Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for Phoenix Contact 3190551 is determined by strict equivalence across the following critical parameters:

• Series Compatibility: Part must belong to COMBICON MSTBC series
• Contact Configuration: Socket type with crimp termination method
• Contact Finish: Tin plating specification
• Base Product Number: MSTBC-MT designation
• Electrical & Mechanical Specifications: Identical contact geometry and performance characteristics
• Compliance Status: RoHS and REACH compliance maintained

The identified substitute part 3190658 maintains complete functional and mechanical equivalence to 3190551. The sole difference between these parts is packaging format: 3190551 is supplied in Bulk packaging, while 3190658 is supplied in Tape & Reel (TR) format. Both parts share identical electrical performance, contact specifications, and compliance certifications, making them directly interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

Both Phoenix Contact 3190551 and 3190658 are active production parts with full regulatory compliance. Selection between these parts should be based on packaging and supply chain requirements:

3190551 (Bulk Packaging): Suitable for applications requiring flexible quantity procurement, manual assembly operations, or inventory management where individual component handling is standard practice.

3190658 (Tape & Reel Packaging): Suitable for high-volume automated assembly processes, pick-and-place machine compatibility, and supply chains optimized for continuous reel-based component feeding.

Both parts maintain identical electrical performance, mechanical compatibility, and compliance certifications. The choice between them is a procurement and manufacturing process decision, not a technical performance decision.

Frequently Asked Questions (FAQ)

Q: Are Phoenix Contact 3190551 and 3190658 electrically identical? A: Yes. Both parts are identical socket crimp contacts with tin finish, belonging to the COMBICON MSTBC series. They share the same base product number (MSTBC-MT) and all electrical specifications.
