Molex 0521170413 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0521170413 is a 2-position receptacle housing for rectangular connectors with a 2.50mm pitch, designed for waterproof applications in the Mizu-P25 series. This component is an active product with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit equivalent housing configurations.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0521170413 are qualified based on the following critical parameters:

2-position receptacle housing configuration
2.50mm pitch spacing
Female socket contact type
Crimp termination method
Black color
Free hanging in-line mounting
Waterproof design capability
RoHS3 compliance
MSL 1 rating

Two substitute parts meet these criteria: the JAE Electronics MX19002S51 (manufacturer-recommended equivalent) and the Molex 0522130211 (parametric equivalent within the same series).

Engineering Selection Recommendations

The Molex 0522130211 is the primary parametric equivalent, sharing identical fastening type (Locking Ramp), insulation material composition, operating temperature range, and waterproof IP67 rating with the original part. Both are Molex Mizu-P25 series components with matching RoHS3 and MSL certifications.

The JAE Electronics MX19002S51 is the manufacturer-recommended alternative, offering full compliance with core substitution parameters including pitch, position count, contact type, and termination method. The primary design difference is the Latch Lock fastening mechanism versus the Locking Ramp used in the Molex housings. Operating temperature specification is not provided for the JAE part; applications requiring the -40°C ~ 105°C range should verify compatibility with JAE Electronics technical documentation.

All three parts maintain active product status and RoHS3 compliance, supporting long-term availability and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the JAE Electronics MX19002S51 be used as a direct replacement for the Molex 0521170413?

A: The MX19002S51 meets all critical substitution parameters: 2-position receptacle, 2.50mm pitch, female socket contacts, crimp termination, and waterproof design. The fastening mechanism differs (Latch Lock versus Locking Ramp), which may affect mating force and connector retention characteristics. Mechanical compatibility with mating plugs should be verified for your specific application.

Q: What is the difference between the Molex 0521170413 and 0522130211?

A: Both parts are Molex Mizu-P25 series receptacle housings with identical electrical and mechanical specifications, including pitch, position count, operating temperature, and waterproof rating. The primary distinction is the series designation (52117 versus 52213), reflecting different product generations within the same connector family. The 0522130211 is a parametric equivalent suitable for applications where the original part is unavailable.

Q: Are there packaging differences between these substitute parts?

A: The Molex 0521170413 and 0522130211 are supplied in Tray packaging, while the JAE Electronics MX19002S51 is supplied in Bulk packaging. Packaging format may affect inventory management and handling procedures but does not impact electrical or mechanical performance.

Q: Do all substitute parts support the same operating temperature range?

A: The Molex 0521170413 and 0522130211 both specify -40°C ~ 105°C operating temperature. The JAE Electronics MX19002S51 does not provide an operating temperature specification in the available data. Applications requiring operation across the full -40°C ~ 105°C range should confirm JAE part compatibility through technical documentation.

Q: Are all parts RoHS3 compliant?

A: Yes, all three parts—Molex 0521170413, JAE Electronics MX19002S51, and Molex 0522130211—are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
