Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 382437-3 is determined by the following critical parameters that must align across equivalent components:

Mandatory Matching Parameters:

• Type: SIP socket configuration
• Number of Positions: 3 (1 x 3) grid arrangement
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Contact Finish - Mating: Tin or Gold plating acceptable
• Contact Material - Mating: Phosphor Bronze or Beryllium Copper acceptable
• Contact Material - Post: Phosphor Bronze or Brass acceptable
• Housing Material: Thermoplastic or Polyamide (PA46) acceptable
• Termination Post Length: Minor variations within 0.005" tolerance acceptable

The Aries Electronics 03-0518-10 qualifies as a substitute based on these parameters, with the primary distinction being enhanced contact finish specifications and alternative material compositions that maintain functional equivalence.

Engineering Selection Recommendations

Primary Substitute: Aries Electronics 03-0518-10

The Aries Electronics 03-0518-10 serves as the qualified substitute for the obsolete TE Connectivity 382437-3. Selection of this substitute is supported by the following engineering factors:

Compliance and Certification Alignment: Both components maintain ROHS3 compliance and UL94 V-0 flammability ratings, ensuring regulatory and safety standard continuity. The Aries component carries REACH Unaffected status, providing additional environmental compliance documentation.

Product Status Advantage: The Aries Electronics 03-0518-10 maintains active product status with confirmed inventory availability (852 pieces), whereas the TE Connectivity component is obsolete. This status differential ensures long-term supply chain viability and continued manufacturer support.

Electrical and Mechanical Compatibility: Both components share identical pitch specifications (0.100" / 2.54mm), position configuration (3 x 1), and mounting methodology (through-hole solder termination). The post length variation of 0.005" (0.130" versus 0.125") falls within standard PCB design tolerances and does not compromise functional performance.

Contact Material Enhancement: The Aries substitute employs beryllium copper mating contacts with gold plating (10.0µin), providing superior corrosion resistance and contact reliability compared to the tin-plated phosphor bronze of the original component. The post-side brass construction with enhanced tin plating (200.0µin) maintains solderability while improving long-term reliability.

Housing Material Compatibility: Both components utilize glass-filled thermoplastic housing materials with equivalent mechanical and thermal properties. The polyamide (PA46) nylon 4/6 composition of the Aries component provides equivalent structural integrity and thermal performance within the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can the Aries Electronics 03-0518-10 be used as a direct replacement for the TE Connectivity 382437-3 in existing PCB designs?

A: Yes. Both components share identical pitch specifications (0.100" / 2.54mm), position count (3 x 1), and through-hole mounting footprints. The 0.005" post length difference does not affect PCB hole sizing or assembly compatibility. No PCB redesign is required.

Q: What is the significance of the contact finish difference between tin and gold plating?

A: The Aries substitute employs gold-plated beryllium copper mating contacts, which provide enhanced corrosion resistance and lower contact resistance compared to tin-plated phosphor bronze. This represents a performance improvement suitable for applications requiring extended service life or operation in corrosive environments.

Q: Are there any thermal performance differences between these components?

A: Both components are rated for identical operating temperature ranges (-55°C ~ 105°C for the TE Connectivity component; the Aries component does not specify a temperature range in the provided data). The glass-filled thermoplastic housing materials provide equivalent thermal stability within standard industrial operating conditions.

Q: Does the post length variation of 0.005" affect solder joint quality?

A: No. Standard PCB design practices accommodate post length variations within 0.010" tolerance. The 0.005" difference (0.130" versus 0.125") remains within acceptable manufacturing and assembly tolerances and does not compromise solder joint formation or mechanical strength.

Q: What is the current rating for the Aries substitute?

A: The Aries Electronics 03-0518-10 is rated for 3 amperes per contact. The TE Connectivity component does not specify a current rating in the provided data. Verify application current requirements against this 3-ampere specification.

Q: Are both components RoHS compliant?

A: Yes. Both the TE Connectivity 382437-3 and Aries Electronics 03-0518-10 are ROHS3 compliant. The Aries component additionally carries REACH Unaffected status, providing comprehensive environmental compliance documentation.

Q: What is the moisture sensitivity level for both components?

A: Both components are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard storage and handling procedures apply without special environmental controls.

Q: Why is the TE Connectivity component listed as obsolete?

A: The TE Connectivity 382437-3 is classified as obsolete by the manufacturer, indicating discontinued production and limited long-term availability. The Aries Electronics 03-0518-10 maintains active product status with ongoing manufacturer support and supply chain availability.
