TE Connectivity Deutsch Connectors 776495-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Deutsch Connectors 776495-3 is an 8-position rectangular connector receptacle housing from the AMPSEAL 16 series. This component is a black thermoplastic, glass-filled receptacle designed for crimp contact termination with a 0.177" (4.50mm) pitch configuration. The part is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the primary part number becomes unavailable, when inventory levels require alternative sourcing, or when design flexibility permits selection from equivalent housing variants within the same connector series and electrical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict electrical and mechanical compatibility. The following parameters must remain identical across all substitute parts:

Critical Substitution Parameters:

Series designation (AMPSEAL 16)
Connector type (Receptacle)
Contact type (Male Pin)
Number of positions (8)
Pitch specification (0.177" / 4.50mm)
Row configuration (2 rows)
Row spacing (0.209" / 5.30mm)
Mounting type (Free Hanging In-Line)
Contact termination method (Crimp)
Fastening mechanism (Locking Ramp)
Insulation material (Thermoplastic, Glass Filled)
Operating temperature range (-40°C ~ 125°C)
Color (Black)

All five substitute part numbers (776495-2, 776495-4, 776538-1, 776538-2, 776538-4) meet these criteria and are therefore electrically and mechanically interchangeable with the primary part 776495-3. The differences between these parts are limited to base product number designation and minor variant coding, which do not affect functional compatibility.

Engineering Selection Recommendations

All five substitute parts are fully qualified alternatives to the primary part 776495-3 based on electrical and mechanical parameters. Selection among these equivalent parts should be based on the following factors:

Compliance and Regulatory Status: All substitute parts maintain ROHS3 compliance and EAR99 export classification. Parts 776495-2, 776538-1, and 776538-2 carry explicit REACH Unaffected status. Parts 776495-4 and 776538-4 show Vendor Undefined REACH status, which does not affect functional equivalence but may require clarification for specific regulatory documentation requirements.

Inventory Availability: Part 776538-1 offers the highest inventory level at 1392 pieces. Parts 776538-4 and 776495-2 provide strong availability at 1240 and 1239 pieces respectively. Part 776495-4 maintains 918 pieces in stock. The primary part 776495-3 has 826 pieces available.

Product Status: All parts maintain Active product status, indicating ongoing manufacturer support and availability.

Base Product Number Variants: Parts designated with base number 776495 (776495-2, 776495-3, 776495-4) and those designated with base number 776538 (776538-1, 776538-2, 776538-4) are functionally equivalent. The base number distinction does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically compatible with 776495-3?

A: Yes. All five substitute parts (776495-2, 776495-4, 776538-1, 776538-2, 776538-4) share identical electrical specifications including connector type, contact type, number of positions, pitch, row configuration, and operating temperature range. They are direct electrical equivalents.

Q: Are all substitute parts mechanically interchangeable with 776495-3?

A: Yes. All substitute parts maintain identical mechanical specifications including mounting type (Free Hanging In-Line), fastening type (Locking Ramp), insulation material (Thermoplastic, Glass Filled), and physical dimensions (pitch 0.177" / 4.50mm, row spacing 0.209" / 5.30mm). They are direct mechanical equivalents.

Q: What is the difference between 776495 and 776538 base product numbers?

A: The base product number distinction (776495 versus 776538) represents variant coding within the AMPSEAL 16 series. This designation does not affect electrical or mechanical compatibility. Both base numbers produce housings with identical functional specifications.

Q: Do all substitute parts require the same contact specifications?

A: Yes. All parts are specified as receptacles with male pin contacts and crimp termination. The note "Contacts Not Included" applies uniformly across all parts. Contact selection must match the 8-position, 0.177" (4.50mm) pitch requirement.

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

A: MSL 1 indicates the lowest moisture sensitivity level, meaning these components have unlimited shelf life and do not require special moisture control during storage or handling. This specification is consistent across all parts.

Q: Are there any REACH or export compliance differences between substitute parts?

A: Parts 776495-2, 776538-1, and 776538-2 carry explicit REACH Unaffected status. Parts 776495-4 and 776538-4 show Vendor Undefined REACH status. All parts maintain EAR99 export classification. For applications requiring specific REACH documentation, parts with explicit REACH Unaffected status may be preferred.

Q: Can I mix substitute parts in the same assembly?

A: Yes. Since all substitute parts are electrically and mechanically equivalent, they can be used interchangeably within the same assembly or application without modification to mating connectors or contact specifications.

Q: Which substitute part offers the best inventory availability?

A: Part 776538-1 provides the highest inventory level at 1392 pieces, followed by 776538-4 at 1240 pieces and 776495-2 at 1239 pieces.
