TE Connectivity Deutsch Connectors 776487-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Deutsch Connectors 776487-4 is a 4-position rectangular connector plug housing from the AMPSEAL 16 series. This component is classified as an active product and serves as a housing for female socket contacts in crimp-terminated applications. The connector features a 0.177" (4.50mm) pitch configuration with a 2-row layout and latch lock fastening mechanism.

Substitute parts are identified when equivalent rectangular connector housings share identical electrical and mechanical specifications, including connector type, contact configuration, pitch, row spacing, mounting characteristics, and operating parameters. Identifying equivalent alternatives ensures design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 776487-4 are identified based on parametric equivalence within the rectangular connector category. The substitution logic is based on the following critical parameters that must remain identical:

• Connector Type: Plug
• Contact Type: Female Socket
• Number of Positions: 4
• Pitch: 0.177" (4.50mm)
• Number of Rows: 2
• Row Spacing: 0.209" (5.30mm)
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Insulation Material: Thermoplastic, Glass Filled
• Operating Temperature Range: -40°C ~ 125°C
• Series: AMPSEAL 16

The identified substitute parts 776487-1 and 776487-3 maintain all critical electrical and mechanical parameters. These parts are functionally interchangeable within applications requiring 4-position AMPSEAL 16 plug housings with the specified pitch and row configuration.

Parameter Comparison

Engineering Selection Recommendations

All three parts—776487-4, 776487-1, and 776487-3—are active products manufactured by TE Connectivity Deutsch Connectors and maintain full ROHS3 compliance. Each part carries identical electrical and mechanical specifications, making them functionally equivalent for rectangular connector applications requiring 4-position AMPSEAL 16 plug housings.

Selection between these parts should be based on availability and inventory status. The 776487-3 variant currently maintains the highest inventory level at 1291 pieces, followed by 776487-1 at 1101 pieces, and 776487-4 at 954 pieces. All parts are classified as new original stock.

Compliance certifications are consistent across all three parts. The ECCN classification of EAR99 and HTSUS code 8536.69.8000 apply uniformly. REACH status differs between the main part (Vendor Undefined) and substitute parts (REACH Unaffected), with substitute parts providing explicit compliance documentation.

Frequently Asked Questions (FAQ)

Q: Are 776487-1 and 776487-3 direct replacements for 776487-4?

A: Yes. These parts are parametric equivalents sharing identical connector type, contact configuration, pitch, row spacing, mounting characteristics, termination method, and operating temperature range. They are functionally interchangeable in applications requiring 4-position AMPSEAL 16 plug housings.

Q: What determines whether a rectangular connector can substitute for the 776487-4?

A: Substitution is determined by matching all critical parameters: connector type (plug), contact type (female socket), number of positions (4), pitch (0.177"/4.50mm), row configuration (2 rows with 0.209"/5.30mm spacing), mounting type (free hanging in-line), termination method (crimp), fastening mechanism (latch lock), and operating temperature range (-40°C to 125°C).

Q: Do these parts require different contact specifications?

A: No. All three parts are supplied as housings without contacts included. Contact selection and specifications remain independent of the housing variant selected.

Q: Are there differences in compliance or regulatory status between these parts?

A: All parts maintain ROHS3 compliance, MSL 1 rating, and EAR99 ECCN classification. The substitute parts (776487-1 and 776487-3) carry explicit REACH Unaffected status, while the main part lists REACH status as Vendor Undefined.

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

A: Yes. The identical pitch, row spacing, mounting type, and fastening mechanism ensure mechanical and electrical compatibility. No design modifications are required when substituting between these parts.

Q: What is the significance of the different part numbers if the specifications are identical?

A: The different suffixes (-1, -3, -4) represent distinct manufacturing or inventory tracking designations within the TE Connectivity Deutsch Connectors product line. The parametric equivalence ensures functional interchangeability despite the different part numbers.
