Molex 0719731004 Equivalent & Substitute Parts

Part Overview

The Molex 0719731004 is an 8-position receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole, right-angle board-to-board or cable applications. This connector features gold-plated mating contacts, push-pull fastening, and is rated for operating temperatures from -40°C to 105°C. The part is active in production with 1,146 units currently in stock.

Substitute parts may be required due to inventory constraints, application-specific requirements, or design revisions that permit alternative contact finishes or insulation materials while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0719731004 is determined by strict equivalence in the following parameters:

8-position receptacle configuration
0.100" (2.54mm) mating pitch
2-row layout with 0.100" (2.54mm) row spacing
Through-hole, right-angle mounting
Solder termination

Engineering Selection Recommendations

All three substitute parts maintain active product status and meet the core mechanical and electrical requirements for direct substitution with the Molex 0719731004.

Amphenol ICC 89883-304LF provides the closest contact finish match with gold-plated mating surfaces, maintaining the same electrical contact characteristics as the original part. This option is suitable for applications where contact finish consistency is a design requirement.

Amphenol ICC 89883-404LF features tin-plated mating contacts and is functionally equivalent for applications where contact finish variation is acceptable. Note that this part carries REACH Affected status, requiring compliance verification for regulated substance applications.

Harwin M20-7880446 offers the highest current inventory availability and specifies rated electrical parameters (3A current, 1000V voltage). This part is suitable for applications requiring documented electrical ratings and is ROHS3 compliant with REACH Unaffected status.

All substitute parts maintain UL94 V-0 flammability compliance and MSL 1 moisture sensitivity ratings. Minor variations in insulation height and contact post length fall within acceptable mechanical tolerances for standard through-hole PCB mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 89883-304LF directly replace the Molex 0719731004?

A: Yes. Both parts share identical mating pitch (0.100"), row configuration (2 rows at 0.100" spacing), position count (8), mounting type (through-hole right-angle), and fastening mechanism (push-pull). The gold contact finish on the 89883-304LF matches the original part specification.

Q: What is the difference between the Amphenol ICC 89883-304LF and 89883-404LF?

A: The primary difference is contact finish. The 89883-304LF features gold-plated mating contacts, while the 89883-404LF uses tin plating. Both maintain identical mechanical dimensions, pitch, and row spacing. The 89883-404LF carries REACH Affected status, requiring compliance assessment for applications subject to REACH regulations.

Q: Are there dimensional compatibility concerns with the Harwin M20-7880446?

A: The Harwin part exhibits minor dimensional variations: insulation height of 0.232" (5.90mm) versus the original 0.224" (5.69mm), and contact post length of 0.118" (3.00mm) versus 0.120" (3.05mm). These variations remain within acceptable tolerances for standard through-hole PCB mounting and do not affect mating compatibility with corresponding plug connectors.

Q: Which substitute part should be selected for high-reliability applications?

A: Selection depends on specific application requirements. The Harwin M20-7880446 provides documented electrical ratings (3A, 1000V) and ROHS3 compliance. The Amphenol ICC 89883-304LF maintains gold contact finish consistency. All three parts meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications.

Q: Is the Amphenol ICC 89883-404LF suitable for automotive applications?

A: The 89883-404LF is listed for automotive applications and maintains UL94 V-0 compliance. However, the REACH Affected status requires verification against specific automotive supply chain requirements and regional regulations before implementation.

Q: What are the inventory implications of selecting a substitute part?

A: The Harwin M20-7880446 offers the highest current availability at 5,807 units in stock, followed by the Amphenol ICC 89883-304LF at 2,107 units. The original Molex 0719731004 has 1,146 units available. Substitute selection may be driven by supply chain lead time and inventory requirements.
