Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors 4-794620-4 qualifies as an equivalent substitute based on the following critical parameters:

Connector geometry: Both parts feature 14 positions arranged in 2 rows with identical 0.118" (3.00mm) pitch and row spacing
Mounting configuration: Both are through-hole, right-angle headers with shrouded 4-wall design
Electrical interface: Both use male pin contacts with solder termination and locking ramp fastening
Environmental compliance: Both meet UL94 V-0 flammability rating and ROHS3 compliance
Operating temperature: Both support -40°C ~ 105°C range
Contact materials and finishes: Both use brass alloy contacts with gold mating finish (30.0µin) and tin post finish (100.0µin)

Substitution is valid where the application requirements align with the specified electrical and mechanical parameters of both connectors.

Engineering Selection Recommendations

Both the Molex 0430451402 and TE Connectivity 4-794620-4 are active production parts with equivalent electrical and mechanical specifications. Selection between these connectors should be based on:

Supply availability: The TE Connectivity part currently has 1601 units in stock versus 748 units for the Molex part
Voltage rating differential: The Molex part is rated for 600V while the TE Connectivity part is rated for 250V; applications requiring 600V operation must use the Molex connector
Current rating specification: The Molex part specifies 8A current rating; the TE Connectivity part current rating varies by wire gauge and must be confirmed for the specific application
Insulation material: Molex uses Liquid Crystal Polymer (LCP) glass-filled insulation; TE Connectivity uses Polyamide (PA) nylon insulation
Compliance certifications: Both parts meet ROHS3 compliance, UL94 V-0 flammability rating, and carry EAR99 ECCN classification

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-794620-4 replace the Molex 0430451402 in all applications?

A: Substitution is valid only when the application voltage requirement does not exceed 250V. The Molex part supports 600V operation; applications requiring this higher voltage rating must use the Molex connector.

Q: What are the key geometric compatibility factors?

A: Both connectors share identical mating pitch (0.118" / 3.00mm), row spacing (0.118" / 3.00mm), position count (14 in 2 rows), and insulation height (0.290" / 7.37mm). Both feature shrouded 4-wall design with right-angle through-hole mounting.

Q: Are there differences in contact specifications?

A: Both connectors use square male pin contacts with identical gold mating finish (30.0µin) and tin post finish (100.0µin). Contact material differs slightly: Molex uses brass alloy while TE Connectivity specifies brass. Both support the same operating temperature range (-40°C ~ 105°C).

Q: What packaging considerations apply?

A: Both parts are supplied in tray packaging with Moisture Sensitivity Level 1 (unlimited shelf life). Both carry identical HTSUS code 8536.69.4040 and EAR99 ECCN classification.

Q: How do the insulation materials compare?

A: The Molex connector uses Liquid Crystal Polymer (LCP) glass-filled insulation, while the TE Connectivity connector uses Polyamide (PA) nylon insulation. Both achieve UL94 V-0 flammability rating and black insulation color.

Q: What is the current rating difference?

A: The Molex part specifies a fixed 8A current rating. The TE Connectivity part current rating varies by wire gauge and must be confirmed based on the specific wire gauge used in the application.
