Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF57-3S-1.2C(09) is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 3 positions at 0.047" (1.20mm) spacing
• Row Configuration: Single row layout
• Mounting & Termination: Free hanging in-line mounting with crimp termination
• Fastening Mechanism: Swing lock fastening
• Environmental Rating: MSL 1 (Unlimited moisture sensitivity level)

The substitute part DF57H-3S-1.2C(08) maintains full equivalence across all critical electrical and mechanical parameters. The primary distinction is product status: the substitute transitions from obsolete to active production status, ensuring long-term availability and supply chain continuity.

Engineering Selection Recommendations

The DF57H-3S-1.2C(08) is the direct substitute for the obsolete DF57-3S-1.2C(09). Selection of the substitute part is justified on the following grounds:

• Product Status: The substitute is in active production, ensuring reliable procurement and supply chain continuity compared to the obsolete original part.
• Regulatory Compliance: The substitute carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.
• Functional Equivalence: All critical electrical and mechanical parameters remain unchanged, ensuring direct compatibility in existing designs without circuit or mechanical modifications.
• Availability: Current inventory of 6,851 pieces supports immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the DF57H-3S-1.2C(08) be used as a direct replacement for the DF57-3S-1.2C(09)?

A: Yes. Both parts are 3-position receptacle housings with 0.047" (1.20mm) pitch, female socket contacts, swing lock fastening, and crimp termination. All critical electrical and mechanical parameters are equivalent, enabling direct substitution without design modifications.

Q: What is the primary reason for substitution?

A: The original part DF57-3S-1.2C(09) is obsolete. The substitute DF57H-3S-1.2C(08) is in active production, ensuring long-term availability and supply chain stability.

Q: Are there differences in insulation material or operating temperature?

A: The substitute specifies Liquid Crystal Polymer (LCP) insulation material and an operating temperature range of -35°C to 85°C. These specifications were not provided for the original part. If your application requires confirmation of these parameters for the original part, consult the original manufacturer datasheet.

Q: What packaging is available for the substitute part?

A: The substitute is available in bulk packaging, with 6,851 pieces currently in stock.

Q: Are there any compliance differences between the two parts?

A: The substitute carries ROHS3 compliance and REACH unaffected status. Compliance information was not specified for the original part. If regulatory compliance is a design requirement, the substitute meets current environmental standards.
