Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 87577-4 rectangular connector header is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (14)
• Number of rows (2)
• Pitch spacing (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Detent Lock)
• Operating temperature range (-65°C ~ 105°C)
• Current rating (3A)
• Flammability rating (UL94 V-0)
• Insulation material (Thermoplastic)
• Contact material (Phosphor Bronze)

The substitute part 5-87577-4 maintains full electrical and mechanical compatibility with the original 87577-4 across all specified parameters. The primary distinction between these parts is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-87577-4 serves as the direct active equivalent to the obsolete 87577-4 rectangular connector header. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, pitch spacing, mounting orientation, and thermal operating range.

The 5-87577-4 is designated as an active product with ROHS3 compliance, whereas the 87577-4 carries obsolete status with RoHS classification listed as not applicable. For new designs and ongoing production requiring this connector type, the 5-87577-4 is the appropriate selection.

The contact finish difference between the parts—Tin-Lead on the 87577-4 versus Tin on the 5-87577-4—does not affect functional compatibility. Both finishes provide equivalent electrical performance and solder joint reliability at the specified current rating of 3A and operating temperature range of -65°C to 105°C.

Packaging configuration differs between the parts: the 87577-4 is supplied in bulk packaging, while the 5-87577-4 is supplied in tray packaging. This distinction affects handling and storage procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 5-87577-4 be used as a direct replacement for the 87577-4 in existing designs?

A: Yes. The 5-87577-4 maintains full electrical and mechanical compatibility with the 87577-4 across all specified parameters. Both connectors feature identical 14-position, 2-row configuration with 0.100" (2.54mm) pitch spacing, through-hole right-angle mounting, shrouded 4-wall construction, and 3A current rating. The parts are functionally interchangeable.

Q: What is the significance of the contact finish difference between these parts?

A: The 87577-4 features Tin-Lead contact finish, while the 5-87577-4 features Tin contact finish. Both finishes provide equivalent electrical conductivity and solder joint reliability at the specified operating parameters. The Tin finish on the 5-87577-4 reflects compliance with modern RoHS3 standards.

Q: Why is the 87577-4 listed as obsolete?

A: The 87577-4 has been superseded by the 5-87577-4, which maintains identical specifications while offering active product status and RoHS3 compliance. TE Connectivity has transitioned production to the 5-87577-4 variant.

Q: Does packaging configuration affect connector performance?

A: No. The difference between bulk packaging (87577-4) and tray packaging (5-87577-4) affects only handling, storage, and logistics procedures. Electrical and mechanical performance remain identical.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 87577-4 and 5-87577-4 operate across the identical temperature range of -65°C to 105°C and maintain the same UL94 V-0 flammability rating.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these connectors be used in applications requiring RoHS compliance?

A: The 5-87577-4 is ROHS3 compliant and is the appropriate selection for applications with RoHS requirements. The 87577-4 carries RoHS status listed as not applicable due to its obsolete designation.
