DF59SN-1P-FC(21) Equivalent & Substitute Parts

Part Overview

The DF59SN-1P-FC(21) is a Solid State Lighting (SSL) connector manufactured by Hirose Electric Co Ltd, designed as a 1-position board-to-board adapter bridge. This connector is currently in active product status and is RoHS compliant with MSL 1 rating. The part is widely used in SSL applications requiring reliable push-mount, snap-in connectivity with a 3A current capacity and 350V voltage rating.

Substitute parts become necessary when the primary part experiences supply constraints, inventory depletion, or when design flexibility allows for compatible alternatives within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF59SN-1P-FC(21) is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Must be Adapter, Bridge configuration with Board to Board mounting
• Electrical Specifications: Voltage rating of 350V and current rating of 3A
• Mechanical Compatibility: 1-position configuration with Push Mount, Snap-In mounting type
• Material Specifications: Liquid Crystal Polymer (LCP) housing with Brass contacts and Tin finish
• Environmental Compliance: RoHS compliance and MSL 1 rating
• Operating Temperature: -35°C ~ 105°C range

The substitute part DF59S-1P-FC(24) meets all these critical parameters, making it functionally equivalent for direct substitution in applications where the DF59SN-1P-FC(21) is specified.

Parameter Comparison

Engineering Selection Recommendations

The DF59SN-1P-FC(21) is the preferred primary selection due to its active product status, ensuring long-term availability and manufacturing support from Hirose Electric Co Ltd.

The DF59S-1P-FC(24) is electrically and mechanically equivalent and meets all RoHS and MSL compliance requirements. However, this part carries an obsolete product status, indicating discontinued manufacturing. Selection of the DF59S-1P-FC(24) should be limited to applications where existing inventory is available and supply chain continuity is not a concern.

Both parts share identical electrical ratings (350V, 3A), operating temperature range (-35°C ~ 105°C), and mechanical mounting specifications. The DF59S-1P-FC(24) includes halogen-free LCP housing material, which may be advantageous for specific environmental or regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can DF59S-1P-FC(24) be used as a direct replacement for DF59SN-1P-FC(21)?

A: Yes. Both parts are electrically and mechanically equivalent with identical voltage ratings (350V), current ratings (3A), operating temperature ranges (-35°C ~ 105°C), and mounting configurations (Push Mount, Snap-In). Both are RoHS compliant with MSL 1 rating.

Q: What is the difference between DF59SN-1P-FC(21) and DF59S-1P-FC(24)?

A: The primary difference is product status. DF59SN-1P-FC(21) is active, while DF59S-1P-FC(24) is obsolete. The DF59S-1P-FC(24) specifies halogen-free LCP housing material. All electrical and mechanical parameters are identical.

Q: Why is DF59S-1P-FC(24) marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. This part may still be available through existing inventory channels but should not be selected for new designs requiring long-term supply assurance.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in Cut Tape (CT) packaging format.

Q: What certifications apply to both parts?

A: Both parts are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity level rating. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040.
