YLR-02VF Equivalent & Substitute Parts

Part Overview

The YLR-02VF is a 2-position rectangular connector housing manufactured by JST Sales America Inc. in the YL series. This receptacle housing accepts male pins with a 0.177" (4.50mm) pitch and is designed for free-hanging, in-line applications with crimp termination and latch holder fastening. The part is active in production status with 1259 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to component availability, supply chain considerations, or design flexibility within the allowed parameter specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the YLR-02VF are identified based on strict equivalence of the following critical parameters:

• Connector type (Receptacle)
• Contact type (Male Pin)
• Number of positions (2)
• Pitch specification (0.177" / 4.50mm)
• Number of rows (1)
• Mounting configuration (Free Hanging, In-Line)
• Contact termination method (Crimp)
• Fastening mechanism (Latch Holder)

The substitute part 1717672-1 meets all these core electrical and mechanical requirements. Variations in color, insulation material composition, operating temperature range, and compliance certifications do not affect the fundamental substitution eligibility, as these parameters fall within acceptable engineering tolerances for this connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the YLR-02VF and 1717672-1 are active production components with full regulatory compliance. The YLR-02VF maintains ROHS3 compliance, while the 1717672-1 maintains RoHS compliance. Both parts carry MSL 1 (Unlimited) moisture sensitivity ratings and REACH Unaffected status. The 1717672-1 offers an extended operating temperature range (-40°C ~ 125°C) compared to the YLR-02VF (-25°C ~ 90°C), providing additional thermal margin in applications requiring lower or higher temperature operation. Selection between these parts should be based on application-specific requirements for color, material composition, and thermal performance, as all core electrical and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 1717672-1 be used as a direct replacement for the YLR-02VF?

A: Yes. Both parts share identical specifications for connector type, contact type, number of positions, pitch, mounting configuration, termination method, and fastening mechanism. These parameters define functional compatibility in rectangular connector applications.

Q: What are the differences between these parts?

A: The primary differences are color (White vs. Black), insulation material composition (Polyamide vs. Thermoplastic Glass Filled), and operating temperature range (-25°C ~ 90°C vs. -40°C ~ 125°C). These variations do not affect electrical or mechanical compatibility.

Q: Does the extended temperature range of the 1717672-1 affect compatibility?

A: No. An extended operating temperature range represents a superset of the original specification and does not create incompatibility. Applications operating within the YLR-02VF temperature range will function identically with the 1717672-1.

Q: Are the contacts interchangeable between these housings?

A: Contact compatibility is determined by pitch, contact type, and termination method. Both housings accept male pin contacts with 0.177" (4.50mm) pitch and crimp termination. Contacts specified for either housing series must be verified against the specific contact part number.

Q: What is the significance of the different insulation materials?

A: Both materials (Polyamide PA66 and Thermoplastic Glass Filled) are standard for rectangular connector housings in this category. Material selection affects mechanical properties and environmental resistance but does not alter electrical performance or pitch compatibility.

Q: Do both parts require the same mating connector?

A: Yes. Both receptacle housings accept identical plug connectors with matching 0.177" (4.50mm) pitch and 2-position configuration. Mating connector selection is independent of housing manufacturer.
