Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 3M 3463-0002 is determined by the following critical parameters:

• 34-position configuration with dual-row layout
• 0.100" (2.54mm) pitch spacing
• Female gender with gold contact finish
• Panel mount with IDC termination
• Card thickness accommodation within specified range
• Operating temperature range coverage

The CW Industries CWR-171-34-0021 qualifies as a substitute based on matching these core electrical and mechanical parameters. Compatibility is established through identical position count, pitch, gender, termination method, and contact finish specification.

Parameter Comparison

Engineering Selection Recommendations

The CW Industries CWR-171-34-0021 serves as a functional substitute for the obsolete 3M 3463-0002 based on electrical and mechanical parameter alignment. The CW Industries part maintains all critical specifications including position count, pitch, contact configuration, and termination method.

Key considerations for selection:

• The CW Industries part is currently in active product status, ensuring ongoing availability and supply chain continuity.
• The CW Industries connector accommodates a wider card thickness range (0.032" ~ 0.070") compared to the 3M original (0.054" ~ 0.070"), providing greater design flexibility.
• Operating temperature range of the CW Industries part (-55°C ~ 125°C) exceeds the original specification, supporting extended environmental applications.
• The 3M part carries RoHS Compliant status, while the CW Industries part is RoHS non-compliant. Regulatory compliance requirements must be evaluated for the target application.

Frequently Asked Questions (FAQ)

Q: What makes the CW Industries CWR-171-34-0021 compatible with the 3M 3463-0002?

A: Both connectors share identical electrical and mechanical specifications: 34 positions, 0.100" pitch, female gender, dual-row configuration, gold contact finish, panel mount design, and IDC termination. These parameters define the functional interface and ensure mechanical and electrical compatibility.

Q: Are there differences in contact material between the two connectors?

A: Yes. The 3M 3463-0002 uses Copper Alloy contacts, while the CW Industries CWR-171-34-0021 uses Phosphor Bronze contacts. Both materials support gold plating at 30.0µin thickness and are suitable for the specified operating conditions.

Q: What is the significance of the wider card thickness range in the CW Industries part?

A: The CW Industries connector accepts cards from 0.032" to 0.070" thickness, while the 3M original accepts 0.054" to 0.070". The CW Industries range fully encompasses the original specification, allowing use with thinner card designs without compatibility loss.

Q: Does the higher operating temperature range of the CW Industries part affect substitution?

A: No. The CW Industries part operates from -55°C to 125°C, which exceeds the original -55°C to 105°C range. This extended capability does not compromise compatibility and may benefit applications requiring broader thermal performance.

Q: What compliance differences exist between these connectors?

A: The 3M 3463-0002 is RoHS Compliant, while the CW Industries CWR-171-34-0021 is RoHS non-compliant. Applications subject to RoHS regulations must account for this difference in material composition and regulatory status.

Q: Are the flange dimensions identical?

A: The flange features are functionally equivalent. Both use flush mount, top opening, unthreaded design. The 3M part specifies 0.125" (3.18mm) diameter, while the CW Industries part specifies 0.128" (3.25mm) diameter. This minor dimensional difference does not affect panel mount compatibility.
