Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 644702-3 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (3)
• Pitch (0.100" / 2.54mm)
• Number of rows (1)
• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Contact finish material (Gold)
• Contact finish thickness (30.0µin / 0.76µm)

Mechanical Parameters:

• Mounting type (Free Hanging In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Series designation (MTA-100)
• Color (Red)
• Feed Through feature

The substitute part 3-644702-3 meets all these criteria and is therefore a direct functional equivalent. The primary distinction between the main part and its substitute is product status and packaging configuration.

Engineering Selection Recommendations

The substitute part 3-644702-3 is the direct equivalent for the obsolete 644702-3. Selection of the substitute part is based on the following engineering considerations:

Product Status: The main part 644702-3 is classified as obsolete, while the substitute 3-644702-3 maintains active product status with confirmed inventory availability (5899 pieces in stock). This ensures long-term supply chain reliability and component accessibility.

Regulatory Compliance: The substitute part 3-644702-3 is RoHS Compliant, whereas the main part is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the substitute part satisfies these regulatory obligations.

Functional Equivalence: All electrical and mechanical parameters are identical between the two parts. The connector maintains the same MTA-100 series designation, 3-position configuration, 0.100" pitch, IDC termination method, 22 AWG wire gauge, gold contact finish, and mounting characteristics.

Packaging: The substitute part is supplied in bulk packaging, which may differ from the original part's packaging configuration. Bulk packaging does not affect connector functionality or performance.

For new designs, field service replacements, and production applications requiring RoHS compliance, the 3-644702-3 substitute part is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 3-644702-3 substitute be used as a direct replacement for the 644702-3 in existing designs?

A: Yes. The 3-644702-3 is electrically and mechanically identical to the 644702-3. All connector parameters, including pitch, position count, contact type, termination method, and wire gauge, are equivalent. The substitute part functions identically in the same circuit and mechanical applications.

Q: What is the primary difference between the 644702-3 and 3-644702-3?

A: The primary differences are product status and regulatory compliance. The 644702-3 is obsolete and RoHS non-compliant, while the 3-644702-3 is an active product that is RoHS Compliant. Both parts are functionally identical.

Q: Does the RoHS compliance status of the 3-644702-3 affect its electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. The 3-644702-3 maintains identical electrical characteristics, contact resistance, and signal integrity as the original part.

Q: Are there packaging differences between the two parts?

A: Yes. The 644702-3 packaging specification is not defined in the available data, while the 3-644702-3 is supplied in bulk packaging. Bulk packaging does not affect connector performance or compatibility.

Q: Can the 3-644702-3 accommodate the same wire gauge and termination method as the original part?

A: Yes. Both parts support 22 AWG wire gauge and IDC (Insulation Displacement Contact) termination. The connector accepts discrete or ribbon cable with identical termination characteristics.

Q: Is the 3-644702-3 suitable for applications requiring RoHS compliance?

A: Yes. The 3-644702-3 is RoHS Compliant and meets regulatory requirements for applications subject to RoHS directives.

Q: What is the moisture sensitivity level for the 3-644702-3?

A: The moisture sensitivity level (MSL) is 1 (Unlimited), indicating no moisture sensitivity restrictions. The connector can be stored and handled without special moisture control measures.

Q: Are both parts classified under the same export control regulations?

A: Yes. Both the 644702-3 and 3-644702-3 are classified under ECCN EAR99 and HTSUS 8536.69.8000, indicating identical export control and tariff classifications.
