Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 1722562003 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (3)
• Pitch specification (0.138" / 4.60mm)
• Number of rows (1)
• Mounting configuration (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening mechanism (Latch Lock)
• Color (Natural)
• Compliance certifications (ROHS3, REACH Unaffected)

The substitute part 1722564103 maintains full electrical and mechanical compatibility with the original part across all specified parameters. The primary distinction is product status: the original part is obsolete, while the substitute is active in production with enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1722564103 is the direct active equivalent for the obsolete 1722562003. Both parts maintain identical electrical and mechanical specifications within the Ultra-Fit 172256 series, ensuring form-fit-function compatibility in existing applications.

Selection of the substitute part is supported by:

• Continuous production status and established supply chain availability
• Full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements
• Identical connector architecture, pitch, and termination specifications
• MSL 1 rating providing unlimited shelf life stability

The substitute part is suitable for new designs, replacement procurement, and system upgrades where the original part is no longer available.

Frequently Asked Questions (FAQ)

Q: Are the 1722562003 and 1722564103 mechanically interchangeable?

A: Yes. Both parts are 3-position receptacle housings with identical pitch (0.138" / 4.60mm), mounting configuration, and fastening mechanism. They are designed for the same contact set and mating plug configurations within the Ultra-Fit 172256 series.

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

A: The primary difference is product status. The 1722562003 is obsolete, while the 1722564103 is active in production. The substitute includes enhanced features (Glow Wire Compliant, Terminal Position Lock) and specified operating temperature range (-40°C ~ 105°C). Both maintain identical core electrical and mechanical specifications.

Q: Can I use the 1722564103 as a direct replacement in existing assemblies?

A: Yes. The substitute part maintains full compatibility with existing contact sets, mating connectors, and PCB layouts designed for the original part. No design modifications are required.

Q: Are there packaging differences between these parts?

A: The original part was supplied with unspecified packaging, while the substitute is available in bulk packaging. This does not affect functional or mechanical compatibility.

Q: Do both parts meet current compliance standards?

A: Yes. Both the original and substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.
