Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 641992-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 9
• Pitch - Mating: 0.156" (3.96mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Friction Lock
• Shrouding: Shrouded - 1 Wall
• Operating Temperature Range: -55°C ~ 105°C
• Voltage Rating: 600VAC
• Material Flammability Rating: UL94 V-0
• Contact Material: Copper Alloy
• Insulation Material: Thermoplastic, Glass Filled
• Contact Finish: Tin (both mating and post)
• Contact Shape: Circular
• Insulation Height: 0.425" (10.80mm)

The substitute part 640388-9 meets all mandatory matching parameters and belongs to the same MTA-156 series. Both parts are manufactured by TE Connectivity AMP Connectors and maintain electrical and mechanical compatibility within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 640388-9 serves as the active equivalent substitute for the obsolete 641992-3. Both connectors maintain identical electrical and mechanical specifications across all critical parameters, including pitch, contact configuration, operating temperature range, voltage rating, and material compliance.

The primary distinction between these parts is product status: the 641992-3 is obsolete, while the 640388-9 is active and currently manufactured. The 640388-9 is ROHS3 compliant and carries an unlimited moisture sensitivity level, matching the compliance profile of the original part.

A secondary difference exists in contact post length: the 641992-3 features a 0.175" (4.45mm) post length, while the 640388-9 features a 0.125" (3.18mm) post length. This variation results in an overall contact length difference of 0.050" (1.27mm). Applications requiring the exact post length of the original part must evaluate this dimensional variance against specific board layout and mating requirements.

The 640388-9 is supplied in bulk packaging and maintains full position loading across all nine positions, whereas the 641992-3 was loaded with five positions. For applications utilizing all nine positions, the 640388-9 provides complete functionality without modification.

Frequently Asked Questions (FAQ)

Q: Can the 640388-9 directly replace the 641992-3 in existing designs?

A: The 640388-9 is electrically and mechanically compatible with the 641992-3 across all critical parameters including pitch, contact type, operating temperature, and voltage rating. Both connectors are MTA-156 series headers with identical shrouding, termination method, and material specifications. The primary consideration is the contact post length difference of 0.050" (1.27mm), which may affect board layout depending on application-specific requirements.

Q: What is the significance of the "Number of Positions Loaded" difference?

A: The 641992-3 was supplied with five of nine positions loaded, while the 640388-9 is supplied with all nine positions loaded. This difference reflects manufacturing configuration only. Both connectors support the full nine-position capacity. Applications requiring fewer than nine positions can utilize the 640388-9 without modification; unused positions remain available for future expansion.

Q: Are there compliance or certification differences between these parts?

A: Both the 641992-3 and 640388-9 are ROHS3 compliant, carry a UL94 V-0 material flammability rating, and maintain an unlimited moisture sensitivity level (MSL 1). Electrical and thermal specifications are identical. The primary compliance distinction is product status: the 641992-3 is obsolete, while the 640388-9 is active and subject to ongoing manufacturing support.

Q: How does the contact post length difference affect substitution?

A: The 640388-9 features a 0.050" (1.27mm) shorter contact post compared to the 641992-3. This dimensional variance affects the overall contact length and may influence solder joint geometry and board-level clearances. Applications with tight vertical spacing constraints or specific solder profile requirements must evaluate this difference against PCB design specifications.

Q: What packaging differences exist between these parts?

A: The 641992-3 was supplied with unspecified packaging, while the 640388-9 is supplied in bulk packaging. This distinction affects procurement and handling procedures but does not impact electrical or mechanical performance.

Q: Are both parts suitable for the same temperature and voltage operating conditions?

A: Yes. Both the 641992-3 and 640388-9 operate across the identical temperature range of -55°C to 105°C and carry a 600VAC voltage rating. Current rating varies by wire gauge for both connectors. Thermal and electrical performance characteristics are equivalent.
