186-015-292L551 D-Sub Receptacle Connector Equivalent & Substitute Parts

Part Overview

The 186-015-292L551 is a 15-position D-Sub receptacle connector manufactured by NorComp Inc., designed for panel mount applications with IDC ribbon cable termination. This connector features female sockets, steel tin-plated shell, and gold-flashed contacts rated for 1A continuous current. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 186-015-292L551 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector style (D-Sub)
• Connector type (Receptacle, Female Sockets)
• Number of positions (15)
• Number of rows (2)
• Shell size and connector layout (2 DA, A)
• Mounting type (Panel Mount)
• Termination method (IDC, Ribbon Cable)

Allowable Variations:

• Current rating may be equal to or greater than the original specification
• Operating temperature range may be equal to or exceed the original specification
• Contact finish thickness (Flash) remains consistent
• Flange feature configuration may differ (Housing/Shell vs. Cable Side)
• Dielectric material composition may vary while maintaining UL94 V-0 rating
• Wire gauge specifications within acceptable ribbon cable standards
• Contact material composition (Phosphor Bronze vs. Copper Alloy)
• Product status transition from Obsolete to Active is acceptable for substitution purposes

The substitute part 184A015-292L011 meets all mandatory matching parameters and demonstrates acceptable variations in allowable categories.

Parameter Comparison

Engineering Selection Recommendations

The 184A015-292L011 is a direct substitute for the obsolete 186-015-292L551. Both connectors are manufactured by NorComp Inc. and maintain identical mechanical and electrical interface specifications for D-Sub 15-position panel mount IDC ribbon cable applications.

The substitute part offers enhanced specifications: increased current rating (1.5A vs. 1A) and extended operating temperature range (-55°C ~ 125°C vs. -55°C ~ 100°C). Both parts maintain UL94 V-0 flammability compliance and ROHS3 certification. The transition from Obsolete to Active product status ensures continued availability and supply chain reliability for new procurements and system replacements.

Frequently Asked Questions (FAQ)

Q: Can the 184A015-292L011 be used as a direct replacement for the 186-015-292L551?

A: Yes. Both connectors share identical D-Sub 15-position receptacle configuration, panel mount design, and IDC ribbon cable termination. The substitute part meets all functional and mechanical interface requirements.

Q: What are the differences between these two connectors?

A: The primary differences are product status (Obsolete vs. Active), current rating (1A vs. 1.5A), operating temperature range (-55°C to 100°C vs. -55°C to 125°C), flange feature configuration (Housing/Shell vs. Cable Side), dielectric material composition, and contact material type. These variations do not affect substitution compatibility.

Q: Does the higher current rating of the substitute part affect compatibility?

A: No. A higher current rating is an acceptable variation that does not compromise compatibility. Systems designed for 1A operation will function correctly with a 1.5A-rated connector.

Q: Are there packaging differences between these parts?

A: The main part has unspecified packaging, while the substitute is supplied in Tray packaging. This affects procurement and handling but does not impact electrical or mechanical performance.

Q: What is the significance of the Obsolete status?

A: The 186-015-292L551 is no longer manufactured. The 184A015-292L011 is an active product with ongoing manufacturing and supply availability, making it the recommended choice for new applications and system replacements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 186-015-292L551 and 184A015-292L011 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
