DF9-9P-1V(20) Equivalent & Substitute Parts

Part Overview

The DF9-9P-1V(20) is a 9-position rectangular connector header manufactured by Hirose Electric Co., Ltd., designed for surface mount applications with center strip contacts and tin plating. This connector is classified as obsolete, which necessitates identification of active equivalent parts to ensure continued design support and procurement availability. The DF9-9P-1V(32) serves as the direct functional substitute, maintaining identical electrical and mechanical specifications while offering active product status and improved compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

The DF9-9P-1V(32) qualifies as a direct substitute for the DF9-9P-1V(20) based on the following critical parameters:

• Connector Type & Configuration: Both parts are 9-position headers with center strip contacts in a 2-row arrangement
• Electrical Interface: Identical pitch of 0.039" (1.00mm) ensures mechanical and electrical compatibility
• Mounting Technology: Both employ surface mount construction with identical board guide and solder retention features
• Physical Dimensions: Matching height above board (0.130" / 3.30mm) and mated stacking heights (4.3mm)
• Contact Material: Tin plating on both parts ensures compatible soldering and environmental performance
• Moisture Sensitivity: Both rated MSL 1 (Unlimited), indicating equivalent moisture handling characteristics

The substitution is based solely on functional equivalence across these specified parameters. The primary distinction is product status: DF9-9P-1V(20) is obsolete, while DF9-9P-1V(32) maintains active status.

Engineering Selection Recommendations

The DF9-9P-1V(32) is the appropriate selection for new designs and procurement activities. This part maintains full functional equivalence to the DF9-9P-1V(20) across all critical electrical and mechanical parameters while offering the following advantages:

• Active Product Status: DF9-9P-1V(32) is actively manufactured and supported by Hirose Electric, ensuring long-term availability and supply chain stability
• RoHS Compliance: DF9-9P-1V(32) meets RoHS requirements, aligning with current regulatory standards and environmental directives
• Standardized Packaging: Available in Tape & Reel format, facilitating automated assembly processes

For existing designs currently using DF9-9P-1V(20), direct substitution with DF9-9P-1V(32) requires no circuit modifications or PCB redesign due to identical pin configuration, pitch, and mounting footprint.

Frequently Asked Questions (FAQ)

Q: Are DF9-9P-1V(20) and DF9-9P-1V(32) pin-compatible?

A: Yes. Both parts feature identical 9-position, 2-row configurations with 0.039" (1.00mm) pitch and surface mount construction. Pin-to-pin compatibility is complete.

Q: Can DF9-9P-1V(32) be used as a direct replacement on existing PCBs designed for DF9-9P-1V(20)?

A: Yes. Matching height above board (0.130" / 3.30mm), mated stacking heights (4.3mm), and board guide features ensure mechanical compatibility without PCB modification.

Q: What is the difference between the (20) and (32) designations?

A: The numeric suffix indicates packaging configuration. DF9-9P-1V(20) uses standard packaging, while DF9-9P-1V(32) is supplied in Tape & Reel format. Electrical and mechanical specifications remain identical.

Q: Does the RoHS compliance difference affect substitution?

A: DF9-9P-1V(32) is RoHS compliant, making it suitable for applications subject to RoHS directives. The DF9-9P-1V(20) is non-compliant. For new designs, DF9-9P-1V(32) is the preferred choice.

Q: Are there any soldering or assembly differences between these parts?

A: No. Both parts employ identical tin contact finish, board guide, and solder retention features. Standard surface mount assembly processes apply to both.

Q: What is the MSL rating for both parts?

A: Both DF9-9P-1V(20) and DF9-9P-1V(32) are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
