Molex 0873690200 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0873690200 is a 2-position receptacle housing for rectangular connectors with 2.00mm pitch, designed for free-hanging in-line mounting applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing procurement and system maintenance. The housing accommodates female socket contacts via crimp termination and is RoHS3 compliant with unlimited moisture sensitivity rating.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0873690200 are qualified based on the following critical parameters:

Connector Type & Contact Configuration: Receptacle housing with female socket contacts
Position Count & Pitch: 2 positions at 0.079" (2.00mm) pitch
Mounting & Termination: Free-hanging in-line mounting with crimp contact termination
Electrical & Environmental Compliance: RoHS compliance and MSL rating of 1

Three substitute parts meet these core electrical and mechanical requirements:

Molex 0510050200 (MFR Recommended) - Direct functional equivalent with expanded inventory availability
TE Connectivity 440129-2 (MFR Recommended) - Active product status alternative from established connector manufacturer
Hirose DF3-2S-2C(18) (Parametric Equivalent) - Functionally equivalent with color variation

Engineering Selection Recommendations

Molex 0510050200 is the primary recommended substitute. As a Molex product with ROHS3 compliance and Last Time Buy status, it maintains manufacturer continuity while offering significantly higher inventory availability (215,801 units) compared to the obsolete 0873690200. Operating temperature range of -40°C to 105°C supports extended environmental applications.

TE Connectivity 440129-2 is the secondary recommended substitute for applications requiring active product status. This part is currently in active production from TE Connectivity's High Performance Interconnect (HPI) series, ensuring long-term supply chain stability. Operating temperature range of -25°C to 105°C is suitable for standard industrial applications. RoHS compliance is confirmed with 1,500 units in stock.

Hirose DF3-2S-2C(18) qualifies as a parametric equivalent meeting all core electrical and mechanical specifications. The red housing color differs from the natural color of the original part. Product status is obsolete. This option is suitable only when color differentiation is functionally acceptable in the application.

Frequently Asked Questions (FAQ)

Q: Can Molex 0510050200 directly replace Molex 0873690200 in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications: 2-position receptacle housing, 2.00mm pitch, female socket contacts, crimp termination, and free-hanging in-line mounting. Contact compatibility is maintained across both housings.

Q: What is the significance of the color difference in the Hirose DF3-2S-2C(18)?

A: The Hirose part features red housing versus natural housing in the original Molex part. From an electrical and mechanical standpoint, this is a cosmetic difference. Selection depends on whether color coding is functionally required in the application for identification or circuit tracing purposes.

Q: Why is TE Connectivity 440129-2 recommended despite different operating temperature range?

A: TE Connectivity 440129-2 maintains active product status, ensuring ongoing availability and supply chain continuity. The operating temperature range of -25°C to 105°C covers standard industrial applications. Selection should be based on specific application temperature requirements; if operation below -25°C is required, Molex 0510050200 with -40°C minimum is preferred.

Q: Are contacts included with these substitute housings?

A: No. All listed parts (original and substitutes) are housings only. Contacts must be procured separately and are not included with the housing.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts maintain RoHS compliance and MSL rating of 1 (unlimited moisture sensitivity). Molex 0510050200 is ROHS3 compliant. TE Connectivity 440129-2 and Hirose DF3-2S-2C(18) are RoHS compliant. REACH status varies by manufacturer; verify specific requirements for your application.
