Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 787177-1 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Connector Configuration: D-Sub connector style with 15 positions arranged in 2 rows, shell size 2 (DA, A) layout, and plug configuration with male pins.

Termination and Mounting: Press-fit termination method with through-hole mounting capability to ensure compatibility with existing printed circuit board designs.

Physical and Material Specifications: Steel shell with tin plating, gold-plated contacts at 30.0µin thickness, polyamide dielectric material, and copper alloy contact material.

Environmental and Compliance Ratings: Operating temperature range of -55°C to 105°C, UL94 V-0 flammability rating, and moisture sensitivity level 1 (unlimited).

Mechanical Interface: Mating side female screwlock feature with 4-40 specification for secure connector engagement.

The substitute part 5787177-1 meets all these criteria and is classified as an active product, providing a direct functional and physical replacement for the obsolete 787177-1.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5787177-1 serves as the direct substitute for the obsolete 787177-1. Both connectors are functionally and mechanically identical across all specified parameters, ensuring drop-in compatibility in existing applications.

Product Status Consideration: The 787177-1 is classified as obsolete, while the 5787177-1 is an active product. Selection of the active substitute ensures continued availability and supply chain reliability for new production runs and replacement requirements.

Compliance Status: The 5787177-1 achieves ROHS3 compliance, whereas the 787177-1 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the 5787177-1 is the appropriate selection.

Packaging Consideration: The 5787177-1 is supplied in bulk packaging, which may differ from the original part's packaging configuration. Bulk packaging is suitable for high-volume manufacturing environments and reduces per-unit cost.

Both parts maintain identical electrical and mechanical specifications, including the AMPLIMITE HD-20 series designation, 15-position configuration, press-fit termination, and UL94 V-0 flammability rating. The substitution presents no functional degradation or performance compromise.

Frequently Asked Questions (FAQ)

Q: Can the 5787177-1 be used as a direct replacement for the 787177-1 in existing designs?

A: Yes. The 5787177-1 is electrically and mechanically identical to the 787177-1 across all specified parameters, including connector configuration, termination method, shell material, contact specifications, and operating temperature range. No design modifications are required.

Q: What is the difference between the 787177-1 and 5787177-1?

A: The primary differences are product status and regulatory compliance. The 787177-1 is obsolete and RoHS non-compliant, while the 5787177-1 is an active product with ROHS3 compliance. All electrical and mechanical specifications are identical.

Q: Why is the 787177-1 listed as obsolete?

A: Obsolescence indicates that the manufacturer has discontinued production of this part number. The 5787177-1 is the active equivalent that replaces it in the product line.

Q: Does the packaging difference between the two parts affect compatibility?

A: No. Packaging differences do not affect connector compatibility or performance. The 5787177-1 is supplied in bulk packaging, which is standard for high-volume applications. The connector itself maintains identical form, fit, and function.

Q: Are there any environmental or temperature limitations that differ between these parts?

A: No. Both connectors operate across the identical temperature range of -55°C to 105°C and maintain the same UL94 V-0 flammability rating and moisture sensitivity level 1 specification.

Q: Is RoHS compliance a critical factor for selecting the 5787177-1?

A: RoHS compliance becomes critical only if your application, customer requirements, or regional regulations mandate it. The 5787177-1 achieves ROHS3 compliance, making it suitable for regulated environments. The 787177-1 does not meet RoHS requirements.

Q: Can both parts be used interchangeably in the same circuit board design?

A: Yes. Both parts are mechanically and electrically interchangeable. They share identical pin configurations, mounting specifications, and electrical characteristics, allowing seamless substitution without PCB redesign.
