Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 2-5178238-4

The 2-5178238-4 is the direct successor to the obsolete 2-178238-4. Both parts share identical series designation (CHAMP .050 II), electrical specifications, and mechanical configuration. The 2-5178238-4 carries Active product status and ROHS3 compliance, addressing regulatory requirements for new production and long-term system support. This part is the preferred selection for direct replacement applications.

Secondary Substitutes: 3M 10226-55G3PL, N10226-52B2PC, N10226-52B3PC

These 3M connectors from the 102 Mini D Ribbon (MDR) series maintain all core electrical and mechanical parameters. All three parts carry Active product status and RoHS compliance. The N10226-52B2PC and N10226-52B3PC variants include board lock features matching the original specification. These parts are suitable for applications where cross-manufacturer compatibility is acceptable.

Alternative Substitute: Hirose Electric Co Ltd DX10G1M-26SE(50)

The DX10G1M-26SE(50) is a Miniature High Density (HD) variant from the DXM series. This part maintains all core parameters and carries Active product status with ROHS3 compliance. Selection of this part is appropriate where miniature high-density connector specifications align with system requirements.

Note on N10226-5212PC

The N10226-5212PC lacks the board lock feature present in the original 2-178238-4 specification. This part is not recommended for applications where board lock functionality is required.

Frequently Asked Questions (FAQ)

Q: Can the 2-5178238-4 be used as a direct replacement for the obsolete 2-178238-4?

A: Yes. The 2-5178238-4 is the active production equivalent. Both parts share the CHAMP .050 II series designation and identical electrical and mechanical specifications. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between the TE Connectivity CHAMP .050 II series and the 3M 102 Mini D Ribbon (MDR) series?

A: Both series maintain the same 26-position, 2-row, right-angle solder receptacle configuration with outer shroud contacts and board lock features. The series designation reflects different manufacturer product lines. Electrical and mechanical compatibility is maintained across series for the specified parameters.

Q: Are there differences in contact finish thickness between substitute parts?

A: Yes. The original 2-178238-4 specifies 30.0µin (0.76µm) contact finish thickness. The 3M 10226-55G3PL specifies 8.00µin (0.203µm). Other substitutes specify 30.0µin (0.76µm) or do not specify thickness. Contact finish thickness does not affect substitution eligibility based on the core parameters provided.

Q: Does the Hirose DX10G1M-26SE(50) "Miniature High Density (HD)" designation affect compatibility?

A: The Miniature High Density (HD) designation indicates connector form factor classification. The DX10G1M-26SE(50) maintains all core electrical and mechanical parameters (26 positions, 2 rows, right-angle solder, panel mount, board lock, gold contact finish). This part is compatible with applications accepting the DXM series form factor.

Q: Which substitute parts include board lock features?

A: The following parts include board lock features matching the original specification: 2-5178238-4, 10226-55G3PL, DX10G1M-26SE(50), N10226-52B2PC, and N10226-52B3PC. The N10226-5212PC does not include board lock.

Q: What packaging formats are available for substitute parts?

A: Packaging varies by part number. The 2-5178238-4 is supplied in Tray format. The 10226-55G3PL is supplied in Bulk format. The N10226-5212PC, N10226-52B2PC, and N10226-52B3PC are supplied in Box format. The DX10G1M-26SE(50) is supplied in Tray format. Packaging selection does not affect electrical or mechanical compatibility.

Q: Are all substitute parts RoHS compliant?

A: The original 2-178238-4 is RoHS non-compliant. The 2-5178238-4 is ROHS3 compliant. The 3M parts (10226-55G3PL, N10226-5212PC, N10226-52B2PC, N10226-52B3PC) are RoHS compliant. The Hirose DX10G1M-26SE(50) is ROHS3 compliant. RoHS compliance status should be verified against specific regulatory requirements for your application.

Q: What is the moisture sensitivity level (MSL) for all parts?

A: All parts listed, including the original 2-178238-4 and all substitutes, carry MSL 1 (Unlimited) rating. This indicates no moisture sensitivity restrictions for storage or handling.
