Molex 0988171040 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0988171040 is a 4-position receptacle housing for rectangular connectors, manufactured in white polybutylene terephthalate (PBT) material. This component is part of the NSCC 98817 series and is designed for free-hanging, in-line mounting applications with crimp contact termination and latch holder fastening. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified when identical electrical and mechanical specifications are maintained across the connector housing family, with variation limited to housing color.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0988171040 are identified within the NSCC 98817 series based on electrical and mechanical parameter equivalence. The following parameters remain constant across all substitute parts and define the substitution group:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 4
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Insulation Material: Polybutylene Terephthalate (PBT), Polyester
• Operating Temperature Range: -40°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The only variable parameter within this substitution group is housing color. Substitute parts 0988171045 (Green) and 0988171048 (Gray) maintain identical functional and electrical characteristics to the primary part 0988171040 (White).

Parameter Comparison

Engineering Selection Recommendations

All three parts—0988171040, 0988171045, and 0988171048—maintain Active product status and ROHS3 compliance. Selection between these parts is determined by application-specific housing color requirements. From a compliance and regulatory perspective, all parts are equivalent. The choice of substitute part depends solely on whether the application design specifies a particular housing color for identification, traceability, or visual distinction purposes. No electrical or mechanical performance differences exist between these parts.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0988171040 (White) with the 0988171045 (Green) or 0988171048 (Gray)?

A: Yes. All three parts are functionally equivalent rectangular connector housings within the NSCC 98817 series. They share identical electrical specifications, mechanical dimensions, mounting characteristics, and operating parameters. The only difference is housing color.

Q: Are there any compatibility issues when using substitute parts?

A: No compatibility issues exist. The substitute parts maintain identical contact type (Female Socket), number of positions (4), mounting type (Free Hanging In-Line), contact termination (Crimp), and fastening type (Latch Holder). They are mechanically and electrically interchangeable.

Q: Do all parts have the same operating temperature range?

A: Yes. All parts in this substitution group operate across the same temperature range of -40°C to 85°C.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited).

Q: What is the primary reason to select one color variant over another?

A: Housing color selection is driven by application requirements for visual identification, circuit board layout conventions, or design documentation specifications. From a technical standpoint, all color variants are equivalent.

Q: Are contacts included with these connector housings?

A: No. All parts in this group are housings only. Contacts are not included and must be sourced separately.
