Key Parameters

Substitute Part Grouping Explanation

All substitute parts listed maintain identical electrical and mechanical parameters with the main part 776428-2. Substitution is based strictly on the following key parameters:

• Connector Type: Receptacle
• Contact Type: Male Pin
• Number of Positions: 2
• Pitch: 0.177" (4.50mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Locking Ramp
• Color: Black
• Insulation Material: Thermoplastic, Glass Filled
• Operating Temperature Range: -40°C ~ 125°C
• Series: AMPSEAL 16
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

All substitute parts are manufactured by TE Connectivity Deutsch Connectors and are classified as active products. The substitutes are grouped into two base product families: 776428 series (776428-1, 776428-3) and 776534 series (776534-1, 776534-3, 776534-4). These base product families share identical functional specifications and are interchangeable within the AMPSEAL 16 connector ecosystem.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are classified as active products manufactured by TE Connectivity Deutsch Connectors and maintain ROHS3 compliance. The following factors support substitution decisions:

Product Status: All parts, including the main part 776428-2 and all substitutes (776428-1, 776428-3, 776534-1, 776534-3, 776534-4), are active products. This ensures continued availability and manufacturing support.

Regulatory Compliance: All parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Functional Equivalence: The substitute parts maintain identical electrical and mechanical specifications across all critical parameters: connector type, contact configuration, pitch, mounting method, termination type, and operating temperature range.

Inventory Availability: Substitute parts demonstrate varying inventory levels. Part 776534-1 shows the highest availability at 888,100 units, while 776428-3 shows 686 units. Selection should consider both immediate availability requirements and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can 776428-1, 776428-3, 776534-1, 776534-3, and 776534-4 be used interchangeably with 776428-2?

A: Yes. All substitute parts maintain identical electrical and mechanical specifications including connector type, position count, pitch, mounting configuration, contact termination method, and operating temperature range. Direct substitution is supported within the AMPSEAL 16 connector family.

Q: What is the difference between the 776428 series and 776534 series?

A: Both series share identical functional specifications for the 2-position, 4.50mm pitch receptacle housing configuration. The series designation reflects different base product families within TE Connectivity's AMPSEAL 16 connector line. Selection between series is based on availability and supply chain requirements rather than electrical or mechanical differences.

Q: Are contacts included with these connector housings?

A: No. All parts in this family are housings only. Male pin contacts must be sourced separately and crimped into the housing according to TE Connectivity specifications.

Q: What is the significance of the MSL rating of 1 (Unlimited)?

A: MSL 1 indicates unlimited shelf life without moisture sensitivity constraints. These parts do not require special desiccant packaging or controlled storage conditions and can be stored under standard industrial conditions.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed, including the main part 776428-2 and all substitutes, are ROHS3 compliant. This ensures compliance with European Union Restriction of Hazardous Substances regulations.

Q: Can I mix connector housings from different part numbers in a single assembly?

A: Yes. Since all parts maintain identical specifications, housings from different part numbers can be used together in applications requiring multiple 2-position AMPSEAL 16 receptacle housings.

Q: What mounting configurations are supported?

A: All parts are configured for free-hanging, in-line mounting. This mounting type is suitable for applications where the connector is mounted directly to a cable or harness without additional panel or bracket support.
