3M 929870-01-24-10 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 3M 929870-01-24-10 is a 24-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications using through-hole solder termination. This connector features gold-plated mating contacts and tin-lead plated posts, with a push-pull fastening mechanism. The part is currently active in production with 1017 units in stock. Substitute parts may be required due to inventory constraints, application-specific performance requirements, or design revision needs.

Key Parameters

Substitute Part Grouping Explanation

The Mill-Max Manufacturing Corp. 310-13-124-41-001000 qualifies as a substitute based on the following critical parameters:

Matching Parameters:

• Connector type: Receptacle
• Number of positions: 24
• Pitch - mating: 0.100" (2.54mm)
• Style: Board to Board
• Mounting type: Through Hole
• Termination: Solder
• Fastening type: Push-Pull
• Contact finish - mating: Gold
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

Differing Parameters: The substitute part exhibits variations in contact type (female socket vs. forked), contact material (beryllium copper vs. copper alloy), contact finish thickness on mating surface (30.0µin vs. 10.0µin), insulation height (0.110" vs. 0.150"), operating temperature range (-55°C ~ 125°C vs. -40°C ~ 105°C), current rating (3A vs. 1A), voltage rating (100V, 150VDC vs. 1000V), and contact finish on posts (gold vs. tin-lead). These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active product status and comply with UL94 V-0 flammability requirements. The 3M 929870-01-24-10 is RoHS Compliant, while the Mill-Max 310-13-124-41-001000 is ROHS3 Compliant. Both parts are REACH-affected or unaffected respectively and carry EAR99 ECCN classification.

Selection between these parts depends on application voltage and current requirements. The 3M part supports 1000V operation with 1A current capacity, while the Mill-Max substitute is rated for 100V or 150VDC with 3A capacity. The Mill-Max part offers extended operating temperature range (-55°C ~ 125°C) compared to the 3M part (-40°C ~ 105°C). The thicker gold plating on the Mill-Max mating contacts (30.0µin vs. 10.0µin) may provide enhanced durability in high-cycle mating applications.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 310-13-124-41-001000 be used as a direct replacement for the 3M 929870-01-24-10?

A: Direct substitution is possible only if the application voltage requirement does not exceed 150VDC. The 3M part is rated for 1000V operation, while the Mill-Max substitute is limited to 100V or 150VDC. If the application requires 1000V operation, the Mill-Max part is not suitable.

Q: What are the key mechanical compatibility factors?

A: Both connectors share identical pitch (0.100"), position count (24), mounting type (through hole), and contact length (0.125"). The primary mechanical difference is insulation height: the 3M part measures 0.150" while the Mill-Max part measures 0.110". This difference may affect board layout and clearance considerations.

Q: How do the contact materials differ?

A: The 3M part uses copper alloy contacts with tin-lead plating on posts and gold plating on mating surfaces. The Mill-Max part uses beryllium copper contacts with gold plating on both mating surfaces and posts. Beryllium copper provides superior spring characteristics and contact retention.

Q: Are there temperature range considerations for substitution?

A: The Mill-Max part operates across a wider temperature range (-55°C ~ 125°C) compared to the 3M part (-40°C ~ 105°C). If the application requires operation below -40°C or above 105°C, the Mill-Max part may be suitable, provided voltage and current requirements are met.

Q: What is the significance of contact finish thickness differences?

A: The Mill-Max part features 30.0µin (0.76µm) gold plating on mating contacts versus 10.0µin (0.25µm) on the 3M part. Thicker plating generally provides improved corrosion resistance and extended contact life in high-cycle mating environments.

Q: Do both parts meet the same compliance standards?

A: Both parts achieve UL94 V-0 flammability rating and carry MSL 1 (Unlimited) moisture sensitivity classification. The 3M part is RoHS Compliant while the Mill-Max part is ROHS3 Compliant. Both carry EAR99 ECCN classification and share identical HTSUS code 8536.69.4040.
