Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A-2JA are identified based on the following core parameters that determine functional compatibility:

Primary Substitution Criteria:

• Impedance: 50 Ohms (mandatory match)
• Mounting Type: Surface Mount (mandatory match)
• Contact Termination: Solder (mandatory match)
• Shield Termination: Solder (mandatory match)
• Fastening Type: Snap-On (mandatory match)
• Number of Ports: 1 (mandatory match)
• RoHS Status: ROHS3 Compliant (mandatory match)

Secondary Variation Parameters:

• Connector Style: Alternative RF connector styles (AMMC, SWF, IPEX MHFIII)
• Connector Type: Jack/Receptacle and pin configuration variations
• Frequency - Max: Operating frequency range (3 GHz to 6 GHz)
• Operating Temperature: Temperature range variations
• Voltage Rating: Voltage capability differences
• Moisture Sensitivity Level: MSL rating variations

The identified substitutes maintain the core 50 Ohm impedance, surface mount solder termination, and snap-on fastening while offering alternative connector geometries and enhanced frequency performance.

Engineering Selection Recommendations

A-2JA (Amphenol RF) - Primary Selection

The A-2JA is the specified component and remains the primary choice for applications requiring AMMC jack configuration with male pin contact. This part offers the highest voltage rating (500 V) and unlimited moisture sensitivity handling (MSL 1). Active product status ensures continued availability and supply chain stability.

MM8130-2600RA2 (Murata Electronics) - Frequency-Enhanced Substitute

The MM8130-2600RA2 provides doubled frequency capability (6 GHz versus 3 GHz) while maintaining 50 Ohm impedance and surface mount solder termination. This substitute is suitable for applications requiring extended frequency performance. The SWF receptacle female socket configuration represents a different connector style. The voltage rating is reduced to 30 V, which may limit application scope. MSL 1 rating matches the primary part. Active product status confirms availability.

RECE.20369.001E.01 (Taoglas Limited) - Frequency-Enhanced Substitute

The RECE.20369.001E.01 offers 6 GHz frequency capability with IPEX MHFIII receptacle male pin configuration. Operating temperature range matches the primary part (-40°C to 90°C). This substitute maintains 50 Ohm impedance and solder termination. MSL 3 rating requires controlled storage conditions (168 hours maximum). Active product status confirms current availability.

Selection between substitutes depends on connector geometry compatibility with mating components, frequency requirements, voltage specifications, and moisture sensitivity handling capabilities.

Frequently Asked Questions (FAQ)

Q: Can the MM8130-2600RA2 directly replace the A-2JA in all applications?

A: The MM8130-2600RA2 maintains core RF specifications (50 Ohm impedance, surface mount solder termination, snap-on fastening) but differs in connector style (SWF receptacle female socket versus AMMC jack male pin) and voltage rating (30 V versus 500 V). Physical mating compatibility and voltage requirements must be evaluated for the specific application.

Q: What is the significance of the frequency difference between the A-2JA (3 GHz) and substitute parts (6 GHz)?

A: The A-2JA operates to 3 GHz maximum frequency. The MM8130-2600RA2 and RECE.20369.001E.01 both support 6 GHz operation. Substitutes with higher frequency ratings are backward compatible with lower frequency applications. Applications requiring frequencies above 3 GHz require the higher-rated substitutes.

Q: How does the voltage rating difference affect substitution?

A: The A-2JA is rated for 500 V, while the MM8130-2600RA2 is rated for 30 V. Applications requiring voltages above 30 V cannot use the MM8130-2600RA2. The RECE.20369.001E.01 voltage rating is not specified in available data. Voltage requirements must be confirmed before substitution.

Q: What does MSL 3 (168 Hours) on the RECE.20369.001E.01 mean compared to MSL 1 on the A-2JA?

A: MSL 1 (Unlimited) indicates the part can be stored indefinitely without moisture absorption concerns. MSL 3 (168 Hours) limits storage to 168 hours maximum after packaging opening before soldering. The RECE.20369.001E.01 requires controlled storage and handling procedures. The A-2JA and MM8130-2600RA2 offer more flexible storage conditions.

Q: Are all three parts ROHS3 compliant?

A: Yes. The A-2JA, MM8130-2600RA2, and RECE.20369.001E.01 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference between Jack and Receptacle connector types?

A: The A-2JA is a Jack with male pin (protruding contact). The MM8130-2600RA2 is a Receptacle with female socket (recessed contact). The RECE.20369.001E.01 is a Receptacle with male pin. Connector type determines mating compatibility with cable assemblies and mating connectors. Physical geometry must match the application interface.

Q: Can these parts be used interchangeably in PCB designs?

A: All three parts are surface mount components with snap-on fastening and solder termination. PCB footprint compatibility depends on specific connector dimensions and pin layouts. While electrical specifications align, physical mounting patterns may differ between AMMC, SWF, and IPEX MHFIII styles. PCB layout verification is required before substitution.
