DF33-5S-3.3C Equivalent & Substitute Parts

Part Overview

The DF33-5S-3.3C is a 5-position rectangular connector housing manufactured by Hirose Electric Co Ltd, part of the EnerBee™ DF33 series. This receptacle connector features a 0.130" (3.30mm) pitch and is designed for free-hanging in-line mounting with crimp contact termination and latch lock fastening. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF33-5S-3.3C is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 5 positions at 0.130" (3.30mm) spacing
• Mounting & Termination: Free-hanging in-line mounting with crimp termination
• Fastening Mechanism: Latch lock fastening
• Electrical & Environmental Compliance: RoHS compliance and MSL rating

The substitute part DF33C-5S-3.3C maintains identical electrical and mechanical specifications across all critical parameters. The primary difference is the housing color (Natural vs. White) and the transition from the obsolete DF33 series to the active DF33C series, which represents a product line evolution by the manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The DF33C-5S-3.3C is the direct substitute for the obsolete DF33-5S-3.3C. Both parts maintain identical electrical and mechanical specifications across all critical connector parameters: 5-position receptacle configuration, 0.130" (3.30mm) pitch, crimp termination, and latch lock fastening.

The DF33C-5S-3.3C is recommended for new designs and replacement applications due to its active product status. Both parts are RoHS compliant with MSL rating of 1 (Unlimited), ensuring compliance with current environmental and reliability standards. The transition from the DF33 series to the DF33C series represents a manufacturer product line update with no functional impact on connector performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Can DF33C-5S-3.3C directly replace DF33-5S-3.3C in existing assemblies?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: connector type, position count, pitch, mounting configuration, termination method, and fastening mechanism. The housing color difference (Natural vs. White) does not affect electrical performance or mechanical compatibility.

Q: What is the primary reason for substitution?

A: The DF33-5S-3.3C is obsolete. The DF33C-5S-3.3C is the active equivalent from Hirose Electric Co Ltd and is the recommended part for procurement and new designs.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are RoHS compliant and carry an MSL rating of 1 (Unlimited). Environmental and regulatory compliance is maintained across the substitution.

Q: Does the housing color change affect connector function?

A: No. Housing color is a cosmetic attribute and does not impact electrical performance, mechanical fit, or contact reliability. The color difference reflects the product line evolution from DF33 to DF33C.

Q: What is the packaging difference?

A: The DF33-5S-3.3C is listed with unspecified packaging, while the DF33C-5S-3.3C is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are contacts included with these connector housings?

A: No. Both parts are housings only. Contacts must be procured separately and are not included with either part number.
