Substitute Part Grouping Explanation

Substitution eligibility for the 145166-4 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part 5145166-4 qualifies as a direct equivalent based on the following criteria:

Electrical Parameters (Must Match Exactly):

• 184 position count
• 0.050" (1.27mm) pitch spacing
• PCI 5V 64-bit card type specification
• Female gender configuration
• Dual read-out functionality
• Gold contact finish with 30.0µin (0.76µm) thickness
• Phosphor bronze contact material

Mechanical Parameters (Must Match Exactly):

• 2-row configuration with 49, 11, 32 position distribution
• 0.062" (1.57mm) card thickness accommodation
• Through-hole mounting type
• Solder termination with staggered contact arrangement
• Board guide feature inclusion
• Natural color thermoplastic insulation material

The substitute part 5145166-4 maintains identical electrical and mechanical specifications to the main part 145166-4, with the primary distinction being packaging format (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5145166-4 provides complete functional and mechanical equivalence to the 145166-4 across all electrical and physical specifications. Selection between these parts is determined by compliance and packaging requirements:

Select 145166-4 when:

• RoHS non-compliant applications are acceptable
• Standard packaging format is required for inventory management
• Legacy system compatibility is specified

Select 5145166-4 when:

• RoHS compliance is mandated by design specifications or regulatory requirements
• Bulk packaging format aligns with procurement and assembly processes
• Supply chain flexibility requires access to RoHS-compliant alternatives

Both parts maintain identical electrical performance, mechanical compatibility, and physical dimensions. The 5145166-4 represents the RoHS-compliant variant of the same connector design within the Standard Edge .050 series. Current inventory availability supports either selection without lead-time impact.

Frequently Asked Questions (FAQ)

Q: Are the 145166-4 and 5145166-4 electrically interchangeable?

A: Yes. Both connectors provide identical electrical specifications including 184-position capacity, 0.050" pitch, PCI 5V 64-bit support, gold contact finish, and dual read-out configuration. They function identically in circuit applications.

Q: What is the primary difference between these two parts?

A: The primary differences are RoHS compliance status and packaging format. The 5145166-4 is RoHS compliant and supplied in bulk packaging, while the 145166-4 is RoHS non-compliant with standard packaging. All electrical and mechanical parameters are identical.

Q: Can I substitute 5145166-4 for 145166-4 in existing designs?

A: Yes, provided that RoHS compliance does not conflict with existing design specifications. The 5145166-4 maintains complete mechanical and electrical compatibility with the 145166-4 across all functional parameters.

Q: Does packaging format affect connector performance?

A: No. Packaging format (standard versus bulk) does not affect connector electrical performance, mechanical fit, or reliability. Packaging selection is determined by procurement and assembly workflow requirements.

Q: Are both parts suitable for through-hole PCB assembly?

A: Yes. Both the 145166-4 and 5145166-4 are designed for through-hole solder termination with staggered contact arrangement and board guide features supporting standard PCB assembly processes.

Q: What card thickness do these connectors accommodate?

A: Both connectors are designed to accommodate 0.062" (1.57mm) card thickness, consistent with PCI 5V 64-bit specification requirements.

Q: Is there a lead-time difference between these substitute parts?

A: Both parts maintain active product status with current inventory availability. No lead-time advantage exists between the two options based on provided inventory data.
