3M 929647-09-19-EU Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 929647-09-19-EU is an active rectangular connector header designed for through-hole board-to-board applications. This 19-position, single-row header operates at 0.100" (2.54mm) pitch and is rated for 2.5A continuous current with an operating temperature range of -40°C to 105°C. The connector features gold-plated copper alloy contacts, PCT insulation material, and UL94 V-0 flammability rating. Finding equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and optimize component sourcing across manufacturing environments.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 929647-09-19-EU and TE Connectivity 1-826629-9 maintain active product status and meet UL94 V-0 flammability requirements. The TE Connectivity substitute provides extended lower operating temperature capability (-65°C versus -40°C minimum) and higher current rating (5A versus 2.5A), offering additional design margin for applications requiring enhanced thermal or electrical performance. Both connectors are RoHS compliant and carry MSL 1 moisture sensitivity rating, indicating unlimited shelf life under standard storage conditions. The TE Connectivity part supports both board-to-board and cable interface styles, providing greater application flexibility compared to the 3M part's board-to-board specification. Contact material composition differs (brass versus copper alloy) and insulation material varies (PBT versus PCT), with both materials meeting the specified flammability standard. Selection between these parts should be based on specific application requirements regarding operating temperature range, current demands, and interface style compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-826629-9 directly replace the 3M 929647-09-19-EU in existing designs?

A: Direct substitution is supported for applications operating within the 3M part's specified temperature range (-40°C to 105°C) and current requirements (up to 2.5A). The TE Connectivity part's higher current rating (5A) and extended lower temperature range (-65°C) provide additional design margin. Physical pitch (0.100"), position count (19), and connector type (header, breakaway, male pin) are identical, ensuring mechanical and electrical compatibility at the mating interface.

Q: What are the key differences in contact materials between these parts?

A: The 3M 929647-09-19-EU uses copper alloy contacts with gold plating (10.0µin thickness on mating surface). The TE Connectivity 1-826629-9 uses brass contacts with gold plating on the mating surface (3.90µin thickness) and tin plating on the post (118.1µin thickness). Both contact finishes meet the connector's electrical and environmental requirements for this application category.

Q: How do the insulation materials differ, and does this affect substitution?

A: The 3M part uses PCT (Polycyclohexylenedimethylene Terephthalate) insulation, while the TE Connectivity part uses PBT (Polybutylene Terephthalate). Both materials achieve UL94 V-0 flammability rating and are suitable for the specified operating temperature range. Material selection does not restrict substitution for standard board-to-board applications.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS compliant and carry EAR99 export classification. The 3M part is RoHS Compliant, while the TE Connectivity part is ROHS3 Compliant. Both maintain MSL 1 moisture sensitivity rating and identical HTSUS classification (8536.69.4040), indicating equivalent regulatory standing for component sourcing and supply chain management.

Q: What is the significance of the TE Connectivity part supporting "Board to Board or Cable" style versus the 3M part's "Board to Board" specification?

A: The TE Connectivity part's expanded style designation indicates compatibility with both board-to-board and cable interface applications. The 3M part is specified for board-to-board use only. For applications requiring cable connectivity, the TE Connectivity substitute provides additional interface flexibility without requiring design modification.
