TE Connectivity 2178712-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2178712-8 is an 8-position rectangular header connector from the Micro-MaTch series, designed for IDC (Insulation Displacement Connector) termination with ribbon cable applications. This component features a male pin contact type with 0.100" (2.54mm) pitch and dual-row configuration. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2178712-8 are identified based on strict electrical and mechanical parameter alignment within the Micro-MaTch rectangular connector series. The substitution criteria are:

Critical Matching Parameters:

• Number of Positions: 8
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.059" (1.50mm)
• Cable Termination: IDC
• Wire Type: Ribbon Cable
• Contact Finish: Tin
• Series: Micro-MaTch
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts identified (215083-8 and 7-215083-8) maintain all critical electrical and mechanical parameters. Both substitutes are active products from TE Connectivity AMP Connectors, ensuring ongoing availability and supply chain support. The primary functional difference is the connector type transition from header to plug configuration, which represents a complementary mating component rather than a direct form-factor replacement. Both substitutes support 28 AWG wire gauge specification and include feed-through features for ribbon cable applications.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The 2178712-8 header connector is classified as obsolete. Both substitute parts (215083-8 and 7-215083-8) are active products with confirmed ongoing availability. Selection between the two substitutes should be based on packaging and compliance documentation requirements:

215083-8 Selection Criteria:

• Packaging: Cut Tape (CT)
• Inventory: 6347 pieces available
• REACH Status: Vendor Undefined
• HTSUS Code: 8536.69.4051
• Suitable for standard procurement workflows

7-215083-8 Selection Criteria:

• Packaging: Cut Tape (CT)
• Inventory: 4550 pieces available
• REACH Status: REACH Unaffected
• HTSUS Code: 8536.69.8000
• Suitable for applications requiring explicit REACH compliance documentation

Both substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with existing assembly and storage protocols. The transition from header to plug connector type requires verification of mating interface compatibility within the target application circuit board or cable assembly design.

Frequently Asked Questions (FAQ)

Q: Can 215083-8 or 7-215083-8 directly replace the 2178712-8 in existing designs?

A: Both substitute parts maintain identical electrical and mechanical parameters (8 positions, 0.100" pitch, 2-row configuration, IDC termination, ribbon cable compatibility). However, the connector type changes from header to plug. Direct replacement requires that the mating interface in the application is designed to accept a plug connector rather than a header connector.

Q: What is the difference between 215083-8 and 7-215083-8?

A: Both parts are functionally identical in electrical and mechanical specifications. The primary differences are REACH compliance status (215083-8 is Vendor Undefined; 7-215083-8 is REACH Unaffected) and HTSUS classification codes. Selection depends on regulatory documentation requirements for the target application or region.

Q: Are the substitute parts compatible with the same ribbon cable specifications?

A: Yes. Both 215083-8 and 7-215083-8 support 28 AWG wire gauge and IDC termination with ribbon cable, matching the cable termination method of the original 2178712-8 part.

Q: What is the significance of the "Feed Through" feature listed for the substitute parts?

A: The feed-through feature indicates that the plug connector allows ribbon cable to pass through the connector body, enabling daisy-chain or multi-point connection configurations in ribbon cable harness designs.

Q: Are there packaging differences between the substitute parts?

A: Both substitute parts are supplied in Cut Tape (CT) packaging. The 2178712-8 original part packaging information was not specified in the available data.

Q: Do the substitute parts maintain the same RoHS and MSL compliance as the original part?

A: Yes. Both 215083-8 and 7-215083-8 are ROHS3 compliant with MSL 1 (Unlimited) rating, identical to the original 2178712-8 specifications.

Q: What mounting type differences exist between the main part and substitutes?

A: The 2178712-8 header supports both free hanging (in-line) and right-angle mounting. The substitute plug connectors (215083-8 and 7-215083-8) support free hanging (in-line) mounting only. Application designs requiring right-angle orientation require alternative component selection.
