TE Connectivity 104655-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 104655-4 is a surface mount rectangular connector header with 30 positions arranged in 2 rows at 0.050" (1.27mm) pitch. This component is part of the AMPMODU 50/50 Grid series and features shrouded 4-wall construction with push-pull fastening. The connector is classified as Active product status and is widely used in automotive, medical, military, and telecommunications applications.

Substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for functionally equivalent components from different manufacturers that meet the same electrical and mechanical requirements.

Engineering Selection Recommendations

All listed Samtec substitute parts maintain Active product status and are fully compliant with RoHS3 and REACH regulations. The following selection criteria apply based on application requirements and manufacturing processes:

For Tube Packaging Applications: Select TFM-115-02-L-D, TFM-115-02-L-D-A, TFM-115-02-L-D-LC, TFM-115-02-S-D, or TFM-115-02-S-D-A-P when manual assembly or lower-volume production processes are employed. These parts maintain identical mechanical compatibility with the original TE Connectivity 104655-4.

For Tape & Reel Packaging Applications: Select TFC-115-02-F-D-A-K-TR, TFM-115-02-L-D-A-K-TR, TFM-115-02-L-D-K-TR, TFM-115-02-S-D-A-K-TR, or TFM-115-02-S-D-A-P-TR when automated pick-and-place assembly processes are required. These parts include Pick and Place features and are supplied in Tape & Reel format.

For Board Lock Feature Requirements: Select TFM-115-02-L-D-LC when mechanical board locking is specified in the design. This part includes the Board Lock feature matching the original component.

For Board Guide Feature Requirements: Select TFM-115-02-L-D-A, TFM-115-02-L-D-A-K-TR, TFM-115-02-S-D-A-K-TR, TFM-115-02-S-D-A-P, or TFM-115-02-S-D-A-P-TR when board guide alignment is required during assembly.

For Extended Temperature Range Applications: All Samtec substitutes operate across -55°C ~ 125°C, providing extended temperature coverage compared to the original part's -65°C ~ 105°C range. This extended range is suitable for applications requiring higher upper temperature limits.

For Higher Current Capacity Applications: Samtec TFC-115-02-F-D-A-K-TR provides 3.1A per contact, while TFM series parts provide 2.9A per contact, both exceeding the original 0.5A per contact rating. These higher current ratings are backward compatible for applications requiring increased current handling.

Contact Finish Considerations: The original part features Tin-Lead post finish. All Samtec substitutes use Tin post finish, which is acceptable for solder termination applications. Contact finish thickness variations (3.00µin to 30.0µin) do not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can Samtec TFM-115 series parts directly replace the TE Connectivity 104655-4?

A: Yes. All listed Samtec TFM-115 and TFC-115 parts are direct mechanical and electrical replacements. They maintain identical pitch (0.050"), position count (30), row configuration (2 rows), shrouding (4-wall), and termination method (solder). All parts are RoHS3 compliant and MSL 1 rated.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for manual assembly and lower-volume production. Tape & Reel (TR) packaging is used for automated pick-and-place assembly processes. Both packaging formats contain identical connector components; the difference is in presentation and handling method. Select based on your manufacturing process requirements.

Q: Are there differences in contact finish between the original and substitute parts?

A: The original TE Connectivity 104655-4 has Tin-Lead post finish with 30.0µin gold mating finish. Samtec substitutes use Tin post finish (RoHS compliant) with varying gold mating finish thicknesses (3.00µin to 30.0µin). These variations do not affect electrical or mechanical performance in solder termination applications.

Q: What does the "Board Lock" feature mean?

A: Board Lock is a mechanical feature that provides positive retention of the connector to the PCB after mating. The TFM-115-02-L-D-LC variant includes this feature. If your design requires board locking, select this specific part number.

Q: What does the "Board Guide" feature mean?

A: Board Guide is a mechanical alignment feature that assists in proper connector positioning during assembly. Parts with "-A" designation (such as TFM-115-02-L-D-A) include this feature. Select these variants if your assembly process requires alignment assistance.

Q: What does "Pick and Place" mean in the part designation?

A: Pick and Place refers to compatibility with automated assembly equipment. Parts with "-P" or "-K" designations in Tape & Reel format are optimized for automated pick-and-place machinery. Select these variants for high-volume automated assembly.

Q: Can I use a higher current-rated substitute in place of the original?

A: Yes. The original part is rated at 0.5A per contact. Samtec substitutes rated at 2.9A or 3.1A per contact are backward compatible and can be used in applications requiring the original 0.5A rating. Higher current capacity does not negatively affect lower-current applications.

Q: What is the operating temperature difference between the original and substitutes?

A: The original TE Connectivity 104655-4 operates from -65°C to 105°C. Samtec substitutes operate from -55°C to 125°C. The Samtec parts provide extended upper temperature capability (+20°C) but slightly reduced lower temperature capability (-10°C). Select based on your specific application temperature requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original part is RoHS Compliant. All Samtec substitute parts are ROHS3 Compliant, which is a more recent and stringent RoHS standard. ROHS3 compliance includes RoHS compliance.

Q: What is MSL 1 rating?

A: MSL (Moisture Sensitivity Level) 1 means Unlimited shelf life. Both the original part and all substitutes are MSL 1 rated, indicating no special moisture control or baking requirements before use.

Q: Can I mix and match different substitute part numbers in the same assembly?

A: All listed substitute parts are mechanically and electrically interchangeable. However, for consistency in manufacturing documentation, inventory management, and traceability, it is recommended to use a single part number per assembly design.

Q: What is the difference between TFM-115-02-S-D and TFM-115-02-L-D?

A: The "S" and "L" designations refer to different contact finish thicknesses. TFM-115-02-S-D has 30.0µin (0.76µm) gold mating finish, matching the original part. TFM-115-02-L-D has 15.0µin (0.38µm) gold mating finish. Both are functionally equivalent; select based on your specific finish thickness requirements.

Q: Is the circular contact shape of the original part critical?

A: The original TE Connectivity 104655-4 has circular contacts, while Samtec substitutes have square contacts. Both contact shapes are functionally equivalent for this connector type and provide identical electrical performance and mating characteristics. The square contact design is a standard alternative in the industry.
