Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF57-5S-1.2C is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle housing
• Contact Type: Female Socket configuration
• Number of Positions: 5-position layout
• Pitch: 0.047" (1.20mm) contact spacing
• Number of Rows: Single row configuration
• Mounting Type: Free Hanging (In-Line) orientation
• Contact Termination: Crimp connection method
• Fastening Type: Swing Lock mechanism
• Color: White housing

The DF57H-5S-1.2C qualifies as a direct substitute based on full alignment with all specified parameters. The primary distinction is the product status transition from Obsolete to Active, indicating continued manufacturer support and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The DF57H-5S-1.2C is the recommended substitute for the obsolete DF57-5S-1.2C. This recommendation is based on:

• Full electrical and mechanical parameter equivalence across all critical specifications
• Active product status ensuring ongoing manufacturer support and supply chain availability
• RoHS3 Compliance certification for environmental regulatory adherence
• REACH Unaffected status confirming compliance with chemical substance regulations
• Identical MSL rating and export classification (ECCN EAR99)
• Improved inventory availability (3400 pcs vs. 926 pcs)

The DF57H series represents the current generation of this connector housing line, with the DF57H-5S-1.2C providing direct functional and physical compatibility for applications previously designed around the DF57-5S-1.2C.

Frequently Asked Questions (FAQ)

Q: Are the DF57-5S-1.2C and DF57H-5S-1.2C physically interchangeable?

A: Yes. Both parts share identical mechanical dimensions, pitch spacing (1.20mm), mounting configuration (Free Hanging In-Line), and fastening mechanism (Swing Lock). Physical interchangeability is confirmed across all specified parameters.

Q: What is the primary reason for substitution?

A: The DF57-5S-1.2C is classified as Obsolete, while the DF57H-5S-1.2C is Active. Substitution ensures access to a supported product line with guaranteed long-term availability and manufacturer technical support.

Q: Are there any electrical performance differences between these parts?

A: No electrical performance differences exist. Both parts are 5-position receptacle housings with identical contact type (Female Socket), termination method (Crimp), and fastening type (Swing Lock). Electrical specifications are equivalent.

Q: Does the DF57H-5S-1.2C require different contact pins?

A: No. Both housings accept the same crimp contact specifications. The note "Contacts Not Included" applies to both parts, indicating contacts are procured separately and are interchangeable between the two housing variants.

Q: What compliance certifications apply to the substitute part?

A: The DF57H-5S-1.2C carries RoHS3 Compliance and REACH Unaffected status. Both parts share identical MSL rating (1 - Unlimited) and export classification (ECCN EAR99).

Q: Is there a packaging difference between the two parts?

A: The DF57-5S-1.2C packaging is listed as unspecified, while the DF57H-5S-1.2C is supplied in Bulk packaging. This represents an improvement in standard supply format for the active product line.
