Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 737349-2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 25
• Compatible Shell Size: B
• Compatible D-Sub Size: 25pos and HD44pos
• Cable Exit Angle: 180°
• Shielding: Unshielded
• Accessory Type: Two Piece Backshell
• Material: Acrylonitrile Butadiene Styrene (ABS)
• Hardware: Assembly Hardware, Strain Relief
• Mating Screws: 4-40
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part 300X10209X from Amphenol CONEC meets all mandatory matching parameters. The primary difference is color specification (gray versus black) and product status (active versus obsolete). Both parts share identical electrical and mechanical compatibility characteristics for D-Sub connector backshell applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Amphenol CONEC 300X10209X

The Amphenol CONEC 300X10209X is a direct functional equivalent to the TE Connectivity 737349-2. All critical electrical and mechanical parameters align, including connector position count, shell size compatibility, cable exit angle, shielding configuration, material composition, and hardware specifications.

Compliance and Status Advantages:

The 300X10209X holds active product status, ensuring ongoing availability and manufacturer support. This part is ROHS3 compliant and REACH unaffected, providing regulatory compliance advantages over the obsolete 737349-2. Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Color Consideration:

The substitute part is specified in gray rather than black. This represents the only visual difference between the two backshells. Functional and mechanical compatibility remains unchanged. Design specifications requiring specific color coding should be evaluated against application requirements.

Inventory and Supply:

The 300X10209X is available in active inventory (941 pieces), supporting immediate procurement needs for applications currently utilizing the obsolete 737349-2.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol CONEC 300X10209X directly replace the TE Connectivity 737349-2 in existing designs?

A: Yes. Both parts are 25 position two piece backshells with identical shell size (B), D-Sub compatibility (25pos and HD44pos), 180° cable exit angle, unshielded design, ABS material composition, and 4-40 mating screws. Mechanical and electrical compatibility is complete.

Q: What is the significance of the color difference between black and gray?

A: Color is a visual specification only and does not affect electrical or mechanical function. The gray 300X10209X performs identically to the black 737349-2. Applications requiring specific color coding for identification or aesthetic purposes should evaluate this difference against design requirements.

Q: Why is the TE Connectivity 737349-2 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support for this part. The Amphenol CONEC 300X10209X, with active product status, provides a functionally equivalent alternative with ongoing manufacturer support.

Q: Are there any compliance differences between the two parts?

A: The 300X10209X provides enhanced compliance status. It is ROHS3 compliant and REACH unaffected, compared to the 737349-2 where RoHS status is not applicable and REACH status is vendor undefined. Both parts share identical ECCN and HTSUS classifications.

Q: What does MSL 1 (Unlimited) mean for these backshells?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. Both parts can be stored and handled without moisture control precautions, providing maximum flexibility in inventory management and logistics.

Q: Are the mating screws identical between both parts?

A: Yes. Both the 737349-2 and 300X10209X use 4-40 mating screws for assembly and connection, ensuring hardware compatibility.

Q: Can I use the 300X10209X with 25 position D-Sub connectors and HD44 position connectors?

A: Yes. The compatible D-Sub size specification for both parts is 25pos and HD44pos, confirming compatibility with both connector types.

Q: What is the cable type for these backshells?

A: Both parts are designed for round cable types with a 180° cable exit angle, supporting standard D-Sub connector cable configurations.
