Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 644893-5 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (5)
• Pitch specification (0.100" / 2.54mm)
• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 105°C)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact shape (Square)
• Insulation material (Polyester)
• Insulation height (0.410" / 10.41mm)
• Overall contact length (0.520" / 13.21mm)

Compliance Parameters:

• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1 - Unlimited)

The substitute part 3-644893-5 maintains full equivalence across all critical electrical and mechanical parameters. The primary distinction is product status transition from obsolete to active, along with updated contact finish specifications and enhanced RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-644893-5 is the direct equivalent for the obsolete 644893-5. Selection of the substitute part is supported by the following factors:

Product Status: The substitute part maintains active product status with TE Connectivity AMP Connectors, ensuring ongoing availability and manufacturing support. The main part is classified as obsolete, making the substitute the appropriate selection for new designs and ongoing production requirements.

Compliance and Certification: The substitute part carries RoHS Compliant status and REACH Unaffected designation, providing enhanced regulatory compliance compared to the main part's undefined status. Both parts maintain UL94 V-0 flammability rating and identical MSL 1 moisture sensitivity classification.

Electrical and Mechanical Equivalence: All critical electrical parameters including voltage rating (250VAC), operating temperature range (-55°C ~ 105°C), and mechanical specifications including pitch (0.100" / 2.54mm), mounting type (Through Hole), and shrouding configuration (Shrouded - 4 Wall) are identical between the main and substitute parts.

Contact Finish Specification: The substitute part features Tin contact finish on both mating and post surfaces, replacing the Tin-Lead finish of the main part. This change aligns with modern RoHS compliance requirements and does not affect electrical or mechanical compatibility.

Packaging Consideration: The substitute part is supplied in Bulk packaging, whereas the main part packaging specification is not provided. Packaging selection should be determined based on procurement and inventory management requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3-644893-5 substitute directly replace the 644893-5 in existing designs?

A: Yes. The 3-644893-5 maintains full electrical and mechanical equivalence with the 644893-5 across all critical parameters including connector type, contact configuration, pitch specification, voltage rating, operating temperature range, mounting type, and shrouding. Direct substitution is supported without design modification.

Q: What is the significance of the contact finish change from Tin-Lead to Tin?

A: The contact finish change reflects transition to RoHS-compliant manufacturing. Tin finish provides equivalent electrical performance and contact reliability for the specified voltage (250VAC) and current applications. The change does not affect mating compatibility or electrical characteristics.

Q: Why is the main part classified as obsolete?

A: The 644893-5 is classified as obsolete by TE Connectivity AMP Connectors. The active substitute 3-644893-5 is the current production equivalent and should be used for all new designs and ongoing procurement.

Q: Are there any differences in mechanical dimensions between the two parts?

A: No. Both parts share identical mechanical specifications including overall contact length (0.520" / 13.21mm), insulation height (0.410" / 10.41mm), contact length measurements, and shrouding configuration. Physical interchangeability is confirmed.

Q: What is the difference between the packaging specifications?

A: The main part packaging is not specified in available documentation. The substitute part 3-644893-5 is supplied in Bulk packaging. Packaging format should be selected based on procurement volume and inventory management requirements without affecting component performance.

Q: Are both parts suitable for the same applications?

A: Yes. Both parts are rated for General Purpose and Lighting applications with identical operating temperature ranges (-55°C ~ 105°C) and voltage ratings (250VAC). Application compatibility is maintained.

Q: What is the inventory status of these parts?

A: The main part 644893-5 has 993 pieces in stock as new original inventory. The substitute part 3-644893-5 has 913 pieces in stock as new original inventory. Availability should be confirmed with the supplier for current procurement requirements.

Q: Does the RoHS compliance status affect compatibility?

A: No. The substitute part's RoHS Compliant status and REACH Unaffected designation represent regulatory compliance improvements and do not affect electrical or mechanical compatibility with existing designs or mating components.
