Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1757196 is determined by the following critical parameters:

• Number of Positions: Must remain 5 positions to maintain connector compatibility
• Pitch Specification: Must maintain 0.200" (5.08mm) pitch for PCB footprint alignment
• Series Compatibility: COMBICON MSTB series ensures mechanical and electrical compatibility
• Color Coding: Green housing maintains visual identification consistency

The substitute part Phoenix Contact 1876631 satisfies these core requirements while introducing enhanced specifications including right-angle orientation, shrouded design, and active product status with full electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1876631 serves as the primary substitute for the obsolete 1757196. Selection is justified on the following basis:

Product Status: The 1876631 maintains active product status, ensuring continued availability and manufacturer support, whereas the 1757196 is obsolete.

Compliance: Both parts maintain equivalent RoHS compliance levels. The 1876631 carries ROHS3 Compliant status with additional REACH Unaffected designation, providing enhanced regulatory documentation.

Core Specifications: Both parts maintain identical pitch (0.200"/5.08mm), position count (5), and series designation (COMBICON MSTB), ensuring mechanical and electrical compatibility at the connector interface level.

Enhanced Features: The 1876631 introduces right-angle (90°) orientation, shrouded design (4-side), and specified electrical ratings (12A IEC / 15A UL), providing additional design flexibility for applications requiring through-hole mounting and enhanced pin protection.

Frequently Asked Questions (FAQ)

Q: Can the 1876631 directly replace the 1757196 in existing designs?

A: Direct replacement depends on mounting orientation requirements. The 1757196 is a straight header, while the 1876631 is a 90° right-angle header. PCB layout and connector mating orientation must be evaluated. Both maintain identical pitch and position count, ensuring electrical compatibility at the connector interface.

Q: What is the significance of the shrouded (4 Side) design in the 1876631?

A: The shrouded design provides mechanical protection to the male pins during handling and mating operations. This feature is not present in the 1757196 and represents an enhancement in the substitute part.

Q: Are there any electrical rating differences between these parts?

A: The 1757196 does not specify electrical ratings in the provided data. The 1876631 specifies 12A at 400V (IEC) and 15A at 300V (UL). These ratings apply to the 1876631 and should be verified against application requirements.

Q: Why is the 1757196 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 1876631, as an active product within the same COMBICON MSTB series, provides continuity for applications requiring 5-position, 5.08mm pitch terminal block headers.

Q: Are packaging considerations important for substitution?

A: The 1757196 packaging is listed as unspecified, while the 1876631 is supplied in Bulk packaging. Verify bulk packaging specifications against procurement requirements for your application.
