3M 2326-5221-TG Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 2326-5221-TG is an active rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This 26-position, 2-row connector operates across -55°C to 105°C with a 3A current rating and UL94 V-0 flammability certification. The part is currently in active production status with 910 units in stock. Equivalent substitute parts are identified for applications requiring alternative sourcing, compliance upgrades, or extended temperature performance.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: connector type (header), contact type (male pin), number of positions (26), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (through hole, right angle), termination method (solder), fastening type (push-pull), contact finish on mating surface (gold), current rating (3A), flammability rating (UL94 V-0), and moisture sensitivity level (1 - Unlimited).

The identified substitute parts meet all these core electrical and mechanical parameters. Variations in secondary specifications such as contact material composition, insulation material type, contact finish thickness, and operating temperature range do not preclude substitution when the primary functional parameters align.

Engineering Selection Recommendations

All three parts maintain active production status and meet the core functional requirements for 26-position, 2.54mm pitch, right-angle header applications. The 3M 2326-5221-TG is RoHS non-compliant, while both TE Connectivity 1-87230-3 and Samtec TSW-113-25-G-D-RA are ROHS3 compliant. For applications subject to RoHS directives, the TE Connectivity or Samtec alternatives are required.

The TE Connectivity 1-87230-3 extends the lower operating temperature limit to -65°C compared to the 3M part's -55°C minimum. The Samtec TSW-113-25-G-D-RA provides the highest upper operating temperature at 125°C versus 105°C for the 3M part. Selection between substitute parts should be based on specific compliance requirements and thermal operating envelope constraints.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1-87230-3 be used as a direct replacement for 3M 2326-5221-TG?

A: Yes. Both parts share identical connector type, contact configuration, position count, pitch, row spacing, mounting orientation, termination method, and fastening mechanism. The TE Connectivity part is electrically and mechanically compatible for board-to-board and cable applications.

Q: What is the primary difference between the three parts?

A: The 3M 2326-5221-TG is RoHS non-compliant, while TE Connectivity 1-87230-3 and Samtec TSW-113-25-G-D-RA are both ROHS3 compliant. Operating temperature ranges differ: 3M operates -55°C to 105°C, TE Connectivity -65°C to 105°C, and Samtec -55°C to 125°C.

Q: Are there packaging differences between these parts?

A: The 3M part is supplied in standard packaging, while both TE Connectivity and Samtec alternatives are supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the Samtec TSW-113-25-G-D-RA have a specified current rating?

A: The Samtec part does not have a current rating specified in the available data. The 3M and TE Connectivity parts are both rated at 3A. Confirm current requirements with Samtec technical documentation if the 3A specification is critical to your application.

Q: Which substitute part should I select for RoHS-compliant applications?

A: Both TE Connectivity 1-87230-3 and Samtec TSW-113-25-G-D-RA are ROHS3 compliant. Selection between them depends on your specific operating temperature requirements and packaging preferences.
