Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 2178711-6 is based on strict equivalence across the following critical parameters:

Electrical Compatibility:

• Connector type (Receptacle)
• Number of positions (6)
• Mating pitch (0.100" / 2.54mm)
• Row configuration (2 rows with 0.100" spacing)
• Voltage rating (100VDC)
• Contact type (Forked)

Mechanical Compatibility:

• Mounting type (Surface Mount)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Insulation material (Polyamide PA46, Nylon 4/6, Glass Filled)
• Insulation height (0.209" / 5.30mm)
• Series designation (Micro-MaTch)

Regulatory Compliance:

• RoHS3 compliance
• Moisture Sensitivity Level 1

The substitute parts 188275-6 and 7-188275-6 maintain full electrical and mechanical compatibility with the original 2178711-6 while offering active product status and enhanced operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Cut Tape Packaging): The 7-188275-6 is the primary substitute for the 2178711-6, offering identical packaging format (Cut Tape) and mounting compatibility. Both parts maintain the same surface mount solder termination and push-pull fastening mechanism. The 7-188275-6 provides active product status with extended operating temperature range (-40°C to 105°C versus -30°C to 85°C) and UL94 V-0 flammability certification. Contact material differs (Phosphor Bronze versus Brass), which does not affect electrical or mechanical compatibility within the specified voltage and current parameters.

For High-Volume Applications (Tape & Reel Packaging): The 188275-6 serves as an alternative when tape and reel packaging is preferred for automated assembly processes. This part maintains all electrical and mechanical specifications identical to 7-188275-6 while offering higher inventory availability (2947 units in stock). The tape and reel format accommodates pick-and-place equipment integration.

Compliance Considerations: Both substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating, ensuring compatibility with standard PCB assembly and storage protocols. The UL94 V-0 flammability rating on substitute parts exceeds the original specification, providing enhanced material safety characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 188275-6 or 7-188275-6 be used as direct replacements for the 2178711-6?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications across all critical parameters: 6-position receptacle configuration, 0.100" (2.54mm) pitch, 2-row layout with 0.100" row spacing, surface mount termination, push-pull fastening, and 100VDC voltage rating. The Micro-MaTch series designation confirms compatibility within the connector family.

Q: What is the difference between the 188275-6 and 7-188275-6?

A: The primary difference is packaging format. The 188275-6 is supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly. The 7-188275-6 is supplied in Cut Tape (CT) format, matching the original 2178711-6 packaging. Both parts are electrically and mechanically identical.

Q: Does the contact material change (Brass to Phosphor Bronze) affect compatibility?

A: No. The contact material change from Brass to Phosphor Bronze does not affect electrical or mechanical compatibility. Both materials provide adequate conductivity and durability for the specified 100VDC application. The change represents an internal design improvement without altering connector performance or mating characteristics.

Q: What is the significance of the extended operating temperature range on substitute parts?

A: The substitute parts operate across -40°C to 105°C, compared to the original -30°C to 85°C range. This extended range provides greater thermal margin for applications subject to wider environmental conditions. Applications operating within the original temperature range experience no change in performance.

Q: Are there packaging considerations when switching from 2178711-6 to substitute parts?

A: Yes. The original 2178711-6 uses Cut Tape (CT) packaging. The 7-188275-6 maintains this format. The 188275-6 uses Tape & Reel (TR) format, which requires compatible pick-and-place equipment. Select packaging based on assembly process requirements and equipment capabilities.

Q: Do the substitute parts maintain RoHS3 compliance?

A: Yes. Both 188275-6 and 7-188275-6 are ROHS3 compliant, matching the original 2178711-6 specification. Moisture Sensitivity Level 1 (Unlimited) is maintained across all parts, ensuring compatibility with standard PCB assembly and storage protocols.

Q: What is the inventory status for each part?

A: The 2178711-6 (obsolete) has 1550 units in stock. The 188275-6 (active) has 2947 units available. The 7-188275-6 (active) has 2200 units available. Active parts provide long-term supply continuity for new designs and production requirements.
