Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 640499-2 and the equivalent part 2-640499-2 is based on identical electrical and mechanical parameters. Both parts maintain the same connector configuration, pitch spacing, contact arrangement, current and voltage ratings, and operating temperature range. The substitution is valid because the parts share the same core specifications for mating interface, mounting methodology, and performance characteristics.

The key parameters that determine substitution eligibility are:

• Connector type and contact type (Header, Male Pin)
• Position count and row configuration (4 positions, 2 rows)
• Pitch and row spacing (0.165" / 4.20mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Current and voltage ratings (6A, 250VAC)
• Operating temperature range (-55°C ~ 105°C)
• Contact material and mating finish (Phosphor Bronze, Gold)
• Insulation material and flammability rating (Polyamide/Nylon, UL94 V-0)

Parameter Comparison

Engineering Selection Recommendations

The substitute part 2-640499-2 is electrically and mechanically equivalent to the main part 640499-2 across all critical connector specifications. Both parts are active products from TE Connectivity AMP Connectors and maintain identical performance characteristics for mating interface, current handling, voltage rating, and operating temperature range.

The primary distinction between the parts is compliance status. The substitute part 2-640499-2 is ROHS3 compliant with REACH Unaffected status, whereas the main part 640499-2 is RoHS non-compliant with vendor-undefined REACH status. The substitute part also features a post contact finish of Tin instead of Tin-Lead, which aligns with RoHS3 requirements.

Selection between these parts should be based on regulatory compliance requirements for the end application. Applications requiring RoHS3 compliance should utilize part 2-640499-2. Applications without RoHS compliance constraints may use either part based on inventory availability. The substitute part offers higher inventory availability at 1859 pieces compared to 889 pieces for the main part.

Frequently Asked Questions (FAQ)

Q: Are the 640499-2 and 2-640499-2 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.165" / 4.20mm), row spacing (0.165" / 4.20mm), number of positions (4), number of rows (2), mounting type (Through Hole), shrouding configuration (Shrouded - 4 Wall), and contact dimensions. They are directly interchangeable in board-level applications.

Q: Are the 640499-2 and 2-640499-2 connectors electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including current rating (6A), voltage rating (250VAC), operating temperature range (-55°C to 105°C), contact material (Phosphor Bronze), and mating contact finish (Gold). They perform identically in electrical applications.

Q: What is the difference between the contact finishes on the post?

A: The main part 640499-2 features Tin-Lead post contact finish, while the substitute part 2-640499-2 features Tin post contact finish. This difference reflects the RoHS3 compliance status of the substitute part, which eliminates lead content. Both finishes provide equivalent electrical and mechanical performance for solder termination.

Q: Why should I select the 2-640499-2 substitute over the 640499-2?

A: The substitute part 2-640499-2 should be selected when RoHS3 compliance is required for the end application. The substitute part also offers higher inventory availability. Both parts are functionally equivalent for applications without specific compliance constraints.

Q: Can I use the 640499-2 in applications requiring RoHS3 compliance?

A: No. The main part 640499-2 is RoHS non-compliant. Applications requiring RoHS3 compliance must use the substitute part 2-640499-2.

Q: Are there any performance differences between these connectors?

A: No. Both connectors deliver identical performance across all electrical and mechanical parameters including current handling, voltage rating, operating temperature range, contact resistance characteristics, and mechanical durability.

Q: What is the REACH status difference between these parts?

A: The main part 640499-2 has vendor-undefined REACH status. The substitute part 2-640499-2 has REACH Unaffected status, indicating that the substance of concern restrictions do not apply to this part. For applications requiring defined REACH compliance documentation, the substitute part is the appropriate selection.
