MDF7-19P-2.54DS(56) Equivalent & Substitute Parts

Part Overview

The MDF7-19P-2.54DS(56) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-board applications with 19 positions at 0.100" (2.54mm) pitch. This part is classified as obsolete, making identification of active equivalent models essential for ongoing design support and procurement continuity. The substitute part MDF7-19P-2.54DS(96) provides functional compatibility while maintaining current product status and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-19P-2.54DS(56) is determined by the following critical parameters:

• Manufacturer and series consistency (Hirose Electric, MDF7 series)
• Identical connector type and contact configuration (Header, Male Pin)
• Matching position count and pitch specification (19 positions, 0.100" / 2.54mm)
• Equivalent electrical ratings (3A current, 250V voltage)
• Identical mounting and termination method (Through Hole, Right Angle, Solder)
• Matching material and compliance specifications (PBT insulation, UL94 V-0, RoHS Compliant)
• Operating temperature range compatibility (-35°C ~ 85°C)

The MDF7-19P-2.54DS(96) meets all substitution criteria. The primary difference is application style (Board to Cable/Wire versus Board to Board) and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-19P-2.54DS(96) is the direct substitute for the obsolete MDF7-19P-2.54DS(56). Both parts maintain identical electrical and mechanical specifications across all critical parameters: 19-position configuration, 0.100" pitch, 3A current rating, 250V voltage rating, and operating temperature range of -35°C to 85°C.

The MDF7-19P-2.54DS(96) offers the advantage of active product status with current manufacturing support and documented availability (813 Pcs in stock versus 684 Pcs for the obsolete variant). Both parts carry RoHS compliance and UL94 V-0 flammability certification, ensuring regulatory alignment for new designs and legacy system maintenance.

Selection of the MDF7-19P-2.54DS(96) is supported by identical material composition, contact finish specifications, and moisture sensitivity classification, eliminating technical barriers to direct substitution in existing board designs.

Frequently Asked Questions (FAQ)

Q: Can the MDF7-19P-2.54DS(96) directly replace the MDF7-19P-2.54DS(56) in existing designs?

A: Yes. Both parts share identical electrical ratings (3A, 250V), mechanical dimensions (19 positions, 0.100" pitch), mounting configuration (through-hole, right-angle), and material specifications (PBT insulation, gold-plated brass contacts). The parts are functionally interchangeable at the board level.

Q: What is the difference between these two part numbers?

A: The primary difference is product status: MDF7-19P-2.54DS(56) is obsolete, while MDF7-19P-2.54DS(96) is active. The secondary difference is application designation: (56) is specified for board-to-board connections, while (96) is specified for board-to-cable/wire connections. Both support identical mating contact specifications and electrical performance.

Q: Are there packaging differences between these parts?

A: The MDF7-19P-2.54DS(56) packaging is not specified in available documentation. The MDF7-19P-2.54DS(96) is supplied in bag packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS Compliant, carry UL94 V-0 flammability certification, and share identical moisture sensitivity level classification (MSL 1 - Unlimited). Both are classified under ECCN EAR99 and HTSUS 8536.69.4040.

Q: What is the contact length difference between these parts?

A: Contact length - mating is 0.292" (7.42mm) for MDF7-19P-2.54DS(56) and 0.293" (7.45mm) for MDF7-19P-2.54DS(96). This 0.03mm difference is within standard manufacturing tolerance and does not affect functional compatibility.
