DF33-2S-3.3C Equivalent & Substitute Parts

Part Overview

The DF33-2S-3.3C is a 2-position rectangular connector receptacle housing manufactured by Hirose Electric Co Ltd, designed for applications requiring 0.130" (3.30mm) pitch connections with crimp termination and latch lock fastening. This part operates as a free-hanging in-line connector with female socket contacts and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent active alternatives is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF33-2S-3.3C is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 2 positions at 0.130" (3.30mm) spacing
• Termination & Fastening: Crimp contact termination with latch lock fastening
• Mounting Configuration: Free hanging in-line mounting
• Electrical & Environmental Compliance: RoHS compliance and MSL rating

The substitute part DF33C-2S-3.3C maintains identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: DF33C-2S-3.3C is active and available, whereas DF33-2S-3.3C is obsolete. The color difference (Natural vs. White) is a cosmetic variation that does not affect functional compatibility.

Engineering Selection Recommendations

The DF33C-2S-3.3C is the direct functional equivalent for the obsolete DF33-2S-3.3C. Selection of the substitute part is justified by:

• Product Status: DF33C-2S-3.3C maintains active production status with confirmed inventory availability (938 pcs), ensuring long-term procurement reliability
• Regulatory Compliance: Both parts meet RoHS requirements; DF33C-2S-3.3C carries ROHS3 compliance, representing current regulatory alignment
• Electrical & Mechanical Equivalence: Identical connector type, position count, pitch, contact configuration, termination method, and fastening mechanism ensure direct interchangeability
• Environmental Ratings: Both parts carry MSL 1 (Unlimited) rating, confirming equivalent moisture sensitivity performance
• Export Classification: Both parts share EAR99 classification, maintaining consistent export compliance

The DF33C-2S-3.3C is suitable for direct replacement in applications currently using the DF33-2S-3.3C without design modification.

Frequently Asked Questions (FAQ)

Q: Can DF33C-2S-3.3C be used as a direct replacement for DF33-2S-3.3C?

A: Yes. Both parts share identical specifications for connector type, position count, pitch, contact configuration, termination method, and fastening mechanism. The DF33C-2S-3.3C is electrically and mechanically interchangeable with the DF33-2S-3.3C.

Q: What is the significance of the color difference between Natural and White?

A: Color is a cosmetic attribute that does not affect electrical or mechanical performance. The color difference reflects manufacturing variations between the obsolete and active series but does not impact functional compatibility.

Q: Why is DF33-2S-3.3C classified as obsolete?

A: Obsolete status indicates that the part is no longer in active production. The DF33C-2S-3.3C represents the current active equivalent within the EnerBee™ DF33 series family.

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

A: Both parts are RoHS compliant. The DF33C-2S-3.3C carries ROHS3 compliance, representing alignment with current regulatory standards. Both parts maintain identical MSL 1 (Unlimited) ratings and EAR99 export classification.

Q: What is the packaging difference?

A: The DF33-2S-3.3C packaging is not specified in available documentation. The DF33C-2S-3.3C is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Are contacts included with these connector housings?

A: No. Both the DF33-2S-3.3C and DF33C-2S-3.3C are connector housings only. Contacts must be sourced separately and crimped according to Hirose specifications.
