Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1796539 is determined by strict alignment of the following critical parameters:

• Position Count and Pitch: 12 positions at 0.200" (5.08mm) spacing
• Connector Type and Gender: Header with male pins, shrouded (4-side) design
• Orientation and Mounting: 90° right-angle through-hole configuration
• Electrical Ratings: 12A current and 250V voltage per IEC standards
• Physical Dimensions: Contact tail length of 0.138" (4.60mm) and insulation height of 0.339" (8.61mm)
• Material and Compliance: Polyamide housing, UL94 V-0 flammability rating, and RoHS compliance

The substitute part Phoenix Contact 1796539 meets all these criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1795763 is a direct functional equivalent to the 1796539. Both components share identical electrical ratings (12A, 250V), mechanical dimensions, and material specifications. The primary distinction is product status: the 1796539 is obsolete while the 1795763 maintains active status with higher inventory availability (1183 pcs vs. 801 pcs).

Both parts carry UL94 V-0 flammability certification and RoHS compliance, meeting equivalent safety and environmental standards. The 1795763 belongs to the COMBICON MSTB series compared to the MSTBA series of the original part, representing a product line evolution within Phoenix Contact's terminal block portfolio.

For new designs and ongoing system support, the 1795763 is the appropriate selection due to its active product status and sustained manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the 1795763 be used as a direct replacement for the 1796539 in existing assemblies?

A: Yes. Both components are identical in electrical ratings (12A, 250V), mechanical dimensions (contact tail length 0.138", insulation height 0.339"), pitch spacing (5.08mm), and connector configuration (12-position male pin header, shrouded, right-angle through-hole). Physical and functional compatibility is complete.

Q: What is the difference between the COMBICON MSTBA and COMBICON MSTB series?

A: The MSTB series represents the current product line evolution. The 1795763 (MSTB series) is the active equivalent to the 1796539 (MSTBA series). Both maintain identical specifications for the 12-position 5.08mm pitch header configuration.

Q: Are there any packaging differences between these parts?

A: The 1796539 is supplied with unspecified packaging, while the 1795763 is supplied in bulk packaging. Both are new original stock components with identical electrical and mechanical properties.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1796539 and 1795763 are UL94 V-0 rated, RoHS compliant, classified as MSL 1 (Unlimited), and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) designations.

Q: Why should I select the 1795763 over the 1796539?

A: The 1795763 is the recommended selection because it maintains active product status with sustained manufacturing support and higher inventory availability. The 1796539 is obsolete and subject to discontinuation of supply.
