Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 132248 is determined by strict alignment of the following core parameters:

Primary Substitution Criteria:

• Connector Style: SMA (exact match required)
• Connector Type: Plug, Male Pin (exact match required)
• Impedance: 50 Ohms (exact match required)
• Contact Termination: Solder (exact match required)
• Shield Termination: Solder (exact match required)
• Mounting Type: Free Hanging (In-Line) (exact match required)
• Fastening Type: Threaded (exact match required)

Secondary Compatibility Factors:

• Frequency capability must meet or exceed 18 GHz
• Operating temperature range must encompass the application requirements
• Mating cycle rating must support the intended use case
• Cable group compatibility with RG-405 semi-rigid coaxial cable

Parts that deviate from these core parameters in contact termination method, shield termination method, or mounting configuration are classified as similar but not direct substitutes and require application-level verification before implementation.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Solder Shield Termination):

The TE Connectivity 1050735-1, Cinch 142-0693-051, Hirose HRM-101(09), and Hirose HRM-101S(09) maintain full electrical and mechanical compatibility with the Amphenol RF 132248 across all primary substitution criteria. These parts feature identical connector style, type, impedance, contact termination, shield termination, mounting type, and fastening type.

The Cinch 142-0693-051 offers extended frequency capability to 26.5 GHz and maintains the full operating temperature range of -65°C to 165°C, matching the Amphenol RF 132248 specification. This part is currently in active product status.

The Hirose HRM-101(09) and HRM-101S(09) provide increased mating cycle rating (1000 cycles versus 500 cycles) and maintain 18 GHz frequency capability. Both are in active product status. The HRM-101(09) features gold housing while HRM-101S(09) features silver housing. Operating temperature range is reduced to -55°C to 125°C.

The TE Connectivity 1050735-1 is marked as obsolete product status and should be avoided for new designs despite technical compatibility.

Partial Compatibility (Crimp Shield Termination):

The Hirose HRM-200-2-C(40) and HRM-200-2S-C(40) differ in shield termination method (crimp versus solder) and are not direct substitutes. These parts feature reduced frequency capability (1 GHz maximum) and narrower operating temperature range (-30°C to 85°C). Implementation requires application-level verification and assembly process modification.

Limited Compatibility (Frequency Constraint):

The Hirose HRM-100-1S1(40) maintains solder shield termination and RG-405 cable group compatibility but operates at maximum frequency of 12.4 GHz, below the 18 GHz specification of the Amphenol RF 132248. This part is suitable only for applications with frequency requirements not exceeding 12.4 GHz.

Compliance Status:

All recommended substitute parts maintain RoHS compliance. The Amphenol RF 132248, Cinch 142-0693-051, and Hirose HRM-200-2S-C(40) are ROHS3 compliant. All parts are REACH affected and carry EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1050735-1 be used as a replacement for the Amphenol RF 132248?

A: The TE Connectivity 1050735-1 meets all primary electrical and mechanical substitution criteria. However, this part is marked as obsolete product status. For new designs and long-term supply chain stability, the Cinch 142-0693-051 or Hirose HRM-101(09) are preferred alternatives in active product status.

Q: What is the difference between the Hirose HRM-101(09) and HRM-101S(09)?

A: Both parts are electrically and mechanically identical. The primary difference is housing color: HRM-101(09) features gold housing while HRM-101S(09) features silver housing. Both maintain 18 GHz frequency capability, solder shield termination, and 1000 mating cycles.

Q: Why are the Hirose HRM-200-2-C(40) and HRM-200-2S-C(40) listed as similar but not direct substitutes?

A: These parts employ crimp shield termination instead of solder shield termination, requiring different assembly processes. Additionally, maximum frequency is limited to 1 GHz, significantly below the 18 GHz capability of the Amphenol RF 132248. These parts are suitable only for low-frequency applications with crimp-compatible assembly methods.

Q: Does the Cinch 142-0693-051 offer any advantages over the Amphenol RF 132248?

A: The Cinch 142-0693-051 extends maximum frequency capability to 26.5 GHz while maintaining the full operating temperature range of -65°C to 165°C. It remains in active product status with 1131 units in stock. All other electrical and mechanical parameters are equivalent.

Q: What is the cable group compatibility requirement for substitution?

A: The Amphenol RF 132248 is specified for RG-405 semi-rigid coaxial cable (.085" to .086" diameter). Direct substitutes must support RG-405 cable group. The Hirose HRM-101(09) and HRM-101S(09) use RG-402 cable (.141" diameter), which is mechanically incompatible with RG-405 applications. The Hirose HRM-100-1S1(40) maintains RG-405 compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: No. The Amphenol RF 132248, Cinch 142-0693-051, and Hirose HRM-200-2S-C(40) are ROHS3 compliant. The TE Connectivity 1050735-1, Hirose HRM-100-1S1(40), HRM-101(09), HRM-101S(09), and HRM-200-2-C(40) are RoHS compliant but not specifically ROHS3 compliant. Verify compliance requirements for your application.

Q: What is the operating temperature limitation for the Hirose HRM-101 series?

A: The Hirose HRM-101(09) and HRM-101S(09) operate within -55°C to 125°C range, which is narrower than the Amphenol RF 132248 specification of -65°C to 165°C. These parts are not suitable for applications requiring operation below -55°C or above 125°C.

Q: How do mating cycle ratings affect part selection?

A: The Amphenol RF 132248 is rated for 500 mating cycles. The Hirose HRM-100-1S1(40), HRM-101(09), HRM-101S(09), HRM-200-2-C(40), and HRM-200-2S-C(40) are rated for 1000 mating cycles, providing extended connector life for high-cycle applications. The Cinch 142-0693-051 and TE Connectivity 1050735-1 maintain 500 mating cycles.

Q: Can the Hirose HRM-100-1S1(40) be used in 18 GHz applications?

A: No. The Hirose HRM-100-1S1(40) is specified for maximum frequency of 12.4 GHz. Applications requiring 18 GHz operation must use the Amphenol RF 132248, TE Connectivity 1050735-1, Cinch 142-0693-051, Hirose HRM-101(09), or Hirose HRM-101S(09).
