3M 3575-0000 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The 3M 3575-0000 is a 20-position rectangular receptacle connector with IDC (Insulation Displacement Contact) termination, designed for discrete wire applications with 26-28 AWG wire gauge. This connector features gold-plated contacts, feed-through capability, and a 0.100" (2.54mm) pitch configuration across 2 rows.

The 3575-0000 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 3575-0000 is determined by the following critical parameters:

• Connector Type & Position Count: Must be a 20-position receptacle connector
• Pitch & Row Configuration: Must maintain 0.100" (2.54mm) pitch with 2-row layout and 0.100" row spacing
• Cable Termination Method: Must support IDC termination for discrete or ribbon cable applications
• Wire Gauge Compatibility: Must accommodate 26-28 AWG wire
• Contact Finish: Must provide gold or gold-based plating for electrical performance
• Mounting Configuration: Must support free-hanging, in-line mounting
• Feed-Through Capability: Must maintain feed-through contact design

The TE Connectivity AMP Connectors 1658623-4 meets all substitution criteria across these parameters.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658623-4 is the qualified substitute for the obsolete 3M 3575-0000. Both connectors share identical mechanical and electrical specifications across all critical parameters: 20-position configuration, 0.100" pitch, 2-row layout, IDC termination, 26-28 AWG wire compatibility, and feed-through design.

The TE Connectivity part offers additional advantages in terms of product lifecycle status. The 1658623-4 is classified as active, ensuring ongoing availability and supply chain support. The part is ROHS3 compliant and carries an MSL rating of 1 (Unlimited), indicating superior moisture handling characteristics compared to the obsolete 3M part.

Contact finish specifications are equivalent: both maintain 30.0µin (0.76µm) gold plating thickness. The TE Connectivity part offers flexibility with gold or gold-palladium finish options, both suitable for the same electrical performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1658623-4 directly replace the 3M 3575-0000 in existing designs?

A: Yes. Both connectors maintain identical pitch (0.100"), position count (20), row configuration (2 rows with 0.100" spacing), and IDC termination method. Mechanical and electrical compatibility is confirmed across all specified parameters.

Q: What is the difference between the contact types listed (Female Socket vs. Forked)?

A: Both contact types are female receptacle contacts designed for IDC termination. The contact geometry differences do not affect substitution eligibility, as both accommodate the same wire gauge (26-28 AWG) and termination method.

Q: Does the gold-palladium finish option on the TE Connectivity part affect compatibility?

A: No. The TE Connectivity 1658623-4 is available with either gold or gold-palladium finish, both at 30.0µin (0.76µm) thickness, matching the electrical and corrosion resistance requirements of the original 3M part.

Q: What is the significance of the RoHS3 compliance on the substitute part?

A: RoHS3 compliance indicates the TE Connectivity part meets current environmental and material restriction standards. This is relevant for new designs and applications subject to regulatory requirements. The obsolete 3M part does not carry this certification.

Q: Are there packaging differences between the two parts?

A: The 3M 3575-0000 packaging is not specified in available documentation. The TE Connectivity 1658623-4 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the MSL rating difference, and does it matter?

A: The 3M part lists MSL as Not Applicable. The TE Connectivity part carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. This provides greater flexibility in supply chain management for the substitute part.
