Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1658043-4 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain identical:

• Connector type and contact configuration (Receptacle, Center Strip Contacts)
• Position count (160 positions)
• Contact pitch (0.031" / 0.80mm)
• Row configuration (2 rows)
• Surface mount mounting type
• Contact finish material and thickness (Gold, Flash)
• Presence of board guide and ground bus features
• Height above board (0.128" / 3.25mm)
• Mated stacking height options
• Moisture sensitivity level (MSL 1)

The substitute part 2-1658043-4 maintains complete parametric equivalence with the main part 1658043-4 across all specified dimensions, electrical characteristics, and mechanical features. Both parts belong to the MICTOR SB series and share the same base product number (1658043), differing only in their specific part number designation.

Parameter Comparison

Engineering Selection Recommendations

Both the 1658043-4 and 2-1658043-4 are classified as Active products and are suitable for direct substitution in applications requiring 160-position rectangular connectors with the specified electrical and mechanical characteristics.

The primary distinction between these parts relates to compliance certifications. The 2-1658043-4 carries ROHS3 Compliant status, making it the preferred selection for applications subject to Restriction of Hazardous Substances regulations. The 1658043-4 lists RoHS status as Not applicable.

Both parts maintain identical parametric specifications across all critical dimensions, contact configurations, and mounting characteristics. Selection between these parts should be based on regulatory compliance requirements applicable to the end application and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Are the 1658043-4 and 2-1658043-4 electrically interchangeable?

A: Yes. Both parts are electrically equivalent, featuring identical 160-position configurations, 0.031" pitch, gold contact finish, and center strip contact design. They perform identically in circuit applications.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 2-1658043-4 is ROHS3 Compliant, while the 1658043-4 lists RoHS status as Not applicable. All other electrical and mechanical parameters are identical.

Q: Can I use these connectors interchangeably on the same PCB?

A: Yes. Both parts share identical mounting specifications, including surface mount type, height above board (0.128"), and board guide features. They occupy the same footprint and require no PCB redesign for substitution.

Q: What does the 0.031" pitch specification mean?

A: The pitch of 0.031" (0.80mm) defines the center-to-center distance between adjacent contact positions. Both parts maintain this identical spacing across all 160 positions arranged in 2 rows.

Q: Are there any stacking height limitations?

A: Both parts support mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, 22mm, 25mm, and 30mm. Selection of stacking height depends on application requirements and mating connector specifications.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. These connectors have unlimited shelf life under normal storage conditions and do not require special moisture control measures during handling or storage.

Q: Are both parts available in the same packaging format?

A: Yes. Both the 1658043-4 and 2-1658043-4 are supplied in Tray packaging, suitable for automated assembly processes and standard component handling procedures.
