Frequently Asked Questions (FAQ)

Q: Can the Molex 5018763040 be used as a direct replacement for the Molex 5018763046 in existing designs?

A: Yes. Both connectors are electrically and mechanically equivalent within the iGrid 501876 series. They share identical pitch (0.079" / 2.00mm), position count (30), row configuration (2 rows), mounting type (through hole, right angle), contact material (brass), contact finish (tin), and voltage rating (250VAC/DC). No design modifications are required.

Q: What is the primary difference between these two part numbers?

A: The primary difference is product status. The 5018763046 is discontinued at DiGi Electronics, while the 5018763040 is active. The 5018763040 also offers higher inventory availability and is supplied in tray packaging.

Q: Are the insulation materials identical between these parts?

A: Both parts use polyamide (PA) nylon glass-filled insulation with identical insulation height (0.327" / 8.30mm) and UL94 V-0 flammability rating. The 5018763046 specifies "Polyamide (PA), Nylon, Glass Filled" while the 5018763040 specifies "Polyamide (PA66), Nylon 6/6, Glass Filled." Both formulations are functionally equivalent for this connector application.

Q: Will the 5018763040 fit the same PCB footprint as the 5018763046?

A: Yes. Both connectors have identical through-hole, right-angle mounting specifications, insulation height (0.327" / 8.30mm), and contact post length (0.126" / 3.20mm). PCB footprints are directly compatible.

Q: What is the operating temperature range for these connectors?

A: The 5018763046 specifies an operating temperature range of -40°C to 105°C. The 5018763040 does not specify an operating temperature range in the provided data; however, both parts share identical material composition and flammability rating, indicating equivalent thermal performance characteristics.

Q: Are there any compliance or certification differences between these parts?

A: Both parts carry UL94 V-0 material flammability certification. The 5018763040 includes RoHS3 compliance and REACH unaffected status in its specification. The 5018763046 does not specify these compliance statuses in the provided data.

Q: What packaging options are available?

A: The 5018763046 packaging is not specified in the provided data. The 5018763040 is supplied in tray packaging.
