Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 555149-1 with the active equivalent 5555149-1 is based on strict electrical and mechanical parameter alignment. Both connectors share identical core specifications: 50-position configuration, 2-row arrangement, through-hole right-angle solder termination, outer shroud contact design, gold contact finish at 30.0µin thickness, and 4-40 housing/shell flange feature. Both operate within the CHAMP .085 series and maintain MSL 1 (Unlimited) moisture sensitivity classification.

The primary differentiators between these parts are product status (obsolete versus active), packaging format (unspecified versus tray), and compliance certifications. The substitute part 5555149-1 includes an additional Board Lock feature and carries ROHS3 compliance, whereas the original part is RoHS non-compliant. These differences do not affect functional or mechanical compatibility in applications requiring the specified connector parameters.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5555149-1 serves as the direct active equivalent to the obsolete 555149-1. Selection of the substitute part is appropriate for all applications requiring a 50-position D-Sub receptacle connector with through-hole right-angle solder termination and outer shroud contact design.

For applications subject to RoHS3 compliance requirements, the 5555149-1 is the mandated selection. The original 555149-1, classified as RoHS non-compliant, is unsuitable for new designs or production environments with regulatory compliance obligations.

The substitute part incorporates an additional Board Lock feature not present in the original specification. This enhancement provides increased mechanical retention without altering electrical performance or mechanical fit characteristics. The tray packaging of the substitute part supports automated assembly workflows and inventory management practices.

Both parts maintain identical electrical and mechanical parameters across all critical specifications: connector geometry, contact configuration, termination method, contact finish, and moisture sensitivity classification. Interchangeability is confirmed for direct replacement applications.

Frequently Asked Questions (FAQ)

Q: Are the 555149-1 and 5555149-1 electrically identical?

A: Yes. Both connectors operate with identical electrical specifications: 50-position configuration, 2-row arrangement, gold contact finish at 30.0µin thickness, and outer shroud contact design. Electrical performance and signal integrity characteristics are equivalent.

Q: What is the significance of the Board Lock feature in the 5555149-1?

A: The Board Lock feature provides enhanced mechanical retention on the printed circuit board during assembly and operation. This feature does not affect electrical compatibility or mechanical fit with mating connectors. It represents an engineering improvement in the active equivalent design.

Q: Can the 5555149-1 be used as a direct replacement for the 555149-1 in existing designs?

A: Yes. The 5555149-1 is mechanically and electrically compatible with applications designed for the 555149-1. The identical mounting type (through-hole, right-angle), flange feature (4-40 housing/shell), and connector geometry ensure direct substitution without design modification.

Q: What is the difference in packaging between these two parts?

A: The original 555149-1 has unspecified packaging, while the 5555149-1 is supplied in tray packaging. Tray packaging facilitates automated component handling and inventory management. This difference does not affect connector performance or compatibility.

Q: Why is RoHS3 compliance important for the 5555149-1?

A: RoHS3 compliance indicates conformance to current regulatory requirements restricting hazardous substances in electrical and electronic equipment. For applications subject to RoHS regulations or customer compliance mandates, the 5555149-1 is the required selection. The original 555149-1, being RoHS non-compliant, cannot be used in regulated environments.

Q: Is the 5555149-1 suitable for new product designs?

A: Yes. The 5555149-1 is classified as an active product with substantial inventory availability (126400 pcs), ensuring long-term supply chain support. It is the appropriate selection for new designs requiring a 50-position D-Sub receptacle connector with the specified electrical and mechanical parameters.

Q: Do both connectors have the same moisture sensitivity classification?

A: Yes. Both the 555149-1 and 5555149-1 carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no moisture-related storage or handling restrictions.
