Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 382441-3 is determined by the following critical parameters that must align across candidate parts:

Mandatory Matching Parameters:

• Number of Positions: 7 (1 x 7) configuration
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Type: SIP socket connector

Compatible Variation Parameters:

• Contact Finish (Mating): Tin or Gold finishes are both acceptable for electrical compatibility
• Contact Material (Mating): Phosphor Bronze or Beryllium Copper provide equivalent performance
• Termination Method: Solder or Press-Fit termination types are functionally compatible
• Operating Temperature Range: Substitute parts with equal or extended temperature ranges are acceptable
• Housing Material: Thermoplastic or polyester-based materials are compatible

The Mill-Max Manufacturing Corp. 346-43-107-41-013000 meets all mandatory matching parameters and operates within compatible variation parameters, establishing it as a direct substitute for the obsolete TE Connectivity part.

Parameter Comparison

Engineering Selection Recommendations

The Mill-Max Manufacturing Corp. 346-43-107-41-013000 is a direct substitute for the obsolete TE Connectivity AMP Connectors 382441-3 based on the following engineering criteria:

Compliance and Regulatory Status: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with current manufacturing and environmental standards. The substitute part carries active product status, providing long-term availability and supply chain continuity compared to the obsolete main part.

Electrical and Mechanical Compatibility: The substitute part maintains identical pitch specifications (0.100" / 2.54mm) for both mating and post positions, ensuring direct mechanical compatibility with existing PCB layouts and mating connectors. The 7-position SIP configuration and through-hole mounting type are identical, eliminating the need for design modifications.

Performance Characteristics: The substitute part operates across an extended temperature range (-55°C ~ 125°C) compared to the main part (-55°C ~ 105°C), providing enhanced thermal performance for demanding applications. The gold contact finish on the mating side offers superior corrosion resistance and contact reliability compared to tin finish, while the beryllium copper contact material provides equivalent electrical performance to phosphor bronze.

Termination Consideration: The substitute part utilizes press-fit termination rather than solder termination. This represents a functional variation that requires PCB design accommodation through appropriately sized through-holes. Press-fit termination provides improved mechanical retention and eliminates solder joint reliability concerns in high-vibration environments.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 346-43-107-41-013000 be used as a direct replacement without PCB modifications?

A: The Mill-Max part maintains identical pitch and position count, allowing direct mechanical compatibility. However, the press-fit termination method requires PCB holes sized for press-fit insertion rather than solder-through holes. Verify PCB hole specifications before implementation.

Q: What is the difference between tin and gold contact finishes in this application?

A: Both finishes provide electrical conductivity suitable for signal and power applications. Gold finish offers superior corrosion resistance and lower contact resistance over extended service life. Tin finish is adequate for standard applications with moderate environmental exposure. The choice depends on application-specific reliability requirements.

Q: Are the contact materials (Phosphor Bronze vs. Beryllium Copper) functionally equivalent?

A: Both materials provide equivalent electrical conductivity and mechanical spring properties required for socket contact applications. Beryllium copper offers slightly superior spring characteristics and fatigue resistance. Both materials are suitable for the specified operating temperature range.

Q: Why is the termination post length different between the two parts?

A: The Mill-Max part features a longer termination post (0.175" vs. 0.130"), providing additional engagement depth in press-fit holes. This variation is compatible with standard PCB thickness specifications and improves mechanical retention in the press-fit application.

Q: Is the extended operating temperature range of the substitute part beneficial?

A: The substitute part's extended range (-55°C ~ 125°C vs. -55°C ~ 105°C) provides additional thermal margin for applications operating near temperature limits. This represents an enhancement with no negative impact on compatibility.

Q: What is the current rating of the substitute part?

A: The Mill-Max 346-43-107-41-013000 is rated for 3 amperes per contact. Verify this rating against application current requirements to ensure adequate capacity.

Q: Are both parts suitable for high-reliability applications?

A: Both parts maintain ROHS3 compliance and MSL 1 rating. The substitute part's active product status, extended temperature range, and gold contact finish provide enhanced reliability characteristics compared to the obsolete main part.
