Amphenol ICC 65039-233LF Rectangular Connector Receptacle Housing - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 65039-233LF is a 4-position rectangular connector receptacle housing with 0.100" (2.54mm) pitch, designed for free-hanging in-line applications. This component belongs to the Mini-PV™ and Basics+ series and is classified as Active product status. The housing accommodates crimp-terminated female socket contacts and operates across -40°C to 105°C. Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: 4-position configuration, 0.100" pitch, receptacle connector type with female socket contacts, single-row layout, and crimp termination. Substitutes may vary in insulation material composition, color, operating temperature range, and manufacturer series while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following core parameters:

• Connector Type: Receptacle (all substitutes match)
• Contact Type: Female Socket (all substitutes match)
• Number of Positions: 4 (all substitutes match)
• Pitch: 0.100" (2.54mm) (all substitutes match)
• Number of Rows: 1 (all substitutes match)
• Mounting Type: Free Hanging (In-Line) (all substitutes match)
• Contact Termination: Crimp (all substitutes match)

All identified substitute parts meet these mandatory electrical and mechanical criteria. Variations exist in insulation material, color, operating temperature range, and manufacturer series. These variations do not affect the core substitution relationship when the above parameters are satisfied.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and RoHS compliance. Selection among substitutes should be based on:

Amphenol ICC substitutes (65039-033LF, 65240-004LF): Maintain identical series lineage with the main part. Part 65039-033LF is a direct equivalent within the same Mini-PV™ and Basics+ series with identical material and temperature specifications. Part 65240-004LF extends the operating temperature range to -65°C ~ 125°C and uses thermoplastic glass-filled insulation, suitable for applications requiring broader thermal performance.

Molex substitute (0050579204): Provides equivalent electrical and mechanical function with ROHS3 compliance. Operates within the same temperature range as the main part (-40°C ~ 105°C) with polyester glass-filled insulation.

TE Connectivity substitutes (281838-4, 925366-4, 925369-4): All maintain RoHS compliance. Part 281838-4 extends operating temperature to -55°C ~ 125°C with PBT glass-filled insulation. Parts 925366-4 and 925369-4 are from the AMPMODU Mod IV series with polyamide-based insulation and -65°C ~ 105°C operating range, differing only in PA versus PA66 material composition.

Frequently Asked Questions (FAQ)

Q: Can 65039-033LF directly replace 65039-233LF? A: Yes. Both parts share identical electrical specifications (4-position, 0.100" pitch, female socket, crimp termination), series designation (Mini-PV™, Basics+), insulation material (Polyphenylene, Modified), and operating temperature range (-40°C ~ 105°C). They are parametrically equivalent.

Q: What is the primary difference between 65240-004LF and the main part? A: The 65240-004LF differs in color (blue versus black), insulation material (thermoplastic glass-filled versus polyphenylene modified), and operating temperature range (-65°C ~ 125°C versus -40°C ~ 105°C). Core electrical and mechanical parameters remain identical.

Q: Are cross-manufacturer substitutes (Molex, TE Connectivity) electrically compatible? A: Yes. All substitute parts maintain the same connector type (receptacle), contact type (female socket), position count (4), pitch (0.100"), mounting type (free hanging in-line), and termination method (crimp). These parameters define functional compatibility.

Q: How do insulation material differences affect substitution? A: Insulation material variations (polyphenylene, thermoplastic, polyester, PBT, polyamide) do not affect the core substitution relationship when all electrical and mechanical parameters match. Material selection depends on application-specific requirements such as chemical resistance, mechanical strength, or thermal cycling performance.

Q: What is the significance of operating temperature range variations? A: Substitutes with extended temperature ranges (e.g., 281838-4 at -55°C ~ 125°C) are suitable for applications requiring broader thermal performance. The main part's -40°C ~ 105°C range is a subset of these extended ranges, making such substitutes compatible for standard applications.

Q: Do all substitutes have the same moisture sensitivity level? A: Yes. All parts listed, including the main part and all substitutes, carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there inventory considerations when selecting substitutes? A: Inventory levels vary significantly. The Molex 0050579204 offers the highest availability (55265 pcs), while TE Connectivity 925369-4 has the lowest (1573 pcs). Amphenol ICC 65039-033LF provides 2706 pcs. Inventory should be evaluated based on project lead time and volume requirements.
