XG5N-502 Equivalent & Substitute Parts

Part Overview

The XG5N-502 is a 50-position rectangular connector housing manufactured by Omron Electronics Inc-EMC Div. This receptacle connector features a 0.100" (2.54mm) pitch configuration with dual rows and crimp-style female socket contacts. The component is actively produced and RoHS compliant, serving applications requiring standard rectangular connector interfaces with reliable contact termination.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in compatible applications.

Substitute Part Grouping Explanation

Substitute parts for the XG5N-502 are qualified based on the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

Connector Type: Receptacle
Contact Type: Female Socket
Number of Positions: 50
Pitch: 0.100" (2.54mm)
Number of Rows: 2
Row Spacing: 0.100" (2.54mm)
Mounting Type: Free Hanging (In-Line)
Contact Termination: Crimp
Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

Insulation Material: Different materials acceptable if electrical and mechanical performance maintained
Color: Variations permitted (Black, Blue)
Operating Temperature Range: Substitute may extend beyond -55°C ~ 105°C
Manufacturer: Different manufacturers acceptable
Series designation: Different series acceptable

The three identified substitutes (0901430050, 65043-012LF, 65239-025LF) meet all mandatory parameters and are therefore electrically and mechanically interchangeable with the XG5N-502.

Engineering Selection Recommendations

All three substitute parts maintain active product status and comply with RoHS requirements, ensuring regulatory compliance and ongoing availability.

0901430050 (Molex C-Grid III 90143): Matches the XG5N-502 operating temperature range exactly (-55°C ~ 105°C) and achieves ROHS3 compliance. Insulation material differs (PPO vs. PBT) but maintains equivalent electrical and mechanical performance within specified parameters.

65043-012LF (Amphenol ICC Mini-PV™, Basics+): Operates within a narrower lower temperature range (-40°C ~ 105°C), which is acceptable for applications not requiring -55°C operation. RoHS compliant with modified polyphenylene insulation material.

65239-025LF (Amphenol ICC DUBOX™, MezzSelect™, Basics+): Extends operating temperature range to -65°C ~ 125°C, providing broader thermal capability than the main part. Housing color is blue rather than black. RoHS compliant with glass-filled thermoplastic insulation.

Selection among substitutes depends on specific application requirements regarding operating temperature range and housing color. All three parts are electrically and mechanically equivalent for standard 50-position, 2.54mm pitch rectangular connector applications.

Frequently Asked Questions (FAQ)

Q: Can the 65043-012LF substitute for XG5N-502 in applications requiring -55°C operation?

A: No. The 65043-012LF operating temperature range is -40°C ~ 105°C. Applications requiring -55°C minimum operation must use XG5N-502, 0901430050, or 65239-025LF.

Q: Does the blue housing color of 65239-025LF affect electrical compatibility?

A: No. Housing color is a cosmetic parameter. The blue 65239-025LF is electrically and mechanically equivalent to the black XG5N-502 for all connector functions.

Q: Are all substitutes RoHS compliant?

A: Yes. XG5N-502 is RoHS Compliant, 0901430050 is ROHS3 Compliant, and both 65043-012LF and 65239-025LF are RoHS Compliant. All meet regulatory requirements.

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

A: Insulation material differences (PBT, PPO, modified polyphenylene, thermoplastic) reflect different manufacturing approaches by each supplier. All materials specified meet the electrical and mechanical requirements for this connector category at the stated operating temperatures and voltage ratings.

Q: Can substitutes be mixed in the same assembly?

A: Yes. All four parts (XG5N-502, 0901430050, 65043-012LF, 65239-025LF) share identical electrical and mechanical interfaces. Mixed usage is permissible provided application temperature requirements are met by all parts used.

Q: Which substitute offers the widest operating temperature range?

A: The 65239-025LF operates from -65°C ~ 125°C, extending beyond the XG5N-502 range of -55°C ~ 105°C.
