Substitute Part Grouping Explanation

Substitution eligibility for the 66506-050 is determined by strict equivalence across the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (20)
Number of rows (2)
Mating pitch (0.100" / 2.54mm)
Row spacing (0.100" / 2.54mm)
Shrouding configuration (Shrouded - 4 Wall)
Mounting method (Through Hole)
Termination type (Solder)
Fastening mechanism (Push-Pull)
Contact shape (Square)
Flammability rating (UL94 V-0)
Insulation color (Black)
MSL rating (1 - Unlimited)

All three substitute parts meet these core electrical and mechanical requirements. Variations in contact length, contact finish thickness, insulation material composition, and compliance certifications do not affect functional interchangeability within the specified parameter set.

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the 66506-050 based on core electrical and mechanical parameters. Selection should be based on the following criteria:

Molex 0702462001 and 0702462004 (C-Grid 70246 Series): Both parts are ROHS3 compliant and REACH unaffected, making them suitable for applications requiring enhanced environmental compliance. These parts offer superior inventory availability (6569 and 4773 units respectively) and are packaged in trays. The primary distinction between these two Molex variants is contact finish thickness on the mating surface (15.0µin versus 5.00µin), which does not affect functional interchangeability.

TE Connectivity 103309-5 (AMP-Latch Series): This part maintains RoHS non-compliant and REACH affected status consistent with the original 66506-050. It features a specified operating temperature range of -65°C to 105°C and a current rating of 1A per contact. The part is available in bulk packaging with 1500 units in stock. Contact material differs (brass versus phosphor bronze), and insulation height is slightly elevated at 0.388" (9.86mm).

For applications requiring RoHS3 compliance and REACH unaffected status, select either Molex substitute. For applications requiring consistency with the original part's compliance profile, select the TE Connectivity 103309-5.

Frequently Asked Questions (FAQ)

Q: Are these parts mechanically interchangeable with the 66506-050?

A: Yes. All substitute parts share identical connector type, contact configuration, position count, row arrangement, mating pitch, row spacing, shrouding design, mounting method, termination type, and fastening mechanism. Variations in contact length, insulation material, and contact finish do not affect mechanical fit or functional operation within the specified parameter set.

Q: What is the significance of the RoHS and REACH compliance differences?

A: The Molex parts (0702462001 and 0702462004) are ROHS3 compliant and REACH unaffected, meeting stricter environmental regulations required in certain markets and applications. The 66506-050 and TE Connectivity 103309-5 are RoHS non-compliant and REACH affected. Selection depends on end-use regulatory requirements.

Q: How do contact finish thickness variations affect performance?

A: Contact finish thickness is provided as specification data. All parts meet UL94 V-0 flammability requirements and maintain gold or equivalent mating surface finishes. Functional performance within the specified parameter set is not affected by the documented finish thickness variations.

Q: What packaging considerations apply to these substitutes?

A: The 66506-050, 0702462001, and 0702462004 are supplied in tray packaging. The TE Connectivity 103309-5 is supplied in bulk packaging. Procurement and handling procedures may differ based on packaging format.

Q: Can the TE Connectivity 103309-5 be used in applications requiring RoHS3 compliance?

A: No. The TE Connectivity 103309-5 is RoHS non-compliant. For applications requiring RoHS3 compliance, select either Molex part (0702462001 or 0702462004).

Q: Are there differences in current or voltage ratings between these parts?

A: The TE Connectivity 103309-5 specifies a current rating of 1A per contact and an operating temperature range of -65°C to 105°C. The 66506-050 and Molex parts do not provide current or voltage ratings in the available specification data. Consult detailed datasheets for complete electrical performance parameters if required for your application.
