Engineering Selection Recommendations

TE Connectivity AMP Connectors 281838-4 is the primary substitute when black color is required. This part offers enhanced thermal performance (-55°C ~ 125°C) compared to the 928040-4 and maintains TE Connectivity manufacturing consistency. Glass-filled PBT insulation provides improved mechanical strength. RoHS Compliance is maintained. Inventory availability is significantly higher at 13,768 pieces.

TE Connectivity AMP Connectors 925366-4 and 925369-4 serve as substitutes for green color applications within the AMPMODU Mod IV series. Both parts support extended low-temperature operation (-65°C) and maintain RoHS Compliance. The distinction between PA and PA66 nylon materials reflects different mechanical and thermal characteristics within the same series. Selection between these two depends on specific material property requirements.

Molex 0050579204 provides the highest inventory availability (55,265 pieces) and operates across -40°C ~ 105°C. This part is ROHS3 Compliant and represents a cross-manufacturer alternative with polyester glass-filled insulation. Selection is appropriate when supply chain continuity and volume availability are prioritized.

Amphenol ICC (FCI) 65039-033LF offers black color with modified polyphenylene insulation and operates across -40°C ~ 105°C. This part is RoHS Compliant and represents a third-party manufacturer option with established Mini-PV™ and Basics+ series compatibility.

Amphenol ICC (FCI) 65240-004LF provides blue color with the widest operating temperature range (-65°C ~ 125°C) and is suitable for demanding thermal environments. Thermoplastic glass-filled insulation and RoHS Compliance are maintained. This part is appropriate when both color specification and extended temperature performance are required.

All substitute parts maintain identical core connector specifications (4-position, 0.100" pitch, female socket, crimp termination, free-hanging in-line mounting) and are suitable for direct substitution based on color, material, and thermal performance requirements.

Frequently Asked Questions (FAQ)

Q: Can 928040-4 be directly replaced with 281838-4?

A: Yes. Both parts share identical core specifications: 4-position receptacle, 0.100" (2.54mm) pitch, female socket contacts, crimp termination, and free-hanging in-line mounting. The primary differences are color (Natural vs. Black), insulation material composition (PBT vs. PBT Glass Filled), and operating temperature range (-55°C ~ 125°C for 281838-4). Direct substitution is valid when black color and enhanced thermal performance are acceptable.

Q: What is the difference between 925366-4 and 925369-4?

A: Both parts are green-colored receptacles within the AMPMODU Mod IV series with identical electrical and mechanical specifications. The distinction lies in insulation material: 925366-4 uses Polyamide (PA) Nylon, while 925369-4 uses Polyamide (PA66) Nylon 6/6. Both operate across -65°C ~ 105°C. Selection depends on specific material property requirements for the application.

Q: Is the Molex 0050579204 compatible with TE Connectivity 928040-4?

A: Yes. The Molex 0050579204 maintains all core connector specifications required for substitution: 4-position receptacle, 0.100" (2.54mm) pitch, female socket contacts, crimp termination, and free-hanging in-line mounting. The part operates across -40°C ~ 105°C with polyester glass-filled insulation and is ROHS3 Compliant. Cross-manufacturer substitution is valid when supply and material specifications align with application requirements.

Q: Which substitute part offers the widest operating temperature range?

A: Both TE Connectivity 281838-4 and Amphenol ICC 65240-004LF operate across -55°C ~ 125°C and -65°C ~ 125°C respectively, representing the extended thermal performance options.

Q: Are all substitute parts RoHS Compliant?

A: Yes. All listed substitute parts maintain RoHS Compliance status. TE Connectivity parts are RoHS Compliant, Molex 0050579204 is ROHS3 Compliant, and Amphenol ICC parts are RoHS Compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What inventory considerations apply to substitution?

A: Molex 0050579204 offers the highest inventory availability at 55,265 pieces, followed by TE Connectivity 281838-4 at 13,768 pieces. The original 928040-4 has 1,033 pieces in stock. When supply chain continuity is critical, the Molex option provides significant inventory buffer. All parts are listed as Active product status with new original stock.

Q: Can color be changed during substitution?

A: Yes. Color variation is an allowed substitution parameter. Available colors include Natural (928040-4), Black (281838-4, 0050579204, 65039-033LF), Green (925366-4, 925369-4), and Blue (65240-004LF).
