Substitute Part Grouping Explanation

Substitution between the main part number 1-641208-2 and the alternative part number 4-641208-2 is based on electrical and mechanical parameter equivalence within the MTA-156 series. Both parts maintain identical specifications for connector type, contact configuration, pitch, mounting method, termination style, shrouding design, and fastening mechanism. The primary distinction between these parts is packaging format and RoHS compliance status. The substitution logic is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Contact Type: Male Pin (identical)
• Pitch - Mating: 0.156" (3.96mm) (identical)
• Voltage Rating: 600VAC (identical)
• Operating Temperature Range: -55°C ~ 105°C (identical)

Mechanical Compatibility Parameters:

• Number of Positions: 12 (identical)
• Number of Rows: 1 (identical)
• Mounting Type: Through Hole (identical)
• Termination: Solder (identical)
• Shrouding: Shrouded - 1 Wall (identical)
• Fastening Type: Friction Lock (identical)

Physical Dimension Parameters:

• Contact Length - Mating: 0.400" (10.16mm) (identical)
• Contact Length - Post: 0.125" (3.18mm) (identical)
• Overall Contact Length: 0.650" (16.51mm) (identical)
• Insulation Height: 0.425" (10.80mm) (identical)

Both parts are classified as Active products within the same series and share identical material specifications, flammability ratings, and environmental classifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1-641208-2 and 4-641208-2 are active products manufactured by TE Connectivity within the MTA-156 series. Selection between these parts is determined by regulatory compliance requirements and packaging specifications.

1-641208-2 Selection Criteria:

• Applications where RoHS non-compliant components are acceptable
• Standard packaging requirements
• General purpose and industrial applications without RoHS mandates

4-641208-2 Selection Criteria:

• Applications requiring RoHS compliance
• Bulk packaging requirements for high-volume production
• Regulatory environments where RoHS certification is mandatory
• Industrial applications subject to environmental compliance standards

Both parts maintain identical electrical performance, mechanical compatibility, and thermal operating characteristics. The contact finish on the post differs between tin-lead (1-641208-2) and tin (4-641208-2), representing a compliance-driven material change. Both finishes are functionally equivalent for solder termination applications. Inventory availability differs between the two part numbers, with 4-641208-2 offering higher stock levels at 1352 pieces compared to 677 pieces for 1-641208-2.

Frequently Asked Questions (FAQ)

Q: Are the 1-641208-2 and 4-641208-2 electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including voltage rating (600VAC), operating temperature range (-55°C ~ 105°C), contact configuration (12-position male pin), and pitch (0.156"/3.96mm). Current rating varies by wire gauge for both parts identically.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (standard versus bulk), RoHS compliance status (non-compliant versus compliant), and contact finish on the post (tin-lead versus tin). All electrical and mechanical parameters remain identical.

Q: Can I use 4-641208-2 as a direct replacement for 1-641208-2?

A: Yes, for applications where RoHS compliance is acceptable or required. The 4-641208-2 is a direct functional equivalent with identical connector specifications, mounting characteristics, and performance parameters.

Q: Does the contact finish difference affect performance?

A: No. The change from tin-lead to tin post finish is a compliance-driven material modification. Both finishes are suitable for solder termination and provide equivalent electrical performance in this application.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications subject to RoHS mandates, select 4-641208-2. For applications without RoHS requirements, either part is suitable based on packaging and inventory needs.

Q: Are there any temperature or voltage limitations when substituting between these parts?

A: No. Both parts operate identically across the full temperature range (-55°C ~ 105°C) and voltage rating (600VAC). No derating or operational limitations apply to substitution.

Q: What is the significance of the packaging difference?

A: The 1-641208-2 uses standard packaging while 4-641208-2 uses bulk packaging. Bulk packaging is typically used for high-volume production runs and offers cost advantages for large quantity orders.

Q: Are both parts currently available?
