Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 3M 3462-0001 is determined by the following critical parameters:

• Connector Type & Configuration: Female card edge connector with dual-edge read capability
• Contact Pitch: 0.100" (2.54mm) spacing
• Termination Method: IDC (Insulation Displacement Contact)
• Mounting Style: Free hanging in-line configuration
• Contact Finish: Gold plating for signal integrity and corrosion resistance
• Operating Temperature Range: Minimum -55°C to 105°C
• Compliance: RoHS compliance for regulatory alignment

The CW Industries CWR-170-34-0021 qualifies as a substitute based on matching pitch, termination method, mounting type, contact finish, and compliance requirements. Position count variation (34 vs. 26) represents a functional upgrade path where the substitute accommodates higher-density applications while maintaining electrical and mechanical compatibility within the dual-edge card edge connector category.

Parameter Comparison

Engineering Selection Recommendations

The CW Industries CWR-170-34-0021 is an active product with ROHS3 compliance, providing a forward-compatible alternative to the obsolete 3M 3462-0001. The substitute maintains electrical and mechanical compatibility through identical pitch, dual-edge configuration, gold contact finish, and IDC termination. The extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) provides additional thermal margin for demanding applications. Position count increase (34 versus 26) accommodates higher-density signal routing without compromising connector footprint or pitch specifications.

Frequently Asked Questions (FAQ)

Q: Can the CWR-170-34-0021 directly replace the 3462-0001 in existing designs?

A: Yes, within the constraint that the PCB or card edge layout must accommodate the additional 8 positions. The connector maintains identical pitch, mounting style, and contact finish specifications.

Q: What is the significance of the position count difference?

A: The 34-position substitute provides additional contact capacity. Designs utilizing fewer than 26 positions can implement the substitute without modification. Designs requiring all 26 positions must verify that the additional 8 positions do not conflict with existing board layout.

Q: Are the contact materials compatible?

A: Both connectors feature gold-plated contacts with identical finish thickness (30.0µin). The 3462-0001 uses copper alloy base material while the CWR-170-34-0021 uses phosphor bronze. Both materials are suitable for IDC termination and provide equivalent electrical performance.

Q: Does the extended temperature range of the substitute affect compatibility?

A: No. The substitute's operating range (-55°C to 125°C) encompasses the original specification (-55°C to 105°C), ensuring compatibility across all original application conditions.

Q: What compliance considerations apply to this substitution?

A: Both parts meet RoHS requirements. The substitute carries ROHS3 compliance, representing current regulatory alignment. Both parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints for storage or handling.
