Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-178238-2 is determined by strict equivalence across the following parameters: connector type (receptacle), number of positions (20), number of rows (2), mounting configuration (panel mount, through hole, right angle), termination method (solder), connector style (outer shroud contacts), flange feature (M2.6 housing/shell), contact finish (gold), and moisture sensitivity level (MSL 1).

The substitute parts identified maintain these core electrical and mechanical parameters. Variations in packaging format, product status, contact finish thickness, and feature sets (such as shielding or board lock presence) are secondary considerations that do not affect functional interchangeability in applications requiring the specified core parameters.

Parameter Comparison

Engineering Selection Recommendations

For applications currently utilizing the TE Connectivity 2-178238-2, the following selection criteria apply:

Direct TE Connectivity Replacement: The part 2-5178238-2 is the primary substitute from TE Connectivity AMP Connectors. This part maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. The packaging format differs (tray versus original packaging), but this does not affect functional performance.

Cross-Manufacturer Alternatives: The 3M parts 10220-55G3PL, N10220-5212PC, and N10220-52B2PC provide functional equivalence across all core parameters. These parts are manufactured by 3M under the 102 Mini D Ribbon (MDR) series and maintain the required 20-position, 2-row, right-angle solder receptacle configuration with M2.6 housing. All three 3M alternatives carry active product status and RoHS compliance.

Compliance Considerations: The original 2-178238-2 is RoHS non-compliant. All identified substitutes are RoHS compliant, supporting modern regulatory requirements. REACH status is vendor-defined for TE Connectivity parts and unaffected for 3M parts.

Feature Variations: The 3M alternatives include shielding features not present in the original part. The N10220-52B2PC and 10220-55G3PL additionally feature board lock functionality matching the original design. Contact finish thickness varies between the 3M 10220-55G3PL (8.00µin) and other alternatives (30.0µin), consistent with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 2-5178238-2 be used as a direct replacement for the 2-178238-2?

A: Yes. The 2-5178238-2 maintains identical electrical and mechanical specifications including 20 positions, 2 rows, right-angle solder termination, panel mount through-hole configuration, M2.6 housing, and gold contact finish. The primary difference is product status (active versus obsolete) and RoHS compliance. Packaging format differs but does not affect functional performance.

Q: What are the key differences between TE Connectivity and 3M substitute options?

A: Both TE Connectivity 2-5178238-2 and 3M alternatives (10220-55G3PL, N10220-5212PC, N10220-52B2PC) meet the core electrical and mechanical requirements. The 3M parts are manufactured under the 102 Mini D Ribbon (MDR) series and include shielding features. Contact finish thickness on the 3M 10220-55G3PL is 8.00µin compared to 30.0µin on other alternatives. All maintain the required 20-position, 2-row configuration with right-angle solder termination.

Q: Does packaging format affect connector performance?

A: No. Packaging format (tray, bulk, or box) is a logistics consideration and does not affect electrical or mechanical performance. Selection should be based on procurement and inventory management requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitutes (2-5178238-2, 10220-55G3PL, N10220-5212PC, N10220-52B2PC) are RoHS compliant. The original 2-178238-2 is RoHS non-compliant.

Q: What is the significance of the shielding feature on 3M alternatives?

A: The shielding feature on 3M parts 10220-55G3PL and N10220-52B2PC provides electromagnetic interference (EMI) protection. This is an additional feature not present in the original 2-178238-2 and does not prevent substitution in applications where shielding is not required.

Q: Which substitute part should be selected for new designs?

A: Selection depends on manufacturer preference and supply chain strategy. The 2-5178238-2 maintains TE Connectivity sourcing continuity. The 3M alternatives provide equivalent functionality with active product status. All parts meet core electrical and mechanical requirements and carry RoHS compliance suitable for current regulatory environments.
