Key Parameters

Substitute Part Grouping Explanation

The Amphenol RF 930-110P-51A qualifies as a parametric equivalent to the 134102 based on matching electrical and mechanical specifications. Both connectors share identical core parameters that define functional compatibility: QMA connector style, male pin plug configuration, 50 Ohm impedance, solder contact termination, crimp shield termination, 6 GHz maximum frequency, snap-on fastening, and compatibility with the same cable group (RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907).

The substitution is valid across the following critical parameters:

• Connector Style: QMA
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Free Hanging (In-Line), Right Angle
• Contact Termination: Solder
• Shield Termination: Crimp
• Frequency - Max: 6 GHz
• Cable Group: Identical compatibility
• Fastening Type: Snap-On
• Center Contact Material: Brass
• Body Material: Brass
• Center Contact Plating: Gold
• Dielectric Material: PTFE
• Mating Cycles: 100
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)
• REACH Status: REACH Affected

The primary difference between these parts is packaging format (134102 supplied with end cap and ferrule versus 930-110P-51A in bulk packaging) and operating temperature range (134102: -40°C to 80°C versus 930-110P-51A: -65°C to 165°C).

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 134102 and 930-110P-51A are active products with ROHS3 compliance and REACH affected status, meeting current regulatory requirements for electronic component procurement. The 134102 is supplied with included accessories (end cap and ferrule), making it suitable for applications requiring pre-assembled components. The 930-110P-51A is available in bulk packaging, accommodating high-volume production environments where accessories are managed separately.

The 930-110P-51A operates across an extended temperature range (-65°C to 165°C) compared to the 134102 (-40°C to 80°C). Applications requiring operation outside the 134102 temperature specification should utilize the 930-110P-51A. The 930-110P-51A also includes a voltage rating specification of 480 V, which is not provided for the 134102.

Both connectors maintain identical electrical performance at 50 Ohm impedance and 6 GHz maximum frequency, ensuring functional interchangeability in RF circuit applications. Cable compatibility remains consistent across both parts for the specified RG-58 series and equivalent cable types.

Frequently Asked Questions (FAQ)

Q: Can the 930-110P-51A directly replace the 134102 in existing designs?

A: Yes, the 930-110P-51A is electrically and mechanically equivalent to the 134102 across all critical RF parameters including impedance, frequency response, connector style, and cable compatibility. The primary consideration is packaging: the 134102 includes an end cap and ferrule, while the 930-110P-51A is supplied in bulk format.

Q: What is the significance of the different operating temperature ranges?

A: The 134102 operates from -40°C to 80°C, while the 930-110P-51A operates from -65°C to 165°C. Applications requiring operation outside the 134102 temperature specification must use the 930-110P-51A. Within the overlapping temperature range (-40°C to 80°C), both connectors are functionally equivalent.

Q: Are both connectors RoHS and REACH compliant?

A: Yes, both the 134102 and 930-110P-51A are ROHS3 compliant and REACH affected, meeting current regulatory requirements for electronic component procurement and use in regulated markets.

Q: What cable types are compatible with both connectors?

A: Both connectors support identical cable group compatibility: RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. Cable selection is independent of which connector variant is used.

Q: Does the 930-110P-51A voltage rating of 480 V affect substitution decisions?

A: The 930-110P-51A includes a specified voltage rating of 480 V. The 134102 does not provide a voltage specification in the available data. For applications with defined voltage requirements, the 930-110P-51A voltage rating provides additional specification clarity.

Q: What is the difference in packaging between these two parts?

A: The 134102 is supplied with three pieces: one connector, one end cap, and one ferrule. The 930-110P-51A is supplied in bulk packaging without these accessories. Selection depends on whether pre-assembled components or bulk quantities are required for the application.

Q: Are the mating cycle ratings identical?

A: Yes, both connectors are rated for 100 mating cycles, providing equivalent mechanical durability and connection reliability.

Q: Can I use the 134102 in applications requiring the extended temperature range of the 930-110P-51A?

A: No, the 134102 is specified only for -40°C to 80°C operation. Applications requiring operation at temperatures below -40°C or above 80°C must use the 930-110P-51A with its -65°C to 165°C operating range.
