929647-03-24-EU Equivalent & Substitute Parts

Part Overview

The 929647-03-24-EU is a rectangular connector header manufactured by 3M, designed for through-hole board-to-board applications. This 24-position, single-row header operates at 0.100" (2.54mm) pitch and is rated for -40°C to 105°C operation. The part is currently active in production with 802 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 929647-03-24-EU is determined by the following critical parameters:

• Connector Type: Header, Breakaway configuration
• Contact Type: Male Pin
• Number of Positions: 24
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish - Mating: Gold
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: RoHS Compliant

The substitute part 0022284245 (Molex KK254 series) meets all critical substitution criteria. Both parts share identical position count, mating pitch, mounting method, and solder termination. Both employ gold-plated mating contacts and UL94 V-0 rated insulation materials. Both are RoHS compliant and rated for unlimited moisture sensitivity (MSL 1).

Parameter Comparison

Engineering Selection Recommendations

Both the 929647-03-24-EU and 0022284245 are active production parts with full regulatory compliance. The 3M part features a 2.5A current rating specification, while the Molex equivalent does not specify current rating in the provided data. The 3M connector uses PCT insulation material, whereas the Molex part employs glass-filled polyamide. Both parts meet UL94 V-0 flammability requirements and are RoHS compliant. The Molex part carries ROHS3 compliance designation, indicating alignment with the most current RoHS directive requirements. Contact finish thickness on the mating surface differs slightly (10.0µin versus 15.0µin), with the Molex part providing greater gold plating thickness. Post termination finish differs: the 3M part uses gold plating while the Molex part uses tin plating. Selection between these parts should be based on specific application requirements regarding current handling, insulation material compatibility, and termination finish specifications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022284245 directly replace the 3M 929647-03-24-EU in all applications?

A: Both parts share identical mating pitch (0.100"), position count (24), connector type (header breakaway), and mounting method (through-hole solder). Compatibility depends on application-specific requirements for current rating, insulation material, and termination finish. The 3M part specifies 2.5A current rating; the Molex part does not provide this specification. Verify current requirements against the 3M specification before substitution.

Q: What are the key differences between these two parts?

A: Primary differences include insulation material (PCT versus glass-filled polyamide), contact finish thickness on mating surfaces (10.0µin versus 15.0µin), and post termination finish (gold versus tin). The Molex part carries ROHS3 compliance versus RoHS compliance for the 3M part. Both meet UL94 V-0 flammability and MSL 1 moisture sensitivity requirements.

Q: Are both parts suitable for automotive and medical applications?

A: The Molex part lists automotive, general purpose, medical, and telecommunications applications. The 3M part does not specify applications in the provided data. Both parts meet UL94 V-0 and RoHS compliance requirements applicable to these industries. Application suitability should be confirmed against specific design requirements and industry standards.

Q: What is the significance of the different contact finish thicknesses?

A: The Molex part provides 15.0µin (0.38µm) gold plating on mating contacts compared to 10.0µin (0.25µm) on the 3M part. Greater plating thickness may provide enhanced durability in high-cycle mating applications, though both thicknesses meet standard connector specifications.

Q: Does the difference in post termination finish (gold versus tin) affect solderability?

A: The 3M part uses gold-plated posts while the Molex part uses tin-plated posts. Tin plating is standard for solder termination and provides excellent solderability. Gold plating on posts may affect solder wetting characteristics. Confirm soldering process compatibility with the selected termination finish.
