3M 3314-6305 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3314-6305 is a shrouded rectangular connector header designed for through-hole mounting with 14 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector features wire wrap termination, latch lock/eject hooks, and gold-plated mating contacts. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the 3M 3314-6305 is determined by strict equivalence in the following critical parameters:

Connector geometry: 14 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
Mounting and termination: Through-hole mounting with wire wrap termination
Shrouding configuration: Shrouded 4-wall design with keying slot
Fastening mechanism: Latch lock/eject hooks, long type
Electrical performance: 1A current rating, gold-plated mating contacts
Environmental compliance: UL94 V-0 flammability rating, RoHS compliance, MSL 1

The CW Industries CWN-572-14-0021 meets all critical substitution criteria. Variations in contact shape (circular vs. square), contact material (phosphor bronze vs. copper alloy), insulation material (thermoplastic vs. glass-filled polyester), and operating temperature ceiling (125°C vs. 105°C) do not preclude functional equivalence within the specified parameter set.

Engineering Selection Recommendations

The CW Industries CWN-572-14-0021 is an active product with current manufacturing support, whereas the 3M 3314-6305 is obsolete. Both parts meet UL94 V-0 flammability requirements and maintain MSL 1 moisture sensitivity classification. The CW Industries substitute provides ROHS3 compliance and an extended operating temperature range to 125°C, offering improved environmental margin compared to the original 3M specification. Both parts carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the CW Industries CWN-572-14-0021 be used as a direct replacement for the 3M 3314-6305?

A: Yes. Both connectors share identical pitch (0.100"), row count (2), position count (14), mounting method (through-hole), termination type (wire wrap), shrouding configuration (4-wall), and fastening mechanism (latch lock/eject hooks, long). Mating contact dimensions and gold plating thickness are identical.

Q: What are the differences between these two parts?

A: The CW Industries part features circular contact geometry versus the 3M square contacts, phosphor bronze contact material versus copper alloy, and thermoplastic insulation versus glass-filled polyester. The CW Industries part also specifies a higher operating temperature ceiling (125°C vs. 105°C) and includes nickel plating on the post contacts.

Q: Are there any compatibility concerns with PCB footprints?

A: No. Both connectors maintain identical pitch spacing (0.100" mating pitch, 0.100" row spacing), contact post length (0.610"), and insulation height (0.680" to 0.681"). PCB footprints designed for the 3M 3314-6305 will accommodate the CW Industries CWN-572-14-0021 without modification.

Q: Do both parts meet the same regulatory standards?

A: Both parts are UL94 V-0 rated and RoHS compliant. The CW Industries part carries ROHS3 certification, representing current compliance status. Both maintain MSL 1 classification and share identical ECCN (EAR99) and HTSUS (8536.69.4040) codes.

Q: What is the current availability status of each part?

A: The 3M 3314-6305 is obsolete with 782 pieces in stock. The CW Industries CWN-572-14-0021 is an active product with 949 pieces in stock and ongoing manufacturing support.
