Molex 0879118011 Equivalent & Substitute Parts

Part Overview

The Molex 0879118011 is an 80-position rectangular connector header with right-angle through-hole mounting and 2.54mm pitch. This breakaway header is designed for board-to-board or cable connections in applications including automotive, general purpose, lighting, medical, and telecommunications. The part is currently active in production with 911 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in designs requiring this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0879118011 are identified based on strict alignment of the following critical parameters:

• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Number of Positions: 80
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Unshrouded
• Style: Board to Board or Cable
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The Sullins Connector Solutions PREC040DBAN-M71RC meets all critical substitution criteria. Minor variations in contact length, insulation height, contact material, and insulation material do not affect functional interchangeability in applications where the primary requirements are pitch, position count, mounting configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0879118011 and Sullins PREC040DBAN-M71RC are active production parts with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts should be based on:

Molex 0879118011: Select when gold-plated mating contacts are required for enhanced corrosion resistance or when LCP insulation material is specified in design requirements.

Sullins PREC040DBAN-M71RC: Select when PBT insulation material is acceptable and tin-plated mating contacts meet application requirements. This part offers higher inventory availability (2623 units in stock versus 911 units) and includes specified operating temperature range (-40°C ~ 105°C) and current rating (3A).

Both parts are functionally equivalent for standard board-to-board and cable connection applications in automotive, general purpose, lighting, medical, and telecommunications environments.

Frequently Asked Questions (FAQ)

Q: Can the Sullins PREC040DBAN-M71RC be used as a direct replacement for the Molex 0879118011?

A: Yes. Both parts share identical pitch (2.54mm), position count (80), row configuration (2 rows), mounting type (through-hole right-angle), and compliance certifications (ROHS3, UL94 V-0). The parts are functionally interchangeable in applications where the connector interface and electrical requirements are met.

Q: What are the differences in contact materials and finishes?

A: The Molex part uses copper alloy contacts with gold mating finish and tin post finish. The Sullins part uses brass contacts with tin finish on both mating and post surfaces. Gold plating provides superior corrosion resistance; tin plating is suitable for standard industrial applications. Selection depends on environmental exposure and corrosion requirements.

Q: Are there differences in insulation materials?

A: Yes. The Molex part uses glass-filled Liquid Crystal Polymer (LCP); the Sullins part uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and lower moisture absorption; PBT is a standard engineering thermoplastic. Material selection should align with specific design thermal and environmental requirements.

Q: What is the significance of the contact length variations?

A: Contact length differences (Molex: 0.240" mating / 0.125" post; Sullins: 0.230" mating / 0.120" post) are within typical manufacturing tolerances for this connector class. These minor variations do not affect mating depth or electrical performance in standard applications.

Q: Does the Sullins part include operating temperature and current specifications?

A: Yes. The Sullins PREC040DBAN-M71RC specifies -40°C ~ 105°C operating temperature range and 3A current rating. The Molex part does not include these specifications in the provided data. If your application requires documented thermal or current performance, the Sullins part provides explicit ratings.

Q: Are both parts available in the same packaging?

A: The Molex part packaging is not specified. The Sullins part is supplied in bulk packaging. Confirm packaging requirements with your procurement process.
