Key Parameters

Substitute Part Grouping Explanation

Substitution for the 76347-441 is determined by the following critical parameters:

• Wire gauge compatibility: 28-32 AWG
• Contact type: Socket
• Termination method: Crimp
• Connector category: Rectangular connectors
• Moisture sensitivity level: MSL 1 (Unlimited)
• Contact finish: Tin or tin-lead

The substitute parts identified maintain these core electrical and mechanical specifications. The primary distinction between the main part and substitutes involves contact finish composition (tin-lead versus tin), contact finish thickness, RoHS compliance status, and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The 76347-441LF represents the direct equivalent within the Amphenol ICC product line, maintaining the same series designation while transitioning to an active product status and RoHS compliance. This part is suitable for applications requiring Amphenol ICC connector compatibility with modern regulatory requirements.

The TE Connectivity AMP Connectors parts 167021-3 and 167024-3 provide cross-manufacturer substitution options. Both maintain the required electrical specifications (28-32 AWG, socket, crimp termination, tin finish) and MSL 1 rating. The 167021-3 is supplied in Tape & Reel packaging, while 167024-3 is supplied in bulk packaging. Both parts carry active product status and RoHS compliance certifications, with 167024-3 specifically certified to ROHS3 standards.

Selection between these substitutes should be based on connector series compatibility requirements within the target application, packaging format availability, and regulatory compliance mandates specific to the end-use environment.

Frequently Asked Questions (FAQ)

Q: Can 76347-441LF directly replace 76347-441 in existing designs?

A: Yes. The 76347-441LF maintains identical wire gauge (28-32 AWG), socket type, crimp termination, and MSL 1 rating. The primary differences are contact finish composition (tin versus tin-lead) and finish thickness. Compatibility depends on application-specific requirements for contact finish specifications.

Q: What is the difference between tin and tin-lead finishes in these socket contacts?

A: The 76347-441 uses tin-lead finish at 196.9µin (5.00µm) thickness. The 76347-441LF, 167021-3, and 167024-3 use tin finish at 78.7µin (2.00µm) thickness. Tin-lead finishes are typically associated with legacy designs, while tin finishes align with modern RoHS compliance requirements.

Q: Are TE Connectivity parts 167021-3 and 167024-3 interchangeable with each other?

A: Both parts maintain identical electrical specifications and comply with the same standards. The primary difference is packaging format: 167021-3 is supplied in Tape & Reel, while 167024-3 is supplied in bulk. Selection depends on procurement and assembly process requirements.

Q: What does MSL 1 (Unlimited) mean for these socket contacts?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning these components have unlimited shelf life under standard storage conditions and do not require special moisture control during handling or storage.

Q: Why is the 76347-441 listed as obsolete?

A: The 76347-441 is obsolete due to its RoHS non-compliant status and tin-lead finish composition. Modern regulatory requirements and industry standards have transitioned to RoHS-compliant alternatives with tin finishes, making the 76347-441LF and cross-manufacturer equivalents the preferred options for new and ongoing applications.
