DF22R-3P-7.92DSA(05) Equivalent & Substitute Parts

Part Overview

The DF22R-3P-7.92DSA(05) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting in board-to-cable/wire applications. This connector features a 3-position vertical configuration with 0.312" (7.92mm) pitch spacing and is rated for 25A at 1000V. The part is currently obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF22R-3P-7.92DSA(05) is determined by the following critical parameters:

• Connector Type & Configuration: Header, male pin contact, 3-position, 0.312" (7.92mm) pitch
• Mounting & Termination: Through-hole solder termination with latch holder fastening
• Shrouding & Mechanical: Shrouded 4-wall design with board guide feature
• Electrical Ratings: 1000V voltage rating and copper alloy contact material
• Material Compliance: UL94 V-0 flammability rating and polyamide insulation

The identified substitute parts maintain these core parameters while offering improvements in product status (active vs. obsolete) and contact finish specifications. Variations in contact finish material (tin-copper vs. gold) and operating temperature ranges are secondary parameters that do not prevent functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both DF22R-3P-7.92DSA(23) and DF22R-3P-7.92DSA(53) are suitable substitutes for the obsolete DF22R-3P-7.92DSA(05) based on maintained electrical and mechanical compatibility.

DF22R-3P-7.92DSA(23) is recommended for applications requiring active product status with extended operating temperature range (-55°C to 85°C) and gold contact finish. This part maintains RoHS compliance and offers improved availability.

DF22R-3P-7.92DSA(53) is recommended for applications requiring active product status with extended operating temperature range (-55°C to 85°C), gold contact finish on both mating and post surfaces, and board lock feature. This part carries ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment for current manufacturing standards.

Both substitutes maintain the core electrical ratings (1000V, copper alloy contacts), mechanical configuration (3-position, 7.92mm pitch, through-hole solder termination), and safety certifications (UL94 V-0) of the original part.

Frequently Asked Questions (FAQ)

Q: Can DF22R-3P-7.92DSA(23) and DF22R-3P-7.92DSA(53) be used interchangeably with DF22R-3P-7.92DSA(05)?

A: Both parts maintain the same connector type, position count, pitch spacing, mounting method, and electrical ratings. The primary differences are contact finish material (gold vs. tin-copper) and operating temperature range (-55°C to 85°C vs. -35°C to 85°C). Interchangeability depends on your specific application requirements for contact finish and temperature performance.

Q: What is the significance of the contact finish difference between tin-copper and gold?

A: Contact finish affects corrosion resistance and mating cycle durability. Gold-plated contacts (DF22R-3P-7.92DSA(23) and (53)) provide superior corrosion resistance and are preferred for applications with extended shelf life or harsh environmental exposure. Tin-copper contacts (original part) are suitable for standard industrial applications with controlled storage conditions.

Q: Does the board lock feature in DF22R-3P-7.92DSA(53) affect mechanical compatibility?

A: The board lock feature is an additional mechanical enhancement that does not prevent compatibility with mating connectors designed for the standard latch holder configuration. The board lock provides additional retention security without affecting the fundamental mating interface.

Q: Are there packaging differences between these parts?

A: DF22R-3P-7.92DSA(05) and (23) are supplied without specified packaging, while DF22R-3P-7.92DSA(53) is supplied in bag packaging. This difference does not affect electrical or mechanical performance.

Q: Which substitute part should I select for new designs?

A: For new designs, DF22R-3P-7.92DSA(53) is the preferred choice due to active product status, extended operating temperature range, enhanced contact finish specifications, board lock feature, and current regulatory compliance (ROHS3, REACH unaffected). DF22R-3P-7.92DSA(23) is suitable as an alternative if the board lock feature is not required.
