Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1616200000 is determined by the following critical parameters:

Position Count & Pitch: 9 positions at 0.138" (4.6mm) spacing (non-negotiable for PCB compatibility)
Header Type & Shrouding: Male pins with 4-side shrouding (mechanical and electrical safety requirement)
Mounting Configuration: Vertical through-hole orientation (board layout constraint)
Electrical Ratings: Current and voltage ratings must meet or exceed application requirements
Termination Method: Solder termination (assembly process compatibility)
Material Compliance: UL94 V-0 flammability rating (safety standard requirement)

The TE Connectivity AMP Connectors part number 284516-9 satisfies all critical substitution criteria. Both components share identical position count, pitch, header type, shrouding configuration, mounting style, and termination method. Both meet UL94 V-0 flammability requirements and tin contact mating finish specifications.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 284516-9 is a direct functional substitute for the obsolete Weidmüller 1616200000. Both components meet identical mechanical and electrical interface requirements for 9-position, 4.6mm pitch vertical through-hole terminal block applications.

The TE Connectivity part offers operational advantages: higher UL current rating (11A versus 10A), extended operating temperature range (-40°C to 110°C versus -20°C to 100°C), and active product status ensuring ongoing availability. Both parts maintain UL94 V-0 flammability compliance and tin contact mating finish specifications.

The TE Connectivity 284516-9 is RoHS compliant with MSL rating of 1 (Unlimited), providing additional environmental and handling advantages over the obsolete Weidmüller component.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 284516-9 be used as a direct replacement for the Weidmüller 1616200000 in existing designs?

A: Yes. Both components share identical position count (9), pitch (4.6mm), header type (male pins, 4-side shrouded), mounting orientation (vertical through-hole), and termination method (solder). PCB footprints and assembly processes are compatible.

Q: What are the key differences between these two parts?

A: The primary differences are contact material (Copper Alloy versus Phosphor Bronze), housing material (PBT versus PA66 Nylon 6/6), and operating specifications. The TE part has higher current rating (11A versus 10A), wider temperature range (-40°C to 110°C versus -20°C to 100°C), and is actively manufactured.

Q: Are there any electrical performance differences that would affect circuit operation?

A: No. Both parts meet or exceed the same UL voltage rating (300V) and tin contact mating finish. The TE part's higher current rating (11A) provides additional margin for applications previously limited to 10A.

Q: What is the significance of the different housing materials?

A: Both PBT and PA66 Nylon 6/6 are engineered polymers meeting UL94 V-0 flammability requirements. Material selection affects mechanical properties and environmental resistance, but both are suitable for standard terminal block applications. Specific application requirements (chemical exposure, mechanical stress) should be evaluated if critical.

Q: Why is the Weidmüller part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The TE Connectivity 284516-9 remains in active production, ensuring long-term availability for new designs and ongoing system support.

Q: Are there packaging differences between these parts?

A: The Weidmüller part is listed with unspecified packaging, while the TE Connectivity part is supplied in Bulk packaging. Confirm packaging requirements with your supplier for procurement planning.
