Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1796607 is determined by strict alignment of the following critical parameters:

Electrical Specifications: Current rating (12A IEC), voltage rating (250V IEC), and contact mating finish (tin) must match exactly
Physical Dimensions: Pitch (0.200"/5.08mm), contact tail length (0.154"/3.90mm), and insulation height (0.472"/12.00mm) must be identical
Mechanical Configuration: 7-position count, vertical orientation, male pin type, and through-hole solder termination are non-negotiable
Housing & Safety: Polyamide (PA) nylon construction, UL94 V-0 flammability rating, and shrouded (4-side) design must be preserved
Compliance: RoHS compliance status must be maintained or upgraded

The substitute part 1796607 meets all these criteria while offering active product status and current availability.

Engineering Selection Recommendations

The Phoenix Contact 1796377 is a direct functional equivalent to the obsolete 1796607. Both components share identical electrical ratings (12A/250V IEC), physical dimensions, and mechanical configuration. The primary distinction is product lifecycle status: the 1796607 is obsolete, while the 1796377 maintains active status with current manufacturing support.

The 1796377 offers enhanced compliance through ROHS3 certification compared to the base RoHS compliance of the 1796607. Both components maintain UL94 V-0 flammability rating and explosion-proof construction with locking ramp features. The series designation differs slightly (COMBICON MSTBV versus COMBICON MSTBVA), reflecting manufacturing evolution within the same product family.

For new designs or component replacement in existing systems, the 1796377 is the appropriate selection due to active product status, current inventory availability (848 pcs), and maintained compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 1796377 be used as a direct replacement for the 1796607 in existing PCB designs?

A: Yes. Both components share identical pitch (5.08mm), contact tail length (3.90mm), insulation height (12.00mm), and through-hole solder termination. PCB footprints are compatible without modification.

Q: What is the difference between the COMBICON MSTBVA and COMBICON MSTBV series designations?

A: Both designations refer to the same product family within Phoenix Contact's COMBICON terminal block line. The series variation reflects manufacturing updates while maintaining electrical and mechanical compatibility.

Q: Are there any compliance differences between the two parts?

A: The 1796377 carries ROHS3 certification, which supersedes the base RoHS compliance of the 1796607. Both maintain UL94 V-0 flammability rating and identical electrical specifications. The upgrade in compliance status presents no compatibility issues.

Q: Why is the 1796607 listed as obsolete?

A: Product obsolescence reflects Phoenix Contact's lifecycle management. The 1796377 represents the current active equivalent within the same product family, offering the same functionality with ongoing manufacturing support.

Q: What is the current inventory status for the substitute part?

A: The 1796377 has 848 pieces in stock as new original inventory, ensuring availability for immediate procurement.

Q: Are the electrical ratings identical between both parts?

A: Yes. Both components are rated for 12A (IEC) and 250V (IEC) with tin contact mating finish, ensuring equivalent performance in circuit applications.
