Molex 0022503085 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0022503085 is an 8-position rectangular receptacle connector with IDC (Insulation Displacement Contact) termination, designed for 24-26 AWG discrete wire applications. This connector features a 0.100" (2.54mm) pitch, tin contact finish, and feed-through capability in a single-row configuration. The product is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022503085 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Must be a receptacle with female socket contacts
• Position Count & Pitch: Must maintain 8 positions at 0.100" (2.54mm) pitch in a single-row layout
• Termination Method: Must support IDC (Insulation Displacement Contact) termination
• Wire Gauge Compatibility: Must accommodate 24-26 AWG wire or a subset thereof
• Contact Finish: Tin finish required for electrical and environmental performance consistency
• Mounting Configuration: Free hanging (in-line) mounting type
• Compliance Standards: ROHS3 compliance required

The TE Connectivity AMP Connectors part number 3-644564-8 qualifies as a substitute based on these parameters. While the substitute part specifies 26 AWG wire gauge (a subset of the original 24-26 AWG range), it maintains all other critical functional and electrical characteristics required for direct substitution in applications using 26 AWG wire.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 3-644564-8 is an active product with current manufacturing status, providing supply chain continuity for the obsolete Molex 0022503085. Both parts maintain ROHS3 compliance and identical electrical specifications for the core connector function.

Selection of the TE Connectivity substitute should be based on the following criteria:

• Wire Gauge Requirement: The substitute is specified for 26 AWG wire. Applications using 24 AWG wire with the original part require evaluation of the substitute's contact compression characteristics for 24 AWG compatibility, or wire gauge adjustment to 26 AWG.
• Mounting Configuration: The substitute supports both free hanging (in-line) and right-angle mounting options, providing additional design flexibility compared to the original part's free hanging configuration only.
• Fastening Type: The substitute includes a locking ramp fastening mechanism, which may affect mechanical integration in applications where the original part's fastening approach was specified.
• Contact Finish Thickness: The substitute specifies 80.0µin (2.03µm) tin finish compared to the original 100.0µin (2.54µm), remaining within acceptable ranges for IDC connector applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-644564-8 directly replace the Molex 0022503085 in all applications?

A: Direct replacement is applicable for applications using 26 AWG wire with IDC termination. Applications originally specified for 24 AWG wire require confirmation that the substitute's contact design accommodates 24 AWG wire gauge, or wire gauge standardization to 26 AWG.

Q: What is the primary difference between these two connector series?

A: The Molex 0022503085 belongs to the KK254/7720 series, while the TE Connectivity substitute is part of the MTA-100 series. Both series use identical 0.100" (2.54mm) pitch and IDC termination, but differ in manufacturing design and fastening mechanisms.

Q: Are there any compliance or environmental differences between these parts?

A: Both parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and EAR99 ECCN classification. No compliance or environmental performance differences exist between the two parts.

Q: Does the locking ramp fastening on the substitute affect compatibility?

A: The locking ramp is an additional feature on the substitute that does not prevent compatibility. However, mechanical integration points in the original design should be reviewed to ensure the fastening mechanism does not conflict with surrounding components or assembly procedures.

Q: What wire types are supported by the substitute part?

A: The TE Connectivity 3-644564-8 supports both discrete wire and ribbon cable termination via IDC, providing equivalent or expanded functionality compared to the original part's discrete wire specification.
