Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1811035 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (IEC: 12A minimum), voltage rating, and contact material must support equivalent or superior performance
• Mechanical Compatibility: 4-position configuration, 0.197" (5.00mm) pitch, vertical orientation, through-hole mounting, and shrouded (4-side) design
• Termination Method: Solder termination required for PCB integration
• Compliance: RoHS compliance and MSL rating for manufacturing process compatibility
• Contact Interface: Tin mating finish for reliable connector mating

The substitute part Phoenix Contact 1837271 meets all critical substitution criteria while offering active product status and enhanced electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1837271 (CCVA 2,5/ 4-G P20 THR R56) is the qualified substitute for the obsolete 1811035 (MSTBVA 2,5/ 4-G THT R56). Selection is based on the following engineering criteria:

Electrical Equivalence: Both parts maintain 12A IEC current rating and identical pitch (5.00mm) and position configuration. The 1837271 provides additional electrical specifications (320V IEC, 16A UL, 300V UL) not documented for the main part, representing enhanced capability.

Mechanical Compatibility: Both components feature identical 4-position shrouded (4-side) male pin headers with vertical through-hole mounting and solder termination. The contact tail length differs (3.90mm vs. 2.00mm) and insulation height differs (13.00mm vs. 12.00mm), requiring PCB layout verification for new designs.

Compliance and Certifications: Both parts are RoHS compliant with MSL 1 rating. The 1837271 includes UL94 V-0 material flammability rating and specified operating temperature range (-40°C ~ 100°C), providing additional compliance documentation.

Product Status: The 1837271 maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete 1811035.

Frequently Asked Questions (FAQ)

Q: Can the 1837271 directly replace the 1811035 in existing designs?

A: Mechanical and electrical compatibility is established for the core terminal block function. However, the differences in contact tail length (3.90mm vs. 2.00mm) and insulation height (13.00mm vs. 12.00mm) require verification against PCB pad layouts and clearance requirements. Consult the detailed mechanical drawings for both parts before implementation.

Q: What is the significance of the different series designations (MSTBVA vs. CCVA)?

A: The MSTBVA and CCVA series represent different product lines within Phoenix Contact's COMBICON terminal block family. Both series maintain compatible electrical and mechanical specifications for this 4-position, 5.00mm pitch configuration, but the CCVA series (1837271) represents the current active product line.

Q: Are there packaging differences between these parts?

A: The 1811035 packaging is not specified in the documentation. The 1837271 is supplied in Tape & Reel (TR) packaging, which is standard for high-volume manufacturing and automated assembly processes.

Q: What materials are used in the 1837271 compared to the 1811035?

A: The 1837271 specifies Copper Alloy contacts and Liquid Crystal Polymer (LCP) housing material. The 1811035 material specifications are not documented. The LCP housing in the 1837271 provides UL94 V-0 flammability rating and enhanced thermal stability.

Q: Is the 1837271 suitable for the same operating temperature range as the 1811035?

A: The 1811035 operating temperature is not specified. The 1837271 operates across -40°C to 100°C, which covers standard industrial and commercial temperature ranges. Verify application requirements against this specification.
