Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors within the MTA-100 series is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 14
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Operating Temperature Range: -55°C ~ 105°C
• Voltage Rating: 250VAC
• Material Flammability Rating: UL94 V-0
• Insulation Material: Thermoplastic
• Contact Material: Copper Alloy

Allowable Variations:

• Contact Finish - Mating: Gold or Tin
• Contact Finish - Post: Tin
• RoHS Compliance Status: RoHS Compliant or ROHS3 Compliant

Both finishes are applied to copper alloy contacts and are suitable for general-purpose board-to-cable/wire interconnections operating within the specified temperature and voltage ranges.

Inventory Availability:

• 4-641126-4: 748 pieces in stock
• 1-640454-4: 836 pieces in stock

Both parts are available in bulk packaging and maintain unlimited moisture sensitivity level (MSL 1) classification.

Frequently Asked Questions (FAQ)

Q: Can 1-640454-4 be used as a direct replacement for 4-641126-4?

A: Yes. Both connectors are MTA-100 series headers with identical 14-position, single-row configuration at 0.100" (2.54mm) pitch. All electrical and mechanical parameters match, including operating temperature range (-55°C ~ 105°C), voltage rating (250VAC), and through-hole solder termination. The allowable variation in mating contact finish (gold versus tin) does not prevent functional substitution in general-purpose applications.

Q: What is the difference between the contact finishes on these two parts?

A: The primary part 4-641126-4 has gold-plated mating contacts (15.0µin thickness), while the substitute part 1-640454-4 has tin-plated mating contacts. Both finishes are applied to the same copper alloy base material. Gold provides enhanced corrosion resistance and lower contact resistance, while tin is a standard industrial finish. Both are suitable for the specified operating conditions and voltage ratings.

Q: Are there any compatibility issues when substituting 1-640454-4 for 4-641126-4?

A: No compatibility issues exist. Both connectors share identical mechanical dimensions, pitch spacing, contact geometry, and mounting specifications. They are designed to mate with the same receptacle connectors and occupy identical board space. The fastening type specification differs (friction lock versus unspecified), but this does not affect mating compatibility.

Q: What is the significance of the RoHS compliance difference?

A: The primary part carries RoHS Compliant designation, while the substitute carries ROHS3 Compliant designation. ROHS3 represents an updated compliance framework. Both designations confirm the absence of restricted substances within regulatory limits. The substitute part meets current regulatory requirements.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes. Both connectors are functionally equivalent for board-to-cable/wire interconnection applications. They maintain identical electrical ratings (250VAC), thermal operating range (-55°C ~ 105°C), and mechanical specifications. Existing PCB layouts, mating receptacles, and wire gauge selections remain valid for either part.

Q: What is the current rating for these connectors?

A: Current rating varies by wire gauge for both parts. The connector itself is rated for 250VAC operation. Actual current capacity depends on the wire gauge selected during assembly and the specific application requirements.

Q: Are both parts available in the same packaging format?

A: Yes. Both 4-641126-4 and 1-640454-4 are supplied in bulk packaging. Both maintain MSL 1 (Unlimited) moisture sensitivity level, indicating no special storage or handling requirements.
