Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - TE Connectivity 5-104656-8

The 5-104656-8 is a direct equivalent to the 104656-8 with identical electrical and mechanical specifications. This part maintains all primary matching criteria including pitch, position count, row configuration, and contact rating. The primary distinction is RoHS3 compliance status and contact finish post material (Tin versus Tin-Lead). Both parts are active in production with comparable inventory levels. Selection of 5-104656-8 is appropriate for applications requiring RoHS3 compliance or when TE Connectivity supply chain continuity is prioritized.

Cross-Manufacturer Alternatives - Amphenol ICC 93289-140LF

The Amphenol ICC 93289-140LF (Rib-Cage™ III series) maintains all primary matching criteria with enhanced current rating of 1A per contact compared to 0.5A. This part features square contact geometry and thermoplastic glass-filled insulation material. Operating temperature range extends to 130°C maximum. This alternative is suitable for applications requiring higher current capacity or extended thermal performance within the specified parameter envelope. RoHS compliance is confirmed.

Cross-Manufacturer Alternatives - Samtec Tiger Eye™ TFM Series

The Samtec TFM-140-12-L-D-A, TFM-140-12-S-D-A, TFM-140-12-S-D-A-K, and TFM-140-12-S-D-LC maintain all primary matching criteria with significantly enhanced current rating of 2.9A per contact and voltage rating of 275VAC. These parts feature square contact geometry, LCP insulation material, and operating temperature range of -55°C to 125°C. Mating contact length is 0.139" (3.53mm) compared to 0.120" (3.05mm) on the primary part. All Samtec variants are ROHS3 compliant and active in production.

Differentiation among Samtec variants:

• TFM-140-12-L-D-A: Board to Board or Cable style with Board Guide feature
• TFM-140-12-S-D-A: Board to Board or Cable style with Board Guide feature
• TFM-140-12-S-D-A-K: Board to Board or Cable style with Board Guide and Pick and Place features
• TFM-140-12-S-D-LC: Board to Board or Cable style with Board Lock feature

Selection among Samtec variants depends on specific fastening and assembly requirements. All variants are suitable for applications requiring enhanced current capacity and voltage rating specifications.

Frequently Asked Questions (FAQ)

Q: Can the 5-104656-8 be used as a direct replacement for the 104656-8?

A: Yes. The 5-104656-8 is a direct equivalent with identical pitch, position count, row spacing, mounting type, and contact rating. The primary difference is RoHS3 compliance status. Both parts are electrically and mechanically interchangeable.

Q: What is the primary difference between the TE Connectivity parts and the Amphenol ICC 93289-140LF?

A: The 93289-140LF maintains all critical pitch and position specifications but features square contact geometry instead of circular, thermoplastic glass-filled insulation instead of LCP, and higher current rating of 1A per contact. Operating temperature maximum extends to 130°C. These differences do not preclude substitution when application requirements are within the specified ranges.

Q: Are the Samtec Tiger Eye™ TFM series parts compatible with the 104656-8?

A: The Samtec TFM series maintains all critical pitch, position, row spacing, and fastening specifications. However, these parts feature enhanced current rating (2.9A per contact), voltage rating (275VAC), and longer mating contact length (0.139" versus 0.120"). These enhancements make the Samtec parts suitable for higher-performance applications but require verification that the increased contact length does not create mechanical interference in the mating cavity.

Q: What does the contact finish thickness difference mean for substitution?

A: Contact finish thickness affects wear resistance and contact reliability over the connector lifecycle. The 104656-8 specifies 30.0µin (0.76µm) gold mating finish. The TFM-140-12-L-D-A specifies 15.0µin (0.38µm), while other Samtec variants specify 30.0µin (0.76µm). Thicker finishes provide extended contact life. Substitution is acceptable when application cycle life requirements are within the specified finish thickness performance envelope.

Q: Can I substitute a part with a higher current rating?

A: Yes. A substitute part with higher current rating per contact (such as the Amphenol 93289-140LF at 1A or Samtec TFM series at 2.9A) is acceptable for applications originally specified at 0.5A per contact. The higher rating provides design margin and does not create incompatibility. Verify that the substitute part's physical dimensions, particularly mating contact length and insulation height, do not create mechanical interference.

Q: What is the significance of the Board Lock versus Board Guide features?

A: Board Lock (104656-8, TFM-140-12-S-D-LC) provides mechanical retention through locking tabs that engage the mating connector. Board Guide (93289-140LF, TFM-140-12-L-D-A, TFM-140-12-S-D-A) provides alignment without positive locking. Pick and Place feature (TFM-140-12-S-D-A-K) facilitates automated assembly. Selection depends on application assembly method and retention requirements.

Q: Are all substitute parts RoHS compliant?

A: The 104656-8 is marked as "Not applicable" for RoHS status. The 5-104656-8 is ROHS3 compliant. The Amphenol 93289-140LF is RoHS compliant. All Samtec TFM variants are ROHS3 compliant. Verify RoHS compliance requirements for your specific application before selection.

Q: What is the difference between Tin-Lead and Tin contact finish on the post?

A: The 104656-8 specifies Tin-Lead post finish, while all substitute parts specify Tin post finish. Tin-Lead finishes are restricted under RoHS regulations in many jurisdictions. Tin finishes are RoHS-compliant alternatives. Both finishes are suitable for solder termination. Substitution is acceptable when RoHS compliance is required or when post finish material restrictions do not apply.

Q: Can I use the 93289-140LF in an application designed for the 104656-8?

A: The 93289-140LF is mechanically and electrically compatible for applications within its specified parameter ranges. Key considerations include: (1) mating contact length is 0.130" versus 0.120", which may affect cavity depth compatibility; (2) insulation material is thermoplastic glass-filled instead of LCP; (3) contact shape is square instead of circular; (4) current rating is 1A instead of 0.5A. Verify that these differences do not create mechanical or electrical incompatibility in your specific application.

Q: Which substitute part should I select for maximum performance?

A: The Samtec TFM-140-12-S-D-A-K provides the highest current rating (2.9A per contact), voltage rating (275VAC), and includes both Board Guide and Pick and Place features. This part is suitable for high-performance applications requiring enhanced electrical capacity and automated assembly compatibility. Verify that the 0.139" mating contact length does not create mechanical interference in your mating cavity design.
