Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2-173268-4 is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (4), pitch (0.098"/2.50mm), number of rows (1), mounting type (free hanging in-line), contact termination method (crimp), and moisture sensitivity level (MSL 1). All identified substitute parts maintain these core electrical and mechanical specifications, ensuring direct functional compatibility in applications originally designed for the 2-173268-4.

The two substitute parts identified are the TE Connectivity 1470222-4 (High Performance Interconnect series, active status) and the Molex 0511910400 (51191 series, active status). Both components satisfy all critical parameter requirements and are currently in active production, providing viable alternatives to the obsolete 2-173268-4.

Parameter Comparison

Engineering Selection Recommendations

The 2-173268-4 is classified as obsolete and no longer in active production. Both identified substitute parts are currently active and available in production quantities.

TE Connectivity 1470222-4 is a direct equivalent within the TE Connectivity product family, belonging to the High Performance Interconnect (HPI) series. This part maintains all critical electrical and mechanical parameters and carries RoHS Compliant certification. The thermoplastic insulation material and specified operating temperature range of -40°C to 105°C provide documented performance characteristics. This option is suitable for applications requiring continuity within the TE Connectivity connector ecosystem.

Molex 0511910400 is an active substitute from an alternative manufacturer, part of the 51191 series. This component satisfies all critical parameter requirements and carries ROHS3 Compliant certification with REACH Unaffected status. The polyamide (PA66) nylon 6/6 insulation material and identical operating temperature range of -40°C to 105°C ensure functional equivalence. This option provides cross-manufacturer compatibility and is available in bulk packaging with substantial inventory levels.

Both substitute parts are suitable for direct replacement based on electrical and mechanical compatibility. Selection between them should be based on supply chain preferences, existing connector ecosystem standardization, and compliance documentation requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 1470222-4 or 0511910400 be used as direct replacements for the 2-173268-4?

A: Yes. Both substitute parts maintain identical specifications for connector type, contact type, number of positions, pitch, number of rows, mounting type, contact termination, and moisture sensitivity level. These parameters define functional compatibility for rectangular connector housings in this category.

Q: What is the difference between the TE Connectivity 1470222-4 and Molex 0511910400?

A: Both parts are functionally equivalent across all critical parameters. The primary differences are manufacturer origin, insulation material composition (thermoplastic versus polyamide/nylon 6/6), and compliance certifications. The 1470222-4 is RoHS Compliant, while the 0511910400 is ROHS3 Compliant with REACH Unaffected status.

Q: Are contacts included with these substitute parts?

A: No. The 2-173268-4, 1470222-4, and 0511910400 are all connector housings supplied without contacts. Contacts must be sourced separately and crimped according to the connector specifications.

Q: What is the significance of the 0.098" (2.50mm) pitch specification?

A: Pitch defines the center-to-center distance between adjacent contact positions. The 0.098" (2.50mm) pitch is a critical parameter that determines physical and electrical compatibility. All substitute parts maintain this identical pitch, ensuring mechanical fit and electrical performance equivalence.

Q: Does the color difference between the 2-173268-4 (black) and 1470222-4 (ivory) affect compatibility?

A: Color is a cosmetic attribute that does not affect electrical or mechanical compatibility. The color difference reflects different product series within TE Connectivity but does not impact functional performance or interchangeability in circuit applications.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. MSL 1 (Unlimited) means the component has no moisture-related storage or handling restrictions and does not require special dry-pack storage conditions.

Q: Are there any temperature operating range differences between the substitute parts?

A: The 2-173268-4 does not specify an operating temperature range in the provided data. Both substitute parts specify -40°C to 105°C operating temperature range, which represents standard performance parameters for this connector category.
