VLR-04VN Equivalent & Substitute Parts

Part Overview

The VLR-04VN is a 4-position rectangular connector receptacle housing manufactured by JST Sales America Inc. This component is part of the VL series and is designed for free-hanging in-line applications with crimp contact termination. The housing is white polyamide (PA66/Nylon 6/6) material rated for -25°C to 90°C operation. This part is currently active in production with 1098 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement in applications where the main part is unavailable or when design requirements necessitate alternative connector configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLR-04VN is determined by the following critical parameters:

• Number of Positions: Must be 4
• Pitch: Must be 0.244" (6.20mm)
• Contact Termination: Must be Crimp
• Mounting Type: Must be Free Hanging (In-Line)
• Insulation Material: Must be Polyamide (PA66), Nylon 6/6
• Regulatory Compliance: Must maintain RoHS and REACH compliance status

The substitute part 4-178842-1 meets these core electrical and mechanical requirements. However, the connector type differs (Plug vs. Receptacle) and the contact type is opposite (Female Socket vs. Male Pin), which reflects the complementary nature of mating connector pairs in the same system.

Parameter Comparison

Engineering Selection Recommendations

Both the VLR-04VN and 4-178842-1 are active production components with full regulatory compliance. The VLR-04VN maintains ROHS3 compliance, while the substitute maintains RoHS compliance. Both components carry MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special storage or handling requirements.

The substitute part 4-178842-1 offers an extended operating temperature range (-30°C to 105°C) compared to the main part (-25°C to 90°C), providing additional thermal margin in applications requiring broader temperature performance.

Selection between these parts should be based on connector type requirements within the system architecture: receptacle housings for one mating interface and plug housings for the complementary interface.

Frequently Asked Questions (FAQ)

Q: Can the VLR-04VN and 4-178842-1 be used interchangeably?

A: These parts are not direct one-to-one replacements. The VLR-04VN is a receptacle housing, while 4-178842-1 is a plug housing. They are complementary connector types designed to mate with each other. Selection depends on the specific interface role required in your application.

Q: What does the 0.244" (6.20mm) pitch specification mean?

A: Pitch refers to the center-to-center distance between adjacent contact positions. Both parts maintain identical 6.20mm pitch, ensuring compatibility within the same connector system.

Q: Are both parts RoHS compliant?

A: Yes. The VLR-04VN is ROHS3 compliant, and the 4-178842-1 is RoHS compliant. Both meet regulatory requirements for restricted substance elimination.

Q: Do these housings include contacts?

A: No. Both the VLR-04VN and 4-178842-1 are housings only. Contacts must be sourced separately and crimped into the housing according to manufacturer specifications.

Q: What is the difference in operating temperature ranges?

A: The VLR-04VN operates from -25°C to 90°C, while 4-178842-1 operates from -30°C to 105°C. The substitute part provides a wider thermal operating window suitable for applications requiring extended temperature performance.

Q: Are special storage conditions required for these parts?

A: No. Both components carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard component storage conditions are sufficient.
