Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1-1969543-4 are identified based on strict alignment with core electrical and mechanical parameters. The substitution logic requires equivalence in the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 14
• Number of Rows: 2
• Pitch - Mating: 0.098" (2.50mm)
• Row Spacing - Mating: 0.098" (2.50mm)
• Mounting Type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Kinked Pin, Solder
• Style: Board to Cable/Wire
• Voltage Rating: 250V or higher
• RoHS Status: ROHS3 Compliant

The Molex 1053102114 connector satisfies all mandatory matching parameters and is classified as a direct substitute. Both connectors maintain identical positional configuration, pitch spacing, mounting methodology, and regulatory compliance status. Variations in contact geometry, insulation material, fastening mechanism, and operating temperature range do not preclude substitution when application requirements fall within the overlapping performance envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 1-1969543-4 and Molex 1053102114 connectors maintain active product status and full ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. The connectors are functionally equivalent for applications requiring 14-position, 2-row, 2.5mm pitch header configurations with through-hole mounting and solder termination.

Selection between these parts should be based on the following engineering considerations:

TE Connectivity 1-1969543-4 is suitable for applications requiring the extended lower operating temperature limit of -55°C and the specified current rating of 4.2A. The polyamide insulation material and friction lock fastening mechanism are established in legacy designs.

Molex 1053102114 is suitable for applications operating within the -40°C to 105°C temperature range. The liquid crystal polymer insulation material provides enhanced dimensional stability and chemical resistance. The latch holder fastening mechanism offers alternative mating security. This part is available in higher inventory quantity (1179 pcs vs. 777 pcs).

Both connectors support 250V operation and are suitable for general-purpose, industrial, and lighting applications. Packaging differences (bulk vs. tray) may influence procurement and assembly workflows but do not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1053102114 be used as a direct replacement for the TE Connectivity 1-1969543-4 in existing designs?

A: Yes. Both connectors share identical positional configuration (14 positions, 2 rows), pitch spacing (2.5mm), mounting methodology (through-hole), and voltage rating (250V). The connectors are mechanically and electrically compatible for board-to-cable/wire applications. Design verification is required only if the application operates below -40°C, as the Molex part specifies a minimum operating temperature of -40°C versus -55°C for the TE Connectivity part.

Q: What are the differences in contact geometry between these two connectors?

A: The TE Connectivity 1-1969543-4 features circular contact geometry, while the Molex 1053102114 uses square contact geometry. Both contacts are brass with tin finish and are compatible with standard 2.5mm pitch mating receptacles. Contact geometry differences do not affect electrical performance or mating compatibility.

Q: How do the insulation materials differ, and does this affect substitution?

A: The TE Connectivity connector uses polyamide (PA66/Nylon 6/6) insulation, while the Molex connector uses liquid crystal polymer (LCP) insulation. LCP provides superior dimensional stability, lower moisture absorption, and enhanced chemical resistance. Both materials are UL94 V-0 rated or equivalent and do not preclude substitution. Material selection may be relevant for applications with extreme environmental exposure or tight tolerance requirements.

Q: What is the difference between friction lock and latch holder fastening?

A: The TE Connectivity connector uses friction lock fastening, which relies on mechanical interference for mating security. The Molex connector uses latch holder fastening, which provides positive mechanical locking. Both fastening methods are suitable for board-to-cable/wire applications. Latch holder fastening may be preferred in high-vibration or high-shock environments.

Q: Are there inventory or packaging considerations for substitution?

A: The TE Connectivity part is supplied in bulk packaging with 777 pcs in stock. The Molex part is supplied in tray packaging with 1179 pcs in stock. Packaging format may influence assembly line compatibility and procurement lead times but does not affect connector performance or compatibility.

Q: Does the difference in contact post length affect compatibility?

A: The TE Connectivity connector has a contact post length of 0.134" (3.40mm), while the Molex connector has 0.126" (3.20mm). Both lengths are within standard through-hole PCB mounting specifications and do not affect compatibility with standard 2.5mm pitch receptacles or mating connectors.

Q: What is the operating temperature consideration for substitution?

A: The TE Connectivity connector operates from -55°C to 105°C, while the Molex connector operates from -40°C to 105°C. For applications operating below -40°C, the TE Connectivity part is required. For applications within the -40°C to 105°C range, both connectors are suitable.

Q: Are both connectors RoHS compliant?

A: Yes. Both the TE Connectivity 1-1969543-4 and Molex 1053102114 are ROHS3 compliant and REACH unaffected, confirming compliance with current environmental and regulatory standards.
