replace the 901-103-11 without design modification?

A: Yes. The 901-103 maintains identical electrical and mechanical specifications including impedance, frequency rating, operating temperature range, and termination methods. The primary difference is product status transition from obsolete to active, with updated ROHS3 compliance.

Q: What is the primary difference between the Amphenol RF 901-103 and the TE Connectivity 225532 series?

A: The primary difference is termination methodology. The 901-103 uses solder contact termination with clamp shield termination. The 225532 series uses crimp contact termination with crimp shield termination. Both maintain 50 ohm impedance and 12.4 GHz frequency rating. Crimp termination requires different assembly equipment and procedures compared to solder termination.

Q: Which TE Connectivity 225532 variant should be selected for RG-142 cable applications?

A: The 225532-3 is specified for RG-142, RG-142A, and RG-142B cable groups. This variant is active product status but RoHS non-compliant.

Q: Are there compliance differences between substitute options?

A: Yes. The 901-103 is ROHS3 compliant. The 225532-1 is ROHS3 compliant. The 1-225532-0 and 225532-3 are RoHS non-compliant. Compliance requirements depend on end-use application and regulatory jurisdiction.

Q: What packaging options are available for substitute parts?

A: The 901-103 is supplied in bulk packaging. The 225532 series variants (1-225532-0, 225532-1, 225532-3) are supplied in bulk packaging. The original 901-103-11 packaging specification was not provided in available documentation.

Q: Can the TE Connectivity parts be used interchangeably within the 225532 series?

A: No. While all three variants (1-225532-0, 225532-1, 225532-3) share identical electrical specifications and frequency rating, they are specified for different cable groups. Selection must be based on the cable group requirement for the specific application.

Q: What is the insertion loss specification for TE Connectivity 225532 series parts?

A: The TE Connectivity 225532 series specifies 0.3 dB insertion loss. The Amphenol RF 901-103-11 and 901-103 do not provide insertion loss specifications in available documentation.
