• Pitch spacing: 0.197" (5.00mm)
• Row configuration: 3 rows at 0.197" (5.00mm) spacing
• Current rating: 7.5A minimum
• Voltage rating: 600V minimum
• Contact type: Female socket
• Contact finish at mating interface: Gold

Mechanical Parameters:

• Connector type: Header
• Mounting type: Through hole
• Termination method: Solder
• Insulation material: Polyamide (PA), Nylon
• Flammability rating: UL94 V-0 minimum

Environmental Parameters:

• Operating temperature range: -55°C to 130°C minimum
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all these criteria are considered direct substitutes and are electrically and mechanically interchangeable.

Parameter Comparison

Engineering Selection Recommendations

The 207526-9 is a direct functional substitute for the 207526-3. Both connectors share identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch spacing, contact configuration, current and voltage ratings, and operating temperature range.

The primary differences between these parts are non-functional in nature:

Product Status: The 207526-3 is obsolete, while the 207526-9 is active. Selection of the 207526-9 ensures access to current manufacturing and ongoing component availability.

Compliance: The 207526-9 is RoHS Compliant, whereas the 207526-3 is marked as not applicable. For applications subject to RoHS requirements, the 207526-9 satisfies regulatory compliance requirements.

Contact Finish - Post: The 207526-3 features tin-lead plating on the post, while the 207526-9 uses tin plating. Both finishes provide equivalent electrical performance and solder joint reliability for through-hole termination applications.

Packaging: The 207526-9 is supplied in tray packaging, which differs from the main part specification. Packaging selection does not affect electrical or mechanical compatibility.

For new designs, production continuity, and compliance with current regulatory standards, the 207526-9 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are the 207526-3 and 207526-9 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 9-position configuration, 0.197" (5.00mm) pitch, 7.5A current rating, and 600V voltage rating. They are electrically interchangeable in all applications.

Q: What is the difference in contact finish between these parts?

A: The 207526-3 uses tin-lead plating on the post (solder tail), while the 207526-9 uses tin plating. Both finishes are suitable for solder termination and provide equivalent electrical performance. The tin finish on the 207526-9 reflects RoHS compliance requirements.
