DF33-4S-3.3C Equivalent & Substitute Parts

Part Overview

The DF33-4S-3.3C is a 4-position rectangular connector housing manufactured by Hirose Electric Co Ltd, designed for receptacle applications with a 0.130" (3.30mm) pitch. This connector belongs to the EnerBee™ DF33 series and features a natural color housing 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

The DF33C-4S-3.3C qualifies as a direct substitute for the DF33-4S-3.3C based on the following critical parameters:

• Connector Type & Contact Configuration: Both are receptacle housings with female socket contacts
• Position Count & Pitch: Both feature 4 positions at 0.130" (3.30mm) pitch
• Mounting & Termination: Both use free hanging (in-line) mounting with crimp contact termination
• Fastening Mechanism: Both employ latch lock fastening
• Electrical & Environmental Compliance: Both are RoHS compliant and rated MSL 1 (Unlimited)

The primary difference is the housing color (natural vs. white) and product status (obsolete vs. active). The DF33C-4S-3.3C represents the active production equivalent within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

The DF33C-4S-3.3C is the appropriate substitute for the obsolete DF33-4S-3.3C. Both connectors share identical electrical and mechanical specifications across all critical parameters: 4-position receptacle configuration, 0.130" (3.30mm) pitch, crimp termination, and latch lock fastening.

The DF33C-4S-3.3C offers the advantage of active product status with current manufacturing support and improved compliance certification (ROHS3 vs. RoHS Compliant). The housing color difference (white vs. natural) does not affect electrical or mechanical compatibility. The specified operating temperature range (-35°C ~ 85°C) and PBT insulation material of the substitute part provide documented performance parameters for the active product line.

Frequently Asked Questions (FAQ)

Q: Are DF33-4S-3.3C and DF33C-4S-3.3C mechanically compatible?

A: Yes. Both connectors feature identical mounting type (free hanging in-line), pitch (0.130" / 3.30mm), position count (4), and fastening mechanism (latch lock). They are mechanically interchangeable.

Q: Does the housing color difference affect electrical performance?

A: No. Housing color is a cosmetic attribute and does not impact electrical characteristics, signal integrity, or connector function.

Q: What is the significance of the product status change from Obsolete to Active?

A: The DF33C-4S-3.3C is the current production equivalent. Active status ensures ongoing manufacturing availability, technical support, and compliance with current regulatory standards.

Q: Are both parts RoHS compliant?

A: Yes. The DF33-4S-3.3C is RoHS Compliant, and the DF33C-4S-3.3C is ROHS3 Compliant. Both meet RoHS requirements.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are contacts included with these connector housings?

A: No. Both the DF33-4S-3.3C and DF33C-4S-3.3C are housings only. Contacts must be procured separately and crimped into the housing.
