Substitute Part Grouping Explanation
Substitute parts for the DF1E-12S-2.5C are identified based on the following critical parameters that determine functional and mechanical compatibility:
- Connector Type & Contact Configuration: Receptacle with female socket contacts
- Position Count & Pitch: 12 positions at 0.098" (2.50mm) pitch
- Mounting & Termination: Free hanging in-line mounting with crimp termination
- Fastening Mechanism: Latch lock fastening type
- Row Configuration: Single row layout
The substitute part Molex 0351551200 meets all these core electrical and mechanical requirements, enabling direct functional replacement in applications requiring 12-position 2.50mm pitch receptacle housings.

Engineering Selection Recommendations
Both the DF1E-12S-2.5C and 0351551200 are active production parts with full regulatory compliance. The Hirose DF1E-12S-2.5C operates within -35°C to 85°C, while the Molex 0351551200 provides an extended operating range of -40°C to 105°C. Both parts carry MSL 1 rating and meet RoHS requirements. Selection between these parts should be based on application temperature requirements, material compatibility with the insulation material specified (Polyamide versus PBT), and supply chain availability.
Frequently Asked Questions (FAQ)
Q: Can the Molex 0351551200 directly replace the Hirose DF1E-12S-2.5C?
A: Yes. Both parts share identical electrical and mechanical specifications: 12-position receptacle housings with 2.50mm pitch, crimp termination, latch lock fastening, and single-row configuration. Compatibility is determined by these core parameters.
Q: What is the difference in insulation material between these parts?
A: The DF1E-12S-2.5C uses Polyamide (PA) Nylon, while the 0351551200 uses Polybutylene Terephthalate (PBT). Both materials are suitable for standard applications; material selection may depend on specific environmental or chemical exposure requirements.
Q: Do these housings include contacts?
A: No. Both the DF1E-12S-2.5C and 0351551200 are housings only. Contacts must be procured separately and are not included with these parts.
Q: What is the operating temperature difference?
A: The DF1E-12S-2.5C operates from -35°C to 85°C, while the 0351551200 operates from -40°C to 105°C. Applications requiring extended temperature ranges should specify the Molex part.
Q: Are both parts RoHS compliant?
A: Yes. The DF1E-12S-2.5C is RoHS Compliant, and the 0351551200 is ROHS3 Compliant. Both meet current regulatory requirements.
