DF9-23P-1V(54) Equivalent & Substitute Parts

Part Overview

The DF9-23P-1V(54) is a 23-position rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount applications with center strip contacts and gold plating. This connector is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The DF9-23P-1V(69) serves as the direct active substitute, maintaining identical electrical and mechanical specifications while offering improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

The DF9-23P-1V(69) qualifies as a direct substitute for the DF9-23P-1V(54) based on the following critical parameters:

• Electrical Compatibility: Identical number of positions (23), pitch (0.039" / 1.00mm), and contact finish (gold)
• Mechanical Compatibility: Matching connector type (header, center strip contacts), mounting type (surface mount), height above board (0.130" / 3.30mm), and mated stacking height (4.3mm)
• Functional Features: Both include board guide and solder retention features
• Environmental Rating: Both rated at MSL 1 (unlimited moisture sensitivity level)
• Series Consistency: Both belong to the DF9 series from Hirose Electric Co Ltd

The substitution is based on identical form, fit, and function across all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The DF9-23P-1V(69) is the appropriate selection for applications currently using or specifying the DF9-23P-1V(54). The substitute part maintains complete electrical and mechanical compatibility while offering the following advantages:

• Active Product Status: The DF9-23P-1V(69) is actively manufactured and supported, ensuring long-term availability and supply chain continuity
• RoHS Compliance: The substitute meets RoHS requirements, whereas the original part is non-compliant, making it suitable for regulated markets and applications with environmental compliance mandates
• Specified Contact Finish Thickness: The DF9-23P-1V(69) provides documented contact finish thickness (8.00µin / 0.203µm), enabling precise reliability calculations
• Standard Packaging: Supplied in Tape & Reel format, facilitating automated assembly processes

No electrical or mechanical redesign is required when transitioning from DF9-23P-1V(54) to DF9-23P-1V(69).

Frequently Asked Questions (FAQ)

Q: Are the DF9-23P-1V(54) and DF9-23P-1V(69) pin-compatible?

A: Yes. Both connectors have identical pin counts (23 positions), pitch (0.039" / 1.00mm), and row configuration (2 rows). They are fully pin-compatible and require no PCB layout modifications.

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

A: The primary differences are product status and compliance. The DF9-23P-1V(54) is obsolete and RoHS non-compliant, while the DF9-23P-1V(69) is an active product that meets RoHS requirements. The DF9-23P-1V(69) also specifies contact finish thickness (8.00µin), whereas the original part does not.

Q: Can I use DF9-23P-1V(69) as a direct replacement in existing designs?

A: Yes. The DF9-23P-1V(69) is a direct substitute with identical form, fit, and function. No design changes are necessary for PCB layout, mating connectors, or electrical specifications.

Q: What packaging is available for the substitute part?

A: The DF9-23P-1V(69) is supplied in Tape & Reel (TR) packaging, which is standard for surface mount connectors and compatible with automated pick-and-place assembly equipment.

Q: Are there any environmental or compliance considerations when switching parts?

A: The DF9-23P-1V(69) is RoHS compliant, making it suitable for applications subject to RoHS regulations. Both parts maintain the same MSL 1 rating (unlimited moisture sensitivity), indicating no special storage or handling requirements.

Q: Is the contact finish thickness difference significant?

A: The DF9-23P-1V(69) specifies contact finish thickness at 8.00µin (0.203µm). The original part does not provide this specification. For most applications, this difference is not functionally significant, but the documented thickness on the substitute part enables more precise reliability and wear analysis if required.
