Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1814640-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 4 (2 x 2)
• Type: DIP, 0.3" (7.62mm) Row Spacing
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Contact Finish - Mating: Gold
• Contact Material - Mating: Beryllium Copper
• Mounting Type: Surface Mount
• Termination: Solder
• Operating Temperature Range: -55°C ~ 125°C
• Features: Open Frame

All four substitute parts from Mill-Max Manufacturing Corp. (110-43-304-41-105000, 110-93-304-41-105000, 114-43-304-41-117000, and 114-93-304-41-117000) meet these mandatory parameters. Variations exist in post contact finish material, post contact finish thickness, current rating, and regulatory compliance status, which are documented in the parameter comparison table below.

Engineering Selection Recommendations

For RoHS3 Compliant Applications:

Select either 110-43-304-41-105000 or 114-43-304-41-117000. Both parts are ROHS3 compliant and provide UL94 V-0 flammability certification. The 110-43-304-41-105000 features tin post contact finish, while 114-43-304-41-117000 also features tin post contact finish. Both deliver 3 A current rating with 10mOhm contact resistance specification.

For RoHS Non-Compliant or Legacy Applications:

Select either 110-93-304-41-105000 or 114-93-304-41-117000. Both parts feature tin-lead post contact finish and are RoHS non-compliant. These options are suitable for applications where RoHS compliance is not required. Current rating is 3 A for both parts.

General Substitution Considerations:

All substitute parts exceed the original 1 A current rating specification with 3 A capability, providing enhanced electrical performance margin. All substitute parts maintain the identical 0.100" (2.54mm) pitch and 4-position (2 x 2) DIP configuration with 0.3" (7.62mm) row spacing. All substitute parts are active products with confirmed inventory availability, eliminating obsolescence risk associated with the original TE Connectivity 1814640-2 part.

The primary differentiation between substitute options is regulatory compliance status (RoHS3 compliant versus non-compliant) and post contact finish material (tin versus tin-lead). Selection should be based on application regulatory requirements and PCB assembly process compatibility.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts mechanically compatible with the original TE Connectivity 1814640-2?

A: Yes. All four substitute parts maintain identical pitch specifications (0.100" mating and post), identical 4-position (2 x 2) DIP configuration, and identical 0.3" (7.62mm) row spacing. Surface mount termination and open frame design are consistent across all parts. Mechanical interchangeability is confirmed.

Q: What is the difference between the 110 series and 114 series Mill-Max parts?

A: The 110 series and 114 series are distinct product lines from Mill-Max Manufacturing Corp. Both series provide equivalent electrical and mechanical performance for this 4-position DIP socket application. Series designation reflects internal product categorization and does not affect functional compatibility. Selection between series may be based on inventory availability or internal design documentation requirements.

Q: Why do the substitute parts have higher current ratings (3 A) than the original part (1 A)?

A: The substitute parts are designed with enhanced electrical performance specifications. The 3 A current rating provides additional safety margin and performance headroom compared to the original 1 A specification. This higher rating does not create incompatibility; it represents improved capability that is backward compatible with applications designed for 1 A operation.

Q: What is the significance of the post contact finish difference (gold versus tin versus tin-lead)?

A: Post contact finish affects solder joint formation and long-term reliability in PCB assembly. The original part features gold post finish (5.00µin thickness). Substitute parts feature either tin or tin-lead post finish (200.0µin thickness). Tin and tin-lead finishes are standard for solder termination and provide reliable solder joint formation. The thicker finish on substitute parts (200.0µin versus 5.00µin) provides enhanced durability. Selection should align with PCB assembly process specifications and solder alloy compatibility.

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

A: For new product designs, select either 110-43-304-41-105000 or 114-43-304-41-117000, both of which are ROHS3 compliant and carry UL94 V-0 flammability certification. These parts meet current regulatory requirements for commercial and industrial applications. Both parts are active products with confirmed long-term availability.

Q: Are there any thermal or environmental performance differences between substitute options?

A: All substitute parts maintain the identical -55°C ~ 125°C operating temperature range as the original part. All parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity constraints. Environmental performance is equivalent across all substitute options.

Q: What is the impact of the mating contact finish thickness difference (5.00µin original versus 30.0µin substitutes)?

A: The substitute parts feature thicker gold plating on mating contacts (30.0µin versus 5.00µin). Thicker gold plating provides enhanced durability and extended contact life under repeated mating cycles. This represents improved performance and does not create incompatibility with existing IC packages or connector designs.

Q: Can the substitute parts be used in existing PCB designs without modification?

A: Yes. All substitute parts maintain identical pitch, position count, row spacing, and surface mount termination specifications. PCB footprints designed for the original TE Connectivity 1814640-2 are directly compatible with all four substitute parts. No PCB redesign or modification is required.
