• Pitch spacing (0.100" / 2.54mm)
• Row configuration (2 rows at 0.100" spacing)
• Voltage rating (100VDC minimum)
• Contact type (Forked)

Mechanical Compatibility:

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

Regulatory Compliance:

• RoHS3 compliance
• Moisture Sensitivity Level 1

The substitute parts 188275-6 and 7-188275-6 maintain all critical electrical and mechanical parameters while offering active product status and enhanced operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 188275-6 and 7-188275-6 provide direct functional equivalence to the obsolete 7-2178711-6 across all critical electrical and mechanical parameters. The substitute parts maintain identical connector geometry, pitch spacing, contact configuration, and voltage rating while offering active product status.

188275-6 (Tape & Reel Packaging): This variant is supplied in Tape & Reel format, suitable for high-volume automated assembly operations. It carries active product status and ROHS3 compliance certification.

7-188275-6 (Cut Tape Packaging): This variant is supplied in Cut Tape format, suitable for lower-volume or mixed-component assembly requirements. It includes Pick and Place feature designation and carries active product status with ROHS3 compliance and REACH Unaffected status.

Both substitutes provide enhanced operating temperature range (-40°C to 105°C versus -30°C to 85°C) and UL94 V-0 flammability rating, offering improved performance margins for demanding applications. Contact material differs (Phosphor Bronze versus Brass), representing a material upgrade in the substitute parts.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 188275-6 and 7-188275-6 electrically interchangeable with 7-2178711-6?

A: Yes. Both substitute parts maintain identical electrical specifications including 6-position configuration, 0.100" pitch spacing, 100VDC voltage rating, and forked contact design. All three parts are rated for the same voltage and operate within compatible electrical parameters.

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

A: The primary difference is packaging format. 188275-6 is supplied in Tape & Reel (TR) format for automated high-volume assembly. 7-188275-6 is supplied in Cut Tape (CT) format for lower-volume or mixed-component applications. Both parts are electrically and mechanically identical.

Q: Can I use these substitutes in existing designs without PCB layout modifications?

A: Yes. The substitute parts maintain identical mechanical dimensions, pitch spacing (0.100"), row spacing (0.100"), insulation height (0.209"), and surface mount termination. PCB footprints designed for 7-2178711-6 are compatible with both substitute parts.

Q: Why do the substitute parts have a wider operating temperature range?

A: The substitute parts (188275-6 and 7-188275-6) are rated for -40°C to 105°C operation, compared to the main part's -30°C to 85°C range. This represents an enhanced specification in the active product variants.

Q: What is the significance of the UL94 V-0 flammability rating on the substitute parts?

A: The substitute parts carry UL94 V-0 certification, indicating superior flame resistance of the insulation material. The main part does not specify a flammability rating. This represents an additional compliance certification on the substitute parts.

Q: Are there any compatibility concerns with contact material differences?

A: The main part uses Brass contacts while the substitute parts use Phosphor Bronze contacts. Both materials are compatible with tin plating and maintain equivalent electrical performance for this connector application. Phosphor Bronze represents a material upgrade in the substitute parts.

Q: Which substitute part should I select for new designs?

A: Selection between 188275-6 and 7-188275-6 depends on assembly volume and process requirements. For high-volume automated assembly, 188275-6 (Tape & Reel) is appropriate. For lower-volume or mixed-component assembly, 7-188275-6 (Cut Tape) with Pick and Place feature is appropriate. Both are active products with equivalent electrical and mechanical performance.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both substitute parts carry ROHS3 compliance certification, matching the compliance status of the main part.
