Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7-146273-9 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Number of positions: 58
• Number of rows: 2
• Pitch spacing (mating): 0.100" (2.54mm)
• Row spacing (mating): 0.100" (2.54mm)
• Connector type: Header, Breakaway
• Mounting type: Through Hole
• Contact type: Male Pin
• Contact shape: Square

Electrical Compatibility:

• Current rating: 3A
• Operating temperature range: -65°C ~ 105°C
• Contact finish (mating): Gold
• Contact finish (post): Tin
• Contact material: Copper Alloy

Material & Compliance:

• Insulation material: Liquid Crystal Polymer (LCP)
• Material flammability rating: UL94 V-0
• RoHS compliance: RoHS Compliant
• Moisture sensitivity level: 1 (Unlimited)

The primary distinction between the main part and substitute parts lies in termination method and product status. Substitutes must maintain identical mechanical and electrical specifications while accommodating functional termination variations within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 7-146261-9 serves as the active production equivalent to the obsolete 7-146273-9. Both connectors maintain identical mechanical and electrical specifications across all critical parameters including position count, pitch spacing, contact geometry, material composition, and thermal operating range.

The primary distinction is product status: the 7-146273-9 is obsolete while the 7-146261-9 is active. The 7-146261-9 offers superior supply chain availability and long-term support for new designs and legacy system replacements.

Both parts carry RoHS compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility. The termination method differs between kinked pin and standard solder configurations; however, both achieve equivalent solder joint performance in through-hole applications.

For applications requiring the 7-146273-9, the 7-146261-9 provides direct functional substitution with the advantage of active manufacturing status and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 7-146261-9 directly replace the 7-146273-9 in existing designs?

A: Yes. Both connectors share identical mechanical dimensions, pitch spacing, contact geometry, and electrical ratings. The 58-position, 2-row configuration with 0.100" (2.54mm) pitch remains constant. Through-hole mounting compatibility is maintained across both parts.

Q: What is the difference between kinked pin and standard solder termination?

A: The 7-146273-9 features kinked pin termination combined with solder, while the 7-146261-9 uses standard solder termination. Both methods provide equivalent mechanical and electrical connection in through-hole PCB applications. The kinked pin design in the main part provides additional mechanical retention during solder reflow.

Q: Are there compliance or certification differences between these parts?

A: No. Both connectors carry identical RoHS compliance status, UL94 V-0 flammability rating, and moisture sensitivity level 1 (unlimited). Regulatory and environmental specifications are equivalent.

Q: Why is the 7-146273-9 listed as obsolete?

A: The 7-146273-9 has been superseded by the 7-146261-9 in TE Connectivity's active product portfolio. The 7-146261-9 maintains all functional specifications while offering current manufacturing support and improved supply chain availability.

Q: What is the current rating and operating temperature range for these connectors?

A: Both connectors are rated for 3A continuous current and operate across the temperature range of -65°C to 105°C. These specifications apply to all 58 positions in the connector assembly.

Q: Are these connectors suitable for board-to-board and cable applications?

A: Yes. Both the 7-146273-9 and 7-146261-9 are classified as board-to-board or cable style connectors. The unshrouded header design with breakaway capability supports flexible application configurations.

Q: What contact material and finish specifications apply to these connectors?

A: Both connectors use copper alloy contacts with gold plating on mating surfaces (30.0µin thickness) and tin plating on solder posts (100.0µin thickness). Contact shape is square across all 58 positions.
