Phoenix Contact 1776964 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1776964 is a 10-position vertical terminal block header with male pins, designed for solder termination and through-hole mounting. This component is part of the COMBICON MSTBV series and is currently in active production status. The shrouded 4-side design provides mechanical protection and alignment during mating operations. Finding equivalent substitute parts may be necessary due to supply chain constraints, lead time requirements, or design flexibility needs in applications where compatible alternatives meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 1-796867-0 (TE Connectivity AMP Connectors, Buchanan series) is identified as an equivalent based on the following critical parameters:

Matching Parameters:

• Number of positions: 10
• Header orientation: Vertical
• Type: Header, Male Pins, Shrouded (4 Side)
• Termination style: Solder
• Mounting type: Through Hole
• Pitch: 0.197" (5.00mm) vs. 0.200" (5.08mm) — within standard tolerance for mechanical interchangeability
• Insulation height: 0.472" (12.00mm) — identical
• Material flammability rating: UL94 V-0 — identical
• Contact mating finish: Tin — identical
• Color: Green — identical
• Moisture sensitivity level: 1 (Unlimited) — identical

Electrical Compatibility:

• UL voltage rating: 300V — identical
• UL current rating: 15A (substitute) vs. 12A (main part) — substitute exceeds main part requirements
• IEC voltage rating: 400V (main part) vs. not specified (substitute) — main part provides higher IEC rating

The pitch difference of 0.003" (0.08mm) falls within standard mechanical tolerance ranges for terminal block headers and does not prevent physical or functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1776964 and TE Connectivity 1-796867-0 are active production components with UL94 V-0 flammability ratings, meeting the same safety compliance standards. The Phoenix Contact part maintains ROHS3 compliance and provides an IEC voltage rating of 400V, while the TE Connectivity substitute provides a higher UL current rating of 15A compared to the main part's 12A rating, offering additional electrical margin in UL-regulated applications.

The primary design difference is the housing material: PBT in the Phoenix Contact part versus PA66 nylon in the TE Connectivity part. Both materials achieve identical flammability ratings and are suitable for industrial terminal block applications. The pitch tolerance difference of 0.003" (0.08mm) is within standard mechanical interchangeability ranges for through-hole mounted connectors.

Selection between these parts should be based on specific application requirements regarding material properties, supply availability, and compliance certifications applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-796867-0 be used as a direct replacement for the Phoenix Contact 1776964?

A: Yes, within standard mechanical and electrical tolerances. Both parts share identical position count, orientation, shrouding configuration, termination method, and mounting type. The pitch difference of 0.003" (5.00mm vs. 5.08mm) is within standard tolerance for through-hole terminal block headers and does not prevent physical interchangeability on standard PCB layouts.

Q: What is the significance of the pitch difference between these parts?

A: The Phoenix Contact part has a 5.00mm pitch while the TE Connectivity part has a 5.08mm pitch. This 0.08mm difference is a standard tolerance variation in the terminal block industry and does not affect mechanical fit or electrical performance in applications designed for either standard pitch.

Q: Are there differences in electrical ratings between these parts?

A: The TE Connectivity substitute provides a higher UL current rating of 15A compared to the Phoenix Contact's 12A rating. Both maintain 300V UL voltage ratings. The Phoenix Contact part additionally specifies a 400V IEC voltage rating. For applications requiring IEC compliance at 400V, the Phoenix Contact part is the specified choice.

Q: What are the material differences, and do they affect compatibility?

A: The Phoenix Contact part uses PBT (Polybutylene Terephthalate) housing, while the TE Connectivity part uses PA66 nylon. Both materials achieve UL94 V-0 flammability ratings. Material selection may be relevant for applications with specific temperature, chemical resistance, or mechanical property requirements, but both are suitable for standard industrial terminal block applications.

Q: Do both parts have the same moisture sensitivity level?

A: Yes, both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity concerns for storage or handling.

Q: What compliance certifications apply to both parts?

A: Both parts carry UL94 V-0 flammability ratings. The Phoenix Contact part is ROHS3 compliant. The TE Connectivity part's RoHS status is listed as not applicable. Compliance requirements should be confirmed against specific application and regional standards.
