Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 640601-7 and the identified equivalent 3-640601-7 is based on strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (7)
• Contact type (Female Socket)
• Pitch (0.156" / 3.96mm)
• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Wire type (Discrete or Ribbon Cable)
• Contact finish thickness (80.0µin / 2.03µm)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging In-Line)
• Fastening type (Locking Ramp)
• Number of rows (1)
• Feed-through feature

Regulatory & Environmental Parameters:

• Moisture Sensitivity Level (1 - Unlimited)
• ECCN classification (EAR99)
• HTSUS code (8536.69.8000)

The primary difference between the main part and substitute is the contact finish material (tin-lead versus tin) and RoHS compliance status, with the substitute offering RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

640601-7 Selection Criteria:

• Applications where tin-lead contact finish is specified or required
• Systems with REACH Affected material declarations
• Existing designs with established compatibility to this specific contact finish

3-640601-7 Selection Criteria:

• New designs requiring RoHS compliance
• Applications subject to RoHS regulatory requirements
• Systems where tin contact finish meets performance specifications
• Bulk packaging requirements for high-volume production

Both parts maintain identical electrical and mechanical performance across all critical parameters including connector type, position count, pitch, IDC termination, wire gauge, mounting configuration, and fastening mechanism. The substitute part 3-640601-7 provides an active production alternative with improved regulatory compliance status while maintaining full functional equivalence.

Frequently Asked Questions (FAQ)

Q: Are 640601-7 and 3-640601-7 electrically interchangeable?

A: Yes. Both connectors are electrically equivalent across all specified parameters including contact type, number of positions, pitch, IDC termination method, wire gauge, and contact finish thickness. The difference in contact finish material (tin-lead versus tin) does not affect electrical performance within the specified parameters.

Q: What is the primary difference between these two parts?

A: The main difference is the contact finish material. The 640601-7 features a tin-lead finish and is RoHS non-compliant, while the 3-640601-7 features a tin finish and is RoHS compliant. Both maintain identical contact finish thickness of 80.0µin (2.03µm).

Q: Can I use 3-640601-7 as a direct replacement for 640601-7 in existing designs?

A: The 3-640601-7 is mechanically and electrically compatible with the 640601-7 across all specified parameters. Compatibility depends on whether your application or regulatory requirements specifically mandate tin-lead contact finish or RoHS compliance status.

Q: What does the packaging difference mean?

A: The 640601-7 packaging is not specified in the documentation, while the 3-640601-7 is supplied in bulk packaging. Bulk packaging typically indicates standard production quantities without special packaging requirements.

Q: Are both parts currently in production?

A: Yes. Both the 640601-7 and 3-640601-7 are listed as active products with current inventory availability (769 and 795 units respectively).

Q: What is the significance of the REACH Affected status on 640601-7?

A: The 640601-7 is marked as REACH Affected, indicating it contains substances of concern under REACH regulations. The 3-640601-7 shows Vendor Undefined REACH status. This distinction may be relevant for applications subject to REACH compliance requirements.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both connectors support discrete or ribbon cable termination via IDC method at 22 AWG wire gauge.

Q: What is the feed-through feature?

A: The feed-through feature indicates that the connector allows signal or power to pass through the connector body, enabling daisy-chain or series configurations in cable assemblies.
