Frequently Asked Questions (FAQ)

Q: Can I directly replace TE Connectivity 146220-7 with any of the listed substitute parts?

A: All listed substitute parts meet the critical electrical and mechanical parameters required for functional substitution. However, physical board layout verification is necessary due to minor variations in contact length and insulation height. The Amphenol ICC (FCI) BERGSTIK® II series (67996-134HLF, 67996-234HLF, 67997-134HLF, 67997-734HLF) and Samtec TSW-117-07-L-D are recommended as primary choices due to highest parameter alignment.

Q: What is the difference between the Amphenol ICC (FCI) parts 67996-134HLF and 67996-234HLF?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is the contact finish thickness on the mating surface: 67996-134HLF has 30.0µin (0.76µm) while 67996-234HLF has 15.0µin (0.38µm). Both exceed the original TE Connectivity specification of 5.00µin (0.127µm). Selection between these parts depends on application-specific contact wear requirements.

Q: Why does the Mill-Max 802-10-034-10-001000 have a circular contact shape instead of square?

A: The Mill-Max 802 series uses circular contact geometry as a design feature. While this part meets all critical electrical and mechanical parameters, the circular contact shape differs from the original square contact design. This variation requires design verification to confirm compatibility with mating connector receptacles.

Q: Are there any temperature range limitations I should consider?

A: The original TE Connectivity 146220-7 operates from -65°C to 105°C. Most substitute parts extend this range to -55°C or -65°C minimum and 125°C or 130°C maximum, providing improved thermal performance. The Molex 0010897340 and Mill-Max 802-10-034-10-001000 do not specify operating temperature ranges; design verification is required for temperature-critical applications.

Q: What packaging options are available for these substitute parts?

A: Substitute parts are available in multiple packaging formats: Bulk (Molex 0010897340, Amphenol ICC 67997-134HLF), Bag (Amphenol ICC 67996-134HLF, 67996-234HLF, 67997-734HLF, Samtec TSW-117-07-L-D), and Tube (Mill-Max 802-10-034-10-001000). Packaging selection depends on production volume and inventory management requirements.

Q: Which substitute part offers the best RoHS compliance status?

A: Molex 0010897340, Samtec TSW-117-07-L-D, and Mill-Max 802-10-034-10-001000 are ROHS3 compliant. Amphenol ICC (FCI) parts 67996-134HLF, 67996-234HLF, 67997-134HLF, and 67997-734HLF are RoHS compliant. The 3M 2334-6121-TG and original TE Connectivity 146220-7 are RoHS non-compliant. For new designs, ROHS3 or RoHS compliant parts are recommended.

Q: What is the current rating for each substitute part?

A: The original TE Connectivity 146220-7 has a current rating of 3A. Amphenol ICC (FCI) parts specify 3A per contact. The 3M 2334-6121-TG specifies 3A. Molex 0010897340, Mill-Max 802-10-034-10-001000, and Samtec TSW-117-07-L-D do not specify current ratings in the provided data; design verification is required for current-critical applications.

Q: Can I use these substitute parts in automotive or medical applications?

A: The Molex 0010897340 is specified for automotive, general purpose, lighting, medical, and telecommunications applications. Other substitute parts do not specify application categories in the provided data. Application suitability should be confirmed with the respective manufacturer for automotive or medical use cases.

Q: What contact material differences exist between the substitute parts?

A: The original TE Connectivity 146220-7 uses copper alloy contacts. Amphenol ICC (FCI) BERGSTIK® II series parts use phosphor bronze, which provides superior contact reliability and wear resistance. Samtec TSW-117-07-L-D uses phosphor bronze. Molex 0010897340 uses copper alloy. Mill-Max 802-10-034-10-001000 uses brass alloy. All materials are acceptable for general-purpose applications.

Q: Which substitute part has the highest inventory availability?

A: Samtec Inc. TSW-117-07-L-D has the highest inventory availability with 1280 units in stock, followed by Amphenol ICC (FCI) 67996-234HLF with 1152 units. These parts are recommended for applications requiring immediate availability.
