Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1088312-1 are qualified based on the following core parameters that determine functional compatibility:

Electrical Parameters:

• Connector style (SMA)
• Connector type (Plug, Male Pin)
• Impedance (50 Ohms)
• Frequency capability (minimum 6 GHz)
• Voltage rating (335 V minimum)

Mechanical Parameters:

• Mounting type (Free Hanging, Right Angle)
• Contact termination (Solder)
• Shield termination (Solder)
• Cable group compatibility (RG-405 .085" Semi Rigid)
• Fastening type (Threaded)
• Mating cycles (500 minimum)

Environmental Parameters:

• Operating temperature range (must accommodate -65°C ~ 125°C minimum)
• Dielectric material (PTFE)
• Moisture sensitivity level (1)

Substitute parts listed below meet or exceed these parameters. Parts with higher frequency ratings, extended temperature ranges, or improved compliance certifications are included as they maintain backward compatibility while offering enhanced performance or regulatory advantages.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Requirement:

Parts 2-1478906-0, 3-1478906-0, 1051120-1, and 901-9221-2A are classified as active products and are recommended for new designs and ongoing procurement. The original 1088312-1 and 1051114-1 are obsolete and should be replaced in active applications.

For RoHS Compliance:

All substitute parts (1051114-1, 2-1478906-0, 3-1478906-0, 1051120-1, and 901-9221-2A) are RoHS compliant or ROHS3 compliant. The original 1088312-1 has not applicable RoHS status.

For REACH Compliance:

Parts 1051114-1 and 901-9221-2A are REACH affected. Parts 2-1478906-0, 3-1478906-0, and 1051120-1 have vendor undefined REACH status. The original 1088312-1 has vendor undefined REACH status.

For Frequency Performance:

Parts 1051114-1, 1051120-1, and 901-9221-2A support 18 GHz maximum frequency, exceeding the original 6 GHz specification. Part 2-1478906-0 supports 12.4 GHz. Part 3-1478906-0 matches the original 6 GHz specification. Selection depends on system frequency requirements.

For Temperature Range:

Parts 1051114-1 and 901-9221-2A support -65°C ~ 165°C operating temperature, exceeding the original -65°C ~ 125°C range. Part 1051120-1 supports -65°C ~ 105°C, which is narrower than the original specification. Parts 2-1478906-0 and 3-1478906-0 have unspecified operating temperature ranges.

For Direct Replacement:

Part 3-1478906-0 provides the closest electrical and mechanical match to the original 1088312-1, with identical frequency rating (6 GHz), impedance (50 Ohms), and core specifications, while offering active product status and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher frequency rating than the original 1088312-1?

A: Yes. Parts rated for 12.4 GHz or 18 GHz are backward compatible with applications requiring 6 GHz operation. Higher frequency ratings indicate broader bandwidth capability and do not compromise performance at lower frequencies within the 50 ohm impedance specification.

Q: What is the difference between the two Greenpar series parts (2-1478906-0 and 3-1478906-0)?

A: Both are active Greenpar series products with identical core specifications. Part 2-1478906-0 supports 12.4 GHz maximum frequency with silver housing color and stainless steel body. Part 3-1478906-0 supports 6 GHz maximum frequency with gold housing color and brass body, matching the original 1088312-1 more closely.

Q: Are all substitute parts compatible with RG-405 semi-rigid cable?

A: Yes. All substitute parts are specified for RG-405 cable compatibility. Part 901-9221-2A additionally supports .086" diameter cable in addition to the standard .085" specification.

Q: What is the significance of the operating temperature range difference?

A: The original 1088312-1 operates from -65°C to 125°C. Substitute parts 1051114-1 and 901-9221-2A extend this to -65°C to 165°C, providing wider environmental tolerance. Part 1051120-1 is limited to -65°C to 105°C. Selection depends on application temperature requirements.

Q: Why is the 1051120-1 listed as a substitute if its temperature range is narrower?

A: The 1051120-1 meets all core electrical and mechanical parameters for functional substitution. Its narrower temperature range (-65°C to 105°C) is a limitation that must be evaluated against specific application requirements. For applications operating within this range, it remains a valid substitute with active product status and ROHS3 compliance.

Q: What does "Moisture Sensitivity Level 1 (Unlimited)" mean?

A: MSL 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All listed parts share this specification.

Q: Can I substitute the 1088312-1 with the Amphenol RF 901-9221-2A?

A: Yes. The 901-9221-2A is functionally compatible, offering active product status, ROHS3 compliance, 18 GHz frequency capability, and extended temperature range (-65°C to 165°C). It is manufactured by a different supplier (Amphenol RF) but maintains identical electrical and mechanical interface specifications.

Q: What does "Includes" mean in the part specifications?

A: This indicates the quantity and type of components included with each connector. The original 1088312-1 includes 2 pieces (1 connector, 1 end cap). Part 1051120-1 includes 3 pieces (1 connector, 1 contact, 1 end cap), providing an additional spare contact.

Q: Are there any packaging differences between substitute parts?

A: Part 901-9221-2A is specified as bulk packaging. Other parts do not specify packaging type. Packaging differences do not affect electrical or mechanical compatibility but may influence procurement and handling procedures.
