MDF7-23P-2.54DS(56) Equivalent & Substitute Parts

Part Overview

The MDF7-23P-2.54DS(56) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-board applications. This 23-position connector operates at 3A current rating and 250V voltage rating with a 0.100" (2.54mm) pitch. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The MDF7-23P-2.54DS(56) has one identified substitute within the MDF7 series: MDF7-23P-2.54DS(96). Substitution eligibility is determined by the following critical parameters:

• Pitch and Position Count: Both parts maintain 0.100" (2.54mm) pitch with 23 positions, ensuring mechanical and electrical compatibility at the connector interface level.
• Electrical Ratings: Both parts support 3A current and 250V voltage operation, meeting the same power delivery requirements.
• Contact Configuration: Both use male pin contacts with square contact shape and gold-plated mating surfaces.
• Insulation Material and Temperature Range: Both employ PBT insulation rated UL94 V-0 with identical -35°C ~ 85°C operating temperature range.
• Compliance: Both are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating.

The primary difference lies in connector style: the main part (56) is configured for board-to-board applications, while the substitute (96) is configured for board-to-cable/wire applications. This distinction affects mechanical mounting and mating interface design but does not alter the core electrical or thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-23P-2.54DS(96) is the designated substitute for the obsolete MDF7-23P-2.54DS(56). Selection of the substitute part is justified on the following basis:

• Product Status: The substitute maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.
• Electrical and Thermal Equivalence: Both parts meet identical current (3A), voltage (250V/250VAC), and temperature (-35°C ~ 85°C) specifications, confirming functional compatibility in electrical circuits.
• Compliance Alignment: Both parts carry RoHS compliance certification and UL94 V-0 flammability rating, meeting the same regulatory and safety requirements.
• Series Continuity: Both parts belong to the MDF7 series with matching pitch (2.54mm), position count (23), and contact configuration (male pin, square shape, gold-plated brass).

The primary consideration for implementation is the connector style difference: the substitute is configured for board-to-cable/wire connections rather than board-to-board. This requires evaluation of the specific application interface requirements to confirm mechanical compatibility with the mating connector or cable assembly.

Frequently Asked Questions (FAQ)

Q: Can MDF7-23P-2.54DS(96) directly replace MDF7-23P-2.54DS(56) in existing designs?

A: Electrical and thermal compatibility is confirmed. However, the connector style difference (board-to-cable/wire versus board-to-board) requires verification that the mating interface and mechanical mounting are compatible with your specific application. The 23-position, 2.54mm pitch, and male pin configuration remain identical.

Q: What is the significance of the connector style difference between these parts?

A: The style designation indicates the intended mating interface. The (56) variant is designed for board-to-board connections, while the (96) variant is designed for board-to-cable/wire connections. This affects the physical form factor and mounting approach but does not alter electrical performance or contact specifications.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts support 3A current rating and 250V voltage operation. The substitute (96) specifies 250VAC, while the main part (56) specifies 250V; both are suitable for the same voltage class applications.

Q: Why is the main part listed as obsolete?

A: Product obsolescence is determined by the manufacturer and typically reflects discontinuation of production. The active status of the substitute ensures continued availability for new designs and system support.

Q: Are there any packaging differences between these parts?

A: The main part (56) has no specified packaging designation, while the substitute (96) is packaged in bags. This affects receiving and storage procedures but does not impact 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, meeting identical regulatory and safety requirements.
