TE Connectivity AMP Connectors 4-647050-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 4-647050-2 is a rectangular connector header designed for through-hole mounting applications. This connector features a 12-position, single-row configuration with 0.100" (2.54mm) pitch spacing and is classified as an obsolete product. The MTA-100 series connector is constructed with shrouded design, friction lock fastening, and tin-plated copper alloy contacts suitable for general-purpose applications operating between -55°C and 105°C.

Due to the obsolete product status of the 4-647050-2, equivalent substitute parts from active product lines are necessary to ensure continued component availability and supply chain continuity for new designs and production requirements.

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 4-647050-2 are identified based on strict equivalence of core electrical and mechanical parameters. The following parameters determine substitution eligibility:

Primary Matching Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 12
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock
• Contact Shape: Square
• Insulation Color: Black

Secondary Compatibility Parameters:

• Overall Contact Length: Within acceptable tolerance range
• Insulation Height: Within acceptable tolerance range
• Contact Length - Mating: Within acceptable tolerance range
• Material Flammability Rating: UL94 V-0 or equivalent
• RoHS Compliance Status: RoHS Compliant or ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The Molex KK254 series connectors 1718560012 and 1718561012 satisfy all primary matching criteria and maintain compatibility with the original TE Connectivity 4-647050-2 design specifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 4-647050-2 is classified as obsolete, making it unavailable for new production orders. Both Molex substitute parts (1718560012 and 1718561012) maintain active product status, ensuring long-term availability and supply chain reliability.

Compliance and Certification: Both substitute parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. The original TE Connectivity part is RoHS Compliant. The Molex alternatives carry UL94 V-2 flammability ratings compared to the original UL94 V-0 rating; however, both ratings satisfy standard safety requirements for rectangular connector applications.

Contact Finish Differentiation: Molex 1718560012 features tin-plated mating contacts matching the original TE Connectivity specification. Molex 1718561012 features gold-plated mating contacts, providing enhanced corrosion resistance and contact reliability in demanding environments. Selection between these two variants depends on application-specific requirements for contact durability and environmental exposure.

Dimensional Compatibility: Minor dimensional variations exist in contact length and insulation height between the original and substitute parts. These variations remain within acceptable tolerance ranges for standard through-hole PCB mounting applications and do not affect mechanical or electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can Molex 1718560012 and 1718561012 directly replace TE Connectivity 4-647050-2 in existing designs?

A: Both Molex parts satisfy all primary matching criteria including connector type, contact type, position count, pitch spacing, mounting type, termination method, shrouding configuration, and fastening mechanism. Direct substitution is supported for applications where the specified electrical and mechanical parameters are met.

Q: What is the difference between Molex 1718560012 and 1718561012?

A: The primary difference is the mating contact finish. Molex 1718560012 features tin-plated mating contacts (60.0µin thickness), while Molex 1718561012 features gold-plated mating contacts (15.0µin thickness). Both parts are electrically and mechanically equivalent. Gold plating provides superior corrosion resistance and is preferred for applications with extended shelf life or harsh environmental conditions.

Q: Are there voltage or current rating differences between the original and substitute parts?

A: The TE Connectivity 4-647050-2 specifies a 250VAC voltage rating. The Molex substitute parts do not provide explicit voltage or current ratings in their specifications. For applications requiring specific voltage or current ratings, verification against application requirements is necessary.

Q: What is the significance of the UL94 V-0 versus UL94 V-2 flammability ratings?

A: The original TE Connectivity part carries UL94 V-0 rating, indicating superior flame resistance. The Molex substitutes carry UL94 V-2 rating, which also meets standard safety requirements but with slightly lower flame resistance performance. Selection depends on application-specific flammability requirements.

Q: Are the dimensional differences between parts significant for PCB layout?

A: Minor dimensional variations exist in contact length and insulation height. The TE Connectivity part has an overall contact length of 0.550" (13.97mm) and insulation height of 0.347" (8.81mm), while Molex parts measure 0.510" (12.95mm) and 0.322" (8.18mm) respectively. These differences are within acceptable tolerance ranges for standard through-hole mounting and do not require PCB redesign.

Q: What is the packaging configuration for substitute parts?

A: Both Molex substitute parts are supplied in bulk packaging, consistent with standard connector distribution methods.

Q: Are both substitute parts suitable for automotive, medical, and telecommunications applications?

A: Both Molex 1718560012 and 1718561012 are specified for automotive, general purpose, medical, and telecommunications applications, providing broad application compatibility.
