Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1776142-3 is determined by the following critical parameters that must remain consistent across equivalent parts:

Core Compatibility Parameters:

• Number of Positions: 3
• Pitch: 0.197" (5.00mm)
• Header Orientation: Vertical
• Mounting Type: Through Hole
• Termination Style: Solder
• Material Flammability Rating: UL94 V-0
• Voltage - UL: 300 V

Allowable Variation Parameters:

• Shrouding Configuration: 2 Side (main part) to 4 Side (substitute parts) — enhanced shrouding provides additional mechanical protection and does not compromise electrical function
• Current Rating: 15 A (main part) to 12 A or 16 A (substitute parts) — substitute parts with equal or higher current ratings are acceptable
• Housing Material: Polyamide (PA), Nylon to Polybutylene Terephthalate (PBT) — both materials meet UL94 V-0 flammability requirements
• Contact Tail Length: 0.138" (3.50mm) to 0.154" (3.90mm) — minor dimensional variation within acceptable solder joint parameters
• RoHS Status: RoHS Compliant to ROHS3 Compliant — both represent current compliance standards

The substitute parts Phoenix Contact 1776896 and Phoenix Contact 1924428 maintain all core compatibility parameters while offering enhanced electrical ratings and improved mechanical shrouding.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1776142-3 (Original Part)

Select this part when the original design specification requires 2-side shrouding configuration and 15 A UL current rating. This component maintains Active product status and RoHS Compliant certification. The Polyamide (PA), Nylon housing material is suitable for standard industrial applications within the specified operating temperature range of -40°C to 110°C.

Phoenix Contact 1776896 (Substitute Option)

This part is suitable for applications where enhanced 4-side shrouding is beneficial for mechanical protection and where the 12 A UL current rating meets application requirements. The COMBICON MSTBV series provides ROHS3 Compliant status and Polybutylene Terephthalate (PBT) housing material. The slightly longer contact tail length (0.154" versus 0.138") accommodates standard PCB solder joint specifications. This substitute is appropriate when inventory of the original part is unavailable and the lower current rating does not constrain the application.

Phoenix Contact 1924428 (Substitute Option)

This part is suitable for applications requiring enhanced electrical performance with 16 A UL current rating and 630 V IEC voltage rating. The 4-side shrouding provides superior mechanical protection compared to the original 2-side configuration. The COMBICON MSTBV series offers ROHS3 Compliant status and Polyamide (PA), Nylon housing material matching the original part's material composition. The contact tail length of 0.154" is compatible with standard through-hole PCB assembly processes. This substitute is the preferred option when higher current capacity is required or when the enhanced shrouding design improves mechanical reliability for the application.

Both substitute parts maintain compliance with UL94 V-0 flammability requirements, 300 V UL voltage rating, and MSL 1 moisture sensitivity classification. All three parts share identical pitch spacing, vertical orientation, and solder termination style, ensuring direct functional equivalence in circuit board layout and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1776896 or 1924428 be used as direct replacements for TE Connectivity 1776142-3 on existing PCB designs?

A: Yes, both Phoenix Contact parts are direct functional replacements. The 3-position, 5.00mm pitch vertical through-hole configuration is identical. The slightly longer contact tail length (0.154" versus 0.138") is within acceptable solder joint parameters for standard PCB assembly. The enhanced 4-side shrouding does not interfere with standard board layouts designed for 2-side shrouded headers.

Q: What is the difference between 2-side and 4-side shrouding?

A: The TE Connectivity 1776142-3 features shrouding on two opposing sides, while both Phoenix Contact substitutes feature shrouding on all four sides. Four-side shrouding provides enhanced mechanical protection and improved mating force consistency. Both configurations maintain identical electrical performance and pitch spacing.

Q: Are there current rating differences between the three parts?

A: Yes. The TE Connectivity 1776142-3 is rated for 15 A UL. The Phoenix Contact 1776896 is rated for 12 A UL, while the Phoenix Contact 1924428 is rated for 16 A UL. For applications requiring 15 A operation, the Phoenix Contact 1924428 with 16 A rating is the appropriate substitute. The 1776896 with 12 A rating is suitable only for applications requiring 12 A or less.

Q: Do the substitute parts have different housing materials?

A: The TE Connectivity 1776142-3 uses Polyamide (PA), Nylon housing. The Phoenix Contact 1776896 uses Polybutylene Terephthalate (PBT) housing, while the Phoenix Contact 1924428 uses Polyamide (PA), Nylon housing matching the original. Both materials meet UL94 V-0 flammability requirements. PBT offers enhanced chemical resistance, while Polyamide provides cost efficiency.

Q: Are all three parts RoHS compliant?

A: Yes. The TE Connectivity 1776142-3 is RoHS Compliant. Both Phoenix Contact parts are ROHS3 Compliant, representing the current RoHS compliance standard. Both compliance levels are acceptable for modern electronic applications.

Q: What is the operating temperature range for the substitute parts?

A: The TE Connectivity 1776142-3 specifies -40°C to 110°C operating temperature. The Phoenix Contact substitute parts do not specify an operating temperature range in the provided data. For applications with critical temperature requirements, the original TE Connectivity part with documented temperature specifications is recommended.

Q: Can these parts be used interchangeably in high-voltage applications?

A: All three parts are rated for 300 V UL voltage. The Phoenix Contact 1924428 additionally supports 630 V IEC voltage rating. For applications requiring voltage ratings above 300 V, the Phoenix Contact 1924428 is the appropriate selection.

Q: What is the contact tail length difference, and does it affect PCB design?

A: The TE Connectivity 1776142-3 has a contact tail length of 0.138" (3.50mm), while both Phoenix Contact substitutes have 0.154" (3.90mm) tail length. This 0.016" (0.40mm) difference is within standard PCB through-hole tolerance specifications and does not require PCB redesign. Standard solder joint formation accommodates both dimensions.
