Molex 0719730308 Equivalent & Substitute Parts

Part Overview

The Molex 0719730308 is a 16-position receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole, right-angle PCB mounting. This connector features gold-plated mating contacts, tin-plated posts, and is part of the C-Grid 71973 series. The part is currently active in production with 938 units in stock.

Substitute parts are identified when equivalent connectors share the same core electrical and mechanical specifications: 16 positions, 0.100" pitch, 2-row configuration, through-hole right-angle mounting, solder termination, and push-pull fastening. Finding alternatives is necessary for supply chain flexibility, design optimization, and compliance requirements across different manufacturing regions.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0719730308 is determined by strict adherence to the following core parameters:

16-position receptacle configuration with female socket contacts
0.100" (2.54mm) mating pitch and row spacing
2-row arrangement
Through-hole, right-angle PCB mounting
Solder termination with push-pull fastening
Phosphor bronze contact material with square contact geometry
UL94 V-0 flammability rating
MSL 1 moisture sensitivity level

All three substitute parts meet these core criteria. Variations in secondary parameters such as contact finish thickness, insulation material composition, insulation height, contact post length, and compliance certifications do not disqualify substitution eligibility but must be evaluated for specific application requirements.

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the Molex 0719730308 based on core electrical and mechanical parameters. Selection should be based on compliance requirements and product status:

TE Connectivity 1-535512-8 is an active product with extended operating temperature range (-55°C ~ 125°C). However, this part is RoHS non-compliant and REACH-affected, making it unsuitable for applications requiring RoHS3 compliance or REACH compliance.

Amphenol ICC 89883-308LF is an active product with RoHS compliance and REACH-affected status. Operating temperature range is not specified. This part features tin-plated mating contacts, differing from the gold-plated mating contacts of the main part. Insulation material is thermoplastic rather than liquid crystal polymer.

Harwin M20-7880846 is an active product with ROHS3 compliance and REACH unaffected status, matching the compliance profile of the main part. Operating temperature range matches the main part (-40°C ~ 105°C). This part features tin-plated mating contacts rather than gold-plated contacts. Current rating is specified at 3A with 1000V voltage rating.

For applications requiring RoHS3 and REACH compliance, the Harwin M20-7880846 is the preferred substitute. For applications with extended temperature requirements and non-RoHS environments, the TE Connectivity 1-535512-8 is suitable. The Amphenol ICC 89883-308LF serves applications requiring RoHS compliance without REACH restrictions.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-535512-8 be used as a direct replacement in RoHS3-compliant designs?

A: No. The TE Connectivity 1-535512-8 is RoHS non-compliant. Use this part only in applications where RoHS compliance is not required.

Q: What is the difference between gold-plated and tin-plated mating contacts?

A: The Molex 0719730308 features gold-plated mating contacts (30.0µin thickness). The Amphenol ICC 89883-308LF and Harwin M20-7880846 feature tin-plated mating contacts. Both finishes provide adequate electrical conductivity and corrosion resistance for standard applications. Gold plating offers superior corrosion resistance in high-humidity or corrosive environments.

Q: Are the insulation height and contact post length differences significant?

A: Insulation heights range from 0.224" to 0.238" and contact post lengths range from 0.114" to 0.120" across all parts. These minor variations (within 0.014" for height and 0.006" for post length) are within typical PCB design tolerances and do not affect mechanical compatibility for standard through-hole mounting applications.

Q: Which substitute part has the highest current rating?

A: The Harwin M20-7880846 specifies a current rating of 3A. The Molex 0719730308 and TE Connectivity 1-535512-8 do not specify current ratings. The Amphenol ICC 89883-308LF does not specify a current rating.

Q: What is the difference in operating temperature ranges?

A: The Molex 0719730308 and Harwin M20-7880846 operate from -40°C to 105°C. The TE Connectivity 1-535512-8 operates from -55°C to 125°C, providing extended low and high temperature capability. The Amphenol ICC 89883-308LF does not specify an operating temperature range.

Q: Are all substitute parts available in the same packaging?

A: Yes. All parts are supplied in tube packaging, consistent with the main part.

Q: Which substitute part matches the compliance profile of the Molex 0719730308?

A: The Harwin M20-7880846 matches the compliance profile with ROHS3 compliance and REACH unaffected status. The Molex 0719730308 is also ROHS3 compliant and REACH unaffected.
