Key Parameters

Substitute Part Grouping Explanation

The MDF7-20P-2.54DS(56) has one direct substitute within the MDF7 series: MDF7-20P-2.54DS(96). Substitution eligibility is determined by the following critical parameters that must remain identical:

• Number of Positions: 20
• Pitch - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Current Rating: 3A
• Voltage Rating: 250V (or 250VAC equivalent)
• Operating Temperature Range: -35°C ~ 85°C
• Contact Material: Brass
• Contact Finish - Mating: Gold
• Insulation Material: Polybutylene Terephthalate (PBT)
• RoHS Compliance: Yes

The substitute part differs in product status (Active vs. Obsolete) and application style (Board to Cable/Wire vs. Board to Board), with minor variations in contact length specifications within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-20P-2.54DS(96) is the direct equivalent substitute for the obsolete MDF7-20P-2.54DS(56). Both parts maintain identical electrical specifications (3A current rating, 250V voltage rating), mechanical dimensions (20 positions, 2.54mm pitch, through-hole right-angle mounting), and material certifications (UL94 V-0, RoHS Compliant).

The primary distinction is product status: MDF7-20P-2.54DS(96) is Active, ensuring long-term availability and supply chain continuity. The contact length variation (0.292" vs. 0.293" mating contact) represents a 0.03mm difference within standard manufacturing tolerances and does not affect functional compatibility.

Both parts carry identical moisture sensitivity (MSL 1), operating temperature range (-35°C to 85°C), and compliance certifications, supporting direct substitution in existing designs without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can MDF7-20P-2.54DS(96) be used as a direct replacement for MDF7-20P-2.54DS(56)?

A: Yes. Both parts share identical electrical ratings (3A, 250V), mechanical configuration (20 positions, 2.54mm pitch, through-hole right-angle), contact materials (brass with gold finish), and insulation specifications (PBT, UL94 V-0). The contact length difference of 0.03mm is within standard manufacturing tolerance and does not affect mating compatibility.

Q: What is the significance of the product status difference?

A: MDF7-20P-2.54DS(56) is classified as Obsolete, indicating discontinued production and limited future availability. MDF7-20P-2.54DS(96) is Active, ensuring ongoing manufacturing and reliable procurement for current and future applications.

Q: Are there packaging differences between these parts?

A: MDF7-20P-2.54DS(56) packaging is unspecified in available data. MDF7-20P-2.54DS(96) is supplied in Bag packaging. Packaging differences do not affect electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS Compliant, carry UL94 V-0 flammability rating, and have MSL 1 (Unlimited) moisture sensitivity classification. Compliance certifications are identical.

Q: What is the difference between "Board to Board" and "Board to Cable/Wire" style designations?

A: Style designation indicates the intended mating interface. MDF7-20P-2.54DS(56) is specified for Board to Board connections, while MDF7-20P-2.54DS(96) is specified for Board to Cable/Wire connections. Both parts use identical header pin configurations and are mechanically compatible with standard 2.54mm pitch receptacles.
