Phoenix Contact 1796445 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1796445 is a 3-position terminal block header with male pins, shrouded design, and 90° right-angle orientation. It features 0.200" (5.08mm) pitch spacing, solder termination, and through-hole mounting. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications.

The COMBICON MSTBA series design provides explosion-proof construction with locking ramp features, suitable for industrial control and power distribution circuits requiring 12A current capacity at 250V.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1796445 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Current rating (12A IEC), voltage rating (250V IEC), and contact material properties must remain unchanged
• Mechanical Compatibility: Position count (3), pitch spacing (5.08mm), header orientation (90° right angle), and contact tail length (4.60mm) must be identical
• Termination and Mounting: Solder termination and through-hole mounting type are non-negotiable for PCB assembly compatibility
• Physical Envelope: Insulation height (8.61mm) and shrouded 4-side design ensure proper mating and safety clearances
• Material and Compliance: Polyamide housing with UL94 V-0 flammability rating and RoHS compliance status

The Phoenix Contact 1795679 meets all substitution criteria as an active-status equivalent within the COMBICON MSTB series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1795679 is the direct active-status equivalent for the obsolete 1796445 model. Both components share identical electrical ratings (12A, 250V), mechanical dimensions, and termination specifications. The 1795679 maintains full compatibility with existing PCB layouts and mating connector designs.

The transition from COMBICON MSTBA to COMBICON MSTB series represents a product line consolidation by Phoenix Contact. The 1795679 carries ROHS3 compliance status, providing enhanced regulatory alignment compared to the legacy RoHS Compliant designation of the 1796445. Both components meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications.

For new designs or component replenishment, the 1795679 is the specified replacement. Existing inventory of 1796445 units remains functionally equivalent for applications already in production, provided no regulatory or compliance updates mandate transition.

Frequently Asked Questions (FAQ)

Q: Can the 1795679 be used as a direct replacement for the 1796445 in existing assemblies?

A: Yes. Both components feature identical electrical ratings (12A, 250V), mechanical envelope (3 positions, 5.08mm pitch, 90° orientation), contact tail length (4.60mm), and solder termination. PCB footprints and mating connector compatibility are preserved.

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

A: The MSTB series represents the current product line. The MSTBA series is obsolete. The 1795679 (MSTB) is the active equivalent of the 1796445 (MSTBA) with no functional or dimensional differences.

Q: Are there packaging differences between these parts?

A: The 1796445 is listed with unspecified packaging, while the 1795679 is supplied in bulk packaging. Verify packaging requirements with your procurement specification before ordering.

Q: Does the ROHS3 compliance of the 1795679 affect compatibility?

A: No. ROHS3 compliance is a regulatory enhancement that does not alter electrical or mechanical performance. The 1795679 is fully compatible with applications designed for the 1796445.

Q: What features distinguish these terminal blocks from standard alternatives?

A: Both components include explosion-proof construction. The 1796445 features a locking ramp, while the 1795679 includes a mating and mounting flange. These design variations do not affect electrical substitution but may influence mechanical integration in specific applications.

Q: Is the 1795679 suitable for new product designs?

A: Yes. The 1795679 is active-status and carries current compliance certifications (ROHS3, UL94 V-0, MSL 1). It is the recommended choice for new designs requiring 3-position, 5.08mm pitch terminal block headers with 90° right-angle orientation and 12A/250V ratings.
