Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with ROHS3 environmental standards. The following guidance applies to component selection:

Primary Substitutes (Closest Mechanical Alignment):

Samtec TSW-113-07-F-D and Samtec TSW-113-07-G-D-001 provide the closest dimensional match to the TE 6-146261-3, with identical contact length specifications (0.230" mating, 0.100" post) and overall contact length (0.430"). Both parts feature phosphor bronze contacts with gold mating finish and operate across -55°C to 125°C, exceeding the original part's temperature range. These parts are available in high inventory quantities (6411 and 949 units respectively).

Molex 0879142616 offers equivalent contact length specifications (0.230" mating) with slightly extended post length (0.110") and operates across the full temperature range. This part is available in tray packaging with the highest inventory level (3245 units).

Secondary Substitutes (Acceptable Dimensional Variance):

Amphenol ICC 10076801-101-26LF maintains identical mating contact length (0.230") with slightly extended post length (0.098") and insulation height (0.112"). This part features phosphor bronze contacts and operates to 130°C. Current rating is specified at 3A per contact, matching the original part.

Harwin M20-9761342 provides cuttable header functionality with gold-finished brass contacts. Operating temperature extends to 105°C with 3A per contact current rating. Insulation height matches the original specification at 0.100".

Conditional Substitutes (Dimensional Deviations Requiring Verification):

Molex 0010897261 and 0010897262 feature extended contact lengths (0.240" mating, 0.107" post) and overall length (0.437"), representing approximately 0.027" increase in overall contact length. These parts are suitable where additional mating depth is acceptable.

3M 961226-6404-AR operates at reduced current rating (2A versus 3A) and lower maximum temperature (-25°C to 105°C). Contact length specifications differ (0.217" mating, 0.130" post). This part is suitable only for applications within its specified operating parameters.

Samtec MTSW-113-08-L-D-225 features extended post length (0.205") and overall contact length (0.530"), designed for applications requiring increased standoff height. Operating temperature range extends to 125°C with 3A current rating.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the TE Connectivity 6-146261-3?

A: Substitution compatibility is based on matching the core electrical and mechanical parameters: 26 positions in 2 rows, 0.100" (2.54mm) pitch spacing, male pin contacts, through-hole solder termination, push-pull fastening, and unshrouded design. All substitute parts listed maintain these specifications. Secondary parameters such as contact length, insulation material, and contact finish may vary within acceptable ranges for standard PCB applications.

Q: Can I use a substitute part with different contact length specifications?

A: Contact length variations affect mating depth and overall connector height. The TE 6-146261-3 specifies 0.230" mating contact length and 0.090" post length. Substitute parts with contact lengths within ±0.010" are generally compatible for standard board-to-board applications. Parts with significantly extended post lengths (such as Samtec MTSW-113-08-L-D-225 at 0.205") are suitable only where increased standoff height is required or acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed in this reference maintain ROHS3 compliance status. Amphenol ICC 10076801-101-26LF carries RoHS Compliant designation. All parts maintain MSL 1 (Unlimited) moisture sensitivity level, indicating no special storage or handling requirements.

Q: What is the difference between breakaway and cuttable header types?

A: Breakaway headers (TE 6-146261-3, Molex parts, Amphenol part) feature pre-scored sections allowing individual position removal. Cuttable headers (Harwin M20-9761342, Samtec MTSW-113-08-L-D-225) allow custom cutting to specific position counts. Both types maintain the same electrical and mechanical interface specifications for the full 26-position configuration.

Q: How do packaging formats affect part selection?

A: Packaging format (Bulk, Tray, Bag) affects handling, storage, and assembly processes but does not impact electrical or mechanical compatibility. The TE 6-146261-3 is supplied in Bulk packaging. Equivalent parts are available in Bulk, Tray, or Bag formats depending on manufacturer and inventory status. Selection should be based on assembly line requirements and inventory management practices.

Q: Which substitute parts offer the widest operating temperature range?

A: Samtec TSW-113-07-F-D, TSW-113-07-G-D-001, and TSW-113-07-G-D-005 operate across -55°C to 125°C, providing the widest temperature range. Samtec MTSW-113-08-L-D-225 also operates to 125°C. Amphenol ICC 10076801-101-26LF extends to 130°C. The original TE part operates to 105°C, so these substitutes provide extended thermal capability for demanding applications.

Q: What is the current rating difference between the TE part and substitute options?

A: The TE 6-146261-3 is rated at 3A. Amphenol ICC 10076801-101-26LF, Harwin M20-9761342, and Samtec MTSW-113-08-L-D-225 maintain 3A rating. The 3M 961226-6404-AR is rated at 2A, making it unsuitable for applications requiring full 3A current capacity. Molex parts do not specify current rating in available documentation.

Q: Are there differences in contact material between the main part and substitutes?

A: The TE 6-146261-3 uses copper alloy contacts. Substitute parts employ copper alloy, phosphor bronze, or brass contacts. Phosphor bronze (Amphenol, Samtec parts) and brass (Harwin) provide enhanced spring characteristics and durability. Copper alloy (Molex, 3M) maintains cost efficiency. All materials are suitable for standard PCB interconnection applications.

Q: Which substitute parts have the highest inventory availability?

A: Samtec TSW-113-07-F-D offers the highest inventory at 6411 units. Molex 0879142616 provides 3245 units in tray packaging. Molex 0010897262 offers 1865 units. Harwin M20-9761342 provides 2162 units. These parts are suitable for high-volume production requirements.
