Engineering Selection Recommendations

Primary Selection (Direct Equivalent): The TE Connectivity 1-103688-4 remains the specified component when the operating temperature minimum of -65°C is required and black color is mandatory. This part is Active status with RoHS3 compliance and established supply availability.

Molex 0050579015 and 0050579315 (SL 70066 Series): Both Molex alternatives provide equivalent functionality with superior inventory availability (5141 and 4871 units respectively). These parts are suitable for applications where the operating temperature minimum of -40°C satisfies design requirements. RoHS3 compliance and unlimited MSL rating are maintained. The polyester, glass-filled insulation material provides alternative material composition within the same functional class.

Amphenol ICC 65039-022LF (Mini-PV™, Basics+ Series): This substitute maintains black color specification and RoHS compliance. Operating temperature minimum of -40°C applies. The polyphenylene, modified insulation material offers alternative material properties. REACH Affected status requires verification for applications subject to REACH regulations.

Amphenol ICC 65240-015LF (DUBOX™, MezzSelect™, Basics+ Series): This option provides the widest operating temperature range (-65°C ~ 125°C), matching the lower temperature limit of the original part while extending the upper limit. Blue color specification differs from the original black housing. Thermoplastic, glass-filled insulation aligns with the original material class. RoHS compliance and REACH Affected status are noted. This part is suitable for applications requiring extended high-temperature performance.

All substitute parts maintain Active product status and unlimited moisture sensitivity rating, ensuring compatibility with standard storage and handling protocols.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0050579015 or 0050579315 be used as direct replacements for the TE Connectivity 1-103688-4?

A: Yes, both Molex parts are parametric equivalents. They share identical connector type, contact type, position count, pitch, row configuration, mounting type, and termination method. The operating temperature minimum differs (-40°C versus -65°C). Selection depends on whether your application requires operation below -40°C. Both parts are RoHS3 compliant with unlimited MSL rating.

Q: What is the significance of the color difference in the Amphenol ICC 65240-015LF?

A: The 65240-015LF housing is blue rather than black. Color specification is a visual identification feature and does not affect electrical or mechanical function. Selection should be based on application requirements for connector identification or assembly documentation standards.

Q: How do the insulation materials differ among the substitute parts?

A: The original TE part uses thermoplastic insulation. Molex substitutes use polyester, glass-filled material. The Amphenol ICC 65039-022LF uses polyphenylene, modified material. The Amphenol ICC 65240-015LF uses thermoplastic, glass-filled material. All materials are suitable for the specified operating temperature ranges and provide equivalent functional performance within their respective temperature limits.

Q: Which substitute part offers the best temperature performance?

A: The Amphenol ICC 65240-015LF provides the extended operating range of -65°C ~ 125°C, compared to the original -65°C ~ 105°C specification. This part is suitable for applications requiring operation at temperatures above 105°C. The lower temperature limit matches the original specification.

Q: Are all substitute parts RoHS compliant?

A: Yes. The TE Connectivity 1-103688-4, Molex 0050579015, and Molex 0050579315 are RoHS3 compliant. The Amphenol ICC parts (65039-022LF and 65240-015LF) are RoHS compliant. All parts meet regulatory requirements for lead-free and restricted substance compliance.

Q: What inventory considerations apply to these substitutes?

A: The original TE part has 1035 units in stock. Molex alternatives offer significantly higher availability (5141 and 4871 units). Amphenol ICC parts have comparable availability to the original (1073 and 1014 units). Selection based on inventory should consider lead time requirements and supply chain continuity.

Q: Do all parts require the same contact specifications?

A: Yes. All parts are receptacle housings for 15-position, 0.100" pitch crimp-terminated female socket contacts. Contact compatibility is determined by pitch and position count, which are identical across all listed parts. Contacts are not included with any housing and must be sourced separately.

Q: What is the significance of REACH status differences?

A: The TE Connectivity and Molex parts show REACH Unaffected or Vendor Undefined status. The Amphenol ICC parts show REACH Affected status. Applications subject to REACH regulations should verify compliance requirements with the specific manufacturer. REACH Affected status indicates the substance is subject to REACH authorization or restriction provisions.
